Objectives. We estimated the seroprevalence of both acute and chronic HIV infection by using a random sample of emergency department (ED) patients from a region of the United States with low-to-moderate HIV prevalence.Methods. This cross-sectional seroprevalence study consecutively enrolled patients aged 18 to 64 years within randomly selected sampling blocks in a Midwestern urban ED in a region of lower HIV prevalence in 2008 to 2009. Participants were compensated for providing a blood sample and health information. After de-identification, we assayed samples for HIV antibody and nucleic acid.Results. There were 926 participants who consented and enrolled. Overall, prevalence of undiagnosed HIV was 0.76% (95% confidence interval [CI] = 0.30%, 1.56%). Three participants (0.32%; 95% CI = 0.09%, 0.86%) were nucleic acid–positive but antibody-negative and 4 (0.43%; 95% CI = 0.15%, 1.02%) were antibody-positive.Conclusions. Even when the absolute prevalence is low, a considerable proportion of undetected HIV cases in an ED population are acute. Identification of acute HIV in ED settings should receive increased priority.HIV screening is recommended by the US Centers for Disease Control and Prevention as an essential component of the nation’s HIV prevention effort.1,2 Emergency departments (EDs) are particularly emphasized as venues for HIV screening.3–5 Emergency departments serve more than 100 million patients annually, readily accessing vulnerable populations with a high prevalence of undetected HIV.1,4–8To date, most attention has been focused on detection of HIV in the chronic phase, after seroconversion, by assay for antibodies. Yet identification of patients during acute HIV infection could have a significant impact on further transmission.9,10 Testing for acute HIV infection is accomplished by assays that detect viral proteins or viral genetic material before antibody detection is possible. This testing is more expensive, complex, or may delay results compared with antibody testing.9,11,12 Despite these disadvantages, screening for acute HIV is increasingly suggested by various authors.9,13–19 Acute HIV infection is thought to contribute disproportionately to HIV incidence because of high viral replication and increased infectiousness during this phase.15,20–22 Diagnosis prompts many individuals to reduce transmission behaviors,23 and partner notification efforts may be more successful.24 There is also renewed interest in treatment during acute HIV infection, to lower infectiousness and improve long-term patient health outcomes.21,25–27 In light of these benefits, screening for acute HIV infection may ultimately be cost-effective and worthy of increased logistical challenges.9,28Unfortunately, the controversies and implementation barriers in HIV screening have yet to be fully resolved,29–35 particularly in ED settings where patient volumes exceed capacity and acute stabilization takes precedence over preventive health.36–38 Screening in the ED for acute HIV infection will be even more challenging than screening for chronic HIV if it entails additional complexity and expense. Motivation to surmount such barriers is likely to be less in regions of lower HIV prevalence, in which disease incidence would also be presumed lower. Improving our understanding of acute HIV epidemiology in ED settings is fundamental for guiding potential implementation of ED screening interventions targeting acute HIV infection. We estimated the seroprevalence of both acute and chronic HIV infection by using a random sample of ED patients from a low-to-moderate HIV prevalence region of the United States.  相似文献

To ascertain HCV testing practices among US prisons and jails, we conducted a survey study in 2012, consisting of medical directors of all US state prisons and 40 of the largest US jails, that demonstrated a minority of US prisons and jails conduct routine HCV testing. Routine voluntary HCV testing in correctional facilities is urgently needed to increase diagnosis, enable risk-reduction counseling and preventive health care, and facilitate evaluation for antiviral treatment.There are an estimated 4 to 7 million persons in the United States infected with HCV.1,2 Morbidity and mortality from HCV are increasing and in 2007, death from HCV exceeded that from HIV infection for the first time.3,4 Persons who inject drugs are at increased risk for HCV infection and for being incarcerated. Multiple studies have demonstrated high HCV prevalence rates among persons behind bars.5–7 In 2010, the Institute of Medicine (IOM) called for the development of comprehensive viral hepatitis services for incarcerated populations including offering testing, hepatitis B virus vaccination, education, and medical management in partnership with community providers.8Despite the Centers for Disease Control and Prevention (CDC) releasing HCV testing recommendations in 1998 and subsequent recommendations for prevention and control of viral hepatitis within correctional facilities in 2003,9-10 recent studies estimate that 50% of persons infected with HCV are unaware of their infection,11–14 thus reducing opportunities for risk-reduction counseling and treatment. In response to this, the CDC updated HCV testing recommendations for the US general population in 2012, which added at least 1-time testing among persons born between 1945 and 1965, now commonly referred to as the “birth cohort” screening recommendations.15 However, the 2012 recommendations did not provide a specific testing recommendation for incarcerated individuals. Given the increased prevalence of HCV among criminal justice populations, we conducted a survey among US prisons and jails to gain a better understanding of current HCV testing practices within correctional facilities.  相似文献

Objectives. We assessed whether directly observed fluoxetine treatment reduced depression symptom severity and improved HIV outcomes among homeless and marginally housed HIV-positive adults in San Francisco, California, from 2002 to 2008.Methods. We conducted a nonblinded, randomized controlled trial of once-weekly fluoxetine, directly observed for 24 weeks, then self-administered for 12 weeks (n = 137 persons with major or minor depressive disorder or dysthymia). Hamilton Depression Rating Scale score was the primary outcome. Response was a 50% reduction from baseline and remission a score below 8. Secondary measures were Beck Depression Inventory-II (BDI-II) score, antiretroviral uptake, antiretroviral adherence (measured by unannounced pill count), and HIV-1 RNA viral suppression (< 50 copies/mL).Results. The intervention reduced depression symptom severity (b = −1.97; 95% confidence interval [CI] = −0.85, −3.08; P < .001) and increased response (adjusted odds ratio [AOR] = 2.40; 95% CI = 1.86, 3.10; P < .001) and remission (AOR = 2.97; 95% CI = 1.29, 3.87; P < .001). BDI-II results were similar. We observed no statistically significant differences in secondary HIV outcomes.Conclusions. Directly observed fluoxetine may be an effective depression treatment strategy for HIV-positive homeless and marginally housed adults, a vulnerable population with multiple barriers to adherence.Depressive, pain, and substance use disorders are highly prevalent among persons living with HIV/AIDS1,2 and among the homeless and marginally housed.3–5 The triple diagnosis of depression, HIV, and substance use poses unique treatment challenges for clinicians: successful management of one condition is often dependent on successful management of the others, and the optimal sequencing of depression treatment, substance use treatment, and stabilization of psychosocial comorbidities remains unclear. Adherence to the entire continuum of HIV care is often hampered by depression6–8 and substance use.9,10 For homeless persons, the need to address subsistence concerns such as obtaining food and shelter may not only adversely affect mental well-being11 but may also divert attention away from medication adherence and regular clinic attendance.12 Timely and effective depression treatment is critical for HIV-positive persons, because depression has been associated with CD4+ T-lymphocyte cell count decline,13 progression to AIDS,14 and AIDS-related mortality.15 Yet depression remains pervasively underdiagnosed and undertreated among the homeless16–18 and among HIV-positive persons.19,20Depression treatment might be expected to improve virological or immunologic outcomes through improved adherence, but this has not been conclusively demonstrated.21–23 We therefore sought to determine whether treatment with once-weekly fluoxetine reduced depression symptom severity among homeless and marginally housed persons with comorbid depression and HIV. Because this population faces many psychosocial barriers to successful medication adherence,12,24 in addition to depression,25 we employed a directly observed treatment strategy similar to that used for treatment and management of patients with tuberculosis and HIV.26 This strategy reduced the potential for incomplete adherence to reduce the effectiveness of antidepressant treatment. A secondary aim was to determine whether depression treatment improved antiretroviral therapy (ART) uptake among persons eligible for treatment and ART adherence and viral suppression among treated persons.  相似文献

Objectives. We evaluated the efficacy of a hepatitis care coordination intervention to improve linkage to hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccination and clinical evaluation of hepatitis C virus (HCV) infection among methadone maintenance patients.Methods. We conducted a randomized controlled trial of 489 participants from methadone maintenance treatment programs in San Francisco, California, and New York City from February 2008 through June 2011. We randomized participants to a control arm (n = 245) and an intervention arm (n = 244), which included on-site screening, motivational-enhanced education and counseling, on-site vaccination, and case management services.Results. Compared with the control group, intervention group participants were significantly more likely (odds ratio [OR] = 41.8; 95% confidence interval [CI] = 19.4, 90.0) to receive their first vaccine dose within 30 days and to receive an HCV evaluation within 6 months (OR = 4.10; 95% CI = 2.35, 7.17). A combined intervention adherence outcome that measured adherence to HAV–HBV vaccination, HCV evaluation, or both strongly favored the intervention group (OR = 8.70; 95% CI = 5.56, 13.61).Conclusions. Hepatitis care coordination was efficacious in increasing adherence to HAV–HBV vaccination and HCV clinical evaluation among methadone patients.Viral hepatitis is a major public health problem among drug users in the United States. Drug users are at high risk of infection with hepatitis A, B, and C viruses (HAV, HBV, and HCV, respectively) through unsterile injection practices and high-risk sexual activity.1–3 HCV infection can be acquired rapidly by injection drug users, with prevalence rates of 70% or higher among recent-onset injectors.4,5 Cirrhosis, hepatocellular carcinoma, and death are important sequelae of HCV and chronic HBV infection.6,7 Superimposed HBV and HAV infection may exacerbate liver disease among those with chronic HCV infection.8 HIV infection can accelerate disease progression in HCV- and HBV-infected persons.9–11 Given that a significant proportion of this population remains at risk for these infections, HAV–HBV vaccination programs that effectively engage drug users are needed.2,12 Treatment options for HCV are rapidly improving with the introduction of direct-acting antivirals (e.g., telaprevir and boceprevir) and the prospect of interferon-free regimens.13–16The integration of primary medical care and case management services within drug treatment programs has been associated with increased utilization of outpatient health care services among HIV- and HCV-seropositive drug users. Studies have found increased rates of the use of HIV/AIDS- and HCV-related medical care services in the methadone treatment setting17–19; however, most drug treatment programs do not have the infrastructure to provide on-site HCV treatment.20 Despite advances in HCV treatment, many HCV-positive drug users are not engaged in HCV care,21,22 and many drug users experience missed opportunities for HAV and HBV vaccination.2,23Drug users experience multiple complex individual, social, and structural barriers to HCV evaluation and treatment. Barriers include lack of knowledge about available effective treatments, low perceived risk of potential long-term adverse health consequences, fear of possible side effects of treatment, high treatment costs, lack of insurance, negative peer norms regarding HCV medications, medical mistrust, and potential provider concerns about treating active drug users.24–31 As has been observed for HIV infection, with HCV infection there is a cascade of care, with decreasing proportions of infected persons knowing their status, having had a clinical evaluation, being engaged in care, being on treatment, completing treatment, and having an optimal virological response.21,30,32HCV drug efficacy trials focus on optimizing outcomes among those treated, whereas adherence interventions frequently focus on assisting individuals to complete initiated therapy. For drug users with HCV infection, the initial steps in the cascade of care, including screening, identifying those HCV positive, and engaging infected persons in care, remain a substantial gap.21 Care coordination approaches such as case management and patient navigation services have shown promise in engaging and retaining patients in cancer screening and care and have been used in HIV primary care with promising but inconsistent results.33–39 There is a need for rigorously designed research to examine the efficacy of care coordination approaches such as case management and patient navigation as a strategy for improving the efficiency of the HCV cascade of care.We evaluated the impact of a hepatitis care coordination model integrated in the methadone maintenance treatment (MMT) setting on the following primary outcomes: (1) receipt of the first dose of HAV–HBV vaccine and (2) adherence to an initial appointment with a hepatitis C health care provider. We hypothesized that hepatitis care coordination, including on-site screening, education and counseling, motivational interviewing, on-site vaccination, and case management, would increase rates of adherence to HAV–HBV vaccination and initial appointment with a hepatitis C health care provider more than a control intervention that reflected standard recommendations for the care of drug users.40  相似文献

Objectives. We assessed the relation of childhood sexual abuse (CSA), intimate partner violence (IPV), and depression to HIV sexual risk behaviors among Black men who have sex with men (MSM).Methods. Participants were 1522 Black MSM recruited from 6 US cities between July 2009 and December 2011. Univariate and multivariable logistic regression models were used.Results. Participants reported sex before age 12 years with someone at least 5 years older (31.1%), unwanted sex when aged 12 to 16 years (30%), IPV (51.8%), and depression (43.8%). Experiencing CSA when aged 12 to 16 years was inversely associated with any receptive condomless anal sex with a male partner (adjusted odds ratio [AOR] = 0.50; 95% confidence interval [CI] = 0.29, 0.86). Pressured or forced sex was positively associated with any receptive anal sex (AOR = 2.24; 95% CI = 1.57, 3.20). Experiencing CSA when younger than 12 years, physical abuse, emotional abuse, having been stalked, and pressured or forced sex were positively associated with having more than 3 male partners in the past 6 months. Among HIV-positive MSM (n = 337), CSA between ages 12 and 16 years was positively associated with having more than 3 male partners in the past 6 months.Conclusions. Rates of CSA, IPV, and depression were high, but associations with HIV sexual risk outcomes were modest.Despite significant medical advances, the HIV epidemic remains a health crisis in Black communities. The Black population represents only 14% of the total US population but accounted for 44% of all new HIV infection (68.9 of 100 000) in 2010.1 Black men who have sex with men (MSM) are disproportionately impacted by HIV compared with other racial/ethnic groups of MSM.1,2 Male-to-male sexual contact accounted for 72% of new infections among all Black men.1 Young Black MSM (aged 13–24 years) have a greater number of new infections than any other age or racial group among MSM.1 Researchers have been challenged with developing HIV prevention strategies for Black MSM.3–7 Higher frequencies of sexual risk behaviors, substance use, and nondisclosure of sexual identities do not adequately explain this disparity.8,9 High rates of sexually transmitted infections (STIs), which facilitate HIV transmission, and undetected or late diagnosis of HIV infection only partially explain disproportionate HIV rates.8Researchers have begun to examine a constellation of health factors that may contribute to HIV among MSM. For example, syndemic theory or the interaction of epidemics synergistically, such as intimate partner violence (IPV) and depression, may help explain HIV-related sexual risk behaviors among Black MSM.9 Childhood sexual abuse (CSA), IPV, and mental health disorders including depression may comprise such a constellation and warrant further exploration.Experiences of CSA have been identified as being associated with negative sexual health outcomes, with MSM reporting higher CSA rates than the general male population.10–12 Men with CSA experiences are more likely than men without CSA experiences to engage in high-risk sexual behaviors,13–21 have more lifetime sexual partners,13–16 use condoms less frequently,13,14,16 and have higher rates of STIs,13,14,17 exchanging sex for drugs or money,13,14,17 HIV,13,14 alcohol and substance use,13–21 and depression.13–15,18,21 Such findings suggest that sexual risk reduction counseling may need to be tailored for MSM with CSA experiences.15Childhood sexual abuse histories have also been correlated with sexual revictimization, including IPV.22–24 One study with population-based estimates of CSA found that gay and bisexually identified men had higher odds of reporting CSA (9.5 and 12.8, respectively) compared with heterosexual men.25 For sexual minority men, CSA histories were associated with higher HIV and STI incidence.25 However, research examining CSA, revictimization, and sexual risk behaviors is lacking among Black MSM.In one existing study, Black and Latino MSM with CSA histories identified their trauma experiences as influencing their adult sexual decision-making.26 Among Black MSM in 2 additional studies, emotional distress and substance use were attributed to having CSA experiences (Leo Wilton, PhD, written communication, October 2, 2013).27 In an ethnically diverse sample of 456 HIV-positive MSM, CSA was associated with insertive and receptive condomless anal sex.19Similar to CSA, IPV has not been extensively examined among MSM or Black MSM,28 but may be associated with sexual risk behaviors. Intimate partner violence is defined as a pattern of controlling, abusive behavior within an intimate relationship that may include physical, psychological or emotional, verbal, or sexual abuse.29 Little research exists on IPV among same-sex couples despite incidence rates being comparable to or greater than that of heterosexual women.28,30–34 Important IPV information comes from the National Intimate Partner and Sexual Violence Survey, a nationally representative survey for experiences of sexual violence, stalking, and IPV among men and women in the United States.28 Among men who experienced rape, physical violence, or stalking by an intimate partner, perpetrator differences by gender were found among gay, bisexual, and heterosexual men; 78% of bisexual and 99.5% of heterosexual men reported having only female perpetrators, and 90.7% of gay men reported having only male perpetrators.28 Being slapped, pushed, or shoved by an intimate partner during their lifetime was reported by gay (24%), bisexual (27%), and heterosexual (26.3%) men.28Intimate partner violence has been linked to condomless anal sex, HIV infection, substance use, CSA, and depression.35–37 Being an HIV-positive MSM has been linked with becoming a victim of IPV.38,39 Welles et al. found that being an African American MSM who initially disclosed having male partners and early life sexual abuse experiences was associated with IPV victimization.39 Wilton found that a high percentage of Black MSM reported IPV histories: emotional abuse (48.3%), physical abuse (28.3%), sexual abuse (21.7%), and stalking abuse (29.2%; Leo Wilton, PhD, written communication, October 2, 2013). Such findings lend to the importance of exploring, both independently and together, the association of CSA and IPV with sexual risk behaviors.Some studies have reported the influence of mental health (e.g., depression) on sexual risk behaviors among MSM,9,40,41 whereas others have not corroborated such findings.42 Greater rates of depression among MSM than among non-MSM samples43–45 and elevated rates of depression and anxiety among Black MSM have been reported.46 The Urban Men’s Health Study, a cross-sectional sample of MSM in 4 US cities, did not find a significant relationship between high depressive symptoms and condomless anal sex.42 However, the EXPLORE study, a randomized behavioral intervention for MSM in 6 US cities, supported the association between moderate depressive symptoms and an increased risk for HIV infection.47 Moderate levels of depression and higher rates of sexual risk were also reported for HIV-infected MSM over time.48 Another study conducted with 197 Black MSM found that moderate depressive symptoms were associated with having condomless anal sex with a serodiscordant casual partner.49 These mixed findings support the need to better understand the relationship between the severity of depression (i.e., moderate vs severe) and HIV risk behaviors.The HIV Prevention Trials Network 061 study, also known as the BROTHERS (Broadening the Reach of Testing, Health Education, Resources, and Services) Project, was a multisite study to determine the feasibility and acceptability of a multicomponent intervention for Black MSM. The current analysis aims to assess the prevalence of CSA, IPV, and depressive symptomology, and examine the relationships between these factors and insertive and receptive condomless anal sex and number of sexual partners in a large cohort of Black MSM.  相似文献

Objectives. We examined the associations between depressive symptoms and sexual identity and behavior among women with or at risk for HIV.Methods. We analyzed longitudinal data from 1811 participants in the Women’s Interagency HIV Study (WIHS) from 1994 to 2013 in Brooklyn and the Bronx, New York; Chicago, Illinois; Washington, DC; and Los Angeles and San Francisco, California, by comparing depressive symptoms by baseline sexual identity and ongoing sexual behavior. We controlled for age, socioeconomic status, violence history, and substance use.Results. In separate analyses, bisexual women and women who reported having sex with both men and women during follow-up had higher unadjusted odds of depressive symptoms compared with heterosexuals and women who reported only having male sexual partners (adjusted odd ratio [AOR] = 1.36; 95% confidence interval [CI]  = 1.10, 1.69 and AOR = 1.21; 95% CI = 1.06, 1.37, respectively). Age was a significant effect modifier in multivariable analysis; sexual minority women had increased odds of depressive symptoms in early adulthood, but they did not have these odds at midlife. Odds of depressive symptoms were lower among some sexual minority women at older ages.Conclusions. Patterns of depressive symptoms over the life course of sexual minority women with or at risk for HIV might differ from heterosexual women and from patterns observed in the general aging population.Depression is a major health concern for women. According to the Centers for Disease Control and Prevention (CDC), 10% of US women reported any depression and 5% reported major depression in the previous 2 weeks.1 Depression has been reported in 19% to 62%2–4 of HIV-infected women and is associated with reduced cognitive function,5 decreased adherence to highly active antiretroviral therapy (HAART),6 higher rates of unprotected sex among substance users,7 and increased mortality.2,6Women with or at risk for HIV are often exposed to factors such as poverty,8 substance use, and violence,9–11 which can independently and jointly contribute to depression. A recent study found that any combination of intimate partner violence (IPV), substance use, and HIV infection increased the odds of depression.12 Lower socioeconomic status (SES) in women12 and HIV infection4,5 were also independently associated with depression. However, studies showed no association among HIV stage, HAART use,4,8 CD4 count,8,13 or viral load and depression.4,8,13There is a strong association between sexual minority status (i.e., women who identify as lesbian or bisexual or have female sex partners) and poor mental health. In a US survey, lifetime major depression was reported by 42% of lesbians, 52% of bisexuals, and 27% of heterosexual women (P < .01); in the same study, major depression was reported by 15% of women who have sex with women (WSW), 51% of women who have sex with men and women (WSMW), and 27% of women who have sex with men (WSM; P < .01).14 In this study, we examined 2 aspects of sexual orientation15–17: sexual identity and sexual behavior. Although sexual attraction is also considered part of an individual’s sexual orientation, data on attraction was not collected in the original study.Despite the strong association between sexual minority status and depression, it is unknown whether sexual minority status acts as an independent predictor or effect modifier of depressive symptoms among women affected by HIV, substance use, and violence. Our original hypothesis was that lesbian, bisexual, and WSMW (but not WSW) would have higher odds of depression, with race/ethnicity acting as a potential effect modifier.  相似文献

Objectives. Although people with HIV experience significant oral health problems, many consistently identify oral health as an unmet health care need. We conducted a randomized controlled trial to evaluate the impact of a dental case management intervention on dental care use.Methods. We evaluated the intervention according to self-reported dental care use at 6-, 12-, and 18-month follow-ups. Multivariable logistic models with generalized estimating equations were used to assess the effects of the intervention over time.Results. The odds of having a dental care visit were about twice as high in the intervention group as in the standard care group at 6 months (adjusted odds ratio [OR] = 2.52; 95% confidence interval [CI] = 1.58, 4.08) and 12 months (adjusted OR = 1.98; 95% CI = 1.17, 3.35), but the odds were comparable in the 2 groups by 18 months (adjusted OR = 1.07; 95% CI = 0.62, 1.86). Factors significantly associated with having a dental care visit included frequent physician visits and dental care referrals.Conclusions. We demonstrated that a dental case management intervention targeting people with HIV was efficacious but not sustainable over time. Barriers not addressed in the intervention must be considered to sustain its use over time.In the era of antiretroviral therapy, people with HIV are living longer and the treatment of associated medical and oral manifestations of the disease has shifted to a chronic disease model.1 Previous studies have shown that a person living with HIV/AIDS is more likely than a person without the disease to experience oral health problems.2–5 Furthermore, the oral health problems of individuals with HIV can be more severe and difficult to treat than those of the general population and may also contribute to the onset of opportunistic infections.5The oral health complications associated with HIV are well documented,2–6 and oral manifestations are increasingly being recognized as markers for monitoring treatment efficacy and predicting treatment failure.7 Oral manifestations, including Kaposi’s sarcoma, necrotizing ulcerative periodontitis, oral hairy leukoplakia, and candidiasis, may be present in up to 50% of people with HIV and 80% of people diagnosed with AIDS,5,6 and may predict low CD4 counts.8 In addition, individuals living with HIV/AIDS may experience difficulty in maintaining adequate salivary flow, which affects chewing, swallowing, and the ability to take medication.4 Chronic use of highly active antiretroviral therapy can also contribute to diminished salivary flow as well as an increased risk of oral candidiasis and oral hairy leukoplakia.9Throughout the 1990s, a series of study findings highlighted the unmet needs for dental care among people with HIV infection.10–14 This gap in oral health care services was corroborated by findings from the oral health component of the HIV Cost and Services Utilization Study,15 which demonstrated that unmet dental needs were twice as common as unmet medical needs among HIV-positive adults16,17 and led to a national call to action to improve access to oral health care.18 That study also showed that approximately half of people living with HIV had dental insurance, and those without dental insurance had greater unmet needs for dental services.17,19,20Recently published findings suggest that an unmet need still persists. One example is an initiative, funded by the Health Resources and Services Administration, that included 2469 people living with HIV who had not received dental care during the preceding year. Nearly half of these individuals (48%) reported an unmet dental need since their HIV diagnosis, 52% had not seen a dentist in more than 2 years, and 63% rated the health of their teeth and gums as fair or poor.21,22 An earlier investigation involving baseline data from the study presented here showed that oral health problems and symptoms were very prevalent among our study population, with 63% of participants having experienced an oral health impact very often or fairly often in the preceding 4 weeks.23Barriers to dental care use among individuals living with HIV include fear of dental care, HIV-specific stigma, fear of disclosing their HIV status to health care providers, perceived cost barriers, and poor adherence to medical guidance.20,22,24–31 Compounding patient access barriers, dental care providers may be reluctant to treat patients with HIV owing to fears of HIV transmission and associated stigma.32–36Previous research conducted in Florida revealed that more than one third of people with HIV do not discuss oral health with their primary care providers.37 Although clinical guidelines recommend that HIV care providers examine the oral cavity during initial and interim physical examinations of people living with HIV, this still may not be a regular clinical practice.37 To address underuse of oral health care services among individuals with HIV, we evaluated the efficacy of an intervention that linked individuals to dental care. The sample comprised a population of HIV-positive individuals in south Florida who had received HIV primary care but had not received oral health services in the preceding 12 months.  相似文献

Objectives. We estimated HIV prevalence among men who have sex with men (MSM) and transgender women in Bogotá, Colombia, and explored differences between HIV-positive individuals who are aware and unaware of their serostatus.Methods. In this cross-sectional 2011 study, we used respondent-driven sampling (RDS) to recruit 1000 MSM and transgender women, who completed a computerized questionnaire and received an HIV test.Results. The RDS-adjusted prevalence was 12.1% (95% confidence interval [CI] = 8.7, 15.8), comparable to a previous RDS-derived estimate. Among HIV-positive participants, 39.7% (95% CI = 25.0, 54.8) were aware of their serostatus and 60.3% (95% CI = 45.2, 75.5) were unaware before this study. HIV-positive–unaware individuals were more likely to report inadequate insurance coverage, exchange sex (i.e., sexual intercourse in exchange for money, goods, or services), and substance use than other participants. HIV-positive–aware participants were least likely to have had condomless anal intercourse in the previous 3 months. Regardless of awareness, HIV-positive participants reported more violence and forced relocation experiences than HIV-negative participants.Conclusions. There is an urgent need to increase HIV detection among MSM and transgender women in Bogotá. HIV-positive–unaware group characteristics suggest an important role for structural, social, and individual interventions.Colombia ranks second among countries in Latin America in HIV prevalence, with estimates ranging from 0.7% to 1.1% of the adult population.1 Men who have sex with men (MSM) represent the group most strongly affected, with prevalence of 18% to 20% based on venue-based convenience samples2,3 and 15% based on respondent-driven sampling (RDS).4 Colombia has a long history of armed conflict, and the pervasive conditions of violence, internal displacement, and poverty can be relevant to HIV transmission.5 “Social cleansing” by armed groups has been aimed at MSM and transgender women, as well as people living with HIV,5 and the stigma associated with homosexuality and HIV is widespread and inherent in structural inequalities in Colombia.6,7 Social epidemiological models posit that HIV is influenced by such structural (e.g., civil unrest, migration) and social factors (e.g., social networks, community attitudes), as well as individual characteristics (e.g., psychological characteristics, behavior).8Public health efforts emphasize the importance of detecting and treating undiagnosed HIV as a means of reducing HIV incidence.9–11 In the United States, approximately 20% of HIV-positive individuals are thought to be unaware of their infection, but this group is estimated to be responsible for nearly half of new transmissions.12 There is limited research concerning awareness of serostatus in Latin America. Undiagnosed infection was found to be 89% among HIV-positive MSM sampled in Peru in 2011,13 and rates are likely to be high in Colombia because of low levels of testing,6 including among MSM.4,14 Recent studies of MSM in France, Peru, and the United States have found associations between undiagnosed infection and demographic characteristics such as age, income, and education13,15,16; risk behaviors14,17,18; family or intimate partner violence19; and health insurance coverage.20 We also examined awareness in relation to violence and forced relocation, conditions specific to the Colombian context.Respondent-driven sampling was developed as a means of obtaining unbiased estimates from hidden populations,21–23 and it has been shown to capture a more diverse24,25 and hidden26 group of MSM than time–location or snowball sampling. Research has suggested, however, that biases can occur.27–29Our current study and a study conducted by the United Nations Population Fund and the Colombian Ministry of Health and Social Protection (UNFPA/MSPS) were independently funded at approximately the same time to address the limited information about behavioral risk and HIV prevalence among Colombian MSM. Comparison of findings from the 2 studies provides evidence concerning reliability of the RDS-derived prevalence estimates. We estimated HIV prevalence among MSM and transgender women in Bogotá, Colombia, examined reliability of RDS-derived estimates in relation to the UNFPA/MSPS study,4 and investigated the role of the social and structural context of Colombia in both prevalence and awareness of positive serostatus.  相似文献

Objectives. We examined trends and organizational-level correlates of the availability of HCV testing in opioid treatment programs.Methods. We used generalized ordered logit models to examine associations between organizational characteristics of 383 opioid treatment programs from the 2005 and 2011 National Drug Abuse Treatment System Survey and HCV testing availability.Results. Between 2005 and 2011, the proportion of opioid treatment programs offering HCV testing increased but largely because of increases in off-site referrals rather than on-site testing. HCV testing availability was higher in opioid treatment programs affiliated with a hospital and those receiving federal funds. Opioid treatment programs providing both methadone and buprenorphine were more likely to offer any HCV testing, whereas opioid treatment programs providing only buprenorphine treatment were less likely to offer on-site testing. HCV testing availability was associated with more favorable staff-to-client ratios.Conclusions. The increasing use of off-site referrals for HCV testing in opioid treatment programs likely limits opportunities for case finding, prevention, and treatment. Declines in federal funding for opioid treatment programs may be a key determinant of the availability of HCV testing in opioid treatment programs.HCV is the most common blood-borne infection in the United States. An estimated 3.2 million people in the United States are chronically infected with HCV,1 making it 3 to 5 times more frequent than HIV.2 Results from a recent study showed that HCV has surpassed HIV as a cause of death in the United States.3 New HCV treatment regimens that are more effective and have fewer side effects have recently become available.4 Unfortunately, fewer than half of the patients living with HCV are aware of their infection.5 This is because infected persons tend to be asymptomatic: in some cases, signs of the disease do not manifest for decades.6 It is thus important to encourage and offer extensive opportunities for HCV testing, especially to the most at-risk populations.6Advancements in testing technologies (HCV rapid testing)7 and recommendations for the identification of HCV in the general population (i.e., individuals born between 1945 and 1965) present opportunities for increasing the availability of HCV testing.8 Testing could foster increased case finding, as well as earlier linkages to HCV care and treatment services. Ensuring access to HCV testing and increasing awareness of HCV status also could help promote the adoption of preventive behaviors: for example, engaging in safer injection practices or other protective behaviors. Ultimately, this may also have a positive influence on compliance with substance abuse treatment and abstinence.9The Centers for Disease Control and Prevention (CDC) recommends routine HCV antibody (anti-HCV) testing for injection drug users (IDUs).3,10 IDUs are particularly at risk for HCV infection as a result of sharing and reusing of needles or other injection paraphernalia.6 The estimated anti-HCV prevalence among IDUs ranges from 35% to 65%, depending on factors such as geography and rate of injection drug use.11 Unfortunately, despite the CDC recommendation, IDUs have very low rates of uptake for HCV testing and treatment.12One factor that may account for such low testing rates is that IDUs less frequently use preventive health care services than do other population groups.13 Outpatient substance abuse treatment programs are one exception: the number of IDUs entering treatment programs has increased in recent years.14 Because injection drug use is strongly associated with opioid use (e.g., heroin), opioid treatment programs are an especially important setting for HCV testing, counseling, prevention, and links to medical care. In the case of HIV testing and case management, on-site services in substance abuse treatment programs have been associated with high-quality prevention, increased service use, earlier initiation of treatment, declines in disease transmission, improved treatment outcomes for substance use disorders, and links to ancillary services.15–17 Hence integrating HCV testing with substance abuse treatment services, particularly in opioid treatment programs, may have similar beneficial effects and is crucial for addressing the HCV epidemic in the United States.18Unfortunately, trends in the availability of HCV testing services in opioid treatment programs across the nation are not well understood.19,20 Large gaps exist in the availability of on-site HCV testing in opioid treatment programs,21–24 with programs that have the largest proportion of IDUs among their clients being less likely to offer on-site HCV testing, even when phlebotomists were on staff.24 Opioid treatment programs often prefer to refer their clients to off-site facilities for HCV testing. Yet off-site referrals for testing and treatment of HCV are associated with significant reductions in the uptake of these services.25There is also an urgent need to examine the organizational-level characteristics of treatment programs that may serve as facilitators or barriers to the availability of HCV testing services, either on-site or off-site, in the nation’s opioid treatment programs.26 HCV testing services may not be offered in opioid treatment programs in the United States for several potential reasons. First, opioid treatment programs may lack the required financial resources, including reimbursement and funding, to implement testing services.23,27–29 Second, treatment programs may not have the human resource capacity (e.g., low staff-to-client ratio) to effectively offer both substance abuse treatment services and ancillary services. Similarly, the ownership and affiliations of opioid treatment programs may influence the extent to which they can offer HCV testing services. For example, publicly owned opioid treatment programs might be more likely to have a prevention-driven mission, whereas hospital-affiliated opioid treatment programs may have access to networks that enable them to provide HCV testing services. Organizational-level predictors for HIV testing services in drug abuse treatment programs have been examined extensively, but similar national studies for the provision of HCV testing services are scarce.19,30–32We first describe trends in HCV testing availability in the nation’s opioid treatment programs between 2005 and 2011. We then examine the role of organizational factors in promoting the availability of HCV testing services among opioid treatment programs.  相似文献

Objectives. We investigated the association between posttraumatic stress disorder (PTSD) and incident heart failure in a community-based sample of veterans.Methods. We examined Veterans Affairs Pacific Islands Health Care System outpatient medical records for 8248 veterans between 2005 and 2012. We used multivariable Cox regression to estimate hazard ratios and 95% confidence intervals for the development of heart failure by PTSD status.Results. Over a mean follow-up of 7.2 years, veterans with PTSD were at increased risk for developing heart failure (hazard ratio [HR] = 1.47; 95% confidence interval [CI] = 1.13, 1.92) compared with veterans without PTSD after adjustment for age, gender, diabetes, hyperlipidemia, hypertension, body mass index, combat service, and military service period. Additional predictors for heart failure included age (HR = 1.05; 95% CI = 1.03, 1.07), diabetes (HR = 2.54; 95% CI = 2.02, 3.20), hypertension (HR = 1.87; 95% CI = 1.42, 2.46), overweight (HR = 1.72; 95% CI = 1.25, 2.36), obesity (HR = 3.43; 95% CI = 2.50, 4.70), and combat service (HR = 4.99; 95% CI = 1.29, 19.38).Conclusions. Ours is the first large-scale longitudinal study to report an association between PTSD and incident heart failure in an outpatient sample of US veterans. Prevention and treatment efforts for heart failure and its associated risk factors should be expanded among US veterans with PTSD.Posttraumatic stress disorder (PTSD) is a psychiatric illness that affects approximately 7.7 million Americans aged older than 18 years.1 PTSD typically results after the experience of severe trauma, and veterans are at elevated risk for the disorder. The National Vietnam Veterans Readjustment Study reported the prevalence of PTSD among veterans who served in Vietnam as 15.2% among men and 8.1% among women.2 In fiscal year 2009, nearly 446 045 Veterans Administration (VA) patients had a primary diagnosis of PTSD, a threefold increase since 1999.3 PTSD is of growing clinical concern as evidence continues to link psychiatric illnesses to conditions such as arthritis,4 liver disease,5 digestive disease,6 and cancer.6 When the postwar health status of Vietnam veterans was examined, those with PTSD had higher rates of diseases of the circulatory, nervous, digestive, musculoskeletal, and respiratory systems.7The evidence linking PTSD to coronary heart disease (CHD) is substantial.8–10 Veterans with PTSD are significantly more likely to have abnormal electrocardiograph results, myocardial infarctions, and atrioventricular conduction deficits than are veterans without PTSD.11 In a study of 605 male veterans of World War II and the Korean War, CHD was more common among veterans with PTSD than among those without PTSD.12 Worldwide, adults exposed to the disaster at Chernobyl experienced increased rates of CHD up to 10 years after the event,13 and studies of stressors resulting from the civil war in Lebanon found elevated CHD mortality.14,15Although the exact biological mechanism by which PTSD contributes to CHD remains unclear, several hypotheses have been suggested, including autonomic nervous system dysfunction,16 inflammation,17 hypercoagulability,18 cardiac hyperreactivity,19 altered neurochemistry,20 and co-occurring metabolic syndrome.16 One of the hallmark symptoms of PTSD is hyperarousal,21 and the neurobiological changes brought on from sustained sympathetic nervous system activation affect the release of neurotransmitters and endocrine function.22 These changes have negative effects on the cardiovascular system, including increased blood pressure, heart rate, and cardiac output.22,23Most extant literature to date examining cardiovascular sequelae has shown a positive association between PTSD and coronary artery disease.8–10 Coronary artery disease is well documented as one of the most significant risk factors for future development of heart failure.24 Despite burgeoning evidence for the role of PTSD in the development of coronary artery disease, there are few studies specifically exploring the relationship between PTSD and heart failure. Limited data suggest that PTSD imparts roughly a threefold increase in the odds of developing heart failure in both the general population5 and in a sample of the elderly.25 These investigations, however, have been limited by cross-sectional study design, a small proportion of participants with PTSD, and reliance on self-reported measures for both PTSD and heart failure.5,25 Heart failure is a uniquely large public health issue, as nearly 5 million patients in the United States are affected and there are approximately 500 000 new cases each year.26 Identifying predictors of heart failure can aid in early detection efforts while simultaneously increasing understanding of the mechanism behind development of heart failure.To mitigate the limitations of previous investigations, we undertook a large-scale prospective study to further elucidate the role of prevalent PTSD and development of incident heart failure among veterans, while controlling for service-related and clinical covariates. Many studies investigating heart failure have relied on inpatient records; we leveraged outpatient records to more accurately reflect the community burden of disease.  相似文献

Objectives. We report lessons derived from implementation of the Social Network Strategy (SNS) into existing HIV counseling, testing, and referral services targeting 18- to 64-year-old Black gay, bisexual, and other men who have sex with men (MSM).Methods. The SNS procedures used in this study were adapted from a Centers for Disease Control and Prevention–funded, 2-year demonstration project involving 9 community-based organizations (CBOs) in 7 cities. Under the SNS, HIV-positive and HIV-negative men at high risk for HIV (recruiters) were enlisted to identify and recruit persons from their social, sexual, or drug-using networks (network associates) for HIV testing. Sites maintained records of modified study protocols for ascertaining lessons learned. The study was conducted between April 2008 and May 2010 at CBOs in Washington, DC, and New York, New York, and at a health department in Baltimore, Maryland.Results. Several common lessons regarding development of the plan, staffing, training, and use of incentives were identified across the sites. Collectively, these lessons indicate use of SNS is resource-intensive, requiring a detailed plan, dedicated staff, and continual input from clients and staff for successful implementation.Conclusions. SNS may provide a strategy for identifying and targeting clusters of high-risk Black MSM for HIV testing. Given the resources needed to implement the strategy, additional studies using an experimental design are needed to determine the cost-effectiveness of SNS compared with other testing strategies.Approximately 1.1 million people are living with HIV in the United States and about 50 000 new infections occur each year.1 Gay, bisexual, and other men who have sex with men (MSM) remain the most affected subpopulation. Although constituting approximately 2% of the US population,2 MSM accounted for 63% of all new infections in 2010,3 61% of HIV diagnoses among men in 2010,4 and represent approximately 48% of people living with HIV.4Among MSM, Black MSM are disproportionately affected. Young (aged 13–24 years) Black MSM accounted for 55% of new infections among young MSM in 2010.3 There are more new HIV infections among 13- to 24-year-old Black MSM than among any other subgroup by race/ethnicity, age, and gender in the United States.3The available literature suggests that myriad individual, social, and contextual factors contribute to the HIV rates among young, Black MSM.5–13 These factors include a higher background prevalence of HIV in the community leading to a greater chance of exposure to an infected partner despite less risky behavior5–8; a higher prevalence of other sexually transmitted infections, like syphilis and gonorrhea, that might facilitate the acquisition and transmission of HIV5–8; limited access to treatment and health care6; stigma, homophobia, discrimination12; partner characteristics and risk behaviors5,9–11; and lack of awareness of individual or partner’s HIV status.5,11Awareness of HIV status is a critical step in addressing the HIV epidemic among young, Black MSM. Centers for Disease Control and Prevention (CDC) estimates that approximately 18% of the people living with HIV have not been diagnosed.14 Furthermore, of those living with HIV in 2009, 66% are linked to care, 37% retained in care, and 25% have a suppressed viral load.14 Individuals with consistently suppressed viral load experience reduced HIV-related morbidity and mortality and have a lower probability of transmitting the virus to others.14 Although Blacks are more likely to have ever been tested for HIV than other racial/ethnic groups in the United States, 2 in 5 have never been tested.15Additionally, many test too late in the course of their infection to receive maximum benefits from treatment.6 In 2008, more than one third of Blacks who were diagnosed with HIV were also diagnosed with AIDS within 1 year.15These data underscore the need for strategies to identify undiagnosed HIV positive, young, Black MSM. This paper presents results from a multisite study designed to evaluate the relative effectiveness of 3 strategies—alternate venue testing (AVT), the Social Network Strategy (SNS), and partner counseling and referral services (PCRS; now known as Partner Services)—for reaching and motivating previously undiagnosed, 18- to 64-year-old Black MSM to be tested for HIV and linked to medical care and prevention services. Applicants were required to meet the following eligibility criteria for funding: (1) conduct the study in a city with a Black population of at least 100 000 based on 2000 US Census data; (2) have an HIV counseling and testing program (CTR) that had been in existence for at least 3 years (prior to 2006) and that historically and currently provided services to Black men, including MSM; and (3) conduct PCRS or have a written agreement with the local health department to obtain aggregate PCRS data for Black MSM. Each of the funded sites had existing AVT programs that were expanded for this study to focus on Black MSM. All of the sites received SNS training and implemented this strategy into their existing CTR programs. The purpose of this article is to report common, cross-site lessons learned from implementation of SNS into existing HIV CTR services in New York City, New York; Baltimore, Maryland; and Washington, DC.  相似文献

Objectives. We investigated potential risk factors for active injection drug use (IDU) in an inner-city cohort of patients infected with hepatitis C virus (HCV).Methods. We used log-binomial regression to identify factors independently associated with active IDU during the first 3 years of follow-up for the 289 participants who reported ever having injected drugs at baseline.Results. Overall, 142 (49.1%) of the 289 participants reported active IDU at some point during the follow-up period. In a multivariate model, being unemployed (prevalence ratio [PR] = 1.93; 95% confidence interval [CI] = 1.24, 3.03) and hazardous alcohol drinking (PR = 1.67; 95% CI = 1.34, 2.08) were associated with active IDU. Smoking was associated with IDU but this association was not statistically significant. Patients with all 3 of those factors were 3 times as likely to report IDU during follow-up as those with 0 or 1 factor (PR = 3.3; 95% CI = 2.2, 4.9). Neither HIV coinfection nor history of psychiatric disease was independently associated with active IDU.Conclusions. Optimal treatment of persons with HCV infection will require attention to unemployment, alcohol use, and smoking in conjunction with IDU treatment and prevention.Hepatitis C virus (HCV) infection is a major cause of chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. About 130 million people are estimated to be infected worldwide with HCV,1 including 3.2 million in the United States,2 and mortality from HCV in the United States is increasing.3 Injection drug use (IDU) is the single most important risk factor for HCV infection in the United States 2,4 with an estimated 40% to 50% of infections attributable to IDU.5 Of increasing concern is the substantial proportion of HCV-infected patients who are coinfected with HIV.6 Because HIV and HCV are each transmitted by blood-contaminated needles and syringes, approximately 30% of all HIV-infected individuals are also infected with HCV1,7; in cohorts of intravenous drug users, the proportion of HCV-infected persons with HIV coinfection can be as high as 41%.8Because IDU is a significant risk factor for HCV transmission, ongoing drug abuse is common in HCV-infected populations. Such ongoing drug use has been documented as a potential barrier in managing the infection.9,10 Moreover, former IDUs can be concerned about relapse with performing self-injection as part of interferon treatment.11 Thus, understanding factors associated with active IDU may inform pragmatic approaches to improving acceptability of HCV treatment and increasing patients’ chances of successfully treating their disease.Other barriers to treatment of HCV infection have been described and are associated with IDU, such as alcohol use, psychiatric disease, and HIV coinfection.9,10,12–14 Concurrent alcohol abuse has, in some studies, distinguished persistence of IDU from cessation of IDU; however, in other reports, the association of heavy alcohol use did not remain after adjustment for known risk factors.15,16 Co-occurring mental disorders are frequently associated with poorer health and worse treatment outcomes among drug users and may lead to an increased level of drug use and riskier drug use behavior.17 HIV infection has been hypothesized to be associated with IDU in contrasting ways. Those who are HIV-infected may have more frequent contact with health services and thus referral to drug treatment; conversely, increased depression following diagnosis may lead to increased drug use.16Individual patterns of drug use vary over time. Whereas some studies have indicated a trend toward decreased IDU over time in longer-term cohort studies, others have found that many injection drug users are unable to maintain sustained cessation of IDU.17–23 In addition to the direct morbidity and mortality associated with IDU, continued use may make it more difficult for patients to effectively manage their disease. Evaluating predictors of ongoing IDU in these populations may help identify avenues to facilitate long-term cessation of IDU. Our goals were to investigate risk factors for active IDU in a cohort of patients infected with hepatitis C, with specific focus on alcohol use, smoking, psychiatric disease, and HIV coinfection.  相似文献

Objectives. We estimated HIV prevalence and risk factors among persons receiving mental health treatment in Philadelphia, Pennsylvania, and Baltimore, Maryland, January 2009 to August 2011.Methods. We used a multisite, cross-sectional design stratified by clinical setting. We tested 1061 individuals for HIV in university-based inpatient psychiatric units (n = 287), intensive case-management programs (n = 273), and community mental health centers (n = 501).Results. Fifty-one individuals (4.8%) were HIV-infected. Confirmed positive HIV tests were 5.9% (95% confidence interval [CI] = 3.7%, 9.4%) for inpatient units, 5.1% (95% CI = 3.1%, 8.5%) for intensive case-management programs, and 4.0% (95% CI = 2.6%, 6.1%) for community mental health centers. Characteristics associated with HIV included Black race, homosexual or bisexual identity, and HCV infection.Conclusions. HIV prevalence for individuals receiving mental health services was about 4 times as high as in the general population. We found a positive association between psychiatric symptom severity and HIV infection, indicating that engaging persons with mental illness in appropriate mental health treatment may be important to HIV prevention. These findings reinforce recommendations for routine HIV testing in all clinical settings to ensure that HIV-infected persons receiving mental health services are identified and referred to timely infectious disease care.People with serious mental illness (SMI) are at increased risk for being infected with HIV. Risk factors associated with HIV infection among persons with SMI mirror those in the general population and include unprotected sexual activity and injection drug use (IDU).1–5 Studies that estimated HIV prevalence from samples of patients with SMI during the 1990s and early 2000s found that HIV prevalence ranged from 1% to 23%.6–16 The wide variation in estimates has been attributed to small sample sizes, the use of regional convenience samples, differences in sampling frames, and inadequate adjustment for confounding effects of factors associated with HIV risk.17,18Analysis of administrative data indicates that many HIV-infected persons who receive Medicaid also have comorbid mental illnesses. Walkup et al. found that among persons in the New Jersey HIV/AIDS registry receiving Medicaid, 5.7% had a diagnosis of schizophrenia,19 much higher than the prevalence of schizophrenia in the general population, which is estimated to be about 1%.20 A clear weakness of this method is that HIV diagnoses identified in administrative records may not capture all HIV diagnoses and may not be linked to confirmed HIV-positive test results. An approach to measuring rates of HIV among individuals with SMI taken by investigators in Philadelphia, Pennsylvania, was to conduct HIV testing on remnant blood specimens collected from patients on 2 inpatient psychiatric units in the city. In this study, 10.1% of patients were found to be HIV-infected. Chart reviews up to the time of testing of the remnant blood failed to find documentation of previous HIV diagnosis in the clinical record for approximately one third of these persons. However, this study used a very specific sample that does not generalize to all patients seeking mental health services.16As the demographics of the HIV epidemic have shifted in the past decade, the degree to which HIV prevalence among persons with SMI has changed remains unclear. Accurate estimates of HIV prevalence among these persons and more information about access to and retention in care for HIV-positive persons with SMI is needed.The approval of rapid HIV testing by the US Food and Drug Administration and widespread availability of multiple rapid testing assays provides new opportunities for HIV testing and more efficient determination of prevalence estimates in hard-to-reach populations. Rapid HIV testing results can be obtained in approximately 20 minutes, allowing delivery of immediate posttest counseling and referral and linkage to HIV care. Prevention services for persons with preliminary positive test results can also reduce risks of transmission to others. The rapid turnaround for obtaining and delivering test results increases the flexibility of service delivery and might be useful for testing those with SMI within mental health settings. This is particularly important as the mental health system has been increasingly called upon to provide basic medical and preventive health services21–24 for those with SMI and is the most common place for where they receive care.25 Rapid testing thus holds great promise for integrating routine HIV testing into ongoing mental health services in a variety of clinical settings. The specificity of current US Food and Drug Administration–approved rapid HIV tests is high.26 Sensitivity for established infections is also high, but currently available rapid tests do not detect early infections that can be detected by laboratory tests.27Prevention services for HIV-positive patients in mental health centers have the potential to reduce risks of transmission to others. This is consistent with a positive prevention model proposed by Sikkema et al.28 although the empirical evidence to date has been mixed,29–31 with additional studies in progress.32 There is also an opportunity for rapid testing to facilitate linkage to infectious disease care for these individuals.33–36The purpose of this study was to use rapid HIV testing to estimate HIV prevalence and examine risk factors associated with HIV infection among people receiving treatment in the mental health system. We focused on 2 large urban communities (Philadelphia, PA, and Baltimore, MD) that have a high burden of HIV infection. By drawing the study sample from inpatient psychiatric units, outpatient community mental health centers (CMHCs), and outpatient intensive case management (ICM) programs, we captured patients served by the 3 predominant modalities of mental health service delivery in the United States.  相似文献

Objectives. We tested the efficacy of a sexual risk-reduction intervention for men in South Africa, where heterosexual exposure is the main mode of HIV transmission.Methods. Matched-pairs of neighborhoods in Eastern Cape Province, South Africa, were randomly selected and within pairs randomized to 1 of 2 interventions based on social cognitive theory and qualitative research: HIV/sexually transmitted infection (STI) risk-reduction, targeting condom use, or attention-matched control, targeting health issues unrelated to sexual risks. Sexually active men aged 18 to 45 years were eligible. The primary outcome was consistent condom use in the past 3 months.Results. Of 1181 participants, 1106 (93.6%) completed the 12-month follow-up. HIV and STI risk-reduction participants had higher odds of reporting consistent condom use (odds ratio [OR] = 1.32; 95% confidence interval [CI] = 1.03, 1.71) and condom use at last vaginal intercourse (OR = 1.40; 95% CI = 1.08, 1.82) than did attention-control participants, adjusting for baseline prevalence. No differences were observed on unprotected intercourse or multiple partnerships. Findings did not differ for sex with steady as opposed to casual partners.Conclusions. Behavioral interventions specifically targeting men can contribute to efforts to reduce sexual risk behaviors in South Africa.South Africa has more HIV cases than any other country, and like other sub-Saharan countries, has a predominantly heterosexual epidemic.1 In such an epidemic, men have an especially critical role to play: they are the ones who don male condoms, a particularly effective and available means of prevention, and thus control their use. They have, it has been argued, more power than women in relationships2–4 and are responsible for infecting women in many contexts, including forced intercourse and violence.3 Although calls for male responsibility in sexual behavior related to HIV and other sexually transmitted infections (STIs) have been made repeatedly,5–7 to our knowledge, only 1 study has evaluated an intervention created specifically for heterosexual men in South Africa.8 Men who received the gender-based-violence-and-HIV-risk-reduction intervention were more likely to report talking with a partner about condoms and using condoms consistently 1-month postintervention compared with men in an alcohol-and-HIV-risk-reduction control intervention.The present study evaluated an HIV/sexually transmitted infection (STI) risk-reduction intervention for South African men who have intercourse with women. We used a cluster-randomized design to reduce the potential for contamination between treatment arms that would be present if we were to randomize individuals. We randomized randomly selected neighborhoods (i.e., clusters) to a 3-session intervention based on social cognitive theory9 and extensive formative research10 and designed to reduce HIV/STI risk behavior or to a 3-session attention-control intervention designed to promote health by improving diet and physical activity. We hypothesized that the HIV/STI risk-reduction intervention would increase self-reported consistent condom use during vaginal intercourse in the postintervention period, the primary outcome, compared with the attention-control intervention, controlling for baseline condom use.  相似文献

Objectives. We examined correlates of condomless anal intercourse with nonmain sexual partners among African American men who have sex with men (MSM).Methods. We recruited social networks composed of 445 Black MSM from 2012 to 2014 in Milwaukee, Wisconsin; Cleveland, Ohio; and Miami Beach, Florida. Participants reported past-3-month sexual behavior, substance use, and background, psychosocial, and HIV-related characteristics.Results. Condomless anal intercourse outside main concordant partnerships, reported by 34.4% of MSM, was less likely in the case of no alcohol and marijuana use in the past 30 days, and higher risk-reduction behavioral intentions. High frequency of condomless anal intercourse acts with nonmain partners was associated with high gay community participation, weak risk-reduction intentions, safer sex not being perceived as a peer norm, low condom-use self-efficacy, and longer time since most recent HIV testing.Conclusions. Condomless anal intercourse with nonmain partners among Black MSM was primarily associated with gay community participation, alcohol and marijuana use, and risk-reduction behavioral intentions.HIV infection in the United States falls along sharp lines of disparity related to sexual orientation and race. Every year since HIV surveillance began, men who have sex with men (MSM) have accounted for the majority of the country’s HIV cases.1 The disease also disproportionately affects African Americans, who constitute 12% of the American population but carry 44% of its HIV infection burden.1 Yet, the starkest disparity emerges from the combined impact of race and sexual orientation. Black MSM represent only a fraction of a percent of the American population but accounted for more than 25% of the country’s new HIV infections in 2010,1 with HIV rates much higher among Black than White MSM.2 HIV incidence among racial-minority MSM in some cities ranges from 24% to 29%.3,4 Considerable attention is being given to biomedical strategies such as early initiation of antiretroviral therapy (ART) and preexposure ART prophylaxis for HIV prevention.5,6 However, the impact of these promising strategies will depend upon ART coverage and adherence, neither of which is likely to be quickly attained or complete. For this reason, integrated HIV prevention approaches are needed, including improved interventions to reduce risk behavior among racial-minority MSM.Previous research has examined but has generally failed to establish differences in individual-level risk practices between Black and White MSM.7–10 However, sexual network characteristics, high rates of undiagnosed and untreated HIV infection, high sexually transmitted infection (STI) prevalence, and unsuppressed viral load among HIV-positive African American MSM are believed to contribute to HIV disparities.9–16Black MSM are not a monolithic population,17–20 and multiple factors may influence extent of HIV vulnerability within the community of racial-minority MSM. These include risk-related sexual behavior norms, attitudes, and intentions21–25; substance use12,26–30; poverty and disadvantage19,20; and psychosocial domains including internalized homonegativity or homophobia,31–34 self-perceived masculinity,35,36 HIV conspiracy beliefs or mistrust,37,38 religiosity,39 and resilience.40,41 It is important to ascertain the relative importance of these and other factors to properly tailor HIV prevention interventions for racial-minority MSM.In this study, we recruited social networks of African American MSM and sought to determine the relationships of 4 types of factors with the riskiness of men’s sexual behavior practices: (1) social, economic, and demographic background characteristics; (2) substance use; (3) HIV risk–specific knowledge, attitudes, beliefs, and intentions; and (4) psychosocial domains including internalized homonegativity, self-ascribed masculinity, AIDS conspiracy beliefs, resilience, religiosity, and gay community participation. We examined HIV risk–specific characteristics because they are proximal to adopting protective actions according to many behavioral science theories.42–44 We examined psychosocial domains because broader personal and contextual life experiences may also potentiate risk. We sought to identify characteristics related not only to some men’s high-risk behavior but also the adoption of very safe behavior by other African American MSM, a strengths-based question that has been insufficiently explored.  相似文献

The HIV epidemic is an ongoing public health problem fueled, in part, by undertesting for HIV. When HIV-infected people learn their status, many of them decrease risky behaviors and begin therapy to decrease viral load, both of which prevent ongoing spread of HIV in the community.Some physicians face barriers to testing their patients for HIV and would rather their patients ask them for the HIV test. A campaign prompting patients to ask their physicians about HIV testing could increase testing.A mobile health (mHealth) campaign would be a low-cost, accessible solution to activate patients to take greater control of their health, especially populations at risk for HIV. This campaign could achieve Healthy People 2020 objectives: improve patient–physician communication, improve HIV testing, and increase use of mHealth.World AIDS Day each December reminds us of the ongoing HIV epidemic in the United States and its disproportionate toll on racial and ethnic minority communities. HIV testing is an essential strategy to curb the ongoing epidemic. When people infected with HIV learn their status, many of them decrease risky behaviors to prevent spread to others1 and begin antiretroviral therapy to decrease viral load, the main biological predictor of the ongoing spread of HIV in the community.2 Despite national recommendations to make HIV testing routine for all adults,3–6 HIV testing rates—particularly among the racial and ethnic communities hardest hit—remain low.7 Patients want to be tested.8 However, physicians face numerous HIV testing barriers, including physician discomfort with initiating HIV testing discussions,9 physicians not realizing that patients expect HIV testing to be done,8 time,10,11 and competing clinical priorities.11,12A pioneering intervention to improve HIV testing in health care settings may be a patient-initiated approach. The push–pull capacity model offers a framework to guide a solution to improve patient-initiated HIV testing.13,14 With a push–pull model, health information can be provided—or pushed—to many patients. This push creates a demand—or pull—for health services that address patient concerns. The ubiquity of cell phones and the pervasive use of text messaging provide an innovative platform for promoting an effective HIV testing campaign. Operationalizing the push–pull model through mobile health (mHealth) could be a novel approach to improving HIV testing in health care settings. This initiative would reduce demands on physicians, increase patients’ engagement in their own health, and address a significant ongoing public health problem.15 Goals of Healthy People 2020 include eliminating health disparities and increasing the number of people who have been tested for HIV.16  相似文献

Objectives. We evaluated the efficacy of a mobile medical clinic (MMC) screening program for detecting latent tuberculosis infection (LTBI) and active tuberculosis.Methods. A LTBI screening program in a MMC in New Haven, Connecticut, used medical surveys to examine risk factors and tuberculin skin test (TST) screening eligibility. We assessed clinically relevant correlates of total (prevalent; n = 4650) and newly diagnosed (incident; n = 4159) LTBI from 2003 to 2011.Results. Among 8322 individuals, 4159 (55.6%) met TST screening eligibility criteria, of which 1325 (31.9%) had TST assessed. Similar to LTBI prevalence (16.8%; 779 of 4650), newly diagnosed LTBI (25.6%; 339 of 1325) was independently correlated with being foreign-born (adjusted odds ratio [AOR] = 8.49; 95% confidence interval [CI] = 5.54, 13.02), Hispanic (AOR = 3.12; 95% CI = 1.88, 5.20), Black (AOR = 2.16; 95% CI = 1.31, 3.55), employed (AOR = 1.61; 95% CI = 1.14, 2.28), and of increased age (AOR = 1.04; 95% CI = 1.02, 1.05). Unstable housing (AOR = 4.95; 95% CI = 3.43, 7.14) and marijuana use (AOR = 1.57; 95% CI = 1.05, 2.37) were significantly correlated with incident LTBI, and being male, heroin use, interpersonal violence, employment, not having health insurance, and not completing high school were significantly correlated with prevalent LTBI.Conclusions. Screening for TST in MMCs successfully identifies high-risk foreign-born, Hispanic, working, and uninsured populations and innovatively identifies LTBI in urban settings.Foreign-born populations are at greatest risk for having both latent tuberculosis infection (LTBI) and developing tuberculosis (TB) disease within high-income countries and, in 2012, accounted for 63.0% of the 9951 TB cases in the United States.1 Newly diagnosed and reactivated TB infection among foreign-born individuals in the United States is currently 12 times greater (15.8 vs 1.4 cases per 100 000 population) than among US-born persons.1 Among foreign-born individuals, LTBI often reactivates within 5 to 10 years after arrival to the United States.2,3 Undocumented migrants and visitors from high-TB-prevalence countries, however, do not undergo routine LTBI screening and thus remain outside traditional health care screening and treatment programs in primary or specialty care settings except when they are acutely ill.3,4 Thus, identifying and treating LTBI cases among these high-risk populations before transforming to TB disease and resultant transmission to others is crucial to ending the cycle of ongoing TB infection within the United States.Workplace screening,4,5 mandatory criminal justice system screening,6–8 screening for entry into medication-assisted therapy and drug treatment programs,9 and refugee and naturalization programs10,11 have been successful for reaching legal and domestic populations, but innovative options are needed to target foreign-born populations that are not yet integrated into mainstream care.Culturally and geographically isolated foreign-born groups may be overlooked especially if there is low self-perception of tuberculosis risk.12 Tuberculin skin testing (TST), though imperfect, is internationally recognized and has been shown to be a reasonably accurate assessment of LTBI status in immunocompetent adults, despite receiving previous Bacillus Calmette-Guérin vaccine.13 Whereas other studies have focused on traditional clinics or statewide programs,14 we present an innovative mobile medical clinic (MMC) as a model to target “hidden” foreign-born populations for LTBI screening.New Haven, Connecticut, the country’s fourth poorest city for its size, with a census of 130 000, is a medium-sized urban setting in New England that has experienced extraordinary social and medical disparities including a high prevalence of poverty, drug addiction, HIV/AIDS, and unemployment and is disproportionately comprised of people of color, including 35.4% and 27.4% being Black or Hispanic, respectively.15 As New Haven is an industrial city with low-paying jobs, there has been an influx of foreign-born people, now officially comprising 11.6% of the population, with many having an undocumented residency status. Health care access for this group is absent unless individuals pay directly for fee-for-service, and concern for deportation and arrest further hinders willingness to seek care.16The Community Health Care Van (CHCV) is an MMC that provides free health care 5 days per week in 4 impoverished neighborhoods in New Haven. Though at inception the program was linked to the needle and syringe exchange program,17 it has since expanded over 20 years to become a vital bridge to a diverse array of health and addiction treatment services that includes services for medically underserved populations, including directly administered antiretroviral therapy to treat HIV,18–21 buprenorphine maintenance therapy,22–25 community transitional programs from the criminal justice system,26–33 hepatitis B vaccination,34 rapid hepatitis C screening,35 and other ongoing primary health care programs such as screening and monitoring of sexually transmitted infections,36 diabetes, and hypertension. In addition, the CHCV provides outreach and intensive case management services.37 Screening for LTBI and TB disease began in 2003 to target high-risk undocumented and foreign-born clients, as well as clients entering drug treatment programs or homeless shelters, who were concerned about TB infection yet were reluctant to seek care in traditional health care settings for fear of deportation, prohibitive cost, or language barriers. The LTBI screening program shortly thereafter became successfully incorporated into the country’s first mobile buprenorphine maintenance therapy program.9  相似文献

Objectives. We examined the association between individual and clustered lifestyle behaviors in middle age and later in cognitive functioning.Methods. Middle-aged participants (n = 2430) in the Supplémentation en Vitamines et Minéraux Antioxydant study self-reported their low physical activity, sedentary behavior, alcohol use, smoking, low fruit and vegetable consumption, and low fish consumption. We assessed cognition 13 years later via 6 neuropsychological tests. After standardization, we summed the scores for a composite cognitive measure. We estimated executive functioning and verbal memory scores using principal component analysis. We estimated the mean differences (95% confidence intervals [CIs]) in cognitive performance by the number of unhealthy behaviors using analysis of covariance. We identified latent unhealthy behavior factor via structural equation modeling.Results. Global cognitive function and verbal memory were linearly, negatively associated with the number of unhealthy behaviors: adjusted mean differences = −0.36 (95% CI = −0.69, −0.03) and −0.46 (95% CI = −0.80, −0.11), respectively, per unit increase in the number of unhealthy behaviors. The latent unhealthy behavior factor with low fruit and vegetable consumption and low physical activity as main contributors was associated with reduced verbal memory (RMSEA = 0.02; CFI = 0.96; P = .004). No association was found with executive functioning.Conclusions. Comprehensive public health strategies promoting healthy lifestyles might help deter cognitive aging.Noncommunicable diseases with notable lifestyle components are the leading causes of death worldwide.1,2 There is also growing evidence of the critical role of different midlife health and risk behaviors in cognitive aging.3–7 Because lifestyles are inherently modifiable and no treatment of cognitive decline is available, such findings argue for the paramount importance of prevention.8,9Current data support a deleterious effect of alcohol abstinence or abuse (compared with moderate alcohol consumption),10 smoking,7 low fruit and vegetable intake,11 low fish intake,12 and low physical activity (PA) levels13 on cognitive aging. However, it has been widely documented that lifestyle factors are strongly correlated with each other, forming a cluster of healthy or unhealthy behaviors.14 Traditionally, such interrelations have been accounted for by statistical adjustment; however, it is of major public health interest to consider the cumulative and combined effect of the various lifestyle behaviors on health by using multidimensional strategies.14Research that examines the combined effect of lifestyle factors on mortality is plentiful, and data have been colligated in a recent meta-analysis.15 These authors reported a 66% reduction in mortality risk by comparing adherence to 4 or more healthy lifestyle behaviors versus engagement in any number of unhealthy behaviors.The combined effect of lifestyle factors has also been explored in relation to cardiovascular diseases,16–18 cancer,18–22 diabetes,18,23 memory complaints,24 and dementia25–27; however, very few studies have reported findings regarding cognition.28,29 Despite heterogeneity in the definition of a healthy lifestyle, study design, and residual confounding, available, but scarce, data support a critical, protective role of healthy lifestyles in cognitive health through their beneficial properties via oxidative, inflammatory, vascular, and other neuroprotective pathways.30–33Our objectives in this study were to examine the association between individual and clustered lifestyle behaviors and later cognitive functioning. We employed traditional and innovative techniques (structural equation modeling) in our epidemiological pursuit.  相似文献
