Sexual risk taking and the HIV care continuum in an online sample of men who have sex with men

Antiretroviral Therapy (ART) suppresses HIV replication, reducing the risk of transmission. However, many people living with HIV in the US are not virally suppressed even after diagnosis and initiating ART, and may become disengaged from care at each stage of the HIV care continuum (HCC). In the current study we assessed the sexual risk behaviors of MSM by HCC stage. US MSM who completed an online survey (N?=?12,995) in 2015 were categorized into 6 HCC groups. Mean age was 39.2 and a majority identified as White (49.6%). At every stage of the HCC, we found higher proportions of individuals engaged in care compared to CDC estimates. A majority of the sample was HIV-positive and engaged in care, with 67.2% of HIV-positive participants reporting viral suppression with ART. Across HCC groups, participants reported high rates of past 6-month condomless anal sex (CAS) (79.2%–84.8%) and CAS with serodiscordant or unknown status partners (38.0%–84.1%). Notably, MSM with unknown HIV serostatus reported the highest proportion of CAS and serodiscordant CAS. HIV-positive MSM not on ART were more likely to report an STI diagnosis (p?p?p?相似文献   

Correlates of viral suppression among HIV-infected men who have sex with men and transgender women in Lima,Peru

In Peru, HIV is concentrated among men who have sex with men (MSM) and transgender women (TGW). Between June 2015 and August 2016, 591 HIV-positive MSM and TGW were recruited at five clinical care sites in Lima, Peru. We found that 82.4% of the participants had achieved viral suppression (VS; VL?相似文献   

Delayed entry into HIV medical care in a nationally representative sample of HIV-infected adults receiving medical care in the USA

Before widespread antiretroviral therapy (ART), an estimated 17% of people delayed HIV care. We report national estimates of the prevalence and factors associated with delayed care entry in the contemporary ART era. We used Medical Monitoring Project data collected from June 2009 through May 2011 for 1425 persons diagnosed with HIV from May 2004 to April 2009 who initiated care within 12 months. We defined delayed care as entry >three months from diagnosis. Adjusted prevalence ratios (aPRs) were calculated to identify risk factors associated with delayed care. In this nationally representative sample of HIV-infected adults receiving medical care, 7.0% (95% confidence interval [CI]: 5.3–8.8) delayed care after diagnosis. Black race was associated with a lower likelihood of delay than white race (aPR 0.38). Men who have sex with women versus women who have sex with men (aPR 1.86) and persons required to take an HIV test versus recommended by a provider (aPR 2.52) were more likely to delay. Among those who delayed 48% reported a personal factor as the primary reason. Among persons initially diagnosed with HIV (non-AIDS), those who delayed care were twice as likely (aPR 2.08) to develop AIDS as of May 2011. Compared to the pre-ART era, there was a nearly 60% reduction in delayed care entry. Although relatively few HIV patients delayed care entry, certain groups may have an increased risk. Focus on linkage to care among persons who are required to take an HIV test may further reduce delayed care entry.     

Multiple Dimensions of Stigma and Health Related Factors Among Young Black Men Who Have Sex with Men

This study is among the first to examine the association between multiple domains of HIV-related stigma and health-related correlates including viral load and medication adherence among young Black men who have sex with men (N = 92). Individual logistic regressions were done to examine the hypothesized relationships between HIV-related stigma and various health and psychosocial outcomes. In addition to examining total stigma, we also examined four domains of HIV stigma. Findings revealed the various domains of stigma had differential effects on health-related outcomes. Individuals who reported higher levels of total stigma and personalized stigma were less likely to be virally suppressed (OR 0.96, 95 % CI 0.91–1.00 and OR 0.50, 95 % CI 0.25–1.02, respectively). Concerns about public attitudes toward HIV were positively related to medication adherence (OR 2.18, 95 % CI 1.20–3.94) and psychological distress (OR 5.02, 95 % CI 1.54–16.34). The various domains of HIV stigma differentially affected health and psychosocial outcomes, and our findings suggest that some forms of HIV stigma may significantly affect viral load and medication adherence among this population. Stigma-informed approaches to care and treatment are needed, along with incorporated psychological and social supports.     

Long term engagement in HIV care among postpartum women with perinatal HIV infection in the United States

Despite growing literature on pregnancy in women with perinatally-acquired HIV infection (PHIV), little is known regarding HIV and reproductive health outcomes postpartum. We describe pregnancy, reproductive, and HIV care outcomes for 2 years postpartum among pregnant women with PHIV who delivered in a large urban health system in Atlanta, Georgia, USA from 2011–2016. We reviewed medical records of women with PHIV to estimate retention in HIV care (two HIV care visits or viral load measurements >90 days apart) and viral suppression (<200 copies/mL) at 12 and 24 months postpartum. Among 22 pregnant women with PHIV, 13 (59%) had a CD4 count of less than 300 cells/mm³ at the time of antenatal care entry; most (n = 13, 59%) women achieved viral suppression at time of delivery. Three quarters of women attended a postpartum HIV primary care visit, within an average of 193 (range 17–727) days. Only 4 (20%) women were retained and 3 (15%) virally suppressed at 12 postpartum, and 2 (12%) were retained and none virally suppressed at 24 months. Despite the unique challenges they face, multidisciplinary efforts are needed to engage women with PHIV during pregnancy and facilitate the transition to sustained HIV primary care in the postpartum period.     

Characterizing the HIV Prevention and Care Continua in a Sample of Transgender Youth in the U.S.

In the U.S., transgender and other gender minority (TG) youth are an at-risk group understudied in HIV prevention and treatment. This study sought to characterize the HIV prevention and care continua in a diverse sample of 181 sexually-active TG ages 16–24 years (mean age = 20.7 years; 76.8% trans feminine; 69.1% youth of color) recruited July–December 2015 in 14 U.S. cities. Overall, 30.9% reported living with HIV, of which 71.4% were on antiretroviral therapy (ART) and 55.0% were medication adherent; 65.6% were known to be virally suppressed. In multivariable models, medical gender affirmation was associated with lower odds of viral suppression. Medical gender affirmation and stigma in HIV care were each independently associated with elevated odds of having missed HIV care appointments. Among at-risk TG youth not living with HIV, only 8.2% had accessed pre-exposure prophylaxis (PrEP). Early biobehavioral prevention and treatment interventions are needed for TG youth.     

Examining the relationship between psychological distress and adherence to anti-retroviral therapy among Ugandan adolescents living with HIV

Psychological distress is common among adolescents living with HIV (ALHIV) worldwide, and has been associated with non-adherence to anti-retroviral therapy (ART), leading to poor virologic suppression, drug resistance, and increased risk for AIDS morbidity and mortality. However, only a few studies have explored the relationship between psychological distress and ART adherence among adolescents in sub-Saharan Africa. The paper examines the relationship between psychological distress and ART adherence, and effect of psychosocial resources on ART adherence. We conducted a cross-sectional survey of 464 ALHIV (aged 12–19; 53% female) seeking HIV care at a large HIV treatment center in Kampala, Uganda. ALHIV were recruited during routine clinic visits. Three self-reported binary adherence measures were utilized: missed pills in the past three days, non-adherence to the prescribed medical regimen, and self-rated adherence assessed using a visual analog scale. Psychological distress was measured as a continuous variable, and computed as the mean score on a locally developed and validated 25-item symptom checklist for Ugandan ALHIV. Psychosocial resources included spirituality, religiosity, optimism, social support, and coping strategies. After adjusting for respondents’ socio-demographic characteristics and psychosocial resources, a unit increase in psychological distress was associated with increased odds of missing pills in past 3 days (Odds Ratio(OR)?=?1.75; Confidence Interval (CI): 1.04–2.95), not following the prescribed regimen (OR?=?1.63; CI: 1.08–2.46), and lower self-rated adherence (OR?=?1.79; CI: 1.19–2.69). Psychosocial resources were associated with lower odds for non-adherence on all three self-report measures. There is a need to strengthen the psychosocial aspects of adolescent HIV care by developing interventions to identify and prevent psychological distress among Ugandan ALHIV.     

Treatment Outcomes Associated with Quitting Cigarettes Among Sexual Minority Men Living with HIV: Antiretroviral Adherence,Engagement in Care,and Sustained HIV RNA Suppression

Cigarette smoking is particularly harmful for sexual minority men living with HIV. This study aimed to find benefits of quitting by examining relationships between smoking and sustained HIV RNA suppression, recent CD4 count, ART medication adherence, and engagement in HIV medical care. Sexual minority men (n?=?346), former or current smokers, received HIV care at a community health center. Survey responses were combined with electronic health record data in adjusted regression models. Most patients were Caucasian (87%) and 148 (46%) had incomes below the poverty level and 80% had sustained HIV RNA suppression. Compared to current smokers, former smokers had increased odds of sustaining HIV RNA suppression (OR 1.89; 95% CI 1.02–3.48) of reporting?>?90% adherence (OR 2.25; 95% CI 1.21–4.17), and were less likely to miss appointments (OR 0.37; 95% CI 0.17–0.82). Heavier smokers (OR 0.36; 95% CI 0.17–0.77) and patients who smoked the longest (OR 0.31; 95% CI 0.14–0.68) had reduced odds of sustaining HIV RNA suppression. Smoking assessment, treatment, and referral could augment HIV outcomes for sexual minority men with HIV.     

The relationship between adverse neighborhood socioeconomic context and HIV continuum of care outcomes in a diverse HIV clinic cohort in the Southern United States

Retention in care and viral suppression are critical to delaying HIV progression and reducing transmission. Neighborhood socioeconomic context (NSEC) may affect HIV care receipt. We therefore assessed NSEC’s impact on retention and viral suppression in a diverse HIV clinical cohort.

HIV-positive adults with ≥1 visit at the Vanderbilt Comprehensive Care Clinic and 5-digit ZIP code tabulation area (ZCTA) information between 2008 and 2012 contributed. NSEC z-score indices used neighborhood-level socioeconomic indicators for poverty, education, labor-force participation, proportion of males, median age, and proportion of residents of black race by ZCTA. Retention was defined as ≥2 HIV care visits per calendar year, >90 days apart. Viral suppression was defined as an HIV-1 RNA <200 copies/mL at last measurement per calendar year. Modified Poisson regression was used to estimate risk ratios (RR) and 95% confidence intervals (CI).

Among 2272 and 2541 adults included for retention and viral suppression analyses, respectively, median age and CD4 count at enrollment were approximately 38 (1st and 3rd quartile: 30, 44) years and 351 (176, 540) cells/μL, respectively, while 24% were female, and 39% were black. Across 243 ZCTAs, median NSEC z-score was 0.09 (-0.66, 0.48). Overall, 79% of person-time contributed was retained and 74% was virally suppressed. In adjusted models, NSEC was not associated with retention, though being in the 4th vs. 1st NSEC quartile was associated with lack of viral suppression (RR?=?0.88; 95% CI: 0.80–0.97).

Residing in the most adverse NSEC was associated with lack of viral suppression. Future studies are needed to confirm this finding.     

Place-based predictors of HIV viral suppression and durable suppression among heterosexuals in New York city

Scant research has explored place-based correlates of achieving and maintaining HIV viral load suppression among heterosexuals living with HIV. We conducted multilevel analyses to examine associations between United Hospital Fund (UHF)-level characteristics and individual-level viral suppression and durable viral suppression among individuals with newly diagnosed HIV in New York City (NYC) who have heterosexual HIV transmission risk. Individual-level independent and dependent variables came from NYC’s HIV surveillance registry for individuals diagnosed with HIV in 2009–2013 (N?=?3,159; 57% virally suppressed; 36% durably virally suppressed). UHF-level covariates included measures of food distress, demographic composition, neighborhood disadvantage and affluence, healthcare access, alcohol outlet density, residential vacancy, and police stop and frisk rates. We found that living in neighborhoods where a larger percent of residents were food distressed was associated with not maintaining viral suppression. If future research should confirm this is a causal association, community-level interventions targeting food distress may improve the health of people living with HIV and reduce the risk of forward transmission.     

Mindfulness,Mental Health and HIV Outcomes Among Female Sex Workers in the Dominican Republic and Tanzania

We examined the relationship between mindfulness, mental health and HIV outcomes among female sex workers (FSW) from the Dominican Republic (DR) (n?=?201) and Tanzania (n?=?208) using cross-sectional survey and biologic data. We employed stratified multivariate linear and logistic regression. Depression was associated with lower odds of ART adherence in the DR (AOR 0.25, 95% CI: 0.08–0.78) and of viral suppression in Tanzania (AOR 0.49, 95% CI: 0.24–0.97). In both countries, mindfulness was associated with lower odds of moderate to severe depression (AOR 0.82, 95% CI: 0.76–0.88 for the DR; AOR 0.85, 95% CI: 0.77–0.95 for Tanzania). In the DR, mindfulness was associated with lower odds of anxiety (AOR 0.83, 95% CI: 0.77–0.89), lower HIV stigma (β?=?? 0.28 per unit change, 95% CI: ? 0.37 to ? 0.19) and greater odds of viral suppression (AOR 1.09, 95% CI: 1.02–1.15). Findings demonstrate the potential of tailored mindfulness interventions to improve mental health and HIV outcomes among FSW.

     

Social and structural determinants of HIV treatment and care among black women living with HIV infection: a systematic review: 2005–2016

Black/African American (black) women comprised 59% of women living with HIV at the end of 2014 and 61% of HIV diagnoses among women in 2015. Black women living with HIV infection (BWLH) have poorer health outcomes compared with women of other races/ethnicities; social and structural determinants are often cited as barriers and facilitators of care. The objective of this qualitative review was to identify social and structural barriers and facilitators of HIV treatment and care among BWLH. The systematic review was conducted in six-stages using databases such as PubMed, PsycINFO, and Google Scholar: 1) searched for studies that enrolled BWLH published between January 2005 and December 2016, 2) excluded unpublished reports and commentaries, 3) limited the search to our primary keywords, 4) limited our search to studies that included participants living with HIV infection that were >60% black and 100% female, 5) extracted and summarized the data, and 6) conducted a contextual review to identify common themes. Of 534 studies retrieved, 16 were included in the final review. Studies focused on: ART medication adherence (n?=?5), engagement/retention in care (n?=?4), HIV care and treatment services (n?=?3), viral suppression (n?=?1), and addressing multiple HIV care outcomes (n?=?3). Main barrier themes included lack of family and/or social support, poor quality HIV services, and HIV-related stigma, particularly from healthcare providers; facilitator themes included resilience, positive relationships between case management and support services, high racial consciousness, and addressing mental health. Interventions that decrease these noted barriers and strengthen facilitators may help improve care outcomes for BWLH. Also, more HIV stigma-reduction training for healthcare providers may be warranted.     

Correlates of Engagement in HIV Care Among Transgender Women of Color in the United States of America

HIV prevalence among transgender women of color (TWC) in the United States of America is high. We enrolled TWC living with HIV (N = 858) to evaluate 1nine HIV care interventions. We examined factors associated with four outcomes at enrollment: linkage to care, ever being on antiretroviral treatment, retention in care and viral suppression. The sample was 49% Hispanic/Latino, 42% Black; average age was 37 years; 77% were ever linked to care, 36% were ever on treatment, 22% were retained in care, and 36% were virally suppressed. Current hormone use was significantly associated with linkage, retention, and viral suppression (all aORs > 1.5), providing evidence for gender-affirming care as an important facilitator of engagement in HIV care. Greater health care empowerment was significantly associated with greater odds of all outcomes (aORs between 1.19 and 1.37). These findings identify potential intervention targets to improve the provision of care and treatment for TWC living with HIV.

     

Improved long-term antiretroviral treatment outcomes amongst patients receiving community-based adherence support in South Africa

Retaining high levels of patients in care who are virally suppressed over long treatment periods has been an important challenge for antiretroviral treatment (ART) programmes in sub-Saharan Africa, the region having the highest HIV burden globally. Clinic-linked community-based adherence support (CBAS) programmes provide home-based adherence and psychosocial support for ART patients. However, there is little evidence of their longer-term impact. This study assessed the effectiveness of CBAS after eight years of ART. CBAS workers are lay healthcare personnel providing regular adherence and psychosocial support for ART patients and their households through home visits addressing household challenges affecting adherence. A multicentre cohort study using routinely collected data was undertaken at six public ART sites in a high HIV-prevalence South African district. Patient retention, loss to follow-up (LTFU), viral suppression and CD4 cell restoration were compared between patients with and without CBAS, using competing-risks regression, linear mixed models and log-binomial regression. 3861 patients were included, of whom 1616 (41.9%) received CBAS. Over 14,792 patient-years of observation, the cumulative incidence of LTFU was 37.3% and 46.2% amongst patients with and without CBAS, respectively, following 8 years of ART; adjusted subhazard ratio (CBAS vs. no CBAS)?=?0.74 (95% CI: 0.66–0.84; P?P?=?.015). Annual CD4 cell increases from baseline were 62.8 cells/µL/year and 51.5 cells/µL/year amongst patients with and without CBAS, respectively, after 6.5 years or more (P?=?.034). After adjustment, annual CD4 cell recovery was 15.1 cells/µL/year (95% CI: 2.7–27.6) greater in CBAS patients (P?=?.017). ART patients who received CBAS had improved long-term patient retention, viral suppression and immunological restoration. CBAS is an intervention that can improve longer-term ART programme outcomes in resource-limited settings.     

Identifying patterns of retention in care and viral suppression using latent class analysis among women living with HIV in Florida 2015–2017

ABSTRACT

The study objective was to classify women with newly diagnosed HIV into patterns of retention in care (≥2 HIV care visits ≥3 months apart) and viral suppression over time and identify factors associated with class membership. Florida HIV/AIDS surveillance data were used to conduct Latent Class Analysis to classify women into patterns, and multinomial regression was used to compare the prevalence of class membership by demographic and clinical factors. Four classes were selected based on model fit parameters: (Class 1) consistently retained and suppressed (>90% probability of being retained and suppressed), (Class 2) not consistently retained or suppressed (≤10% probability of being retained and suppressed), (Class 3) increasingly retained and suppressed, and (Class 4) decreasingly retained and suppressed. The proportion of women in each class was 48.6%, 24.9%, 14.3%, and 12.2%, respectively. Women aged 25–34 compared to 35–49 years old, injection drug use mode of exposure, US born, and not linked to care three months post-diagnosis had a lower prevalence of belonging to the consistently retained and suppressed class. Findings may be useful in tailoring and targeting interventions to increase the prevalence of women who are consistently retained in care and virally suppressed.     

Reproductive health counseling delivered to women living with HIV in the United States

Advances in antiretroviral therapy (ART) and reproductive technologies have made transmission of HIV to partners and infants almost completely preventable. Comprehensive reproductive health counseling (CRHC) is an important component of care for women living with HIV, but few women report discussing reproductive health with an HIV care provider. We surveyed a probability sample of U.S. HIV care providers during 2013–2014. Of 2023 eligible providers, 1234 responded (64% adjusted provider response rate). We estimated the percentage delivering CRHC to their female patients. CRHC was defined as delivering each of five components of reproductive health care to most or all female patients. We assessed associations between provider characteristics and delivering CRHC using chi-squared tests and multivariable logistic regression. Of all providers, 49% (95% confidence interval [CI], 42–55) reported delivering all components of CRHC: 71% assessed reproductive intentions of reproductive-aged women, 78% explained perinatal transmission risk, 87% discussed ART for preventing perinatal transmission, 76% provided contraception as appropriate, and 64% provided referrals for preconception care. Among providers who offered primary care (83% of sample), 52% (CI: 44–60) delivered CRHC compared to 33% (CI: 22–44) of providers who did not offer primary care (P?=?.01). More female providers (46% of sample) compared to male providers delivered CRHC (57% [CI: 48–65] vs. 40% [CI: 31–50], P?相似文献   

Sex Trade and Health Care Utilization Among People Living with HIV/AIDS

People living with HIV/AIDS (PLWH) are more likely to have a history of trading sex, but little research has examined whether trading sex is associated with lower health care utilization amongst PLWH. This study assesses this association with PLWH (N?=?583) recruited and surveyed from seven community sites in six US cities participating in a multi-site community-based HIV test and treat initiative. Participants were 90.6% Black or Latino, 30.4% homeless, and 9.0% (1 in 11) sold sex (past 90 days). Most reported receiving HIV clinical care (63.9%, past 6 months) and HIV case management (68.9%, past year), but 35.7% reported a missed health care appointment (past 3 months). In adjusted regression models, trading sex was associated with a missed health care appointment (OR?=?2.44) and receiving psychological assistance (OR?=?2.31), past 90 days, but not receipt of HIV care or supportive HIV services. Trading sex may compromise consistent health care utilization among PLWH.     

Text Messaging Improves HIV Care Continuum Outcomes Among Young Adult Trans Women Living with HIV: Text Me,Girl!

Young adult trans women living with HIV in the US exhibit suboptimal advancement through the HIV Care Continuum relative to national averages. From December 2016 through May 2018, 134 young adult trans women living with HIV enrolled in Text Me, Girl!, a theory-based, trans-specific text-messaging intervention designed to improve HIV Care Continuum outcomes. Participants (N?=?130) averaged 29.5 years, were predominantly Latinx (43%) or African American/Black (40%). Clustered logistic and ordinal logistic multivariable models (n?=?105; 366 observations) indicate that through 18-month follow-up, increased exposure to the text-messaging intervention was associated with significant (p?<?0.05) increased retention to HIV care (adjusted odds ratio [aOR] 1.33) and biomarker-confirmed viral suppression (aOR 1.51); retention in the intervention was associated with significantly increased likelihood of ART uptake (aOR 2.95) and “excellent” ART adherence (aOR 10.44). Text Me, Girl! offers promising evidence that a unidirectional, automated text-messaging intervention can improve HIV care outcomes among young adult trans women living with HIV.
