Women in prison have a higher prevalence of HIV than men. After release from prison, former inmates have the opportunity to engage in risk behaviors for HIV and other sexually transmitted infections (STIs). We sought to assess change in risk behaviors over time and the association of gender with risk behavior in the postrelease period. In this prospective cohort study, we interviewed 200 former inmates (51 women) approximately two weeks (baseline) and three months (follow-up) after release and tested them for HIV infection at follow-up. We examined the association of gender with unprotected vaginal or anal sex in the last seven days using chi-square and Fisher's exact tests and multivariable logistic regression. At baseline, 22% of men and 41% of women reported unprotected vaginal sex (p < 0.01) and 5% of men and 8% of women reported unprotected anal sex (p = 0.51). Being younger (OR for each decade increase 0.48, 95% CI = 0.29–0.80), being gay/lesbian or being bisexual (compared with being heterosexual, OR = 4.74, 95% CI = 1.01–22.17 and OR = 3.98, 95% CI = 1.41–11.26, respectively), or reporting a drug of choice of heroin/speedballs or cocaine/crack (compared with marijuana/no drug of choice, OR = 24.00, 95% CI = 5.15–111.81 and OR = 3.49, 95% CI = 1.20–10.18, respectively) was associated with unprotected vaginal or anal sex after adjusting for race, homelessness, and hazardous drinking. At follow-up, 21% of men and 44% of women reported unprotected sex (p = 0.005), and female gender (OR = 4.42, 95% CI = 1.79–10.94) and hazardous drinking (compared with not meeting criteria for hazardous drinking, OR = 3.64, 95% CI = 1.34–9.86) were associated with unprotected sex, adjusting for race and homelessness. In this population with a high prevalence of HIV, we demonstrated persistent engagement in sexual risk behavior during the postrelease period. Enhanced efforts to promote sexual health and reduced risk behavior among both male and female current and former prison inmates are needed, including improved access to preventive care and HIV and STI screening, testing, and treatment.  相似文献

In a cross-sectional study in 1998 we assessed human immunodeficiency virus (HIV) and syphilis infections and their risk factors among the 316 registered female sex workers (FSWs) of Toliary, south-west Madagascar. No case of HIV infection was detected, but 18.4% of registered FSWs had syphilis. Only half of these women regularly used condoms. In a multiple logistic regression analysis, risk factors for syphilis infection were multiple clients per week and, paradoxically, regular use of condoms. The variables associated with irregular use of condoms were younger ages of registered FSWs, multiple clients per week and Malagasy clients. The high prevalence of syphilis infection associated with irregular use of condoms might facilitate a very fast spread of HIV infection among these FSWs. Promotion of condom use and surveillance of sexually transmitted infections and HIV infection incidence are needed in the south of Madagascar.  相似文献

AIMS: To characterize heroin and cocaine users in New York City who have changed from injection to non-injection drug administration and to identify factors associated with long-term non-injection use. DESIGN: Two cross-sectional studies of heroin and cocaine users in New York City. SETTINGS AND PARTICIPANTS: New admissions were recruited at drug abuse treatment programs (2000-04) and respondent-driven sampling was used to recruit drug users from the community (2004). Both injecting and non-injecting drug users participated in each study. 'Former injectors' were defined operationally as people who had used heroin and/or cocaine in the 6 months prior to the interview and who had injected illicit drugs in the past, but whose most recent injection was more than 6 months before the study interview. 'Current' injectors were defined as people who had injected heroin and/or cocaine in the 6 months prior to the interview. MEASUREMENTS: A structured interview on drug use history was administered, and a serum sample was collected and tested for the human immunodeficiency virus (HIV). FINDINGS: A total of 104 former injectors was recruited for the drug abuse treatment program study, and 229 current injectors were recruited for the community recruitment study; 160 former injectors and 1731 current injectors were recruited from the drug abuse treatment study. Compared with the current injectors, former injectors were older and more likely to be African American. The former injectors reported long intervals since their most recent injection, a mean of 8 years in the drug abuse treatment program study and a mean of 12 years in the community recruitment study. The most common reasons for stopping injection drug use included concerns about health, social stigmatization and self-image, and preference for intranasal use as a route of drug administration. The results were highly consistent across the two studies. CONCLUSIONS: The transition from injection to non-injection use appears to be relatively stable behavior change for many former injectors, who report a decade or more without injecting. Developing a greater understanding of the transition from injection to stable non-injection drug use may provide insights into the natural histories of drug use and addiction.  相似文献

The study aimed to assess the association between male circumcision and HIV infection and STDs. The issue is controversial as various studies reported conflicting findings. A cross-sectional comparative study based on the secondary data of 18 Demographic Health Surveys (DHS), carried out in Sub-Saharan Africa starting from 2003, was conducted. From all surveys, information on 70 554 males aged 15 – 59 years was extracted. The association between male circumcision and HIV infection and STD symptoms (genital discharge or genital ulcer/sore) was assessed using binary logistic regression. Adjustment was made for sexual history and basic socio-demographic variables. The weighted prevalence of HIV among men 15 – 59 years was 3.1%. In the bivariate analysis uncircumcised status was significantly associated with risk of HIV, with odds ratio (OR) of 4.12 (95% CI: 3.85 – 4.42). The association was even more significant (4.95 (95% CI: 4.57–5.36)) after adjustment for number of lifetime sexual partners and socio-demographic variables. The risk associated with uncircumcised status is significantly lower among younger men aged 15 – 29 years than those in 30 – 59-year age category. About 5.5% of the study subjects reported either genital discharge or genital sore/ulcer in the preceding 12 months of the surveys. Circumcision status was not significantly associated with either of the symptoms, with adjusted OR of 1.07 (95% CI: 0.99 – 1.15). The study concludes that there is a strong association between uncircumcised status and HIV infection. Hence, male circumcision can be considered as a possible way of reducing the spread of HIV infection in areas where the practice is rare. A comprehensive study to assess the association between circumcision and different types of STDs is recommended.  相似文献

Objectives

The incidence of sexually transmitted infections (STIs) and HIV infection remains high in gay, bisexual, and other men who have sex with men (MSM) in the UK, and sexualized drug use (“chemsex”) and injecting drug use (“slamsex”) may play a part in this. We aimed to characterize HIV‐positive MSM engaging in chemsex/slamsex and to assess the associations with self‐reported STI diagnoses and sexual behaviours.

Methods

Data from a 2014 survey of people attending HIV clinics in England and Wales were linked to clinical data from national HIV surveillance records and weighted to be nationally representative. Multivariable logistic regression assessed the associations of chemsex and slamsex with self‐reported unprotected anal intercourse (UAI), serodiscordant UAI (sdUAI) (i.e. UAI with an HIV‐negative or unknown HIV status partner), sdUAI with a detectable viral load (>50 HIV‐1 RNA copies/mL), hepatitis C, and bacterial STIs.

Results

In the previous year, 29.5% of 392 sexually active participants engaged in chemsex, and 10.1% in slamsex. Chemsex was significantly associated with increased odds of UAI [adjusted odds ratio (AOR) 5.73; < 0.001], sdUAI (AOR 2.34; < 0.05), sdUAI with a detectable viral load (AOR 3.86; < 0.01), hepatitis C (AOR 6.58; < 0.01), and bacterial STI diagnosis (AOR 2.65; < 0.01). Slamsex was associated with increased odds of UAI (AOR 6.11; < 0.05), hepatitis C (AOR 9.39; < 0.001), and bacterial STI diagnosis (AOR 6.11; < 0.001).

Conclusions

Three in ten sexually active HIV‐positive MSM engaged in chemsex in the past year, which was positively associated with self‐reported depression/anxiety, smoking, nonsexual drug use, risky sexual behaviours, STIs, and hepatitis C. Chemsex may therefore play a role in the ongoing HIV and STI epidemics in the UK.  相似文献

Summary. The aim of this study was to measure the impact of hepatitis C virus (HCV) infection on mortality in a cohort of inner city residents. The Community Health and Safety Evaluation is a community‐based study of inner city residents followed retrospectively and prospectively through linkages with provincial virology and mortality databases. We identified participants having received HCV antibody testing, evaluated cause‐specific mortality rates and factors associated with all‐cause and liver‐related mortality using Cox Proportional Hazards models. Overall, 2332 participants received HCV antibody testing (recent non‐injection drug use – 81%). The prevalence of HCV and HIV was 64% (1495 of 2332) and 21% (485 of 2332), respectively. Between January 2003 and December 2007, there were 180 deaths (192 per 10 000 person‐years; 95% CI: 165, 222), with 21% HIV‐related, 20% drug‐related and 7% liver‐related. Mortality was associated with age >50 [adjusted hazard ratio (AHR) 2.80 vs <40 years (referent group); 95% CI 1.93, 4.07, P < 0.001] and HIV infection (AHR 3.81; 95% CI 2.72, 5.34, P < 0.001), but not positive HCV antibody status (AHR 1.19; 95% CI 0.83, 1.72, P = 0.35). Liver‐related mortality was associated with age >50 [AHR 18.49 vs <40 years (referent group); 95% CI 2.27, 150.41, P < 0.001] and positive HCV antibody status (AHR 7.69; 95% CI 0.99, 59.98, P = 0.052). This study demonstrates a high rate of mortality in this population, particularly those with HIV. HCV‐infected inner city residents >50 years of age were at significant risk of liver‐related mortality. Continued surveillance of this population infected with HCV in the 1970s and 1980s is important.  相似文献

Although many researchers found that drug use behaviors significantly increased HIV risk, few of them investigated the association between HIV risk and different drug use behaviors among female sex workers (FSWs) in China. The current study examines demographic and behavioral risk factors as well as the infections of HIV, syphilis, and among a subgroup of FSWs who are injection drug users (IDU) or noninjection drug users (NIDU) in comparison to Hepatitis C Virus (HCV) nondrug users (non-DU). We conducted secondary analysis of the 2010 National Sentinel Surveillance (NSS) data from Guangxi China. A self-administered, standard behavioral surveillance survey was completed by a total of 12,622 FSWs recruited from Guangxi, China. The Guangxi 2010 NSS sample included 2.6% NIDU and 0.5% IDU. Compared to non-DU, IDU were more likely to report no condom use in the last sex act (aOR = 3.25, 95%CI = 1.65, 6.40), inconsistent condom use in the past month (aOR = 4.88, 95%CI = 2.66, 8.96), having an HIV testing (aOR = 2.48, 95%CI = 1.34, 4.58), infections of HIV (aOR = 42.60, 95%CI = 9.45, 192.06), syphilis (aOR = 4.13, 95%CI = 1.86, 9.16), and HCV (aOR = 74.54, 95%CI = 30.26, 183.61). NIDU had 2.89 times higher than non-DU to report a history of sexually transmitted disease and 26% less likely to report inconsistent condom use in the past month (p < 0.05). We called for tailored, accessible, and nonjudgmental drug treatments coupled with effective sexual risk reduction interventions to help FSWs with various drug use problems to reduce their vulnerability and susceptibility of HIV risk in China as well as other cultural settings.  相似文献

Summary.  Infection with hepatitis C virus (HCV) may suppress co-infection with hepatitis B virus (HBV) during acute or chronic HBV infection. We examined relationships between HBV infection, HCV infection and other factors among injection drug users (IDUs) with antibodies to both viruses. Participants enrolled in a cross-sectional study during 1998–2000 were considered to have been infected with HBV if they had core antibody, to be chronically infected if they had hepatitis B surface antigen (HBsAg), to have been infected with HCV if they had HCV antibody and to be chronically infected if they had HCV RNA. Among 1694 participants with antibody to both viruses, HBsAg prevalence decreased with increasing age among those positive for HCV RNA [from 4.55% in those 18–29 years to 1.03% in those ≥50 years old ( P trend = 0.02)], but not among those who were negative for HCV RNA. Chronic HBV infection was less common overall among those with chronic HCV infection (odds ratio [OR], 0.25; P  < 0.0001), but this inverse relationship was much stronger in the oldest (>50 years; OR = 0.15) than the youngest (18–29 years; OR = 0.81) participants ( P trend = 0.03). Similar results were obtained when duration of injection drug use was substituted for age ( P trend = 0.05). Among IDUs who have acquired both HBV and HCV, chronic HBV infection is much less common among those with chronic HCV infection, but this inverse relationship increases markedly with increasing years of age and injection drug use. Co-infection with HCV may enhance the resolution of HBsAg during the chronic phases of these infections.  相似文献

Background: New technologies and therapies allow the possibility of a single-visit test and treat model for hepatitis C virus (HCV), addressing some of the barriers to care faced by people who inject drugs. Methods: The TEMPO Pilot Study was an interventional cohort study evaluating a single-visit test and treat intervention among people with recent injecting drug use at a one peer-led needle and syringe program (NSP) in Sydney, Australia between September 2019 and February 2021. This analysis evaluated awareness of HCV status and agreement of self-report with HCV RNA test results. The analysis also assessed acceptability of: modality of result delivery, modality of blood sampling, site of treatment, and duration of treatment. Results: Among 101 participants (median age 43; 31% female), 100 had a valid HCV RNA test result and 27% (27/100) were HCV RNA detectable. Overall, 65% (65/100) were aware of their status. Among people with a positive HCV RNA result, 48% (13/27) were aware of their status. People preferred same-day HCV test results (95%, 96/101), and preferred to receive results in person (69%, 70/101). Receiving treatment at an NSP was acceptable (100%, 101/101) and 78% (79/101) were willing to discuss their health with a peer NSP worker. Conclusion: Half of people with current HCV infection were aware of their status. The high acceptability of simplified testing and treatment pathways delivered at NSPs indicates that this is an appropriate strategy to improve HCV awareness and treatment uptake in this population.  相似文献

Highly active antiretroviral therapy (HAART) has reduced the incidence of death in HIV-infected patients but various rates of survival have been reported due to the infection with hepatitis C virus (HCV) and the use of injecting drugs (IDU). A survival analysis was performed to estimate and compare the death rates in HIV-positive patients infected by IDU and/or positive for HCV antibodies in the pre-HAART and HAART periods in Lyon (France) between 1992 and 2002. Patients were stratified into four groups (G): HCV-/IDU-(G1), HCV+/IDU-(G2), HCV+/IDU-(G3), HCV+/IDU+ (G4) and adjusted death rates in the pre-HAART era (< 1996) and the HAART era (> or = 1996) were compared. The aHR of progression to death was 1.05 (95% CI 0.75-1.47, P = 0.75) for G2, 1.09 (95% CI 0.54-2.22, P = 0.81) for G3 and 0.90 (95% CI 0.65-1.24, P =0.51) for G4 compared with G1 in the pre-HAART era. The aHR of progression to death was 0.76 (95% CI 0.28-2.08, P = 0.59) for G2, 1.23 (95% CI 0.17-8.86, P = 0.84) for G3 and 2.90 (95% CI 1.62-5.20, P < 0.001) for G4, compared with G1 in the HAART era. HAART management of HCV+/IDU+ patients needs to be optimized for them to achieve a similar benefit as observed among other individuals.  相似文献

BACKGROUNDLittle is known about the engagement in hepatitis C virus (HCV) care and completion of HCV treatment in people living with human immunodeficiency virus (HIV) (PLWH) who have HCV coinfection in the Asia-Pacific region. Examining the HCV care cascade can identify barriers to the completion of HCV treatment and facilitate achievement of HCV micro-elimination in PLWH.AIMTo investigate the care cascade of incident HCV infections among PLWH in Taiwan.METHODSPLWH with incident HCV infections, defined as HCV seroconversion, were retrospectively identified by sequential anti-HCV testing of all archived blood samples at National Taiwan University Hospital between 2011 and 2018. All PLWH with incident HCV infections were followed until December 31, 2019. The care cascade of HCV examined included all incident HCV-infected patients, the percentages of anti-HCV antibodies detected by HIV-treating physicians in clinical care, plasma HCV RNA load tested, HCV RNA positivity diagnosed, referral to treatment assessment made, anti-HCV treatment initiated, and sustained virologic response achieved. Those who had HCV seroconversion during the interferon (IFN) era (2011–2016) and the direct-acting antiviral (DAA) era (2017–2018) were analyzed separately. The duration of HCV viremia—from the date of seroconversion to viral clearance by treatments or until the end of observation—and the incidence of sexually transmitted infections (STIs) during the HCV viremic period were estimated.RESULTSDuring the study period, 287 of 3495 (8.2%) PLWH (92.3% being men who have sex with men) who were HCV-seronegative at baseline developed HCV seroconversion by retrospective testing of all archived blood samples. Of the 287 incident HCV infections, 277 (96.5%) had anti-HCV antibodies detected by HIV-treating physicians, 270 (94.1%) had plasma HCV RNA determined and 251 (87.5%) tested positive for HCV RNA. Of those with HCV viremia, 226 (78.7%) were referred to treatment assessment, 215 (74.9%) initiated anti-HCV treatment, and 202 (70.4%) achieved viral clearance. Compared with that in the IFN era, the median interval from HCV seroconversion by retrospective testing to detection of HCV seropositivity by HIV-treating physicians was significantly shorter in the DAA era {179 d [interquartile range (IQR) 87-434] vs 92 d (IQR 57-173); P < 0.001}. The incidence rate of STIs in the DAA vs the IFN era was 50.5 per 100 person-years of follow-up (PYFU) and 38.5 per 100 PYFU, respectively, with an incidence rate ratio of 1.31 (95% confidence interval 0.96-1.77), while the duration of HCV viremia was 380 d (IQR 274-554) and 735 d (IQR 391-1447) (P < 0.001), respectively.CONCLUSIONWhile anti-HCV therapies are effective in achieving viral clearance, our study suggests more efforts are needed to expedite the linkage of PLWH diagnosed with incident HCV infections to HCV treatment.  相似文献

ABSTRACT

Little is known about how interacting psychosocial problems may influence sexual behaviour among men having sex with men taking Pre-exposure prophylaxis (PrEP). This study assessed (1) the prevalence of depression, recreational drug-use and sexual risk behaviour; (2) changes in these psychosocial conditions over time; and (3) the interaction of drug use and depression with sexual risk behaviour. We analysed data of the Belgian Be-PrEP-ared cohort study (N?=?200). We assessed depression using the PHQ-9, recreational drug use and receptive condomless anal intercourse (rCAI) with anonymous partners. Frequencies of psychosocial problems were compared at baseline, 9 and 18 months follow-up (FU). Bivariate associations between depression and drug-use behaviour, and their interaction with rCAI with anonymous sexual partners using was examined using linear regression. Receptive CAI increased from 41% at baseline to 53% at M18 (p?=?0.038). At baseline, we found an interaction effect of poly-drug use and depression, potentiating rCAI with anonymous partners. Participants reporting poly-drug use associated with depression were significant more likely to report this type of sexual risk behaviour than those who did not report this association (p?=?0.030). The high level of intertwined psychosocial problems call for multi-level interventions for those PrEP users experiencing a syndemic burden.  相似文献

OBJECTIVES: To investigate the impact of harm-reduction programmes on HIV and hepatitis C virus (HCV) incidence among ever-injecting drug users (DU) from the Amsterdam Cohort Studies (ACS). METHODS: The association between use of harm reduction and seroconversion for human immunodeficiency virus (HIV) and/or hepatitis C virus (HCV) was evaluated using Poisson regression. A total of 714 DU were at risk for HIV and/or HCV during follow-up. Harm reduction was measured by combining its two most important components--methadone dose and needle exchange programme (NEP) use--and looking at five categories of participation, ranging from no participation (no methadone in the past 6 months, injecting drug use in the past 6 months and no use of NEP) to full participation (> or = 60 mg methadone/day and no current injecting or > or = 60 mg methadone/day and current injecting but all needles exchanged). RESULTS: Methadone dose or NEP use alone were not associated significantly with HIV or HCV seroconversion. However, with combination of these variables and after correction for possibly confounding variables, we found that full participation in a harm reduction programme (HRP) was associated with a lower risk of HIV and HCV infection in ever-injecting drug users (DU), compared to no participation [incidence rate ratio 0.43 (95% CI 0.21-0.87) and 0.36 (95% CI 0.13-1.03), respectively]. CONCLUSIONS: In conclusion, we found that full participation in HRP was associated with a lower incidence of HCV and HIV infection in ever-injecting DU, indicating that combined prevention measures--but not the use of NEP or methadone alone--might contribute to the reduction of the spread of these infections.  相似文献
