When HIV-Prevention Messages and Gender Norms Clash: The Impact of Domestic Violence on Women's HIV Risk in Slums of Chennai, India

This paper examines how marital violence affects womens ability to protect themselves from HIV/AIDS. In-depth interviews (n = 48) and focus groups (n = 84, 3–7 per group) were conducted among men and women in two randomly selected slums of Chennai, India. The study showed that community gender norms tacitly sanction domestic violence that interferes with adopting HIV-preventive behaviors. Given the choice between the immediate threat of violence and the relatively hypothetical specter of HIV, women often resign themselves to sexual demands and indiscretions that may increase their risk of HIV acquisition. In conclusion, AIDS-prevention interventions must incorporate gender-related social contexts in settings where husbands strictly enforce their locus of control. HIV-prevention messages targeting men may effectively reduce womens exposure to HIV/AIDS.

High HIV Prevalence and Risk Behaviors in Men Who Have Sex with Men in Chennai, India

ObjectiveTo estimate HIV and sexually transmitted disease (STD) prevalence and behavioral risk characteristics of men who have sex with men (MSM) in Chennai, India. MethodsA cross-sectional population-based random sample survey was conducted in 2001. Randomly selected residents of 30 slums in Chennai were interviewed for behavioral risk factors through face-to-face interviews. Sera and urine were examined for syphilis, HIV-1, gonorrhea, and chlamydia. Logistic regression analyses were used to assess associations between MSM status and HIV infection and to identify risk characteristics of MSM. ResultsOf 774 men, 46 reported (5.9%) sex with other men. MSM were more likely to be seropositive for HIV (odds ratio [OR] = 8.57; 95% confidence interval [CI]: 1.83, 40.23) and were more likely to have a history of STD (OR = 2.66; 95% CI: 1.18, 6.02) than non-MSM. Men who used illicit drugs in past 3 months (adjusted odds ratio [AOR] = 4.01; 95% CI: 1.92, 8.41), ever exchanged money for sex (AOR = 3.93; 95% CI: 1.97, 7.84), or were ever tested for HIV (AOR = 3.72; 95% CI: 1.34, 10.34) were significantly more likely to report sex with men. ConclusionsMSM in Chennai slums are at high risk for HIV. HIV prevention strategies aimed at changing unsafe drug and sexual practices should target the general population of men, with specific attention to areas with high rates of MSM.

High Prevalence of Hiv, Hiv/hepatitis C Virus Coinfection, and Risk Behaviors Among Injection Drug Users in Chennai, India: A Cause for Concern

Objective:To estimate the prevalence of HIV and hepatitis C virus (HCV) and hepatitis B virus (HBV) coinfections and current risk behaviors among HIV-positive and -negative injection drug users (IDUs) in Chennai, India. Methods:Cross-sectional analysis of a convenience sample of 912 IDUs recruited between March 2004 and April 2005. Specimens were tested for HIV, HBV, and HCV. Adjusted prevalence ratios (PRs) were estimated using Poisson regression with robust variance estimates. Results:The prevalence of HIV, hepatitis B surface antigen, and anti-HCV were 29.8%, 11.1%, and 62.1%, respectively. Among HIV-infected IDUs, prevalence of coinfection with anti-HCV and hepatitis B surface antigen/anti-HCV were 86% and 9.2%, respectively. In multivariate analysis, injecting at a dealers place (PR: 1.57) and duration of injection drug use ≥11 years (PR: 3.02) were positively associated with prevalent HIV infection. Contrastingly, alcohol consumption ≥1 per week (PR: 0.55) was negatively associated with HIV. HIV-positive IDUs were as or more likely compared with HIV-negative IDUs to report recent high-risk injection-related behaviors. Conclusions:There is a high burden of HIV, HCV, and HBV among IDUs that needs to be addressed by improving access to therapies for these infections; furthermore, preventive measures are urgently needed to prevent further spread of HIV, HBV, and HCV in this vulnerable population.

The impact of HIV and high-risk behaviours on the wives of married men who have sex with men and injection drug users: implications for HIV prevention.

BackgroundHIV/AIDS in India disproportionately affects women, not by their own risks, but by those of their partners, generally their spouses. We address two marginalized populations at elevated risk of acquiring HIV: women who are married to men who also have sex with men (MSM) and wives of injection drug users (IDUs).MethodsWe used a combination of focus groups (qualitative) and structured surveys (quantitative) to identify the risks that high-risk men pose to their low-risk wives and/or sexual partners. Married MSM were identified using respondent-driven recruitment in Tamil Nadu, India, and were interviewed by trainer assessors. A sample of wives of injection drug users in Chennai were recruited from men enrolled in a cohort study of the epidemiology of drug use among IDUs in Chennai, and completed a face-to-face survey. Focus groups were held with all groups of study participants, and the outcomes transcribed and analyzed for major themes on family, HIV and issues related to stigma, discrimination and disclosure.ResultsUsing mixed-methods research, married MSM are shown to not disclose their sexual practices to their wives, whether due to internalized homophobia, fear of stigma and discrimination, personal embarrassment or changing sexual mores. Married MSM in India largely follow the prevailing norm of marriage to the opposite sex and having a child to satisfy social pressures. Male IDUs cannot hide their drug use as easily as married MSM, but they also avoid disclosure. The majority of their wives learn of their drug-using behaviour only after they are married, making them generally helpless to protect themselves. Fear of poverty and negative influences on children were the major impacts associated with continuing drug use.ConclusionsWe propose a research and prevention agenda to address the HIV risks encountered by families of high-risk men in the Indian and other low- and middle-income country contexts.

Burden of hepatitis C virus disease and access to hepatitis C virus services in people who inject drugs in India: a cross-sectional study

BACKGROUND 90% of individuals infected with hepatitis C virus (HCV) worldwide reside in resource-limited settings. We aimed to characterise the prevalence of HCV, HIV/HCV co-infection, and the HCV care continuum in people who inject drugs in India. METHODS 14 481 people (including 31 seeds--individuals selected as the starting point for sampling because they were well connected in the drug using community) who inject drugs were sampled from 15 cities throughout India using respondent-driven sampling from Jan 2, 2013 to Dec 19, 2013. Data from seeds were excluded from all analyses. HCV prevalence was estimated by the presence of anti-HCV antibodies incorporating respondent-driven sampling weights. HCV care continuum outcomes were self-reported except for viral clearance in treatment-experienced participants. FINDINGS The median age of participants was 30 years (IQR 24-36) and 13 608 (92·4%) of 14 449 were men (data were missing for some variables). Weighted HCV prevalence was 5777 (37·2%) of 14 447; HIV/HCV co-infection prevalence was 2085 (13·2%) of 14 435. Correlates of HCV infection included high lifetime injection frequency, HIV positivity, and a high prevalence of people with HIV RNA (more than 1000 copies per mL) in the community. Of the 5777 people who inject drugs that were HCV antibody positive, 440 (5·5%) were aware of their status, 225 (3·0%) had seen a doctor for their HCV, 79 (1·4%) had taken HCV treatment, and 18 (0·4%) had undetectable HCV RNA. Of 12 128 participants who had not previously been tested for HCV, 6138 (50·5%) did not get tested because they had not heard of HCV. In the 5777 people who were HCV antibody positive, 2086 (34·4%) reported harmful or hazardous alcohol use, of whom 1082 (50·4%) were dependent, and 3821 (65·3%) reported needle sharing. Awareness of HCV positive status was significantly associated with higher education, HIV testing history, awareness of HIV positive status, and higher community antiretroviral therapy coverage. INTERPRETATION The high burden of HCV and HIV/HCV co-infection coupled with low-access to HCV services emphasises an urgent need to include resource-limited settings in the global HCV agenda. Although new treatments will become available worldwide in the near future, programmes to improve awareness and reduce disease progression and transmission need to be scaled up without further delay. Failure to do so could result in patterns of rising mortality, undermining advances in survival attributed to widespread HIV treatment. FUNDING US National Institutes of Health.

Crossing the threshold: engendered definitions of socially acceptable domestic violence in Chennai, India

The objective of this study was to examine the pathways by which gender norms may influence marital violence in low‐income communities of Chennai, India. As part of a multisite international behavioural HIV intervention trial, 48 in‐depth interviews and 14 focus groups with men and women were conducted in two randomly selected low‐income communities within the city. Interviews were taped, transcribed, translated, coded and analysed to identify recurrent themes. A multi‐layered conceptual framework was used to examine individual, relational, community and societal level determinants of marital violence in this setting. Participants noted that husbands hold decision‐making power in economic, social and sexual spheres. Clear patterns of violence were present; respondents reported that husbands regularly beat wives in most marriages. Marital conflicts were intensified by the presence of community level stressors such as poverty and unemployment. Participants perceived violence to be a necessary tool that served to discipline wives and ultimately enforce gender norms. Although many respondents felt wife‐beating was the norm, the acceptable intensity of violence varied by gender. Interventions that reconsider gender‐based roles and empower men and women to lower the threshold of socially acceptable violence should be developed to alleviate the consequences of violence.

Association of Hepatitis C Virus Infection with Sexual Exposure in Southern India

To determine the association between sexual exposure and hepatitis C virus (HCV) infection in urban Chennai, India, a random sample of adults who live in a slum community completed interviews and provided samples to test for HCV, herpes simplex virus type 2 (HSV-2), and other sexually transmitted infections (STIs). All analyses excluded recent and current injection drug users. HCV infection was not associated with the reported number of sex partners for men or women. Women were more likely to be HCV infected if they reported previous genital ulcer disease (adjusted odds ratio [AOR], 3.88; 95% confidence interval [95% CI], 0.94-16.0; marginally statistically significant). Men were more likely to be HCV infected if they were HSV-2 infected (AOR, 3.85; 95% CI, 1.18-12.6) or reported having had sex with men (AOR, 3.61; 95% CI, 1.00-13.1). Sexual transmission of HCV infection may be facilitated by ulcerative STIs and male-male sexual practices, but it appears to occur infrequently in this population.

Predictors of Nonadherence to Highly Active Antiretroviral Therapy Among HIV-Infected South Indians in Clinical Care: Implications for Developing Adherence Interventions in Resource-Limited Settings

In light of the increasing availability of generic highly active antiretroviral therapy (HAART) in India, further data are needed to examine variables associated with HAART nonadherence among HIV-infected Indians in clinical care. We conducted a cross-sectional analysis of 198 HIV-infected South Indian men and women between January and April 2008 receiving first-line non-nucleoside reverse transcriptase inhibitor (NNRTI)-based HAART. Nonadherence was defined as taking less than 95% of HAART doses in the last 1 month, and was examined using multivariable logistic regression models. Half of the participants reported less than 95% adherence to HAART, and 50% had been on HAART for more than 24 months. The median CD4 cell count was 435 cells per microliter. An increased odds of nonadherence was found for participants with current CD4 cell counts greater than 500 cells per microliter (adjusted odds ratio [AOR]: 2.22 [95% confidence interval {CI}: 1.04-4.75]; p = 0.038), who were on HAART for more than 24 months (AOR: 3.07 [95% CI: 1.35-7.01]; p = 0.007), who reported alcohol use (AOR: 5.68 [95%CI: 2.10-15.32]; p = 0.001), who had low general health perceptions (AOR: 3.58 [95%CI: 1.20-10.66]; p = 0.021), and who had high distress (AOR: 3.32 [95%CI: 1.19-9.26]; p = 0.022). This study documents several modifiable risk factors for nonadherence in a clinic population of HIV-infected Indians with substantial HAART experience. Further targeted culturally specific interventions are needed that address barriers to optimal adherence.

HIV/AIDS Stigma: Reliability and Validity of a New Measurement Instrument in Chennai, India

HIV/AIDS stigma is a frequently cited barrier to HIV prevention, including voluntary counseling and testing. A reliable and valid measurement instrument is critical to empirically assess the extent and effects of HIV/AIDS stigma. The paper reports the development and psychometric testing of an HIV/AIDS stigma scale among 200 men in India. The resulting 24-item scale and the four subscales had good internal consistency (Cronbachs alpha overall was 0.81; subscales were 0.86, 0.73, 0.72 and 0.76, respectively). The scale and distinct subscales suggest a valid and reliable measure for HIV/AIDS stigma in a setting with highly prevalent HIV risk behaviors.

The relationship between drug use stigma and HIV injection risk behaviors among injection drug users in Chennai, India.

BACKGROUND The purpose of this study was to examine the relationship between perceived drug use stigma, acquiescence response bias, and HIV injection risk behaviors among current injection drug users in Chennai, India. METHODS The sample consists of 851 males in Chennai, India who reported having injected drugs in the last month and were recruited through street outreach. RESULTS Results indicate a strong and consistent positive association between drug use stigma and HIV injection drug use risk behaviors. This association held across the injection behaviors of frequency of sharing needles, cookers, cotton filters, rinse water, pre-filled syringes and common drug solutions, even after controlling for acquiescence response bias, frequency of injection, and HIV/HCV serostatus. CONCLUSIONS These findings suggest that future HIV prevention and harm reduction programs for injection drug users and service providers should address drug use stigma.
