A rapid situation and response assessment of the female regular sex partners of male drug users in South Asia: Factors associated with condom use during the last sexual intercourse

Prevalence of HIV, risk behaviours and vulnerabilities of female sex partners of the HIV positive people who inject drugs (PWID) in Dhaka city, Bangladesh

Background

The HIV epidemic in Bangladesh is largely being driven by people who inject drugs (PWID) and mainly concentrated in Dhaka city. Intregrated biological and behavioural survey (IBBS) data of 2016 showed that a considerable percentage of the HIV positive PWID had unsafe sex with their female sex partners. Prevalence of HIV, risk behaviorus and vulnerabilities among the female sex partners of the PWID still remain unexplored.

Methods

To measure HIV prevalence, risk behaviours (drugs/injection/sexual) and vulnerabilities (treatment of and knowledge of sexually transmitted infections (STIs) and HIV/uptake of the routine HIV testing and HIV prevention services/physical and sexual violence), a quantitative survey was conducted among 227 female sex partners of the HIV positive PWID in Dhaka city in 2019 by adopting a take-all sampling technique.

Results

The median age of participants was 34.0 years. Prevalence of HIV was 16.7% (95% CI: 12.4–22.2). Only 6.8% to 18.7% of the participants used condoms consistently with different male sex partners; only 6.8%cto 18.7% during last year. Seventy five percent (95% CI: 69.2–80.8) had no knowledge on STI symptoms. Self-reported symptoms of STIs were reported by 26% (95% CI: 20.7–32.1) and half sought treatment during last year. Nineteen percent (95% CI: 14.7–25.1) had comprehensive knowledge of HIV. As part of the routine HIV prevention services by the PWID drop-in-centres (DICs), 42.7% (95% CI: 36.4–49.3) of the participants were tested for HIV and knew their result within the last year. One-third never received HIV prevention services. During the last one year preceding the survey, 46% (95% CI: 39.3–52.6) reported been beaten and 20.2% (95% CI: 15.3–26.1) been raped.

Conclusion

It is urgently necessary to consider the high-risk behaviours and vulnerabilities in designing or to strengthen targeted interventions for female sex partners of the HIV positive PWID in Dhaka city to ensure equality in accessing and utilization of services.

Prevalence and associated factors of sexually transmitted infections among methamphetamine users in Eastern China: a cross-sectional study

BACKGROUND

The reported incidence of sexually transmitted infections (STIs) in China has been increasing over the last decades, especially among drug users, which has become one of the main burdens of public health in China. This study was conducted to estimate the prevalence and associated factors of STIs among non-injecting methamphetamine (MA) users in Eastern China.

METHODS

A cross-sectional survey was conducted among 632 MA users in Eastern China in 2017. Demographic characteristics, sexual behaviors, behaviors of MA use and sexual health knowledge were collected through questionnaire. First pass urine specimens were collected and detected for deoxyribonucleic acid (DNA) of Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) with Nucleic Acid Amplification Technology (NAAT), while blood specimens were collected and detected for antibodies of Human immunodeficiency virus (HIV), Herpes simplex virus type-2 (HSV-2), and syphilis with enzyme-linked immune sorbent assay (ELISA).

RESULTS

Among the 632 MA users, 464 (73.42%) were males, 60.92% were < 35 years of age, 546 (86.39%) were Shandong residents. 317 (50.16%, 95% CI 46.26-54.06%) participants were tested positive for at least one kind of STIs, including 242 (38.29%, 95% CI 34.50-42.08%) for HSV-2, 107 (16.93%, 95% CI 14.01-19.85%) for active syphilis, 46 (7.28%, 95% CI 5.25-9.31%) for treated syphilis, 40 (6.33%, 95% CI 4.43-8.23%) for CT, 6 (0.95%, 95% CI 0.19-1.71%) for HIV, and 3 (0.47%, 95% CI 0.06-1.00%) for NG infection. 99 (15.66%, 95% CI 12.83-18.49%) participants were co-infected with two kinds of STIs, including 91 (14.40%, 95% CI 11.66-17.14%) participants were co-infected with HSV-2 and syphilis. 14 (2.22%, 95% CI 1.07-3.37%) participants were co-infected with three kinds of STIs, and 4 HIV positive participants were co-infected with both syphilis and HSV-2. In the multiple logistic regression analysis, the results showed that females (adjusted OR [AOR] = 7.30, 95% CI 4.34-12.30) and individuals ≥ 35 years of age (AOR = 2.97, 95% CI 2.04-4.32) were more likely to test positive for STIs among MA users, whereas participants who acquired sexual health knowledge primarily from the Internet (AOR = 0.57, 95% CI 0.40-0.82) and those whose regular partners did not use drugs (AOR = 0.59, 95% CI 0.37-0.94) were less likely.

CONCLUSIONS

This study found that the prevalence of HSV-2 and syphilis are alarming high among non-injecting MA users in Shandong Province in Eastern China. The prevention and control intervention of STIs among MA users in Shandong were needed, especially on females and MA users ≥ 35 years of age.

Consistent condom use and its predictors among female sexual Partners of People who Inject Drugs in Klang Valley, Malaysia

BACKGROUND

Men who inject drugs (MWIDs) comprise the highest percentage of diagnosed HIV cases in Malaysia. Their female partners risk being infected through unprotected sexual contact. This paper reports the prevalence of consistent condom use and its predictors among the wives and regular sexual partners of MWIDs in Klang Valley, Malaysia.

METHODS

A cross-sectional study using a self-administered questionnaire was conducted among the wives and regular sexual partners of MWIDs in the study location; 221 women were recruited through respondent-driven sampling. Data were analysed descriptively for the prevalence of consistent condom use, HIV status and HIV risk-related behaviour. Subsequently, simple and multiple logistic regressions were undertaken to identify the predictors of consistent condom use.

RESULTS

The prevalence of consistent condom use among respondents was 19.5%. Slightly more than half (52.5%) of respondents had never used condoms with their partner. Fourteen women (6.3%) reported being HIV positive. While 7.7% had HIV-positive partners, 45.7% were unaware of their partner's HIV status. Consistent condom use was significantly higher among single women (AOR = 4.95; 95% CI: 2.45, 9.99), women who lived in urban areas (AOR = 2.97; 95% CI: 1.30, 6.78), HIV-positive women (AOR = 3.45; 95% CI: 1.13, 10.5) and women involved in sex work (AOR = 3.55, 95% CI: 1.45, 8.67).

CONCLUSIONS

Inconsistent condom use among the majority of female sexual partners of MWIDs underscores the heightened risk faced by these women and calls for alternative prevention methods that women are able to control.

Sexual violence and the risk of HIV transmission in sexual partners of male injecting drug users in Tien Du district, Bac Ninh province of Vietnam

We conducted a cross-sectional study among 148 women who were regular sexual partners of male injecting drug users in Tien Du, Bac Ninh province, Vietnam to identify the rate of HIV infection and factors associated with HIV transmission among them. HIV infection rate among sexual partners was high, 11.5%. Sexual violence was prevalent, 63.5% among sexual partners; 94.1% (16/17) among those with HIV. We discovered an association between sexual violence and HIV infection. Sexual partners suffering from sexual violence caused by their regular sexual partners faced 9.24 times higher HIV risk than those who did not have sexual violence.

Patterns of HIV testing, drug use, and sexual behaviors in people who use drugs: findings from a community-based outreach program in Phnom Penh, Cambodia

Background

People who use drugs are an important priority for HIV programs. However, data related to their utilization of HIV services are limited. This paper reports patterns of HIV testing, drug use, and risk and service perception among people who use drugs. Study participants were receiving HIV and harm reduction services from a community-based program in Phnom Penh, comprised of itinerant peer-led outreach and static drop-in centers.

Methods

This was a mixed-methods study conducted in 2014, comprising of a quantitative survey using a structured questionnaire, followed by two focus group discussions among a sub-sample of survey participants. Participants were recruited from hotspots in five HIV high-burden communes using a two-stage cluster sampling method. Quantitative descriptive analyses and qualitative thematic analyses were performed.

Results

This study included 151 people who use drugs with a mean age of 31.2 (SD = 6.5) years; 77.5% were male and 39.1% were married. The most common drugs used were methamphetamines (72.8%) and heroin (39.7%), and 38.0% injected drugs in the past 3 months. Overall, 83.3% had been tested for HIV in the past 6 months, of whom 62.5% had been tested by peers through community-based outreach. However, there were ongoing HIV risks: 37.3% were engaging in sex on drugs, only 35.6% used a condom at last sexual intercourse, and 10.8% had had a sexually transmitted infection in the last 6 months. Among people who reported injecting drugs in the past 3 months, 27.5% reported re-using needles/syringes. Almost half (46.5%) perceived themselves as being at lower risk of HIV compared to the general population. Qualitative results contextualized the findings of low perception of HIV risks and suggested that although services were often unavailable on weekends, at night, or during national holidays, peer-led community-based outreach was highly accepted.

Conclusions

A peer-led community-based approach was effective in reaching people who use drugs with HIV and harm reduction interventions. To mitigate ongoing HIV risks, expanding access to combination prevention interventions and implementing strategies to enable people who use drugs to objectively assess their HIV risks are required. Additionally, community-based programs should collect data along the care continuum, to enable decentralized tracking of progress towards 90–90–90 goals at local levels.

The female crack users: Higher rates of social vulnerability in Brazil

Female crack users who sought treatment are a hard to find part of the population. We studied sociodemographic and behavioral characteristics of crack users undergoing treatment in psychosocial care centers for alcohol and other drugs in six Brazilian cities. We carried out a cross-sectional study of 816 crack users and collected data with the Addiction Severity Index. Women were more likely to be in vulnerable situations: had worst levels of education, were not receiving money enough to their basic needs; more likely to be HIV positive (10.1%), to report sexual abuse (34%), and to be separated from their children (20%).

Tobacco Consumption Among HIV-Positive Respondents: Findings From the Third Round of the National Family Health Survey

INTRODUCTION

HIV-positive people are often more susceptible to illnesses associated with smoking, for example, cardiovascular disease, than those in the general population. The purpose of this article is to examine the association between tobacco use and HIV-status in India.

METHODS

This article analyzed data from the National Family Health Survey III, which provides a representative sample of the Indian population. Patterns in tobacco consumption among HIV-positive and negative respondents were assessed through logistic and ordinal regression models. Associations between smoking, asthma, and tuberculosis were examined through bivariate logistic regressions.

RESULTS

A greater percentage of male HIV-positive participants (68%) reported current tobacco use in comparison to male HIV-negative respondents (58%) and female HIV-positive (12%) and negative (11%) participants. Multivariable logistic regression analyses revealed that there was a positive correlation between male respondents' HIV-status and their propensity to use tobacco (odds ratio [OR] = 1.48, confidence interval [CI] = 1.05-2.1, P < .05) when controlled for extraneous variables. Results from ordinal regression analyses illustrated that male HIV-positive respondents had a twofold increased OR of smoking 20 or more cigarettes (OR = 2.1, CI = 1.4-3.2, P < .005). Finally, there was a positive association between being HIV-infected (adjusted odds ratio [AOR] = 4.6, CI = 2.02-10.6, P < .005), smoking 15-19 cigarettes (AOR = 2.11, CI = 1.1-4.1, P < .05) and male participants' TB-status.

CONCLUSIONS

Results in this article suggest HIV-positive men in India were not only significantly more likely to consume tobacco, but they also smoked a higher number of cigarettes compared to their HIV-negative counterparts. This is a cause for concern as our analyses revealed a possible association between the number of cigarettes smoked and TB-status.

IMPLICATIONS

This article contributes to knowledge on the intertwining epidemics of HIV and smoking through using cross-sectional data from the National Family Survey III to demonstrate that HIV-positive men in India display patterns of tobacco consumption which differs to that of HIV-negative men. These findings could have strong implications for long-term treatment of HIV-positive patients as smoking has been proven to increase the likelihood of contracting HIV-related illnesses.

High HIV Prevalence and Associated Risk Factors Among Female Sexual Partners of Male Injection Drug Users (MWID) in Ho Chi Minh City, Vietnam

Injection drug use is a major factor in acquiring and transmitting HIV in Vietnam. This analysis aims to present estimates of HIV infection and factors associated with HIV infection among female sex partners (FSP) of MWID in Ho Chi Minh City (HCMC), Vietnam. Cross-sectional surveys were conducted in 2011 and 2013 among males who inject drugs (MWID) who then referred their FSP for a behavioral and biologic survey. In total, 445 MWID and FSPs were enrolled. HIV prevalence among MWID was 50 and 35 % among FSPs. Among FSPs, 60.3 % reported ever using illegal drugs and among those, 72.7 % reported ever injecting illicit drugs. Among FSP, injection drug for >1 year [adjusted Odds Ratio (aOR), 95 % CI 2.94, 1.19-7.26), p value = <0.001] and having a male partner infected with HIV [(aOR 3.35: 1.97-5.69), p value = <0.001] were associated with HIV infection. The prevalence of HIV infection is high among FSP of MWID in HCMC and is highly associated with the injection drug use behavior of the FSP. Harm-reduction intervention programs that focus on the MWID-FSP couple or directly on the FSPs are required.

Female sexual partners of male people who inject drugs in vietnam have poor knowledge of their male partners' HIV status

BACKGROUND

Vietnam's HIV epidemic is concentrated among male people who inject drugs (PWID), and their female sexual partners (SPs) may be at risk for infection. HIV prevention interventions for SPs were implemented in Hanoi, Dien Bien Province, and Ho Chi Minh City (HCMC), and data from linked surveys used to evaluate these interventions offered an unusual opportunity to assess knowledge of HIV status within couples.

METHODS

Linked surveys (behavioral interviews and HIV testing) among 200 PWID-SP couples in Hanoi, 300 in Dien Bien, and 249 in HCMC.

RESULTS

HIV prevalence among male PWID was 53% in Hanoi, 30% in Dien Bien, and 46% in HCMC, and lower among their SPs: 44%, 10%, and 37%, respectively. Comparison of SPs' beliefs regarding male PWID partners' HIV status with the PWIDs' actual test results revealed that 32% of SPs in Dien Bien and 44% in Hanoi and HCMC lacked correct knowledge of their male partners' status. This proportion was slightly lower (21%-33%) among SPs whose PWID partners reported having been previously tested and received HIV+ results.

CONCLUSIONS

SP interventions reached HIV-negative women in serodiscordant relationships, and some improvements occurred in condom use and relationship characteristics. Nevertheless, our findings suggest that at least 11,000 SPs in Vietnam may be at high risk for HIV infection because of incorrect knowledge of their partners' HIV status. Interventions should be strengthened in HIV testing, disclosure, and treatment, as well as empowerment of SPs as individuals, within couples, and as communities.

Sexual behaviours of men who inject drugs in northeast India

Background

Promoting safer sex behaviours among people who inject drugs is important as drug-using populations with high HIV prevalence can contribute to transition from a concentrated to a generalised epidemic. This study describes the sexual behaviours of men who inject drugs in two Northeast Indian states (Manipur and Nagaland) where HIV prevalence is high, with a focus on the HIV risks for their regular female sexual partners.

Methods

Data were obtained from two cross-sectional surveys combined (N = 3,362)—both conducted in 2009 using respondent-driven sampling to recruit men who injected drugs. Both surveys asked about demographics, drug use, sexual and injecting risk behaviours, and interventions. One survey tested participants for HIV and syphilis. Statistical analyses included logistic regression modelling to predict inconsistent condom use with regular sexual partners.

Results

Two thirds of participants (68.2%) had a regular female sexual partner. Of these, 78.4% had sex with their regular partner in the last month, on average five times. Only 10.7% reported consistent condom use with regular partners. Unsafe injecting was common among men with regular partners, and 40.2% had more than one sexual partner in the last year. Half of those with regular partners (51.0%) had never had an HIV test, and 14.3% of those tested were HIV positive. After controlling for confounding, inconsistent condom use with regular partners was associated with being illiterate, married, sharing needle and syringe with others, never having had an HIV test and not receiving condoms from an NGO.

Conclusion

The findings from this study among men who inject drugs in Manipur and Nagaland highlight the risk of HIV infection for their regular female sexual partners. Promoting better uptake of HIV testing among men who inject drugs will potentially benefit both them and their regular partners. While effectively reaching regular partners is challenging, a number of strategies for improving their situation in relation to HIV prevention are available.

'Women at risk': the health and social vulnerabilities of the regular female partners of men who inject drugs in Delhi, India

Needle and syringe sharing is common among people who inject drugs and so is unprotected sex, which consequently puts their sex partners at risk of sexually transmitted infections (STIs) including HIV and other blood-borne infections, like hepatitis. We undertook a nested study with the regular female partners of men who inject drugs participating in a longitudinal HIV incidence study in Delhi, India. In-depth interviews were conducted with female partners of 32 men. The interviews aimed to gather focused and contextual knowledge of determinants of safe sex and reproductive health needs of these women. Information obtained through interviews was triangulated and linked to the baseline behavioural data of their partner (index men who injected drugs). The study findings illustrate that women in monogamous relationships have a low perception of STI- and HIV-related risk. Additionally, lack of awareness about hepatitis B and C is a cause of concern. Findings also suggest impact of male drug use on the fertility of the female partner. It is critical to empower regular female partners to build their self-risk assessment skills and self-efficacy to negotiate condom use. Future work must explore the role of drug abuse among men who inject drugs in predicting fertility and reproductive morbidity among their female partners.

HIV/AIDS-Related Knowledge and Behaviors Among Most-at-Risk Populations in Vietnam

The U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) has supported the Vietnamese Ministry of Health (MOH) in implementing behavior change strategies to slow the HIV epidemic. These programs target commercial sex workers (CSW), injection drug users (IDU), and men who have sex with men (MSM). Using data from a program evaluation to assess effectiveness of the PEPFAR intervention, we conducted a sub-analysis of HIV/AIDS knowledge, sexual behaviors, and injection drug risk behaviors among 2,199 Vietnamese respondents, including those reporting recent contact with an outreach worker and those who did not report contact. We found overall high levels of HIV/AIDS knowledge, low rates of needle sharing, and moderate to high rates of inconsistent condom use. Average knowledge scores of IDU were significantly higher than non-IDU for antiretroviral treatment knowledge, while MSM had significantly less knowledge of treatment compared to non-MSM. HIV/AIDS-related knowledge was not significantly associated with needle-sharing practices. Knowledge was modestly but significantly associated with more consistent use of condoms with primary and commercial sex partners, even after controlling for contact with an outreach worker. Contact with an outreach worker was also an independent predictor of more consistent condom use. Outreach programs appear to play a meaningful role in changing sexual behavior, though the effect of outreach on IDU risk behaviors was less clear. More research is needed to understand the relationship between outreach programs and skill development, motivation, and use of referral services by most-at-risk populations in Vietnam.

HIV prevention interventions for female sexual partners of injection drug users in Hanoi, Vietnam: 24-month evaluation results

Vietnam's HIV epidemic is driven by injection drug use. Most IDUs are sexually active and may infect their female sexual partners (SPs). We implemented peer-based HIV prevention interventions for SPs in Hanoi. This paper reports on an evaluation of these interventions based on cross-sectional surveys of SPs. Our data show that this population can be reached, relationships improved, and consistent condom use increased (27% at 24 months up from 16% at 12 months: P = 0.002). Self-reported condom use at last sex was 3.5 times higher among participants in the intervention than among non-participants after controlling for selection bias, indicating a possible intervention effect. However, no significant association was found for consistent condom use in the previous 6 months. Many SPs remain at risk for HIV and interventions must promote a range of HIV prevention strategies including consistent condom use, lower risk sexual activity, and ARV treatment as prevention.

HIV serodiscordant relationships in India: translating science to practice

Over the past 30 years, several interventions have been identified to prevent HIV transmission from HIV-infected persons to uninfected persons in discordant relationships. Yet, transmissions continue to occur. Interventions such as voluntary counselling and testing, condom promotion and risk reduction counselling are very effective in preventing transmission among serodiscordant couples but are underutilized in India despite their widespread availability. New interventions such as pre-risk exposure prophylaxis and universal antiretroviral therapy (irrespective of CD4 count) have been newly identified but face several challenges that impede their widespread implementation in India. Discordant couples in India also face certain unique socio-cultural issues such as marital and fertility pressure. We briefly review the various interventions (existing and novel) available for persons in discordant relationships in India and socio-cultural issues faced by these individuals and make recommendations to maximize their implementation.

Reasons for non- use of condoms and self- efficacy among female sex workers: a qualitative study in Nepal

Background

Heterosexual contact is the most common mode of transmission of sexually transmitted infections (STIs) including Human Immunodeficiency Virus (HIV) in Nepal and it is largely linked to sex work. We assessed the non-use of condoms in sex work with intimate sex partners by female sex workers (FSWs) and the associated self-efficacy to inform the planning of STI/HIV prevention programmes in the general population.

Methods

This paper is based on a qualitative study of Female Sex Workers (FSWs) in Nepal. In-depth interviews and extended field observation were conducted with 15 FSWs in order to explore issues of safe sex and risk management in relation to their work place, health and individual behaviours.

Results

The main risk factor identified for the non-use of condoms with intimate partners and regular clients was low self efficacy. Non-use of condoms with husband and boyfriends placed them at risk of STIs including HIV. In addition to intimidation and violence from the police, clients and intimate partners, clients' resistance and lack of negotiation capacity were identified as barriers in using condoms by the FSWs.

Conclusion

This study sheds light on the live and work of FSWs in Nepal. This information is relevant for both the Government of Nepal and Non Governmental Organisations (NGO) to help improve the position of FSWs in the community, their general well-being and to reduce their risks at work.

Factors associated with HIV infection among Indian women

There is still a paucity of research on the sociodemographic and other underlying factors associated with HIV transmission among women in India. This study was designed to investigate such factors in sexually experienced Indian women. We used data from the National Family Health Survey 3 (NFHS-3), which tested 52,853 women for HIV, including 27,556 husband and wife pairs. Significant risk factors for all women and married women only were: aged 26-35 years (adjusted odds ratios [AORs] = 3.65 and 2.53, respectively), being poor (AORs = 1.57 and 1.79), having had a genital sore in the last 12 months (AORs = 3.16 and 3.01) and having more than one sexual partner (AORs = 5.95 and 5.15). For husband and wife pairs, suffering sexual violence (AOR = 2.63), husband having other wife/wives (AOR = 3.40) and husband's education being secondary level or higher (AOR = 0.43) were significant. Intervention strategies in India should target young married (aged 25-35 years) and formerly married urban women who are poor, as well as those who have suffered sexual violence from their husbands, and/or are (or whose husbands are) multi-partnered. Empowerment of women is fundamental to HIV/AIDS prevention in India.

Female sexual partners of injection drug users in Vietnam: an at-risk population in urgent need of HIV prevention services

Vietnam's HIV epidemic has been driven by injection drug use, with HIV prevalence among injection drug users (IDUs) of ~30%. Most IDUs are sexually active and may infect their female sexual partners (SPs). Male dominance in sexual decisions is deeply embedded in Vietnamese culture. There have been few HIV prevention interventions for SPs, who represent an important potential bridging population in the epidemic. We report findings from a baseline survey of SPs conducted in 2008 in Hanoi, Vietnam, where peer-based HIV prevention interventions targeting this population are now being implemented. The survey revealed HIV prevalence of 14% among SPs in Hanoi and only 27% reported condom use with their primary male partners half the time or more. About 69% of SPs were in serodiscordant or unknown HIV status relationships but condom use was not more frequent in these relationships than in concordant partnerships. Many SPs feared angry or violent responses if they requested condom use, problems that were even more likely in serodiscordant/unknown status relationships. SPs also reported limited prior access to HIV prevention services. Many SPs in Vietnam are at high risk for HIV and in need of HIV prevention interventions. However, to date, this population has been seriously underserved. Our interventions are in progress and results will be reported subsequently.

Contraception use and unplanned pregnancies among injection drug-using women in St Petersburg, Russia

BACKGROUND

This cross-sectional study estimated the prevalence of contraceptive methods and investigated whether abortion rates influence contraceptive behaviour among injection drug-using (IDU) women in St Petersburg, Russia.

METHODOLOGY

A self-administered questionnaire of behaviour in the last 3 months was applied to a convenient sample of IDU women.

RESULTS

Of 80 sexually active participants, 67% had had an abortion. No participant reported using hormonal contraceptives or intrauterine devices (IUDs). The only valid method of contraception used was condoms, which was reported by half of the participants. Consistent condom use was reported by 22% of participants and was no more likely among those who had an abortion. Condom use was significantly associated with having multiple or casual sex partners [prevalence ratio (PR) 1.75, 95% (confidence interval) CI 1.11-2.78, p = 0.01], having an IDU sex partner (PR 0.55, 95% CI 0.36-0.85, p = 0.029) and with a negative attitude toward condoms (PR 0.53, 95% CI 0.33-0.84, p = 0.01). Abortions were less likely among those who had multiple or casual sex partners (PR 0.69, 95% CI 0.49-0.97, p = 0.03).

CONCLUSIONS

Despite the high prevalence of abortions among IDU women, none reported the use of hormonal contraception or IUDs. Having had an abortion was not associated with greater likelihood of using condoms. Participants mostly used condoms with casual or multiple sex partners, suggesting that condoms were used mainly to prevent HIV/sexually transmitted infection transmission and not to prevent pregnancy. Programmes to prevent unwanted pregnancies and reduce abortion-related health risks among this understudied vulnerable group are needed.

The intersection between sex and drugs: a cross-sectional study among the spouses of injection drug users in Chennai, India

Background

It is estimated that there are up to 1.1 million injection drug users (IDUs) in India; the majority are likely married. We characterize HIV, hepatitis B (HBV) and hepatitis C (HCV) prevalence and the risk environment of a sample of spouses of IDUs.

Methods

A cohort of 1158 IDUs (99% male) was recruited in Chennai, India from 2005-06. A convenience sample of 400 spouses of the male IDUs in this cohort was recruited in 2009. A risk assessment questionnaire was administered and a blood sample collected. Logistic regression was used to identify factors associated with prevalent HIV.

Results

Median age was 31 years; thirteen percent were widowed and 7% were not currently living with their spouse. Only 4 (1%) reported ever injecting drugs; Twenty-two percent and 25% reported ever using non-injection drugs and alcohol, respectively. The majority had one lifetime sexual partner and 37 (9%) reporting exchanging sex. Only 7% always used condoms with their regular partner. HIV, HBV and HCV prevalence were 2.5%, 3.8% and 0.5%, respectively; among spouses of HIV+ IDUs (n = 78), HIV prevalence was 10.3%. The strongest predictor of HIV was spousal HIV status (OR: 17.9; p < 0.001). Fifty-six percent of women had ever experienced intimate partner violence; Eight-six percent reported sexual violence.

Conclusions

Our finding of a 10-fold higher HIV prevalence among spouses of IDUs compared with general population women indicates their vulnerability; prevalence is likely to increase given the context of low condom use and frequent sexual violence. Prevention efforts directed at IDUs should also include programs for spouses.

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

Background

HIV/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).

Methods

We 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.

Results

Using 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.

Conclusions

We 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.
