High Pregnancy Intentions and Missed Opportunities for Patient–Provider Communication About Fertility in a South African Cohort of HIV-Positive Women on Antiretroviral Therapy

High fertility intentions amongst HIV-positive women have been reported elsewhere. Less is known about how clinical and HIV treatment characteristics correlate with fertility intentions. We use cross-sectional baseline data from a prospective cohort study to assess pregnancy intentions and patient–provider communication around fertility. Non-pregnant, HIV-positive women aged 18–35 on ART were recruited through convenience sampling at Johannesburg antiretroviral (ART) treatment facilities. Among the 850 women in this analysis, those on efavirenz had similar fertility intentions over the next year as women on nevirapine-based regimens (33% vs. 38%). In multivariate analysis, recent ART initiation was associated with higher current fertility intentions; there was no association with CD4 cell count. Forty-one percent of women had communicated with providers about future pregnancy options. Women on ART may choose to conceive at times that are sub-optimal for maternal, child and partner health outcomes and should be routinely counseled around safer pregnancy options.

What they wanted was to give birth; nothing else: barriers to retention in option B+ HIV care among postpartum women in South Africa.

Background:Women initiating antiretroviral therapy during pregnancy have high rates of dropout, particularly after delivery. We aimed to identify challenges to postpartum retention in care under Option B+, which expands antiretroviral therapy access to all HIV-positive pregnant women regardless of CD4 count. Methodology:We performed 2 semi-structured interviews (SSI, n = 50) and 1 focus group discussion (n = 8) with HIV-positive women at Witkoppen Health and Welfare Centre, a primary care facility in Johannesburg, South Africa, that is one of the only clinics offering Option B+ in South Africa. Results:Fifty women completed the SSI before delivery, and 48 (96%) completed the second SSI within 3 months of delivery. Median age was 28 years (interquartile range: 26–34); most women worked (62%) or had worked in the previous year (18%). Postpartum women attending HIV care perceived that barriers to HIV care after delivery among other women included the belief that mothers care more about the babys health than their own (29.2%, 14/48), women were “ignorant” or “irresponsible” (16.7%, 8/48), negative clinic staff treatment (12.5%, 6/48), and denial or lack of disclosure of HIV status (10.4% each, 5/48). Experienced barriers included lack of money (18.0%, 9/50), work conflict (6.0%, 3/50), and negative staff treatment (6.0%, 3/50). During the focus group discussion, 3 main themes emerged: conflict with work commitment, negative treatment from health-care workers, and lack of disclosure related to stigma. Conclusions:We identified a complex set of interconnected barriers to retaining postpartum women in HIV care under Option B+, including structural, personal, and societal barriers. The importance of postpartum HIV care for the mothers own health must be embraced by health-care workers and public health programs.

Progression and regression of premalignant cervical lesions in HIV-infected women from Soweto: a prospective cohort.

Objective:To ascertain progression and regression of cervical dysplasia in HIV-infected women in Soweto. Design:Prospective cohort. Methods:Women attending an HIV wellness clinic were offered cervical smears as part of care; smears were assessed using the Bethesda system. Those with high-grade lesions or worse were referred for colposcopy. Progression analyses included women with at least two smears at least 5.5 months apart. Hazard ratios were used to ascertain predictors of progression. Results:Two thousand, three hundred and twenty-five women had a baseline smear; their median age and CD4 cell count was 32 years and 312 cells/μl, respectively; 17% were taking highly active antiretroviral therapy (HAART); 62, 20 and 14% had normal, low-grade squamous intraepithelial lesions (LSIL) or high-grade squamous intraepithelial lesions (HSIL), respectively. Of those with baseline normal or LSIL smears, 1074 had another smear; progression from normal to LSIL was 9.6/100 person-years (95% CI 8.3–11.1) and progression from normal or LSIL to HSIL was 4.6/100 person-years (95% CI 3.9–5.5). Of 225 women with LSIL at baseline and at least one subsequent smear at least 11.5 months later, 44.0% regressed to normal (21.2/100 person-years (95% CI 17.5–25.7)). Multivariate models suggested increasing risk for progression in women with CD4 cell count below 500 cells/μl and HAART may reduce the risk of progression [adjusted hazard ratio (aHR) 0.72 (0.52–0.99)]. Conclusion:HIV-infected women have high rates of prevalent and incident HSIL and LSIL with relatively low risk of regression to normal from LSIL. HAART appears to protect against progression. Our findings suggest cervical screening intervals should be less than 10 years – irrespective of age in women with CD4 cell counts below 500 cells/μl.

The immediate effect of the Same-Sex Marriage Prohibition Act on stigma, discrimination, and engagement on HIV prevention and treatment services in men who have sex with men in Nigeria: analysis of prospective data from the TRUST cohort

BACKGROUND In January, 2014, the Same-Sex Marriage Prohibition Act was signed into law in Nigeria, further criminalising same-sex sexual relationships. We aimed to assess the immediate effect of this prohibition act on stigma, discrimination, and engagement in HIV prevention and treatment services in men who have sex with men (MSM) in Nigeria. METHODS The TRUST cohort study uses respondent-driven sampling to assess the feasibility and effectiveness of engagement of MSM in HIV prevention and treatment services at a clinical site located with a community-based organisation trusted by the MSM community. TRUST is a prospective implementation research cohort of MSM (≥16 years) in Abuja, Nigeria. We compared HIV clinical outcomes and stigma, including fear and avoidance of health care, across baseline and quarterly visits before and after implementation of the the Same-Sex Marriage Prohibition Act. Outcomes assessed were measures of stigma and discrimination, loss to follow-up, antiretroviral therapy status, and viral load. We compared outcomes before and after the legislation with χ2 statistics, and estimated incident stigma-related events and loss to follow-up with Poisson regression. FINDINGS Between March 19, 2013, and Aug 7, 2014, 707 MSM participated in baseline study procedures, contributing to 756 before legislation (prelaw) and 420 after legislation (postlaw) visits. Reported history of fear of seeking health care was significantly higher in postlaw visits than in prelaw visits (n=161 [38%] vs n=187 [25%]; p<0・0001), as was avoidance of health care (n=118 [28%] vs n=151 [20%]; p=0・001). In incidence analyses, of 192 MSM with follow-up data and no history of an event at baseline, reported fear of seeking health care was higher in the postlaw than the prelaw period (n=144; incidence rate ratio 2・57, 95% CI 1・29–5・10; p=0・007); loss to follow-up and incident healthcare avoidance were similar across periods. Of the 161 (89%) of 181 HIV-infected MSM with HIV viral loads available, those who had disclosed sexual behaviour with a health-care provider were more often virally suppressed at baseline than those with no previous disclosure (18 [29%] of 62 vs 13 [13%] of 99 men; p=0・013). INTERPRETATION These analyses represent individual-level, quantitative, real-time prospective data for the health-related effects resulting from the enactment of legislation further criminalising same-sex practices. The negative effects of HIV treatment and care in MSM reinforce the unintended consequences of such legislation on global goals of HIV eradication. Strategies to reach MSM less likely to engage in HIV testing and care in highly stigmatised environments are needed to reduce time to HIV diagnosis and treatment.

Implementation of a safer conception service for HIV-affected couples in South Africa

Objective:To describe the development and implementation of a safer conception service in a resource-limited setting. Methods:Qualitative work to inform the design of a safer conception service was conducted with clients and providers at Witkoppen Health and Welfare Centre, a primary health center in Johannesburg, South Africa. Services began in July 2013 for HIV-affected participants planning conception within 6 months and included counseling about timed unprotected intercourse and home-based self-insemination, early initiation of combined antiretroviral therapy (cART) for HIV-infected individuals, pre-exposure prophylaxis for HIV-uninfected partners and circumcision for men. Participants were enrolled into an implementation science study evaluating method uptake, acceptability, and pregnancy and HIV transmission outcomes. Results:Findings to-date from 51 qualitative participants and 128 clinical cohort participants (82 women and 46 men, representing 82 partnerships) are presented. All men were accompanied by female partners, whereas 56% of women attended with their male partner. Fifteen of the 46 couples (33%) were in confirmed serodiscordant relationships; however, of the 36 additional women attending alone, 56% were unaware of their partners’ HIV status or believed them to be HIV-uninfected. The majority of the HIV-infected women (86%) and men (71%) were on cART at enrollment; however, only 47% on cART were virally suppressed. Timed unprotected intercourse, self-insemination and cART were common choices for participants; few elected pre-exposure prophylaxis. Conclusions:Lessons learned from early implementation demonstrate feasibility of safer conception services; however, reaching discordant couples, cART-naïve infected partners, and men remain challenges. Creating demand for safer conception services among those at highest risk for HIV transmission is necessary.

Sexual Violence, Condom Negotiation, and Condom Use in the Context of Sex Work: Results From Two West African Countries

Background:Female sex workers (FSWs) are vulnerable to violence within and beyond the workplace. Violence is associated with increased burden of HIV, possibly explained through physiologic or behavioral causal pathways. These analyses sought to determine the relationship between lifetime sexual violence with unprotected, condomless vaginal intercourse (UVI) among FSWs in West Africa. Methods:FSWs (aged ≥18 years) were recruited into a cross-sectional study through respondent-driven sampling in two West African countries, Togo and Burkina Faso. A total of 1380 participants were enrolled from January to July 2013, and completed a sociobehavioral questionnaire and HIV testing. Measures included sex work history, lifetime experiences of violence victimization, sexual practices, and UVI (past month). Crude and adjusted robust log binomial regression was conducted to estimate prevalence ratios (PrR) as a measure of association between UVI with clients and the primary exposure, forced sex. Results:Self-reported lifetime physical abuse (47.3%), forced sex (33.0%), and any violence (57.9%) were common. Almost one-quarter (23.9%) reported recent UVI with clients. History of forced sex was independently associated with recent UVI with clients [vs. none, adjusted PrR: 1.49; 95% confidence interval (CI): 1.18 to 1.88], with evidence of partial mediation by difficult condom negotiation with regular (aPrR: 1.83; 95% CI: 1.43 to 2.34) and new clients (aPrR: 1.60; 95% CI: 1.13 to 2.29). Discussion:These data demonstrate the significant relationship between sexual violence experienced by FSWs and unprotected sex with clients. Comprehensive interventions reducing vulnerabilities to violence combined with improved condom negotiation are needed to address the complex influences of condom use during sex work as a means of ultimately lowering HIV acquisition and transmission.

Evaluating respondent-driven sampling as an implementation tool for universal coverage of antiretroviral studies among men who have sex with men living with HIV.

Introduction:The TRUST model based on experimental and observational data posits that integration of HIV prevention and universal coverage of antiretroviral treatment at a trusted community venue provides a framework for achieving effective reduction in HIV-related morbidity and mortality among men who have sex with men (MSM) living with HIV, as well as reducing HIV incidence. The analyses presented here evaluate the utility of respondent-driven sampling as an implementation tool for engaging MSM in the TRUST intervention. Methods:The TRUST integrated prevention and treatment model was established at a trusted community center serving MSM in Abuja, Nigeria. Five seeds have resulted in 3–26 waves of accrual between March 2013 and August 2014, with results presented here characterizing HIV burden and engagement in HIV care for 722 men across study recruitment waves. For analytic purposes, the waves were collapsed into 5 groups: 4 equally spaced (0–4, 5–9, 10–14, and 15–19) and 1 ranging from the 20th to the 26th wave with significance assessed using Pearson &khgr;2 test. Results:In earlier waves, MSM were more likely to have reported testing for HIV (82.9% in waves 0–4, 47.7% in waves 20–26; P < 0.01). In addition, biologically confirmed HIV prevalence decreased from an average of 59.1% to 42.9% (P < 0.05) in later waves. In earlier waves, about 80% of participants correctly reported their HIV status as compared with less than 25% in the later waves (P < 0.01). Finally, participants reporting being on ART decreased from 50% to 22.2% in later waves (P < 0.01). Conclusions:Implementation science studies focused on demonstrating impact of universal HIV treatment programs among people living with HIV necessitate different accrual methods than those focused on preventing HIV acquisition. Here, respondent-driven sampling was shown to be an efficient method for reaching marginalized populations of MSM living with HIV in Nigeria, and engaging them in universal HIV treatment services.

Mothers who sell sex: a potential paradigm for integrated HIV, sexual, and reproductive health interventions among women at high risk of HIV in Burkina Faso.

Background:Antenatal care is a point of entry into the health system for women across Africa and may facilitate the uptake of HIV services among female sex workers (FSWs). This study aimed to evaluate the determinants of motherhood among FSWs, their sexual risks, and their engagement in health care. Methods:A cross-sectional study was conducted from January to July 2013 among FSWs in Ouagadougou and Bobo-Dioulasso, Burkina Faso. The study used respondent-driven sampling for HIV testing and behavioral data collection. Predictors of motherhood and the association of motherhood and sex work dynamics were assessed separately using logistic regression. Results:Of the 696 women enrolled, the majority of participants (76.6%, n = 533) had at least 1 biological child. Mothers were more likely to have a nonpaying partner [adjusted odds ratio (aOR), 1.73; 95% confidence interval (CI): 1.20 to 2.49], and significantly less likely to currently desire to conceive (aOR, 0.21; 95% CI: 0.13 to 0.33). Motherhood was predictive of having reduced condomless vaginal or anal sex with a new client [age-adjusted odds ratio (aaOR), 0.80; 95% CI: 0.65 to 0.97] in the past 30 days, and increased condomless vaginal or anal sex with a nonpaying partner (aaOR, 1.49; 95% CI: 1.13 to 1.96). Motherhood was prognostic of a higher likelihood of ever being tested for HIV (aaOR, 1.89; 95% CI: 1.55 to 2.31). Motherhood was predictive of reporting limited difficulty when accessing health services (aaOR, 0.15; 95% CI: 0.67 to 0.34). Conclusions:Motherhood is common among FSWs. The results indicate that FSWs who are mothers may have more exposure to health care because of seeking antenatal/perinatal services, presenting important opportunities for inclusion in the HIV continuum of care and to prevent vertical transmission.

Representation of women and pregnant women in HIV research: a limited systematic review.

Background HIV-related outcomes may be affected by biological sex and by pregnancy. Including women in general and pregnant women in particular in HIV-related research is important for generalizability of findings. Objective To characterize representation of pregnant and non-pregnant women in HIV-related research conducted in general populations. Data Sources All HIV-related articles published in fifteen journals from January to March of 2011. We selected the top five journals by 2010 impact factor, in internal medicine, infectious diseases, and HIV/AIDS. Study Eligibility Criteria HIV-related studies reporting original research on questions applicable to both men and women of reproductive age were considered; studies were excluded if they did not include individual-level patient data. Study appraisal and synthesis methods. Articles were doubly reviewed and abstracted; discrepancies were resolved through consensus. We recorded proportion of female study participants, whether pregnant women were included or excluded, and other key factors. Results In total, 2014 articles were published during this period. After screening, 259 articles were included as original HIV-related research reporting individual-level data; of these, 226 were determined to be articles relevant to both men and women of reproductive age. In these articles, women were adequately represented within geographic region. The vast majority of published articles, 183/226 (81%), did not mention pregnancy (or related issues); still fewer included pregnant women (n=33), reported numbers of pregnant women (n=19), or analyzed using pregnancy status (n=9). Limitations Data were missing for some key variables, including pregnancy. The time period over which published works were evaluated was relatively short. Conclusions and implications of key findings. The under-reporting and inattention to pregnancy in the HIV literature may reduce policy-makers’ ability to set evidence-based policy around HIV/AIDS care for pregnant women and women of child-bearing age.

Engagement in the HIV care cascade and barriers to antiretroviral therapy uptake among female sex workers in Port Elizabeth, South Africa: findings from a respondent-driven sampling study

Background Female sex workers (FSWs) are disproportionately affected by HIV, even in the context of broadly generalised HIV epidemics such as South Africa. This has been observed in spite of the individual and population-level benefits of HIV treatment. We characterise the HIV care cascade among FSWs and relationships with antiretroviral therapy (ART) use. Methods FSWs ≥18 years were recruited through respondent-driven sampling into a cross-sectional study in Port Elizabeth, South Africa. Participants completed questionnaires and received HIV and syphilis testing; CD4 counts were assessed among women living with HIV. Engagement in the HIV care cascade is described, and correlates of self-reported ART use among treatment-eligible previously diagnosed FSWs were estimated using robust Poisson regression. Results Between October 2014 and April 2015, 410 FSWs participated in study activities. Overall, 261/410 were living with HIV (respondent-driven sampling-weighted prevalence 61.5% (95% bootstrapped CI 54.1% to 68.0%)). Prior diagnosis of HIV was relatively high (214/261, 82%); however, ART coverage among FSWs living with HIV was 39% (102/261). In multivariate analyses, FSWs were less likely to be on ART if they had not disclosed their HIV status to non-paying partners (adjusted prevalence ratio (aPR) 0.43, 95% CI 0.22 to 0.86, where the reference is FSWs without non-paying partners), and also if they engaged in mobile healthcare services (aPR 0.71, 95% CI 0.57 to 0.89). Conclusions HIV testing and awareness of HIV status were high, but substantial losses in the cascade occur at treatment initiation. Given that FSWs engaged in mobile HIV testing and peer education programmes have unmet HIV treatment needs, models of decentralised treatment provision such as mobile-based ART care should be evaluated.
