Victims and Perpetrators of Intimate Partner Violence Among Sexually Active Youth in a Community With a High HIV Prevalence in Western Kenya.

BACKGROUND: Physical intimate partner violence (IPV) is an important risk factor for sexually transmitted infections, including HIV. We set out to determine the prevalence and correlates of IPV among youth aged 15 to 24 years - in a community with a high HIV prevalence - with a view to recommending strategies to address IPV. METHODS: We analysed data from an HIV seroprevalence survey, which included participants aged 13 years and above and was conducted between November 2012 and December 2014 in Gem Subcounty, Siaya County, Western Kenya. Participants between 15 and 24 years old (youth) were described as "perpetrators of IPV" if they had done anything to physically hurt their sexual partners in the previous year and as "victims of IPV" if they had been physically hurt by a sexual partner in the same timeframe. Logistic regression was used to determine factors associated with being either a victim or perpetrator of IPV. RESULTS: Of 1,957 participants included in the analysis, 142 (7%) were victims of IPV, and 77 (4%) were perpetrators of IPV. Victims were likely to be women (adjusted odds ratio [AOR] 7.9; 95% CI, 3.6 to 17.5), in a relationship or married (AOR 3.1; 95% CI, 1.8 to 5.4), and to have had multiple lifetime sexual partners. Victims of IPV were also more likely than not to have been subjected to sexual violence in the past (AOR 1.9; 95% CI, 1.0 to 3.4) or recently (AOR 3.9; 95% CI, 2.2 to 6.8). Perpetrators were likely to be men (AOR 2.1; 95% CI, 1.2 to 3.7), with 5 or more lifetime sexual partners (AOR 2.8; 95% CI, 1.3 to 6.3), and to have committed sexual violence recently (AOR 2.9; 95% CI, 1.1 to 7.7). CONCLUSION: There was a high prevalence of IPV among sexually active youth in this rural community. Study participants were recurrent victims or perpetrators and reported behaviours that put them at risk of HIV acquisition. Health programmes should screen for IPV victims and perpetrators using identified characteristics. Existing policies regarding gender-based violence should be enforced, and future research should focus on the impact of IPV prevention programmes.

Community-based evaluation of PMTCT uptake in Nyanza Province, Kenya.

INTRODUCTION: Facility-based assessments of prevention of mother-to-child HIV transmission (PMTCT) programs may overestimate population coverage. There are few community-based studies that evaluate PMTCT coverage and uptake. METHODS: During 2011, a cross-sectional community survey among women who gave birth in the prior year was performed using the KEMRI-CDC Health and Demographic Surveillance System in Western Kenya. A random sample (n = 405) and a sample of women known to be HIV-positive through previous home-based testing (n = 247) were enrolled. Rates and correlates of uptake of antenatal care (ANC), HIV-testing, and antiretrovirals (ARVs) were determined. RESULTS: Among 405 women in the random sample, 379 (94%) reported accessing ANC, most of whom (87%) were HIV tested. Uptake of HIV testing was associated with employment, higher socioeconomic status, and partner HIV testing. Among 247 known HIV-positive women, 173 (70%) self-disclosed their HIV status. Among 216 self-reported HIV-positive women (including 43 from the random sample), 82% took PMTCT ARVs, with 54% completing the full antenatal, peripartum, and postpartum course. Maternal ARV use was associated with more ANC visits and having an HIV tested partner. ARV use during delivery was lowest (62%) and associated with facility delivery. Eighty percent of HIV infected women reported having their infant HIV tested, 11% of whom reported their child was HIV infected, 76% uninfected, 6% declined to say, 7% did not recall; 79% of infected children were reportedly receiving HIV care and treatment. CONCLUSIONS: Community-based assessments provide data that complements clinic-based PMTCT evaluations. In this survey, antenatal HIV test uptake was high; most HIV infected women received ARVs, though many women did not self-disclose HIV status to field team. Community-driven strategies that encourage early ANC, partner involvement, and skilled delivery, and provide PMTCT education, may facilitate further reductions in vertical transmission.

Shame, guilt, and stress: Community perceptions of barriers to engaging in prevention of mother to child transmission (PMTCT) programs in western Kenya.

While global scale-up of prevention of mother-to-child transmission of HIV (PMTCT) services has been expansive, only half of HIV-infected pregnant women receive antiretroviral regimens for PMTCT in sub-Saharan Africa. To evaluate social factors influencing uptake of PMTCT in rural Kenya, we conducted a community-based, cross-sectional survey of mothers residing in the KEMRI/CDC Health and Demographic Surveillance System (HDSS) area. Factors included referrals and acceptability, HIV-related stigma, observed discrimination, and knowledge of violence. Chi-squared tests and multivariate regression analyses were used to detect stigma domains associated with uptake of PMTCT services. Most HIV-positive women (89%) reported blame or judgment of people with HIV, and 46% reported they would feel shame if they were associated with someone with HIV. In multivariate analyses, shame was significantly associated with decreased likelihood of maternal HIV testing (Prevalence Ratio 0.91, 95% Confidence Interval 0.84-0.99), a complete course of maternal antiretrovirals (ARVs) (PR 0.73, 95% CI 0.55-0.97), and infant HIV testing (PR 0.86, 95% CI 0.75-0.99). Community perceptions of why women may be unwilling to take ARVs included stigma, guilt, lack of knowledge, denial, stress, and despair or futility. Interventions that seek to decrease maternal depression and internalization of stigma may facilitate uptake of PMTCT.

Geographic distribution of HIV stigma among women of childbearing age in rural Kenya.

OBJECTIVE(S): HIV stigma is considered to be a major driver of the HIV/AIDS pandemic, yet there is a limited understanding of its occurrence. We describe the geographic patterns of two forms of HIV stigma in a cross-sectional sample of women of childbearing age from western Kenya: internalized stigma (associated with shame) and externalized stigma (associated with blame). DESIGN: Geographic studies of HIV stigma provide a first step in generating hypotheses regarding potential community-level causes of stigma and may lead to more effective community-level interventions. METHODS: Spatial regression using generalized additive models and point pattern analyses using K-functions were used to assess the spatial scale(s) at which each form of HIV stigma clusters, and to assess whether the spatial clustering of each stigma indicator was present after adjustment for individual-level characteristics. RESULTS: There was evidence that externalized stigma (blame) was geographically heterogeneous across the study area, even after controlling for individual-level factors (P=0.01). In contrast, there was less evidence (P=0.70) of spatial trend or clustering of internalized stigma (shame). CONCLUSION: Our results may point to differences in the underlying social processes motivating each form of HIV stigma. Externalized stigma may be driven more by cultural beliefs disseminated within communities, whereas internalized stigma may be the result of individual-level characteristics outside the domain of community influence. These data may inform community-level interventions to decrease HIV-related stigma, and thus impact the HIV epidemic.
