Relationship Power, Partner Risk Characteristics, and Recent Intimate Partner Violence Among Adolescent Girls and Young Women in a High HIV Incidence Setting in Kenya
Adolescent girls and young women (AGYW) in sub-Saharan Africa face intersecting risks of HIV and intimate partner violence (IPV). Although pre-exposure prophylaxis (PrEP) expands HIV prevention options, its use is often constrained by imbalanced relationship power and male partner behaviors. We used baseline data from the Tu’Washindi na PrEP cluster randomized trial to describe PrEP use, relationship dynamics and identify attributes associated wi…
PrEP Use Willingness and Perceptions Among Young Female Sex Workers in Kisumu, Kenya
Female sex workers (FSW) are disproportionately burdened with HIV. Pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV transmission, yet determinants of willingness to use PrEP among young FSW is less understood. We assessed factors associated with willingness to use PrEP, using data from a cross-sectional study on PrEP adherence strategies, among HIV-negative FSW aged 18–24 years living in Kisumu City, Kenya. We characterized d…
Comparing comprehension of consent document between adolescent girls and caregivers of adolescents in Siaya County, Kenya
Despite their vulnerability, adolescents are often excluded from health research due to ethical concerns about research with minors, especially in low-income regions like Sub-Saharan Africa. We enrolled adolescent girls aged 15–17 years and caregivers of girls of the same age. Using a 25-question Comprehension Score Sheet, we applied a quantitative approach to compare the comprehension of informed consent of 33 adolescent girls and 41 caregivers …
Health promotion messaging reduces HIV risk behaviours and improves repeat testing among adolescent girls and young women in Kenya
Adolescents and young people in sub-Saharan Africa account for about a third of persons newly diagnosed with HIV. Health communication, through mobile health (mHealth) can improve access to sexual and reproductive health information, health services and reduce risky sexual behaviours among adolescents and young people. We assessed the impact of a health promotion messaging intervention on the reduction of risky sexual behaviours among HIV-negativ…
Saving for a rainy day
Financial insecurity pushes female sex workers into risky sexual transactions. We piloted an economic empowerment intervention among female sex workers in Kenya to test if they could save part of their income from which to make withdrawals to avoid risky sexual encounters. We enrolled female sex workers and randomised half to the intervention arm, who were given instructions on how to save and withdraw money through a mobile platform, and half to…
Shifting reasons for older men remaining uncircumcised
Voluntary medical male circumcision (VMMC) reduces men’s risk of acquiring Human immunodeficiency virus (HIV) through vaginal sex. However, VMMC uptake remains lowest among Kenyan men ages 25–39 years among whom the impact on reducing population-level HIV incidence was estimated to be greatest at the start of the study in 2014. We conducted a pre- and post-intervention survey as part of a cluster randomized controlled trial to determine the effec…
Facility characteristics preferred by older men seeking medical male circumcision services in Kenya
Primary healthcare facilities are central to the implementation of voluntary medical male circumcision (VMMC) as points of access to integrated health services in line with the Kenya AIDS Strategic Framework II (2020/21-2024/25). Knowledge of factors that explain men's uptake of VMMC and sexual health services at these facilities and preferences of where to get the services remain poorly understood. Using qualitative methodologies, we examined fa…
Jitegemee (rely on yourself)
A savings intervention for and by FSW was highly acceptable and feasible. Involving end-users in the design process is likely to result in greater economic security among FSW and lower engagement in higher risk transactional sex
Early infant male circumcision
Introduction : Traditional male circumcision (TMC) inculcates masculine-dominance norms in young men. Early infant male circumcision (EIMC) and medical male circumcision (MMC) can potentially minimise these adverse gender norms. We explored the perceptions about EIMC and MMC among communities practising TMC in Kenya. Method: We conducted focus group discussions with men and women and councils of elders, and key informant interviews with tradition…
I didn’t support PrEP because I didn’t know what it was ”
The HIV infection rate is higher among adolescent girls and young women (AGYW) in Africa than men in the same age range. Pre-exposure prophylaxis (PrEP) can be used by women discreetly; however, for most AGYW, male partner approval is desired. We explored PrEP use in the context of relationship violence and power dynamics through focus group discussions and support club sessions with AGYW, in-depth interviews and male sensitisation sessions with …
Preexposure Prophylaxis for HIV Infection among African Women
BACKGROUND: Preexposure prophylaxis with antiretroviral drugs has been effective in the prevention of human immunodeficiency virus (HIV) infection in some trials but not in others. METHODS: In this randomized, double-blind, placebo-controlled trial, we assigned 2120 HIV-negative women in Kenya, South Africa, and Tanzania to receive either a combination of tenofovir disoproxil fumarate and emtricitabine (TDF-FTC) or placebo once daily. The primary…
