Profiles of Sexual Economic Exchanges among Women in Kisumu, Kenya
Sexual economic exchanges, including sex work and transactional sex, have been consistently associated with HIV acquisition among young women in sub-Saharan Africa. Heterogeneity in HIV vulnerability across overlapping types of sexual economic exchange has not been sufficiently explored, limiting appropriate and effective linkage to prevention interventions. From January 2017 to May 2018, cross-sectional data were captured at screening for entry …
HIV Knowledge, Information Sources, and Perceived Risk among Reproductive-Aged Individuals in Kisumu, Kenya
HIV incidence and its associated factors among young adults with multiple sexual partners in Maputo, Mozambique
Our findings may inform inclusion criteria for upcoming clinical trials of HIV prevention interventions, including vaccine candidates, which may prioritize enrollment of MSM, people with more than three sexual partners, and people with sexual partners who are living with HIV. These same populations are in need of further intervention to reduce HIV incidence
Temporal trends in self-reported HIV stigma and association with adherence and viral suppression in the African Cohort Study
HIV stigma is a major barrier to HIV care and treatment among people living with HIV (PLWH). Evidence suggests that expansion in antiretroviral therapy (ART) may reduce stigma. However, there are limited longitudinal studies examining temporal trends in HIV stigma in sub-Saharan Africa in the Undetectable = Untransmittable (U = U) era. We longitudinally assessed temporal trends in self-reported experienced stigma and the association of experience…
Perinatal Depressive Symptoms and Viral Non-suppression Among a Prospective Cohort of Pregnant Women Living with HIV in Nigeria, Kenya, Uganda, and Tanzania
Depression is common during pregnancy and is associated with reduced adherence to HIV-related care, though little is known about perinatal trajectories of depression and viral suppression among women living with HIV (WLHV) in sub-Saharan Africa. We sought to assess any association between perinatal depressive symptoms and viral non-suppression among WLWH. Depressive symptomatology and viral load data were collected every 6 months from WLWH enroll…
Prevalence and predictors of food insecurity among people living with and without HIV in the African Cohort Study
Objective: We determined the prevalence and identified predictors of food insecurity in four African countries. Design: Cross-sectional analyses at study enrolment. Setting: From January 2013 to March 2020, people living with HIV (PLWH) and without HIV were enrolled at twelve clinics in Kenya, Uganda, Tanzania and Nigeria. Participants: Participants reporting not having enough food to eat over the past 12 months or receiving Results: 1694/3496 pa…
Factors associated with sexually transmitted infections among care-seeking adults in the African Cohort Study
Prevalence of STIs varied by site with young people and females most at risk for STIs. Mental health is a potential target area for intervention
Hepatitis and tuberculosis testing are much less common than HIV testing among adults in Kisumu, Kenya
Prior HIV testing was common among study participants and most had been tested within the past year but testing for tuberculosis and viral hepatitis was far less common. HIV testing gaps exist for males and those with lower levels of education. HIV testing infrastructure could be leveraged to increase access to testing for other endemic infectious diseases
East African HIV care
PLWH had high prevalence of depression on the CESD. Diverse depression symptoms were independently associated with increases in viral load, underscoring the need for comprehensive treatment of depression
