“When a man is stressed, it replicates in the house”
Mental health conditions are a major public health concern in the African region, where women experience a high prevalence of maternal mental health conditions and limited access to adequate care. This issue is particularly severe among women living with HIV (WLHIV), who face a heightened risk of depression and anxiety. Despite the well-documented association between male partner-related factors and maternal/child health outcomes, their impact on…
The Linda Kizazi study
BACKGROUND: Historically, children who are HIV-exposed, uninfected (CHEU) have been found to have greater morbidity and mortality than children who are HIV-unexposed, uninfected (CHUU). To assess whether this difference persists in the era of universal antiretroviral therapy (ART), we conducted a cohort study to compare the risk of acute diarrhoea, respiratory tract infections (RTI), malaria, hospitalisation, and all-cause mortality between Kenya…
Sustainability of an evidence-based intervention supporting transition to independent care for youth living with HIV in Kenya
Integrating and sustaining evidence-based interventions (EBIs) in routine care is crucial to improving HIV treatment outcomes among youth living with HIV (YLH). However, EBIs are often not sustained post clinical trial. An Adolescent Transition Package (ATP) delivered by health care workers (HCWs) and tested in Kenya in 2021 significantly improved YLH readiness to transition to independent care. Post-trial, participating clinics could continue us…
Multiple Adverse Childhood Experiences and Maternal Mental Health Outcomes Among Kenyan Mothers With and Without HIV
Gaps and Opportunities for Strengthening In‐School Support for Youth Living With HIV
OBJECTIVES: With optimized antiretroviral treatment youth living with HIV (YLH) now spend most of their time in schools, making schools an important venue to optimize outcomes. We evaluated school support for YLH. METHODS: We conducted surveys with public secondary/high schools in 3 Kenyan counties (Nairobi, Homa Bay, and Kajiado) to determine policies and training related to HIV. Chi-squared tests and Poisson regression were used to compare poli…
“We can tell a good teacher who cares, understands, and can be confidential about it”
Introduction: Disclosure of one's HIV status to others is often difficult due to the fear of stigma. However, disclosure may facilitate receiving social support. Many youth living with HIV (YLH) are enrolled in school as better treatments have improved the health and survival of children with HIV. There is no structured process for disclosure at school for YLH and their caregivers. We sought to understand school disclosure experiences among YLH a…
Adolescent experiences, perceptions, and preferences for the process of HIV status disclosure in Kenya
Introduction: Disclosure of HIV status to adolescents living with HIV has been associated with improved treatment outcomes. However, there are limited data regarding the experiences of, perceptions of, and preferences for the process of disclosure of HIV status among adolescents and young adults living with HIV (AYLH), especially in sub-Saharan Africa. Methods: Young adults living with HIV from 20 HIV clinics in Kenya who participated in a clinic…
Simulated patient training to improve youth engagement in HIV care in Kenya
Youth living with HIV (YLHIV) report that negative interactions with health care workers (HCWs) affects willingness to return to care. This stepped wedge randomized trial evaluated effectiveness of a standardized patient actor (SP) HCW training intervention on adolescent engagement in care in Kenya. HCWs caring for YLHIV at 24 clinics received training on adolescent care, values clarification, communication, and motivational interviewing, with 7 …
Identifying HIV-exposed uninfected children and adolescents in resource-limited settings
HIV-exposed uninfected (HEU) children and adolescents are at higher risk of poor outcomes compared to HIV-unexposed children (HUU). In program settings, it is critical to understand how to identify HEU for screening services. We describe our experience identifying HEU for a neurodevelopment and mental health screening study. We recruited mothers living with HIV (MLHIV) and mothers not living with HIV (MNHIV) and enrolled their HEU or HUU children…
When they are all grown, I will tell them”
Child's age is a key consideration for parents to disclose their own HIV status to their children. While parents were open to disclosing their HIV status to their children, there is a need to address barriers including anticipated stigma, and fear that disclosure will cause distress to their children
Individual-, Interpersonal- and Institutional-Level Factors Associated with HIV Stigma Among Youth in Kenya
Risk factors for stillbirth and neonatal mortality among participants in Mobile WACh NEO pilot, a two-way SMS communication program in Kenya
Globally, 2.5 million neonates die and 2 million more are stillborn each year; the vast majority occur where access to life-saving care is limited. High quality, feasible interventions are needed to reach, educate and empower pregnant women and new mothers to improve care-seeking behaviors. Mobile WACh (Mobile solutions for Women’s and Children’s health) NEO is a human-computer hybrid mobile health (mHealth) system that allows for two-way short m…
“It’s about making adolescents in charge of their health”
The health care transition (HCT) from pediatric to adult care is a potential contributor to poor clinical outcomes among adolescents living with HIV (ALHIV). In sub-Saharan Africa (SSA), there is limited information on effective tools and processes to prepare and support ALHIV through this transition. This study elicited perspectives of policy-makers regarding barriers and facilitators to successful HCT among ALHIV in Kenya. Twenty in-depth inter…

Newly diagnosed HIV positive children
Newly diagnosed HIV positive children may be unique index cases to identify undiagnosed parents. Data was used from the Pediatric Urgent Start of HAART (NCT02063880) trial, which enrolled hospitalized, ART-naïve, HIV positive children ages 0–12 years in Kenya. Exact McNemar’s tests were used to compare proportions of mothers and fathers tested for HIV, linked to care, and on ART at baseline and 6 months. This analysis included 87 newly diagnosed …
From research to international scale-up
Stakeholder engagement between researchers, policymakers and practitioners is critical for the successful translation of research into policy and practice. The Counseling and Testing for Children at Home (CATCH) study evaluated a paediatric index case testing model, targeting the children of HIV-infected adults in care in Kenya. Researchers collaborated with stakeholders in the planning, execution and evaluation, and dissemination phases of CATCH…
Influence and involvement of support people in adolescent and young adult HIV testing
HIV incidence and mortality are high among adolescents and young adults (AYA) in sub-Saharan Africa, but testing rates are low. Understanding how support people (SP), such as peers, partners, or parents, influence AYA may improve HIV testing uptake. AYA aged 14-24 seeking HIV testing at a referral hospital in Nairobi, Kenya completed a post-test survey assessing the role of SP. Among 1062 AYA, median age was 21. Overall, 12% reported their decisi…
Pilot evaluation of a standardized patient actor training intervention to improve HIV care for adolescents and young adults in Kenya
Poor retention in HIV care remains a major problem for Adolescents and Young Adults (AYA). A Standardized Patient (SP) clinical training intervention was developed to improve healthcare worker (HCW) "adolescent-friendly" competencies in Kenya. Professional actors were trained to portray HIV-infected AYA according to standardized scripts. HCWs completed a 2-day SP training that included didactic sessions, 7 video-recorded SP encounters, and group …
Implications of Combined Exposure to Household Air Pollution and HIV on Neurocognition in Children
Air pollution exposure and HIV infection can each cause neurocognitive insult in children. The purpose of this study was to test whether children with combined high air pollution exposure and perinatal HIV infection have even greater risk of neurocognitive impairment. This was a cross-sectional study of HIV-uninfected unexposed (HUU) and HIV-infected children and their caregivers in Nairobi, Kenya. We used a detailed neuropsychological battery to…
Prevalence, perceptions, and correlates of pediatric HIV disclosure in an HIV treatment program in Kenya
Disclosure to HIV-infected children regarding their diagnosis is important as expanding numbers of HIV-infected children attain adolescence and may become sexually active. In order to define correlates of pediatric disclosure and facilitate development of models for disclosure, we conducted a cross-sectional survey of primary caregivers of HIV-1 infected children aged 6-16 years attending a pediatric HIV treatment program in Nairobi, Kenya. We co…
