Youth mental health has emerged as a pressing global issue. However, to advance research gaps in low-income settings, we need valid measures of common disorders. Using primary data collected five countries (Kenya, Malawi, Tanzania, Zambia, and Zimbabwe), this study aims assess the psychometric properties commonly used 10-item Center for Epidemiological Studies Depression (CES-D 10) scale among poor, disadvantaged youth populations sub-Saharan African (SSA).
We explore the impacts of Malawi's national unconditional cash transfer program targeting ultra-poor households on youth mental health. Experimental findings show that significantly improved health outcomes. Among girls in particular, reduces indications depression by about 15 percentage points. investigate contribution different possible pathways to overall impact, including education, health, consumption, caregiver's stress levels and life satisfaction, perceived social support,...
In sub-Saharan Africa, young women who engage in transactional sex (the exchange of for money or gifts) with a male partner show an elevated risk prevalent HIV infection. We analyse longitudinal data to estimate the association between and incidence.We used from cohort 2362 HIV-negative (aged 13-20 years) enrolled randomized controlled trial rural, South Africa were followed up four visits over 6 years.The effect on incident was analysed using stratified Cox proportional hazards models...
Adolescent girls and young women (AGYW) have a much higher risk of HIV infection than men the same age. One hypothesis for this disparity is AGYW are more likely to be in sexual partnerships with older HIV; however, evidence has been inconclusive.We used longitudinal data from randomized trial South Africa (HPTN 068) determined whether partner age difference associated incident AGYW.Age was examined continuously dichotomously (≥5 years). We inverse probability exposure weighted survival...
Abstract Introduction Evidence has shown that the experience of violence by a partner important influences on women's risk HIV acquisition. Using randomized experiment in northeast South Africa, we found conditional cash transfer ( CCT ) targeted to poor girls high school reduced physical intimate IPV past 12 months 34%. The purpose this analysis is understand pathways through which affects . Methods HPTN 068 was phase 3, controlled trial rural Mpumalanga province, Africa. Eligible young...
This study analyzes the short-term impact of an exogenous, positive income shock on caregivers' subjective well-being (SWB) in Malawi using panel data from 3,365 households targeted to receive Malawi's Social Cash Transfer Program that provides unconditional cash ultra-poor, labor-constrained households. The consists a cluster-randomized, longitudinal design. After baseline survey, half these village clusters were randomly selected transfer and follow-up was conducted 17 months later. We...
Evidence on cash transfer interventions for HIV prevention in adolescent girls and young women is unclear indicates that they may not work uniformly all settings. Qualitative interviews were conducted with 22 post-intervention to determine how a study (HPTN 068) South Africa was perceived influence sexual behaviours explore mechanisms these changes. Participants described the intervention motivated them increase condom use, have fewer partners, end risky relationships access testing services...
Abstract Despite the growing popularity of multidimensional poverty measurement and analysis, its use to measure impact social protection programs remains scarce. Using primary data collected for evaluation HIV Prevention Trials Network (HPTN) 068, a randomized, conditional cash transfer intervention young girls in South Africa that ran from 2011 2015, we construct an individual-level poverty, major departure standard indices household as unit analysis. We our by aggregating multiple...
As national social safety nets are expanding in Africa and globally, evidence on the impact of programs youth transitions can help guide future investment program design decisions. This paper examines effects Malawi's flagship cash transfer safe to adulthood among living households experiencing ultra-poverty. The evaluation was a cluster-randomized control trial implemented over three years using panel data aged 13 19 at baseline. Household receipt bi-monthly transfers led improvements four...
Objective: In sub-Saharan Africa, transactional sex is associated with an increased risk of HIV infection in adolescent girls and young women, but the mechanisms for this relationship remain unclear. We hypothesize that women who report may have multiple partners older partners, thereby increasing their risk. Setting: used longitudinal data from HPTN 068 trial rural South Africa where aged 13–20 were HIV-negative at enrolment (n = 2362) followed approximately annually up to 6 years. Methods:...
Poverty alleviation programs can reduce HIV incidence but may have greater impacts when combined with other psychosocial interventions. We modeled the change in among South African adolescent girls and young women (AGYW) associated combining a cash transfer (the Child Support Grant (CSG)) structural behavioral observational data from HPTN 068 study where 2328 negative AGYW (13-20 years) were followed for 4 years. In Monte Carlo simulation based on this cohort (N = 10,000), CSG receipt was...
Donor financing is increasingly relying on performance-based measures that demonstrate impact. As new technologies and interventions enter the innovation space to address global health challenges, innovators often need model their potential impact prior obtaining solid effectiveness data. Diverse stakeholders rely modeling data make key funding scaling decisions. With a lack of standardized methodology various using different strategies, we propose universal checklist be used aid in...
