A comparison of all-cause and HIV cause-specific mortality among children under 5 years of age before and during Covid-19 in Kenya, 2018–2022
The impact of the COVID-19 pandemic on pediatric mortality, including measures to ensure continuity of HIV care, is not well described in Kenya. We evaluated causes of death (COD) among decedents under 5 years of age both before and during the COVID-19 pandemic in Kenya. We analyzed Child Health and Mortality Prevention Surveillance (CHAMPS) data collected in February 2018–March 2022. We describe the proportional contribution of specific conditio…
Assessing heat exposure and its effects on farmer health, harvest yields, and nutrition
Rising temperatures in Africa present an increasing threat to agricultural productivity and public health, particularly among subsistence farming communities reliant on rain-fed agriculture. Heat exposure can impair farmers' work capacity, disrupt harvests, and heighten health risks, especially for young children vulnerable to undernutrition. The Heat to Harvest (H2H) study investigates how environmental heat exposure influences farmers' physiolo…
Because she doesn’t have a voice’. Perceptions of rejection amongst girls who have dropped out of school in rural western Kenya
Despite global commitments to girls’ education, many dropout prematurely facing health, social, and economic hardships. Using ten focus group discussions and ten in-depth interviews, this study explored issues identified as important in the lives of girls who had dropped out of school. Thematic analysis first revealed rejection as a central theme in the girls' experiences, prompting a deductive approach that identified five interrelated themes: (…
Pregnancy reporting and biases in under-five mortality in three African HDSSs
In the absence of complete civil registration and vital statistics, Health and Demographic Surveillance Systems (HDSSs) are important sources of population-based data throughout sub-Saharan Africa. However, HDSS data on the vital status of newborns are often unreliable due to omission of those who were born and died between two rounds of data collection and are therefore never enumerated. This study investigates whether pregnancy registration imp…
The effects of climatic and non-climatic factors on malaria mortality at different spatial scales in western Kenya, 2008–2019
BACKGROUND: Malaria mortality is influenced by several factors including climatic and environmental factors, interventions, socioeconomic status (SES) and access to health systems. Here, we investigated the joint effects of climatic and non-climatic factors on under-five malaria mortality at different spatial scales using data from a Health and Demographic Surveillance System (HDSS) in western Kenya. METHODS: We fitted Bayesian spatiotemporal (ze…
Widening the lens of population-based health research to climate change impacts and adaptation
Background: Climate change significantly impacts health in low-and middle-income countries (LMICs), exacerbating vulnerabilities. Comprehensive data for evidence-based research and decision-making is crucial but scarce. Health and Demographic Surveillance Sites (HDSSs) in Africa and Asia provide a robust infrastructure with longitudinal population cohort data, yet they lack climate-health specific data. Acquiring this information is essential for…
Mortality patterns over a 10-year period in Kibera, an urban informal settlement in Nairobi, Kenya, 2009–2018
Background Reliable mortality data are important for evaluating the impact of health interventions. However, data on mortality patterns among populations living in urban informal settlements are limited.Objectives To examine the mortality patterns and trends in an urban informal settlement in Kibera, Nairobi, Kenya,Methods Using data from a population-based surveillance platform we estimated overall and cause-specific mortality rates for all age …
Impact of Covid-19 lockdowns on adolescent pregnancy and school dropout among secondary schoolgirls in Kenya
INTRODUCTION: Secondary school closures aimed at limiting the number of infections and deaths due to COVID-19 may have amplified the negative sexual and reproductive health (SRH) and schooling outcomes of vulnerable adolescent girls. This study aimed to measure pandemic-related effects on adolescent pregnancy and school dropout among school-going girls in Kenya. METHODS: We report longitudinal findings of 910 girls in their last 2 years of second…
Quality of life and well-being problems in secondary schoolgirls in Kenya
Background Adolescents in sub-Saharan Africa often report low levels of quality of life (QoL) and well-being, but reliable data are limited. This study examines which sociodemographic, health, and behavioral risk factors and adverse adolescent experiences are associated with, and predictive of, QoL in Kenyan secondary schoolgirls. Methods and findings 3,998 girls at baseline in a randomised controlled trial in Siaya County, western Kenya were med…
‘You don’t have to sleep with a man to get how to survive’
In sub-Saharan Africa, girls suffer from high rates of morbidity and mortality, enduring high exposure to sexual and reproductive health harms. Staying in school helps protect girls from such harms. Focus group discussions were conducted in a rural, impoverished area of Kenya with adolescent girls participating in a 4-arm cluster randomised controlled trial, evaluating menstrual cups, cash transfer, or combined cups plus cash transfer against con…
Impact of mobile phone delivered reminders and unconditional incentives on measles-containing vaccine timeliness and coverage
INTRODUCTION: Short message service (SMS) reminders coupled with a small monetary incentive conditioned on prompt vaccination have been shown to improve first-dose measles-containing vaccine (MCV1) uptake. We assessed whether SMS reminders and unconditional monetary incentives-more amenable to programmatic implementation-can improve MCV1 uptake in Kenya. METHODS: Caregivers of eligible infants aged 6-8 months were enrolled into an individually ra…
Menstrual cups and cash transfer to reduce sexual and reproductive harm and school dropout in adolescent schoolgirls

Do Water, Sanitation and Hygiene Conditions in Primary Schools Consistently Support Schoolgirls’ Menstrual Needs? A Longitudinal Study in Rural Western Kenya
Many females lack access to water, privacy and basic sanitation-felt acutely when menstruating. Water, sanitation and hygiene (WASH) conditions in schools, such as access to latrines, water, and soap, are essential for the comfort, equity, and dignity of menstruating girls. Our study was nested within a cluster randomized controlled pilot feasibility study where nurses provided menstrual items to schoolgirls. We observed the WASH conditions of 30…
Association between internal migration and epidemic dynamics
Results suggest that structural socioeconomic issues, rather than epidemic dynamics are likely to be associated with differences in mortality risk by migrant status. Interventions aimed at improving recent migrant's access to treatment may mitigate risk
Mortality from external causes in Africa and Asia
BACKGROUND: Mortality from external causes, of all kinds, is an important component of overall mortality on a global basis. However, these deaths, like others in Africa and Asia, are often not counted or documented on an individual basis. Overviews of the state of external cause mortality in Africa and Asia are therefore based on uncertain information. The INDEPTH Network maintains longitudinal surveillance, including cause of death, at populatio…
