Longitudinal pathways between maternal depression, parenting behaviors, and early childhood development
Open AccessAlan Frost, Elissa Scherer et al.ARTICLEInternational Journal of…2025
Maternal depression is a global public health concern with far-reaching impacts on child development, yet our understanding of mechanisms remains incomplete. This study examined whether parenting mediates the association between maternal depression and child outcomes. Participants included 841 rural Pakistani mother–child dyads (50% female). Maternal depression was measured at 12 months postpartum, parenting behaviors (warmth, stimulation, and ha…

A cluster-randomized trial of client and provider directed financial interventions to align incentives with appropriate case management in private medicine retailers
Open AccessTheodoor Visser, Jeremiah Laktabai et al.ARTICLEPLOS Global Public Health2024
Malaria remains a major health priority in Nigeria. Among children with fever who seek care, less than a quarter gets tested for malaria, leading to inappropriate use of the recommended treatment for malaria; Artemisinin-based Combination Therapy (ACT). Here we test an innovative strategy to target ACT subsidies to clients seeking care in Nigeria’s private retail health sector who have a confirmed malaria diagnosis. We supported point-of-care mal…
A cluster-randomized trial of client and provider-directed financial interventions to align incentives with appropriate case management in retail medicine outlets
Open AccessJeremiah Laktabai, Emmah Kimachas et al.ARTICLEPLOS Global Public Health2024
ACTs are responsible for a substantial proportion of the global reduction in malaria mortality over the last ten years, made possible by publicly-funded subsidies making these drugs accessible and affordable in the private sector. However, inexpensive ACTs available in retail outlets have contributed substantially to overconsumption. We test an innovative, scalable strategy to target ACT-subsidies to clients with a confirmatory diagnosis. We supp…

Sauti ya Vijana (SYV; The Voice of Youth)
Open AccessDorothy E Dow, Karen E O’Donnell et al.ARTICLEAIDS and Behavior2022
Sauti ya Vijana is a mental health and life skills intervention delivered by young adult group leaders for the improvement of HIV outcomes in young people living with HIV in Tanzania. This pilot randomized controlled trial estimated exploratory intervention effectiveness compared to standard of care. YPLWH (N = 105) were randomized to receive intervention or SOC. The mean age of participants was 18.1 years and 53% were female. Mean scores on ment…
Effect of a lay counselor-delivered integrated maternal mental health and early childhood development group-based intervention in Northern Ghana

This real-world evaluation had null findings; however, post-intervention depression levels were very low in both arms (3%). Future research should examine the potential impact of women's groups on postpartum mental health more broadly with varying content
Feasibility and acceptability of a peer youth led curriculum to improve HIV knowledge in Northern Tanzania
Open AccessKalei R J Hosaka, Blandina T Mmbaga et al.ARTICLEBMC Public Health2021
This study demonstrated that a PYL curriculum to improve HIV knowledge integrated into routine adolescent HIV clinic in Tanzania was feasible, acceptable, and improved knowledge while also benefiting peer leaders, thus providing evidence to continue to support efforts to scale and sustain PYL interventions for YLWH

Correlates of early stimulation activities among mothers of children under age two in Siaya County, Kenya
Open AccessE Tammy Kim, Eunsoo Timothy Kim et al.ARTICLESocial Science & Medicine2021Cited by: 1References: 28
This study indicates that both mothers and families could benefit from availability of ECD-friendly resources such as homemade toys and children's books (particularly for low-income families), and tailored messaging to support early stimulation activities for both girl and boy children and for those prematurely-born. Local governments and community-based programs can aim to both raise awareness about the importance of early childhood development …
The contribution of grandmother involvement to child growth and development
Open AccessEsther O Chung, A K Hagaman et al.ARTICLEBMJ Global Health2020
INTRODUCTION: Early childhood interventions primarily focus on the mother-child relationship, but grandmothers are often critical in childcare in low-resource settings. Prior research is mixed on how grandmother involvement influences child outcomes and there is a paucity of research on grandmother caregiving in low-income and middle-income countries. We examined the role of grandmother involvement on child growth and development in the first 2 y…

Building resilience
Open AccessDorothy E Dow, Blandina T Mmbaga et al.ARTICLEAIDS Care2018
Despite a growing population of youth living with HIV, few interventions have been developed to address their unique mental health needs and to promote resilience. Based on our prior needs assessment, a mental health intervention, Sauti ya Vijana ( The Voice of Youth), was developed to address identified mental health needs and promote resilience. The intervention emphasized resilience strategies for identifying and coping with stressful events, …
Socioeconomic status indicators and common mental disorders
Open AccessJoanna Maselko, Lisa M Bates et al.ARTICLESSM - Population Health2017
There is growing interest in the relationship between socioeconomic status (SES), poverty, and mental health in low and middle-income countries (LMIC). However, it is not clear whether a gradient approach focused on a wider SES distribution or a binary poverty approach is more salient for mental health in LMIC. Yet this distinction has implications for interventions aimed at improving population health. We contribute to the literature by examinin…
Association between distance to nearest supermarket and provision of fruits and vegetables in English nurseries
Open AccessT Burgoine, John A Gallis et al.ARTICLEHealth & Place2017
With 796,500 places available for children in England, pre-school nurseries could serve as an important setting for population-wide dietary intervention. It is critical to understand the determinants of healthy food provision in this setting, which may include access to food stores. This study examined the association between objective, GIS-derived supermarket proximity and fruit and vegetable serving frequency, using data from 623 English nurser…
