  • Predictive and concurrent validity of caregiver reported early childhood development assessments

    Open AccessJonathan Seiden, Dana Charles Mccoy et al.ARTICLEPLOS Global Public Health2026

    Many directly assessed and caregiver-reported measures of early childhood development (ECD) are used to monitor outcomes and evaluate interventions in low- and middle-income countries (LMICs). Many assessments of ECD for children 0–3 years old have robust psychometric properties, but relatively little is known about their ability to predict later developmental and learning outcomes. To address questions about predictive and concurrent validity, w…

  • Longitudinal Patterns of Adherence to Oral HIV Pre-Exposure Prophylaxis Among At-Risk Women in Tanga, Tanzania

    Open AccessWigilya P Mikomangwa, Emmy Metta et al.ARTICLEAIDS and Behavior2026

    There is scarcity of evidence on the changes over time of adherence to oral HIV pre-exposure prophylaxis (PrEP) among female sex workers. Therefore, we assessed the changes of adherence to PrEP over 12 months and influencing factors for suboptimal adherence and explored strategies to optimize adherence to oral PrEP among female sex workers in Tanzania. Convergence analysis was conducted involving 313 respondent driven sampled participants in the …

  • Low-dose calcium supplementation during pregnancy in low and middle-income countries

    Open AccessHappiness Pius Saronga, Pratibha Dwarkanath et al.ARTICLEPLOS Global Public Health2025

    Calcium supplementation during pregnancy can reduce the risk of preeclampsia and preterm birth. Few countries have implemented WHO-recommended high-dose calcium supplementation (1500–2000mg/day), due to adherence and cost concerns. However, low-dose calcium supplementation (one 500mg tablet daily) has recently been shown to be similarly efficacious as high-dose supplementation. We assessed the cost-effectiveness of low-dose calcium supplementatio…

  • Human capital and lifetime income gains of scaling-up small-quantity lipid nutrient supplements among children under 2 years

    Open AccessNandita Perumal, Goodarz Danaei et al.ARTICLEPLOS Global Public Health2025

    Undernutrition in early childhood is associated with adverse health and developmental outcomes later in life and remains a persistent global public health problem. Providing small-quantity lipid nutrient supplements (SQ-LNS) to children aged 6-24 months improves child growth and neurodevelopmental outcomes, but the potential long-term benefits to human capital have not been previously estimated. We estimated the potential returns to schooling and…

    Open AccessNazia Binte Ali, Arjumand Rizvi et al.ARTICLEMaternal and Child Nutrition2025

    The effect of community-based multi-input interventions that promote health, nutrition, and development on childhood infections, and the pathways that explain these effects remain unclear. We conducted a secondary analysis of a factorial-designed clustered randomized controlled trial (N = 1489) conducted in rural Pakistan to estimate the effects of responsive stimulation and enhanced nutrition (responsive feeding and multiple micronutrient powder…

  • I Stopped to Prove them Wrong

    Open AccessWigilya P Mikomangwa, Emmy Metta et al.ARTICLEAIDS and Behavior2025

    High discontinuation of pre-exposure prophylaxis (PrEP) among high-risk women undermines its effectiveness. However, there is limited evidence on the reasons for PrEP discontinuation among female sex workers in sub-Saharan Africa. Exploring population-specific reasons for PrEP discontinuation will guide the design of client-centered strategies. Thus, we explored the reasons for PrEP discontinuation among female sex workers in Tanzania using mixed…

  • Experiences, acceptability and barriers to calcium supplementation during pregnancy in Dar es Salaam, Tanzania

    Open AccessEmmy Metta, Emmy O Metta et al.ARTICLEMaternal and Child Nutrition2024

    Calcium supplementation in pregnancy is recommended in contexts with low dietary calcium intake to reduce the risk of pre-eclampsia and its complications. The World Health Organisation suggested high-dose calcium supplementation (1500-2000 mg/day), divided into three doses and taken at different times from daily iron-folic supplements. We conducted a mixed methods evaluation study to assess experiences, acceptability and barriers to high-dose cal…

  • Facility-based care for moderately low birthweight infants in India, Malawi, and Tanzania

    Open AccessKatherine E A Semrau, Rana R Mokhtar et al.ARTICLEPLOS Global Public Health2023

    Globally, increasing rates of facility-based childbirth enable early intervention for small vulnerable newborns. We describe health system-level inputs, current feeding, and discharge practices for moderately low birthweight (MLBW) infants (1500- 10% less than their birthweight; 18.8% of infants were discharged with weights below facility-specific policy [1800g in India, 1500g in Malawi, and 2000g in Tanzania]. Based on descriptive analysis, we f…

  • Safe infant feeding in healthcare facilities

    Open AccessBrooke A Caruso, Uriel Paniagua et al.ARTICLEPLOS Global Public Health2023

    Infants need to receive care in environments that limit their exposure to pathogens. Inadequate water, sanitation, and hygiene (WASH) environments and suboptimal infection prevention and control practices in healthcare settings contribute to the burden of healthcare-associated infections, which are particularly high in low-income settings. Specific research is needed to understand infant feeding preparation in healthcare settings, a task involvin…

  • The impact of a community health worker intervention on uptake of antenatal care

    Open AccessMathilda Regan, Chao Cheng et al.ARTICLEHealth Policy and Planning2023

    The provision of high-quality antenatal care (ANC) is important for preventing maternal and newborn mortality and morbidity, but only around half of pregnant women in Tanzania attended four or more ANC visits in 2019. Although there is emerging evidence on the benefit of community health worker (CHW) interventions on ANC uptake, few large-scale pragmatic trials have been conducted. This pragmatic cluster-randomized trial, implemented directly thr…
