Formative research in Ethiopia and Bangladesh
Background: As countries transition from implementing iron folic acid (IFA) to multiple micronutrient supplements (MMS) for pregnant women, they need accurate data on who is being reached with these interventions. The aim of our formative research in Ethiopia and Bangladesh was to design updated household survey questions, response options, and visual aids to measure coverage of prenatal micronutrient supplements. Methods: In phase I, we landscap…
The effectiveness and cost-effectiveness of cash plus interventions to prevent acute malnutrition in Somalia
Background: Acute malnutrition affects millions of children aged <5 years, as well as pregnant and lactating women globally, especially in humanitarian settings. Although cash plus interventions - cash or food transfers combined with complementary components - are widely implemented, evidence remains limited on which combinations and durations are most effective at preventing acute malnutrition. Methods: We conducted a three-arm cluster-randomise…
Levels and determinants of child wasting relapse
Background: Understanding the rates and determinants of severe acute malnutrition (SAM) relapse is crucial for stakeholders in Somalia, where evidence is limited. This study aimed to assess SAM relapse rates and associated risk factors among children discharged from outpatient therapeutic programmes (OTP) in the Bay and Hiran regions of Somalia. Methods: We conducted a prospective cohort study of 160 children aged 7-53 months discharged as recove…
Design and methodology of a cluster-randomised controlled trial on cash plus interventions for preventing child wasting in Somalia
Background: Somalia is a conflict, flood, and drought prone country with high rates of food insecurity and child wasting. Save the Children partnered with Johns Hopkins University to study the most effective and cost-effective combinations of assistance to prevent acute malnutrition among pregnant and lactating women (PLW) and children under five (CU5) in a six-month humanitarian programme. This study implemented an cluster-randomised controlled …
Assessing the correlates of wasting among children under five and their mothers in the Bay and Hiran regions of Somalia
Background: To address Somalia's high wasting burden, it is imperative to understand the country's context-specific correlates of wasting. We aimed to assess the correlates of wasting among children under five (CU5) and mothers in Bay and Hiran. Methods: We analysed midline (CU5 n = 956; mothers n = 1066) and endline (CU5 n = 833; mothers n = 1023) data from a randomised controlled trial. We explored child (weight-for-height z-scores (WHZ)) and m…
Effective coverage for maternal health
Background: Efforts to improve maternal health have focused on measuring health and nutrition service coverage. Despite improvements in service coverage, maternal mortality rates remain high. This suggests that coverage indicators alone do not fully capture the quality of care and may overestimate the health benefits of a service. Effective coverage (EC) cascades have been proposed as an approach to capture service quality within population-based…
Analysing concordance between Muac, Muacz, and WHZ in diagnosing acute malnutrition among children under five in Somalia
Background: Acute malnutrition, also known as wasting, affected an estimated 45 million children under five (CU5) globally in 2023. Wasting is measured using a child's mid upper arm circumference (MUAC), weight-for-height z-score (WHZ), or nutritional oedema. In low-resource contexts, MUAC is often the only measurement used to regularly screen for malnutrition, but recent research suggests MUAC alone fails to diagnose 25-80% of WHZ-wasted childre…
Challenges in reducing maternal and neonatal mortality in Niger
INTRODUCTION: Recent modelled estimates suggest that Niger made progress in maternal mortality since 2000. However, neonatal mortality has not declined since 2012 and maternal mortality estimates were based on limited data. We researched the drivers of progress and challenges. METHODS: We reviewed two decades of health policies, analysed mortality trends from United Nations data and six national household surveys between 1998 and 2021 and assesse…
Climate shocks and nutrition
Niger is afflicted with high rates of poverty, high fertility rates, frequent environmental crises, and climate change. Recurrent droughts and floods have led to chronic food insecurity linked to poor maternal and neonatal nutrition outcomes in vulnerable regions. We analyzed maternal and neonatal nutrition trends and subnational variability between 2000 and 2021 with a focus on the implementation of policies and programs surrounding two acute cl…
Advancing nutrition measurement
The health sector plays an important role in the delivery of high-quality nutrition interventions to women and children in low- and middle-income countries (LMICs). However, there are no standardized approaches to defining and measuring nutrition service quality in these contexts. This study aims to systematically develop quality of care indices for direct health systems nutrition interventions using a five-step process: (1) identify recommended …
Trends and inequalities in the nutritional status of adolescent girls and adult women in sub-Saharan Africa since 2000
INTRODUCTION: Evidence on the rate at which the double burden of malnutrition unfolds is limited. We quantified trends and inequalities in the nutritional status of adolescent girls and adult women in sub-Saharan Africa. METHODS: We analysed 102 Demographic and Health Surveys between 1993 and 2017 from 35 countries. We assessed regional trends through cross-sectional series analyses and ran multilevel linear regression models to estimate the aver…
Program changes are effective and cost‐effective in increasing the amount of oil used in preparing corn soy blend porridge for treatment of moderate acute malnutrition in Malawi
Corn Soy Blend (CSB) porridge is commonly prepared with oil for treatment of moderate acute malnutrition (MAM). A recent review recommended that 30 g of oil be used with 100 g of CSB to increase energy density and micronutrient absorption. This study assessed the effectiveness and cost-effectiveness of program changes aimed at achieving that target oil:CSB ratio in prepared porridge. Caregivers of children in MAM supplementary feeding programs we…
Experiences and lessons learned for planning and supply of micronutrient powders interventions
Realistic planning for a nutrition intervention is a critical component of implementation, yet effective approaches have been poorly documented. Under the auspices of "The Micronutrient Powders Consultation: Lessons Learned for Operational Guidance," 3 working groups were formed to summarize experiences and lessons across countries regarding micronutrient powders (MNP) interventions for young children. This paper focuses on programmatic experienc…
