Potential Impact of Large‐Scale Food Fortification in Ethiopia: Coverage and Knowledge of Fortifiable Foods
Large-scale food fortification (LSFF) is an effective public health measure because it may reach a large number of populations at risk using current food delivery systems. The objective of the study was to assess coverage and consumption of fortifiable foods at the household level and to assess the potential impact of LSFF on child outcomes (stunting and survival) in Ethiopia. Cross-sectional survey data on sociodemographic characteristics, dieta…
Comparing two simplified questionnaire‐based methods with 24‐h recalls for estimating fortifiable wheat flour and oil consumption in Mandaluyong City, Philippines
Information on fortifiable food consumption is essential to design, monitor and evaluate fortification programmes, yet detailed methods like 24-h recalls (24HRs) that provide such data are rarely conducted. Simplified questionnaire-based methods exist but their validity compared with 24HRs has not been shown. We compared two simplified methods (i.e., a household food acquisition and purchase questionnaire [FAPQ] and a 7-day semiquantitative food …
Micronutrient deficiencies among preschool-aged children and women of reproductive age worldwide: A pooled analysis of individual-level data from population-representative surveys
BACKGROUND: Micronutrient deficiencies compromise immune systems, hinder child growth and development, and affect human potential worldwide. Yet, to our knowledge, the only existing estimate of the global prevalence of micronutrient deficiencies is from over 30 years ago and is based only on the prevalence of anaemia. We aimed to estimate the global and regional prevalence of deficiency in at least one of three micronutrients among preschool-aged…
Preventive small-quantity lipid-based nutrient supplements reduce severe wasting and severe stunting among young children: An individual participant data meta-analysis of randomized controlled trials
Including SQ-LNSs in preventive interventions to promote healthy child growth and development is likely to reduce rates of severe wasting and stunting. This meta-analysis was registered at www.crd.york.ac.uk/PROSPERO as CRD42019146592.
Making programmes worth their salt: Assessing the context, fidelity and outcomes of implementation of the double fortified salt programme in Uttar Pradesh, India
Double fortified salt (DFS) has proven efficacy in addressing iron deficiency and anaemia, thus improving maternal and child nutrition outcomes. However, DFS delivery in large-scale settings is less understood, with limited documentation of its fidelity of implementation (FOI). We assessed the FOI of the DFS intervention in Uttar Pradesh, India, to improve the design and implementation of such programmes that aim to reduce the anaemia burden, esp…
Food Insecurity and Water Insecurity in Rural Zimbabwe: Development of Multidimensional Household Measures
Background : With millions of people experiencing malnutrition and inadequate water access, FI and WI remain topics of vital importance to global health. Existing unidimensional FI and WI metrics do not all capture similar multidimensional aspects, thus restricting our ability to assess and address food- and water-related issues. Methods : Using the Sanitation, Hygiene and Infant Nutrition Efficacy (SHINE) trial data, our study conceptualizes hou…
Role of home visits by volunteer community health workers: To improve the coverage of micronutrient powders in rural Bangladesh
Objective: We assessed the role of home visits by Shasthya Shebika (SS) – female volunteer community health workers (CHWs) – in improving the distribution of micronutrient powder (MNP), and explored the independent effects of caregiver–provider interaction on coverage variables. Design: We used data from three cross-sectional surveys undertaken at baseline ( n 1927), midline ( n 1924) and endline ( n 1540) as part of an evaluation of a home forti…
Cost-effectiveness of a market-based home fortification of food with micronutrient powder programme in Bangladesh
Objective: We estimated the cost-effectiveness of home fortification with micronutrient powder delivered in a sales-based programme in reducing the prevalence of Fe deficiency anaemia among children 6–59 months in Bangladesh. Design: Cross-sectional interviews with local and central-level programme staff and document reviews were conducted. Using an activity-based costing approach, we estimated start-up and implementation costs of the programme. …
Factors associated with home visits by volunteer community health workers to implement a home-fortification intervention in Bangladesh: A multilevel analysis
Objective: BRAC, an international development organization based in Bangladesh, engages community health workers called Shasthya Shebikas (SS) to implement home fortification of foods with micronutrient powders (MNP). We identified factors associated with home visits by SS, at different levels of the BRAC programme-delivery hierarchy, to implement home-fortification interventions. Design: We conducted a cross-sectional survey, semi-structured int…
Firm’s compliance behaviour towards food fortification regulations: Evidence from oil and salt producers in Bangladesh
Impact of national food fortification programs is contingent on the extent to which there is compliance with national standards. However, this compliance is often sub-optimal and is not consistently measured. One of the challenges to more regular measurement is an over-reliance on quantitative assessments of micronutrient levels for compliance, which are costly. In resource constrained environments, this contributes to weaknesses in regulatory mo…
Understanding drivers of private-sector compliance to large-scale food fortification: A case study on edible oil value chains in Bangladesh
Micronutrient deficiency is a pertinent global challenge that affects billions of people and has deleterious health effects. Large-scale food fortification (LSFF) is a cost- effective way to tackle micronutrient deficiency and improve health outcomes, particularly in low- and middle-income countries (LMICs). However, the success of LSFF in LMICs is often hampered by limited compliance with fortification mandates by the private sector, who supply …

Effects of improved complementary feeding and improved water, sanitation and hygiene on early child development among HIV-exposed children: Substudy of a cluster randomised trial in rural Zimbabwe
Introduction: HIV-exposed uninfected children may be at risk of poor neurodevelopment. We aimed to test the impact of improved infant and young child feeding (IYCF) and improved water, sanitation and hygiene (WASH) on early child development (ECD) outcomes. Methods: Sanitation Hygiene Infant Nutrition Efficacy was a cluster randomised 2×2 factorial trial in rural Zimbabwe ClinicalTrials.gov NCT01824940). Pregnant women were eligible if they lived…
Maternal caregiving capabilities are associated with child linear growth in rural Zimbabwe
Between birth and 2 years, children's well-being depends on the quality of care they receive from caregivers, primarily their mothers. We developed a quantitative survey instrument to assess seven psychosocial characteristics of women that determine their caregiving ability ('maternal capabilities': physical health, mental health, decision-making autonomy, social support, mothering self-efficacy, workload and time stress, and gender norm attitude…
Independent and combined effects of improved water, sanitation, and hygiene, and improved complementary feeding, on child stunting and anaemia in rural Zimbabwe: A cluster-randomised trial
BACKGROUND: Child stunting reduces survival and impairs neurodevelopment. We tested the independent and combined effects of improved water, sanitation, and hygiene (WASH), and improved infant and young child feeding (IYCF) on stunting and anaemia in in Zimbabwe. METHODS: We did a cluster-randomised, community-based, 2 × 2 factorial trial in two rural districts in Zimbabwe. Clusters were defined as the catchment area of between one and four villag…
Bottlenecks and predictors of coverage and adherence outcomes for a micronutrient powder program in Ethiopia
A theory-driven evaluation was conducted to assess performance of a trial to deliver micronutrient powder (MNP) through the Ethiopian Ministry of Health. We adapted an approach to coverage assessment, originally developed to identify bottlenecks in health service delivery, to examine sequential program outcomes and their correlates using cross-sectional survey data of caregivers of children 6-23 months (N = 1915). Separate multivariable Poisson r…
Water, sanitation, and hygiene (Wash), environmental enteropathy, nutrition, and early child development: Making the links
There is scarce research and programmatic evidence on the effect of poor water, sanitation, and hygiene (WASH) conditions of the physical environment on early child cognitive, sensorimotor, and socioemotional development. Furthermore, many common WASH interventions are not specifically designed to protect babies in the first 3 years of life, when gut health and linear growth are established. We review evidence linking WASH, anemia, and child grow…
Addressing social barriers and closing the gender knowledge gap: Exposure to road shows is associated with more knowledge and more positive beliefs, attitudes and social norms regarding exclusive brea…
Exclusive breastfeeding (EBF) is rarely practiced despite its significant child survival benefits. A key constraint to increasing EBF rates in Zimbabwe and most of the developing world is that key decision makers (fathers/partners and other family members) are often poorly informed about EBF and do not attend antenatal clinics where health information is routinely provided. Informed by formative research, a district-wide campaign was conducted in…
Complementary feeding messages that target cultural barriers enhance both the use of lipid‐based nutrient supplements and underlying feeding practices to improve infant diets in rural Zimbabwe
Supplementation with lipid-based nutrient supplements (LiNS) is promoted as an approach to prevent child undernutrition and growth faltering. Previous LiNS studies have not tested the effects of improving the underlying diet prior to providing LiNS. Formative research was conducted in rural Zimbabwe to develop feeding messages to improve complementary feeding with and without LiNS. Two rounds of Trials of Improved Practices were conducted with mo…
