Malnutrition still affects the population in low-income countries. In Burkina Faso, the estimated prevalence of anemia is high among preschool-aged children and women of childbearing age (83.4% and 53%, respectively in 2014). As part of the MERIEM fortification project, a survey was carried out in 2022 in Ouagadougou to describe dietary practices a...

Quantitative assessment of foods consumed when using 24-hour dietary recall requires accurate tools to estimate portion sizes. Therefore, we developed a food portion photography atlas with age-appropriate portion sizes for 11 foods frequently consumed by young children (sizes for 6-11-month- and for 12-23-month-old children) and women of childbeari...

Micronutrients powder (MNP) can prevent anemia among children 6‐23 months old. However, evidence of an effect on growth is limited and concerns about the safety of iron‐containing MNP interventions limits their applicability. In a cluster‐randomized controlled intervention, we evaluated the effectiveness of a nutritional package including counselin...

L’objectif de cette étude est d’identifier les facteurs prédictifs du décès des enfants en milieu rural dans un contexte de supplémentation alimentaire au Burkina Faso. Il s’agit d’une étude cas témoins appariée (1 :2), nichée dans une cohorte. une régression de Cox a été utilisée pour rechercher les facteurs prédictifs du décès. Un seuil de signif...

Objective To identify individual‐level effect modifiers of the effect of multiple micronutrient supplementation (MMS) containing iron and folic acid (IFA) during pregnancy, compared to IFA alone, on the risk of stillbirth, infant mortality, and birth outcomes. Methods We performed an individual patient data meta‐analysis. Study‐specific estimates...

Objective The Food Aid Quality Review (FAQR), a study implemented by Tufts University, recommended improvements in the formulations and programming of existing Title II supplementary foods. To test these recommendations, we are examining the effectiveness and cost‐effectiveness of four different supplementary foods in the prevention of stunting and...

Background: Micronutrient deficiencies are common among women in low-income and middle-income countries. Data from randomised trials suggest that maternal multiple micronutrient supplementation decreases the risk of low birthweight and potentially improves other infant health outcomes. However, heterogeneity across studies suggests influence from e...

The period from conception to 24 months of age is a crucial window for nutrition interventions. Personalized maternal counseling may improve childbirth outcomes, growth, and health. We assessed the effectiveness of facility-based personalized maternal nutrition counseling (from pregnancy to 18 months after birth) in improving child growth and healt...

It is important to understand and account for seasonal variation in food and nutrient intakes when planning interventions to combat micronutrient defi-ciencies in resource-poor settings. The objective of the present study was to quantify food and nutrient intakes and assess the adequacy of micronutrient intakes among young children and their mother...

Management of moderate acute malnutrition (MAM) is, currently, focused on food supplementation approaches. However, the sustainability of these strategies remains weak in low- and middle-income countries. In food-secure settings, an educational/behavioral intervention could be an alternative for improving MAM management. This study compared the eff...

Prenatal lipid-based nutrient supplements (LNS) have been shown to improve birth anthropometry. However, little is known about the effects of such supplements on infant health. We hypothesized that prenatal LNS compared with multiple micronutrient supplement for pregnant and lactating women would improve survival, growth, and morbidity during infan...

The objective of the study was to assess the impact of spirulina supplementation on selected anthropometric, biochemical, and hematological parameters of HIV-infected adults in Ouagadougou. This quasi-experimental two-arm pilot study was conducted with adults infected with HIV-1 in Ouagadougou, Burkina Faso. A group of 50 participants received a 10...

In developing countries, prenatal lipid-based nutrient supplements (LNSs) were shown to increase birth size; however, the mechanism of this effect remains unknown. Cord blood hormone concentrations are strongly associated with birth size. Therefore, we hypothesize that LNSs increase birth size through a change in the endocrine regulation of fetal d...

Prenatal multiple micronutrients (UNIMMAP) improve fetal growth only moderately compared to iron and folic acid alone (IFA). Whether this is due to insufficient amounts of UNIMMAP or to IFA being in reality an active control is unknown. We assessed the association between cumulative micronutrient intake (CMI) and fetal growth by secondary analysis...

Although prenatal multiple micronutrients can improve fetal growth, their benefit on postnatal health remains uncertain. We assessed the effect of the UNICEF/WHO/United Nations University multiple micronutrient supplement for pregnant and lactating women (UNIMMAP) compared with the usual iron and folic acid supplement (IFA) on survival, growth, and...

The most appropriate dose of iron to prevent maternal anemia is still unclear. We assessed the dose-response relation between maternal hemoglobin and 2 prenatal iron supplements. An intention-to-treat, double-blind, randomized controlled trial compared 30 mg Fe + folic acid and 13 other micronutrients (UNIMMAP; UNICEF/WHO/UNU multiple micronutrient...

Fetal growth improves in pregnant women who take daily maternal multiple micronutrients [United Nations International Multiple Micronutrient Preparation (UNIMMAP)] rather than iron and folic acid (IFA) alone. Our objective was to test whether such an effect was mediated by changes in concentrations of cord hormones. In a double-blind, controlled tr...

Prenatal multiple micronutrient (MMN) or balanced energy and protein supplementation has a limited effect on birth size of the offspring. The objective was to determine whether a prenatal MMN-fortified food supplement (FFS) improves anthropometric measures at birth compared with supplementation with an MMN pill alone. We conducted a nonblinded, ind...
