Depuis les crises alimentaires des années 1970 et 1980, les pays sahéliens ont exploré diverses stratégies pour gérer le risque d’insécurité alimentaire. Cependant, leurs approches intègrent souvent mal les déterminants complexes de la vulnérabilité alimentaire et de la malnutrition. C’est pourquoi, l’IRD et l’Université de Ouagadougou ont mis en p...
Accurate determination of pre-pregnancy weight is essential for optimal pregnancy monitoring and antenatal care. Determining pre-pregnancy weight in limited-resources settings is challenging for both clinical practice and public health research. From a 2014–2017 pre-pregnancy cohort in Benin, we evaluated the agreement between the measured pre-preg...
Two plant production-based strategies – biofortification and dietary diversification – have been advocated to overcome micronutrient deficiencies, which are major contributors to morbidity and mortality worldwide. The respective benefits and effectiveness of these two strategies are the subject of controversy. Expanding the scope of this debate bey...
Background
The Minimum Dietary Diversity for Women of Reproductive Age (MDD-W) indicator was validated as a proxy of micronutrient adequacy among nonpregnant women in low- and middle-income countries (LMICs). At that time, indeed, there was insufficient data to validate the indicator among pregnant women, who face higher micronutrient requirements....
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...
Diets are changing everywhere, and the burden of disease associated with unhealthy diets is a worldwide concern. Measurement and monitoring of diets across countries and population groups is critical. However, there are no harmonized metrics for tracking how the healthfulness of diets around the world is evolving.

This study measured the impact of a food voucher distribution of the World Food Program targeting vulnerable households in two cities of Senegal. We use...
Micronutrient malnutrition is a challenge for women of reproductive age, who are particularly vulnerable due to greater micronutrient needs. The minimum dietary diversity for women (MDD‐W) indicator is a micronutrient adequacy's proxy for those women, but little is known about its relation to other dimensions. We assessed MDD‐W and its association...
Dietary diversity before and during pregnancy is crucial to ensure optimal foetal health and development. We carried out a cohort study of women of reproductive age living in the Sô‐Ava and Abomey‐Calavi districts (Southern Benin) to investigate women's changes in dietary diversity and identify their determinants both before and during pregnancy. N...

Background
The popularity of nutrition-sensitive interventions calls for high-quality monitoring and evaluation tools. In this context, the Minimum Dietary Diversity for Women of Reproductive Age (MDD-W), validated as a proxy of micronutrient adequacy, does fill a gap. However, because it is a newly endorsed indicator, information on its linkages w...
Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of heigh...
Tunisia is a typical country of the Mediterranean region where high prevalence of overweight, obesity and non-communicable diseases co-exist with some micronutrient deficiencies, and diet-related environmental issues must be addressed. Individual food choices may influence both health and environment. The aim of this study was to identify diets tha...
Background:
In sub-Saharan Africa, malaria in the first half of pregnancy is harmful for both the mother and her fœtus. However, malaria in the 1st trimester of pregnancy, when women are usually not protected against malaria, has been little investigated. For the first time, we assessed the effects of malaria in the 1st trimester on maternal and bi...
Background:
According to the DOHaD paradigm, the foetal period is one of the most vulnerable periods that may have profound effects on health later in life. Few studies have assessed the effect of small-birth-weight-for-gestational age (SGA), a proxy for foetal growth impairment, on the risk of malaria during infancy in Africa.
