Evolution of the nutritional status and factors associated with undernutrition in children under five of age between 2014 and 2017 in 24 health districts of Burkina Faso

The prevalences of undernutrition in children under five years of age appeared to decrease over the last decade in Burkina Faso. However, the country is now facing new health and security challenges that could threaten this progress. Therefore, it is essential to monitor the evolution of the situation within this specific context. We aimed to assess trends in undernutrition among children under 5 years of age, as well as the factors associated with it, between 2014 and 2017 in Burkina Faso. A study based on secondary analysis of the data from 2013 and 2017 surveys, conducted in 24 districts across six health regions, was carried out. We worked with the household databases to select two sub-samples: 9,259 children from 2014 and 12,119 children from 2017. We assessed anthropometric indicators using World Health Organization standards, analyzed their proportions between 2017 and 2014, and according to the health regions and children’s age groups. We examined the association of stunting and underweight with children, mothers, and households’ characteristics in 2017 and for two selected health regions, using logistic regression. From 2014 to 2017, the proportion of severe stunting and severe underweight decreased respectively from 24.8% to 7.9% (p
