The empirical context of this research is in an environment where malnutrition is a real public health concern. The objective of this study was to identify the determinants of the nutritional state of children under the age of five years in Mauritania. Using data obtained from multiple indicators cluster surveys (MICS) in Mauritania in 2007 and 2015, we undertook fixed-effects clusters techniques to control for unobserved heterogeneity. The empirical results demonstrate that the age and sex of a child,
level of education of the mother, the standards of living of the household, the area of residence, the availability and use of health care services and access to drinking water are all important factors for the good health of children in Mauritania. These findings suggests improvements in nutritional health, for example, by education of girls until completion of secondary school; an improvement in the conditions of households that are headed by women and an expansion in the coverage rate of
multi-purpose health centres.
