Status report on vitamin A deficiency and associated factors in the health area of Sanmatenga province (Burkina Faso)

Abstract Background Micronutrient deficiencies are a serious public health problem in sub-Saharan Africa, with particularly devastating consequences for children's health. In Burkina Faso, this burden, which is particularly marked by vitamin A deficiency, is exacerbated in certain areas where security and humanitarian problems are reducing access to health and nutrition services. One of the solutions most promoted at national level to deal with these micronutrient deficiencies is the use of lipid-based nutrient supplements (LNS). In order to understand the extent of this burden of malnutrition and to enable the strategy to be evaluated, it is necessary to carry out an epidemiological assessment of the nutritional status of children before implementing supplementation. Methods The nutritional status of the children was assessed using anthropometric measurements and serum retinol concentration. Interviews were conducted with the children's mothers to determine their feeding practices. Binary logistic regression was used to determine the variables associated with vitamin A deficiency with statistical significance at p p Results The results showed that 86. 6% of the children were vitamin A deficient. In addition, only 11. 8% had a minimum dietary diversity. It emerged that 1. 4% of the children had eaten roots, tubers and vegetables rich in vitamin A the day before the survey, and only 3. 5% had eaten fruit rich in vitamin A. The study also showed that there was a statistically significant association (p Conclusions The results show the actual level of vitamin A deficiency in the study area and provide a factual basis for adopting strategies to address the problem of vitamin A deficiency. Trial registration the Ethics Committee for Health Research in Burkina Faso has given its authorisation for this study under number 2022₆0_/MSHP/MESRSI/CERS of 03/02/2022.
