The WHO guidelines were effective in the nutritional therapy of severely malnourished hospitalized children, resulting in good nutritional rehabilitation with low mortality rates.
If one considers the inadequate food intake observed in the dietary evaluation in this study, it is possible that multiple micronutrient deficiencies could be involved in statural deficits. This could explain why vitamin A supplementation does not seem to influence growth in children and adolescents with statural deficit, as indicated by the present study. Thus in populations such as the one studied here, the supplementation with vitamin A should be integrated into comprehensive nutritional interventions, so as to possibly promote greater positive impact on linear growth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
