To evaluate the association between calcium intake and serum vitamin D levels and childhood obesity by an integrative review. The research was conducted in the databases PubMed/medLine, Science Direct and SciELO with 2001 to 2014 publications. We used the combined terms in English: "children" and "calcium" or "children" and "vitamin D" associated with the descriptors: "obesity", "adiposity" or "body fat" for all bases. Cross-sectional and cohort studies as well as clinical trial were included. Review articles or those that that have not addressed the association of interest were excluded. Eight articles were part of this review, five of which were related to calcium and three to vitamin D. Most studies had a longitudinal design. The analyzed studies found an association between calcium intake and obesity, especially when age and sex were considered. Inverse relationship between serum vitamin D and measures of adiposity in children has been observed and this association was influenced by the sex of the patient and by the seasons of the year. The studies reviewed showed an association between calcium and vitamin D with childhood obesity. Considering the possible protective effect of these micronutrients in relation to childhood obesity, preventive public health actions should be designed, with emphasis on nutrition education.
