Associations between 25-hydroxyvitamin D, obesity and metabolic syndrome in US children.

What is it about?

Low serum 25-hydroxyvitamin D(25(OH)D) concentration has been associated with obesity and metabolic syndrome (MetS), but few studies have addressed these associations in the USA where the prevalence of vitamin D deficiency, obesity and related metabolic disorders in children is high. The study described by Fu et al concludes that low serum 25(OH)D concentration is associated with increased risk for obesity and MetS among US children and adolescents. These authors add new knowledge to the literature by highlighting gender differences in the association between serum 25(OH)D concentration, obesity and metabolic parameters. Further studies are needed to better elucidate the causality and potential mechanisms underlying gender differences in these relationships.
