Progress of research on the relationship between vitamin D deficiency and obesity among children
Vitamin D(Vit D)deficiency is prevalent worldwide,and the prevalence of childhood obesity is increasing globally.Many studies have supported that Vit D deficiency may be an important cause of childhood obesity,and the level of serum Vit D a-mong obese children decreases,simultaneously.Both Vit D deficiency and obesity among children interact through direct factors,molecular mechanisms and environmental factors,but the mechanism of interaction has not been fully elucidated.In the future,higher level research in evidence-based medicine could be conducted to explore the association between childhood obesity and Vit D deficiency and the possible mechanisms of their interaction,in order to provide scientific evidence for the prevention and control of Vit D deficiency and obesity among children.
