【Abstract】 In recent years, with the development of medical and health care, vitamin D deficiency（VDD） has received more and more attention in the growth and development of children, and the incidence is high. Vitamin D is mainly derived from vitamin D₃ transformed by skin exposure to sunlight. VDD is mainly manifested as rickets and tetany. At present, the diagnostic criteria for VDD are still controversial, and the treatment plan is generally divided into daily and weekly treatment plans. This article reviews the research progress on VDD in children from epidemiology, metabolic mechanism and etiology, clinical manifestations, diagnosis, treatment and prevention, in order to provide some clinical reference for VDD in children.更多还原
