Abstract: Objective To estimate the prevalence of dietary supplement use in Chinese children and assess the average daily intake of nutrient from dietary supplement. Methods By multiple stage stratified cluster sampling,1 823 children aged 3~12 years old were chosen and provided with dietary supplement questionnaire finished by their proxies. Result Preschoolers exhibited a higher prevalence of supplemental vitamin and mineral use during the past half year than school-age children.The most used supplements in participants were Calcium(27.46%),Vitamin D(16.61%),Zinc(13.73%),Vitamin B2(12.35%),Vitamin C(12.18%),Vitamin A(11.35%),Vitamin B6(10.47%),Folic acid(8.68%),Niacin(7.03%),Pantothenic acid(6.7%),Vitamin E(6.17%) ,and Iron (4.87%).Daily intake of each kind of nutrients ranged widely,some of which with a maximum amount over upper level of intake (UL).Most of the nutrients' intake from supplement were lower than recommended,while the mean value and the median of Vitamin A intake of children aged 3~6 years old were both over the recommend level. Conclusions There is a risk of excess intake of vitamin A supplements.Supplements intake recommendations should be established in order to assess children's nutritional status and potential health risks appropriately.
