Objective To investigate the situation of snacking intake and nutrients supplementation in Chinese children and adolescents aged 3-17 years,in order to provide scientific guidance for snacking in children and adolescents. Methods Data were extracted from the China Health and Nutrition Study(CHNS) in 2011. The amount of nutrients dietary intake in different snacking groups was described,and was compared with Chinese dietary reference intakes. Results A total of 2 012 valid subjects were included in the study,of whom 68.84% had snacking,and the medium of energy supply ratio was 9%. The participants were divided into snacking 1(S1) group and snacking 2(S2) group according to the energy supply ratio. The energy supply ratio in S2 group was higher,while it was contrast in S1 group. The highest percentage of snacking was fruits(79.28%),and 29.17% of the snacking were dairy in snacking group. The amount of nutrients supplementation was higher in S2 group than that in group without snacking,and the difference was significant in different age groups(P＜0.05) . In this study,the proportion of nutrients meeting estimated average requirement in S2 group was higher than no snacking group. Also,the proportion of vitamin A,Fe and Zn intake more than tolerable upper intake levels in snaking group was much higher. Conclusions Snacking behavior would increase the amount of nutrients intake,and decrease the proportion of insufficient of nutrients intake to a large extent. As a result,scientific and reasonable snacking behavior is suggested to be advocated in children and adolescents.
