RELATIONSHIP BETWEEN MACRONUTRIENTS INTAKE AND OVERWEIGHT/OBESITY AMONG CHINESE CHILDREN AND ADOLESCENTS AGED 6-17 YEARS IN 2018
Objective To analyze the relationship between percentage of energy from macronutrients and overweight/obesity and body mass index(BMI)among children and adolescents aged 6-17 years in 15 provinces of China in 2018.Methods The data were collected from the China Health and Nutrition Survey(CHNS)and China Nutrition Transition Cohort Study.A sample of 1464 children and adolescents aged 6-17 years with complete information in 2018 were included.Consecutive 3 d 24 h recalls and weighting method were used to collect food intake data.Generalized linear model and logistic regression model were applied to analyze the relationship between macronutrients intake and BMI and overweight/obesity,respectively.Results The rate of overweight/obesity among children and adolescents was 22.5%in 2018.After adjusting for confounding factors,compared to the group with less than 10%energy from protein,the group with 12%to 15%(β=0.71,95%CI:0.19,1.22)and greater than or equal to 15%(β=0.78,95%CI:0.21,1.34)were positively correlated with BMI,and the risk of overweight/obesity increased by 47%and 58%in the group with 12%to 15%(OR=1.47,95%CI:1.01,2.14)and greater than or equal to 15%(OR=1.58,95%CI:1.06,2.37),respectively.The group with greater than or equal to 55%energy from carbohydrate(OR=1.47,95%CI:1.02,2.11)had a 47%increased risk of overweight/obesity compared to the group with less than 40%energy from carbohydrate.Conclusion Protein and carbohydrate intake were positively associated with overweight/obesity and BMI in children and adolescents.
