Demographic information, dietary and exercise behaviors were collected using questionnaire surveys, and the prevalence of malnutrition were analyzed. Factors affecting malnutrition was evaluated using a multinomial logistic regression model.
Results:A total of 7 213 students were surveyed, including 3 881 boys (53.81%) and 3 332 girls (46.19%), and had a median age of 13.50 (interquartile range, 4.00) years. There were 2 667 primary school students (36.97%), 2 662 middle school students (36.91%) and 1 884 high school students (26.12%). There were 1 938 students suffered from malnutrition, with a detection rate of 26.87%. The detection rates for undernutrition, overweight and obesity were 11.66%, 9.75% and 5.46%, respectively. Multinomial logistic regression analysis showed that gender (boy, OR=2.227, 95%CI: 1.905-2.603), studying phase (primary school, OR=1.528, 95%CI: 1.239-1.884), ≥60 min/d of moderate/high-intensity exercise (0-1 d/week, OR=1.422, 95%CI: 1.153-1.753; 2-4 d/week, OR=1.280, 95%CI: 1.047-1.564) and frequency of having physical education (1-2 classes/week, OR=1.732, 95%CI: 1.084-2.767; 3-4 classes/week, OR=1.662, 95%CI: 1.026-2.693) were the influencing factors for undernutrition; gender (boy, OR=1.956, 95%CI: 1.656-2.311), frequency of sugary beverage intake (0 time/d, OR=0.721, 95%CI: 0.528-0.984) and frequency of having physical education (0 class/week, OR=2.087, 95%CI: 1.151-3.784; 1-2 classes/week, OR=1.644, 95%CI: 1.044-2.590; 3-4 classes/week, OR=1.685, 95%CI: 1.051-2.703) were the influencing factors for overweight; gender (boy, OR=2.459, 95%CI: 1.964-3.078) was the influencing factor for obesity among students.
