ABSTRACT

Objective: To analyze the situation and influencing factors of school meals leftover among primary and secondary school students in the area of the Nutrition Improvement Program for Rural Compulsory Education Students, improve the quality of school meals, develop healthy dietary behavior, and reduce food waste. Methods: In 2019, among the 50 monitoring counties that implemented the Compulsory Education Student Nutrition Improvement Program, two primary schools and two junior schools were randomly selected according to different food supply patterns.This study randomly selected one or two classes from grade 3 to grade 9. Basic information and school meals of 26 778 students were collected by using a student questionnaire. Multivariate logistic regression was used to analyze the influencing factors of leftovers rate. Results: 54.93% (14 709) of students wasted school meals, in which the highest rate was the staple food, with the main reason as "not in favor". 11.87% (1 743) of the students wasted school meals 6-7 days a week, with 54.20% (7 957) of students wasted but in less amount. The leftover rate of staple food was the highest (29.78%), followed by vegetables and meat. The main reason of leftovers was that they didn't like this kind of food (33.52%). The rate of school meal waste was higher for girls (OR=1.19,95%CI1.13-1.25), junior high school students (OR=1.17, 95%CI 1.11-1.25), resident students (OR=1.06, 95%CI 1.00-1.12), lower economic level (OR=1.06, 95%CI 1.00-1.12), parents working outside their houses (OR=1.22, 95%CI 1.13-1.30), health education classes (OR=1.70, 95%CI 1.40-2.06), company-based meals (OR=1.89, 95%CI 1.71-2.07) and school meals were not as good as home food(OR=1.89, 95%CI 1.78-2.00)(P<0.05). Conclusions: It is common for poor rural primary and middle school students in central and western China to waste school meals, and the reasons were affected by many factors. Reducing food waste requires the joint efforts of individuals, families, schools and society.
