Abstract

Objective To investigate the distribution characteristics and related factors of weight loss behavior among middle school students in Shanghai, so as to provide a reference for guiding scientific weight loss among middle school students. Methods From May to June 2021, a stratified cluster random sampling method was used to select 16 758 junior and high school students in 16 districts of Shanghai. Youth Risk Behavior Surveillance System was administered to assess the basic condition and weight loss behaviors of the students. An unordered multinomial Logistic regression model was employed to analyze the factors associated with weight loss behaviors. Results A total of 5 881 (35.09%) reported engaging in exercise for weight loss, 6 344 (37.86%) reported dieting for weight loss, and 461 (2.75%) engaged in unhealthy weight loss behaviors. The unordered multinomial Logistic regression analysis indicated that compared with the no-weight-loss behavior group, students from urban areas(OR=1.35, 95%CI=1.10-1.66), those with Internet addiction (OR=1.71, 95%CI=1.23-2.38), those with victims of bullying (OR=2.09, 95%CI=1.68-2.61), those experiencing insomnia (OR=2.33, 95%CI= 1.74-3.11), those feelings of sadness or despair (OR=3.10, 95%CI=2.42-3.97), and those who perceived their body weight as slightly heavy (OR=2.77, 95%CI= 2.17-3.55) or very heavy (OR=3.41, 95%CI=2.44-4.75) were more likely to engage in unhealthy weight loss behaviors (P<0.05). Conclusions There are significant differences in weight loss behaviors among middle school students with varying characteristics in Shanghai. Negative emotions such as insomnia and feelings of sadness or despair, Internet addiction, cognitive bias in weight and experiences of bullying are identified as related factors for unhealthy weight loss behaviors. Targeted intervention measures should be implemented to guide students towards scientific approaches to weight management.
