Abstract:
Objective:To explore the effect of learning stress on weight and the mediating effect abnormal eating behavior in junior high school students.Methods:By multi-stage stratified cluster sampling,2 686 junior high school students were selected and investigated the learning stress and abnormal eating behavior with the middle school students' learning stress questionnaire and the Chinese version of the Dutch eating behavior questionnaire(C-DEBQ).The height and weight of the students were measured and the body mass index(BMI)was calculat-ed.Bootstrap method was used to analyze the mediating effect by using Process 4.1 software.Results:The preva-lence of overweight and obesity among 2 686 junior high school students was 19.8％.The score of middle school students'learning stress questionnaire was(57.6±11.3),the score of restricted eating was(20.0±7.3),the score of emotional eating was(21.3±9.5),and the score of exogenous eating was(25.8±7.7).There was a positive correlation between learning stress,restricted eating,emotional eating,overweight and obesity(r=0.08-0.24,Ps＜0.001).In the relationship between learning stress and overweight and obesity,the total indirect effect coefficient of restrictive eating behavior and emotional eating behavior was 0.013,indicating a partial mediating effect(95％CI:0.010-0.015,0.001-0.002).Conclusion:Learning stress could directly or indirectly affect the weight of junior high school students through abnormal eating behavior,increasing the risk of overweight and obesity.
