摘　　要：目的分析抑郁症状在不健康生活方式与体质量指数(BMI)之间的中介效应,为预防青少年的常见病提供参考依据。方法于2023年在内蒙古地区12个盟市(103个旗县)范围内通过随机分层、以班为单位整群抽样法抽取88594名学生进行问卷调查,描述学生基本人口学特征,探究不健康生活方式、抑郁症状与BMI之间的相关关系,采用SPSS 26.0中的PROCESS宏程序建立中介效应模型。结果不健康生活方式的检出人数为85866,检出率为96.92%;BMI异常的检出人数为32078,检出率为36.21%;抑郁症状检出人数为19356,检出率为21.85%。结果显示抑郁症状在不健康生活方式与体质量指数之间的中介效应值为0.0770,95%CI:0.0513~0.1027,中介效应占总效应的11.35%,说明不健康生活方式可以通过抑郁症状介导BMI的增加。结论青少年可以通过改善不健康的生活方式预防体质量指数的异常,也可以通过改善抑郁症状的发生从而保持正常的体质指数。Objective To analyze the mediating effect of depressive symptoms between unhealthy lifestyle and body mass index(BMI),and to provide a reference basis for the prevention of common diseases among adolescents.Methods In 2023,88,594 students were selected by random stratified,class-based cluster sampling method from 12 municipalities in Inner Mongolia(103 counties)for questionnaire survey,to describe the basic demographic characteristics of the students,to explore the correlation between unhealthy lifestyle,depressive symptoms and BMI,and to establish the mediation effect model by using the PROCESS macro program in SPSS 26.0.Results The number of detections of unhealthy lifestyle was 85866,with a detection rate of 96.92 percent;the number of detections of abnormal BMI was 32078,with a detection rate of 36.21 per cent;and the number of detections of depressive symptoms was 19,356,with a detection rate of 21.85 per cent.The results showed that the mediating effect value of depressive symptoms on unhealthy lifestyle and body mass index was 0.0770,95%Cl:0.0513-0.1027,and the mediating effect accounted for 11.35%of the total effect,which indicated that unhealthy lifestyle could mediate the increase of BMI through depressive symptoms.Conclusion Adolescents can prevent abnormal body mass index by improving unhealthy lifestyles,and they can also improve the occurrence of depressive symptoms and thus maintain a normal body mass index.
