中学生抑郁症状与不良饮食行为的关联

Correlation of depressive symptoms and unhealthy eating behaviors in middle school students

目的:了解重庆市中学生抑郁症状流行现况,探讨与不良饮食行为的关联。方法:采用多阶段分层整群抽样方法,抽取重庆市4个区县8所完全中学,共9167名中学生,使用流调中心抑郁量表(CES-D)评估抑郁症状(CES-D评分≥20分判定为具备抑郁症状),使用饮食行为调查问卷评估不良饮食行为。结果:重庆市中学生抑郁症状的检出率为31.81%(2916/9167)。Logistics回归分析显示,控制了其他因素后,不良饮食行为最高的中学生抑郁症状的检出率最高(OR=8.55,95%CI:2.60~28.09),限制性立方样条模型显示,抑郁症状检出率与不良饮食行为数量之间存在正相关线性关系(非线性检验P>0.05)。结论:重庆市中学生抑郁症状处于较高水平,并与较高水平的不良饮食行为相关。

Objective:To investigate the prevalence of depressive symptoms among middle school students in Chongqing,and to explore its association with unhealthy eating behaviors.Methods:Using stratified multistage clus-ter sampling,9167 middle school students were selected from 8 secondary schools in 4 districts and counties of Chongqing.The Depression Scale of the Center for Epidemiological Studies(CES-D)was used to assess depressive symptoms(CES_D score of≥20 points was judged to have depressive symptoms),and the dietary behavior ques-tionnaire was used to assessment of unhealthy eating behaviors.Results:The prevalence of depressive symptoms a-mong the middle school students in Chongqing was 31.81%(2916/9167).Participants with the highest unhealthy eating behaviors had a higher prevalence of depressive symptoms(OR=8.55,95%CI:2.60-28.09),and the re-strictive cubic spline model showed a positive linear relationship between the prevalence of depressive symptoms and the number of unhealthy eating behaviors(nonlinear test P>0.05).Conclusions:The prevalence of depressive symptoms among secondary school students in Chongqing is at a high level,and it is related to a high level of un-healthy eating behaviors.
