摘要:
目的 分析宠物饲养和户外活动时长与中学生抑郁症状的关联, 为有针对性地制定预防中学生抑郁症状发生的相关策略提供参考依据。 方法 采用分层整群随机抽样方法, 于2024年抽取内蒙古自治区103个区县83 601名初、高中学生, 通过问卷调查收集研究对象的人口学资料、家庭是否饲养宠物、户外活动时长及抑郁症状情况。不同组别中学生抑郁症状的报告率比较采用χ2检验, 宠物饲养和户外活动时长与中学生抑郁症状的关联采用Logistic回归模型评估, 并在不同性别和地区人群中进行分层分析, 控制潜在混杂因素后评估关联的稳定性。 结果 内蒙古中学生抑郁症状的检出率为17.2%。不同性别、年级、民族、监测点、父母学历、是否来月经/遗精、是否住校、是否吸烟/饮酒、过去7 d内是否每天吃早餐、是否校园欺凌、是否在嘈杂环境中连续30 min使用耳机、是否经常上网的中学生抑郁症状检出率差异均有统计学意义(χ2=8.07~2 672.57, P值均 < 0.01)。二元Logistic回归分析显示, 宠物饲养(OR=0.78, 95%CI=0.75~0.81)和户外活动时长≥2 h/d(OR=0.81, 95%CI=0.78~0.84)的中学生抑郁症状发生风险均较低; 相较于"户外活动时长 < 2 h/d+不饲养宠物"组, "户外活动时长≥2 h/d+宠物饲养"组的中学生(OR=0.83, 95%CI=0.78~0.87)抑郁症状的发生风险更低(P值均 < 0.05)。 结论 饲养宠物和增加户外活动时长有助于缓解中学生抑郁症状。 Abstract:Objective To examine the associations of pet ownership and daily outdoor activity duration with depressive symptoms in middle school students, so as to provide evidence for targeted prevention strategies of depressive symptoms in middle school students. Methods Using a stratified cluster random sampling method, 83 601 middle and high school students from 103 districts and counties in Inner Mongolia Autonomous Region were selected in 2024. A questionnaire survey was conducted to collect demographic data, household pet ownership, outdoor activity duration, and depressive symptoms of the research subjects. The comparison of reporting rates of depressive symptoms among different groups of middle school students was conducted using a χ2 test. The association between pet ownership and outdoor activity duration and depressive symptoms among middle school students was evaluated using a Logistic regression model, and stratified analysis was conducted among different genders and regions to control for potential confounding factors and evaluate the stability of the association. Results The prevalence of depressive symptoms among middle-school students in Inner Mongolia was 17.2%. Significant differences in depressive symptom reporting rates were observed across sex, grade, ethnicity, surveillance site, parental education, menarche/spermarche status, boarding status, smoking and alcohol use, daily breakfast consumption, school bullying, continuous 30-minute headphone use in a noisy environment, and often use the Internet (χ2=8.07-2 672.57, all P < 0.01). Both pet ownership (OR=0.78, 95%CI=0.75-0.81) and ≥2 h/d of outdoor activity(OR=0.81, 95%CI=0.78-0.84) were inversely associated with depressive symptoms; compared to the without owning pets and < 2 h of outdoor activity daily group, students who both owned pets and engaged in ≥2 h of outdoor activity daily had an even lower risk (OR=0.83, 95%CI=0.78-0.87)(all P < 0.05). Conclusion Pet ownership and increased daily outdoor activity duration may help mitigate depressive symptoms among middle school students. -
