摘要:
目的 了解南京市中学生抑郁症状现况,探讨视屏时间、睡眠时间与抑郁症状的关系,为预防青少年抑郁提供科学依据。 方法 分层整群随机选取南京市城区5所中学、郊县3所中学共2 010名学生,通过问卷调查中学生视屏时间和睡眠时间,应用流调中心用抑郁量表(CES-D)评价抑郁症状。 结果 27.71%(557名)的中学生存在抑郁症状(CES-D≥16分)。Logistic回归分析显示,视屏时间>2 h/d(OR=1.90,95%CI=1.53~2.37)、睡眠时间 < 7 h/d(OR=2.54,95%CI=1.88~3.42)与抑郁症状发生风险增加有关。按视屏时间分层分析发现,睡眠时间 < 7 h/d与抑郁症状的关联在视屏时间>2 h/d组(OR=2.46,95%CI=1.64~3.71)高于视屏时间≤2 h/d组(OR=2.35,95%CI=1.51~3.65)。 结论 南京市中学生抑郁症状检出率较高,视屏时间长、睡眠时间少与抑郁症状风险增加相关。应重点关注视屏行为和睡眠不足联合暴露下青少年的心理健康。 Abstract:Objective To explore the prevalence of depressive symptoms among middle school students in Nanjing and the relationship between screen time, sleep duration and depressive symptoms, and to provide a scientific reference for depression prevention in adolescents. Methods Using stratified cluster random sampling method, a total of 2 010 students from 5 middle schools in urban areas and 3 middle schools in suburban counties were selected. Screen time and sleep duration were evaluated through questionnaires, and depressive symptom was assessed by the Center for Epidemiological Studies Depression Scale (CES-D). Results The prevalence of depressive symptoms (CES-D≥16) was 27.71%(557). Logistic regression analysis showed that students with screen time >2 h/d(OR=1.90, 95%CI=1.53-2.37), sleep duration < 7 h/d (OR=2.54, 95%CI=1.88-3.42) were statistically associated with depressive symptoms. stratified analysis showed that, sleep duration of < 7 h/d was associated with increased odds of depressive symptoms, the magnitude among students with screen time >2 h/d(OR=2.46, 95%CI=1.64-3.71) was higher than those with screen time ≤2 h/d(OR=2.35, 95%CI=1.51-3.65). Conclusion High prevalence of depressive symptoms was observed among middle school students in Nanjing. Prolonged screen time and insufficient sleep duration are associated with increased odds of depressive symptoms. Attention should be paid to the mental health of adolescents with the combined exposure of screen-based activities and lack of sleep. -
