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.
