摘要
目的：本研究旨在探讨体重指数和腰围是否可以调节屏幕时间与青少年心理健康的关系，以及睡眠质量是否可以调节这种关系。方法：采用分层整群随机抽样的方法，从全国6个行政区域抽取13-18岁的青少年5,713人进行问卷调查。数据分析采用Pearson相关分析等统计方法。中介模型采用Hayes开发的PROCESS（3.3版）SPSS宏模型4进行检验，调节模型采用模型7进行检验。结果：屏幕时间与青少年心理健康呈负相关（r = -0.10, p r = 0.03, p β = -0.20, SE = 0.07, p β = -0.89, SE = 0.12, p β = 0.04, SE = 0.01, p r = -0.005, p > 0.05），腰围与心理健康呈负相关（r = -0.04, p > 0.05），睡眠质量不调节屏幕时间与腰围的关系（p > 0.05）。结论：BMI在屏幕时间与青少年心理健康之间起部分中介作用。此外，睡眠质量削弱了看屏幕时间和心理健康之间的联系。因此，建议通过提高睡眠质量来缓解青少年因屏幕时间过长而引起的心理健康问题。
Sleep quality moderated the mediating effect of BMI and waist circumference on the relationship between screen time and mental health in Chinese adolescents.
Objective: This study aimed to investigate whether body mass index and waist circumference can moderate the relationship between screen time and adolescent mental health, and whether sleep quality can moderate these effects.
Method: Using a stratified cluster random sampling method, 5,713 adolescents aged 13-18 years were selected from six administrative regions in China for a questionnaire survey. Data analysis used statistical methods such as Pearson correlation analysis. The mediation model was tested using the PROCESS (version 3.3) SPSS macro model 4 developed by Hayes, and model 7 was used to test the moderation model.
Results: Screen time was negatively correlated with adolescent mental health (r = -0.10, p < 0.001) and positively correlated with BMI (r = 0.03, p < 0.05). Screen time has a significant negative effect on adolescents' mental health [β = -0.20, SE = 0.07, p < 0.01, 95% CI = (-0.34, -0.06)], while BMI mediates the relationship between screen time and mental health [β = -0.89, SE = 0.12, p < 0.001, 95% CI = (-1.11, -0.66)]. Additionally, sleep quality moderates the relationship between screen time and mental health in adolescents [β = 0.04, SE = 0.01, p < 0.001, 95% CI = (0.02, 0.07)]. There was no correlation between screen time and waist circumference (r = -0.005, p > 0.05), but there was a negative correlation between waist circumference and mental health (r = -0.04, p < 0.01). Waist circumference did not mediate the relationship between screen time and mental health (p > 0.05), nor did sleep quality moderate the relationship between screen time and waist circumference (p > 0.05).
Conclusion: BMI plays a partial mediating role between screen time and mental health among Chinese adolescents. Additionally, sleep quality weakens the association between screen time and mental health. Therefore, it is recommended to alleviate mental health issues caused by excessive screen time among adolescents by promoting sleep quality.
