Abstract

Objective: Sleep difficulties in youth have been associated with numerous negative outcomes, such as higher risk of obesity. Though the relationship between sleep and obesity is not well clarified, past research has shown that modifiable health behaviors, such as diet, physical activity, and screen time, may explain this relationship. The purpose of this study was to simultaneously examine these health behaviors as mediators of the relationship between insomnia severity and obesity among a sample of adolescents aged 12-18 years.

Method: English-speaking parents/legal guardians of adolescents were invited to participate in an online survey focused on pediatric sleep patterns, health behaviors, and weight. Parents/guardians (N = 599) reported on their adolescent's diet (i.e., consumption of fruits/vegetables, fast food, and breakfast), physical activity, screen time, and BMI. A multiple mediation analysis was run to test these health behaviors as mediators of the relationship between insomnia severity and BMI, after controlling for sex, age, race, and poverty.

Results: While insomnia was related to most health behaviors, screen time was the only significant mediator of the relationship between insomnia and BMI, after controlling for the effects of the other mediators and all covariates, ab = .04, 95% CrI [.01, .09].

Conclusions: Screen time has implications for both adolescents' sleep health and weight. Pediatric clinicians should systematically assess for, and provide, recommendations on ways to improve sleep and screen time use, in addition to providing traditional dietary and physical activity recommendations.

青少年健康行为对失眠严重程度和肥胖的影响。

目的青少年睡眠困难与许多不良后果有关，例如肥胖风险较高。虽然睡眠与肥胖之间的关系还不十分明确，但过去的研究表明，饮食、体育活动和屏幕时间等可改变的健康行为可能会解释这种关系。本研究旨在同时研究这些健康行为作为失眠严重程度与肥胖之间关系的中介因素在 12-18 岁青少年样本中的作用：方法：邀请讲英语的青少年父母/法定监护人参与一项在线调查，重点关注儿科睡眠模式、健康行为和体重。家长/监护人（N = 599）报告了青少年的饮食（即水果/蔬菜、快餐和早餐的消费）、体育活动、屏幕时间和体重指数。在控制了性别、年龄、种族和贫困程度后，进行了多重中介分析，以检验这些健康行为是否是失眠严重程度与体重指数之间关系的中介：尽管失眠与大多数健康行为有关，但在控制了其他中介因素和所有协变量的影响后，屏幕时间是失眠与体重指数之间关系的唯一显著中介因素，ab = .04, 95% CrI [.01, .09]：结论：屏幕时间对青少年的睡眠健康和体重都有影响。儿科临床医生除了提供传统的饮食和体育锻炼建议外，还应系统地评估改善睡眠和屏幕时间使用的方法，并提供相关建议。
