Objective:

This study examined the mediation roles of multiple lifestyle factors in school-aged children. Structural equation modeling (SEM) tested how lifestyle factors play mechanism roles one another in the impact of ADHD to seek theoretical and intervention insights.

Method:

An online survey assessed children’s lifestyle factors including diet, physical activity, screen time, sleep difficulties, and having ADHD diagnosis. A multi-country sample from English speaking nations included 309 caregivers. Multiple regression and SEM were planned to identify significant correlates and mediators of ADHD in explaining lifestyle differences.

Results:

Preliminary multiple regression showed only sleep quality was significantly different between children with and without ADHD. Significant triple mediation effects suggested diet, physical activity, and screen time mediated the ADHD impact on sleep quality.

Conclusion:

Researchers and practitioners may incorporate the findings to develop intervention models for children with ADHD attending to the mediational roles of lifestyle factors to improve sleep quality.

饮食、体力活动和更好地睡眠的屏幕时间：有和没有注意力缺陷多动障碍的学龄儿童生活方式因素的多重中介分析。

客观的：

本研究考察了多种生活方式因素在学龄儿童中的中介作用。结构方程模型 (SEM) 测试了生活方式因素如何在 ADHD 的影响中相互发挥机制作用，以寻求理论和干预见解。

方法：

一项在线调查评估了儿童的生活方式因素，包括饮食、身体活动、屏幕时间、睡眠困难和多动症诊断。来自英语国家的多国样本包括 309 名护理人员。多元回归和 SEM 旨在确定 ADHD 的显着相关性和中介因素，以解释生活方式差异。

结果：

初步多元回归显示，患有和未患有 ADHD 的儿童之间只有睡眠质量存在显着差异。显着的三重中介效应表明饮食、身体活动和屏幕时间介导了 ADHD 对睡眠质量的影响。

结论：

研究人员和从业者可能会结合这些发现，为 ADHD 儿童开发干预模型，关注生活方式因素的中介作用，以改善睡眠质量。
