Association between indoor light at night and obesity among children and adolescents at different physical activity levels: a population-based cross-sectional study.

ABSTRACT:

Background

Light at night (LAN) has been reported to be related to a variety of metabolic diseases, especially in adults. This study aimed to investigate the association between indoor LAN exposure and obesity-related parameters among children and adolescents, and to assess this association at different levels of physical activity.

Methods

From April to December 2024, LAN exposure was collected by a portable illuminance meter over one week on 628 children and adolescents aged 9-15 years in Shanghai. Obesity-related parameters were measured by body composition analyzer and professional technicians. Moderate-to-vigorous intensity physical activity (MVPA) was assessed using Children' s Leisure Activities Study Survey-Chinese edition (CLASS-C).
