Association between outdoor artificial light at night and metabolic diseases in middle-aged to older adults-the CHARLS survey.

ABSTRACT:

Introduction

Artificial light at night (LAN) is associated with metabolic diseases, but its precise relationship is still not fully understood. This study explores the association between LAN and metabolic diseases.

Methods

A cross-sectional study involving 11,729 participants conducted in 2015 was selected from the China Health and Retirement Longitudinal Study. Diabetes, metabolic syndrome (MetS), overweight, obesity, dyslipidemia, and hyperuricemia (HUA) were defined according to established guidelines.

Multivariate logistic regression models were used to assess the relationship between LAN and metabolic diseases. To investigate pos
