# Sleep duration and prevalence of coronary artery disease among adults in Chongqing, China

## TL;DR

This study found that both short and long sleep durations are linked to a higher risk of coronary artery disease in adults in Chongqing, China.

## Contribution

The study identifies sleep duration as a modifiable risk factor for CAD in a specific Chinese population.

## Key findings

- Short sleep (<6 hours/day) increased CAD risk by 59.5% compared to normal sleep.
- Long sleep (>8 hours/day) increased CAD risk by 128.4% compared to normal sleep.
- Long sleep duration showed a stronger association with CAD than short sleep.

## Abstract

This study aimed to explore the association between sleep duration and prevalence ofcoronary artery diseases (CAD) among adults in Chongqing, China, and discuss implications for clinical practice and public health policy.

Baseline variables were collected from 2,320 adults who participated in community medical examinations in Chongqing, China, between August 2018 and October 2020. Sleep duration was self-reported and categorized into short (<6 h/day), normal (6–8 h/day), and long (>8 h/day). Multivariate logistic regression was used to examine associations between sleep duration and CAD, adjusting for demographic and clinical confounders.

Short sleep (<6 h/day; OR = 1.595, 95% CI = 1.230–2.067) and long sleep (>8 h/day; OR = 2.284, 95% CI = 1.456–3.583) were significantly associated with increased odds of CAD compared to normal sleep duration (6–8 h/day), even after adjusting for confounders. Long sleep duration demonstrated a notably stronger association with CAD risk.

Both short and long sleep durations are significant risk factors for coronary artery diseases, with longer sleep duration showing a stronger association. Public health initiatives and clinical practices should integrate sleep duration assessments to identify at-risk populations and implement targeted interventions.
