Objective: 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. Methods: 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 (≤5 h/day<6h/day), normal (6–8 h/day), and long (≥9 h/day>8h/day). Multivariate logistic regression was used to examine associations between sleep duration and CAD, adjusting for demographic and clinical confounders. Results: Short sleep (≤5 h/day<6h/day; OR=1.595, 95% CI=1.230–2.067) and long sleep (≥9 h/day>8h/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. Conclusion: Both short and long sleep durations are significant risk factors forcoronary 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.
