Short sleep duration (<6 h/day) increased odds of coronary artery disease by 59.5% (OR 1.595) and long sleep duration (>8 h/day) increased odds by 128.4% (OR 2.284) compared to normal sleep (6-8 h/day) among adults in Chongqing, China.

Does short or long sleep duration increase the prevalence of coronary artery disease in adults?
2,275 adults (aged 31–96) who participated in community medical examinations in Chongqing, China, between August 2018 and October 2020. Key exclusion: missing or inaccurate data.
Short sleep duration (<6 h/day) and long sleep duration (>8 h/day), self-reported
Normal sleep duration (6–8 h/day), self-reported
Prevalence of coronary artery disease (CAD), defined as myocardial infarction, acute coronary syndrome, chronic stable angina, or coronary artery stenosis greater than 50%hard clinical
Both short (<6 hours) and long (>8 hours) sleep durations are significantly associated with an increased prevalence of coronary artery disease, highlighting abnormal sleep duration as a key cardiovascular risk factor.
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 (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. Results 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. Conclusion 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.

Jie He (Mon,) conducted a cross-sectional in Adults aged 31-96 in Chongqing, China undergoing community medical examinations (n=2,275). Short and long sleep duration vs. Normal sleep duration (6-8 hours/day) was evaluated on Prevalence of coronary artery disease (CAD), defined as myocardial infarction, acute coronary syndrome, chronic stable angina, or coronary artery stenosis >50% (OR 1.595 for short sleep (<6 h/day) and OR 2.284 for long sleep (>8 h/day) vs. normal sleep, 95% CI 95% CI 1.230–2.067 for short sleep; 95% CI 1.456–3.583 for long sleep, p=<0.01). Short sleep duration (<6 h/day) increased odds of coronary artery disease by 59.5% (OR 1.595) and long sleep duration (>8 h/day) increased odds by 128.4% (OR 2.284) compared to normal sleep (6-8 h/day) among adults in Chongqing, China.
