Abstract
PURPOSE: To investigate the associations between sleep duration and atherosclerotic cardiovascular disease (ASCVD) risk and the potential mechanism. METHODS: Overall, 24,471 subjects without ASCVD were included from Dongfeng-Tongji (DFTJ) cohort. Data collection included questionnaires and general medical examinations. We used logistic regression models and generalized linear models to examine the associations between sleep duration, peripheral white blood cell (WBC) counts, and 10-year ASCVD risk. Mediation analyses were further performed to assess the potential role of peripheral WBC counts in the associations between sleep duration and 10-year ASCVD risk. RESULTS: Increased risk of 10-year ASCVD was observed as sleep duration extended. After adjusting for potential confounders, the odds ratios (ORs) and 95% confidence intervals (CIs) for the risk of 10-year ASCVD were 1.24 (1.11-1.38), 1.12 (1.03-1.22), and 1.21(1.08-1.36) for individuals with nighttime sleeping duration of ≥ 9 h, daytime napping duration of > 30 min, and daily sleep duration of ≥ 9 h, respectively. Peripheral WBC counts mediated 14.1%, 14.5%, and 12.6% in the associations of nighttime sleep duration of ≥ 9 h, daytime napping duration of > 30 min and daily sleep duration of ≥ 9 h with 10-year ASCVD risk, respectively. CONCLUSIONS: Extended sleep durations are associated with the increased 10-year ASCVD risk, and the associations are partially mediated by peripheral WBC counts.
