Abstract

Study objectives: Insufficient/irregular sleep patterns are common conditions, but their cardiovascular consequences and strategies to minimize these risks are poorly explored. We aimed to determine whether weekend sleep extension (catch-up sleep) and social jetlag may impact the incidence of subclinical atherosclerosis.

Methods: We performed a 7-day wrist actigraphy in this cohort study to monitor sleep parameters. Coronary artery calcium (CAC) was measured at two different time points. Catch-up-sleep was measured by calculating weekend minus weekday sleep duration. Social jetlag was calculated by the difference between the mean sleep midpoint on weekend days minus weekdays. The incidence of subclinical atherosclerosis was defined as baseline CAC=0, followed by CAC>0 at the follow-up. The association of incident CAC outcome was assessed using logistic regression adjusting for traditional confounders plus sleep apnea.

Results: We analyzed 1,832 participants (age: 48.8±8.0 years; 57.8% women). Incidence of CAC among subjects with catch-up sleep >90 and ≤90 minutes were 19.1% vs. 31.7%, respectively (P<0.001). In covariate-adjusted analyses (follow-up=5.4±0.90 years), we found a lower incidence of CAC in those participants with catch-up-sleep >90 minutes (OR=0.62; 95% CI 0.52-0.74). Interestingly, stratified analysis revealed that these results are modified by sleep duration (≤6.55 hours: OR=0.42; 95% CI 0.33-0.54; >6.55 hours: OR=0.96; 95% CI 0.75-1.24). In contrast, social jet lag was weakly associated with incident CAC: 0.1% increasing risk/minute.

Conclusions: Extending sleep time during the weekend is independently associated with lower 5-year CAC incidence, providing relevant insights into the cardiovascular benefits of this common sleep habit Worldwide.

期刊介绍： SLEEP® publishes findings from studies conducted at any level of analysis, including: Genes Molecules Cells Physiology Neural systems and circuits Behavior and cognition Self-report SLEEP® publishes articles that use a wide variety of scientific approaches and address a broad range of topics. These may include, but are not limited to: Basic and neuroscience studies of sleep and circadian mechanisms In vitro and animal models of sleep, circadian rhythms, and human disorders Pre-clinical human investigations, including the measurement and manipulation of sleep and circadian rhythms Studies in clinical or population samples. These may address factors influencing sleep and circadian rhythms (e.g., development and aging, and social and environmental influences) and relationships between sleep, circadian rhythms, health, and disease Clinical trials, epidemiology studies, implementation, and dissemination research.
