Association between weekend catch-up sleep and cardiovascular disease: Evidence from the National Health and Nutrition Examination Surveys 2017-2018.

Abstract

This study aimed to investigate the relationship between the weekend catch-up sleep duration and cardiovascular disease prevalence among adults in the United States. Cross-sectional study. The United States. Participants from the 2017-2018 National Health and Nutrition Examination Survey (NHANES) who were 20years old or older (n=3400). Sociodemographic characteristics, sleep duration (weekday and weekend), and the presence of cardiovascular disease, hypertension, and diabetes were recorded for all participants. Weekend catch-up sleep was defined as sleeping 1hour longer on weekends than on weekdays. Adjusted multivariable logistic regression analysis was conducted to assess the relationship of weekend catch-up sleep with cardiovascular disease. Participants with cardiovascular disease had shorter weekend catch-up sleep than those without cardiovascular disease (P<.01). Participants with weekend catch-up sleep had a lower prevalence of cardiovascular disease (P<.01) than those with no significant change in weekend sleep duration. An adjusted multivariate logistic regression analysis showed that weekend catch-up sleep duration was significantly associated with the prevalence of angina (P=.04), stroke (P<.01), and coronary heart disease (P=.01). Weekend catch-up sleep was associated with reduced cardiovascular disease prevalence when the weekday sleep duration was <6hours (P<.01). A stratified analysis of participants with <6hours of sleep on weekdays showed that weekend catch-up sleep duration (>2hours) was associated with reduced prevalence of cardiovascular disease (P=.01). Our findings indicate that weekend catch-up sleep duration of >2hours is strongly associated with reduced cardiovascular disease prevalence when the sleep duration is <6hours on weekdays.
