Association of weekend catch-up sleep, sleep durations and cardiometabolic multimorbidity: Based on NHANES.

BACKGROUND

Cardiometabolic multimorbidity (CMM) is defined as the coexistence of two or more cardiometabolic diseases, including hypertension, diabetes, stroke, and cardiovascular disease. Weekend catch-up sleep (WCS) is an effective repayment of sleep debt, and the association between WCS and CMM, and between WCS and CMM under the influence of average sleep duration, weekday sleep duration, and weekend sleep duration is unknown. The aim of this study was to determine the association between WCS and CMM and their association under different sleep durations.

METHODS

A cross-sectional study was conducted using the 2017-2018 US National Health and Nutrition Examination Survey dataset (N = 3431). Weighted multivariate logistic regression models estimated the odds ratio (OR) and their 95 % confidence interval (95%CI) between WCS and CMM, associations between WCS and CMM under different sleep duration stratifications were examined. A restricted cubic spline plot was used to describe the relationship between various sleep durations, WCS durations, and the prevalence of CMM.

RESULTS

WCS made a statistically significant difference between those with CMM and no-CMM (p < 0.001). After adjusting for covariates, WCS was found to be a protective factor for CMM with OR of 0.531 (0.360, 0.784). After stratified analyses with different sleep durations, it was found that WCS remained a protective factor for CMM in those with different sleep durations <8 h.

CONCLUSION

There was an association between WCS and CMM. WCS was a protective factor for CMM. WCS remained a protective factor for CMM across different sleep durations <8 h.
