Regulating Effect of Weekend Catch-up Sleep on Association of Hepatic Steatosis with Atherosclerotic Cardiovascular Disease.

BACKGROUND

Both insufficient and excessive catch-up sleep durations have been implicated in influencing the risk of cardiovascular diseases (CVDs) and metabolic disorders. However, the specific impact of weekend catch-up sleep (WCS) on the relationship between hepatic steatosis (HS) and atherosclerotic cardiovascular disease (ASCVD) remains unclear.

AIMS

This cross-sectional study aims to examine the potential regulatory effect of WCS on the association between controlled attenuation parameter (CAP) and ASCVD.

METHODS

Weighted logistic regression analyses were employed to evaluate the associations of CAP and WCS with ASCVD, expressed in terms of odds ratios (ORs) and 95% confidence intervals (CIs). The study also explored the effect of WCS on the CAP-ASCVD relationship and assessed the potential regulatory role of WCS in subgroups based on age, gender, body mass index, and obesity status.

RESULTS

Eligible participants were categorized into two groups: those with an ASCVD risk < 7.5% (n = 1536) and those with an ASCVD risk ≥ 7.5% (n = 1612). After adjusting for covariates, CAP ≥ 274 dB/m was associated with a higher likelihood of ASCVD compared to the CAP < 274 dB/m (OR, 1.84, 95% CI, 1.24-2.73). When compared to a WCS duration of 0-1 hour, WCS ≥ 1 hour was found to increase the potential ASCVD risk associated with CAP (OR, 3.29, 95% CI, 1.41-7.68). Furthermore, among individuals with WCS ≥ 1 hour, CAP ≥ 274 dB/m was linked to a higher ASCVD risk than among those with CAP < 274 dB/m (OR, 3.72, 95% CI, 1.99-6.93). Additionally, in subgroups of participants aged ≥ 60 years, females, non-obese and obese individuals, WCS ≥ 1 hour was associated with an increased ASCVD risk related to CAP (all, < 0.05).

CONCLUSION

A WCS duration of ≥ 1 hour may be associated with an increased ASCVD risk in adults with HS aged ≥ 40 years. However, further research is necessary to clarify the causal relationships between WCS, HS, and ASCVD.
