Poor sleep duration and E-cigarette/Cigarette use among US adults with cardiovascular diseases: findings from the 2022 BRFSS cross-sectional study.

BACKGROUND

Studies have explored the connections between tobacco use, sleep and cardiovascular disease (CVD) risks in adults, but no study has examined the link between tobacco use and sleep among adults with CVDs. This study explores the association between tobacco use (cigarette only, e-cigarette only, and dual use) and poor sleep duration among adults with CVDs.

METHODS

A sample of 47,180 US adults with CVDs (myocardial infarction, coronary heart disease, or stroke) was drawn from the 2022 Behavioral Risk Factor Surveillance System (BRFSS) cross-sectional survey. Poor/inadequate sleep (< 7 h/24-hour) was defined based on National Sleep Foundation recommendations. Logistic regression models assessed tobacco use status across seven categories (i.e., non-use [reference], current [past-month use] cigarette only, current e-cigarettes only, current dual use, former cigarette only, former e-cigarette only, and former dual use) with inadequate sleep, adjusting for demographics and health conditions.

RESULTS

Overall, 40% of US adults with a history of CVD reported inadequate sleep. Current cigarette, e-cigarette, and dual use were associated with a relatively higher proportion of inadequate sleep duration. Unweighted findings revealed a significant association between current cigarette use (OR = 1.35, 95%CI: 1.26-1.44), e-cigarette use (1.40 [1.19-1.63]) and dual use (1.50 [1.27-1.77]) and increased odds of reporting inadequate sleep among adults with CVDs. Weighted analysis showed only a significant link between current cigarette use and inadequate sleep (1.34 [1.17-1.54]).

CONCLUSIONS

Current cigarette use is associated with poor sleep in adults with CVDs. Unweighted findings suggested a similar association for e-cigarettes. Interventions targeting smoking cessation may offer promising avenues for improving sleep health and reducing the burden on adults with CVDs.
