Cardiovascular disease (CVD) is a leading cause of death worldwide, and several studies have attempted to identify its risk factors. This study aimed to investigate the association between sleep duration and sleep quality, and the 7-year incidence of CVD among middle-aged and older Chinese individuals. A total of 6682 participants aged 45-90 years from the China Health and Retirement Longitudinal Study database were included in this study. The authors estimated sleep duration and quality based on self-reported data of night sleep hours and disturbance symptoms, and examined the associations between them and the composite outcome of CVD using logistic regression models. A total of 1692 participants (25.32%) reported new CVD events during follow-up. Short sleep duration (< 6 h/night) was significantly associated with a higher risk of CVD in all three models (p < .05). However, this was not observed for long sleep duration (> 8 h/night). Additionally, participants with mild sleep disturbance in all three models, and severe sleep disturbance in Models 2 and 3 had a significantly higher risk of CVD (p < .05). After stratification by age and daytime napping, we still found a significant association between short sleep duration and CVD in individuals aged 45-59 years, and between sleep disturbance and CVD in non-nappers (p < .05). However, these associations were not significant in individuals aged ≥60 years or in nappers (p > .05). In conclusion, short sleep duration and sleep dist...
