Impact of nighttime sleep duration and daytime nap combinations on cardiovascular disease risk in middle-aged and older Chinese adults: a nationwide prospective cohort study

Puntos clave

• Investigate the relationship between sleep duration, napping, and cardiovascular disease (CVD) risk in middle-aged and older adults.
• Nationwide prospective cohort design
• Focused on middle-aged and older Chinese adults
• Assessed combinations of nighttime sleep duration and daytime napping
• Analyzed cardiovascular disease risk outcomes
• Insufficient nighttime sleep combined with daytime napping generally increased CVD risk
• Moderate napping with insufficient nighttime sleep did not elevate CVD risk
• Findings suggest specific sleep patterns influence cardiovascular health
