What is already known about this topic? Comprehensive data characterizing sleep patterns across China’s diverse population remain scarce. What is added by this report? Among Chinese residents aged 15 years and older, this study found a mean sleep duration of 7.24 95% confidence interval (CI): 7.16, 7.32 hours, a mean sleep latency of 27.45 (26.39, 28.51) minutes, a mean bedtime of 22:08 (21:58, 22:18), and a mean wake-up time of 6:18 (6:06, 6:30). Sleep patterns varied considerably across age groups and other demographic characteristics. What are the implications for public health practice? Rather than adopting uniform guidelines, public health interventions should implement tailored, context-specific sleep strategies that effectively address the distinct needs of diverse population groups.
