The China Health and Retirement Longitudinal Study (CHARLS) is the primary research framework used to investigate the relationship between sleep duration and various health outcomes, including cognitive decline {fact:1, fact:2, fact:3} and hypertension [1]. The study provides specific measurements quantifying how variations in sleep duration impact the risk of cognitive decline {fact:4, fact:5}.

claimThe China Health and Retirement Longitudinal Study (CHARLS) identified a U-shaped relationship between sleep duration and incident cognitive decline (nonlinear, p < 0.001).
measurementWhen sleep duration equaled or exceeded 7.23 hours, an increase in sleep duration significantly elevated the risk of cognitive decline (OR = 1.31, 95% CI: 1.17–1.46) according to the China Health and Retirement Longitudinal Study (CHARLS).
measurementWhen sleep duration was below 7.23 hours, an increase in sleep duration significantly reduced the risk of cognitive decline (OR = 0.90, 95% CI: 0.86–0.95) according to the China Health and Retirement Longitudinal Study (CHARLS).
claimThe China Health and Retirement Longitudinal Study (CHARLS) investigates the association between baseline sleep duration and cognitive decline trajectories among cognitively normal participants using group-based trajectory modeling (GBTM) over a 9-year follow-up period.

referenceGuo et al. (2016) conducted a cross-sectional study using data from the China Health and Retirement Longitudinal Study (CHARLS) 2011-2012, which identified gender- and age-specific associations between sleep duration and prevalent hypertension in middle-aged and elderly Chinese populations.
claimThe 2020 China Health and Retirement Longitudinal Study identified an inverted U-shaped relationship between sleep duration and global cognitive decline, suggesting that cognitive function should be monitored in individuals with both short and long sleep durations.
