Short sleep duration is associated with increased risk of pre-hypertension and hypertension in Chinese early middle-aged females.

Purpose: The aim of this study is to investigate the relationship between sleep duration and hypertension in a middle-aged Chinese population.

Methods: Cross-sectional data of 20,505 individuals aged 35-64 years from Taizhou longitudinal study was used. Logistic regression models were used to calculate odds ratios (ORs) for the risk of pre-hypertension and hypertension in association with sleep duration.

Associations of sleep duration and sleep quality with life satisfaction in elderly Chinese: The mediating role of depression.

This study investigated whether sleep duration and quality were related to life satisfaction (LS) among older Chinese adults and whether depression mediated those relationships. Cross-sectional data from the aging arm of the Rugao Longevity and Aging Study were used. Sleep duration, sleep quality, depression, LS and covariates were analyzed using logistic regressions.
