Association of sleep problems and sleep duration with self-rated health and grip strength among older adults in India and China: results from the study on global aging and adult health (SAGE)

Abstract

Background Sleep is an important predictor of health and quality of life. This study examined the association between sleep problems and sleep duration with self-rated poor health and grip strength among respondents aged 50 years and above in India and China. Methods: The data for this study were derived from the first wave of WHO’s Study on Global Aging and Adult Health (SAGE), a nationally representative panel survey conducted in six LMICs. Grip strength and poor self-rated health were the main outcome variables, while sleep problems and sleep duration were the main predictors. Multivariate logistic regression models and ordinary least squares regression models were used to understand the association between sleep problems and sleep duration with poor self-rated health and grip strength.
