dc.description.abstract	OBJECTIVE: This study aims to assess the association between sleep and successful aging among Chinese ≥60 years of age. METHODS: Data were collected from the baseline survey of the China Health and Retirement Longitudinal Study. Two self-reported questions about sleep quality and duration were examined. Successful aging was defined following Rowe and Kahn's multidimensional model. To assess the adjusted association between sleep and successful aging, multivariable logistic regression was applied. RESULTS: The average number of self-reported hours of sleep was 6.2 ± 2.0 among older Chinese people. Successful aging was related to sleep duration, with the proportion of those adults considered to be aging successfully falling into the following sleep duration categories (<6 h - 7.8%; 6 h - 16.3%; 7 h - 19.1%; 8 h - 14.7%; and ≥9 h - 12.8%). The plots between sleep duration and successful aging were an inverse U-shape. Participants who slept less than 6 h per day had lower odds ratios of successful aging [odds ratio (OR) = 0.52, 95% confidence interval (CI) 0.40-0.67] relative to those who slept for 7 h per day. Compared with those who reported poor sleep less than once a week, older people who reported poor sleep five to seven days a week showed a lower ratio of successful aging (OR = 0.29, 95% CI 0.21-0.39). CONCLUSION: Older age, shorter or longer sleep, and poor sleep were related to lower odds of, rates of successful aging. Most older Chinese adults experience insufficient sleep and poor sleep quality, which could be an important influential factor in successful aging.

Abstract:

OBJECTIVE: This study aims to assess the association between sleep and successful aging among Chinese ≥60 years of age. METHODS: Data were collected from the baseline survey of the China Health and Retirement Longitudinal Study. Two self-reported questions about sleep quality and duration were examined. Successful aging was defined following Rowe and Kahn's multidimensional model. To assess the adjusted association between sleep and successful aging, multivariable logistic regression was applied. RESULTS: The average number of self-reported hours of sleep was 6.2 ± 2.0 among older Chinese people. Successful aging was related to sleep duration, with the proportion of those adults considered to be aging successfully falling into the following sleep duration categories (<6 h - 7.8%; 6 h - 16.3%; 7 h - 19.1%; 8 h - 14.7%; and ≥9 h - 12.8%). The plots between sleep duration and successful aging were an inverse U-shape. Participants who slept less than 6 h per day had lower odds ratios of successful aging [odds ratio (OR) = 0.52, 95% confidence interval (CI) 0.40-0.67] relative to those who slept for 7 h per day. Compared with those who reported poor sleep less than once a week, older people who reported poor sleep five to seven days a week showed a lower ratio of successful aging (OR = 0.29, 95% CI 0.21-0.39).
