Prevalence and associated factors of poor sleep quality among Chinese retirees: A multicenter cross-sectional study

Abstract

BackgroundSleep problems are common among older adults worldwide. The present study aims to determine the prevalence of poor sleep quality and its independent factors among retired people in health check-ups population in China. MethodIn this multicenter, cross-sectional survey in 2017, a group of retired people was invited to participate in an online survey of health status, and their data, including socio-demographic information, lifestyle, and medical characteristics, were recorded. Binary logistic regression was used to analyze the independent factors responsible for poor sleep quality. ResultsData from 17,408 responders who met the inclusion criteria were analyzed; among them, 53.04 % (95 % CI = 52 %–54 %) reported poor sleep quality. Binary logistic regression showed that poor sleep quality was associated with a number of factors, including being female (OR = 1.42, 95 % CI = 1.32–1.53), being single (OR = 1.35, 95 % CI = 1.18–1.54), non-smoker (OR = 1.12, 95 % CI = 1.03–1.22), physical inactivity (OR = 1.14, 95 % CI = 1.05–1.23), poor self-rated health status (OR = 1.69, 95 % CI = 1.43–2.00), long-term medication use (OR = 1.05, 95 % CI = 1.07–1.23), chronic pain (OR = 1.33, 95 % CI = 1.22–1.45), comorbidity (OR = 1.16, 95 % CI = 1.07–1.25), and depressive symptoms (mild depression: OR = 2.14, 95 % CI = 1.96–2.34; moderate depression: OR = 4.00, 95 % CI = 3.49–4.58, moderately severe depression: OR = 4.15, 95 % CI = 3.47–4.97, severe depression: OR = 4.27, 95 % CI = 2.93–6.22); while age (OR = 0.99, 95 % CI = 0.99–1.00) was negatively related to poor sleep quality. ConclusionThe prevalence of poor sleep quality in the studied population is relatively high (53.04 %). Sleep problems are common among Chinese retirees, especially older females, and have a great impact on their quality of life. People living with depression, chronic diseases, and chronic pain were at a higher risk of developing sleep disorders. Therefore, it is critical to formulate effective management strategies for Chinese retirees with poor sleep quality in the context of healthy aging.
