Effect of Working after Retirement on Sleep Quality in Chinese Older People

Background Chinese aging population degree will transform mild to moderate. During addressing aging issues by proactive national strategies and healthy aging strategies, the sleep health of older peoplecannot be ignored. Objective To explore the effect of working after retirement on sleep quality in Chinese older people, providing relevant reference data for improving sleep quality in this group of people. Methods In August 2021, data of working after retirement prevalence and sleep health in subjects aged ≥60 years (n=7 862) were obtained from the 2018 China Family Panel Studies (CFPS) conducted by Peking University with permission. They were divided into working after retirement and non-working after retirement groups by working after retirement prevalence. Normal sleep duration (within 4 to 10 hoursper night) , abnormal sleep duration (≤4 or ≥10 hours per night) , sleeping late (going to bed after 23 o'clock) in accordance with relevant diagnostic criteria used in international studies on sleep health in middle-aged and older people. Self-reported perceptions of sleep quality were classified into optimistic and pessimistic according to subjective evaluation of sleep efficiency and effect. Binary Logistic regression model was used to explore the effect of working after retirement on sleep duration, perception of sleep quality and the time to go to sleep. Results Among the subjects, 5 705 (72.56%) had optimistic sleep quality, 6 508 (82.78%) had normal sleep duration, and 7 464 (94.94%) went to sleep earlier than 23: 00, and 4 005 (50.94%) still worked after retirement. After controlling for age, gender, maritalstatus, education level, personality traits and other factors, working after retirement was associated with increased probability of higher optimism with sleep quality〔OR (95%CI) =1.205 (1.069, 1.358) 〕, more normal sleep duration〔OR (95%CI) =1.306 (1.137, 1.499) 〕, and earlier time to go to sleep〔OR (95%CI) =1.596 (1.253, 2.033) 〕.Working after retirement was associated with increased probability of good sleep quality (P
