Abstract：Objective To examine the associations of sleep quality with physical activity and sitting time among middle-aged and elderly community populations, so as to provide insights into improving sleep quality among middle-aged and elderly populations. Methods Middle-aged and elderly residents aged 45-69 years were recruited using the convenient sampling method in Changxing County of Zhejiang Province from 2019 to 2020. Participants' demographic characteristics and living behaviors were collected using questionnaires. Sleep quality was evaluated using Pittsburgh Sleep Quality Index, and physical activity level and sitting time were evaluated using Global Physical Activity Questionnaire. The associations of sleep quality with physical activity and sitting time were evaluated using a multivariable logistic regression model. Results A total of 7 170 middle-aged and elderly residents were recruited, including 2 780 men (38.77%). The overall prevalence of poor sleep quality was 8.97%. There were 1 780 (24.83%) participants with a physical activity of 0 to <80 min/week, 1 803 (25.15%) with a physical activity of 80 to <880 min/week, 1 787 (24.92%) with a physical activity of 880 to <9 240 min/week, and 1 800 (25.10%) with a physical activity of 9 240 min/week and longer, and there were 2 535 (35.36%) participants with sitting time of 1 h/d and shorter, 2 259 (31.51%) with sitting time of >1 to 2 h/d and 2 376 (33.14%) with sitting time of over 2 h/d, respectively. Multivariable logistic regression analysis showed that the middle-aged and elderly residents with a physical activity of 880 to <9 240 min/week (OR=0.705, 95%CI: 0.565-0.880) and 9 240 min/week and longer (OR=0.476, 95%CI: 0.364-0.622) had better sleep than those with a physical activity of 0 to <80 min/week after adjustment for gender, age, marital status, annual mean household income, smoking, alcohol consumption and number of chronic diseases, and poorer sleep quality was observed among middle-aged and elderly residents with sitting time of over 2 h/d than among those with sitting time of >1 to 2 h/d (OR=1.303, 95%CI: 1.053-1.613). In addition, the association between sleep quality and physical activity was more significant among women (OR: 0.369-0.734, 95%CI: 0.258-0.950), and the associations of sleep quality with physical activity (OR: 0.427-0.648, 95%CI: 0.282-0.917) and sitting time (OR=1.406, 95%CI: 1.010-1.958) were more significant among participants at ages of 55 to <65 years. Conclusion Poor sleep quality correlates with low-intensity physical activity and long sitting time among middle-aged and elderly populations.
