Outline
To understand the status of physical activity, cognitive impairment, depression, and their comorbidity in elderly people in Chengdu, Sichuan, and to explore the association between physical activity and the comorbidity of cognitive and depressive disorders.
A cluster sampling method was used to select 8 108 elderly individuals in Chengdu. The Chinese version of the Physical Activity Scale for the Elderly, the Short Form of the Geriatric Depression Scale, and the Mini-Mental State Examination were used for evaluation. Binary logistic regression analysis was conducted to examine the association between different dimensions of physical activity, sedentary behavior, and the comorbidity.
The study found that 2 195 participants (27.3%) had cognitive impairment, 802 participants (9.9%) had depression, and 303 participants (3.8%) had both cognitive impairment and depression. The elderly engaging in more than 150 minutes of moderate-intensity household chores per week, more than 150 minutes of moderate-intensity leisure exercises, or more than 210 minutes of transportation-related physical activity per week were significantly negatively correlated with comorbidity. On the other hand, sitting for more than 480 minutes per day was significantly positively correlated with comorbidity.
Participation in physical activity among the elderly is significantly associated with the comorbidity of cognitive and depressive disorders. Promoting moderate-intensity household chores, leisure exercises, and transportation-related physical activities, while reducing sedentary behavior, can help prevent the occurrence of comorbidity.
