Abstract:

Objective ·To compare the physical activities of stroke population and non-stroke population based on the baseline survey of the elderly population cohort in Shanghai communities, and explore the participation in different types of physical activities of stroke population. Methods ·The subjects were screened from Shanghai Community Elderly Cohort constructed from February to August, 2019 according to the admission criteria. The subjects were divided into non-stroke group and stroke group according to whether they had reported a history of stroke by themselves, and the two groups were matched 2 to 1 by controlling age and sex with propensity score matching. The baseline characteristics of the two groups were collected, and the physical activities related to sports, transportation and housework in the last week were investigated with the International Physical Activity Questionnaire (IPAQ). Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep quality of the subjects. Generalized Anxiety Disorder (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) were used to evaluate anxiety and depression of the subjects, respectively. The above characteristics were compared between the stroke group and non-stroke group, and the participation of different types of physical activities were compared between the two groups by multivariate Logistic regression model. Results ·Among the 17 948 people included, there were 993 (5.5%) in the stroke group and 16 955 (94.5%) in the non-stroke group. After propensity score matching, there were 1 984 people (66.7%) in the non-stroke group and 992 people (33.3%) in the stroke group. There were significant differences in education level, pre-retirement occupation, waist circumference, body mass index, sleep status, anxiety symptoms, depression symptoms and disease history between the two groups (all P<0.05). In terms of physical activities, the female stroke group had shorter daily moderate exercises time, fewer riding and walking days in one week, and shorter daily riding time, compared with the non-stroke people, with statistical significance (all P<0.05). Compared with the non-stroke people, the weekly housework days and daily housework time in the male and female stroke groups were lower than those in the non-stroke group, while the daily sedentary time was longer, with statistical significance (all P=0.000). In terms of physical activity level, the proportions of men and women in the stroke group who reached medium or high level were lower than those in the non-stroke group, and the differences were statistically significant (all P=0.000). After adjusting for gender, age, occupation, anxiety symptoms, history of hyperlipidemia, history of atrial fibrillation, history of chronic gastritis and history of hip fracture by multivariate Logistic regression model, the level of vigorous exercise participation in the stroke group was lower, the proportions of no housework in the last week and sedentary time greater than 180 min per day were higher, and the proportion at medium and high activity levels was lower (all P<0.05). Conclusion ·The frequency and duration of housework participation and the physical activity level of elderly people with a history of stroke in Shanghai communities are at a lower level than those without stroke, and they also have a longer sedentary time.
