| 其他摘要 | It has been proved that older adults' exercise habits can have a positive influence on their cognitive function. As a healthy way of life, sports have gradually become an important part of national daily life, most of the older adults in our country have the habit of exercise. Among the older adults, whether exercise habits affect the cognitive function or not, previous studies mainly focus on the overall cognitive function. However, few studies focus on the influence of exercise habits on older adults' specific cognitive function, and the research on exercise frequency and exercise duration is less involved. Based on this, based on verifying the relationship between exercise habits and the older adults' overall cognitive function, this study investigated the influence of exercise habits on older adults' specific cognitive function. It made a detailed analysis of whether exercise frequency and exercise duration affect older adults' cognitive function.In this study, 732 subjects without cognitive impairment were randomly sampled from older adults in three Beijing districts. First of all, the basic information and exercise habits of the older adults were investigated by questionnaire, and the Self-Rating Anxiety Scale, Geriatric Depression Scale, and Social support rating scale were used to evaluate the level of anxiety, depression, and interpersonal relationship. Then, the cognitive function of the older adults was assessed by the Mini-mental State Examination and the Beijing Version of the Montreal Cognitive Assessment. According to whether there is an exercise habit or not, the community-dwelling older adults are divided into an exercise group (n = 625) and a non-exercise group (n = 107). About the exercise frequency of each subject in the exercise group, according to whether the exercise frequency is more than three times a week, the subjects are divided into the high-frequency group (n = 584) and low-frequency group (n = 41); About the exercise duration of each subject in the exercise group, according to whether the exercise duration is more than ten years, the subjects are divided into continuous exercise 10 years or more group (n = 449) and constant exercise 10 years or less group (n = 176). The influence of exercise habits on the cognitive function of the community-dwelling older adults was investigated by comparing the cognitive test scores of the exercise group and the non-exercise group, the high-frequency group and the low-frequency group, the continuous exercise group of 10 years or more and the constant exercise group of fewer than ten years in the four dimensions of overall cognitive function: visual space and orientation ability, speech ability, memory ability and execute and control ability.The result shows: (1) The scores of cognitive function and visual space and orientation ability in the exercise group were higher than those in the non-exercise group, and there was no difference in the scores of speech ability, memory ability, and execute and control ability between the two groups. (2) There was no difference in the general cognitive function scores and specific cognitive function between the high-frequency and low-frequency groups. (3) The score of cognitive function in the group of 10-year exercise or more was higher than that in the group of less than 10-year, and there was no difference in the scores of specific cognitive function between the two groups.The above indicates that the community-dwelling older adults with exercise habits have a better overall cognitive function and visual space and orientation ability, and the overall cognitive function is related to the higher duration of exercise, suggesting that the older adults with exercise habits and exercise habits last for a long number of years, which can promote the cognitive function of the community-dwelling older adults. |
