社区老年人活动模式的潜在类别及与认知功能的关系

Latent profiles of activity pattern and its relationship with cognitive function among community-dwelling older adults

目的了解社区老年人活动模式的潜在类别,并探讨各类别与认知功能的关系,为针对性干预提供参考。方法采用国际体力活动问卷长卷及蒙特利尔认知评估量表对合肥市3个社区的648名老年人进行调查。结果社区老年人认知功能障碍检出率32.25%(209/648)。社区老年人活动模式可分为活跃型(11.57%)、中等活跃型(52.32%)和久坐型(36.11%);中等活跃型和久坐型老年人认知障碍患病风险显著高于活跃型(均P<0.05)。结论社区老年人活动模式存在异质性,社区卫生保健人员认知功能筛查时应加大活动模式为久坐型老年人的关注度,可通过识别和干预活动模式的潜在类型改善其认知状态,以提升老年人生活质量。

Objective To identify the latent profiles of activity pattern of community-dwelling older adults,and explore the associations of latent profiles of activity patterns and cognitive function,and to provide reference for developing targeted measures.Me-thods A total of 648 older adults from 3 communities in Hefei city were surveyed with the International Physical Activity Questionnaire long-form(IPAQ-LF)and the Montreal Cognitive Assessment.Results The prevalence of cognitive impairment in the community-dwelling older adults was 32.25%(209/648).The activity patterns of older adults were classified into 3 profiles of"active"(11.57%),"moderate-active"(52.32%),and"sedentary"(36.11%).The risk of cognitive impairment in older adults with"mo-derate-active"or"sedentary"activity patterns were higher than those with"active"pattern.Conclusion Activity patterns of community dwelling older adults are heterogeneous.Community healthcare workers should pay more attention to older adults with"sedentary"activity pattern,identify and take interventions targeting their activity patterns to enhance their cognitive function,in an effort to improve quality of life of them.
