PURPOSE
The rapidly increasing older adults' population of South Korea has increased the socioeconomic burden on society due to cognitive decline. In this study, we examined the association between changes in physical activity in the older adults and their cognitive function, a primary criterion for the diagnosis of dementia, using panel data from the 2012-2018 Korean Longitudinal Study of Aging.
PATIENTS AND METHODS
This study used baseline (2012) and biennial assessment of follow-up data (2014, 2016, 2018) from Korean Longitudinal Study of Aging. A total of 1733 older adults with the Korean version of the Mini Mental State Examination (K-MMSE) scores in the normal range at the time of the first investigation were included in the study. Physical activity was classified into three categories: inactivity, low physical activity, and high physical activity. Changes in physical activity from 2012 were classified into five groups: remained active, became active in 2016, became active in 2014, became inactive, and remained inactive. Participants' general and health-related characteristics were used as control variables. Descriptive statistics, chi-square tests, and logistic regression analysis were used for analysis.
RESULTS
The baseline mean age of the older adults in 2012 was 71.63 years; of the total 1733 participants, 57.1% were inactive, 5.7% had low physical activity, and 37.3% had high physical activity. Changes in physical activity were significantly associated with cognitive decline. Compared to the group that continued regular physical activity, the risk of cognitive decline increased in the case of participants who became or remained inactive.
CONCLUSION
Results highlighted the importance of continuous physical activity and its relation to cognitive function. Encouraging continuous physical activity in the older adults has a positive effect on the prevention of cognitive impairment and dementia. Thus, exercise-based interventions should be implemented a community health service.
目的
韩国老年人口迅速增加，认知能力下降给社会带来了社会经济负担。在本研究中，我们利用2012 - 2018年韩国老年纵向研究的面板数据，研究了老年人身体活动变化与其认知功能（痴呆诊断的主要标准）之间的关联。
患者与方法
本研究使用了韩国老年纵向研究的基线（2012年）数据以及随访数据的两年一次评估（2014年、2016年、2018年）。共有1733名老年人纳入研究，他们在首次调查时韩国版简易精神状态检查表（K-MMSE）得分处于正常范围。身体活动分为三类：不活动、低身体活动和高身体活动。2012年以来身体活动的变化分为五组：保持活跃、2016年变得活跃、2014年变得活跃、变得不活跃以及保持不活跃。参与者的一般特征和健康相关特征用作控制变量。采用描述性统计、卡方检验和逻辑回归分析进行分析。
结果
2012年老年人的基线平均年龄为71.63岁；在总共1733名参与者中，57.1%不活动，5.7%身体活动低，37.3%身体活动高。身体活动的变化与认知能力下降显著相关。与持续进行规律身体活动的组相比，变得不活跃或保持不活跃的参与者认知能力下降的风险增加。
结论
结果凸显了持续身体活动的重要性及其与认知功能的关系。鼓励老年人持续进行身体活动对预防认知障碍和痴呆有积极作用。因此，应在社区卫生服务中实施基于运动的干预措施。
