This study was to investigate the reciprocal relationship between frailty and physical activity among older adults by age group (middle-old: 70-79 years; oldest-old: 80-84 years) within 2 years using cross-lagged panel analysis. The study data were derived from the Korean Frailty and Aging Cohort Study, and a total of 1092 participants were included. Frailty and high physical activity had significant reciprocal relationships in the middle-old group, which indicates that frailty was associated with less high physical activity, and high physical activity predicts less frailty after 2 years. In the oldest-old group, there was no statistically significant reciprocal relationship between frailty and any level of physical activity reference to low physical activity and vice versa after 2 years. Further studies on the relationship between frailty and physical activity of the oldest-old population and specific physical activity guidelines for older adults are needed.
本研究旨在通过交叉滞后面板分析，按年龄组（中老年人：70-79 岁；老年人：80-84 岁）探讨老年人衰弱与身体活动之间的相互关系。研究数据来自韩国衰弱和老龄化队列研究，共纳入 1092 名参与者。在中老年人组中，衰弱与高身体活动之间存在显著的相互关系，这表明衰弱与较少的高身体活动有关，而高身体活动在 2 年后预示着衰弱程度较低。在老年人组中，衰弱与任何水平的身体活动之间均无统计学上显著的相互关系，参考低身体活动和高身体活动也是如此。需要进一步研究老年人中衰弱和身体活动之间的关系，以及为老年人制定特定的身体活动指南。
