Retrospective observational study of the association between changes in physical activity and frailty in middle-aged and older adults: evidence from the Korean Longitudinal Study of Aging (2006-2022).

ABSTRACT:

Objectives

This study aimed to investigate the relationship between changes in physical activity and frailty among middle-aged and older adults in Korea, using panel data from the 2006-2022 Korean Longitudinal Study of Aging (KLoSA).

Design

Retrospective observational study.

Setting

For this longitudinal panel study, data were sourced from the KLoSA dataset.

Participants

We analysed data from 5594 participants (2855 males and 2739 females) extracted from KLoSA data collected between 2006 and 2022.

Primary and secondary outcome measures

The frailty index was calculated based on 6 clinical domains comprising 34 age-related health deficits. Changes in physical activity were categorised as persistently inactive, decreased, increased or persistently active. L
