The Dynamic Associations of Social and Intellectual Activity With Frailty Trajectory in Middle-Aged and Older Adults in China: Nationwide Longitudinal Study.

ABSTRACT:

Background

Research on the effects of social and intellectual activities on frailty remains limited, particularly longitudinal studies examining how these activities influence the dynamic progression of frailty over time. We aimed to examine this association in a nationally longitudinal study.

Objective

This study aimed to investigate the relationship between social and intellectual and frailty trajectories in the middle-aged and older Chinese population. Specifically, it sought to identify distinct frailty trajectories and quantify the longitudinal protective effects of social and intellectual activities against adverse frailty progression, while exploring differential impacts across age, sex, and residence subgroups.

Methods

This study used data from the China Healt
