Longitudinal associations of chronic pain severity trajectories and number of pain site trajectories with risk of limitations in ability in daily activities: Evidence from two 10-year prospective cohort studies.

ABSTRACT:

Background and objectives

Chronic pain is a significant risk factor for limitations in activities of daily living (ADL). However, previous studies have mostly assessed pain severity at a single time point, overlooking its temporal variability. This study aims to explore the longitudinal associations between trajectories of chronic generalized pain severity, the number of pain sites, and trajectories of chronic site-specific pain severity with the risk of developing ADL limitations.

Methods

This study utilized longitudinal data from individuals aged 50 and above in two cohorts: the English Longitudinal Study of Ageing (ELSA) and the Korean Longitudinal Study of Aging (KLoSA). By analyzing dynamic changes in pain severity states, trajectories of chronic generalized pain severi
