Trajectories of Instrumental Activities of Daily Living and Their Predictors among Older Men and Women in Hong Kong: A 14-Year Prospective Study.

ABSTRACT:

Introduction

This study aimed to identify the different patterns of trajectories in instrumental activities of daily living (IADL) in older men and women, respectively, and to examine the factors associated with the different trajectories.

Methods

We included 2,088 participants with an average age of 70.8 years at baseline from the MrOS and MsOS Hong Kong cohort study (men: 1,074; women: 1,014) and followed up the participants for over 14 years. The group-based trajectory models were used to identify IADL trajectories. Binary logistic regression and multinominal logistic regression models were used to identify factors associated with different trajectories.

Results

Two distinct trajectories were identified for men including "slow decliners" (92.6% of men) and "rapid d
