Prevalence of Chronic Diseases by Cognitive Function Level and Age Group Among Middle-Aged and Older Korean Adults.

ABSTRACT:

Objectives

This study aimed to investigate the age-dependent association between new cognitive classification and chronic diseases among middle-aged and older adults using Poisson regression analysis.

Methods

We included 6940 people from the 2018 Korean Longitudinal Study of Aging. Cognitive status was classified as normal, moderate, and severe based on the participants' Korean Mini-Mental State Examination scores and instrumental activities of daily living. Poisson regression analysis was performed to predict the number of chronic diseases in middle-aged and older adults with grade three cognitive status. The number of predicted events at each cognitive level was calculated according to age.

Results

In the normal cognitive group, most of the participants were females
