Prevalence of Dementia in Korea Based on Hospital Utilization Data from 2008 to 2016.

ABSTRACT:

Purpose

Dementia is an important health issue in Korea due to its associated medical costs. Our study aimed to estimate the prevalence of dementia in Korea by analyzing hospital utilization rates.

Materials and methods

We examined National Health Insurance data from 2008 to 2016 and identified all dementia cases. Crude and ageand sex-standardized prevalence were calculated. A generalized linear mixed model was used to estimate prevalence ratios.

Results

We identified 176746 and 530269 dementia cases in 2008 and 2016, respectively. Alzheimer's disease was the most common dementia subtype (65.4% and 86.1% in 2008 and 2016, respectively). Across all age groups, the prevalence of dementia increased consistently: the increase was prominent among patients ≥85 years of age.
