Trajectories of Alzheimer's Disease Prevalence among National Health Insurance and Medical Aid Beneficiaries from 2010 to 2019.

ABSTRACT:

Purpose

Alzheimer's disease (AD) is the leading cause of dementia and is associated with various socioeconomic factors. This study aimed to ascertain the differences in AD prevalence based on healthcare coverage type as a proxy of socioeconomic status in South Korea.

Materials and methods

We examined Health Insurance Review and Assessment Service claims from 2010-2019, identifying AD as the main disease. Crude prevalence rate and age- and sex-standardized prevalence were estimated from healthcare utilization data. Subgroup analysis by age, sex, comorbidities (hypertension, diabetes, and cardiovascular disease), and type of healthcare coverage [Medical Aid (MA) vs. National Health Insurance (NHI)] was performed to estimate the standardized prevalence rate ratio (PRR).
