Disease accumulation across birth cohorts in South Korea.

ABSTRACT:

Objectives

This article estimates rates and age-trajectories of disease accumulation across South Korean birth cohorts and assesses whether observed cohort differences persist after accounting for early-life exposures and adult characteristics.

Methods

Data were from eight waves of the Korean Longitudinal Study of Aging (2006-2020) and included 8,202 participants aged 50 to 74 years. Birth cohorts were defined by historical periods: Japanese annexation (1932-1944), Korean liberation (1945-1949), Korean War (1950-1953), and Post-war (1954-1961). Poisson mixed-effects models were used to estimate disease accumulation using counts of self-reported chronic diseases. Models were built stepwise from a baseline model with cohort fixed effects. Subsequent models added a cohort/age i
