Correlation of Income Instability With 12 Non-Communicable Disease Risks in Korea: A Prospective Cohort Study.

ABSTRACT:

Background

Due to the lack of comprehensive longitudinal studies examining the impact of long-term volatility on health issues, existing research primarily focused on income levels rather than fluctuation. Thus, we aimed to investigate the relationship between income instability and a range of physical health conditions using an extensive longitudinal dataset.

Methods

This study utilized data from the Korean Genome and Epidemiology Study (KoGES) Ansan-Anseong cohort (2001-2022), which includes valuable confounding factors such as demographic, socioeconomic, lifestyle, and clinical factors. Income volatility was calculated as the intra-individual standard deviation of income changes across study waves. A Cox proportional hazards model was employed to assess correlations betwe
