Abstract

Objective: We investigated whether, in the Korean population, the risk of premature ovarian insufficiency (POI) and early menopause varies with a woman's socioeconomic status, evaluated in relation to income, education, and occupation. Methods: This cross-sectional, population-based study involved 31,508 women aged >19 years registered in the Korea National Health and Nutrition Examination Survey (KNHANES) (2007–2016). Menopausal status and socioeconomic status were obtained from self-reported KNHANES data. A logistic regression model was applied to test whether POI and early menopause varied with socioeconomic status. Results: The prevalence of POI was 2.41% and of early menopause was 5.89%. The annual incidence of POI during the investigation period plateaued, while that of early menopause showed a linear trend. The risk of POI was significantly higher among participants with lower household incomes (odds ratio [OR], 95% confidence interval [CI]; 1.44, 1.16–1.78) and lower levels of education (OR, 95% CI: 1.75, 1.16–2.65) after adjustment for age. Conclusion: The prevalence of POI in the Korean population was almost twice that reported in a previous study. Lower socioeconomic status was associated with an increased risk of POI and early menopause. Further studies are warranted to investigate this association.
