Gestational diabetes in Korea: Temporal trends in prevalence, treatment, and short-term consequences from a national health insurance claims database between 2012 and 2016

초록

Aims: This population-based cross-sectional study aimed to investigate recent trends in the prevalence and treatment of gestational diabetes mellitus (GDM) in Korea. We also investigated trends in annual prevalence rate of pregnancy-induced hypertension (PIH) and cesarean section (C-section) in GDM patients. Methods: We used data from the Health Insurance Review and Assessment-National Patient Sample (HIRA-NPS) database, 2012-2016. Non-GDM (n = 53,698) and GDM (n = 7956) patient data were analyzed for each year. Results: The annual increase in the prevalence of GDM was 11.1% over 2012-2016, with a significant continuously increasing trend (p < 0.0001). Age-stratified analysis showed that the annual prevalence of GDM significantly increased in patients below 40 years of age, but was not statistically significant as an increasing trend in patients above 40 years of age. Annual PIH prevalence rate among GDM women showed decreasing trend but was not statistically significant. An annual increase in C-section rate above 5% in GDM patients was statistically significant in both unadjusted and adjusted for age and PIH models. Conclusions: The prevalence of GDM in Korean women and C-section rates in women with GDM showed a significantly increasing trend, 2012-2016. There is a need for further efforts to monitor this trend and to identify associated risk factors for GDM in Korean women. (C) 2020 Elsevier B.V. All rights reserved.
