The Clinical Characteristics of Gestational Diabetes Mellitus in Korea: A National Health Information Database Study.

ABSTRACT:

Background

To investigate the clinical characteristics of gestational diabetes mellitus (GDM) in Korea, using a nationwide database.

Methods

We analyzed 417,139 women who gave birth between 2011 and 2015 using the Korean National Health Information Database. They underwent the Korean National Health Screening Program within one year before pregnancy and were not prescribed drugs for diabetes nor diagnosed with diabetes mellitus before 280 days antepartum. Patients with GDM were defined as those who visited the outpatient clinic more than twice with GDM codes.

Results

The prevalence of GDM was 12.70% and increased with increasing maternal age, prepregnancy body mass index (BMI), waist circumference (WC), and fasting plasma glucose (FPG) (P for trend <0.05). As compared with those aged <25 years, the odds ratio for women with GDM aged ≥40 years were 4.804 (95% confidence interval [CI], 4.436 to 5.203) after adjustment for covariates. Women with prepregnancy BMI ≥30 kg/m2 were at 1.898 times (95% CI, 1.736 to 2.075) greater risk for GDM than those with prepregnancy BMI <18.5 kg/m2. Women with WC of ≥95 cm were at 1.158 times (95% CI, 1.029 to 1.191) greater risk for GDM than women with WC of less than 65 cm. High FPG, high income, smoking, and drinking were associated with an elevated risk of GDM.

Conclusion

The prevalence of GDM in Korean women increased up to 12.70% during 2011 to 2015. These data suggest the importance of GDM screening and prevention in high-risk groups in Korea.

Project description:ObjectivesTo evaluate the influence of genetic variants and clinical characteristics on the risk of gestational diabetes mellitus (GDM) and to construct and verify a prediction model of GDM in early pregnancy.MethodsFour hundred seventy five women with GDM and 487 women without, as a control, were included to construct the prediction model of GDM in early pregnancy. Both groups had complete genotyping results and clinical data. They were randomly divided into a trial cohort (70%) and a test cohort (30%). Then, the model validation cohort, including 985 pregnant women, was used for the external validation of the GDM early pregnancy prediction model.ResultsWe found maternal age, gravidity, parity, BMI and family history of diabetes were significantly associated with GDM (OR > 1; P < 0.001), and assisted reproduction was a critical risk factor for GDM (OR = 1.553, P = 0.055). MTNR1B rs10830963, C2CD4A/B rs1436953 and rs7172432, CMIP rs16955379 were significantly correlated with the incidence of GDM (AOR > 1, P < 0.05). Therefore, these four genetic susceptible single nucleotide polymorphisms (SNPs) and six clinical characteristics were included in the construction of the GDM early pregnancy prediction model. In the trial cohort, a predictive model of GDM in early pregnancy was constructed, in which genetic risk score was independently associated with GDM (AOR = 2.061, P < 0.001) and was the most effective predictor with the exception of family history of diabetes. The ROC-AUC of the prediction model was 0.727 (95% CI 0.690-0.765), and the sensitivity and specificity were 69.9% and 64.0%, respectively. The predictive power was also verified in the test cohort and the validation cohort.ConclusionsBased on the genetic variants and clinical characteristics, this study developed and verified the early pregnancy prediction model of GDM. This model can help screen out the population at high-risk for GDM in early pregnancy, and lifestyle interventions can be performed for them in a timely manner in early pregnancy.
