Table 5 Results of the multiple logistic regression analysis to investigate the factors associated with the postpartum development of diabetes: The continuous variable model (n = 269)a

From: Risk factors associated with the development of postpartum diabetes in Japanese women with gestational diabetes

Variables included in the multivariate models Model 1 Model 2b
RR 95% CI P value RR 95% CI P value
Pre-pregnancy BMI (kg/m2) 1.04 0.96–1.13 0.29 1.08 0.98–1.20 0.13
2-h PG (mg/dl) 1.02 1.00–1.03 0.042 1.02 1.00–1.04 0.030
HbA1c (%) 5.38 1.64–19.06 0.0069 5.04 1.27–22.0 0.021
Insulin therapy during pregnancy (%) 1.92 0.71–5.78 0.22 1.92 0.66–6.46 0.24
  1. a We used data from 269 women who had HbA1c test results available at the time of the diagnostic OGTT during pregnancy
  2. b Adjusted for the maternal age, parity, family history of diabetes, GA at OGTT, fasting and 1-h PG, weight gain during pregnancy, and follow-up period
  3. RR relative risk, BMI body mass index, PG plasma glucose, OGTT oral glucose tolerance test, GA gestational age
