Abbreviations: CI, confidence interval, ORs, odd ratios.
Regression coefficients or ORs were for an increase in the glucose level of 1 SD (0.4 mmol/l for the fasting glucose level, 1.7 mmol/l for the 1 h glucose level, and 1.4 mmol/l for the 2 h glucose level). Adjusted for maternal age, income, educational level, smoking during pregnancy, second hand smoking exposure during pregnancy, pre-pregnancy BMI, height, family history of diabetes, gender, parity, assisted reproductive technology, gestational week at the OGTT.
