Table 2. Interaction of overweight and other factors at the first prenatal visit (FPV) on the risk of gestational diabetes (GDM).
Odds ratios of every 1 standard deviation increase in risk factors for GDM were shown.
| BMI<24 | BMI≥24 | p value of the interaction | |
|---|---|---|---|
| Age | 1.36* | 1.94* | 0.289 |
| FPG at FPV | 2.02* | 2.42* | 0.720 |
| HbA1c at FPV | 1.60* | 4.02* | 0.025* |
| ln HOMA2-IR at FPV | 1.78* | 1.87 | 0.946 |
| ln TG at FPV | 1.64* | 1.22 | 0.266 |
| SBP at FPV | 1.14 | 1.79* | 0.213 |
| DBP at FPV | 1.03 | 2.26* | 0.022* |
FPG, fasting plasma glucose; HbA1c, hemoglobin A1c; ln, nature logarithm transformation; TG, plasma triglyceride; SBP, systolic blood pressure; DBP, diastolic blood pressure.
