| Macrosomia |
LGA |
|||
|---|---|---|---|---|
| OR (95% CI) | p value | OR (95% CI) | p value | |

| Model 1 | 1.14 (1.01–1.28) | 0.0308 | 1.11 (0.99–1.24) | 0.0593 |
| Model 2 | 1.17 (1.04–1.32) | 0.0109 | 1.12 (1.00–1.27) | 0.0569 |
| Model 3 | 1.15 (1.02–1.30) | 0.0271 | 1.10 (0.98–1.25) | 0.1225 |
| Model 4 | 1.15 (1.02–1.30) | 0.0214 | 1.11 (0.99–1.25) | 0.0980 |
| Prepregnancy BMI ≥24 kg/m2 versus <24 kg/m2 | ||||
| Model 1 | 2.37 (2.11–2.66) | <0.0001 | 2.39 (2.14–2.67) | <0.0001 |

Model 1: univariable analysis. Model 2: multivariable analysis, adjusted for age, height, parity, education >12 years, gestational age at delivery (only for macrosomia), gender (only for macrosomia), weight gain from pre-pregnancy to GCT, insulin treatment, alcohol drinker during pregnancy, multiple pregnancies, and systolic blood pressure at first antenatal care visit. Model 3: further adjusted for GDM, in addition to the variables listed in model 2. Model 4: further adjusted for GCT value, in addition to the variables listed in model 2. BMI, body mass index; OR, odds ratio; CI, confidence interval; GDM, gestational diabetes mellitus; GCT, glucose challenge test; LGA, large for gestational age.
