Results of logistic regression for low birth weighta in 691 pregnancies in South Korea.
| Unadjusted | Model 1 | Model 2 | |
|---|---|---|---|
| Prenatal depressionb | 2.939 (1.139–7.583) | 1.788 (0.646–4.945) | 1.658 (0.548–5.017) |
| Gestational age | – | 0.209 (0.114–0.383) | 0.180 (0.092–0.350) |
| Maternal pre-pregnancy body mass index | – | – | 0.774 (0.585–1.024) |
| Maternal smoking history | – | – | 1.475 (0.271–8.032) |
| Maternal drinking during pregnancy | – | – | 0.995 (0.199–4.982) |
| Female sex | – | – | 1.835 (0.627–5.368) |
| Cesarean section | – | – | 1.164 (0.384–3.523) |
Data are odds ratio (95% confidence interval). Model 1: adjusted for gestational age. Model 2: adjusted for gestational age, maternal pre-pregnancy body mass index, maternal smoking history, maternal drinking during pregnancy, female sex of the offspring, and delivery by Cesarean section. Dashes indicate that the variable was not included in the model.
a
Low birth weight was defined as birth weight <2500 g.
b
Prenatal depression was defined as a Center for Epidemiologic Studies Depression Scale-10 score ≥10 in the third trimester.
