Background: Obesity compromises the health of a woman’s pregnancy and her newborn. Aim: To describe weight-gaining changes throughout pregnancy and evaluate outcomes for the mother and the baby. Methods: A retrospective review of women who delivered singletons using a Large perinatal registry was undertaken. Based on their body mass index (BMI), patients were categorized into four categories: underweight, normal, overweight, and obese. Mode of delivery, gestational diabetes, hypertensive disorders, obstetric cholestasis, and postpartum hemorrhage (PPH) were the main maternal outcome measures. The newborn outcome indicators were birth weight, neonatal intensive care unit (NICU) hospitalization, premature birth, and stillbirth. Results: The study sample included 2,352 natives (25.0%) and 7,058 expatriates (75.0%). Most of the sample (4,726) were aged 20-29; 43.6% were aged 30-39; 2.1% were aged 19; and 3.9% were aged 40 years. The incidence of hypertension, obstetric cholestasis, diabetes, postpartum hemorrhage, and cesarean section varied among the sample. In the underweight group, the incidence of cesarean section (C.S.) was 15.7%; in the normal weight group, 24.9%; in the overweight group, 31.3%; and in the obese group, 41.0%. Hypertensive disorders were three times more prevalent in obese women than in normal-weight women (2,0%), and 5.3% of obese women had PPH compared to 5.6% of women of normal weight. The underweight group gained the most weight during pregnancy, whereas the obese group gained the least. Conclusions: A significant proportion of pregnant women in our sample will become obese by delivery. Obesity during pregnancy is associated with adverse maternal and fetal outcomes.
