PRE-PREGNANCY BODY MASS INDEX AND WEIGHT GAIN DURING PREGNANCY: RELATIONS WITH GESTATIONAL DIABETES AND HYPERTENSION, AND BIRTH OUTCOMES

To study the relationship between pre-pregnancy body mass index (BMI) and weight gain during pregnancy with pregnancy and birth outcomes, with a focus on gestational diabetes and hypertension and their role in the association with fetal growth Weight before pregnancy (W1) and weight after delivery (W2) were collected and we calculated BMI and net gestational weight gain, net GWG = (W2 - W1)/(weeks of gestation).Gestational diabetes, hypertension gestational age and birth weight were collected. High BMI was more strongly related to the risk of giving birth to a large-for-gestational-age (LGA) baby than high net GWG (odds ratio OR [95% CI] of 3.23 [1.86–5.60] and 1.61 [0.91–2.85], respectively). Higher net gestational weight gain was significantly associated with an increased risk of LGA only after accounting for blood pressure and glucose disorder High gestational weight gain should not be neglected in regard to risk of LGA in women without apparent risk factors.
