ObjectiveTo determine the effect of maternal pre-pregnancy BMI on pregnancy outcomes.MethodsPregnancy cohort recruited pregnancies between 16 and 18 weeks. BMI evaluated underweight, BMI <18.5, normal, BMI 18.5–25, overweight BMI 25–30, and obese BMI > 30 women.ResultsPre-pregnancy BMI classified 331 women as underweight (11.7%), 1982 normal (69.9%), 326 overweight (11.5%), and 188 as obese (6.6%). Obese women were more likely to develop gestational diabetes (p <0.001), hypertension (p <0.001), preeclampsia (p <0.001), need labor induction (p <0.001), cesarean delivery for fetal distress (p <0.001), postpartum hemorrhage (p = 0.003), need neonatal resuscitation (p = 0.001) and deliver hypoglycemic infants (p = 0.007). Being underweight is correlated with fetal growth restriction (p = 0.001).ConclusionPre-pregnancy obesity is a risk factor for gestational diabetes, preeclampsia, labor induction, cesarean for fetal distress, postpartum hemorrhage and neonatal hypoglycemic and need for resuscitation. Being underweight is risk factor for fetal growth restriction.
