Özet

OBJECTIVE: To investigate the effects of pre-pregnancy body mass index and weight gain during pregnancy on perinatal outcomes and delivery mode. \rSTUDY DESIGN: In this retrospective cohort study, 722 pregnant women giving birth between 2018-2019 \rwere screened from our hospital database. First, they were divided into four groups according to their prepregnancy body mass index (low-weight/normal-weight/overweight/obese), and then they were redivided \rinto three groups according to pregnancy weight gain (?7/8-15/?16 kg). Prenatal body mass index and \rpregnancy weight gain were compared concerning maternal-neonatal results and mode of delivery. \rRESULTS: According to pre-pregnancy body mass index, among the obese pregnant group, gestational \rdiabetes mellitus (p<0.001), preeclampsia (p=0.029), preterm delivery (p=0.011) and cesarean delivery \r(p=0.061) rates were more common. As the body mass index increases, neonatal intensive care requirement (p=0.0020) and low 1st minute APGAR scores (p=0.019) were detected more frequently. However, \ras pregnancy weight gain decreased, preterm delivery (p=0.041) increased. Also, birth weight increased \r(p<0.001) with the weight gain of the pregnant. Pregnant women gaining more than 16 kg were associated \reither with a lower <2500 g or a higher birth weight risk >4000 g. \rCONCLUSION: Pre-pregnancy high body mass index is associated with negative obstetric outcomes like \rgestational diabetes, preeclampsia, preterm delivery, and increased cesarean rates, and poor fetal incidences with a low APGAR score and high neonatal intensive care admission rates.
