Study of correlation between maternal body mass index with maternal and perinatal outcome

摘要

Background: To study the correlation between maternal body mass index (BMI) with maternal and perinatal outcome in women admitted to labour ward in Department of OBG, VIMS, Ballari. Methods: This observation study was conducted in Department of OBG, VIMS, Ballari for a period of one year between 1st October 2014 to 30th September 2015. All women admitted to labour ward with full term singleton pregnancy were included in the study. The cases were classified into four groups as under-weight (BMI 30kg/m2). The maternal and perinatal outcome noted and studied in the above groups. Results: A total of 500 cases were included during the study period of one year, out of which 15% were under-weight, 68% were normal BMI, 12% were over-weight and 5% cases were obese(BMI 30kg/m2). The patients with low BMI had higher incidence of low birth weight (40%) and perinatal deaths. Increased BMI category was associated with higher incidence of PIH (25-28%), operative deliveries (50-68%), PPH (12%), microsomal babies (32%), low APGAR (24%) and perinatal deaths (12%). Conclusions: Adverse maternal and perinatal outcomes are significantly related to extremes of BMI categories and least complications were seen in normal BMI group.
