Abstract

Background: Obesity causes major changes in maternal intermediary metabolism & these women are more prone to preeclampsia, gestational diabetes, operative vaginal Deliveries & caesarean deliveries. Present study was aimed to analyse independent association between abnormal BMI and obstetric co-morbidities at a tertiary hospital. Material and Methods: Present study was single-center, prospective, observational study, conducted in pregnant women with singleton pregnancies attending antenatal clinic at our hospital in first trimester, planning to deliver at the same hospital. Pregnant women were placed in standard BMI categories and the obstetric outcome variables were evaluated. Results: During the study period 200 patients were observed. Out of them 85(42.5%) fall in normal Body mass index (BMI), 33(16.5%) fall in underweight category, 63(31.5%) fall in overweight category & 19(9.5%) fall in obese group. Majority of the LSCS (57.9%) were from obese group. Majority of vaginal deliveries (90.9%) were from underweight group. (P≤ 0.001, highly significant). The incidence of GDM was highest in obese group (42.1%) (P≤ 0.001, highly significant) Preeclampsia rate was highest in obese group (26.3%) followed by overweight group (15.87%) (P=0.078). Increased rate of LSCS (41.5%) was associated with high BMI group when compared with normal group (22.4 %) & in underweight group (9.1%) (P=0.001, highly significant). Majority of vaginal deliveries (90.9%) were from underweight group. Rate of preeclampsia was increased in high BMI group (18.3 %) when compared with normal group (7 %) & underweight group (9 %) (P=0.071). Rate of GDM was significantly raised in high BMI group (14.6%) compared to normal (3.52%) & underweight group (3%) (P=0.015). The highest number of postpartum infection 7.3% were from High BMI group when compared with 2.4% from normal BMI group. (P=0.277). Conclusion: Obesity is associated with increased incidence of caesarean delivery, Gestational diabetes, preeclampsia, postpartum infection, and induction of labour.
