Background: Overweight, obesity, and morbid obesity in the mother are associated with adverse obstetrics well as neonatal outcome. Aim of this study was to assess the prevalence of overweight and obesity, and the impact of body mass index (BMI) on maternal and neonatal outcome.

Methods: This is a retrospective study from January 2018 to September 2018 on 180 women with singleton term pregnancies. Maternal and neonatal outcomes at delivery were noted.

Results: In present study, 3 (1.66%) pregnant women were underweight, 57 (31.66%) pregnant women had normal BMI, 71 (39.44%) pregnant women were overweight while 49 (27.22%) pregnant women were obese. Gestational weight gain was less than 8 kgs in 40 (22.22%) pregnant women, weight gain was 8-15.9 kgs in 132 (73.33%) pregnant women while weight gain was more than 16 kgs in 8 (4.44%) pregnant women. Out of 3 underweight women, 1 delivered by cesarean section and 2 had normal delivery, out of 57 women with normal BMI, 21 delivered by cesarean section and 36 had normal delivery, out of 71 overweight women, 47 delivered by cesarean section and 34 had normal delivery while out of 49 obese women, 38 delivered by cesarean section and 11 had normal delivery. PET and GDM was seen in 9 (7.5%) women each while macrosomia were seen in 5 (4.16%) women.

Conclusions: Increased association was seen with maternal obesity and adverse outcome of pregnancy like PIH, GDM, cesarean section.
