Objective: To determine the link between high body mass index (BMI) and poor perinatal outcomes.

Materials and methods: This prospective observational study was conducted in the department of 0bstetrics and Gynaecology , Military hospital, Rawalpindi between 1st January to 31st October 2017. A predesigned questionnaire proforma collected demographic data, obstetric and perinatal outcomes. Chi square and multivariate logistic regression analysis were used for comparison of data.

Results: Of the 395 samples included in the study, 49% had normal BMI, 34% were overweight and 16% were obese. Out of these, 50.5% samples had age between 26-35 years, the mean age(±S.D) was 25.80(±3.5), 92.7% were Punjabi and 73.4% samples were from middle socioeconomic status. High BMI had significant association with GDM, hypertensive disorders of pregnancy, anemia, pulmonary embolism and deep vein thrombosis (DVT), and mode of delivery. There was no statistically significant difference in frequency of PPH, placenta praevia, placental abruption and any other intrapartum complication with BMI. There was a decrease in incidence of induction of labor and instrumental delivery in obese women. A statistically significant increase in incidence of low apgar score at one minute, birth weight >4 kg, need for resuscitation and admission in NICU was associated with obesity.

Conclusion: High BMI has association with poor perinatal outcomes. With good care, obesity may marginally effect perinatal outcome but greatly increases the burden of GDM, hypertensive disorders of pregnancy, anemia, hospital admissions, thromboembolism and NICU admissions.
