BACKGROUND An increasing BMI is associated with an increased incidence of hypothyroidism, gestational diabetes mellitus, gestational hypertension, macrosomia, induction of labour, cesarean deliveries, PPH (Postpartum Haemorrhage), infections, lactation dysfunction, NICU (Neonatal Intensive Care Unit) admissions, neonatal & childhood morbidity. We wanted to compare BMI with mother and child outcomes during pregnancy. METHODS Women attending antenatal OPD for antenatal checkup, at CKM Government Maternity Hospital, Warangal, from January 2018 to June 2019 were included after informed and written consent. The above women were grouped into standard BMI groups and their obstetric outcomes and perinatal outcome variables were evaluated. RESULTS Increased rate of hypothyroidism, GDM, GHTN and anaemias was associated with high BMI group when compared to normal group (p = 0.001, significant). Increased rate of LSCS was noted in the high BMI group 41.67 % (n = 60) when compared to normal 16.5 % (n = 18) (p = 0.001, significant). Increased rate of instrumental deliveries was seen in the high BMI group 10 % (n = 15) when compared to normal BMI group 2.8 % (n = 3) (p = 0.001, significant). Increased rate of PPH was associated with both low and high BMI 2.1 % (n = 1) and 6.9 % (n = 10) respectively when compared to normal BMI 0 %, with p = 0.001 (significant). Increased rate of wound complications was associated with high BMI group 9.7 % (n = 14) when compared to normal BMI group 0.9 % (n = 1), p = 0.001 (significant). Increased rate of lactation dysfunction was associated with high BMI group 10 % (n = 15) when compared to normal BMI group, p = 0.001 (significant). Increased rate of NICU admissions was associated with underweight group 17 % (n = 8) & high BMI 43.3 % (n = 13) when compared to normal 2.8 % (n = 3) p = 0.001 (significant). CONCLUSIONS Body Mass Index has significant association with anaemia, low birth weight, small for gestational age, and neonatal intensive care unit admissions.
