Results: There were statistically significant difference between the two group in incidence of chronic hypertension (P = 0.02), gestational diabetes (P = 0.05), symptomatic fibroid (P = 0.01), frequent hospitalisation (P = 0.007), caesarean section (P = 0.005), operative vaginal delivery (P = 0.042), Induction of labour (P = 0.024) premature delivery (P = 0.001), low birth weight (P = 0.021) and congenital abnormality but not in Preeclampsia, malpresentation, obstetric haemorrhage, wound infection and multiple pregnancy .
