title: Effect of body mass index on outcome of labour induction.
abstract: The retrospective study to explore the adverse effect of obesity on pregnancy and labour was conducted at Aga Khan University Hospital, Karachi, Pakistan, and comprised data of all patients booked between 12-14 weeks and required induction of labour from January 1 to December 31, 2012. Women were grouped into two body mass index categories: normal weight (<22.9 kg/ m2) as controls and exposed group (>23 kg/m2). Obesity increased the risk of development of gestational hypertension and diabetes. Therefore obese women were more likely to be induced due to medical indication whether primiparous or multiparous adjusted odds ratio =2.89(95% confidence interval 1.29-6.48) and 2.77 (95% confidence interval 1.07-7.19) respectively. There was increased chance of having caesarean section in primigravida adjusted odds ratio = 1.45 (95% confidence interval 0.72-2.92), duration of caesarean section and blood loss during the procedure were not significantly associated with high body mass index (p>0.05). Obesity may lead to a lot of problems in primigravida, but it did not have major impact.
