To measure the prevalence of antenatal, intrapartum and postpartum complications in the mother and the fetus/newborn in relation to their BMI.
To determine the mean intrapregnancy weight gain for each BMI category.
Methods
A total of 102 women were included in the study. Of these, 29 (28.4%) were underweight, 36 (35.2%) had normal BMI, 14 (13.7%) were overweight, 19 (18.6%) were obese and 3 (2.9%) were morbidly obese.(chart 1 )
A comparison of the sociodemographic characteristic of the women in the five BMI categories is presented in table 1.

This is a cross sectional study conducted between December 2011 and November 2012. The study includes all primigravida who booked before 14 weeks of gestation.
Upon delivery women had their antenatal, intrapartum and postpartum events reviewed and then categorized into five BMI groups; underweight (≤ 19.9 kg/m2), normal (20-24.9kg/m2), overweight (25-29.9kg/m2), obese (30-34.9 kg/m2) and morbidly obese (>35kg/m2). Women were followed up until discharged and reviewed again at 6 weeks postpartum.
All statistical analyses were performed with the use of SPSS for Windows, version 18.0 (SPSS) and P-value of less than 0.05 was taken to be statistically significant

The maternal risk increases as the BMI increases whereas the fetal risk increases with the extreme of BMI (underweight and morbidly obese). Inappropriate weight gain was observed in all groups but was significant in the morbidly obese.

The morbidly obese group was found to experience higher percentage of gestational diabetes mellitus (33%), pregnancy induced hypertension (100%), preterm delivery (33%), augmentation (100%) and instrumentation (33%). Risk of caesarean section was highest (64%) in the overweight group. Highest risk of shoulder dystocia (33%) and wound dehiscence (15.8%) were observed in the obese group.The underweight women had higher risk for preterm delivery (17%).

Values expressed as number ( percent)
The mean intrapregnancy weight gain for each BMI category were:12.2 ± 4.6kg (underweight), 13.6 ± 4.4kg (normal), 12.8 ± 5.5 kg (overweight), 12.4 ± 6.2kg (obese) and 0.8 ± 7.8kg (morbidly obese). Morbidly obese group had lower intrapregnancy weight gain compared to other groups (P = 0.004).
