This study attempts to determine the association of gestational weight gain and the effect on pregnancy outcome defined by their Body Mass Index (BMI) among pregnant women. Retrospective study involved 436 singleton pregnancy women who delivered in Hospital Kuala Lumpur (HKL) from 1st January to 31st December 2010. The subjects were stratified into four BMI group according to World Health Organization (WHO) (underweight <18.5 kg m-2, normal: 18.5-24.9 kg m-2, overweight: 25-30 kg m-2 and obese: 30 kg m-2). Each of BMI group then, classified into 3 categories of Gestational Weight Gain (GWG) (lower increment, normal and high increment). This classifying of GWG group was done according to the US Institute of Medicine (IOM), 2009 guidelines. Pregnancy outcome been analyzed according to the GWG during pregnancy for each BMI group and calculated the crude OR from simple logistic regression modules. 15.1, 40.1, 28.7 and 16.1% of the subjects were underweight, normal BMI, overweight and obese, respectively. In normal BMI women, gestational age outcome and neonatal outcome were significantly associated with inadequate weight gain during pregnancy (p = 0.046 and p = 0.002). Among low GWG of normal BMI women, the crude OR for premature birth and low birth weight were 2.872 and 4.976 (95% CI = 1.009-8.170 and 1.316-18.815), respectively compared with normal GWG. This study shows that normal BMI with lower GWG may result in adverse outcome. In addition, inadequate weight gain during pregnancy can result in significant complication.
