Perinatal outcomes associated with prepregnancy body mass index and weight gain during pregnancy / 대한산부인과학회지

ABSTRACT

OBJECTIVE: To examine the association between prepregnancy body mass index (BMI), gestational weight gain and perinatal outcomes. METHODS: The data of women who delivered at term in our institute from January 2005 to December 2007 were analyzed retrospectively. Four categories of prepregnancy BMI and three categories of gestational weight gain were constructed and used maternal, neonatal outcomes. RESULTS: This study included 225 women with term delivered in our institute. According to prepregnancy BMI categories, lean ( or =25) were 35, 132, 31, 27, respectively. According to gestational weight gain categories, lean (13.5 kg) were 73, 44, 108, respectively. Gestational weight gain above guidelines was common in low prepregnancy weight group, this difference was statistically significant. In women with increased prepregnancy BMI was associated with increased risk of gestational diabetes mellitus, cesarean section rate, and large for gestational age (LGA) (P<0.05). In women with overweight gain during pregnancy was associated with increased cesarean section rate and LGA (P<0.05). CONCLUSION: Increased prepregnancy BMI was associated with increased gestational diabetes mellitus, cesarean section rate, and LGA. Also excessive weight gain during pregnancy was associated with increased cesarean section rate and LGA.
