| Summary: | 碩士 === 臺北醫學大學 === 保健營養學研究所 === 98 === The effect of maternal weight gain on obstetric performance is less clear and population based studies in Taiwan reporting on the effect of extremes of body mass index (BMI) on pregnancy outcomes are relatively few. Therefore, we designed this retrospective study to identify risk factors for excessive or inadequate gestational weight gain and prepregnant BMI with associated morbidities among women in a medical center. Data were extracted from the delivery room information bank on all women delivering singleton babies in the Taipei Mackay Memorial Hospital between April to June, 2007. The collected variables including basic information, parity, prepregnant height and body weight, gestational weight gain, gestational complications, the delivery method and neonatal birthweight etc. The women were categorized into 3 groups according to their prepregant BMI and divided to 4 groups depend on the gestational weight gain. The findings showed that prepregant BMI ?d 24kg/m2 increased the risks of gestational diabetes mellitus and macrosomia. Gestational weight gain < 10 kg increased the risks of low baby birthweight and preterm delivery. On the other hand, gestational weight gain ?d 14 kg may increase the risk of higher baby birthweight ; weight gain ?d 18 kg increase the risks of macrosomia and preeclampsia.
