Abstract
|
|
|
Objective: To evaluate the association between gestational maternal weight gain during each trimester and neonatal birth weight.
Methods: A retrospective cohort study was conducted. Data were obtained from medical records of women who received her first antenatal care before 10 weeks’ of gestation and delivered term singleton neonates at Cheil General Hospital. Correlation between rate of maternal weight gain at each trimester (kg/wk) and neonatal birth weight was analyzed according to parity after adjustment for maternal age, pre-pregnancy body mass index, total weight gain, and gestational age at delivery.
Results: A total of 2,105 pregnant women were included. Of them, 1,266 women were nullipara and 839 women were multipara. In correlation analysis, maternal weight gain at the second trimester was more associated with neonatal birth weight than those of other trimesters, regardless of parity.
Conclusion: We suggest that obstetricians should be more concerned about maternal weight gain at the second trimester for appropriate neonatal birth weight.
