Abstract

OBJECTIVE
To establish the biweekly standard values of pregnancy weight gains for primiparas and multiparas, and to investigate the influence of prepregnancy body mass index on biweekly weight gain during pregnancy.
METHODS
We analyzed the biweekly weight gain data from 536 primiparas and 114 multiparas who had noncomplicated singleton term pregnancy. Data was categorized according to parity and body mass index (BMI).
RESULTS
Biweekly weight gain was significantly different among prepregnancy BMI groups from the 15th week but was not different between primiparas and multiparas.
CONCLUSION
To prevent a lot of complications which may be associated with abnormal weight gain during pregnancy, more careful prenatal care according to the prepregnancy BMI groups is needed. To establish the Korean standard value for antenatal weight gain, a nationwide multicenter study is needed.
