Concerning postpartum BMI in our st

Concerning postpartum BMI in our study, we found that 19.5% (36/185) and 0.5% (1/185) of our subjects became overweight and obesity, respectively. Appropriate nutritional recommendation during postpartum period and even during pregnancy should be realized by the obstetricians for the maternal and fetal welfare. The underweight group was 1% (2/185) and was also the problem, for example, during breastfeeding. There were some limitations in our study. Firstly, maternal pre-pregnancy weights and gestational weight gain came from self-recalling which may cause some error of the date. However, this is the best way to get information from all subjects who did not have any previous hospital records.
