Women with pre-pregnancy BMI of less than 18.5, compared to normal BMI (BMI 18.5-24.9), had a lower carbohydrate inadequacy in our study, contrasting a finding of a study in China [4].This might be explained by a difference in definition of inadequacy between two studies. However, the link between lower carbohydrate inadequacy and low pre-pregnancy BMI could not be explained. Although a study suggested that the type of carbohydrate may be related to body weight, the daily total carbohydrate intake was not found to be related to BMI [20]
