Pre-pregnancy BMI-specific optimal gestational weight gain for women in Japan.

ABSTRACT:

Background

The Institute of Medicine (IOM) guidelines are the most widely used guidelines on gestational weight gain; however, accumulation of evidence that body composition in Asians differs from other races has brought concern regarding whether their direct application is appropriate.
