Maternal diet and body composition prior to pregnancy influence gestational weight gain and infant growth patterns. Low maternal pre-pregnancy weight, low BMI, and low attained weight throughout pregnancy are associated with impaired fetal growth, while obesity and high weight gain increases the risks of multiple adverse pregnancy outcomes and excessive fetal growth and offspring obesity. Currently the US Institute of Medicine guidelines for gestational weight gain are the only ones available for developed countries where mean maternal height is similar to that in the US. While these guidelines should be followed, attention should be given to body composition before pregnancy, and measures of body habitus such as maternal height should be taken into account.
