Outcomes of maternal weight gain.

Abstract

Gestational weight gain is associated with some infant and maternal outcomes. One weight gain recommendation for all women is not supported by the evidence identified in this review. To understand fully the impact of gestational weight gain on short- and long-term outcomes for women and their offspring will require that researchers use consistent definitions of weight gain during pregnancy, better address confounders in their analyses, improve study designs and statistical models, and conduct studies with longer followup.
