Research Involves

Excess pregnancy weight gain (PWG) increases maternal risks for postpartum weight retention and obesity, and is a key risk factor for high infant birth weight and obesity in children. More than half (50-60%) of women exceed the national guidelines for PWG, significantly increasing risks of maternal and infant obesity.

Seeking to develop interventions that promote applicable weight gain, the goal is to improve the physical and mental well-being of women and their children through appropriate PWG. Given the difficulties in treating obesity, resources need to be focused on prevention. By targeting pregnancy, two groups, mothers and their children, will benefit.
