The purpose of this study is to examine whether we can use social networks to spread health information and health behaviors that 1) support women in returning to their pre-pregnancy weight after delivery; and 2) promote healthy infant feeding practices.

Detailed Description:

The long-term goal of this research is to prevent obesity-related adverse health outcomes for future generations by applying information emerging from social network studies to the development of new population-based behavioral interventions. There are a number of critical periods during fetal and infant development that appear to influence the later development of obesity. Interventions that prevent insult to these critical windows from occurring could improve children's life course trajectories. This project sets the groundwork for examining whether social networks could explicitly be utilized to prevent obesity from developing by transmitting health information and health behaviors that 1) prevent postpartum weight retention in first time mothers and 2) promote appropriate infant feeding practices. The secondary aim is to assess which individual-level network-related characteristics best predict postpartum body composition and infant feeding practices.
