Behavioral: Home visit
Three home visits during pregnancy focused on providing education on infant injury prevention

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 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 support women in gaining weight during pregnancy within their clinically recommended weight gain target.
