Title: Addressing Health Literacy and Numeracy to Prevent Childhood Obesity
Brief Summary: In 2003, Surgeon General Richard Carmona suggested that low health literacy is "one of the largest contributors to our nation's epidemic of overweight and obesity." Over 26% of preschool children are now overweight or obese, and children who are overweight by age 24 months are five times as likely as non-overweight children to become overweight adolescents. The aim of the study is to assess the efficacy of a low-literacy/numeracy-oriented intervention aimed at teaching pediatric resident physicians to promote healthy family lifestyles and prevent overweight among young children (age 0-2) and their families in under-resourced communities.
