Childhood obesity has reached epidemic proportions in the United States, making it a major public health concern. Recent data have suggested an association between adverse childhood experiences and the development of obesity. Children in foster care have high rates of adverse experiences, predisposing this group to higher rates of being overweight (BMI>85%) and obese (BMI >95%). We propose to plan a 12 week healthy lifestyles program for foster children and their caregivers, and to provide a medical home for overweight and obese foster children at the Harbor-UCLA foster care clinic. We plan to integrate medical and nutritional evaluations, nutritional counseling, interactive lecture series, mental health sessions, and grocery shopping and restaurant excursions. We plan to measure outcomes of this program by giving pre- and post-tests assessing nutritional knowledge to the participants and their caregivers. We also plan to measure body mass index (BMI) at regular intervals. This program course will be advertised by the Los Angeles County foster care clinic, local mental health providers, and the Department of Children and Family Services (DCFS).
