Introduction

This knowledge path has been compiled by the Maternal and Child Health Library at Georgetown University. It offers a selection of current, high-quality resources about the prevention, identification, management, and treatment of overweight and obesity in children and adolescents in homes, schools, and communities. Separate sections list resources for families, schools and after-school programs, and child care settings. The final section presents resources about the impact of media use. The knowledge path will be updated periodically.

Please note: In January 2007, the American Medical Association's Working Group on Managing Childhood Obesity released recommendations on the assessment, prevention, and treatment of child and adolescent overweight and obesity. With regard to classification, the group recommends that "(a) individuals from the ages of 2 to 18 years, with a BMI > 95th percentile for age and sex, or BMI exceeding 30 (whichever is smaller), should be considered obese; and (b) individuals with BMI > 85th percentile, but < 95th percentile for age and sex, should be considered overweight, and this term replaces "at risk of overweight." The Centers for Disease Control and Prevention (CDC) uses the term "overweight" to refer to children and adolescents ages 2-19 who have body mass indexes (BMIs) equal to or greater than the 95th percentile for children of the same age and gender (See CDC's Defining childhood overweight (2007)). However, the terms "overweight" and "obesity" are frequently used interchangeably in the literature to describe this group of children and adolescents. Therefore, throughout this knowledge path, both terms are used frequently following the usage of the source being described.
