The Health and Obesity: Prevention and Education (HOPE) project is a multidisciplinary, healthy living counseling curriculum to educate pediatric clinicians in training on how to recognize children who are at risk for obesity and its comorbidities and how to promote healthy weight among children and their families. Curriculum topics were selected by experts of nutrition, medicine, dentistry, behavioral counseling, and education and incorporate the recent 2007 Expert Committee recommendations regarding the prevention, assessment, and treatment of childhood and adolescent obesity. The HOPE curriculum instructs medical and dental clinicians on the health consequences of childhood obesity and screening techniques to identify children and families at risk, reviews the current evidence for health intervention recommendations, and teaches trainees regarding the theoretical rationale and art of constructive and culturally sensitive weight counseling for behavioral change. Although designed and tailored specifically for and currently available medical and dental trainees, the HOPE curriculum is Web-based and will also be made available to currently practicing clinicians across the United States beginning in winter 2009. This educational tool, grounded in understanding of relevant sciences, literature, and research methods, provides clinicians with the skills necessary to identify and counsel patients who are at risk to promote healthy weight among youth. This article discusses the approach and methods used for curriculum development. Future publications will discuss HOPE project implementation and outcomes.
