Weight-related problems, including eating disorders, disordered eating, and obesity, are prevalent among adolescents. School and community-based educators and health care providers have an important role to play in the prevention of weight-related problems in youth. This article includes: 1) a brief overview of weight-related problems in adolescents; 2) a rationale for simultaneously addressing a broad spectrum of weight-related problems, rather than only focusing on eating disorders or obesity prevention; 3) suggestions and program examples for working with adolescents within school and community-based settings; and 4) guidelines for helping parents raise children with healthy eating and exercise behaviors, positive body images, and healthy weights.
