The pediatric office has an important role in national efforts to reverse rising trends in the prevalence of childhood overweight. Overweight may be established at a young age and is difficult to reverse. Lifestyle choices associated with overweight are common and their development may begin in very young children. Therefore, there is a necessity to apply a preventive strategy that addresses all children to promote healthy lifestyle choices from birth onward and to develop an intervention strategy that works by changing family habits so that healthy lifestyle habits are reinforced. It is crucial to develop, evaluate, and apply new systems and practical approaches to aid in this effort in the pediatric practice setting.
