11 Assuming that the same trends continue, by 2015 2 in every 5 adults and 1 in every 4 children in the United States will be obese. Among American children 6 to 11 years of age, an estimated 4.2 million (2.3 million boys and 1.9 million girls) are overweight among American adolescents 12 to 19 years of age, 5.7 million (3.1 million boys and 2.6 million girls) are overweight. 6–10 Based on data from the 2003–2004 US National Health and Nutrition Examination Survey (NHANES), approximately 66 million American adults (30 million men and 36 million women) are obese and an additional 74 million (42 million men and 32 million women) are overweight. The obesity epidemic is a major concern for the health of populations in the United States and many other nations. Source: National Center for Health Statistics. The evidence-based experience for population-wide approaches to obesity prevention is highlighted.įigure 2. This American Heart Association scientific statement aims: 1) to raise awareness of the importance of undertaking population-based initiatives specifically geared to the prevention of excess weight gain in adults and children 2) to describe considerations for undertaking obesity prevention overall and in key risk subgroups 3) to differentiate environmental and policy approaches to obesity prevention from those used in clinical prevention and obesity treatment 4) to identify potential targets of environmental and policy change using an ecological model that includes multiple layers of influences on eating and physical activity across multiple societal sectors and 5) to highlight the spectrum of potentially relevant interventions and the nature of evidence needed to inform population-based approaches. Population-based approaches to obesity prevention are complementary to clinical preventive strategies and also to treatment programs for those who are already obese. To prevent the development of overweight and obesity throughout the life course, population-based strategies that improve social and physical environmental contexts for healthful eating and physical activity are essential. The importance of effective interventions to reduce obesity and related health risks has increased in recent decades because the number of adults and children who are obese has reached epidemic proportions. Obesity is a major influence on the development and course of cardiovascular diseases and affects physical and social functioning and quality of life.
