Our nation stands at a crossroads. Today's epidemic of overweight and obesity threatens the historic progress we have made in increasing American's quality and years of healthy life. Two-third of adults and nearly one in three children are overweight or obese. In addition, many racial and ethnic groups and geographic regions of the United States are disproportionately affected. The sobering impact of these numbers is reflected in the nation's concurrent epidemics of diabetes, heart disease, and other chronic diseases. If we do not reverse these trends, researchers warn that many of our children-our most precious resource-will be seriously afflicted in early adulthood with medical conditions such as diabetes and heart disease. This future is unacceptable. The Surgeon General asks you to join me in combating this crisis. Every one of us has an important role to play in the prevention and control of obesity. Mothers, fathers, teachers, business executives, child care professionals, clinicians, politicians, and government and community leaders-we must all commit to changes that promote the health and wellness of our families and communities. As a nation, we must create neighborhood communities that are focused on healthy nutrition and regular physical activity, where the healthiest choices are accessible for all citizens. Children should be having fun and playing in environments that provide parks, recreational facilities, community centers, and walking and bike paths. Healthy foods should be affordable and accessible. Increased consumer knowledge and awareness about healthy nutrition and physical activity will foster a growing demand for healthy food products and exercise options, dramatically influencing marketing trends. Hospitals, work sites, and communities should make it easy for mothers to initiate and sustain breastfeeding as this practice has been shown to prevent childhood obesity. Working together, we will create an environment that promotes and facilitates healthy choices for all Americans. And we will live longer and healthier lives. In the 2001 Surgeon General's Call to Action to Prevent and Decrease Overweight and Obesity, former Surgeon General David Satcher, MD, PhD, warned us of the negative effects of the increasing weight of our citizens and outlined a public health response to reverse the trend. Although we have made some strides since 2001, the prevalence of obesity, obesity-related diseases, and premature death remains too high. The Surgeon General is calling on all Americans to join in a national grassroots effort to reverse this trend. Plans include showing people how to choose nutritious food, add more physical activity to their daily lives, and manage the stress that so often derails their best efforts at developing healthy habits. The real goal is not just a number on a scale, but optimal health for all Americans at every stage of life. To achieve this goal, we must all work together to share resources, educate our citizens, and partner with business and government leaders to find creative solutions in our neighborhoods, towns, and cities from coast to coast. Together, we can become a nation committed to become healthy and fit.
