Mounting evidence documents the extraordinary toll on human health resulting from the consumption of unhealthy food products and physical inactivity. Diseases related to poor nutrition – such as diabetes, heart disease, stroke, and some cancers – are among the leading causes of disability and death in the United States. Poor diet and lack of exercise come second only to tobacco use in actual causes of preventable death in this country. It is estimated that 6% of all adult health care, 7% (...) of Medicare, and 11% of Medicaid expenditures are attributable to obesity. According to the Centers for Disease Control and Prevention, the direct medical cost associated with physical inactivity was nearly $76.6 billion in 2000.In response to America's growing obesity problem, local policymakers have been looking for legal strategies to adopt in their communities to encourage healthful behaviors. Taking the lead from the successful tobacco control movement, nutrition advocates are seeking strategies to “denormalize” unhealthy behaviors, rather than pursuing education-based approaches that encourage individuals to change their own personal behavior.

Defining “community” from a research perspective is difficult. Communities consist of environmental, social, and geographic components. In addition, race, ethnicity, socio-economic status, and group memberships often play roles in community identity. Barry Wellman and Scot Wortley urge that to truly understand and influence a community, and most certainly to conduct research within communities, one must take into account the varied nature of relationships and networks and how they may work together synergistically to meet the needs of community members. Using the (...) Social Ecological Model, with its delineation of multiple spheres of influence, community-based research has attempted to reach this understanding. Although dramatic shifts have not yet been realized, many studies suggest improved health behaviors and healthy environments, which indicate a promising future for community intervention work. The discussion that follows reviews the theory and rationale for community-based interventions, the socialecological approach to understanding and studying obesity, and the progress and promise of community interventions.

Childhood obesity continues to rise in the United States, with now over 17% of children and adolescents considered overweight. Childhood obesity predisposes an entire generation to increased risk of chronic diseases and disabilities and is a severe threat to the economic well-being of the nation. At first thought, the solution to the obesity epidemic may seem simple: encourage people to eat less and exercise more. However, the reality is that behavioral change is difficult to achieve without also considering the interplay (...) of genetics, biological processes, and social and environmental mechanisms. As such, investment in obesity research has been considered an important tool to combat obesity and obesity-related diseases. Childhood obesity research, in particular, has drawn considerable attention, given the lower cost of prevention relative to treatment and the high potential for long-term benefits at a population level.

Childhood obesity is a serious problem for increasing numbers of children around the world. According to the International Obesity Task Force, 1 of 10 schoolaged children worldwide is overweight or obese, a number totaling 155 million; of these, 2-3% are obese. Prevalence is highest in the Americas and Europe, followed by the Near/Middle East, with smaller but growing numbers in the Asia-Pacific and Sub-Saharan regions of the world.In the United States, which provides the data for much of this report, prevalence (...) continues to rise. The most recent nationally representative data indicate that 33.6% of individuals aged 2-19 years were overweight and 17.1% were at risk for overweight in 2003-2004, compared to 28.2% and 13.9% in 1999-2000, respectively. In this age group, the prevalence of overweight or at risk for overweight was highest among Mexican Americans, followed by Non-Hispanic blacks and Non-Hispanic whites, and a higher percentage of males were overweight compared to females.

The obesity epidemic among children and adolescents in the United States continues to worsen. The most recent analysis of data from the National Health and Nutrition Examination Survey showed that the prevalence of overweight among children and adolescents – defined as a Body Mass Index at or above the 95th percentile on gender-specific BMI-for-age growth charts developed by the Centers for Disease Control and Prevention – increased significantly between 1999-2000 and 2003-2004. Over this period, the prevalence of overweight among children (...) and adolescents aged 2-19 increased 23% – from 13.9% to 17.1%. In 2003-2004, 18.8% of children aged 6-11 and 17.4% of adolescents aged 12-19 were overweight. Roughly comparable proportions of each age group were considered to be at risk of becoming overweight.

Eating behaviors evolve during the first years of life as biological and behavioral processes directed towards meeting requirements for health and growth. For the vast majority of human history, food scarcity has constituted a major threat to survival, and human eating behavior and child feeding practices have evolved in response to this threat. Because infants are born into a wide variety of cultures and cuisines, they come equipped as young omnivores with a set of behavioral predispositions that allow them to (...) learn to accept the foods made available to them. During historical conditions of scarcity, family life and resources were devoted to the procurement and preparation of foods, which are often low in energy, nutrients, and palatability. In sharp contrast, today in non-Third World countries children's eating habits develop under unprecedented conditions of dietary abundance, where palatable, inexpensive, ready-to-eat foods are readily available.

After years of near total neglect, the problem of childhood obesity is now in the limelight. Terms like “epidemic,” “crisis,” and “emergency” are used frequently when describing the trend. Progress is defined with strong language and fueled by statistics such as the observation that this generation of children will be the first to live shorter lives than their parents. Multi-disciplinary journals such as the Journal of Law, Medicine & Ethics have dedicated symposiums to the issue, and conferences have been convened (...) not only by health professionals but by government agencies, the food industry, and even professionals who market to children. The seriousness of childhood obesity is no longer in doubt, and finally attention has turned to the more complex question – what must be done? (shrink)

It is now well recognized that the United States is a consumer-driven society. Private consumption comprises a rising fraction of GDP, advertising is proliferating, and consumerism, as an ideology and set of values, is widespread. Not surprisingly, those developments are not confined to adults; they also characterize what some have called “the commercialization of childhood.” Children are more involved than ever in media, celebrity, shopping, brand names, and other consumer practices. At the core of this change is children's growing role (...) as independent consumers. In recent years, children's access to income has risen markedly, and they have gone from being purchasers of cheap plastic goods and a few select food items to being a major market for a diverse set of goods and services, including foodstuffs. Unofficial estimates suggest that children aged four to twelve spent a reported $6.1 billion in purchases from their own money in 1989, $23.4 billion in 1997, and $30 billion in 2002, for a total increase of four hundred percent.

Childhood obesity is in important respects a result of legal policies that influence both dietary intake and physical activity. The law must shift focus away from individual risk factors alone and seek instead to promote situational and environmental influences that create an atmosphere conducive to health. To attain this goal, advocates should embrace a population-wide model of public health, and policymakers must critically examine the fashionable rhetoric of consumer choice.

Mounting evidence documents the extraordinary toll on human health resulting from the consumption of unhealthy food products and physical inactivity. In response to America's growing obesity problem, local policymakers have been looking for legal strategies that can be adopted in their communities to encourage healthful behaviors. In order to provide practical tools to policymakers, this article examines four possible venues for local policy change to improve the health of a community: the school environment the built environment () community facilities and (...) the point of sale environment. Finally, the article examines the use of taxes or fees as a means of paying for nutrition policy work as well as potentially reducing the consumption of unhealthy products. This article illustrates that local laws and policies can be a valuable tool in changing a community's environment in order to improve nutritional options and increase opportunities for physical activity.

Childhood obesity has become a public health epidemic, and currently a battle exists over how to frame and address this problem. This paper explores how public policy approaches can be employed to address obesity. We present the argument that obesity should be viewed as the consequence of a “toxic environment” rather than the result of the population failing to take enough “personal responsibility.” In order to make progress in decreasing the prevalence of obesity, we must shift our view of obesity (...) away from the medical model to a public health model . At the same time, we must be sensitive to the problem of weight bias.Potential obstacles to taking a public policy approach are identified, as well as suggestions on how to overcome them. (shrink)

Childhood obesity is an increasing health threat. The National Institutes of Health is the primary funding agency for research into the causes, mechanisms, consequences, and prevention and treatment of childhood obesity. Using the NIH Strategic Plan for Obesity Research as the framework, this article summarizes the research that has been funded in the past five years as well as new research areas with great potential.

The purpose of this article is to comprehensively review studies that have examined the relation between diet and childhood obesity. The review specifically considers the roles of total energy intake and energy density; dietary composition; individual foods, food groups, and dietary patterns; beverage consumption; and eating behaviors. The paper also discusses methodological considerations and future research directions and concludes by summarizing the evidence presented and highlighting the ethical issues surrounding providing dietary advice.

The first years of life mark a time of rapid development and dietary change, as children transition from an exclusive milk diet to a modified adult diet. During these early years, children's learning about food and eating plays a central role in shaping subsequent food choices, diet quality, and weight status. Parents play a powerful role in children's eating behavior, providing both genes and environment for children. For example, they influence children's developing preferences and eating behaviors by making some foods (...) available rather than others, and by acting as models of eating behavior. In addition, parents use feeding practices, which have evolved over thousands of years, to promote patterns of food intake necessary for children's growth and health. However in current eating environments, characterized by too much inexpensive palatable, energy dense food, these traditional feeding practices can promote overeating and weight gain. To meet the challenge of promoting healthy weight in children in the current eating environment, parents need guidance regarding alternatives to traditional feeding practices. (shrink)

Community-based interventions built on theory and informed by community members produce potent, sustainable change. This intervention model mobilizes inherent community assets and pinpoints specific needs. Advancing community-based research to address obesity will require training of future leaders in this methodology, funding to conduct rigorous trials, and scientific acceptance of this model.

Schools are ideal settings for implementing multi-component programs to prevent and control childhood obesity. Thoughtful improvements to proven strategies, coupled with careful evaluation, can contribute to accumulation of evidence needed to design and implement the next generation of optimal interventions.

Children's exposure to food marketing has exploded in recent years, along with rates of obesity and overweight. Children of color and low-income children are disproportionately at risk for both marketing exposure and becoming overweight.Comprehensive reviews of the literature show that advertising is effective in changing children's food preferences and diets.This paper surveys the scope and scale of current marketing practices, and focuses on the growing use of symbolic appeals that are central in food brands to themes such as finding an (...) identity and feeling powerful and in control.These themes are so potent because they are central to children in their development and constitution of self. The paper concludes that reduction of exposure to marketing will be a central part of any successfu anti-obesity strategy. (shrink)
