Overhaul needed in US to curb obesity: experts

WASHINGTON--Two-thirds of American adults are too fat, and a major overhaul of U.S. policies — from schools to restaurants to urban planning — is needed to stem the epidemic, medical experts said Tuesday.
In a hefty, 400-plus page report, the Institute of Medicine (IOM) called for urgent action to reverse national obesity trends that are costing the US$190.2 billion a year in illness-related costs.
Peppered with terms like "synergies," "empower" and "systems approach," the report called for a renewed focus on schools as the place where eating habits take hold for life, noting that 17 percent of U.S. children are obese, a figure that has tripled in 30 years.
Offering lunches packed with veggies and whole grains and limiting access to sugar-sweetened drinks were among the recommendations for kids age six to 18.
States and local schools should also make sure all children and teenagers have the opportunity for 60 minutes of exercise per day, said the report titled "Accelerating Progress in Obesity Prevention: Solving the Weight of a Nation."
Other top goals for all ages included making physical activity a daily routine, making healthy food and drink choices widely available, and expanding the role of doctors, insurers and employers.
"Because obesity is such a complex and stubborn problem, a bold, sustained and comprehensive approach is needed," said the report.
"Action must occur at all levels — individual, family, community, and the broader society."
The IOM report reviewed past strategies for obesity prevention in order to come up with new recommendations to speed progress, it said.
"Left unchecked, obesity's effects on health, healthcare costs, and our productivity as a nation could become catastrophic," added the report.
People who belong to ethnic minorities, who have lower incomes and less education are more susceptible to obesity, partly due to policy decisions that result in limited access to healthy foods and places to enjoy exercise.
For instance, one third of children born today — and half of Hispanic and black children — will develop type-2 diabetes in their lifetime, according to projections cited by the IOM.
"Some communities may have no safe place to walk or play, no shops offering affordable healthy food, and widespread advertisements of unhealthy food and beverages," said the report.
Community planners could work harder to make sure there are safe places for exercise, for example by converting an unused railroad bed into a running and biking trail, said the report.
"People only have a certain, limited ability to control their weight in an environment where there is a lot of food available," said IOM committee member Shiriki Kumanyika, professor of epidemiology at the University of Pennsylvania.
"One of the main reasons (for obesity) has to do with people being presented with large quantities of food — tasty food — in a culture where more is better, portion sizes are getting larger and heavily advertised," she told AFP.
