Fewer than one-third of Americans are currently at a healthy weight, with the rest of the population either overweight or obese, a new report finds.
About 35% of men and 37% of women are obese. Another 40% of men and 30% of women are overweight, researchers said in the June 22 issue of JAMA Internal Medicine.
“Obesity is not getting better. It’s getting worse, and it’s really scary. It’s not looking pretty,” said Lin Yang, a postdoctoral research associate at Washington University School of Medicine in St. Louis.
Obesity has been linked to a number of chronic health conditions, including type 2 diabetes, heart disease, certain cancers, and arthritis, Yang said.
“This generation of Americans is the first that will have a shorter life expectancy than the previous generation, and obesity is one of the biggest contributors to this shortened life expectancy because it is driving a lot of chronic health conditions,” she said.
The new report used data from the National Health and Nutritional Examination Survey gathered between 2007 and 2012, involving more than 15,000 men and women age 25 and older.
Based on the data, researchers estimate than more than 36 million men and nearly 29 million women in the United States are currently overweight. About 32 million men and 36 million women are obese, the researchers found.
Overweight is defined as having a body mass index (BMI) between 25 and 29.9, according to the U.S. Centers for Disease Control and Prevention. BMI is calculated by comparing a person’s weight to their height.
Obesity is defined by the CDC as any body mass index 30 or higher. A 5’9” man who weighs 203 pounds or more is considered obese, as is a 5’4” women who weighs 175 pounds or more.
The new obesity figures did not come as a surprise to Dr. Elliott Antman, president of the American Heart Association.
“It’s in line with what we already knew, and it provides some numbers on the magnitude of the problem,” Antman said of the study. “It puts a face on the issue, and it’s a significant problem.”
American’s weight problem is an issue that will not be resolved through a purely medical solution, Yang and Antman said. Politicians and officials at the federal, state and local levels will need to weigh in with policies that increase the number of calories people burn and decrease the amount of unhealthy foods they ingest.
For example, communities need to adopt plans that will make it easier for people to get around on foot or riding a bike, rather than sitting in a car, Yang said.
“American is a very much car-dependent country. We know car driving is a chunk of sedentary behavior,” she said. “More walking or bicycling would increase the physical activity of the whole nation.”
Policymakers also need to find ways to improve the availability of inexpensive, healthy food, Antman said. Right now, processed food and fast food that is high in unhealthy sugar, salt and fat tends to be more affordable and available in America’s communities than healthier options.
“Fast foods are less expensive, so that individuals trying to feed a large family might tend to purchase them rather than fresh foods, which are harder to find and more expensive, and therefore less economically appealing,” he said.
I seldom see researchers take such a strong political stand on vital health care issues and I applaud their efforts. We are each individually responsible for our own health. However, we are all responsible as a nation to support policy that improves general health rather than just drive up the cost of health care. It never ceases to amaze me that a politician cannot or will not see the health care cost savings of converting an abandoned railroad track to a bicycle trail.
Take responsibility for your general health and push your elected officials to support policies that will improve the health of our nation.
