If people keep gaining weight at the current rate, fat will be the norm by 2020, with 75 percent of U.S. adults overweight and 41 percent obese, U.S. researchers predicted.
A team at Johns Hopkins University in Baltimore examined 20 studies published in journals and looked at national surveys of weight and behavior for their analysis, published in the journal Epidemiologic Reviews.
“Obesity is a public health crisis. If the rate of obesity and overweight continues at this pace, by 2020, 75 percent of adults and nearly 24 percent of U.S. children and adolescents will be overweight or obese,” Dr. Youfa Wang, who led the study, said in a statement.
They defined adult overweight and obesity using a standard medical definition called body mass index. People with a BMI of 25 or above are considered overweight, while those with BMIs of 30 or above are obese and at serious risk of heart disease, diabetes and some cancers.
