Researchers analyzed the U.S.-based All of Us database to determine the prevalence of obesity under the new definition.
Of the 301,026 participants aged 18–80 years included in the analysis, 128,992 individuals (42.9 percent) were deemed to be obese under the traditional BMI-based criteria. But under the new definition, 206,361 individuals, or 68.6 percent, were considered obese. Obesity was found to be more prevalent with older age.
“We already thought we had an obesity epidemic, but this is astounding,” said co-first author Lindsay Fourman, according to an Oct. 15 report by The Harvard Gazette, the official news website for Harvard University.
“With potentially 70 percent of the adult population now considered to have excess fat, we need to better understand what treatment approaches to prioritize.”
According to the study, 78,047 participants (25.9 percent) who were not classified as obese under the traditional definition were reclassified as having obesity under the anthropometrics-only criteria. Among these individuals, 22.3 percent had a BMI traditionally classified as underweight or normal, with the remaining in the overweight category.
