HealthDay News — The amount of US health care resources devoted to treating obesity-related illness in US adults rose 29% from 2001 to 2015, according to a review published in Clinical Chemistry.

Adam Biener, PhD, from the Agency for Healthcare Research and Quality in Rockville, MD, and colleagues analyzed data from the Medical Expenditure Panel Survey (2001 to 2015) to estimate the percentage of health care costs associated with adult obesity, both for the United States as a whole and for the most populous states.

The researchers found that the percent of US national medical expenditures devoted to treating obesity-related illness in adults rose from 6.13% in 2001 to 7.91% in 2015.

“A substantial and rising percentage of health care costs are associated with obesity,” the authors write.
