In a New York Post Opinion piece the following claim was made:
An obese adult uses 42 percent more health care than a healthy-weight adult, and a morbidly obese adult uses a staggering 81 percent more, according to the Robert Wood Johnson Foundation.
I tried to find this stat on the Robert Wood Johnson Foundation website, but could not, and it wasn't linked in the NYP article.
I can't say I'm exactly sure of the claim meaning, as "health care" can be measured in time and number of services, as well as dollars, but dollars seems to be the focus. Additionally, the timeframe nor frequency are specified, as this unanswered skeptics question illustrates that lifetime costs and yearly costs could yield different impressions and cost-mitigation decisions.
The idea that obesity is responsible for more health care usage is not new, and considering the long list of correlated illnesses, it makes sense. However, I've never seen such exact numbers claimed, so that is what I want to verify. Do obese adults use 42% more health care and morbidly obese adults use 81% more health care?
