Adults in nearly every state saw their access to health services worsen during over the past decade, with Tennessee, Florida and Georgia having the greatest increase in people reporting having an unmet medical need, according to a study released Tuesday.

The three states had at least a 9 percent jump in the proportion of adults under 65 who said they had unmet medical needs due to cost, according to the report released by the Robert Wood Johnson Foundation, which was conducted by researchers at the Urban Institute.

Urban Institute researchers also conducted a similar study that was published Monday in Health Affairs that showed tens of millions of adults had reduced access to health care over the decade. States with the largest percentage of residents with unmet needs because of cost in 2010 were Mississippi (26 percent), Texas (25.3 percent) and Florida (25.1 percent). States with the lowest were North Dakota (8.2 percent), Massachusetts (8.7 percent) and Hawaii (9.7 percent).
