After three decades of increases, adult obesity rates remained level in every state except for one, Arkansas, in the past year, according to F as in Fat: How Obesity Threatens America's Future 2013, a report from the Trust for America's Health (TFAH) and the Robert Wood Johnson Foundation (RWJF). The full report is available here. Visit http://www.FasinFat.org/ for interactives, graphs, charts and obesity rates for the states and nation going back decades.
Thirteen states now have adult obesity rates above 30 percent, 41 states have rates of at least 25 percent, and every state is above 20 percent, according to the report. In 1980, no state was above 15 percent; in 1991, no state was above 20 percent; in 2000, no state was above 25 percent; in 2007, only Mississippi was above 30 percent.*
Since 2005, there has been some evidence that the rate of increase has been slowing. In 2005, every state but one experienced an increase in obesity rates; in 2008, rates increased in 37 states; in 2010, rates increased in 28 states; and in 2011, rates increased in 16 states.*
