With an obesity rate of 28.5 percent, Pennsylvania is the 19th most obese state in the country.

According to the eighth annual "F as in Fat" report by the Trust for America's Health and the Robert Wood Johnson Foundation, adult obesity ratesincreased in the Keystone State and 15 others last year.

Pennsylvania had an adult obesity rate of 28.1 percent in 2009, when the Trust for Public Health conducted its last survey. The state had an obesity rate of 16.2 percent in 1995.

No state saw a reduction in obesity rates in the past year, despite new federal and state interventions designed to promote physical activity and increase access to healthy food.

Still, there was a bright spot in the data: The number of states showing increased obesity rates dropped to 16 this year from 28 in 2010.

Dr. Jim Marks, senior vice president of the Robert Wood Johnson Foundation, cautioned, however, that governments still have a long way to go because no state has yet shown a decrease in obesity.

"We want to see the epidemic stop and [obesity rates] turn down," he said.

Diabetes rates in Pennsylvania reached 9.4 percent last year. Fifteen years ago, that rate was 5.8 percent. Hypertension has also grown more prevalent: 28.9 percent of the population now suffers from high blood pressure compared to 23.7 percent in 1995.
