Oklahoma's getting less healthy, plunging two spots to No. 48 in America's Health Rankings for 2011.

More children in poverty, along with diabetes patients and obese people, helped sink Oklahoma's ranking. Even the significant drop in smoking (to 23.7 percent from 25.1 percent of adults) and a decline in preventable hospitalizations couldn't boost Oklahoma's rankings.

“It's daunting and discouraging that we keep bumping along. We've met the enemy, and we is it,” said Dr. Keith Wilson, marketing medical director for UnitedHealthcare for Oklahoma.

America's Health Rankings is an annual report published by United Health Foundation, American Public Health Association and Partnership for Prevention. Louisiana was 49th in the rankings, and Mississippi was 50th.
