The unhealthiest counties in the nation have the highest rates of preventable hospital stays, smoking and adult obesity, according to the 2013 County Health Rankings, a joint effort of the Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute. The healthiest counties, meanwhile, had higher numbers of primary-care doctors.
The least-healthy counties experienced 82.8 preventable hospital stays per 1,000 Medicare enrollees, while in the healthiest counties the rate was 57.2 per 1,000. The rest of the nation's counties experienced 74 preventable hospital stays per 1,000 Medicare enrollees.
The report's authors also found that 24% of adults smoke in the least-healthy counties, compared with 16% in the healthiest and 21% in the other counties.
