WFIR Health NewsRICHMOND, Va. (AP) _ A new report ranks Arlington County as Virginia’s healthiest while Tazewell County is considered the least healthiest. The sixth annual County Health Rankings is based on 30 factors, including education, housing, diet, exercise and jobs. Albemarle County is ranked as the second healthiest county, followed by Fairfax, Loudoun, and York. Henry, Buchanan, Dickenson and Wise are among the least healthy counties. Counties ranked low have more teen births, more smokers and more alcohol-related traffic deaths. The report says the healthiest counties have better access to recreational opportunities, higher college attendance and fewer preventable hospital stays. The Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute released the report on Wednesday.
