FAYETTEVILLE, Ark. (KNWA/KFTA/KSNW) — The Lung Institute, a source for pulmonary information for better lung health, including disease prevention and management, commissioned a national study to establish a ranking of lung health across America over a five-year period.

According to its report, Kansans have the seventh-worst lung health in the United States. This data analysis included the change in smoking rate in each state, as well as the change in pollution level over the past five years.

The report shows no change in the percentage of Kansans who smoke. It says 18% of Kansans were smokers in 2016, and the percentage was still the same last year.

Virginia was named as the top state for lung health, with Colorado, Tennessee, Delaware and Washington rounding out the top five. The states with the unhealthiest lungs were Texas, Oklahoma, Oregon, Maine and Missouri.
