The Baton Rouge metro area ranked No. 96 in the Asthma and Allergy Foundation of America’s annual Top 100 list of most challenging places to live with asthma.

New Orleans ranked No. 47 on the list released Tuesday, World Asthma Day.

The rankings are based on 12 data sets that include estimated asthma prevalence, pollen score, air quality, and medical factors.

The Baton Rouge area ranked better than average in the estimated prevalence of asthma, air quality and bans on smoking in public places. But the metro area was worse than average when it came to poverty, use of quick-relief and asthma-controlling medications.

“Many local community issues like air pollution, poverty or crowded emergency rooms are asthma-related issues that affect one patient at a time, one day at a time, right here in our own cities and towns,” Bill McLin, president and chief executive officer of the Asthma and Allergy Foundation of America, said in a news release. “And people with severe asthma are most at risk.”

More than 300 million people worldwide live with asthma, nearly 25 million of them in the United States.

Memphis, Tenn., was the most challenging place to live for asthma sufferers. Others in the Top 5 were New Haven, Conn.; Knoxville, Tenn.; Pittsburgh; and Chattanooga, Tenn. All had worse-than-average pollen counts, air quality, and lacked bans on public smoking.
