Asthma Hits the Obese Harder

Obesity seems to make everything worse. Here’s what I mean. New research claims that serious asthma is more likely to develop in obese individuals than the non-obese. Robert Preidt of HealthDay News reports:
In their study, a team at Emory Crawford Long Hospital in Atlanta examined data from the U.S. National Asthma Survey.


"Our analysis showed that out of more than 3,000 patients with asthma, obese patients were 66 percent more likely to report continuous symptoms, 36 percent more likely to miss more days of work and 52 percent more likely to be classified as having either moderate or severe persistent asthma when compared to non-overweight people," Dr. Brian Taylor, a pulmonary fellow, said in a prepared statement.

These findings held true after the researchers adjusted for factors including gender, race, age, smoking status, and family history of asthma.

Taylor said he and his colleagues, "noted that obese patients were more likely to have less education, be unemployed and be African-American."

They also found that obese people with asthma made more frequent emergency room visits and used daily controller and as-needed rescue medications more often. The association between obesity and asthma severity seemed slightly stronger in women than in men, which has been noted in previous studies.
