Researchers have identified obesity as a health risk for asthma, but a new study revealed that the level of risk differs for men and women. The Centers for Disease Control and Prevention (CDC) released a study in March that looked at the prevalence of asthma from 2011-2014 among adults based on weight. The rate of asthma in adults with obesity is 11 percent compared to 7 percent of adults in the normal weight range. In women with obesity, asthma prevalence was 15 percent–nearly twice that of normal-weight women.
The study revealed very different findings for men–there wasn’t a significant increase in asthma prevalence in obese men versus men in the normal weight range. For children, asthma prevalence is greater in boys than girls but the prevalence of the condition switches when they hit puberty. Researchers don’t know the specific reason for the difference in asthma prevalence among men and women, but it could be related to fat distribution and/or hormonal differences. More research is also needed to determine if weight loss could reduce asthma rates.
