Researchers analyzed data from the National Health Interview Survey from 2017-2018 to understand how common asthma is among adults in the United States. They focused on adults aged 18 and older and calculated an age-adjusted percentage of people who reported currently having asthma.
The main finding was that women were more likely than men to currently have asthma. The survey report did not provide specific numbers or percentages for this difference, but it noted the pattern was present in the data. No safety concerns or adverse events were reported, as this was not a treatment study.
It is important to be careful with this information because it comes from an observational survey. This means researchers looked at existing data; they did not test a treatment or follow people over time to see what caused the asthma. The survey shows a link or association, but it cannot prove that being a woman causes asthma. Many other factors could explain the difference.
Readers should take from this that asthma appears to be more common in adult women than men, based on this national snapshot. This is useful for public health awareness but does not provide new medical advice for individuals. More research would be needed to understand the reasons behind this difference.
