Researchers at the Brigham and Women's Hospital and
Harvard Medical School have indicated that boys may only have short-term asthma
as compared to girls.
The study involved 1,041 children, aged 5 to 12 years with mild to moderate persistent asthma. The participants were tested with annual spirometry tests with methacholine to gauge the responsiveness of their airways.
Over the years it was found that while girls required the same dose of methacholine. Boys needed bigger ones indicating they may have combated the disease.
The details appear in the American Journal of Respiratory and Critical Care Medicine.
