Antioxidants Linked to Lower Asthma Risk
By medinews.com staff writers
Posted on 12 February 2004
A large study of survey data on youths under 17 has shown that increases in
intakes of antioxidants serum beta-carotene, vitamin C, and the trace mineral
selenium were associated with a lower risk of asthma prevalence. The results
were reported in the February 1, 2004, issue of the American Journal of
Respiratory and Critical Care Medicine.
Even stronger asthma associations for these antioxidants were found in
subgroups of young people exposed to passive smoke. Researchers studied U.S.
national survey data on 6,153 young people four to 16 years old. They found
that serum vitamin E had little or no association with asthma, but an increase
in beta-carotene was associated with a 10% reduction in asthma prevalence in
those not exposed to smoke and a 40% reduction in those who were exposed to
passive smoke. The pattern for vitamin C was similar. An increase in selenium
was associated with a 10-20% decrease in asthma prevalence. In youths with
passive smoke exposure, investigators found a 50% reduction in asthma
associated with selenium.
The study was conducted by Dr. Rachel N. Rubin and colleagues at Cornell
University (Ithaca, NY, USA).
