An Australian study has found that toddlers with a sensitivity to house dust mites have an increased risk of developing asthma.
The study, published online in the Journal of Allergy and Clinical Immunology, included 620 children with a family history of allergies who were followed from birth to age 12. The children were given a skin prick test at ages 6 months and 1 and 2 years to check for sensitivity to different allergens and then tested at age 12 for asthma.
Asthma was diagnosed in 75 percent of the children who tested positive for sensitivity to house dust mites when they were infants, compared with 36 percent of those who didn't have a sensitivity to dust mites.
Dr. Caroline Lodge, of the School of Population Health at the University of Melbourne, told Medical ID wearers that identifying groups of high-risk children may help researchers learn more about asthma development and find ways to prevent it.
