Sydney, June 29 (IANS) Avoiding house dust mites (HDM) or modifying diets may not help prevent the onset of asthma in high-risk children, says a new study.
Doctor Guy Marks from the Woolcock Institute of Medical Research and other researchers studied the role of early exposure to environmental factors in the development of asthma. They recruited over 600 newborn children with a family history of asthma in western and southwestern Sydney, reported the science portal EurekAlert.
The study was designed specifically to test HDM avoidance and dietary fatty acid modification as interventions to prevent asthma and allergic disease in children with a family history of asthma and wheezing.
Published in the July 2006 edition of the Journal of Allergy and Clinical Immunology, the study found that avoiding HDM allergens from birth does not prevent the onset of asthma, eczema or atopy in high-risk children.
Also found to be ineffective was modifying a child's diet to increase the consumption of omega-3 fatty acids, which are found in high concentrations in oily fish, the researchers said.
The study's results suggest further research is required to establish what other interventions can be recommended for the prevention of asthma and allergic disease.
