Brief summary

In this study we are testing a public health intervention to reduce the incidence of childhood asthma. The two interventions that we are testing, that is housedust mite allergen avoidance and omega-3 fatty acid supplementation, are based on the strongest risk factors for asthma that have been identified in observational studies to date. This is the first trial in the world to test whether interventions directed at a potent causative factor (housedust mite allergens) or a protective factor (omega-3 fatty acids) can halt or reverse the increasing prevalence of childhood asthma. If either of these interventions is effective, we will have the potential for the very first time to significantly reduce the incidence of asthma in young children.
