Program Reduces Asthma in Children(June
3, 2005 – NEWSdial.com)
An asthma intervention program applied during the first year
of life significantly reduced the prevalence of asthma in high
risk children at 7 years of age, according to a new study featured
on the online version of the Journal of Allergy & Clinical
Immunology (JACI). The JACI is the peer-reviewed journal of
the American Academy of Allergy, Asthma & Immunology (AAAAI).
Moira Chan-Yeung, MB, and colleagues from the Canadian Childhood
Asthma Prevention Study, studied high risk infants with an immediate
family history of asthma and allergies. The children were assigned
to either a study or control group.
In the study group, intervention measures were introduced before
birth and during the first year of life. These included avoidance
of house dust mites, pets and secondhand smoke, encouragement
of breast feeding, and delayed introduction of solid foods during
the first 12 months of life.
At age seven, 469 children completed a questionnaire asking
about respiratory symptoms, and the frequency, severity and medication
for treatment of wheezing attacks in the last 12 months. Three
hundred eighty of the children returned for further assessment
by a pediatric allergist and underwent breathing tests to determine
the degree of airway hyperresponsiveness, a typical feature of
The study found that the intervention measures significantly
reduced the frequency of asthma by 56%. The prevalence of asthma
was significantly lower in the intervention group than in the
control group (14.9% vs. 23%).
Researchers hypothesized that an intervention during the first
year of life has the potential for long-term medication of an
infants risk for asthma development. They plan to assess the
children at 11 to 12 years to determine whether the intervention
program can be effective in decreasing the lifelong risk for
asthma or if it has merely postponed the onset of the disease.
