Lucie Blais, MD, Université de Montréal, and Hôpital du Sacré-Cœur de Montréal, Montréal, Quebec, and colleagues found that 32.6% of children born to mothers who neglected to treat their asthma during pregnancy developed the respiratory illness themselves. “Uncontrolled maternal asthma during pregnancy could trigger a transient yet important reaction in the foetus that affects lung development and could subsequently increase the likelihood of a baby developing asthma in later childhood,” said Dr. Blais. As part of the study, the research team examined a decade of health records for 8,226 children -- from birth to 10 years of age -- born to asthmatic mothers. Parents of these children were also mailed questionnaires requesting additional facts concerning familial medical history, lifestyle habits, and environment. “We found that failing to control maternal asthma during pregnancy clearly has an impact on asthma in offspring -- a consequence that is independent of other contributing factors,” says Dr. Blais. “It is of great importance for physicians to adequately treat asthmatic mothers during pregnancy, not only for the favourable outcome of pregnancy but also for the benefit of the child.” SOURCE: University of Montreal
