Stress link to asthma?

According to a recent study published in the January issue of the American Journal of Respiratory and Critical Care Medicine, children whose mothers are chronically stressed are more likely to have asthma than children whose mothers are not. According to Anita Kozyrskj, Ph.D., Associate Professor at the University of Manitoba, “It is increasingly clear that traditional environmental risk factors do not fully explain the origins of asthma‚Ķ evidence is emerging that exposure to maternal distress in early life plays a causal role in the development of childhood asthma. In a cohort of children born in 1995, we found that maternal distress which persists beyond the postpartum period is associated with an increased risk of asthma at school-age.” The researchers analyzed the medical records of almost 14,000 children native to Manitoba who were registered with Manitoba Health Services from birth in 1995 to 2003 to determine the presence of asthma at age seven. The following is an excerpt of an article from Medical News Today that reviews the study:

Dr. Kozyrskyj and her colleagues analyzed the medical records of nearly 14,000 children born in Manitoba in 1995 who were continuously registered with Manitoba Health Services until 2003. They determined whether the children had current asthma at age seven by analyzing records of doctor visits, hospitalizations and medications in the year of the child’s seventh birthday, and related it to maternal distress as defined by doctor visits, hospitalizations and medication for depression and anxiety. Maternal distress was categorized according to onset and duration into four categories: no distress, postpartum distress only, short-term distress and long-term distress.
