Children's asthma can be triggered by mothers' stress
General Interest
Children whose mothers are chronically stressed during their early years have a higher asthma rate than their peers, regardless of their income, gender or other known asthma risk factors. Children whose mothers are chronically stressed during its first years have a higher rate of asthma than their peers, regardless of income, gender or other known risk factors for asthma.
"It is increasingly clear that traditional environmental risk factors do not fully explain the origins of asthma," said lead investigator, Anita Kozyrskyj, Ph.D., Associate Professor in the Faculty of Pharmacy at the University of Manitoba, Canada. "It is increasingly clear that the traditional environmental risk factors, not quite explain the origins of asthma," said the lead researcher, Anita Kozyrskyj, Ph.D., Associate Professor of the Faculty of Pharmacy, University of Manitoba in Canada. "Evidence is emerging that exposure to maternal distress in early life plays a causal role in the development of childhood asthma. "Evidence is emerging that exposure to maternal anxiety 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. "In a cohort of children born in 1995, found that maternal anxiety that persists beyond the post-is associated with an increased risk of asthma in school-age."
The findings appeared in the second issue for January 2008 of the American Journal or Respiratory and Critical Care Medicine, published by the American Thoracic Society.

Dr. Kozyrskyj and her colleagues analyzed the medical records of nearly 14000 children born in Manitoba in 1995 who were continuously registered with Manitoba Health Services until 2003. Dr. Kozyrskyj and her colleagues analyzed the medical records of about 14000 children born in Manitoba in 1995 that were recorded continuously with Manitoba Health Services by 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. They determine whether the children had asthma current seven years analyzing records of doctor visits, hospitalizations and medicines in the year the seventh anniversary of the child, and she related to the suffering mother, as defined by the doctor visits, hospitalizations and medications for depression or anxiety. Maternal distress was categorized according to onset and duration into four categories: in distress, postpartum distress only, short-term distress and long-term distress. Maternal distress was ranked in onset and duration in four categories: no pain, anguish post only, short-term and long-term anguish distress.
"Unlike existing studies that have measured maternal stress during the first few years only, the longitudinal nature of our health care study enabled us to characterize maternal distress over time to identify whether it continued," said Dr. Kozyrskyj. "Contrary to existing studies that have measured maternal stress during the early years only, the nature of our health longitudinal study allowed us to characterize maternal danger in the long term to identify if it continued," said Dr. Kozyrskyj.
Even after controlling for the known risk factors of male gender, maternal asthma, urban location and total health care visits, long-term maternal stress was associated with an increase of nearly a third in the prevalence childhood asthma. Even after controlling for risk factors known male, maternal asthma, urban location and visits total health, long-term maternal stress was associated with an increase of almost a third in childhood asthma prevalence. This is the first study of a non-high-risk cohort of children to report an association with childhood asthma.
