Depression of the mother triggers the baby's asthma
According to a new study by a group of Canadian researchers, children whose mothers are stressed are at high risk of developing asthma, Reuters Health reports.
The researchers say that prolonged exposure of the child to sources of stress such as depression or anxiety of the mother, increases the risk of developing asthma by up to 25%.
The researchers argue that traditional asthma trigger factors do not fully explain the occurrence of asthma.
The research group analyzed the medical records of almost 14,000 children born in 1995. They checked whether these children developed asthma at the age of 7, following the records of doctor visits and possible hospital admissions.
They compared this data with the mother's medical records: doctor visits, hospital admissions and medication for depression or anxiety. Then, the mother's illnesses were divided according to the duration and treatment: without depression, postpartum depression, short-term depression and long-term depression.
The researchers found that the depression of the mother who exceeded the duration of the postpartum period is associated with an increased risk of the baby to develop asthma.
Although the reason for the increased risk of asthma in these situations is unclear, the researchers say it may be because of depression, the mother will not breast-feed the baby and the likelihood of smoking is higher.
