WESTPORT, CT (Reuters Health) – In children genetically at risk for asthma, problems with infant caregiving, postpartum depression, and inadequate marital support are associated with asthma at school age, according to the results of a prospective study reported in the October issue of Pediatrics.
Dr. Mary D. Klinnert, of the National Jewish Medical and Research Center in Denver, and colleagues prospectively assessed parenting risk at age 3 weeks for 145 infants whose mothers had asthma. Twenty-eight of the infants also had a father with asthma. By 6 to 8 years of age, 28% of the children had a physician diagnosis of asthma, had had wheezing documented, and/or had been prescribed asthma medication.
Univariate analysis revealed three variables in the first year of life that predicted asthma status between ages 6 and 8 years: elevated IgE levels at 6 months of age, global ratings of parenting difficulties at 3 weeks of age, and higher numbers of respiratory infections during the first 12 months of life. Multivariate analysis confirmed that 6-month IgE (odds ratio 2.15) and parenting difficulties (odds ratio 2.07) were significant risk factors.
Dr. Klinnert suggested to Reuters Health that the initial manifestation of the pattern of parenting may be related to parents' prompt and effective response to an infant's illness. "Therefore, the infants become less sick; there's less inflammation in lungs. That's one possible mediating process for reducing the risk of asthma onset."
"It's important for physicians to be aware of parents who are having difficulty after the baby is born and during the first year of life," she emphasized. "We need to reinforce the importance of supporting and educating the parents of young children."
She was quick to add, however, that her study should not result in "mother-bashing."
"It is not the mother's fault if the child develops asthma," she said pointedly. "Parental coping is simply one more variable to be added to the list of environmental factors that contribute to asthma."
