1902 MAR 28 - (NewsRx.com & NewsRx.net) -- Higher perceived stress in caregivers (mostly mothers) of 2- to 3-month-old infants who had a genetic predisposition to asthma and allergy was associated with increased risk of wheezing during the first 14 months of life, according to an article in the American Thoracic Society's peer-reviewed journal.
Writing in the first issue for February 2002 of the American Journal of Respiratory and Critical Care Medicine, Rosalind Wright, MD, of Channing Laboratory, Brigham and Women's Hospital, Boston, along with four associates, studied 496 children (263 males and 233 females) who were recruited from a Boston hospital within 48 hours of delivery from 1994 to 1996.
Of the 496 children, 287 (57.9%) never wheezed within the 14 months, 116 (23.4% ) had 1 reported wheezing episode, 47 (9.5%) had 2, 28 (5.6%) suffered 3, and 18 (3.6%) had 4 attacks.
Higher levels of caregiver stress predicted an increased risk of wheeze in the infants even after controlling for maternal smoking, allergen levels, breastfeeding frequency, number of respiratory infections, birth weight, parental asthma, race/ethnicity, and socioeconomic status.
Both animal and human studies support the idea that caregiver stress may influence the stress response of the child and modify neuroendocrine function during early development, said Wright. For example, the stress response in infants is influenced by family factors in that families showing high stress also have ...
