SUNDAY, Feb. 28 (HealthDay News) — Exposure to unclean conditions early in life doesn’t affect a child’s risk of developing asthma, researchers say.
“In an earlier study, we found that infants were exposed to high levels of endotoxin and allergens [mite and cockroach] in their day-care centers. Therefore, we were anxious to find out, through a birth cohort study, if infants from low-income families with high risk of asthma might be protected from the development of the disease,” lead author Vera E.V. Rullo said in a news release.
