摘要: Background Asthma in school children is rising, and indoor allergens are very common triggers of asthma attacks; however, the risk environment on has not been well studied. Objective To determine presence levels aeroallergens schools, where prevalence rates high. Methods Settled dust samples were collected from 12 Baltimore City public elementary they analyzed for following allergens: cockroaches (Bla g 1/2), mites (Der f 1/p 1), dog (Can cat (Fel d mouse (Mus m 1). School correlated with allergen levels, association between other factors present schools' was examined. Results The mean range 1.49 U/g (0 to 8) Bla 1/2; 0.38 μg/g 11.9) Der 1; 1.44 (0.1 9.6) Can 1.66 (0.2 12) Fel 6.24 (0.3 118.3) Mus 1. Dust mite, significantly rooms carpet and/or area rugs, compared bare floors ( P = 0.001). Conclusions Common that known trigger detected all environments, However, overall low, indicating factors, including exposures homes asthmatic patients, may have more relevance sensitization symptoms than exposures.
