Self-reported home environmental risk factors for childhood asthma: A cross-sectional study of children in Buffalo, New York

We present prevalence estimates of indoor and outdoor environmental risk factors for asthma from a cross-sectional study of children 1 to 17 years of age living in Buffalo, New York. A child's primary caretaker completed a questionnaire about the household's demographics, lifestyle habits, housing, indoor and outdoor environment, and the child's activity patterns, family history of asthma, asthma symptoms and treatment, and medical care access. Significant environmental risk factors were presence of smokers in the household, humidifier or vaporizer use, chemical odors indoors, frequent truck traffic, and chemical odors outdoors. Most of these risk factors can be mitigated or controlled.
