Background: Hypersensitivity to dust mites, mold and pet dander found in the home is common among patients with asthma. Home environmental control to reduce exposure to allergens is one of various therapeutic measures that can be taken. Objectives: To determine the prevalence of adequate home environmental control among a study population monitored by the Family Health Program and to identify any possible correlation with the exacerbation of asthma among children between the ages of 5 and 14 in the city of Camaragibe, located in the state of Pernambuco, Brazil. Method: A transversal study was carried out involving 210 mothers/guardians of children, to whom International Study of Asthma and Allergies in Children questionnaires were administered in order to characterize the exacerbation of asthma attacks. The Environment Assessment Guide of Allergic Patients was used to assess the bedrooms and living rooms in the home. Results: Among the 210 asthmatic children and adolescents evaluated in 2001, adequate home environmental control was observed in 141 (67.1%), and no correlation was observed between the degree of environmental control and fewer (< 3) asthma attacks (p = 0.39). Regarding the rooms where the asthmatic patients sleep, inappropriate furnishings were found in the homes of 93 patients (44.3%), including rag curtains in 84 cases (40.2%). Passive smoking was reported in 77 cases (36.7%). Conclusion: The level of home environmental control was satisfactory in the great majority of the residences, which may have contributed to the fact that no correlation was found between home environmental control and lower frequency of acute asthma attacks among the population studied.
