We aimed to study the associations between the household use of cleaning sprays and asthma symptoms and control of asthma, in females from the Epidemiological Study on the Genetics and Environment of Asthma (EGEA). Data were available for 683 females (mean age 44 yrs, 55% never smokers, 439 without asthma and 244 with current asthma). Both domestic exposures and asthma phenotypes (asthma symptom score, current asthma, poorly-controlled asthma (56%)) were evaluated as previously described in the European Community Respiratory Health Survey. Associations between the use of sprays and asthma phenotypes were evaluated using logistic and nominal regressions, adjusted for age, smoking, body mass index and occupational exposures. Significant associations were observed between the weekly use of at least two types of sprays and a high asthma symptom score (OR (95% CI) 2.50 (1.54-4.03)) compared with a null score. Consistent results were observed for current asthma (1.67 (1.08-2.56)) and poorly-controlled asthma (2.05 (1.25-3.35)) compared with females without asthma. The association for current asthma was higher in females not reporting avoidance of polluted places (2.12 (1.27-3.54)) than in those reportingsuch avoidance (0.99 (0.53-1.85)). The common use of household cleaning sprays is positively associated with a high asthma symptom score, current asthma and poorly-controlled asthma in females.

STUDY OBJECTIVE: To report the occurrence of persistent respiratory disorders, including irritant-induced asthma, among adults living and working near an environmental spill of the pesticide, metam sodium, after the derailment of a tank car.
DESIGN: Retrospective clinical case series.
SETTING: California communities situated within one-half mile of the Sacramento River, from Mt. Shasta City to Shasta Lake.
PATIENTS: 197 adults referred to a university occupational/environmental health clinic or to a private occupational/environmental health practitioner for evaluation of health problems potentially related to the spill.
MEASUREMENTS AND RESULTS: History, physical examination, review of medical records, spirometry, and methacholine challenge testing revealed 20 cases of persistent irritant-induced asthma and 10 cases of persistent exacerbation of asthma.
CONCLUSIONS: This is the first reported series of cases of persistent irritant-induced asthma involving both community residents and occupationally exposed individuals.
