RESPIRATORY EFFECTS OF HOUSEHOLD EXPOSURES TO TOBACCO-SMOKE AND GAS COOKING

Abstract

Residents (1724) of Washington County, Maryland [USA], who had participated in 2 studies of respiratory symptoms and ventilatory function were analyzed to evaluate the effects of exposures at home to tobacco smoke generated by other members of their households and to fumes from the use of gas as a cooking fuel. Currently smoking subjects showed the highest frequency of these findings, and persons who had never smoked had the lowest prevalence of abnormal respiratory findings. The presence of a smoker in the household other than the subject was not associated with the frequency of respiratory symptoms and only suggestively associated with evidence of impaired ventilatory function among men, being most marked among men who had never smoked. There was no evidence that cooking with gas was harmful to women.
