Archives of Environmental Health: Effects of the home environment on respiratory symptoms of a general population ...   (Site not responding. Last check: 2007-10-18) Studies of children [5-9] found that the use of gas for cooking or heating was associated with an increased prevalence of cough, wheeze, acute respiratory infections, history of respiratory illness prior to age 2 y, and rate of hospitalization, compared with the use of electric stoves for cooking or heating. Fuels that were different from natural gas, e.g., bottled gas, kerosene, coal, or oil, and heating appliances that differed from central heating (i.e., water-heat transfer) were associated with an increased prevalence of chronic cough, phelgm, wheeze, dyspnea, rhinitis, and cardiovascular disturbances. The aim of this study was to determine if the fuel for cooking or for heating, and type of heating, are associated with increased prevalence rates of respiratory symptons in a general population sample in an urban-suburban environment. www.findarticles.com /p/articles/mi_m0907/is_n1_v47/ai_12009488   (1201 words)
