The relation between respiratory illness and the use of gas for cooking was examined from data on 1565 infants born to mothers who were primigravidas living in Dundee in 1980. Episodes of, and admissions to hospital for, respiratory illness were recorded during the first year of life. Both admissions and episodes were more common in infants from families using gas for cooking or heating than in infants from families using any other type of cooking or heating, but the differences were not significant. Results from this and other studies show that there is probably a small relation between respiratory illness and the use of gas appliances without a flue. To show convincingly whether such a relation exists might require a survey of 18 000-23 000 subjects. Respiratory illness was, however, strongly and positively related to parental smoking, a finding that is often made even in small studies.
利用1980年在邓迪市居住的初产妇所生1565名婴儿的数据，研究了呼吸道疾病与使用燃气做饭之间的关系。记录了这些婴儿在出生后第一年患呼吸道疾病及住院的情况。使用燃气做饭或取暖家庭的婴儿，其住院率和患病发生率均高于使用其他类型做饭或取暖方式家庭的婴儿，但差异不显著。该研究及其他研究结果表明，呼吸道疾病与使用无通风烟道的燃气器具之间可能存在微弱关联。要令人信服地证明这种关联是否存在，可能需要对18000 - 23000名受试者进行调查。然而，呼吸道疾病与父母吸烟呈强烈正相关，即使在小型研究中也经常得出这一结果。
