Information about occupation and industry of cancer patients is routinely recorded in the Cancer Registry of Tianjin, People's Republic of China. Occupational risk factors of lung cancer for the period of 1981-1987 were assessed using other cancers as controls. For each occupation and industry, workers employed in it were considered exposed and were compared with all other workers. Elevated risks were found for a number of industries for both sexes, including, in particular, the textile, wood, metal, and construction industries. Results by occupation were similar to those by industry. Smoking scores were calculated for various occupations on the basis of a separate population survey in Tianjin. Smoking cannot explain the elevated odds ratios in males, while among females a strong correlation was observed between smoking scores and lung cancer odds ratios, suggesting a confounding effect.
中国天津市癌症登记处会定期记录癌症患者的职业和行业信息。以其他癌症患者作为对照，评估了1981年至1987年期间肺癌的职业危险因素。对于每个职业和行业，从事该职业和行业的工人被视为暴露人群，并与所有其他工人进行比较。发现多个行业的男性和女性患癌风险均有所升高，尤其是纺织、木材、金属和建筑行业。职业方面的结果与行业方面的结果相似。根据天津市另一项独立的人口调查，计算了不同职业的吸烟得分。吸烟无法解释男性患癌比值比升高的情况，而在女性中，吸烟得分与肺癌比值比之间存在很强的相关性，表明存在混杂效应。
