In a cohort study of 5464 union organised Swedish chimney sweeps employed at any time between 1918 and 1980 mortality was studied from 1951 to 1982 with national statistics used as a reference. Follow up was possible for 98.6% of the individuals: 717 deaths were observed against 540 expected. There was an increased mortality from coronary heart disease, respiratory diseases, and several types of malignant tumours. Lung cancer mortality was significantly increased and positively correlated to the number of years employed. A fivefold risk increase for oesophageal cancer and liver cancer was found. The increased mortality could be attributed to exposure to combustion products in the work environment but not to smoking habits.
在一项队列研究中,对1918年至1980年间受雇于瑞典工会组织的5464名烟囱清洁工进行了研究,以国家统计数据为参考,研究了1951年至1982年期间的死亡率。98.6%的个体能够被随访:观察到717例死亡,预期为540例。冠心病、呼吸系统疾病和几种恶性肿瘤的死亡率有所上升。肺癌死亡率显著增加,且与工作年限呈正相关。发现食管癌和肝癌的风险增加了五倍。死亡率的增加可归因于工作环境中接触燃烧产物,而非吸烟习惯。
