The study aims to survey the mortality from asthma in different occupations among Swedish men. The design was a register based cohort study where the smoking adjusted mortality due to asthma among Swedish men 1971-80 was investigated. For each occupation a smoking adjusted standardised mortality ratio (SMR) was calculated based on a linkage between official mortality statistics 1971-80 and occupational information in the 1970 national census. The information about the smoking habits among different occupations was obtained from a smoking survey carried out in 1963. In the statistical analysis only occupations with more than 10 deaths were considered. A significantly increased mortality from asthma was found among farmers (smoking adjusted SMR 137, 95% confidence interval (95% CI) 115-156), farm workers (smoking adjusted SMR 170, 95% CI 107-235), woodworking machine operators (smoking adjusted SMR 226, 95% CI 108-344), clerical workers (smoking adjusted SMR 161, 95% CI 102-220), packers and labellers (smoking adjusted SMR 144, 95% CI 100-188), and watchmen (smoking adjusted SMR 212, 95% CI 104-320). Exposure to organic dust, such as fresh wood dust and dusts in the farming environment, may cause increased mortality due to asthma.
该研究旨在调查瑞典男性不同职业中哮喘导致的死亡率。研究设计为基于登记的队列研究，调查了1971年至1980年瑞典男性因哮喘导致的吸烟调整死亡率。对于每个职业，根据1971年至1980年官方死亡率统计数据与1970年全国人口普查中的职业信息之间的关联，计算出吸烟调整标准化死亡率（SMR）。不同职业吸烟习惯的信息来自1963年进行的一项吸烟调查。在统计分析中，仅考虑死亡人数超过10人的职业。研究发现，农民（吸烟调整SMR为137，95%置信区间（95%CI）为115 - 156）、农场工人（吸烟调整SMR为170，95%CI为107 - 235）、木工机械操作员（吸烟调整SMR为226，95%CI为108 - 344）、文职人员（吸烟调整SMR为161，95%CI为102 - 220）、包装工和贴标签工（吸烟调整SMR为144，95%CI为100 - 188）以及门卫（吸烟调整SMR为212，95%CI为104 - 320）因哮喘导致的死亡率显著增加。接触有机粉尘，如新鲜木屑粉尘和农业环境中的粉尘，可能会导致因哮喘导致的死亡率上升。
