To estimate the annual rates of self reported occupational asthma in different occupational groups in Sweden.
All claims of occupational asthma 1990-2 in the Swedish register of reported occupational diseases were classified according to occupation. The number of people employed in each occupational group in the general population was obtained from the 1990 national census. Reporting rates (cases/million/ year) were calculated for each occupation with more than five reported cases, according to sex and age (20 to 64 years, and 20 to 44 years).
1010 cases were reported giving an annual crude reporting rate of 80/million (95% confidence interval (95% CI) 70 to 90). For men, the crude reporting rate was 91/million (95% CI 84 to 98), and for women 70/million (95% CI 80 to 106). The highest reporting rates were among male bakers-(775/million), furnacemen (702/million), male welders (647/million), female chemical and plastic production workers (629/million), and female poultry and dairy farm workers (602/million).
A surveillance system based on self reporting is influenced by considerable bias, especially reporting bias. However, results for the specific occupations with high rates were similar to those found with other surveillance systems. This indicates that our system is a useful one.
估算瑞典不同职业群体中自我报告的职业性哮喘年发病率。
1990 - 1992年瑞典职业病报告登记册中所有职业性哮喘索赔病例均按职业分类。从1990年全国人口普查中获取各职业群体在普通人群中的就业人数。根据性别和年龄（20至64岁以及20至44岁），计算每个报告病例超过5例的职业的报告率（病例数/百万/年）。
共报告1010例病例，年粗报告率为80/百万（95%置信区间（95%CI）70至90）。男性粗报告率为91/百万（95%CI 84至98），女性为70/百万（95%CI 60至80）。报告率最高的职业群体包括男性面包师（775/百万）、司炉工（702/百万）、男性焊工（647/百万）、女性化学和塑料生产工人（629/百万）以及女性家禽和奶牛场工人（602/百万）。
基于自我报告的监测系统受显著偏差影响，尤其是报告偏差。然而，高发病率特定职业的结果与其他监测系统的结果相似。这表明我们的系统是有用的。
