The relationship between exposure to cement dust in a Portland cement factory and later hospitalization due to respiratory disease and in particular chronic obstructive lung disease (COLD) was examined in a cohort initially examined in 1974. A total of 546 men with different lengths of employment in the cement factory were compared with 857 randomly sampled men of the same age from the same geographical area. Information on hospitalization was obtained from a nationwide register administered by the Danish National Board of Health. During a 9-year, 8-month period, 7.8% of the total population studied had been admitted to hospital at least once because of respiratory disease and 4.3% had been admitted because of COLD. Cement workers had no increased rates of hospitalization when compared with other blue collar workers from the random sample or the whole random sample. A vague tendency towards increasing rates of hospitalization due to COLD with increasing duration of exposure to cement dust up to 30 years was found. Given at least one hospitalization, exposure to cement dust was not related to the accumulated number of days in hospital in the observation period. We conclude that long-term exposure to cement dust does not lead to higher morbidity of severe respiratory disease than other types of blue collar work.
在一项始于1974年的队列研究中，对一家波特兰水泥厂工人接触水泥粉尘与之后因呼吸系统疾病尤其是慢性阻塞性肺病（COLD）住院之间的关系进行了调查。将水泥厂中546名工作年限不同的男性工人与来自同一地理区域、年龄相同的857名随机抽样男性进行了比较。住院信息来自丹麦国家卫生局管理的全国登记册。在9年8个月的时间里，研究总人口中有7.8%至少因呼吸系统疾病住院一次，4.3%因COLD住院。与随机样本中的其他蓝领工人或整个随机样本相比，水泥工人的住院率没有增加。发现接触水泥粉尘长达30年，因COLD导致的住院率有逐渐上升的模糊趋势。在至少有一次住院的情况下，接触水泥粉尘与观察期内累计住院天数无关。我们得出结论，长期接触水泥粉尘不会比其他类型的蓝领工作导致更严重的呼吸系统疾病发病率。
