In a case-referent study encompassing 33 cases and 228 referents the potential risk for asthma and chronic obstructive pulmonary disease and respiratory cancer among workers in a soft paper mill was evaluated. The cases were selected from registers of deaths and burials in the parishes around the paper mill. Information on exposure was obtained from the personnel register of the mill but because of shortage of information the cases could only be classified as "exposed" or "non-exposed." At some places in the mill the concentrations of paper dust had previously been high, 10-30 mg/m3. Employment at the paper mill was found to be associated with an increased risk of bronchial asthma and chronic obstructive pulmonary disease (odds ratio = 3.8, p less than 0.05).
在一项涵盖33例病例和228例对照的病例对照研究中，评估了一家软纸厂工人患哮喘、慢性阻塞性肺疾病和呼吸道癌症的潜在风险。病例选自纸厂周边教区的死亡和埋葬登记册。暴露信息从纸厂的人事登记册中获取，但由于信息不足，病例只能分为“暴露”或“未暴露”。纸厂的某些地方，纸粉尘浓度此前一直很高，为10 - 30毫克/立方米。研究发现，在纸厂工作会增加患支气管哮喘和慢性阻塞性肺疾病的风险（优势比 = 3.8，p < 0.05）。
