A cross-sectional study including 54 furniture factories and three control factories was conducted to survey lung function and prevalence of respiratory symptoms among woodworkers. Spirometry was performed on 2423 persons. Questionnaires regarding respiratory symptoms and wood dust exposure were completed by 2033 woodworkers and 474 controls. Personal passive dust measurements were performed on 1579 persons. The arithmetic mean +/- SD for equivalent inhalable dust was relatively low (1.19 +/- 0.86 mg/m3). Woodworkers had increased frequency of coughing with negative interaction between dust exposure and smoking. A dose-response relationship was seen between dust exposure and asthma symptoms, and a positive interaction for asthma was seen between female gender and dust exposure. Increased frequency of wheezing and a cross-shift decrease in forced expiratory volume in 1 second among workers using pinewood was seen. In conclusion, wood dust exposure might cause respiratory symptoms, despite a relatively low exposure level.
开展了一项横断面研究，纳入54家家具厂和3家对照工厂，以调查木工的肺功能及呼吸道症状患病率。对2423人进行了肺活量测定。2033名木工和474名对照完成了关于呼吸道症状和木尘暴露的问卷调查。对1579人进行了个人被动粉尘测量。等效可吸入粉尘的算术平均值±标准差相对较低（1.19±0.86毫克/立方米）。木工咳嗽频率增加，粉尘暴露与吸烟之间存在负相互作用。粉尘暴露与哮喘症状之间存在剂量反应关系，女性性别与粉尘暴露之间对哮喘存在正相互作用。使用松木的工人中喘息频率增加，一秒用力呼气量出现跨班次下降。总之，尽管暴露水平相对较低，但木尘暴露可能会导致呼吸道症状。
