3家建筑陶瓷企业工人呼吸功能影响因素的logistic回归分析

Logistic regression analysis on influencing factors of pulmonary function of workers in three architectural ceramics factories

目的探讨建筑陶瓷工人呼吸功能异常的相关危险因素,为保障建筑陶瓷工人的健康提出合理建议。方法选择3家建筑陶瓷企业289名接触粉尘的工人为调查对象,了解工人的人口学资料、生活习惯、作业情况、工作环境、防护用品的使用情况和肺功能健康检查等指标,进行单因素分析和非条件多因素logistic回归分析。结果单因素分析显示,工龄、吸烟、使用电风扇、使用局部通风排气设备和粉尘浓度与肺通气障碍有关,差异有统计学意义(P<0.05)。非条件logistic回归分析显示,工龄、吸烟、使用电风扇和粉尘浓度增高为肺通气障碍危险因素,局部通风设备是肺功能障碍的保护因素。结论接触粉尘危害建筑陶瓷工人的健康,应当引起重视,须对作业工人加强宣传和防护。

Objective To explore the related factors influencing pulmonary function of architectural ceramics workers to provide rational suggestions for protecting their health. Methods 289 dust exposed workers from three architectural ceramics factories were taken as the subjects. Their living styles, demographic data, job situation, working environment, and the use of personal protective devices and pulmonary function were investigated, and logistic regression analysis was conducted for single and unconditional multiple factors. Results The single factor analysis results showed that working age, smoking habit, use of electric fan and local exhaust ventilation equipment and the dust concentrations were correlated with pulmonary function, the difference was statistically significant （P%0.05）. The unconditional logistic regression analysis showed that working age, smoking habit, use of electric fan and dust concentrations Increase were factors influencing the pulmonary function, Local ventilation equipment is the protective factorof pulmonary dysfunction. Conclusions More attention should be paid on the health of dust exposed workers, and made them to raise their awareness of the hazardous effects of the dust and to consciously protect themselves.
