目的　了解慢性咽炎、鼻炎与接触粉尘、毒物关系。方法　使用流行病学方法 ,调查现患率 ,计算暴露因素的比值比 (OR)。结果　接触粉尘、毒物组的现患率为 10 .6 9% ,对照组现患率为 6 .0 7% ,暴露因素的OR为 1.70 (P 0 .0 5 )。职业暴露组现患率为 19.99% ,职业暴露因素的OR为 2 .98(P 0 .0 1)。结论　接触粉尘、毒物与慢性咽炎、鼻炎可能存在一定的关系。 Objective To understand the relationship between chronic pharyngitis, rhinitis and dust and poison. Methods Epidemiological methods were used to investigate the prevalence and to calculate odds ratio (OR) for exposure factors. Results The prevalence of exposure to dust and poison was 10.69% and that of the control group was 6.70%. The OR of exposure was 1.70 (P 0 .05). Occupational exposure group prevalence was 19.99%, occupational exposure factor OR was 2.98 (P 0 .0 1). Conclusion Exposure to dust, poison and chronic pharyngitis, rhinitis may have a certain relationship.
