燃煤型砷中毒流行因素的多变量分析

Multivariate analysis of epidemic factors in arsenism cansed by burning coal.

探讨燃煤型砷中毒流行因素的作用。方法用单因素及多因素非条件Logistic回归模型对 15 1例砷中毒患者和 6 9例对照的暴露因素进行了分析。结果发现危险因素按作用大小依次是燃用高砷煤的年限、居室通风情况差、发砷及尿总砷负荷高、吸烟、氟中毒 (OR >1,P <0 0 5 ) ;影响因素有文化程度和家庭经济状况 (OR <1,P <0 0 5 )。结论提示应采取综合措施来预防燃煤型砷中毒。

Objective To study the effect of epidemic factors on arsenism cansed by burning coal.Method The exposure factors of 151 patients and 69 controls were evaluated with single factor non conditional logistic regression and multivariate non conditional logistic regression model.Result The results suggested that the major risk factors as listed in a order of their effect on arsenism were, period of burning hyperarsenic coal, bad roon ventilation, high arsenic content in hair and urine, smoking, and fluorosis (OR>1,P<0.05).The contributin factors were educational level and family economy state (OR<1,P<0.05).Conclusion lt is suggested that multiple measures be adopted to prevent arsenism by burming coal.
