为探讨燃煤型砷中毒流行因素的作用 ,用累积比数模型对 15 1例不同程度砷中毒患者、16例病区内对照、5 3例病区外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 )。提示应采取综合措施来预防燃煤型砷中毒
To explore the role of coal-burning arsenic poisoning epidemic factors, the cumulative ratio model was used to analyze the exposure factors of 151 patients with different degrees of arsenic poisoning, 16 controls in the ward, and 53 controls in the ward. The results showed that the risk factors according to the size of the effect of burning high-arsenic coal, poor ventilation, arsenic and urine total arsenic load, smoking, fluorosis (OR> 1, P <0 05); Educational level and family economic status (OR < 1, P <0 05). Prompt to take comprehensive measures to prevent coal-fired arsenic poisoning
