【摘要】 应用一组改水干预前的地方性砷中毒资料 ,计算各发病单位的砷中毒指数。分析砷中毒指数与居民砷中毒检出率、掌跖角化率、水砷含量、尿砷水平、皮肤色素沉着、色素脱失等 ,均显示正相关关系。其中砷中毒指数 (y)与水砷 (x)相的曲线回归方程为 lg(y+0 .0 1) =3.0 16 x- 2 .16 ,两者相关系数为 r=0 .92 0 ;砷中毒指数 (x)与居民砷中毒检出率之间 r=0 .987,两者成直线回归关系 ,y=5 3.8x+1.5 1;砷中毒指数与足跖角化率之间亦呈良好线性关系 ,同样情况亦见于砷中毒指数与尿砷和异常尿砷检出率之间 ,相关系数分别为 0 .95 9和 0 .919。砷中毒指数与以上各指标的相关系数分析 ,P值均小于 0 .0 5 ,且都呈现良好的正相关关系。砷中毒指数以最简便方式概括了发病单位的砷中毒病例及病情程度 ,在比较不同单位病情时 ,比单纯的砷中毒检出率更能反映实际人群受砷危害情况 ,是流行病学研究中一较好的综合指标更多还原

【Abstract】 The relationship between arsenism index, a synthetic index of endemic arsenism, and some epidemiological indices for studying endemic arsenism was analyzed with a group of data from an endemic arsenism area before preventing intervention in Xinjiang. The findings showed that the arsenism index was positively proportional to those common indices (water arsenic level, arsenism incidence, urine arsenic level, the rate of hyperpigmentation and so on),respectively. The authors consider that the index is a better one for appraising arsenism prevalence, and recommend it to the people working in the field of endemic arsenism as a precticable index for their work.更多还原
