2005年四川省大骨节病监测结果分析

Analysis on Monitoring Data of Kashin-Beck Disease in Sichuan Province in 2005

目的了解四川省大骨节病病情。方法随机抽取6个大骨节病活跃病区县进行儿童右手X线检查和成人大骨节病病情调查,采集儿童发样及当地主食粮样进行硒含量检测。结果①儿童X线检出率平均4.86%(0.96%～6.93%);②成人大骨节病平均患病率32.10%,其中Ⅰ度患病率17.2%,Ⅱ度患病率10.2%,Ⅲ度患病率4.8%;各地区中若尔盖患病率最高,达50%,壤塘、色达、阿坝、旺苍、汉源患病率分别为41.0%、33.3%、30.4%、24.4%、15.8%;③儿童发硒水平平均为0.270±0.079mg/kg;④粮食硒含量平均为0.0123±0.0102mg/kg。结论所调查地区儿童大骨节病病情处于控制或基本控制范围,但仍然有新发,成人大骨节病病情较为严重。

Objective To understand the pathogenetic condition of Kaschin-Beck Disease （KBD） in Sichuan province. Methods Six active epidemic counties of KBD were selected by random sampling. X-ray examination on children＇ right hand was done and the pathogenetic condition of Kaschin-Beck Disease among adults was investigated. The selenium level was detected through collecting children＇ hair and local staple food. Results ①The average detection rate of X-ray examination done on children was 4.86% （0.96% - 6.93% ）; ②The average prevalence rate of Kashin-Beck Disease among adults was 32.10%. Among them, the prevalence rate of Ⅰ degree was 17.2 %, Ⅱ degree was 10.2 % and Ⅲ degree was 4.8 %. The prevalence rate of Ruoergai county was 50%, the highest of all. And the prevalence rate of other 5 countie-Xiangtang, Seda, Aba, Cangwang and Hanyuan were 41.0 %, 33.3 %, 30.4 %, 24.4 % andl5.8 %, respectively. ③The average hair selenium level was 0.270 ± 0. 079 mg/kg. ④The average content of selenium in staple food was 0. 012 3 ±0. 010 2 mg/kg. Conclusions The pathogenetic condition of KBD among children investigated in the region is in control or basic control, but there are still new cases. And the pathogenetic condition of adults is more serious.
