目的通过对1990~2012年大骨节病监测结果进行分析,掌握山西省大骨节病病情动态及消长趋势,为实现基本消除大骨节病防治目标提供依据。方法按照全国大骨节病监测方案要求,统一标准和方法。对监测点7~12岁儿童进行临床检查及右手正位X线检查,个别年份进行全体居民或16岁以上成人临床检查。结果 1990、1999年2个定点监测点大骨节病Ⅰ度以上临床患病率分别为24.93%、11.70%和10.60%、8.20%;2008年成人大骨节病共计调查了13 871人,临床检出人数801人,检出率为5.77%。7~12岁儿童临床及X线检查结果显示,1994~2012年所有监测点临床未检出阳性病例;1992~2012年X线阳性率全部<5%,骨端阳性率<3%。结论山西省大骨节病从20世纪90年代起病情持续下降,现已处于稳定控制态势,“十二五”末能够达到基本消除大骨节病的阶段目标。
Objective To analyze the surveillance results of Kashin-Beck disease from 1990 to 2012 and to grasp the trends of Kashin-Beck disease prevalence in Shanxi Province and the trends of its growth and decline, so as to provide the basis for the basic prevention and control of Kashin-Beck disease.
