北京市怀柔区消除大骨节病评估模式探讨

Study on the evaluation model for eliminating Kaschin-Beck disease in Huairou district ,Beijing

目的通过对消除大骨节病区评估工作的讨论分析,探讨消除大骨节病区监测评估模式的可行性和有效性。方法对全区大骨节病病区30年监测、干预、调查结果数据及各类信息进行汇总分析。结果怀柔区大骨节病区建立了政府主导下的大骨节病防治组织领导体系。32年中临床监测总人数21 968人次,X线手片监测5 935人次。以5年为一个阶段,临床检出率由最高34.92%降至最低3.05%,下降了11.5倍。X线检出率由最高23.66%降至最低的1.19%,下降了19.9倍。特别是近10年,年均临床检出率4.33%,X线检出率1.27%。7～12岁儿童发硒检测结果最小值0.209μg/g,最大值0.508μg/g,中位数0.3397±0.0064μg/g。经过综合防控,居民口粮非病区输入大米占52.93%,面粉33.58%,两项合计占86.51%,本地玉米、小米等杂粮占13.49%。结论怀柔区不具备大骨节病病区存在条件,予以消除。评估模式切实可行,结论客观权威。

Objective Discussing the evaluation model＇s feasibility and effectiveness for eliminating Kaschin - Beck disease （KBD） monitoring region, through study and analysis the assessment data of KBD in this region. Methods Analyzed the data which gathered from moniloring, intervention and survey in KBD endemic area for 30 years. Results In Huairou district KBD endemic area established a government - led system to prevent and cure KBD. 32 years of clinical monitoring of a total number of 21,968 people arid the X - ray monitoring of 5 935 people. 5 years as a stage of clinical, detection rate decreased from the max rate of 34.92% to a minimum of 3.05%, declined by 11.5 times. X - ray detection rate from 23.66% down to a minimum of 1. 19%, a decline of 19.9 times. Especially in the recent 10 years, the average annual rate of clinically detected stable at about 4. 33%, the X - ray detection rate remained stable at about 1.27%. 7 to 12 years old children＇ s hair selenium test results to minimum content was 0. 209 μg/g, the max was 0. 508μg/g, the median was 0. 3397 ± 0.0064 μg/g. After a comprehensive prevention and control, non - KBD endemic area input food in a very large percent, rice accounted for 52.93% and flour accounted for 33.58%, the two together for 86.51%. At the same time, local corn, millet and other grains only accounted for 13.49%. Conclusion Huairou district doesnt have KBD endemic area recently. This assessment model discussed in this paper was feasible and couht find out authoritative conclusions.
