Kaschin-Beck disease condition analysis in Hulunbeier city

目的了解呼伦贝尔市大骨节病的病情势态,为今后大骨节病防治决策提供客观依据。方法2005年对呼伦贝尔市8个大骨节病重病村进行病情调查,以7～13岁儿童大骨节病X线检出率为指标,与1999年曾调查过的6个村的历史病情资料进行对比分析。结果1999年6个村的儿童大骨节病X线检出率在4．55％～11．83％,平均为7．66％;而2005年X线检出率在3．22％～10．53％,平均为7．99％。在6个村间隔7年的对比中,病情上升与下降各有3个村,基本呈现稳定态势,差异无统计学意义(P>0．05)。本次调查8个村的7～13岁儿童大骨节病X线检出45人,均系7年后新发病例,以此推算全市646个病村7年中新发病例3 634人,平均每年新发儿童大骨节病519人。结论除继续深入贯彻以换粮为主切断病因链的预防措施外,在合理营养、改善生活方式的基础上,应尽早开展以治疗现患为目的的二级预防,控制病情的发生发展。
