目的了解甘肃省大骨节病病情现状和消长趋势,科学评估防控效果。方法选择甘肃省7个市(州)37个大骨节病病区县,每个县抽取5个重病区乡(镇),每个病区乡(镇)抽取3个重病区村作为调查点开展7~12岁儿童临床及右手X线拍片检查,同期开展防控措施落实情况调查。结果共调查7个市(州)、37个病区县、171个病区乡、571个病区行政村、7~12岁儿童27 966人,临床检出患者14人,检出率0.05%,均为I度大骨节病患者;X线检出阳性病例353人,检出率1.26%,其中干骺端检出率1.25%,骨端检出率0.01%,三联征检出率为零。4.90%(28/571)的病区村未达到大骨节病控制标准。病区居民以自产小麦面粉为主(78.18%);病区综合防治措施以退耕还林为主,占原有耕地的15.06%。结论甘肃省大骨节病病情处于稳中有降的趋势,应继续加强重点病区病情监测和综合防控措施的落实。
