目的了解山西省大骨节病病情,为防治工作提供科学依据。方法按照《2012年医改地方病防治项目实施方案》的要求,在全省抽取18个县,每个县抽取5个乡,每个乡抽取3个村,调查病区村大骨节病防控措施落实情况,包括调查点的人口、耕种、主食以及其他防治措施等落实情况,并对调查村所有7~12岁儿童开展临床和X线检查。结果共调查18个县514个村,病区人口32.31万人;病区实施了病区村搬迁81个,搬迁22 832人;退耕还林还草150 965亩,占耕地面积的56.00%,改种经济作物68 473亩,占耕地面积24.90%,异地育人3 203人;近几年未采取补硒措施;调查了211个病区村病情,检查7~12岁儿童6 793人,临床未检出阳性病例;X线检出阳性4例,均为单纯干骺端改变,检出率为0.06%(4/6 793),未检出骨骺、骨端及腕骨阳性儿童。结论山西省儿童大骨节病病情已经控制,处于持续稳定状态,由于大骨节病致病因子仍然存在,需继续加强大骨节病的病情监测工作。
