摘　　要：目的建立科学、客观、可操作性强的血吸虫病疫情评价指标体系,为修订《血吸虫病控制和消灭标准》(GB15976-2006)提供参考依据。方法采用文献查阅法设计调查问卷,选择20位从事血吸虫病防治、科研和管理的专家进行德尔菲法调查,对血吸虫病疫情指标的重要性进行评分,建立血吸虫病疫情评价指标体系并计算体系中各指标的归一化权重和组合权重。结果经过2轮调查,确立了包括3个一级指标和7个二级指标的血吸虫病疫情评价指标体系。居民病情、家畜病情和螺情等3个一级指标的归一化权重分别为0.360 2、0.335 2、0.304 6。二级指标中,家畜感染率的组合权重最高,为0.335 2;钉螺感染率组合权重最低,为0.093 3。结论建立的血吸虫病疫情评价指标体系指标合理、全面、权威性强,可为《血吸虫病控制和消灭标准》修订提供参考依据。Objective To establish a scientific, objective and operational assessing system for schistosomiasis endemicity, so as to provide a scientific evidence for revising the current Criteria for Control and Elimination of Schistosomiasis in China （GB 15976-2006）. Methods A questionnaire was designed based on reference review and 20 scientists working in the field of schisto- somiasis control, research or management were investigated by using the Delphi method. The importance of each index reflecting the endemicity of schistosomiasis was scored by each scientist. The assessing system for endemicity of schistosomiasis was estab- lished and the normalized weight and combined weight were calculated. Results The assessing system included three indices in the first grade and seven indices in the second grade. Among the indices in the first grade, the normalized weights of infection sta- tus of human beings, infection status of livestock, and Oncomelania snail＇ s status were 0.360 2, 0.335 2, and 0.304 6, respec- tively. Among the indices in the second grade, the prevalence of livestock showed the highest combined weight of 0.335 2 while the infection rate of snails showed the lowest score of 0.093 3. Conclusions The indexes of the assessing system for the endemici- ty of schistosomiasis established are reasonable, comprehensive, and authoritative, which provide the scientific evidence for revising the currently available Criteria for Control and Elimination of Schistosomiasis in China.
