Abstract: Objective Objective To explore the risk factors of Schistosoma japonicum infection in the residents in Xingzi County，Ji? angxi Province. Methods Methods Six administrative villages from different areas were randomly selected by the cluster sampling meth? od as the study sites in Xingzi Country in 2013，and all the residents aged 5 years or above were investigated epidemiologically， and the schistosome infection was surveyed by Kato?Katz technique. The risk factors of schistosomiasis were analyzed by using the Chi?square test analysis and multivariate Logistic regression model. Results Results In 2013，there were 2 050 residents received the stool examination and 146 persons were positive，the schistosome infection rate was 7.1%. The Chi?square test showed that gender，age，occupation and education level were associated with the population infection rate（χ2 = 26.485、 16.836、 25.700、 90.805， all P < 0.05） . The multivariate Logistic regression mode showed that the probability of schistosomiasis for the male was 3.041 times as much as that for the female；the probability of schistosomiasis for the illiteracy and primary education level crowd was 8.870 times as much as that for the college degree or above crowed；the probability of schistosomiasis for the junior middle school education level crowd was 5.598 times as much as that for the college degree or above crowed；the probability of schistoso? miasis for the high school education level crowd was 2.995 times as much as that for the college degree or above crowed；the probability of infection of fishermen was the highest，which was 3.053 times as much as that for the other professional crowds. Conclusions Conclusions The risk factors of schistosome infection mainly include gender，occupation and the education level. We should strengthen the health education of schistosomiasis control， protection against the infested water contact， and so on.

摘要： 目的 目的 分析江西省星子县居民血吸虫感染的危险因素。 方法 方法 2013年采用整群抽样的方法从江西省星子县 血吸虫病流行区随机抽取6个行政村进行调查， 并采用Kato?Katz法对这6个村 ≥ 5岁的全部常住居民进行病原学检查； 应用单因素 χ2 检验和多因素Logistic回归模型对影响血吸虫病流行的相关危险因素进行分析。 结果 结果 2013年共 粪检调查2 050人， 查出粪检阳性146人， 血吸虫感染率为7.1%。单因素 χ2 检验显示， 不同性别、 年龄、 文化程度、 职业 人群血吸虫感染率差异均有统计学意义 （χ2 = 26.485、 16.836、 25.700、 90.805， P均< 0.05）。多因素Logistic回归分析显 示， 男性感染血吸虫的风险是女性的3.041倍； 小学及以下文化程度人群血吸虫感染风险是大专及以上文化程度人群的 8.870倍； 初中和高中文化程度人群感染血吸虫的风险分别是大专及以上文化程度人群的5.598倍和2.995倍； 渔民血吸 虫感染的可能性最高， 是其他职业的3.053倍。 结论 结论 影响星子县居民血吸虫感染的危险因素主要包括性别、 职业和文 化程度； 应强化血吸虫病健康教育， 加强疫水接触防护工作， 减少血吸虫感染发生。
