目的分析学龄儿童日本血吸虫感染率与社区人群感染率之间的相关关系。方法通过检索CNKI和PubMed,收集1990-2009年公开发表的在中国大陆开展的有关年龄分层日本血吸虫感染率的相关文献,采取最小二乘法和极大似然法,以线性回归和logistic回归对学龄儿童与社区总人群、学龄儿童与社区中其他人群日本血吸虫感染率之间的关系进行拟合分析,以期找到最适的回归拟合。结果变换后的logistic回归拟合学龄儿童与社区人群日本血吸虫感染率之间关系的效果最好,回归系数aG、bG、aI、bI、aA、bA值分别为0.4718、6.8462、0.7985、9.6128、0.1619和4.2688。结论学龄儿童日本血吸虫感染率可考虑作为评估中国社区人群日本血吸虫感染率的一个指标。
Objective To analyze the correlation between Schistosoma japonicum infection rate and community population infection rate in school-age children. Methods The CNKI and PubMed were searched to find out the published literature about the infection rate of schistosomiasis japonica in Chinese mainland published in mainland China from 1990 to 2009. Least square method and maximum likelihood method were used to analyze the linear regression and logistic regression The relationship between schistosomiasis infection rate among school-age children, general community population, school-age children and other populations in the community was fitted to find the best regression fit. Results The logistic regression after the transformation fitted the best correlation between schistosomiasis infection rate in school-aged children and the community population. The regression coefficients aG, bG, aI, bI, aA and bA were 0.4718, 6.8462, 0.7985, 9.6128 and 0.1619 And 4.2688. Conclusion The prevalence of Schistosoma japonicum infection among school-age children can be considered as an index to evaluate the infection rate of Schistosoma japonicum in Chinese community population.
