【摘要】：探索鄱阳湖血吸虫病典型疫区的社会、经济、环境因子与血吸虫病疫情的相互关系及其相关程度。采用经典统计学中单相关、偏相关和复相关系数研究南昌县43个行政村血吸虫病感染人数与疫水接触指数、耕牛存栏数、行政村水域面积、行政村湖边边界长度和行政村到鄱阳湖边界的距离的内在联系和相互关系。所选5个因子与感染人数的简单相关系数都达到了0.05置信水平,固定疫水分布各因子计算疫水接触各因子与"感染人数"的偏相关系数,与固定疫水接触各因子计算疫水分布各因子与"感染人数"的偏相关系数,都小于简单相关系数,说明疫水分布因子与疫水接触因子具有内在关联;"感染人数"与所有5个因子的复相关系数为0.948,达到了0.005的极显著置信水平。所选的村级宏观因子都与血吸虫病疫情显著相关。
[Abstract]:To explore the relationship and correlation between social, economic and environmental factors and schistosomiasis epidemic situation in typical endemic areas of schistosomiasis in Poyang Lake.The single correlation, partial correlation and multiple correlation coefficient were used to study the number of schistosomiasis infection in 43 administrative villages in Nanchang County and the contact index of infected water with epidemic water, the number of cultivated cattle and the area of water area of administrative village.The relationship between the length of the lake boundary and the distance between the administrative village and Poyang Lake.The simple correlation coefficient between the five factors selected and the number of infected persons reached 0.05 confidence level. The partial correlation coefficient between the factors exposed to infected water and the number of infected people was calculated by the factors of fixed epidemic water distribution.The partial correlation coefficient between the factors of epidemic water distribution and the number of infected people was less than that of simple correlation coefficient.The results showed that the distribution factor of epidemic water had an inherent correlation with the contact factor of infected water, and the multiple correlation coefficient between "number of infected persons" and all five factors was 0.948, which reached a very significant confidence level of 0.005.All the village macro factors were significantly related to schistosomiasis.
