为了解肠寄生虫感染的影响因素，选择已进行粪管改厕的一自然村的４２１人及另一未进行粪管改厕的自然村的３８０人，对肠寄生虫感染的２５项可能影响因素，在单因素χ２分析基础上进行了非条件Ｌｏｇｉｓｔｉｃ回归分析，单因素Ｌｏｇｉｓｔｉｃ回归分析显示，ＯＲ值大于１者有水源类型、供水状况、正房面积、手抓食品习惯、农田用新鲜粪、粪便无害化处理６项因素；多元Ｌｏｇｉｓｔｉｃ回归分析表明，粪便无害化处理及手抓食品习惯是人群肠寄生虫感染的主要影响因素，其ＯＲ值分别为２．１８和６．３１。
In order to understand the influencing factors of intestinal parasitic infection, we selected 421 possible natural persons infected with intestinal parasites by infecting 421 people in a natural village with toilet-care toilets and another 380 in natural villages without toilet- Non-conditional logistic regression analysis was carried out on the basis of single factor χ2 analysis. The univariate Logistic regression analysis showed that the water source type, water supply status, area of main house, habit of grasping food, fresh manure in farmland, no manure Multivariate Logistic regression analysis showed that the harmless manure and finger food habits were the main influential factors of intestinal parasitic infection in humans, with OR values of 2.18 and 6.31 respectively.
