Abstract: Objective Objective To understand the infection status of intestinal parasites and related knowledge and behavior factors of the residents in north?west Shandong Province，so as to provide the evidence for taking targeted preventive measures. Meth Meth? ? ods ods Eighteen villages were randomly selected as survey spots by the stratified multi?stage sample method. The Kato?Katz tech? nique was used to detect intestinal parasite eggs among the residents and the cellophane tape anus test was used to detect Entero? bius vermicularis eggs among 3-12 years old children. Questionnaires were applied to investigate related knowledge and behavior factors about the intestinal parasite infections in the residents. Results Results Totally 6 366 residents were detected for intestinal para? sites and the infection rate was 0.28%（18 cases） . Totally 895 children were detected for E. vermicularis and the infection rate was 5.70%（51 cases） . Totally 2 915 residents were investigated by questionnaires and the awareness rate of knowledge about preventing parasitic diseases was 26.72%. The formation rates of washing hands before meal and after WC，washing fruit and vegetable before eating，never drinking unboiled water were 55.42%，42.87%，43.54% and 83.04% respectively. The aware? ness rate of knowledge about preventing parasitic diseases of 3-12 years old children was 12.24%；and the formation rates of washing hands before meal and after WC were 47.04% and 30.44% respectively. Conclusions Conclusions The total infection rate of intesti? nal parasites is low but the E. vermicularis infection rate is high among children in north?west Shandong Province. The awareness rate of knowledge about preventing parasitic diseases and the formation rates of healthy behaviors are all low. Therefore，the tar? geted health education should be taken to increase the awareness rate and guide the residents to develop their healthy behaviors.

摘要： 目的 目的 了解鲁西北地区居民肠道寄生虫感染情况及相关认知状况， 为采取有针对性的防治措施提供科学依 据。 方法 方法 以分层多阶段抽样法从济南、 德州、 聊城等3市随机抽取18个村作为调查点。采用改良加藤厚涂片法 （Kato? Katz） 检测调查点内居民肠道寄生虫感染情况， 并采用透明胶纸肛拭法检测3～12岁儿童蛲虫感染情况。采用问卷调查 居民肠道寄生虫感染相关认知行为因素状况。 结果 结果 Kato?Katz共检测6 366人， 总感染率为0.28% （18例）。透明胶纸 肛拭法共检测3～12岁儿童895人， 感染率为5.70% （51例）。共入户调查2 915人， 居民寄生虫病防治知识知晓率为 26.72%； 饭前洗手、 便后洗手、 生吃瓜果蔬菜洗净、 不喝生水等4种卫生行为形成率分别为55.42%、 42.87%、 43.54%、 83.04%。3～12岁儿童寄生虫病防治知识知晓率为12.24%； 饭前、 便后洗手行为形成率分别为47.04%、 30.44%。 结论 结论 鲁西北地区居民肠道寄生虫感染率较低， 而儿童蛲虫感染率较高。居民寄生虫病防治知识知晓率和卫生行为形成率较 低。应采取有针对性的健康教育提高居民肠道寄生虫病防治知识知晓率， 引导居民养成良好的卫生行为习惯。
