目的了解溧阳市农村居民主要寄生虫病流行情况及相关知识、态度和行为，为制定相应的预防策略和措施提供依据。方法从3个镇选取3个村作为调查点，对在该村居住6个月以上的3岁以上居民进行调查。采用Kato-Katz技术对居民粪便中肠道寄生虫卵进行检测，采用透明纸肛门拭子对3 ~ 6岁儿童蛲虫卵进行检测。采用碘液涂片法和生理盐水涂片法检查肠道原生动物包囊或滋养体。采用管式滤纸培养法对钩虫种类进行鉴定。采用结构化调查问卷，收集居民对主要寄生虫病防治的知识、态度和实践情况。结果3个农村调查点共调查检测居民759人，仅检出2例寄生虫感染，总感染率为0.26%。两例均为轻度感染，无混合性感染。蛔虫病、滴虫病、钩虫病知识知晓率为37.9%，支睾吸虫病知识知晓率为13.8%。年龄和文化程度是影响居民寄生虫病防治知识的重要因素。饭前洗手、便后洗手、不喝生开水的形成率分别为83.8%和92.1%。11.6%的居民经常食用生的或半熟的淡水鱼虾，53.0%的居民没有使用不同砧板准备生的和熟的食物的行为。以新鲜粪便为粪肥和赤脚田间作业的比例分别为13.8%和22.8%。认为可以、不能、不确定改变寄生虫感染危险行为和习惯的比例分别为40.2%、28.5%和31.4%。结论溧阳市农村居民主要寄生虫病感染率较低，寄生虫病预防知识知晓率较低。因此，应加强寄生虫病防治的健康教育，引导他们养成良好的卫生、饮食和农耕习惯。应不断改善环境卫生，阻断寄生虫感染的流行。
OBJECTIVE To investigate the prevalence of major parasitic diseases and related knowledge, attitude and practice among rural residents in Liyang City, so as to provide the evidence for formulating appropriate preventive strategies and measures. METHODS Three villages were selected from three towns as survey sites, and the residents who were above three years old and had been in the village for over six months were investigated. The Kato-Katz technique was applied to detect intestinal parasite eggs in residents' feces, and the cellophane anal swab was used to detect Enterobius vermicularis eggs among children aged 3-6 years. The iodine liquid smear and saline smear methods were used to examine intestinal protozoa cysts or trophozoites. Hookworm species were identified by the tube filter paper culture method. A structured questionnaire was used to collect the information on residents' knowledge, attitude and practice of the prevention and control of major parasitic diseases. RESULTS Totally 759 residents were investigated and tested at the three rural survey sites, and only 2 cases were detected of parasitic infection and the total infection rate was 0.26%. Both cases were mild infections without mixed infection. The total awareness rate of knowledge on ascariasis, trichuriasis and ancylostomiasis was 37.9%, while the awareness rate of knowledge on clonorchiasis was 13.8%. The age and educational level were important factors of the knowledge on prevention and control of parasitic diseases among the residents. The formation rates of washing hands before meal and after using the toilet, and never drinking unboiled water were 83.8% and 92.1%, respectively. Totally 11.6% of the residents usually ate raw or half-cooked freshwater fishes and shrimps, and 53.0% had not the behavior to prepare raw and cooked food using the different chopping boards. The proportions of residents using fresh feces as manure and working in the field with bare feet were 13.8% and 22.8% respectively. The proportions of residents who thought they could, could not, or were not sure to change the risk behaviors and habits of parasitic infections were 40.2%, 28.5% and 31.4%, respectively. CONCLUSIONS The infection rate of major parasitic diseases among the rural residents in Liyang City is low, and the awareness rate of knowledge on preventing parasitic diseases is also low. Therefore, the health education on the prevention and control of parasitic diseases should be strengthened to guide them to develop good hygiene, diet and farming habits. The environmental sanitation should be continuously improved to block the endemic of parasitic infection.
