目的调查靖江市居民肠道线虫感染情况及对其认知现状,探索有效控制肠道线虫病的措施。方法在靖江市随机抽取流动人口相对集中的乡镇,以Kato-Katz法检查居民肠道线虫病感染情况,问卷调查防病知识知晓率和卫生行为正确率。结果 2013-2015年共计在靖江市分别调查本地居民和流动人口4 555人和2 278人。本地居民肠道线虫病感染率为0.29%(13例),流动人口为0.75%(17例),差异有统计学意义(χ~2=7.380,P<0.01)。本地居民和流动人口性别间肠道线虫病感染率差异均无统计学意义(χ~2=0.010、0.048,P均>0.05)。本地居民对肠道线虫病的知晓率高于流动人口,差异有统计学意义(χ~2=9.649~164.533,P均<0.01)。结论流动人口是靖江市肠道线虫病的重点防控对象,应对其加强综合干预;健康教育中应加强钩虫病防治相关知识的宣传。
Objective To investigate the status of intestinal nematode infection in Jingjiang residents and their cognition status and to explore the effective measures to control intestinal nematode disease. Methods We randomly selected villages and towns with relatively concentrated floating population in Jingjiang. Kato-Katz method was used to examine the intestinal nematode infection among residents. The awareness rate of disease prevention knowledge and the correct rate of hygiene behavior were surveyed. Results A total of 4 555 local residents and 2 278 local residents and floating population were surveyed in Jingjiang City during 2013-2015. The infection rate of gonococcal nematodes among local residents was 0.29% (13 cases), the floating population was 0.75% (17 cases), the difference was statistically significant (χ ~ 2 = 7.380, P <0.01). There was no significant difference in the infection rates of gut nematodes among the local residents and floating population (χ ~ 2 = 0.010,0.048, P> 0.05). The rate of awareness of gut nematode by local residents was higher than that of floating population (χ ~ 2 = 9.649-164.533, P <0.01). Conclusion Floating population is the key prevention and control object of intestinal nematode disease in Jingjiang City, so it is necessary to strengthen the comprehensive intervention. In health education, the publicity of knowledge about prevention and control of hookworm should be strengthened.
