目的了解珠三角某市居民主要肠道寄生虫的感染现状,为今后防治措施的制订提供基础数据。方法 2015年6—9月选择该市辖区内24个镇区中的4个镇区作为抽样调查点进行肠道寄生虫感染现状调查。记录并比较不同性别、年龄、文化程度、职业调查人群肠道寄生虫感染情况。计数资料采用χ~2检验,P<0.05为差异有统计学意义。结果共收集检测1 073份粪便标本,总感染率为37.37%(401/1 073),检出两种寄生虫,其中华支睾吸虫和鞭虫的感染率分别为37.37%(401/1 073)和0.19%(2/1 073)。男性感染率为41.86%(229/547),高于女性的32.70%(172/526),差异有统计学意义(P<0.05)。不同年龄、职业、文化程度各组感染率比较差异均有统计学意义(均P<0.05)。感染者主要分布于40~60岁组。职业分布以退休人员组最高,感染率为55.56%(40/72)。文化程度以初中组最高,感染率为46.28%(143/309)。结论珠三角某市主要肠道寄生虫病已得到有效控制,但华支睾吸虫感染率仍处于较高水平,应加强健康教育及定期驱虫工作。
Objective To understand the prevalence of major intestinal parasites in residents of a city in the PRD and to provide basic data for the future prevention and control measures. Methods From June to September of 2015, 4 out of 24 townships in the district were selected as sample survey sites to investigate the status of intestinal parasites infection. Record and compare different gender, age, education level, occupational survey of intestinal parasites infection. Counting data using χ ~ 2 test, P <0.05 for the difference was statistically significant. Results A total of 1 073 stool specimens were collected and the total infection rate was 37.37% (401/1 073). Two kinds of parasites were detected. The infection rates of Clonorchis sinensis and Trichuris trichinella were 37.37% (401/1 073 ) And 0.19% (2/1 073). The prevalence rate of male was 41.86% (229/547), higher than that of female (32.70%) (172/526), the difference was statistically significant (P <0.05). The infection rates in different age groups, occupation groups and education groups were significantly different (all P <0.05). Infection are mainly distributed in the 40 to 60 age group. The occupational distribution was the highest among retirees, with an infection rate of 55.56% (40/72). The highest level of education in junior high school group, the infection rate was 46.28% (143/309). Conclusions The main intestinal parasitic disease in a certain area of the Pearl River Delta has been effectively controlled. However, the infection rate of Clonorchis sinensis is still at a high level. Health education and regular deworming work should be strengthened.
