分析山东省人体肠道蠕虫感染情况，为寄生虫防治策略和措施的制定提供科学依据。按照《全国人体重点寄生虫病监测方案》要求开展调查，选取济南、青岛、潍坊、济宁、临沂、德州、聊城、滨州、菏泽等9个地级市共14个调查点，每个调查点以地理方位划分东、南、西、北、中5个片区，每个片区选取1个街道的1个行政村开展监测，每个调查村选择3周岁以上常住居民至少200人。采用改良加藤厚涂片法（一粪两检）检查肠道蠕虫虫卵，每个调查村3~9岁儿童加做透明胶纸肛拭法检查蛲虫卵。采用SPSS21.0软件进行统计学分析，感染率的比较采用χ²检验。共调查14 507人，检出人体肠道蠕虫感染者45人，总感染率为0.31%（45/14 507），其中蛔虫、鞭虫、华支睾吸虫等3种肠道蠕虫的感染率分别为0.01%（2/14 507）、0.30%（43/14 507）、0.01%（2/14 507），蛲虫的感染率为0.82%（15/1 832）。临沂的肠道蠕虫感染率最高，为4.16%（42/1 010）；其次为济宁，感染率为0.10%（1/1 014）；青岛和潍坊的感染率均为0.05%（1/2 050，1/2 115）；4个市的感染率差异有统计学意义（χ² = 196.906，P < 0.01）。德州、聊城、滨州、菏泽的蛲虫感染率分别为0.96%（2/208）、3.00%（3/100）、1.57%（6/382）、2.78%（4/144），差异无统计学意义（χ² = 2.536，P > 0.05）。男性和女性的肠道蠕虫感染率分别为0.28%（19/6 805）、0.36%（28/7 702）；19~40岁组人群的肠道蠕虫感染率最高，为0.40%（12/2 988）（χ² = 2.837，P > 0.05）；小学和初中文化程度人群的肠道蠕虫感染率最高，均为0.41%（18/4 427，16/3 933）。不同性别、不同年龄组和不同文化程度人群的蠕虫感染率差异均无统计学意义（χ² = 0.796、2.837、5.251，P > 0.05）。职业为学生的人群肠道蠕虫感染率最高，为0.56%（11/1 970），不同职业人群肠道蠕虫感染率差异有统计学意义（χ² = 23.847，P < 0.01）。山东省人体肠道蠕虫的感染率处于较低水平，但部分地区仍存在传播风险，需继续开展监测防控工作。

To analyze the human intestinal helminth infection in Shandong Province and provide a scientific basis for developing parasite control strategies and measures. The survey was conducted according to the requirements of the National Surveillance Program for Key Human Parasitic Diseases, and 14 survey sites were selected as the investigation points in 9 cities, including Jinan, Qingdao, Weifang, Jining, Linyi, Dezhou, Liaocheng, Binzhou and Heze. Each survey point was assigned to 5 regions in the east, south, west, north and middle according to geographical orientation, and 1 administrative village from 1 neighbourhood was selected in each region for monitoring. At least 200 permanent residents over the age of 3 years were selected from each village. The modified Kato-Katz thick smear method was used to examine parasite eggs (two slide-reading for each sample). Children aged 3 to 9 years in each village were also tested with the cellophane tape anal swab method to examine Enterobius vermicularis eggs. SPSS 21.0 software was used for statistical analysis, and the difference between infection rates was compared with χ² test. A total of 14 507 people were investigated, 45 people were found to be infected with intestinal helminth, the total infection rate was 0.31% (45/14 507). The infection rates of Ascaris lumbricoides, Trichuris trichura, Clonorchis sinensis and E. vermicularis were 0.01% (2/14 507), 0.30% (43/14 507), 0.01% (2/14 507), 0.82% (15/1 832), respectively. The infection rate of intestinal helminth was the highest in Linyi City (4.16%, 42/1 010). The infection rate of Jining City was 0.10% (1/1 014). The infection rates in Qingdao and Weifang were 0.05% (1/2 050, 1/2 115). The difference was statistically significant (χ² = 196.906, P < 0.01). The rates of E. vermicularis infection in Dezhou, Liaocheng, Binzhou and Heze were 0.96% (2/208), 3.00% (3/100), 1.57% (6/382), 2.78% (4/144) respectively, with no significant difference (χ² = 2.536, P > 0.05). The infection rate of intestinal helminth was 0.28% (19/6 805) in males and 0.36% (28/7 702) in females. The infection rate of intestinal helminth in the 19-40 years old group was the highest at 0.40% (12/2 988). The infection rates of intestinal helminth were the highest in primary school and middle school education levels, both of which were 0.41% (18/4 427, 16/3 933). There were no statistically significant differences in intestinal helminth infection rate between different genders, different age groups and different educational levels (χ² = 0.796, 2.837, 5.251; P > 0.05). The highest intestinal helminth infection rate was 0.56% (11/1 970) in students, and there was a significant difference in intestinal helminth infection rate among different occupations (χ² = 23.847, P < 0.01). The infection rate of human intestinal helminth in Shandong Province is at a low level, but there is still a risk of transmission in some areas, and surveillance and prevention should be continued.
