摘要： 目的 调查四川省重要食源性寄生虫人群感染现状，为优化防控措施提供依据。方法 2020—2024年在四川省选取2个固定监测点，根据生态区、民族构成和经济水平采用分层多阶段随机抽样方法每年选取不少于13个流动监测点。每年按地理方位将各监测点划分为东、西、南、北、中5个片区，每个片区随机调查3周岁及以上常住人口不少于200人，采用改良加藤厚涂片法（一粪二检）检测人群食源性寄生虫感染情况。结果 共调查101 831人，检出427例感染者，总感染率为0.42%；其中412例感染带绦虫，9例感染缩小膜壳绦虫，6例感染华支睾吸虫，未发现混合感染。历年总感染率总体呈上升趋势（χ2趋势=51.830，P<0.01），由2020年的0.33%上升至2024年的0.55%。地区分布上，阿坝藏族羌族自治州总感染率最高（2.76%，228/8 264），其次为甘孜藏族自治州（1.81%，163/9 020）；不同市（州）差异有统计学意义（χ2=1 798.623，P<0.01）。男性、女性的总感染率分别为0.42%（204/48 016）和0.41%（223/53 815），差异无统计学意义（χ2=0.067，P>0.05）。20～29岁年龄组（1.03%，69/6 691）、牧民（3.27%，67/2 048）、藏族（3.21%，390/12 138）和小学及以下文化程度者（0.71%，394/55 724）的总感染率较高，总感染率在不同年龄、职业、民族和文化程度人群中的差异均有统计学意义（χ2=167.622、481.554、2 594.768、245.903，P均<0.01）。结论 四川省西部牧区的食源性寄生虫感染率较高，以带绦虫为主。为控制带绦虫病流行，需开展针对性健康教育、改进畜牧业管理，并对高危人群定期进行集体驱虫。

Abstract: Objective To investigate the prevalence status of major food-borne parasitic infections in Sichuan Province for evidence to optimize the prevention and control strategies. Methods From 2020 to 2024, two fixed monitoring sites were initially selected in Sichuan Province. Additionally, no fewer than 13 mobile monitoring sites will be chosen using a stratified multi-stage random sampling method based on ecological zones, ethnic composition, and economic levels. All monitoring sites were divided into 5 regions (east, west, south, north and central) according to their geographical locations. In each region, a random survey was conducted on no fewer than 200 permanent residents aged 3 and above. The modified Kato-Katz thick smear (two slides for one stool sample) was used to detect the food-borne parasitic infections in the population. Results A total of 101 831 subjects were surveyed, in whom 427 infections were identified, with an overall infection rate being 0.42%. Of these infected cases, 412 were positive for Taenia spp., 9 for Hymenolepis diminuta, and 6 for Clonorchis sinensis. No mixed infections were detected. The annual overall infection rate showed a significant upward trend (χ2trend=51.830, P<0.01), rising from 0.33% in 2020 to 0.55% in 2024. By regional distribution, Aba Tibetan and Qiang Autonomous Prefecture had the highest overall infection rate (2.76%, 228/8 264), followed by Ganzi Tibetan Autonomous Prefecture (1.81%, 163/9 020). The infection rate was significantly different among different cities (prefectures) (χ2=1 798.623, P<0.01). The overall infection rate was 0.42% (204/48 016) for males and 0.41% (223/53 815) for females, with no statistical difference (χ2=0.067, P>0.05). Higher overall infection rates were seen in the population aged 20-29 years (1.03%, 69/6 691), herdsmen (3.27%, 67/2 048), Tibetan ethnicity (3.21%, 390/12 138), and individuals with primary school education or below (0.71%, 394/55 724). Significant differences in overall infection rates were observed across different age groups, occupations, ethnicities, and education levels (χ2=167.622, 481.554, 2 594.768, 245.903; all P<0.01). Conclusion The western pastoral areas of Sichuan Province have a relatively high prevalence of food-borne parasitic infections, and the infection is primarily associated with Taenia. In order to control the prevalence of taeniasis, it is necessary to carry out targeted health education, improve management of the livestock husbandry, and implement regular collective deworming for high-risk populations.
