摘要: 目的 评估河南省曼氏裂头蚴病流行区人群感染风险,并对人群曼氏裂头蚴病知识、信念、行为(知信行)情况进行调查,为制定科学的曼氏裂头蚴病防控措施提供依据。方法 2023年7—8月选择河南省周口市扶沟县秦岭村、漯河市郾城区八里村、濮阳市濮阳县杜寨村和信阳市罗山县陡山村为调查点。每个调查点在坑塘或溪流等环境采集蛙类40只以上,检测其裂头蚴感染情况;采用整群抽样法在每个调查点抽取不少于150人作为调查对象,采集其血清进行曼氏裂头蚴IgG抗体检测,同时开展知信行问卷调查,并对知信行合格率、正确率和得分进行统计分析。结果 2023年在4个调查点共采集蛙类229只,裂头蚴感染总阳性率为4.37%(10/229),其中野生蛙类阳性率为7.75%(10/129),养殖蛙阳性率为0。在4个调查点共对649人开展问卷调查,收集血清649份,人群曼氏裂头蚴IgG抗体阳性率为0.15%(1/649),人群知信行总合格率为23.73%(154/649)。不同年龄([χ2] = 30.905,P = 0.000)、文化程度人群([χ2] = 41.011,P = 0.000)知信行合格率差异具有统计学意义,合格率随年龄升高而降低([χ2]趋势 = 22.717,P = 0.000),随文化程度增高而上升([χ2]趋势 = 40.025,P = 0.000)。不同职业人群知信行合格率差异有统计学意义([χ2] = 10.721,P = 0.005)。调查人群曼氏裂头蚴病知识正确率为40.81%(2 119/5 192),信念正确率为96.66%(1 882/1 947),行为正确率为63.81%(3 727/5 841),差异有统计学意义([χ2] = 1913.73,P = 0.000),不同调查点人群曼氏裂头蚴病知识正确率([χ2] = 136.872,P = 0.000)、信念正确率([χ2] =42.347,P = 0.000)和行为正确率([χ2] = 255.157,P = 0.000)差异均有统计学意义;其中漯河市郾城区人群知识正确率和行为正确率均最高(P均< 0.05),分别为51.94%(748/1 440)和75.86%(1 229/1 620);濮阳市濮阳县人群态度正确率最高(P < 0.05),为99.11%(446/450)。结论 河南省曼氏裂头蚴病传播风险仍较高,人群对该病知晓程度较低,需进一步加强健康教育力度,提高人群对该病的知信行水平。

Abstract: Objective To assess the risk of human Spirometra mansoni infections and investigate the knowledge, attitude and practice (KAP) towards sparganosis mansoni among residents in Henan Province, so as to provide insights into formulation of the sparganosis mansoni control measures. Methods Qinling Village in Fugou County of Zhoukou City, Bali Village in Yancheng District of Luohe City, Duzhai Village in Puyang County of Puyang City and Doushan Village in Luoshan County of Xinyang City were sampled as survey sites in Henan Province from July to August 2023, and more than 40 frogs were sampled from ponds or streams in each survey site for detection of Sparganum mansoni infections. At least 150 residents were sampled using a cluster sampling method from each survey site, and the sero⁃prevalence of anti⁃S. mansoni IgG antibody was estimated. In addition, a questionnaire survey was conducted on the KAP towards sparganosis mansoni among participants, and the proportion of eligible KAP, rate of correct KAP and KAP scores were calculated.  Results A total 229 frogs were collected from 4 survey sites in 2023, and the overall prevalence of S. mansoni infection was 4.37% (10/229) in frogs, with 7.75% (10/129) prevalence in wild frogs and 0 in farm⁃bred frogs. A questionnaire survey was performed among 649 residents sampled from 4 survey sites, and 649 serum samples were collected. The sero⁃prevalence of anti⁃S.mansoni IgG antibody was 0.15% (1/649) and the overall proportion of eligible KAP was 23.73% (154/649) among participants. There were age⁃ ([χ2]  = 30.905, P = 0.000), educational level⁃ ([χ2] = 41.011, P = 0.000), and occupation⁃specific proportions of eligible KAP among participants ([χ2] = 10.721, P = 0.005), and the proportion of eligible KAP decreased with age ([χ2] trend = 22.717, P = 0.000) and increased with education levels ([χ2] trend = 40.025, P = 0.000). The rates of correct KAP towards sparganosis mansoni were 40.81% (2 119/5 192), 96.66% (1 882/1 947) and 63.81% (3 727/5 841) ([χ2] = 1 913.731, P = 0.000) among residents, respectively. The rates of correct KAP towards sparganosis mansoni varied significantly among survey sites ([χ2] = 136.872, 42.347 and 255.157; all P values= 0.000, with the highest rate of correct knowledge (51.94%, 748/1 440) and practices (75.86%, 1 229/1 620) in Yancheng District of Luohe City and the highest rate of correct attitudes in Puyang County of Puyang City (99.11%, 446/450) (all P values< 0.05).  Conclusions There is still a high transmission risk of sparganosis mansoni in Henan Province, and the KAP towards sparganosis mansoni is required to be improved among residents.
