Abstract

Objective: To investigate the endemic situation of human Toxoplasma gondii infection in Nanchang City in 2014 and analyze the influencing factors, so as to provide the evidence for control measures.

Methods: The high-risk population of T. gondii infection in Nanchang City was collected as an experiment group, and a control group was settled with the ratio of 1∶1. The serum tests and epidemiology surveys were conducted simultaneously, and the influencing factors were analyzed.

Results: The total positive rate of human T. gondii was 5.17% (124/2 400) among the whole population in Nanchang City in 2014. The positive rate was 7.50% (90/1 200) in the experiment group and 2.18% (34/1 200) in the control group, and the difference was significant (χ2 =26.668, P<0.05). The results of univariate analysis indicated that different dietary habits and health habits were closely related to the infection of T. gondii (χ2 =16.522, 64.954, both P<0.05). The result of Logistic analysis showed that the risk factors of T. gondii infection were occupation, educational levels, raising cats, contacting animals or raw meat, and eating raw or uncooked beef.

Conclusions: The high risk population of T. gondii infection is the key population of the toxoplasmosis control. Unhealthy dietary and living habits are key influencing factors of toxoplasmosis, and the related health education and surveillance work should be strengthened.

[摘要]目的 调查2014年南昌市人群弓形虫感染现状并分析其影响因素, 为制定弓形虫病防治对策提供科学依据。方法 选择南昌市弓形虫病高危人群为实验组, 1∶1同比选取普通人群作为对照组, 同时进行血清学检测和流行病学调 查, 分析其影响因素。结果 南昌市人群弓形虫总感染率为5.17% (124/2 400) 。9类高危人群总感染率 (7.50%, 90/1 200) 高于普通人群 (2.83%, 34/1 200), 差异有统计学意义 (χ2 =26.668, P<0.05) 。单因素分析结果显示, 不同饮食习惯 和卫生习惯与弓形虫感染密切相关 (χ2 =16.522、64.954, P 均<0.05) 。多因素Logistic 回归分析结果显示, 职业、文化程 度、养猫、接触动物或肉制品、生吃或半生吃牛肉是人群弓形虫感染的危险因素。结论 南昌市弓形虫感染高危人群是 弓形虫病防治的重点人群。不良饮食及卫生习惯是弓形虫感染的重要影响因素, 应加大弓形虫病防治相关知识宣传力 度, 加强对重点人群的监测力度。.
