四川省羊肉餐馆从业人员布鲁氏菌病血清流行病学及知晓率调查

Investigation of seroepidemiology and awareness of brucellosis in mutton restaurant employees in Sichuan

  • 摘要:
      目的  为了解四川省羊肉餐馆从业人员布鲁氏菌病(布病)感染情况及防控知识掌握情况,评估四川省职业人群布病监测可靠性,进而为布病防控策略提供依据。
      方法  选择四川省常年销售羊肉汤的区/县作为重点调查地区,对羊肉餐馆从业人员感染率及防控知识知晓情况开展横断面调查。 采用现场采样及问卷调查方式,并对所有参与问卷调查的对象采集静脉血并进行布鲁氏菌抗体检测。
      结果  在四川省自贡市、凉山彝族自治州、内江市、泸州市、成都市的145家餐馆完成问卷调查362份,采集血清样本362份。检测出布病抗体阳性血清8份,滴度最高1∶400,分布在成都、自贡、内江市,平均阳性率为2.21%。 血凝阳性者均无布病相关临床表现。 知晓率调查中85.64%的被调查者从未听说过布病。 防护措施调查中加工过程从不戴口罩的被调查者占46.69%;从不戴手套的占55.52%。 从业年限>5年感染布病风险增加(χ2=7.29,P<0.05)。 防控知识知晓程度与文化程度有关;各市/州知晓率之间存在差异,成都市布病知晓率高于其他市/州(χ2=51.70,P<0.05)。
      结论  目前,四川省布病监测点代表性不足,职业人群监测应该将羊肉餐馆从业人员纳入监测范围; 餐饮从业人员布病宣传教育工作亟待加强。

     

    Abstract:
      Objective   To understand the prevalence and awareness of brucellosis in mutton restaurant employees in Sichuan province, evaluate the reliability of brucellosis surveillance in local occupational population, and provide evidence for the prevention and control of brucellosis.
      Methods   The cross sectional investigation was conducted in the counties or districts where mutton restaurants provide services all the year round in Sichuan in forms of field sampling and questionnaire survey. Venous blood sample was collected from each survey subject for Brucella antibody detection.
      Results   A total of 362 questionnaires were completed and 362 blood samples were collected from the employees in 145 restaurants in 6 counties or districts of Zigong, Liangshan, Neijiang, Luzhou and Chengdu in Sichuan. Eight positive serum samples with the highest titer of 1:400 were detected in Chengdu, Zigong and Neijiang. The average positive rate was 2.21%. All the sero positive employees had no brucellosis related clinical manifestations. In the awareness survey, 85.64% of the employees had never heard of brucellosis. In terms of protective measures, 46.69% of the employees never wore masks during processing, 55.52% never wear gloves. The risk for brucellosis was higher in those who had worked in mutton restaurants for more than 5 years (χ2=7.29, P<0.05). The awareness rate of brucellosis prevention and control related knowledge was associated with the level of education; The awareness rate of brucellosis was higher in Chengdu than in other areas, the differences in awareness rate were significant among different areas (χ2=51.70, P<0.05).
      Conclusion   At present, the representativeness of brucellosis surveillance sites in Sichuan is not so good, so the mutton restaurant employees should be included in the surveillance of occupational population. The health education about brucellosis in catering workers needs to be strengthened.
