2010—2012年承德市食品和公共场所从业人员梅毒的流行病学调查

目的了解承德市食品与公共场所从业人员梅毒的感染状况及与传播有关的高危因素,评估采取相关干预措施后的效果,为进一步开展该人群的健康教育和行为干预提供依据。方法采用免疫学方法对2010年1月—2012年12月在承德市疾病预防控制中心体检科检查的从业人员进行梅毒检测,并对收集的数据进行统计分析。结果 2010—2012年共检查从业人员37 631例,检测出梅毒阳性者101例,检出率为0.268%;其中显性梅毒27例,隐性梅毒74例;梅毒阳性率呈逐年下降趋势,但差异无统计学意义（χ2=0.055,P〉0.05）;隐性梅毒检出率呈逐年上升趋势,差异有统计学意义（χ2=4.787,P〈0.05）;性别分布中男45人,女56人,性别间感染率差异无统计学意义（χ2=0.006 04,P〉0.05）。在梅毒感染阳性人员中,男性的隐性梅毒多于女性,其3年构成比差异有统计学意义（χ2=5.177,P〈0.05）;梅毒阳性患者主要分布在18~40岁性活跃年龄段及低学历人群,差异有统计学意义（χ2=10.269;χ2=6.328;P〈0.05）。结论承德市从业人员梅毒感染率呈下降趋势,说明加强公共场所人员综合干预对梅毒的控制至关重要。隐性梅毒在梅毒分类中占有较大比例,且逐年上升,今后工作重点注意自知患有梅毒者的漏检和隐性梅毒的筛查,且选用敏感性高和特异性强的试剂。

Epidemiological investigation of syphilis among employees in food industry and public places in Chengde City from 2010-2012

[Objective]To understand the situation of syphilis infection among employees in food industry and public places in Chengde City,learn about the risk factors related to the spread of syphilis,evaluate the effect of the intervention measures,and provide the basis for carrying out the health education and behavior intervention in this population. [Methods]The syphilis detection was performed among employees who have received the physical examination in Chengde Center for Disease Control and Prevention from January 2010 to December 2012,and the data were statistically analyzed.[Results]A total of 37 631 employees were detected during 2010-2012,and 101 were positive for syphilis with a positive rate of 0. 268%,which included 27 cases of dominant syphilis and 74 case of latent syphilis. The annual positive rate of syphilis decreased gradually,but the difference was not statistically significant（ χ2= 0. 055,P 0. 05）. The detection rate of latent syphilis increased year by year,and the difference was statistically significant（ χ2= 4. 787,P 0. 05）. There were 45 male patients and 56 female patients,and there was no statistically significant difference in the infection rate between males and females（ χ2= 0. 006 04,P 0. 05）. The number of latent syphilis in males was greater than that in females,and the difference in the constituent ratio was statistically significant（ χ2= 5. 177,P 0. 05）. The patients with syphilis were mainly people aged 18-40 years old,who were in the sexual activity period,and people with low educational level,while the differences were statistically significant（ χ2= 10. 269,χ2= 6. 328,P 0. 05）.[Conclusion]The infection rate of syphilis shows a descending trend among employees in food industry and public places in Chengde City,which indicates that the comprehensive intervention among employees in public places plays an important role in syphilis prevention and control. As for the syphilis classification,the latent syphilis accounts for greater proportion,and it is increasing gr
