目的:调查大连市2011~2013年从业人员梅毒感染现状,探讨防控对策与措施。方法:采用环状片测试法(TRUST)进行初筛,阳性者采用梅毒螺旋体血球凝集试验(TPPA)进行确诊。采用Excel电子表格进行资料整理及SPSS13.0进行数据分析。结果:2011~2013年间共检测从业人员137046人,梅毒血清抗体阳性者252人,阳性率0.18%,从业人员梅毒不同年份显著性检验无差别(x2=1.14,P>0.05)。男性梅毒抗体阳性率0.18%(84/47693),女性0.18%(158/893534),男女感染率相同,差异无统计学意义(x2=0.0008,P>0.05)。梅毒抗体阳性者主要集中在20~49岁,占总阳性的90%(218/242)。梅毒抗体阳性率在各行业组由高到低依次为非食品2.99%、食品加工0.26%、环境卫生0.16%、食品0.13%、美容美发0.03%。梅毒抗体阳性率在各行业组之间有统计学意义(x2=1285.49,P<0.05)。结论:2011~2013年从业人员血清阳性率近三年稳定,从事非食品的青壮年为防控重点对象。
Objective: To investigate the current situation of syphilis infection among employees in Dalian from 2011 to 2013, and to explore the countermeasures and measures for prevention and control. Methods: The first screening was performed by TRUST. The positive ones were diagnosed by TPPA. Using Excel spreadsheet for data collation and SPSS13.0 for data analysis. Results: A total of 137,046 practitioners and 252 positive syphilis were detected between 2011 and 2013, with a positive rate of 0.18%. There was no significant difference in the significance of syphilis between different years (x2 = 1.14, P> 0.05). The positive rates of syphilis in males were 0.18% (84/47693) and 0.18% (158/893534) in females. There was no significant difference between males and females (x2 = 0.0008, P> 0.05). Syphilis antibodies were mainly concentrated in 20 to 49 years old, accounting for 90% of the total positive (218/242). The positive rates of syphilis antibody in various industries from high to low were non-food 2.99%, food processing 0.26%, environmental sanitation 0.16%, food 0.13% and beauty salons 0.03%. The positive rate of syphilis antibody was statistically significant among all industry groups (x2 = 1285.49, P <0.05). Conclusion: From 2011 to 2013, seropositive rate of practitioners is stable in recent three years. Young adults engaged in non-food are the key prevention and control targets.
