目的分析东莞市无偿献血人群梅毒感染情况,完善低危血源招募的标准,从而预防和控制经输血感染梅毒的风险,并减少因梅毒而导致的血液报废。方法对2008-2013年东莞市436 685人次无偿献血者的血液梅毒抗体检测结果进行回顾性总结分析,分析献血人群梅毒感染状况和流行病学特征。结果 2008-2013年期间,东莞市无偿献血人群梅毒感染率分别为0.67%、0.55%、0.62%、0.58%、0.67%、0.69%,总感染率为0.63%,不同年度间梅毒感染率有波动,其差异有统计学意义(P<0.05);不同年龄组献血者中36~岁组梅毒感染率最高,为1.05%,18~岁组感染率最低,为0.35%,差异有统计学意义(P<0.05);女性献血者梅毒感染率为0.69%,高于男性献血者梅毒感染率0.61%,差异有统计学意义(P<0.05);学历越低的献血者梅毒感染率越高,差异有统计学意义(P<0.05)。结论梅毒在东莞市无偿献血人群中一直维持较高水平的流行状态,不同年龄、性别和学历的献血者梅毒感染率有差异。
Objective To analyze the prevalence of syphilis infection in blood donors in Dongguan and to improve the criteria for recruitment of low-risk blood donors so as to prevent and control the risk of syphilis infection through blood transfusions and to reduce blood waste due to syphilis. Methods The blood syphilis antibody test results of 436 685 volunteers from Dongguan in 2008-2013 were retrospectively analyzed to analyze the prevalence and epidemiological characteristics of syphilis among blood donors. Results During 2008-2013, the prevalences of syphilis in unpaid blood donors in Dongguan were 0.67%, 0.55%, 0.62%, 0.58%, 0.67% and 0.69%, respectively. The total infection rate was 0.63% , The difference was statistically significant (P <0.05). Among the blood donors of different age groups, the highest syphilis infection rate was 1.05% in the 36 ~ year group and the lowest in the 18 ~ year group was 0.35%, the difference was statistically significant P <0.05). The syphilis infection rate in female blood donors was 0.69%, which was higher than that of male blood donors (0.61%), the difference was statistically significant (P <0.05). The lower the education level, the higher the syphilis infection rate was. There was statistical significance (P <0.05). Conclusion Syphilis has maintained a high prevalence in blood donors in Dongguan City. Syphilis infection rates among blood donors of different age, sex and educational level are different.
