目的调查海南省无偿献血者梅毒感染状况。方法用ELISA法对2002～2008年海南省342 965名无偿献血者进行梅毒抗体检测,并将献血人群分为学生、现役军人组和其他职业组,采用χ2检验对梅毒抗体检测及分组结果进行统计分析。结果342 965名无偿献血者中,梅毒抗体阳性2 940例,感染率为0.86%,2002～2008年的梅毒抗体阳性率分别为1.16%、1.23%、1.15%、0.82%、0.59%、0.67%、0.64%,其中学生、现役军人献血人群梅毒抗体阳性278例,占其献血人数的0.26%,其他无偿献血人群梅毒抗体阳性2 662例,占其献血人数的1.12%。结论海南省2002～2008年无偿献血者梅毒抗体阳性率逐年下降,学生、现役军人献血人群梅毒感染率较低,χ2=633.852,P<0.05,今后可重点从学生、现役军人群体中招募血源。
Objective To investigate the status of syphilis infection in unpaid blood donors in Hainan Province. Methods The ELISA method was used to detect the syphilis antibody of 342 965 unpaid blood donors in Hainan Province during 2002-2008. The blood donors were divided into students, active servicemen and other occupational groups. The results ofχ2 test were used to test the results of syphilis antibody test and grouping analysis. Results Among 342 965 unpaid blood donors, syphilis was positive in 2 940 cases and the infection rate was 0.86%. The positive rates of syphilis antibody between 2002 and 2008 were 1.16%, 1.23%, 1.15%, 0.82%, 0.59% and 0.67%, respectively , 0.64%. Among them, 278 cases were positive for syphilis antibody in blood donated by students and active servicemen, accounting for 0.26% of the total number of blood donors, while 2 662 were positive for syphilis antibody in other blood donors, accounting for 1.12% of the donated blood. Conclusions The positive rates of syphilis antibody in voluntary blood donors decreased year by year in Hainan Province from 2002 to 2008, and the prevalence of syphilis in blood donated by students and military personnel in active service was lower (χ2 = 633.852, P <0.05). In the future, it could focus on recruiting blood from students and military service personnel .
