江门市2006年不同人群HIV检测结果

目的 了解2006年江门市VCT门诊求询者、综合门诊就诊者和洗浴娱乐场所从业员HIV感染状况,为制定艾滋病预防控制策略提供科学依据.方法 对2006年本中心VCT门诊求询者、综合门诊就诊者及常规体检的洗浴娱乐场所从业员采集血液标本,首先用一种酶联试剂筛查,阳性者再用原有试剂和另一种酶联试剂重复检测,其一为阳性或两者皆阳性定义为“筛查阳性”,并应用蛋白免疫印迹(WB)法确证.结果 共检测1 072人,HIV抗体阳性26人(2.43％),男性20人(7.55％),女性6人(0.74％),性别间差异有统计学意义(P＜0.01),年龄分布40岁以上组高发(P＜0.01).VCT门诊求询者阳性率为10.23％,性别间差异无统计学意义(P＞0.05),年龄分布50岁以上组高发(P＜ 0.05).综合门诊就诊者阳性率为2.50％,性别间差异无统计学意义(P＞ 0.05),年龄分布40岁以上组高发(P＜0.05).洗浴娱乐场所从业员未检出阳性.不同人群以VCT门诊求询者阳性率最高(P＜0.01).结论 VCT门诊求询者HIV阳性率偏高,属于高度易感人群,应广泛、深入地在高危人群中开展高质量的VCT,这是今后艾滋病防控工作的重点.

Results of HIV test among different population groups in Jiangmen in 2006

Objective To investigate HIV infection status among three groups of different population in Jiangmen in 2006 and evaluate the effectiveness of HIV voluntary counseling and testing（VCT）in order to improve HIV VCT service.Methods All the serum samples from VCT visitors,polyclinic visitors and attendants working in public baths and amusement places were tested with one ELISA assay,then positive specimens were further tested with the above ELISA assay and another ELISA assay together,positive specimens in either of ELISA assays were defined＂screening positive＂and confirmed by western blot assay.Results Total infection rate of HIV were 2.43%（26/1072）,there’s significant difference（χ2= 39.02,P0.01）between male（20/26,7.55%） and female（6/26,0.74%）,and most of the infections occurred to age groups of over 40 years.The positive rate of HIV antibody among VCT visitors,polyclinic visitors and attendants working in public baths and amusement places was 10.23%,2.50% and 0%,respectively.Most cases occurred to age groups of over 50 years in VCT visitors groups（P0.05）over 40 years in polyclinic group（P0.05）,and no significant difference were found between male and female within either of group（P0.05）.Conclusion The positive rate of HIV antibody in VCT visitors group was highest among three groups in Jiangmen in 2006.The implementation of VCT is an effective way to identify HIV positive persons,which plays a fundamental role in preventing HIV∕AIDS prevention and control.
