河南省某地区配偶间HIV性传播状况调查

Epidemiological analysis of HIV infections via sexual transmission between spouses in an area of Henan province

目的:了解河南省某地区配偶间HIV性传播状况,为预防控制艾滋病配偶间性传播提供科学依据。方法:2006年1月1日至2009年12月31日对河南省某地区2651个HIV单阳家庭进行随访检测,分别在每年度的6月底和12月底对感染者配偶用酶联免疫吸附试验和免疫印迹试验进行一次HIV抗体检测。结果:共对2445个家庭完成随访调查,随访率为92.2%,配偶间HIV传播73对,累计性传播率2.98%。由丈夫传染给妻子44对(传播率4.33%),由妻子传染给丈夫29对(传播率2.03%)。丈夫年龄在30～39岁的家庭性传播率为55.8%(23/348)高于40岁以上年龄组(0.6%,1/1053)。结论:河南某地区建立随访关系的配偶间HIV性传播率较先前明显降低,但需要进一步加大预防配偶间HIV性传播工作的力度,最大限度避免HIV配偶间传播。

Aim：To study the epidemiological status of HIV infection between married couples.Methods：A total of 2 651 couples with only one confirmed HIV-positive spouse were followed up from 2006 to the end of 2009.HIV antibody was detected every six months by ELISA and Western blot.Results：2 445 couples finished the follow-up,and the follow-up rate was 92.2%.73 couples had sexual transmission,and the cumulative sexual transmission rate was 2.98%.The sexual transmission rate was 4.33%（44/1 015）from the male to the female and 2.03%（29/1 430）from the female to the male.Conclusion：The frequencies of sexual transmission in Henan province is relatively low.The publicizing should be strengthened in single HIV positive families to maximally avoid sexual transmission between spouses.
