To investigate the situation of notification and HIV antibody testing of sexual partners of people who lived with HIV, and to analyze the factors which could influence the rate of sexual partner notification of Shanghai.
HIV-positive people were recruited from Jiading, Jinan and Xuhui District in Shanghai, all of them were diagnosed with HIV from July 1, 1998 to July 30, 2014, and all of them were ≥ 16 years old, ruled out poor compliance, unwillingness to cooperate, mental disorders, deaf and other factors that could not properly answer questions. Face to face questionnaires were used to collect demographics, HIV related knowledge, testing of HIV, status of sexual partners before they have been diagnosed with HIV, notification of sexual partners. These questionnaires were self-designed. The differences of notification situation and the HIV-positive rate among different sexual partners were compared by chi-square tests. The factors which would influence the rate of sexual partner notification were analyzed by logistic regression, and the OR (95% CI) value was calculated.
A total of 307 people living with HIV were surveyed, of these 276 (89.9%) were males and 31 (10.1%) were females. The rates of different sexual partner been notified from spouses, homosexual regular partners, heterosexual regular partners, heterosexual no-regular no-commercial partners, homosexual no-regular no-commercial partners to commercial sexual partners were 68.2% (105/154), 44.7% (119/266), 21.4% (22/103), 5.8% (3/52), 5.5% (43/787), and 0.4% (1/235) (χ(2) = 5.22, P < 0.001). Among these been notified sexual partners 277 of them have had HIV antibody tested, 90 persons was HIV-positive, the rate was 32.5%. Confirmed time (OR: 0.37, 95% CI: 0.16-0.86), whether inform staff allowed the HIV-positive people mobilize their sexual partners have HIV-antibody test (OR: 9.63, 95% CI: 3.77-24.55), whether someone else was present during notification (OR: 5.57, 95% CI: 1.96-15.78) and relationship stability (OR: 28.55, 95% CI: 7.93-102.75; OR: 14.13, 95% CI: 4.87-41.02) were associated with HIV-positive people disclosing their infected status to their sexual partners.
The rate of notification to these partners was low, but the HIV antibody positive rate was high among the sexual partners in the three research districts of Shanghai. Shorter confirmed time, inform staff didn't allow the HIV-positive people mobilize their partners have HIV-antibody test, no other was present during people was told they were HIV-positive, and no fixed sexual relationship, all these could make lower rate of sexual partners to be notified.
了解上海市艾滋病病毒（HIV）感染者性伴告知及HIV抗体检测情况，分析影响性伴告知率的因素。
选取上海市嘉定区、金山区和徐汇区的HIV感染者，均为1998年7月1日至2014年7月30日确诊，年龄≥16岁，排除依从性差、不愿合作、精神障碍、聋哑等不能正确回答问题的因素。采用自行设计的面对面调查问卷收集人口学资料、HIV相关知识、HIV检测情况、确诊HIV前性伴情况、性伴告知情况。采用χ²检验比较不同性伴告知情况及HIV抗体阳性率差异。采用Logistic回归分析影响性伴告知率的因素，并计算比值比（OR）及95%可信区间（CI）。
共调查307例HIV感染者，其中男性276例（89.9%），女性31例（10.1%）。配偶、男男性行为固定性伴、异性性行为固定性伴、异性非固定非商业性伴、男男性行为非固定非商业性伴、商业性伴的性伴告知率分别为68.2%（105/154）、44.7%（119/266）、21.4%（22/103）、5.8%（3/52）、5.5%（43/787）、0.4%（1/235）（χ² = 5.22，P < 0.001）。已告知性伴中277例进行了HIV抗体检测，90例HIV抗体阳性，阳性率为32.5%。确诊时间（OR：0.37，95%CI：0.16 - 0.86）、告知时工作人员是否允许感染者动员性伴检测（OR：9.63，95%CI：3.77 - 24.55）、告知时有无他人在场（OR：5.57，95%CI：1.96 - 15.78）及关系稳定性（OR：28.55，95%CI：7.93 - 102.75；OR：14.13，95%CI：4.87 - 41.02）与感染者向性伴披露感染状况有关。
上海市3个研究区性伴告知率低，但性伴HIV抗体阳性率高。确诊时间短、告知时工作人员不允许感染者动员性伴检测、告知时无他人在场及无固定性关系可使性伴告知率降低。
