To study the gender-based factors which influence the condom use among the HIV serodiscordant couples in selected regions of China.
Based on the analysis of the existing case reporting database and convenient sampling in the cross-sectional study, a total of 481 female HIV-negative spouses completed an interviewer-administered questionnaire regarding demographic characters, the knowledge, behaviors and the gender-based factors in five sites of four provinces Sichuan (Zhaojue), Yunnan (Dali), Henan (Weishi) and Guangxi (Lingshan and Luzhai), during June-September 2011. χ(2) analysis and logistic regression were used to study the gender-based factors influencing condom use among the participants.
Among the 481 female HIV-negative spouses, the average age was (35.1 ± 6.7) years, and the proportion of Han and Yi nationality were high, 43.5% (209/481) and 41.8% (201/481), respectively. The awareness of knowledge related to HIV spousal transmission was high (≥ 79.6%). A total of 86.9% (418/481) used condom more frequently after informed the status of HIV infection of their spouses, and the condom use consistency was 56.6% (272/481). A total of 57.6% (277/481) reported low sexual relationship power; 34.5% (166/481) experienced forced sex in the past 1 year. And the proportion of condom use self-efficacy from 0 to 3 scores were 12.7% (61/481), 23.9% (115/481), 8.7% (42/481) and 54.7% (263/481), respectively (median = 3). Han and other nationality were significantly more likely to use condom consistently than Yi, with odds ratio (95%CI) of 0.01 (0.00 - 0.03) and 0.01 (0.00 - 0.04), and the female spouses with higher condom use self-efficacy used condom more consistently than the lower ones, with odds ratio (95%CI) of 0.20(0.11 - 0.34).
The female spouses with higher condom use self-efficacy were more likely to use condom consistently after excluding the confounding effect of nationality.
研究影响中国部分地区HIV血清学不一致夫妻使用避孕套的性别相关因素。
基于现有病例报告数据库分析及横断面研究中的便利抽样，2011年6月至9月期间，共有481名HIV阴性的女性配偶在四川（昭觉）、云南（大理）、河南（尉氏）和广西（灵山和鹿寨）四省的五个地点完成了一份由访谈员进行的问卷调查，内容涉及人口统计学特征、知识、行为及性别相关因素。采用χ(2)分析和逻辑回归研究影响参与者使用避孕套的性别相关因素。
在481名HIV阴性的女性配偶中，平均年龄为（35.1±6.7）岁，汉族和彝族比例较高，分别为43.5%（209/481）和41.8%（201/481）。对HIV配偶传播相关知识的知晓率较高（≥79.6%）。共有86.9%（418/481）的人在知晓配偶感染HIV状况后更频繁地使用避孕套，避孕套使用一致性为56.6%（272/481）。共有57.6%（277/481）的人报告性关系权力较低；34.5%（166/481）的人在过去1年中经历过强迫性行为。避孕套使用自我效能得分为0至3分的比例分别为12.7%（61/481）、23.9%（115/481）、8.7%（42/481）和54.7%（263/481）（中位数=3）。汉族和其他民族比彝族更有可能持续使用避孕套，比值比（95%CI）分别为0.01（0.00 - 0.03）和0.01（0.00 - 0.04），避孕套使用自我效能较高的女性配偶比自我效能较低的女性配偶更持续地使用避孕套，比值比（95%CI）为0.20（0.11 - 0.34）。
在排除民族混杂效应后，避孕套使用自我效能较高的女性配偶更有可能持续使用避孕套。
