To investigate contraceptive use among HIV-positive women in Ha long city and Cam Pha town of Quang Ninh, a Northern province of Vietnam.
Cross-sectional questionnaire study among HIV-positive women identified through the district HIV/AIDS register. Information on socioeconomic characteristics and contraceptive use before and after HIV diagnosis was obtained through structured questionnaires. Chi-square testing was used to assess whether the included women differed from the target population in terms of age. Crude Odds ratios (ORs) were calculated to show the association between contraceptive use and the women's socioeconomic characteristics. Logistic regression analyses were applied to adjust for possible confounding. The women's contraceptive use before HIV testing and after HIV testing was described and compared by Chi-square testing, and the association between post-test counselling and the women's use of condom was assessed by ORs.
Of the 351 participants, 63% stated they had used contraception before HIV diagnosis and 89% stated they had used contraception after HIV diagnosis. Forty six per cent of the women had been using either the pill or an intrauterine device (IUD) before the diagnosis whereas the same applied for only 8% of the women after diagnosis. Thirty-nine per cent stated they had been using condom before HIV diagnosis whereas 87% stated condom use after HIV diagnosis. Condom use was more common among women who had received post-test counselling (OR 3.03, 95% CI 1.03-8.90).
A change of contraceptive methods from IUD and oral contraception before HIV diagnosis to condom use after HIV diagnosis was observed. The women's use of condoms after HIV diagnosis was associated with having received post-test counselling.
调查越南北部广宁省下龙市和锦普镇 HIV 阳性妇女的避孕措施使用情况。
通过地区艾滋病毒/艾滋病登记册确定 HIV 阳性妇女，对其进行横断面问卷调查。通过结构式问卷获取与社会经济特征和 HIV 诊断前后避孕措施使用情况相关的信息。采用卡方检验评估纳入的妇女在年龄方面与目标人群是否存在差异。计算粗比值比（OR）以显示避孕措施使用情况与妇女社会经济特征之间的关联。应用逻辑回归分析调整可能存在的混杂因素。通过卡方检验对 HIV 检测前和 HIV 检测后妇女的避孕措施使用情况进行描述和比较，并通过 OR 评估检测后咨询与妇女使用避孕套之间的关系。
在 351 名参与者中，63%的妇女表示在 HIV 诊断前使用过避孕措施，89%的妇女表示在 HIV 诊断后使用过避孕措施。46%的妇女在诊断前使用过避孕药或宫内节育器（IUD），而同样的情况在诊断后仅适用于 8%的妇女。39%的妇女表示在 HIV 诊断前使用过避孕套，而 87%的妇女在 HIV 诊断后使用过避孕套。接受检测后咨询的妇女使用避孕套的情况更为常见（OR 3.03，95%CI 1.03-8.90）。
观察到 HIV 诊断前避孕方法从 IUD 和口服避孕药转为 HIV 诊断后使用避孕套。妇女在 HIV 诊断后使用避孕套与接受检测后咨询有关。
