BACKGROUND Mother to child transmission is responsible for 90% of child infection with human immune deficiency virus (HIV). Dual contraceptive use is one of the best actions to prevent mother's human immune deficiency virus transmission to her child and partner. This study aimed at assessing the prevalence and factors associated with dual contraceptive use among sexually active women on antiretroviral therapy in Gondar City, northwest, Ethiopia. METHODS An institution based cross sectional study was conducted in Gondar City public health facilities from December 1 to 31, 2018. Systematic random sampling technique was utilized to include 563 study participants. Data were collected by interview using a structured questionnaire. Descriptive analysis was made to compute mean, median and proportion. Finally, multivariable logistic regression model was fitted to identify the factors associated with dual contraceptive method utilization. Analysis was performed by using Statistical Package for Social Sciences (SPSS) software version 20. RESULTS The overall prevalence of dual contraceptive method utilization among sexually active women on antiretroviral therapy was 28.8% (95% CI: 24.9, 32.7). Women aged 35-49 years (Adjusted odds ratio (AOR): 6.99; 95% CI: 3.11, 15.71)), who lived in urban areas (AOR: 4.81; 95% CI: 2.04, 11.31), attended secondary and above education (AOR: 4.43; 95% CI: 1.92, 10.22), and disclosed HIV status to sexual partners (AOR: 9.84; 95% CI: 3.48, 27.81) were more likely to use dual contraceptive method. CONCLUSION In this study, the proportion of women who utilized dual contraceptive method was low. Age, place of residence, educational status and disclosure of HIV status were factors associated with dual contraceptive use. Therefore, providing education about the advantages of disclosing HIV status to sexual partners and strengthening of counseling about the advantages of dual contraceptive use will be helpful in enhancing the use of dual contraceptive method among sexually active women on antiretroviral therapy.

埃塞俄比亚西北部贡德尔市接受抗逆转录病毒治疗的性活跃女性的双重避孕方法使用情况及相关因素：一项横断面研究。

背景技术 90%的儿童感染人类免疫缺陷病毒（HIV）是由母婴传播造成的。使用双重避孕药是防止母亲的人类免疫缺陷病毒传播给孩子和伴侣的最佳措施之一。本研究旨在评估埃塞俄比亚西北部贡德尔市接受抗逆转录病毒治疗的性活跃女性的双重避孕药具使用率和相关因素。方法 2018 年 12 月 1 日至 31 日，在贡德尔市公共卫生机构进行了一项基于机构的横断面研究。采用系统随机抽样技术，纳入了 563 名研究参与者。使用结构化调查问卷通过访谈收集数据。进行描述性分析以计算平均值、中位数和比例。最后，拟合多变量逻辑回归模型来确定与双重避孕方法使用相关的因素。使用社会科学统计软件包 (SPSS) 软件版本 20 进行分析。 结果 在接受抗逆转录病毒治疗的性活跃女性中，双重避孕方法的总体使用率为 28.8%（95% CI：24.9，32.7）。居住在城市地区（AOR：4.81；95% CI：2.04，11.31）的 35-49 岁女性（调整后优势比 (AOR)：6.99；95% CI：3.11，15.71））接受过中等及以上教育(AOR: 4.43; 95% CI: 1.92, 10.22) 和向性伴侣披露 HIV 状况 (AOR: 9.84; 95% CI: 3.48, 27.81) 更有可能使用双重避孕方法。结论 本研究中，采用双重避孕方法的女性比例较低。年龄、居住地、教育状况和艾滋病毒感染状况的披露是与双重避孕药具使用相关的因素。因此，开展有关向性伴侣披露艾滋病毒感染状况的好处的教育，并加强对使用双重避孕药具的好处的咨询，将有助于提高性活跃妇女在抗逆转录病毒治疗中使用双重避孕药具的情况。
