The cooccurrence of HIV and unintended pregnancy has prompted a body of work on dual protection, the simultaneous protection against HIV and unintended pregnancy. This study examines dual protection and dual methods as a risk-reduction strategy for women living with HIV. Data are from a cross-sectional sample of HIV-positive women attended in Specialized STI/AIDS Public Health Service Clinics in 13 municipalities from all five regions of Brazil 2003-2004 (N = 834). Descriptive techniques and logistic regression were used to examine dual protection among women living with HIV. We expand the definition of dual protection to include consistent condom use and reversible/irreversible contraceptive methods, we test the dual methods hypothesis that women who use dual methods will use condoms less consistently than women who use only condoms, and we identify predictors of dual protection. Dual protection is common in our sample. Women who use dual methods have lower odds of consistent condom use than women who only use condoms. Among dual method users, we find that women who use an irreversible method use condoms more consistently than women who use a reversible method. Women on ART and with an HIV-serodiscordant partner have greater odds of consistent condom use than their counterparts.
艾滋病毒与意外怀孕并存促使人们开展了一系列关于双重保护的工作，即同时预防艾滋病毒和意外怀孕。本研究将双重保护和双重方法作为感染艾滋病毒女性的一种降低风险策略进行考察。数据来自2003年至2004年巴西五个地区13个市专门的性传播感染/艾滋病公共卫生服务诊所接待的艾滋病毒阳性女性横断面样本（N = 834）。采用描述性技术和逻辑回归分析来考察感染艾滋病毒女性中的双重保护情况。我们扩大了双重保护的定义，将持续使用避孕套和可逆/不可逆避孕方法纳入其中，检验双重方法假说，即使用双重方法的女性与仅使用避孕套的女性相比，使用避孕套的持续性更低，并且我们确定了双重保护的预测因素。双重保护在我们的样本中很常见。使用双重方法的女性持续使用避孕套的几率低于仅使用避孕套的女性。在使用双重方法的女性中，我们发现使用不可逆方法的女性比使用可逆方法的女性更持续地使用避孕套。接受抗逆转录病毒治疗且伴侣为艾滋病毒血清学不一致的女性持续使用避孕套的几率高于其他女性。
