We examined contraceptive use and dual protection in the postpartum period in a Prevention of Mother to Child Transmission population and whether it varied by HIV status.
Data are from a prospective study, the South Africa HIV Antenatal Post-test Support Study. Pregnant participants were recruited from a government clinic in an urban township, and the analytic sample was 821. Following enrollment, participants were tested for HIV and administered a questionnaire at baseline and 14 weeks postpartum. We used generalized linear regression models to examine HIV status and use of modern contraceptives at 14 weeks.
The risk ratio of condom use at 14 weeks postpartum was 1.66 [95% confidence interval (CI): 1.36-2.02] for HIV-positive compared to HIV-negative women. The risk ratio for dual protection (use of a condom and a hormonal method) was 1.96 (95% CI: 1.39-2.79) at 14 weeks for HIV-positive compared to HIV-negative women.
HIV positive status may be a motivating factor for women to use condoms and dual protection. In this setting where HIV is highly prevalent, it is ever more important that women control the timing and limiting of births so as to preserve the health of the mother and child.

我们在预防母婴传播人群中研究了产后避孕措施的使用及双重保护情况,以及其是否因艾滋病毒感染状况而异。
数据来自一项前瞻性研究,即南非艾滋病毒产前检测后支持研究。怀孕参与者从一个城市乡镇的政府诊所招募,分析样本为821人。入组后,参与者接受艾滋病毒检测,并在基线和产后14周进行问卷调查。我们使用广义线性回归模型来研究产后14周时的艾滋病毒感染状况和现代避孕措施的使用情况。
与艾滋病毒阴性女性相比,艾滋病毒阳性女性在产后14周使用避孕套的风险比为1.66[95%置信区间(CI):1.36 - 2.02]。与艾滋病毒阴性女性相比,艾滋病毒阳性女性在产后14周采取双重保护(使用避孕套和激素避孕方法)的风险比为1.96(95%CI:1.39 - 2.79)。
艾滋病毒阳性状况可能是女性使用避孕套和采取双重保护的一个促动因素。在艾滋病毒高度流行的这种环境下,女性控制生育时间和限制生育对于维护母婴健康更为重要。
艾滋病毒感染状况可能是女性在产后使用避孕药具和采取双重保护的一个重要促动行为因素。
