2010年,世卫组织建议感染艾滋病毒的妇女母乳喂养12个月,同时接受抗逆转录病毒治疗(ART),以平衡母乳喂养的好处和艾滋病毒传播的风险。为了向2016年世卫组织指南提供信息,我们更新了先前关于母乳喂养持续时间对无艾滋病毒婴儿存活率(HFS)影响的研究,纳入了孕产妇ART持续时间,婴儿/儿童死亡率和母婴传播数据。使用预防艾滋病并发症的成本效益(CEPAC)婴儿模型,我们模拟了母乳喂养持续时间对HIV暴露的未感染婴儿24个月HFS的影响。我们将“最佳”母乳喂养持续时间定义为最大化24个月HFS的持续时间。我们改变了母亲ART持续时间,母乳喂养婴儿/儿童的死亡率,以及与替代喂养相关的相对死亡风险(“RRRF”),模拟为替代喂养婴儿/儿童全因死亡率的乘数(范围:1 [无额外风险]至6)。基础病例模拟RRRF = 3、中位婴儿死亡率和24个月的母亲ART持续时间。在基础病例中,HFS范围为83.1%(未母乳喂养)至90.2%(母乳喂养12个月)。最佳母乳喂养持续时间随着RRRF值的增加和母亲ART持续时间的延长而增加,但随着婴儿死亡率的变化而变化不大。最佳母乳喂养时间往往超过世卫组织以前建议的12个月。在RRRF高和母亲ART持续时间长的环境中,当母亲母乳喂养时间超过先前推荐的12个月时,HFS最大化。在RRRF低或母亲ART持续时间短的情况下,较短的母乳喂养持续时间可优化HFS。如果支持母亲更长时间地使用抗逆转录病毒疗法,就有可能减少传播风险,并获得更长母乳喂养时间的好处。
In 2010, the WHO recommended women living with HIV breastfeed for 12 months while taking antiretroviral therapy (ART) to balance breastfeeding benefits against HIV transmission risks. To inform the 2016 WHO guidelines, we updated prior research on the impact of breastfeeding duration on HIV‐free infant survival (HFS) by incorporating maternal ART duration, infant/child mortality and mother‐to‐child transmission data. Using the Cost‐Effectiveness of Preventing AIDS Complications (CEPAC)‐Infant model, we simulated the impact of breastfeeding duration on 24‐month HFS among HIV‐exposed, uninfected infants. We defined “optimal” breastfeeding durations as those maximizing 24‐month HFS. We varied maternal ART duration, mortality rates among breastfed infants/children, and relative risk of mortality associated with replacement feeding (“RRRF”), modelled as a multiplier on all‐cause mortality for replacement‐fed infants/children (range: 1 [no additional risk] to 6). The base‐case simulated RRRF = 3, median infant mortality, and 24‐month maternal ART duration. In the base‐case, HFS ranged from 83.1% (no breastfeeding) to 90.2% (12‐months breastfeeding). Optimal breastfeeding durations increased with higher RRRF values and longer maternal ART durations, but did not change substantially with variation in infant mortality rates. Optimal breastfeeding durations often exceeded the previous WHO recommendation of 12 months. In settings with high RRRF and long maternal ART durations, HFS is maximized when mothers breastfeed longer than the previously‐recommended 12 months. In settings with low RRRF or short maternal ART durations, shorter breastfeeding durations optimize HFS. If mothers are supported to use ART for longer periods of time, it is possible to reduce transmission risks and gain the benefits of longer breastfeeding durations.
