Consumption of multiple micronutrient supplements (MMS) during pregnancy offers additional benefits compared with iron-folic acid (IFA) supplementation, but the tablets are more expensive. We estimated the effects, costs, and cost-effectiveness of hypothetically replacing IFA supplements with MMS for 1 year in Bangladesh and Burkina Faso. Using baseline demographic characteristics from LiST and effect sizes from a meta-analysis, we estimated the marginal effects of replacing IFA with MMS on mortality, adverse birth outcomes, and disability-adjusted life years (DALYs) averted. We calculated the marginal tablet costs of completely replacing MMS with IFA (assuming 180 tablets per covered pregnancy). Replacing IFA with MMS could avert over 15,000 deaths and 30,000 cases of preterm birth annually in Bangladesh and over 5000 deaths and 5000 cases of preterm birth in Burkina Faso, assuming 100% coverage and adherence. We estimated the cost per death averted to be US$175-185 in Bangladesh and $112-125 in Burkina Faso. Cost per DALY averted ranged from $3 to $15, depending on the country and consideration of subgroup effects. Our estimates suggest that this policy change would cost-effectively save lives and reduce life-long disabilities. Improvements in program delivery and supplement adherence would be expected to improve the cost-effectiveness of replacing IFA with MMS.
怀孕期间服用多种微量营养素补充剂(MMS)比铁叶酸(IFA)补充剂有额外的益处,但 MMS 片的价格更贵。我们假设在孟加拉国和布基纳法索,用 MMS 替代 IFA 补充剂进行为期一年的替代,以此来评估该替代的效果、成本和成本效益。我们使用 LiST 的基线人口特征和荟萃分析的效果大小来估计用 MMS 替代 IFA 对死亡率、不良出生结局和避免的残疾调整生命年(DALY)的边际效应。我们计算了用 IFA 完全替代 MMS 的边际片剂成本(假设每个覆盖的妊娠有 180 片)。假设 100%的覆盖率和依从性,用 MMS 替代 IFA 每年可以避免孟加拉国超过 15000 人死亡和 30000 例早产,以及布基纳法索超过 5000 人死亡和 5000 例早产。我们估计孟加拉国每例死亡避免的成本为 175-185 美元,布基纳法索每例死亡避免的成本为 112-125 美元。避免每例 DALY 的成本范围为 3 至 15 美元,具体取决于国家和对亚组效应的考虑。我们的估计表明,这种政策变化将以具有成本效益的方式拯救生命并减少终身残疾。预计改善项目交付和补充剂的依从性将提高用 MMS 替代 IFA 的成本效益。
