美国华盛顿大学Simon I. Hay课题组揭示2000年至2018年中低收入国家育龄妇女的贫血患病率。2021年10月12日出版的《自然—医学》发表了这项成果。

研究人员对82个中低收入国家（LMIC）育龄妇女（15-49岁）的贫血患病率进行了2000-2018年的地理空间估计，按严重程度对贫血进行分层，并将结果汇总到与政策相关的行政和国家层面。此外，研究人员还提供了国家以下级别的差异分析，用于全面概述这些国家内贫血患病率的不平等情况，并预测实现世界卫生组织全球营养目标（WHO GNT）的进展，即在2030年前将贫血减少一半。

这些研究结果表明，总体贫血患病率普遍得到了适度的改善，但仅有三个中低收入国家在全国范围内很有可能在2030年前实现世界卫生组织的全球营养目标，而且没有一个中低收入国家预计会在其所有国家以下的行政单位实现这一目标。这个地图显示了国家内部的巨大差异，以及可能达不到世卫组织GNT目标的地区，提供了精确的公共卫生工具，从而使充分的资源分配和后续干预措施能够针对最脆弱的人群。

据了解，贫血是全球妇女普遍存在的一种状况，与全世界的经济生产力下降和死亡率上升有关。

Abstract: Anemia is a globally widespread condition in women and is associated with reduced economic productivity and increased mortality worldwide. Here we map annual 2000–2018 geospatial estimates of anemia prevalence in women of reproductive age (15–49 years) across 82 low- and middle-income countries (LMICs), stratify anemia by severity and aggregate results to policy-relevant administrative and national levels. Additionally, we provide subnational disparity analyses to provide a comprehensive overview of anemia prevalence inequalities within these countries and predict progress toward the World Health Organization’s Global Nutrition Target (WHO GNT) to reduce anemia by half by 2030. Our results demonstrate widespread moderate improvements in overall anemia prevalence but identify only three LMICs with a high probability of achieving the WHO GNT by 2030 at a national scale, and no LMIC is expected to achieve the target in all their subnational administrative units. Our maps show where large within-country disparities occur, as well as areas likely to fall short of the WHO GNT, offering precision public health tools so that adequate resource allocation and subsequent interventions can be targeted to the most vulnerable populations.
