Sub-Saharan Africa Evidence Gap

The review is motivated by a gap in systematic mapping of trimester-specific anaemia effects and micronutrient aetiology in sub-Saharan Africa. A prior global meta-analysis found only four African studies among 272 studies on anaemia and birth outcomes. The article states that no scientific reviews have examined trimester-specific micronutrient-related anaemia and birth outcome profiles within sub-Saharan African populations. Most existing evaluations of AMR interventions are hospital-based and disproportionately located in high-income countries. Reviews that include low- and middle-income countries often focus on inpatient or tertiary-care settings, leaving community approaches underrepresented. Existing community evidence often documents the scale of non-prescription dispensing, self-medication, and knowledge-attitude-practice determinants rather than testing solutions. A focused sub-Saharan Africa synthesis is needed because intervention effectiveness may depend on local market, regulatory, laboratory, sociocultural, affordability, access, and WASH factors. Understanding the trimester window of greatest harm could inform intervention timing and WHO diagnostic threshold calibrat…
