Overview
• Anemia “101” & the case for integration
• New Scientific Findings
• Interventions: What works? Effective? Safe?
• Implementation: What needs more work?
• Opportunities for Integration
Anemia “101”
The Basics
–Defined as… Hemoglobin (Hb) concentration <2 standard deviations of the age- and sex specific normal reference–Hb binds to oxygen and carries it to tissues–Red blood cells (RBCs) consist mostly of Hb.–Commonly used indicator to screen for iron deficiency in population-based surveys but not specific for iron deficiency
Anemia
Normal RBCs Anemic RBCs
Not all anemia is caused by iron deficiency….but iron deficiency is a major cause in many dev’g countries.

New Scientific Findings
Anemia is one of the most widespread disorders in the world.

New Scientific Evidence• Improving Hb by 1 g/dL in pregnancy is associated with a
20% decreased risk of maternal mortality (Murray-Kolb, 2010, unpublished)
• Maternal IFAS associated with 50% ↓ in very pre-term births & 54% ↓ early neonatal mortality (Zeng L, BMJ 2008)
• Nepalese women receiving IFA in pregnancy had 16% ↓ in LBW & 60 g ↑in birth weight (Christian P; BMJ, 2003)
• Maternal IFA ↓ mortality among Nepalese children by 31% between birth & 7 years (Christian P; Am J Epidemiol, 2009)
• IFA during ANC associated with 90% ↓ in early neonatal deaths in Indonesia (Titaley CR, Bull World Health Organ, 2009)
• IFA + IPTp in mothers associated with 24% ↓ in neonatal deaths 19 countries Sub-Saharan Africa (Titaley CR et al, AJCN, 2010)
Growing body of evidence that maternal anemia interventions are not only important for the
health of the mom, but also for her neonate, and child
Are we making progress on
reducing maternal anemia?

Cautionary Comments for iron supplementation in malaria-endemic areas”
• WHO (2007): “Universal iron supplementation (i.e. use of medicinal iron as pills or syrups) should not be implemented without the screening of individuals for iron deficiency, because this mode of iron administration may cause severe adverse events in iron-sufficient children”
• Cochrane review (2009): “Iron supplementation does not increase risk of clinical malaria or death, when regular malaria surveillance and treatment services are provided. There is no need to screen for anemia prior to iron supplementation”
Implementation-What needs more work?

But SOME women will experience difficulties. They need to be found, listened to & counseled.

Actions Needed• Most countries have MMR reduction goals: Is maternal
anemia and iron and folic acid (IFA) supplementation given high priority?
• ANC guidelines include preventive IFA: But is the implementation being monitored? effective?
• Varied causes of anemia, e.g. Iron-deficiency, hookworm, malaria: Is there an integrated package of services? Is there “buy in” & agreement across sectors?
• Essential Drugs Lists have IFA, deworming, malaria drugs: How can “stock outs” be eliminated?
• Basic health worker training covers anemia: How adequate is counseling and compliance follow-up?
