Anemia “101”

The Basics

Page 7: Addressing Anemia Full Spectrum_Klemm_5.11.11

–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.

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20% decreased risk of maternal mortality (Murray-Kolb, 2010, unpublished)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

Page 15: Addressing Anemia Full Spectrum_Klemm_5.11.11

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?
