Anemia remains a critical global public health concern and practical approaches to assessing anemia and its key determinants are required in both clinical and public health settings. To achieve global goals for anemia reduction, greater reliability, precision, and consistency of anemia assessment approaches are needed. Standardized approaches to assess anemia and its causes are essential to reliably assess progress on global goals for anemia reduction. The “Anemia Assessment” section provides a brief review of how to assess anemia based on hemoglobin concentrations cutoffs that correspond to age, sex, and physiologic status. The “Causes of Anemia” section discussed how to assess the likely causes of anemia in different settings.

The causes of anemia are broadly classified as non-nutritional (e.g., due to infection, inflammation, blood loss, or genetic disorders) or nutrition-specific (e.g., due to deficiencies in iron, vitamin A, riboflavin, vitamin B12, or folate). The section on “Using Survey Data for Program Decision Making” introduces a framework for assessing anemia in populations based on the “ecology of anemia”, which recognizes its many overlapping causes. We present a decision tree to inform the anemia-related data that researchers may need to collect in population-based surveys and a supporting table with information on how to collect them. We also describe an approach to interpret anemia risk factor data from population-based surveys that can inform decisions about context-specific interventions.

The USAID Advancing Nutrition Anemia Task force has developed five Anemia Briefs that explore current evidence and practice to understand and address the causes and consequences of anemia, and interventions to reduce the burden of disease. One of those briefs—"Anemia Assessment in Clinical and Public Health Settings”—explore issues related to the assessment of anemia.

In Search of Better Anemia Estimates: USAID Advancing Nutrition’s HEmoglobin MEasurement (HEME) Project
Webinar published by USAID Advancing Nutrition in
At the population level, differences in mean hemoglobin and the distribution of hemoglobin values can result in inaccurate and unreliable estimates of anemia prevalence .
Exploring the Anemia Ecology PART II: Application of the Ecological Approach to Anemia Assessment—Experiences from the Field Webinar
Webinar published by USAID Advancing Nutrition in
The USAID Advancing Nutrition Anemia Task Force (ATF) was created to develop a new approach to address the global challenge presented by anemia. Recognizing that anemia is a multi-dimensional condition affected by both internal (biological, genetics, health/infections, and nutrition) and external (socio-demographic, behavioral, food systems, and…
Hidden No More: New Estimates Help the Nutrition Community Support Women and Children at Risk of Micronutrient Deficiencies
Journal Article published by USAID Advancing Nutrition in
Timely data on the burden of micronutrient deficiencies is essential to understanding what works where and whether we’re making progress. Researchers recently estimated the global and regional prevalence of deficiencies in one or more micronutrients among preschool-age children and non-pregnant women of reproductive age and bring transparency to…
Coffee and Chai Chat: Spotlighting New Global Data and Actions Needed on Hidden Hunger
Webinar published by Micronutrient Forum in
Experts discuss how to enhance data collection and identify the best sources of information, modeling methods used to derive estimates of micronutrient deficiencies and data gaps, hidden hunger among women, and priorities for action. This is a series of webinars.
A Cross-Sectional Study of the Associations between Biomarkers of Vitamin D, Iron Status, and Hemoglobin in South African Women of Reproductive Age: the Healthy Life Trajectories Initiative, South Africa
Journal Article published by Curr Dev Nutr in
This study aimed to assess the associations between serum vitamin D and biomarkers of iron and anemia in a cohort of women of reproductive age from Soweto, South Africa, within a cross-sectional substudy of the Healthy Life Trajectories Initiative South Africa pilot trial.
The Prevalence of Anemia in Children Aged 6–23 Months and Its Correlates Differ by District in Kapilvastu and Achham Districts in Nepal
Journal Article published by Curr Dev Nutr in
This study analyses the predictors of anemia in young Nepali children aged 6–23 months in two districts of Nepal: Kapilvastu and Achham.
Spatial Variation and Attributable Risk Factors of Anaemia Among Young Children in Uganda: Evidence from a Nationally Representative Survey
Journal Article published by PLOS Glob Public Health in
This study describes the spatial variation and attributable risk factors of anemia at the national level in Uganda among children aged 6–59 months, using data from the 2016 Uganda Demographic and Health Survey.
Association between Hemoglobin and Elevation among School-aged Children: A Verification of Proposed Adjustments
Journal Article published by Am J Clin Nutr in
Hemoglobin increases with elevation as an adaptive response to lower blood oxygen saturation. This secondary data analysis examines the cross-sectional association between hemoglobin and elevation among school-aged children with data from nine population-based surveys. The paper calculates the hemoglobin adjustments required for each 500 meter…
