Emily M. Teshome et al. BMC Public Health (February, 2018).

In this study, researchers compare sachet count or self-reporting forms to electronic devices for measuring adherence to daily home fortification with micronutrient powders (MNP) and measure the association between each adherence assessment method and change in hemoglobin concentration. To measure MNP use among young Kenyan children, parents were given a medication event monitoring system (MEMS), a self-reporting form, and were also instructed to keep empty sachets. Researchers found that self-reporting and sachet count were associated with over-reporting compared to monitoring using MEMS. When adherence was measured with MEMS, children with high adherence had higher hemoglobin at the end of the intervention compared to those with low adherence. However, this association was not seen when adherence was measured by self-report or sachet count, suggesting assessment by the electronic device is more reliable.

Megan Parker et al. PLoS ONE (January, 2018).

Researchers evaluated the accuracy of anemia diagnosis using HemoCue Hb 201+ wicking and gravity blood sampling methods and a noninvasive device. Venous blood samples taken from Rwandan children 6-59 months of age compared these three methods against a standard reference measured with a hematology analyzer. Results showed that the HemoCue gravity method was the most accurate. However, use of the HemoCue gravity method in low-resource settings is limited, while the use of the noninvasive method requires less training of health workers and can increase patient and caregiver acceptability, reduce the risk of infection, and reduce the burden on supply, making the non-invasive method promising for use in low-resource settings.

This study assessed IFA supplementation programs in seven countries to better understand barriers and enablers for improved coverage and utilization of IFA supplements during pregnancy. Researchers conducted focus-group discussions and interviews with women, health care providers, and social influencers to analyze knowledge, attitudes, and practices associated with IFA supplementation. Authors concluded that there is a need to strengthen demand for antenatal care, especially during the first trimester, and to create an environment where IFA supplementation adherence is normalized. In addition, improved delivery of IFA supplementation (including the use of community-based delivery and counseling) and supply chain management are necessary for reducing systemic barriers.

Andrew M. Prentice Annuals of Nutrition & Metabolism (December, 2017).

Hepcidin is a liver-derived hormone discovered in the late 2000s, considered to be the master regulator of iron. The article describes the interaction of hepcidin and ferroportin (a cellular iron exporter) and highlights that prolonged inflammation reduces bioavailable iron and makes supplemented iron less effectively absorbed, potentially causing iron deficiency and anemia. Prior to this discovery, most research focused on dietary factors leading to iron deficiency and anemia. With the new understanding of the role of hepcidin, researchers acknowledge the importance of infection and inflammation, providing better evidence for effective preventative and therapeutic interventions to address iron deficiency and anemia.

Guy-Marino Hinnouho et al. Journal of Clinical Pathology (December, 2017).

This study compared the accuracy of HemoCue Hb301 versus XT-1800i, Mindray BC-3000Plus, or both automated analyzers combined. Researchers collected capillary and venous blood from Laotian children ages 6-23 months to compare hemoglobin measurement across methods. Authors concluded that HemoCue showed bias toward high hemoglobin concentration compared to the automated analyzers, meaning use of HemoCue resulted in a significantly lower prevalence of anemia. Because HemoCue is commonly used in field settings, further research is needed to better train phlebotomists and implement appropriate standardized practices to ensure accurate hemoglobin assessment.

Reynaldo Martorell et al. Food and Nutrition Bulletin (September, 2017).

This study examined three food fortification programs in Latin America to identify lessons learned for the design and implementation of successful fortification programming. Researchers gathered data on the history of food fortification programs in each country and information on factors that contributed to successes and challenges the programs faced. Authors found that the highly centralized milling industry in each country and willing industry buy-in were factors that supported program success. In addition, the presence of institutions with good research capacity and champions of fortification were important for program success. The study concluded that fortification programs should consider these contextual factors, develop private/public partnerships, and ensure appropriate contextual program design and comprehensive monitoring and evaluation.

Mary A Uyoga et al. Maternal & Child Nutrition (October, 2017).

The WHO recommends exclusive breastfeeding of infants for six months after birth. Breastmilk contains all the nutrients an infant needs in the first six months of life but is low in iron. This cross-sectional study sought to determine if the duration of exclusive breastfeeding is associated with anemia and iron deficiency in Kenyan infants. Researchers tested for hemoglobin, plasma ferritin, sTfR, and C-reactive protein in 134 infants, and collected data on age, gender, duration of exclusive breastfeeding, weaning foods, and level of income. Months of exclusive breastfeeding was significantly correlated with both hemoglobin (positively correlated) and sTfR (negatively correlated), suggesting that in infants in rural Kenya, longer exclusive breastfeeding is associated with better iron status.

Sarah Hanieh et al. BMJ Global Health (September, 2017).

This study assessed anthropometric measurements and developmental and laboratory outcomes in children born to women who received daily iron and folic acid (IFA) supplementation, twice weekly IFA, or twice weekly multiple micronutrient (MMN) supplementation (all with 60 mg of elemental iron) during pregnancy. At 36 months of age, children of mothers provided with low-dose iron supplementation during pregnancy (twice weekly IFA or MMN) had lower heights, lower height-for-age z-scores, and lower motor composite scores at 36 months than children of mother provided with daily IFA. Authors concluded that daily IFA has beneficial effects on child growth at 36 months of age in comparison with low-dose supplementation.

Marcela de Sa Barreto da Cunha et al. Food Science and Nutrition (February, 2018).

Researchers conducted a systematic review and meta-analysis to assess the effect of vitamin A supplementation (VAS) on iron status biomarkers and anemia in children, teenagers, and pregnant or lactating women. Results showed that VAS was significantly associated with a reduced risk of anemia and increased levels of hemoglobin. However, no association was observed between VAS and prevalence of iron deficiency, despite increased levels of ferritin. Authors concluded that VAS may reduce the risk of anemia by improving levels of hemoglobin and ferritin in individuals with low serum retinol levels.

Maxwell A. Barffour et al. Tropical Medicine and International Health (January, 2018).

This study evaluated the effects of adjusting prevalence of iron deficiency and iron deficiency anemia (IDA) for inflammation alone versus inflammation and malaria during low and high malaria transmission seasons. Venous blood samples were collected from Zambian children during the low malaria and high malaria seasons, respectively. Researchers found that, at a population-level, correcting for malaria and inflammation accounted for statistically significant changes in the estimated prevalence of iron deficiency and IDA, suggesting that by adjusting for both factors, the reliability of iron deficiency and IDA prevalence estimates within and across malaria seasons can be improved.

Sant-Rayn Pasricha et al. The Lancet (February, 2018).

Current hemoglobin thresholds used to define anemia were originally proposed by the WHO in 1968. Informed by data from studies of predominantly white European and North American populations, these thresholds failed to account for variations such as the method of measurement, geography, race, and age. Recognizing the critical impact these guidelines have in both clinical and public health practice, a group of anemia experts from low-, middle-, and high-income countries convened to assess hemoglobin measurement and anemia definition guidelines. The group aims to develop new guidelines that ensure appropriate standardization of hemoglobin measurements across a range of methods and consider physiological, environmental, and genetic factors in determining appropriate thresholds.

Luke R. Smart et al. Springer Nature (November, 2017).

This study evaluated sensitivity of a point-of-care (POC) immunoassay (Sickle SCAN) to diagnose sickle cell disease and a first generation POC color-based assay to detect anemia, in comparison to their respective laboratory-based gold standards. Researchers collected blood samples from Tanzanian children 21 years of age or younger who were at risk for sickle cell disease or anemia. They compared the POC sickle cell assay to hemoglobin electrophoresis results and the POC anemia assay to automated hematology analyzer results. Even when used by providers who were unfamiliar with the assay, the sickle cell disease POC assay provided excellent sensitivity. The hemoglobin POC assay (measuring anemia) was less accurate than the sickle cell assay. However, its specificity was still more effective than using clinical signs to diagnose anemia.

This study explored the impact of providing salt fortified with iron and iodine to Indian children in second grade on anemia and cognition. Baseline and endline data were collected from children in the intervention and control groups, and fortified salt was delivered through the school feeding program to the intervention group over three months. Researchers found that children who received fortified salt were less likely to suffer from anemia and had higher school attendance. Reading and math outcomes were statistically insignificant; however, both were positively influenced by higher school attendance.

The Accelerated Reduction Effort on Anaemia (AREA) Community of Practice (COP), facilitated by the United Nations System Standing Committee on Nutrition (UNSCN) and moderated by the U.S. Agency for International Development's (USAID’s) SPRING project, was launched in June 2015. The AREA COP provides a unique opportunity to connect with other professionals and stay abreast of the latest developments in anemia-related research, policy, and implementation. Since the AREA COP’s creation in May 2015, it has grown to more than 800 members from over 70 countries. The COP webinar series presents cutting-edge and timely topics to members based on their feedback and the latest happenings in the field.

On April 11, 2018, the COP will host its eighth webinar, entitled ”Changing the way we think about the cost-effectiveness of addressing childhood anemia.” Dr. Steve Vosti and Emily Baker will present on a costing study conducted in rural Uganda which explored two methods of micronutrient powder distribution for addressing iron deficiency anemia in children ages 6-23 months. Presenters will review key reasons why nutrition interventions should consider cost, important costs to consider, and what emerged from the nine-month pilot in Uganda. The webinar recording and slides will be made available online for those unable to attend.

In addition to hosting webinars, the COP disseminates anemia-related vacancies, training opportunities, conference announcements, recent publications, and reports, many of which are then discussed among members. On average, the COP circulates five discussion topics per month, which aim to keep members abreast of the science and programming behind multi-sectoral anemia control. In the last six months, the following are some of the topics that were shared among the group:

  • An informative discussion was held on a shared article detailing evidence on iron safety.
  • The COP hosted a webinar on using the FAO/WHO Global Individual Food Consumption Data Tool to understand and plan programs to combat iron deficiency-related anemia.
  • Members engaged in a discussion on how to address high variability in HemoCue hemoglobin concentration measurement.
  • An informative debate was held among members on the effectiveness and relevance of current vitamin A supplementation programs, which ultimately play a role in anemia control.
