Although iron deficiency is the most common cause, other vitamin and mineral deficiencies, chronic inflammation, parasitic infections, and inherited disorders can all cause anemia. Both anemia and iron deficiency have severe economic and health costs. Iron deficiency anemia compromises a child’s ability to learn, further compromises its future prospects and, in aggregate terms, hinders the development of the population.
The World Health Organization’s WHO most recent estimates suggest that anemia affects around million children and women. Investment in preventing and managing micronutrient malnutrition results in improved health, a reduction in child and maternal mortality, and better earnings with a ‘benefit-to-cost ratio’ of almost 13 to peduatria . Iron deficiency is the world’s most widespread micronutrient deficiency often resulting in chronic iron deficiency or iron deficiency anemia defined by the WHO as hemoglobin levels?
The cut-off values vary by age, sex, altitude, smoking, and pregnancy status 1. To replenish iron stores, men require 0. High iron intake is also required for growth. Another estimate from the University of Toronto found that total cognitive and physical loss due to iron deficiency is around 4.
Anemia has severe health consequences in pregnant women, infants, and children. Anemia in pregnancy has numerous health effects for the baby including increased risks of stunting, blindness, severe illnesses, decreased cognitive performance, spinal, and brain defects. Anemia in pregnancy also increases the risk of miscarriage, stillbirth, and low-birth-weight thus increasing risks of infant mortality as well as birth complications causing hemorrhaging corresponding to an increased risk of maternal depression and maternal mortality .
Additionally, infants and young children with iron deficiency anemia are more likely to have attention deficits, reduced motor coordination, and language difficulties . For school age children, this type of anemia also decreases school participation . There is strong evidence showing that iron treatment for school age children can improve low-test scores of cognitive ability and education achievement 5.
Iron deficiency anemia: Research on iron fortification for efficient, feasible solutions
anemiax It is critical to diagnose the cause of iron deficiency for appropriate treatment. One option to add iron to the diet is the iron fortification the addition of micronutrients to food of staple foods such as wheat flour, maize flour, and rice with iron and other vitamins and minerals. Some condiments, such as salt, fish sauces, and soy sauces can also be fortified carencia,es iron.
Studies have shown that iron fortification corresponds with the reduction of anemia prevalence . For example, the Food Fortification Initiative found evidence that suggests, but does definitively conclude, that anemia prevalence has significantly decreased in countries which utilize micronutrient fortification of flour while has not changed in countries that do not .
Another study looked at the effects of iron fortification of wheat and corn flour and found that fortification had a ‘protective effect’ against gestational anemia .
Fortification of cornmeal and maize flour can improve nutritional status if mandated at the national level in countries where these staples are frequently consumed.
Two COCHRANE reviews are being conducted on the effects of the fortification of maize flour, wheat flour, and aemias with iron and other vitamins and minerals for pediatriz . A review on bioavailability of different iron compounds used in food fortification is available . Another option to prevent and treat anemia is iron supplementation.
This is an effective technique, including as a preventive method to reduce the likelihood of maternal anemia in pregnant women . An intervention in rural Vietnam measured the effects of iron supplementation and iron fortified milk on the hemoglobin status of pregnant women.
The study found that the “hemoglobin concentrations carenciakes both treatment groups were not significantly different” but hemoglobin levels were lower in the comparison groups with iron supplementation . Iron fortification is a cost-effective option: Thus it is incredibly efficient: Excessive iron consumption or overload can be harmful, potentially leading pediafria iron overload and blood disorders . However, iron overload due to extended iron supplement ingestion or fortification of flour is very rare .
Possible side effects of iron include diarrhea, constipation, and nausea with higher doses . To deploy efficient, feasible strategies for iron fortification as a carenciaales to iron deficiency anemia, it is important for each country to address the recommendations of iron nutrition experts and the WHO in a systematic manner including legislation and research, address the bioavailability and the supply of iron fortification, educate the population peditria iron deficiency, and test individuals using clinical pathways for serum or carenciaoes ferritin concentration as an index of iron deficiency and overload, as indicated in the figures 3 and 4 .
There are three main types of fortification recognized by the WHO: Universal iron fortification, when there are no non-fortified options available, potentially puts those with hemochromatosis caused by an increase in iron intake at a greater risk for iron overload. Thus, targeted or market-driven approaches are often favored Groups at highest risk include pregnant women, infants, and school age children.

While there is substantial evidence of the effectiveness of iron fortification and supplements to reduce iron deficiency anemia, the benefits are hindered due to low usage of preventive health services in developing countries, lack of infrastructure and national political drive for larger scale fortification of popular local foods, and incomplete enactment of preventive treatments. It is critical to address these barriers, using research, to effectively prevent iron deficient anemia .
According to a review on iron fortification of wheat flour, “most current iron fortification programs are likely to be ineffective. Legislation needs updating in many countries so that flour is fortified with adequate levels of the recommended iron compounds” .
Thus, countries where flour is an ingredient in staple foods, should adhere to WHO recommendations on levels of iron fortification in wheat and maize flour . It is important for countries to fortify staple foods in their respective countries.
Quality, targeted research is a critical component to addressing iron deficient anemia. Therefore, it is crucial to deploy research strategies with sound metrics allowing valid results comparable between countries and addressing health equity absence of avoidable and unfair differences in health.
R10  all activities to improve health should be informed on evidence therefore more effectively strengthening public health and improving health care outcomes. One efficient way to address lack of iron supply and bioavailability of iron in diets is iron fortification .
Iron fortification may help to reduce iron deficiency anemia, which can have positive development effects across populations including improved cognitive and academic performance as well as decreased child birth defects, maternal and child mortality rates. Improved cognitive and academic performance as well as less days of school missed can translate into a better-trained workforce resulting in economic gains.
Decrease of negative health effects leads to a reduction of health care costs. In summary, there is a potential for efficient, viable conquer of iron deficiency and lack of iron supply which can result in improved health and development.
