Introduction
· Over 800 million women are affected by anemia globally1.
·
The poorest nations of
the world suffer 60% of the morbidity and 95% of the mortality due to iron
deficiency1.
· South Asia and sub-Saharan Africa bear about 70% of the global iron-deficiency anemia mortality burden1.
·
Anemia takes up 12.8% of
maternal deaths during pregnancy and childbirth in Asia1.
·
In India, anemia stands
as a major public health problem, since about 52% of nonpregnant women of
reproductive age are anemic1.
Causes of Anemia
·
The primary cause of anemia remains iron deficiency but it is rarely found alone1.
·
It coexists with various
other causes like malaria, parasitic infection, nutritional deficiencies, and
hemoglobinopathies1.
·
The influence of iron deficiency as a cause of anemia differs with the region.
·
Nearly 50% of anemia in sub-Saharan Africa is because of iron deficiency due to the high prevalence of HIV, hookworm, malaria, and other infectious diseases1.
·
Over 70% of premenopausal
women in India suffer from anemia caused by iron deficiency1.
Consequences of Anemia
·
Iron deficiency anemia
increases the risk for preterm labor, low birth weight, infant mortality, and
predicts iron deficiency in infants after 4 months of age1.
·
It also causes cognitive
deficits and reduced intellectual performance among school children1.
·
In regions with a high prevalence of iron deficiency, successful iron
supplementation causes dissolution of anemia as a public health problem (except
where malaria and HIV or hookworm infection rates are high)1.
·
Moderate-to-severe anemia (hemoglobin level below 10 g/dL) are related to significant
public health implications1.
Solicitudes
·
Although there has been increased national and international awareness and recent governmental intervention programs, the prevalence of anemia among Indian women is constantly higher than 45% since 1990, and anemia trends remain strongly correlated
with iron deficiency1.
·
The main causes of iron deficiency anemia in India are low dietary intake, poor availability of iron, chronic blood loss due to hookworm infestation and malaria1.
Indian Dietary Pattern is a Concern for Anemia
·
Vegetarianism, defined as
the exclusive consumption of plant-based diets, is a common dietary pattern in
India, for at least 2500 years. In India, vegetarianism is due to ethical
teachings of “nonviolence” inherent in Hinduism, Buddhism, and Jainism1.
·
Indians constitute about
70% of the world’s population who adhere to vegetarian-style diets1.
·
Seventy-five percent of Indian vegetarians are lactovegetarians, who do not consume meat or eggs, with no prohibition for milk or other dairy products1.
·
Twenty-five percent of
Indian vegetarians are lacto-ovo vegetarians, who do not eat meat, with no
prohibition on eggs and dairy products1.
·
Further, the popular and
affordable foodstuffs in India like wheat bread contain high levels of
phytates. Also, tea a popular beverage in India is high in tannic acid content.
Phytates and tannins further inhibit iron absorption1.
·
Less than 1% of Indians are vegans, who do not consume any animal products at all1.
Dietary Recommendations
·
Nutritionists recommend vegetarians to increase dietary iron by 80% to compensate for a lower iron availability of 10% from a vegetarian diet compared with 18% from an omnivorous diet
1.
·
This recommendation is challenging for Indians where the majority of vegetarians sustain on inadequate quantities of iron - poor staples like lentils, wheat bread, green peppers, and rice1.
·
A modified food guide pyramid for vegetarians recommends including 32-36 mg of iron daily in a 2,000 calorie diet comprising 8 servings of grains, 3 of vegetables, 2.5 of green leafy vegetables, 1.5 of fruit, 2.5 of beans and protein foods,
3 of dairy or nonfortified dairy, 1.5 of nuts and seed, and 2.5 of oils1.
Strategies to Prevent Anemia among Indian
Women
Advocate
Consuming meat,
fish, chicken, or egg daily or several times weekly can significantly lower the
level of anemia1.
Educate
Spreading knowledge about the importance of
iron-rich foods in diet and iron fortification of vegetarian diets will help
Indian women fight anemia1.
Food-based Strategies
Food-based strategies to educate Indian women
should include:
·
Consumer education to promote diversification of the diet including iron-rich foods1
·
Popularizing and making accessible the foods and fruits containing vitamin C, which enhances iron absorption
1
·
Behavior modification
should be done to encourage women to avoid consuming tea with meals since tea
interferes with iron absorption1.
Promote
Iron-rich food sources like millet (Ragi ganji),
should be promoted to be consumed either as roti bread or as malt beverage.
Ragi ganji is higher in iron and contains less iron-inhibiting phytates than
rice, wheat and maize1.
Regional Strategies
Mass food fortification with iron, iron
supplementation programs for women and children, implementing effective
programs for the prevention of malaria and hookworm, and effective public
education about iron-rich sources of plant-based and animal-based foods will
serve as effective strategies for reducing the incidence and prevalence of iron
deficiency anemia among Indian women1.
Who Guideline: Daily Iron Supplementation in Adult Women
and Adolescent Girls2
|
Target Group
|
Menstruating adult women and
adolescent girls (nonpregnant females in the reproductive age group)
|
Supplement composition
|
30-60 mg elemental irona
|
Supplement form
|
Tablets
|
Frequency
|
Daily
|
Duration
|
Three consecutive months in a year
|
Settings
|
Where the prevalence of anemia in
menstruating adult women and adolescent girls is 40% or higherb
|
a30-60 mg of elemental iron equals
150-300 mg of ferrous sulfate heptahydrate, 90-180 mg of ferrous fumarate or
250-500 mg of ferrous gluconate.
bIn the absence of prevalence data in
this group, consider proxies for high risk of anemia. For the most recent
estimates, visit the WHO - hosted Vitamin and Mineral Nutrition Information
System (VMNIS).
