Malnutrition

The ‘other end’ of malnutrition
An escalating global epidemic of overweight and obesity – “globesity” – is taking over many parts of the world. If immediate action is not taken, millions will suffer from an array of serious health disorders.
Obesity is one of today’s most blatantly visible – yet most neglected – public health problems. Paradoxically coexisting with undernutrition.

Protein Energy Malnutrition
“Protein-energy malnutrition (PEM) is by far the most lethal form of malnutrition. Children are its most visible victims. Malnutrition, “the silent emergency,” is an accomplice in at least half of the 10.4 million child deaths each year. These young lives are prematurely – and needlessly – lost “

Slide 5

Who is at Risk?
Protein Energy Malnutrition
People of impoverished countries
seen in the midst of drought or political turmoil.
However as many as 50% of elderly persons in nursing homes in the U.S. suffer from protein-calorie malnutrition.
Children
Pregnant women

Micronutrient Deficiency
Called “micronutrients” because they are needed in only miniscule amounts, these substances are the “magic wands” that enable the body to produce enzymes, hormones and other substances essential for proper growth and development.
As tiny as the amounts are, the consequences of their absence are severe. Their lack represents a major threat to the health and development of populations the world over, particularly to preschool children and pregnant women in low-income countries.

Global Health Macronutrient Deficiency
Iodine
Vitamin A
Iron

Vitamin A Deficiency
Vitamin A deficiency causes night blindness and is the single most important cause of childhood blindness in developing countries. Every year, about 500,000 children lose their sight as a result of vitamin A deficiency. The majority (about 70%) die within one year of losing their sight.

Vitamin A Deficiency
Vitamin A deficiency increases the risk of severe illness, and even death, from common childhood infections such as diarrheal diseases and measles. In developing countries 200–300 million children of preschool age are at risk of vitamin A deficiency.

Vitamin A Deficiency
Vitamin A deficiency may increase the risk of maternal mortality in pregnant women. Nearly 600,000 women die from childbirth-related causes each year, the vast majority of them from complications which could be reduced through better nutrition, such as vitamin A.

Iron Deficiency
"As many as 4–5 billion people, 66–80% of the world's population, may suffer from reduced learning ability and work capacity due to iron deficiency. More than 30% of the world's population, are anemic "
Battling iron deficiency anemia WHO 2002

Iron Deficiency
Iron deficiency impairs the cognitive development of children through to adolescence.

Iron Deficiency
Iron deficiency damages immune mechanisms, and is associated with increased morbidity rates.

Iron Deficiency
Iron deficiency impairs physical work capacity in men and women by up to 30%.

Iron Deficiency
Iron deficiency during pregnancy is associated with multiple adverse outcomes for both mother and infant, including increased risk of sepsis, maternal mortality, perinatal mortality, and low birth weight.

Iron Deficiency
Iron deficiency and anemia reduce learning ability and the work capacity of individuals and entire populations, bringing serious economic consequences and obstacles to national development.

Epidemiology of Iron Deficiency in the US
prevalence of iron deficiency was greatest
toddlers aged 1--2 years (7%)
adolescent and adult females aged 12--49 years (9%--16%)
The prevalence of iron deficiency was approximately two times higher among non-Hispanic black and Mexican-American females (19%--22%) than among non-Hispanic white females (10%).

Manifestations of Iron Deficiency
Pale skin (race)
Fatique
Irritability
Weakness

Laboratory Findings in Iron Deficiency Anemia
Low Hgb/Hct
High RDW (microcytic cells)
Follow up with iron studies
Low serum ferritin
Low serum iron
High TIBC

* Get a good history, rule out other cause for anemia ie. LEAD

Preventing Iron Deficiency
Iron is found in foods like red meat, egg yolks, and fortified flour, bread, and cereal
Breast feeding & iron fortified formula
Screening

Iodine Deficiency
Iodine deficiency is the number one cause of preventable brain damage, affecting millions of people worldwide.
  Assessment of Iodine Deficiency Disorders and Monitoring their Elimination: A Guide for Programme Managers 2nd edition. WHO/UNICEF/ICCIDD 2001

Iodine Deficiency
The problem of iodine deficiency is especially serious for pregnant women and young children. During pregnancy, even a mild deficiency of iodine can reduce brain development of the fetus limiting the intellectual ability of an individual for life.

Iodine Deficiency
Iodine deficiency can cause severe mental and physical retardation, known as cretinism.

Iodine Deficiency
Iodine deficiency in chronic form, can cause goiter (a disorder characterized by swelling of the thyroid gland) in both adults and children.

Iodine Deficiency
Iodine deficiency most commonly, impedes fetal brain development. At the population level, the consequence of iodine deficiency is a 10–15% lower average intellectual quotient (IQ), which affects the social and economic development of both communities and nations.

Iodine Deficiency
The World Bank has estimated that, combined with vitamin A deficiency and iron deficiency, iodine deficiency may lower the economic wealth of a nation by as much as 5% every year.

"Case study:"
Case study:
Zacharia arrives in East Harlem

Manifestations of Iodine Deficiency
Goiter-enlarged thyroid cells and gland
Hypothyroidism: iodine is essential for the production of thyroid hormones and normal thyroid function
Cretinism: physical and mental retardation

Manifestations of Iodine Deficiency
Symptoms of hypothyroidism
Mental and physical sluggishness
Weakness
Fatigue
Cold intolerance
Weight gain
Depression
Many more . . .

Where is Iodine Deficiency?
Land locked areas without iodized salt: Asia, Central Africa
Endemic goiters occur within groups of people iving in geographical areas with iron depleted soil

Laboratory Findings
TSH high
Thyroid hormones low (T3 and T4)

Preventing Iodine Deficiency?
Iodized salt
Seafood: fish and kelp
Dairy products
Plants grown in iodine rich soil

Folic Acid Deficiency
An estimated 300,000 children are born each year with spina bifida and anencephaly, which are severe neural tube defects. Approximately 75%, 225,000, of these affected births could be prevented through increased consumption of synthetic folic acid by all women of reproductive age.

Gastrointestinal Parasites
(Often associated with malnutrition)

The Culprits
Ascaris lumbricoides (Round worm)
Trichurist (Whipworm)
Ancylostoma (Necator, Hookworm)
