What percent of the US population has iron deficiency anemia?
The prevalence of iron deficiency anemia is 2 percent in adult men, 9 to 12 percent in non-Hispanic white women, and nearly 20 percent in black and Mexican-American women. Nine percent of patients older than 65 years with iron deficiency anemia have a gastrointestinal cancer when evaluated.
What percentage of the world’s population is iron deficiency?
Iron deficiency with or without concurrent anemia affects ≈30% of the global population, making it the most widespread nutrient deficiency (1).
How many people have died from iron deficiency?
Based on these estimates of iron deficiency anaemia as a risk factor for mortality, iron deficiency is estimated to cause 591000 perinatal deaths and 115000 maternal deaths globally.
How common is anemia in the United States?
Anemia is the most common blood disorder, and according to the National Heart, Lung, and Blood Institute, it affects more than 3 million Americans.
Who is most at risk for iron deficiency anemia?
Women. Because women lose blood during menstruation, women in general are at greater risk of iron deficiency anemia. Infants and children. Infants, especially those who were low birth weight or born prematurely, who don’t get enough iron from breast milk or formula may be at risk of iron deficiency.
Which country has the most iron deficiency?
Iron-deficiency anaemia has remained the top cause of disability in India for 10 years now, according to an IndiaSpend analysis of the last two Global Burden of Disease (GBD) surveys.
Where in the world is anemia most common?
Iron deficiency (ID) is estimated to be the most common cause of anemia worldwide and is particularly prevalent in developing nations in Africa and Asia (2). Other nutritional deficiencies certainly play a role in the occurrence of anemia, but the global prevalence data for these deficiencies are limited.
What are the chances of dying from iron deficiency?
Case fatality rates, mainly for hospital studies, varied from 1% to 50%. The relative risk of mortality associated with moderate anemia (hemoglobin 40 – 80 g/L) was 1.35 [95% confidence interval (CI): 0.92–2.00] and for severe anemia (47 g/L) was 3.51 (95% CI: 2.05–6.00).
Is iron deficiency anemia life threatening?
If left untreated, iron-deficiency anemia can cause serious health problems. Having too little oxygen in the body can damage organs. With anemia, the heart must work harder to make up for the lack of red blood cells or hemoglobin. This extra work can harm the heart.
Where is iron deficiency most common?
Iron deficiency (ID) is estimated to be the most common cause of anemia worldwide and is particularly prevalent in developing nations in Africa and Asia (2).
What population is most at risk for iron deficiency anemia?
Pregnant women and women of childbearing years Women of childbearing age are the population with the most affected individuals, with an estimated 468 million being non-pregnant women, according to WHO1 and are the highest at-risk population group for iron-deficiency anemia.
Is anemia more common in males or females?
Overall, anemia is twice as prevalent in females as in males. This difference is significantly greater during the childbearing years due to pregnancies and menses. Approximately 65% of body iron is incorporated into circulating Hb.
What are the tests for iron deficiency and anaemia?
Endoscopy. Doctors often check for bleeding from a hiatal hernia,an ulcer or the stomach with the aid of endoscopy.
Should we screen for iron deficiency anaemia?
Haemoglobin is the most commonly used screening test for iron deficiency, but may have inadequate sensitivity and specificity to determine iron status in many settings. Screening for anaemia during pregnancy is widely recommended . In children, studies evaluating screening programs have found problems with implementation, acceptability and follow-up of testing, and most international authorities do not support this practice.
What is the global prevalence of iron deficiency anemia?
As such, iron deficiency is the most common cause of anemia worldwide. Iron deficiency anemia afflicts a subset of the two billion people worldwide who are nutritionally iron deficient (Viteri 1998). Therefore, the health burden of iron deficiency may be extrapolated from the global prevalence of anemia.
What are the statistics of anemia?
Statistical analysis using SAS examined temporal trends and the prevalence of anemia among sexes, age groups, and races/ethnicities. The study estimated that an average of 5.6% of the U.S. population met the criteria for anemia and 1.5% for moderate-severe anemia during this 10-year period.
