Which group may be at risk for vitamin B12 deficiency quizlet?

Strict vegetarians (especially vegans) are likely to be deficient unless they take a vitamin B12 supplement. In addition some people lose the ability to absorb vitamin B12 as they age, and others have a genetic defect so they don't produce the intrinsic factor needed for vitamin B12 absorption.

What group is at risk for vitamin B12 deficiency?

According to an analysis of NHANES data from 2015–2016, people of low socioeconomic status, women, and non-Hispanic Blacks are most likely to have low vitamin B12 intakes [32].

Who is more prone to B12 deficiency in American society?

What is the most common cause of vitamin B12 deficiency in older adults?

Abstract. Vitamin B12 deficiency is common among the elderly. Elderly people are particularly at risk of vitamin B12 deficiency because of the high prevalence of atrophic gastritis-associated food-cobalamin (vitamin B12) malabsorption, and the increasing prevalence of pernicious anaemia with advancing age.

What populations might be at risk for nutrient deficiency and may benefit from a multi vitamin mineral supplement?

People with certain medical conditions — such as celiac disease, cancer, Crohn's disease, alcoholism, hypothyroidism, and anorexia — are more likely to develop nutrient deficiencies, including B vitamins ( 16 , 17 , 18 , 19 , 20 ).

What causes vitamin deficiency?

Common medical causes of vitamin deficiency include: Alcoholic liver disease. Liver failure. Kidney disease.

Which of the following groups would be most likely to develop a thiamin deficiency?

Thiamin deficiency (causing beriberi and other problems) is most common among people whose diet mainly consists of white rice or highly processed carbohydrates in developing countries and among alcoholics.

Why is vitamin B12 deficiency common?

Even though the vitamin is found in many foods, B12 insufficiency and deficiency are relatively common. This is often due to limited dietary intake, malabsorption, certain medical conditions, or the use of B12-depleting medications ( 2 , 3 , 4 ).

Can B12 deficiency run in families?

It tends to run in families and is most common in people over 60. It affects women more than men. If you have another autoimmune disease, such as Addison's disease, you may be more likely to develop pernicious anaemia.

Why do you get B12 deficiency?

A vitamin B12 deficiency is most often caused by digestive system difficulties, which can occur if the body is unable to absorb B12 from foods and liquids. Most frequently this is due to a lack of intrinsic factor from the stomach or insufficient acid in the stomach.

What are the signs of B12 deficiency?

What are the deficiency diseases of vitamin B?

Vitamin B12 deficiencies can lead to megaloblastic anemia, a condition where the bone marrow produces large abnormally shaped red blood cells that do not function properly. Dementia, paranoia, depression, and behavioral changes can result from a vitamin B12 deficiency. Neurological damage sometimes cannot be reversed.

Who is most affected by vitamin A deficiency?

While deficiency is rare in developed countries, many people in developing countries do not get enough vitamin A. Those at highest risk of deficiency are pregnant women, breastfeeding mothers, infants and children. Cystic fibrosis and chronic diarrhea may also increase your risk of deficiency.

What are two main causes of vitamin deficiency diseases?

Nutrient deficiencies or diseases can be the result of poor nutritional intake, chronic health conditions, acute health conditions, medications, altered nutrient metabolism, or a combination of these factors, and can impact the levels of both macronutrients and micronutrients in the body.

What is vitamin B12 for?

Vitamin B12 is needed to form red blood cells and DNA. It is also a key player in the function and development of brain and nerve cells. Vitamin B12 binds to the protein in the foods we eat. In the stomach, hydrochloric acid and enzymes unbind vitamin B12 into its free form.

Which group of people is most vulnerable to inadequacy of one or more dietary nutrients?

A deficiency risk was most common in women 19–50 years (41%), and pregnant or breastfeeding women (47%). Dietary supplement non-users had the highest risk of any deficiency (40%), compared to users of full-spectrum multivitamin-multimineral supplements (14%) and other dietary supplement users (28%).

Why are children more susceptible to vitamin deficiencies adults?

Vitamin deficiencies affect all ages and frequently co-exist with mineral (zinc, iron, iodine) deficiencies. The groups most susceptible to vitamin deficiencies are pregnant and lactating women, and young children, because of their relatively high needs for these compounds and susceptibilities to their absence.

What conditions put patients at risk of nutrient deficiencies?

How common is B12 deficiency in elderly?

A deficiency in any vitamin can be catastrophic for health. But vitamin B12 deficiency stands out because a) it's very common — experts have estimated that up to 20% of older adults may be low in this vitamin — and b) it's often missed by doctors.

What is the most common reason that vitamin B12 deficiency occurs in older adults quizlet?

What is the most common reason that vitamin B12 deficiency, or at least compromised B12 status, occurs in older adults? The elderly have a higher incidence of bacterial overgrowth, which decreases secretion of hydrochloric acid.

Why are older people at increased risk for vitamin B12 deficiency quizlet?

Why are older people at increased risk for vitamin B-12 deficiency compared to younger people? As you age, your stomach produces less acid, which limits cleavage of vitamin B-12 from food. In addition, decreased production of intrinsic factor by the stomach limits vitamin B-12 absorption.

Who is most at risk for iron-deficiency anemia?
