Question 1

Which of the following is a protein deficiency that primarily affects toddlers in developing nations and leads to a range of symptoms such as lethargy, irritability and thinning of hair?

Accepted Answer

Kwashiorkor is a type of protein deficiency commonly found in toddlers in developing nations. Symptoms include lethargy, irritability, thinning of hair, and a swollen belly. Micronutrients refer to essential vitamins and minerals needed in small amounts in the diet. Eczema is a skin condition unrelated to protein deficiency. Tuberculosis is a bacterial infection and not related to this type of deficiency.

Question 2

Children who do not eat a balanced diet with enough protein are _________.

Accepted Answer

Protein is essential for building and repairing tissues, including those in the immune system. Without enough protein, children may have a weaker immune system and be more susceptible to infections and diseases.

Question 3

Why do infants from developing countries lag behind in their growth compared to infants from developed countries?

Accepted Answer

D

Question 4

By the time infants in developing countries reach their first birthday, their height and weight is as low as the bottom ____ of infants of the same age in developed countries.

Accepted Answer

The answer of By the time infants in developing countries...

Question 5

You and your roommate are watching a documentary on developing countries and your roommate notices that children in developing countries seem to be small for their ages. What would you tell him about this situation?

Accepted Answer

This phenomenon, known as stunting, is often caused by a lack of adequate nutrition, specifically a deficiency in protein, in early childhood. Children who are stunted may experience long-term health consequences and may also have lower cognitive development.

Question 6

Your roommate's brother has a child who is 9 months old. He was watching a documentary concerning iodine deficiency. He was very concerned and was talking about what he could do to help his son. What did you tell your roommate to tell his brother?

Accepted Answer

Providing the child with iodised salt is a simple and effective way to prevent or correct iodine deficiency. Injections may be necessary in severe cases, but this is not the first line of action. Option C is false, as iodine deficiency can have serious consequences such as developmental delays and goiter. Option D is also false and not relevant to addressing the concern about iodine deficiency.

Question 7

For young children who lack iodine, what difficulties can be seen in their cognitive development?

Accepted Answer

Children who lack iodine can show IQ deficiencies of 10 to 15 points.

Question 8

Iron, zinc and vitamins A, B12, C and D are referred to as ____.

Accepted Answer

Iron, zinc, and vitamins A, B12, C, and D are considered micronutrients because they are required in smaller amounts compared to macronutrients (e.g. carbohydrates, proteins, and fats).

Question 9

Comparing the human brain at age two to the human brain at birth, it is clear that ____.

Accepted Answer

The answer of Comparing the human brain at age two...

Question 10

What is the solution to the dilemma of iodine deficiency in children?

Accepted Answer

Adding iodine to salt, also known as iodized salt, is the most cost-effective and efficient way to address iodine deficiency in children. It costs only a few cents per person per year and can be easily distributed and accessed by the population. Adding iodine to meat or the local drinking supply can be more costly and difficult to implement, while injecting iodine into children is not a sustainable or safe solution.

Question 11

In young children, a lack of iodine inhibits cognitive development, resulting in an estimated IQ deficiency of ____ points.

Accepted Answer

A lack of iodine in young children can inhibit cognitive development, resulting in an estimated IQ deficiency of 10-15 points.

Question 12

Infants in developing and developed countries grow at about the same rate from birth to six months. Why are they similar?

Accepted Answer

Breast milk is the primary source of nutrition for infants in both developed and developing countries, regardless of other differences in their environments or cultures.

Question 13

Approximately one-third of the world's population has a dietary deficiency of ____.

Accepted Answer

According to the World Health Organization, approximately one-third of the world's population has a dietary deficiency of iodine, which can lead to thyroid problems, mental impairment, and goiter. Salt is not typically deficient in the diet and excessive intake can actually be harmful. While iron deficiency is a common problem, it is not as prevalent as iodine deficiency. B-complex vitamins are also a common deficiency, but not as widespread as iodine.

Question 14

Protein deficiency not only limits the growth of children in developing countries, but also makes them vulnerable to ____.

Accepted Answer

Protein deficiency can weaken the immune system and make children susceptible to diseases such as infections and illness, leading to an increased risk of early death.

Question 15

How many neurons does the brain contain when the toddler is 2 years old?

Accepted Answer

The answer of How many neurons does the brain contain...

Question 16

According to the World Health Organization, what percentage of children worldwide has diets that are deficient in protein?

Accepted Answer

The World Health Organization estimates that around 25% of children worldwide have diets that are deficient in protein, which can lead to malnutrition and other health issues.

Question 17

Your sister is very concerned about your toddler nephew. When they were at the paediatrician's office, the doctor measured your nephew's head circumference and his head is not growing as quickly as his body. What should you tell your sister?

Accepted Answer

It is normal for a toddler's body to grow faster than their head during this stage of development. As long as there are no other concerning symptoms, there is likely no cause for alarm.

Question 18

What disease caused by a protein deficiency lowers the effectiveness of the immune system, making toddlers more vulnerable to disease and, over time, can lead to coma and death?

Accepted Answer

The disease described is Kwashiorkor, which is caused by a protein deficiency. Marasmus and Cachexia can also be caused by protein deficiency, but they do not specifically affect the immune system. Anaemia is a condition caused by a deficiency in iron, vitamin B12, or folic acid, and does not involve protein deficiency.

Question 19

Perhaps the most crucial micronutrient deficiency worldwide is ____.

Accepted Answer

Iodine deficiency is one of the most prevalent micronutrient deficiencies worldwide, affecting an estimated 2 billion people. Iodine is essential for the production of thyroid hormones, which play a critical role in normal growth and development, as well as in regulating metabolism. A lack of iodine can lead to a range of health problems, including goiter, intellectual disability, and cretinism.

Question 20

During toddlerhood, children do not need as much of this to maintain a constant body temperature.

Accepted Answer

Toddlers have a greater surface area to body weight ratio than adults, meaning they can lose heat more quickly. However, they also have a higher metabolic rate, which can generate heat. Therefore, toddlers do not need as much body fat as adults to maintain a constant body temperature.
