Question

From the perspective of human health, malnutrition is important because it... A. Causes the majority of birth defects B. Is the primary source of teratogens for most children C. is an important contributor to child mortality D. Is the second leading cause of death from emerging disease E. Increases the occurrence of infectious cancers

Short answer

C. is an important contributor to child mortality

Step-by-step solution

Understand Malnutrition

Malnutrition refers to deficiencies, excesses, or imbalances in a person's intake of energy and/or nutrients. It can lead to various health problems, particularly in children.

Analyze Each Option

Consider how each option relates to the impact of malnutrition on human health.

Evaluate Option A

While malnutrition can have diverse health impacts, it is not primarily known for causing the majority of birth defects. So option A is unlikely to be correct.

Evaluate Option B

Teratogens are agents that cause birth defects, but malnutrition is not primarily categorized as a source of teratogens. Thus, option B is not the best choice.

Evaluate Option C

Malnutrition significantly affects child mortality. It can weaken children's immune systems, making them more susceptible to infections and diseases, thus greatly contributing to child mortality.

Evaluate Option D

Emerging diseases refer to new infections that spread in a population for the first time. Malnutrition is not specifically linked as the second leading cause of death from such diseases.

Evaluate Option E

Malnutrition can compromise the immune system, potentially increasing susceptibility to infections, but it is not typically known for increasing the occurrence of infectious cancers.

Choose the Correct Option

Based on the evaluations, the most accurate option is C. Malnutrition is an important contributor to child mortality.

Key concepts

Child Mortality

Child mortality refers to the death of children under the age of 5. This is a critical issue linked closely to malnutrition. Malnutrition weakens a child's immune system, making them more vulnerable to infections and diseases such as pneumonia and diarrhea.
When children lack essential nutrients, their growth and development can be severely affected. This can lead to stunted physical growth and cognitive impairments.

• Malnutrition increases the risk of severe infections.
• It compromises physical and cognitive development.
• It is a major factor in child mortality rates globally.

By ensuring proper nutrition, we can help reduce child mortality and promote a healthier future for these children.

Human Health

Human health is significantly influenced by nutritional status. Malnutrition can present in different forms, such as undernutrition and overnutrition. Each of these forms can lead to various health complications.
Undernutrition results from inadequate intake of essential nutrients, leading to conditions like anemia, osteoporosis, and impaired immune function. Conversely, overnutrition, often related to excessive calorie consumption, can result in obesity, diabetes, and cardiovascular diseases.

• Balanced nutrition supports a strong immune system.
• Proper nutrient intake is crucial for preventing chronic diseases.
• Both undernutrition and overnutrition have severe health consequences.

Nutritional interventions and education are essential to improve overall human health and prevent diseases.

Nutrient Deficiency

Nutrient deficiency occurs when the body does not get enough vitamins and minerals necessary for proper functioning. This can be due to poor diet, malabsorption issues, or increased nutritional demands.
Common nutrient deficiencies include vitamin D, iron, and iodine deficiencies. Each of these can have specific health impacts, such as weakened bones, anemia, and thyroid dysfunction.

• Vitamin D deficiency can lead to bone diseases like rickets and osteoporosis.
• Iron deficiency is a leading cause of anemia, affecting energy and cognitive function.
• Iodine deficiency can lead to thyroid problems and developmental issues.

Detection and treatment of nutrient deficiencies are vital for maintaining good health and preventing related diseases.
