Sample MCQ and Answers on Public Health Nutrition

To demonstrate the scope and depth of MCQs in this ﬁeld, here are some carefully crafted

questions with detailed answers and explanations. These examples touch on nutritional

assessment methods, public health interventions, and policy considerations.

1. Which of the following is the most reliable indicator for assessing the

protein status of a population?

A) Serum albumin levels

B) Dietary recall data

C) Mid-upper arm circumference (MUAC)

D) Prevalence of kwashiorkor

Answer: D) Prevalence of kwashiorkor

Explanation: Kwashiorkor is a severe form of protein-energy malnutrition characterized

by edema, and its prevalence indicates protein deﬁciency in a population. While serum

albumin can be inﬂuenced by other factors like infection, and dietary recall may have

reporting errors, clinical signs like kwashiorkor provide direct evidence of protein

malnutrition.

2. The primary objective of the World Health Organization’s Global

Nutrition Targets 2025 is to:

A) Eliminate all forms of malnutrition worldwide

B) Reduce stunting and wasting among children under ﬁve

C) Promote vegetarian diets globally

D) Increase calorie consumption in adults

Answer: B) Reduce stunting and wasting among children under ﬁve

Explanation: WHO’s Global Nutrition Targets aim to reduce childhood stunting by 40%,

wasting to less than 5%, anemia in women of reproductive age, and low birth weight.

These goals focus on improving child nutrition and maternal health through evidence-

based interventions.

3. Which dietary assessment method is best suited for capturing habitual

dietary intake in large-scale nutrition surveys?

A) 24-hour dietary recall

B) Food frequency questionnaire (FFQ)

C) Direct observation

D) Biomarker analysis

Answer: B) Food frequency questionnaire (FFQ)

Explanation: FFQs are designed to assess usual intake over an extended period, making

them suitable for epidemiological studies and population surveys. While 24-hour recalls

provide detailed information on recent intake, they may not reﬂect habitual consumption

patterns.

4. What is the main cause of iodine deﬁciency disorders in populations?

A) Excessive consumption of goitrogens

B) Low iodine content in soil and water

C) High salt intake

D) Vitamin A deﬁciency

Answer: B) Low iodine content in soil and water

Explanation: Iodine deﬁciency is primarily due to insuﬃcient iodine in the environment,

especially in mountainous or ﬂood-prone regions where soil iodine is depleted. This leads

to disorders such as goiter and cretinism unless addressed through iodized salt programs.
