Question 1

Which anthropometric measurement is most commonly used to assess central adiposity and cardiovascular risk?

Accepted Answer

Waist circumference

Answer

Waist circumference directly measures abdominal fat and is a stronger predictor of metabolic syndrome and cardiovascular risk than BMI alone.

Question 2

Which laboratory marker is used to assess long-term glycemic control over approximately 2-3 months?

Accepted Answer

Hemoglobin A1c (HbA1c)

Answer

HbA1c reflects average blood glucose levels over the lifespan of red blood cells (~2-3 months) and is the gold standard for monitoring diabetes management.

Question 3

In a nutritional assessment, what does a 24-hour dietary recall capture that a food frequency questionnaire (FFQ) does not?

Accepted Answer

Detailed quantitative intake on a specific day

Answer

A 24-hour recall collects precise quantitative data on all foods and beverages consumed in the previous 24 hours, capturing one day's actual intake in detail.

Question 4

Which visceral protein has the shortest half-life and is therefore most sensitive to acute changes in nutritional status?

Accepted Answer

Retinol-binding protein — half-life ~12 hours

Answer

Retinol-binding protein has the shortest half-life of approximately 12 hours, making it the most sensitive indicator of acute changes in nutritional status.

Question 5

The Malnutrition Universal Screening Tool (MUST) incorporates which three components to assess malnutrition risk?

Accepted Answer

BMI, unintentional weight loss, and acute disease effect

Answer

MUST scores BMI (0-2), percentage unintentional weight loss over 3-6 months (0-2), and acute disease effect (0 or 2), with total score guiding intervention.
