In the Mifflin-St. Jeor equation, which two body measurements are included besides age?

• A. Weight and height
• B. Weight and age
• C. Height and age
• D. Weight and sex

Answer: (A)

The two measurements that describe body size in the Mifflin-St. Jeor equation, besides age, are weight and height. The equation uses weight (in kilograms) and height (in centimeters) to scale metabolic rate to how large a person’s body is. Height reflects lean body mass and organ size, while weight captures the total metabolic tissue. Age accounts for metabolic changes over time, and sex is included as a separate factor, but it’s not a body measurement. So the pair of body measurements besides age is weight and height.
