Using the Mifflin-St. Jeor equation, what is the basal energy requirement for a 65-year-old woman who is 170 cm tall and weighs 62 kg?

To calculate the basal energy requirement (BEE) using the Mifflin-St. Jeor equation for a woman, the formula is:

BEE = (10 x weight in kg) + (6.25 x height in cm) - (5 x age in years) - 161

Substituting the woman's details into the equation:

• Weight: 62 kg

• Height: 170 cm

• Age: 65 years

The calculation would proceed as follows:

1. Calculate the weight component: 10 x 62 = 620

2. Calculate the height component: 6.25 x 170 = 1062.5

3. Calculate the age component: 5 x 65 = 325

4. Putting it all together: 620 + 1062.5 - 325 - 161 = 1196.5 kcal/day

When rounding the result, it is typical to arrive at approximately 1,200 kcal/day. Therefore, this value reflects the basal energy expenditure accurately for the individual based on her identified characteristics.

This understanding of the equation and the components confirms the answer to be consistent with the data from the question, aligning with option A as the basal energy requirement
