Q: A male patient has a waist circumference of 105 cm and a hip circumference of 100 cm. Calculate his waist-to-hip ratio.

$$Waist\text{-}to\text{-}hip\ ratio = \frac{105}{100} = 1.05$$

Q: A 40-year-old woman weighs 70 kg, is 1.7 meters tall, and has a physical activity (PA) value of 1.12. Calculate her Estimated Energy Requirement (EER) using the formula for adult females: $$EER = 354 - [6.91 \times age (y)] + PA \times [9.36 \times wt (kg) + 726 \times ht (m)].$$

$$EER = 354 - [6.91 \times 40] + 1.12 \times [9.36 \times 70 + 726 \times 1.7] = 354 - 276.4 + 1.12 \times [655.2 + 1234.2] = 77.6 + 1.12 \times 1889.4 = 77.6 + 2116.13 = 2193.73$$

Question 7

A 40-year-old woman weighs 70 kg, is 1.7 meters tall, and has a physical activity (PA) value of 1.12. Calculate her Estimated Energy Requirement (EER) using the formula for adult females: $$EER = 354 - [6.91 	imes age (y)] + PA 	imes [9.36 	imes wt (kg) + 726 	imes ht (m)].$$

Accepted Answer

$$EER = 354 - [6.91 	imes 40] + 1.12 	imes [9.36 	imes 70 + 726 	imes 1.7] = 354 - 276.4 + 1.12 	imes [655.2 + 1234.2] = 77.6 + 1.12 	imes 1889.4 = 77.6 + 2116.13 = 2193.73$$
