Question

Calculate the energy and protein requirements for a four-year-old female who weighs 38 pounds, is 39 inches tall, and is considered active.

EER for Boys 3 through 8 years

EER = 88.5 −(61.9 × age [y]) + PA × (26.7 × weight [kg] + 903 × height [m]) + 20 kcal

EER for Girls 3 through 8 Years

EER = 135.3 −(30.8 × age [y]) + PA × (10.0 × weight [kg] + 934 × height [m]) + 20 kcal

PA = 1.00 if PAL is estimated to be ≥ 1.0 < 1.4 (sedentary)

PA = 1.13 if PAL is estimated to be ≥ 1.4 < 1.6 (low active)

PA = 1.26 if PAL is estimated to be ≥ 1.6 < 1.9 (active)

PA = 1.42 if PAL is estimated to be ≥ 1.9 < 2.5 (very active)

Answer 1

According to the given question

Girl weight is 38 lbs

At first convert weight lbs to kg

Then 38 lbs= 17.24 kg39

Girl height (tall) is 39 inches

Convert height in inches to meters 39 inches = .99 m

PA=1.26EER=1404.396

The girl was considered as an active

So the PA = 1.26 if PAL is estimated to be ≥ 1.6 < 1.9 (active)

PA = 1.26

Then 19.05 kg (.95) = 16.378

So the girl needs 16.378 g of protein per day
