Exercise 141. According to the study narrative and Figure 1 in the Flannigan et al. (2014) study, does
the APLS UK formula under- or overestimate the weight of children younger than 1 year
of age? Provide a rationale for your answer.
It overestimates the weight of children younger than 1 year of age. The reason is the fact that
fig 1 indicates that there is a notable difference between the estimated weight using
two methods. Hence, the APLS UK formula mean is on the upper side.
2. Using the values a = 3.161 and b = 0.502 with the novel formula in Figure 1, what is the
predicted weight in kilograms (kg) for a child at 9 months of age? Show your
calculations.
For 9 months old child the weight is given as:
¿ 3.161+ 0.502 ( 9 )=7.679
The weight is 7.679 kg.
3. Using the values a = 3.161 and b = 0.502 with the novel formula in Figure 1, what is the
predicted weight in kilograms for a child at 2 months of age? Show your calculations.
A child aged 2 months will weigh:
¿ 3.161+ 0.502(2)=4.165
The weight with is 4.165 kilograms.
