Question
Emma is a 19 year old student. You gather the following anthropometric data on her:
Height 5'4"
Weight 110 lbs.
Wrist circumference 14.5 centimeters
Elbow breadth 1.5 inches
Utilizing the CDC growth chart for her age, calculate Emma's BMI and plot her age and BMI on the chart. What BMI percentile does she fall into and what classification does this put her in according to Box 6.1 on page 175 of your Lee text? (You only need to provide the percentile for this questions, you do not need to provide a copy of the growth chart)
Calculate Emma's frame size using her height to wrist circumference ratio. How does this frame size compare to her frame size based on the elbow breadth measurement?
What assumptions might you make about Emma's nutrition status based solely on this information?
What additional anthropometric data would you want to collect to have a more complete picture of her nutrition status?
s a BMI 30 kg/m, whichever is smaller Notice in Figure 6.8 that the 95th percentile curve exceeds a BMI of 30 kg/m beginning at approximately 18 years of age. The BMI of an adolescent is classified as obese when it is 30 kg/m2 even if it is less than the 95th percentile curve.12-14 Percentile Cut-Off Value <5th percentile 5th and< 85th percentile 85th and< 95th percentile 95th percentile or 30 kg/mt (whichever is smaller) Classification of BMI Underweight Healthy weight Overweight Obese
Box 6.1 Defining Overweight and Obesity in the Pediatric Population The body mass index-for-age percentile charts developed by the CDC and published in 2000 should be used for classifying body mass index (BMI) in children and adolescents age 2 years of age and older, as shown below.12-14 An example of the chart for females is shown in Figure 6.8 and the chart for males is in Appendix K. The charts are also available from the CDC's website (http: www.cdc.gov/growthcharts). Weight and stature should be carefully measured following the standardized methods outlined in this book, and recorded in the appropriate location in the table in the upper left-hand corner of the chart, along with the date and the subject's age to the nearest month. BMI should be accurately calculated to the nearest one-tenth (carried out one decimal point) and also recorded in the appropriate line of the table. Age should be plotted along the horizontal axis of the chart, and BMI should be plotted along the vertical axis. Draw a small circle on the chart where the lines representing these two values intersect. Check to make sure that the circle is at the correct point in reference to the two variables. A child or adolescent age 2 to 20 years having a BMI-for- age 85th percentile butExplanation / Answer
Height: 5'4" = 1.524 + 0.1016 = 1.3556 m
Weight: 110 lbs = 49.8952 kg
BMI: weight in kg / (height in metres)2 = 27.2 kg / m2
Percentile: 89%
She is Overweight, because if BMI >= 85% it indicates as overweight.
Wrist circumference: 14.5 cm= 5.708661 in
The body frame is small.
Explanation: women with height of 5'2" to 5'5": small if wrist size is less than 6'. Medium if wrist size is 6' to 6.25". Large if wrist size is over 6.25".
Nutritional status: Emma seams to be having small body frame and is Overweight. This means that he weight is more than her height. She might me taking junk foods and fatty foods which should be reduced or restricted. Strict diet should be followed to reduce weight.
Waist to hip ratio is the additional anthropometric measurement required here to have a more complete picture of her nutritional status.
