# Find the height and weight percentiles at 18mo

Part I: Read through the following case study and answer the questions.

You have recently become a Registered Dietitian employed at a family practice clinic. One of your responsibilities is to weigh and measure patients and assess their growth.

Today, a 24-month old girl named Amanda comes to the clinic; she is 34” tall and weighs 33 lbs. Using the appropriate WH0 Growth Grids for Girls (link below), determine what percentile Amanda falls into for both height and weight. (NOTE: This may be an estimation; for example, it may fall between one or two of the standard growth curves. Remember that percentiles can go no higher than 100.)

Age: 18 months – Weight:28 lbs. Height: 32″12 months – Weight 23 lbs. Height 29.5″9 months – Weight 20 lbs. Height 27.5″

Find the height and weight percentiles at 18mo, 12mo, and 9 mo. Plot these measurements using age on the X axis and the weight percentile on the Y axis. On the same graph, plot the age (X-axis) and height percentile (Y-axis). Your graph will have 2 lines.

Submit your graph and, in 250-300 words, analyze Amanda’s growth and weight. For example, do the height and weight plots follow a similar patterns? Do they stay between the same percentiles, or are they different? What does this indicate? Finally, what is your advice to Amanda’s parents?
