Growth Trajectory Analysis for E.: Four Points Over Twelve Months, a Length Lying Down Against a Height Standing, Weight Crossing Two Percentile Lines Before Length Moved and a Loss of 4 Grams a Day
The Series First
Table 1
E.'s Growth Measurements
| Age | Date | Weight (kg) | Length or height (cm) | How measured | Chart used |
|---|---|---|---|---|---|
| 12 months | 11 months ago | 10.4 | 76.0 | Length, lying, infant board | WHO |
| 15 months | 9 months ago | 11.1 | 79.5 | Length, lying, infant board | WHO |
| 18 months | 6 months ago | 12.0 | 82.0 | Length, lying, infant board | WHO |
| 24 months | today | 11.2 | 85.5 | Height, standing, stadiometer | CDC |
Note. Note. All weights undressed on the same clinic scale. The 24-month visit is the first standing height.
The Spacing Between Points
Three points in the first six months of the series, then a six-month gap with no measurement, then today's. A great deal could have happened in that gap, and the analysis cannot say when the weight began to fall within it.
Lying Down Against Standing Up
The first three are lengths, taken lying flat; today's is a height, taken standing. A child is about 0.7 cm shorter standing than lying. The recommended practice in the United States is to use the WHO growth standards from birth to 24 months and the CDC charts from 2 years, which coincides with the switch from length to height (Grummer-Strawn et al., 2010). So today's point sits on a different chart, measured a different way. To compare like with like, adding 0.7 cm to today's height gives an estimated length of about 86.2 cm.
Which Curve Moved First
Weight: on the WHO chart, E. was near the 75th percentile at 12, 15 and 18 months. Today, 11.2 kg at 24 months falls near the 25th percentile on the CDC chart. E. has crossed two major percentile lines downward.
Length: near the 50th percentile at 12 to 18 months; today's estimated length of 86.2 cm sits close to the 40th to 50th percentile. Length has barely moved.
Weight fell first while length held. In poor nutrition or malabsorption, weight usually falls first and length follows months later; in a constitutionally small child or familial short stature, length and weight track down together and stay in proportion.
Rate Stated in Units
From 18 to 24 months, weight went from 12.0 to 11.2 kg, a loss of 800 g over about 183 days, roughly 4 g per day. A child of this age would be expected to gain, on average, around 5 to 8 g per day. The difference between an expected gain and a measured loss is about 10 g per day of missing growth.
What the Trajectory Suggests
Weight falling across two percentile lines while length holds, with months of loose stools and a distended abdomen on examination, suggests a problem with intake or absorption. Celiac disease is a leading candidate in a toddler who started gluten-containing foods around a year of age. Other possibilities include inadequate intake, cow's milk protein intolerance, cystic fibrosis and chronic infection.
The Point That Would Settle It
A single extra weight between 18 and 24 months would show when the fall began. The family's daycare records a weight at 21 months for its own health form; parent A will bring it. More useful still: a repeat weight and length in four weeks, taken the same way, with the first test results. Screening tests ordered today: tissue transglutaminase IgA with total IgA, complete blood count, ferritin and a basic metabolic panel.
What Was Told to the Family
Parent A was shown the chart with the two weight lines crossed and the length holding steady, and was told that this pattern usually means E. is not taking in or absorbing enough, rather than being a small child. Parent B received the same explanation by phone. Both were asked not to remove gluten from E.'s diet before the blood test, since doing so can make the test falsely negative.

PA 534 Week 4 instructions, in plain terms
The growth analysis asks you to judge a series of measurements before you judge the child. Lay out every point with its date, how it was measured and which chart it was plotted on. Comment on the spacing between points, since long gaps hide when a change began. The instructions expect you to handle the switch from length lying down to height standing at two years, and the matching switch from WHO to CDC charts in the United States. Then compare the weight curve with the length curve and say which moved first, because that order separates a nutritional problem from a small but healthy child. A rate in units per day is required, not only a percentile shift. Close with what the trajectory suggests, what single measurement would settle the timing and what the family was told.
How this PA 534 Week 4 example is built
A table opens the paper with four rows: 10.4, 11.1 and 12.0 kg by lying length on the WHO chart at 12, 15 and 18 months, then 11.2 kg by standing height on the CDC chart at 24 months, all on the same undressed scale. The spacing section notes that the fall happened somewhere in a six-month blank. The measurement section adds 0.7 cm to the 85.5 cm standing height so length can be compared, citing the chart guidance (Grummer-Strawn et al., 2010). Weight is shown dropping from near the 75th to near the 25th percentile while length stays near the 40th to 50th. The rate section works out 800 g lost over about 183 days, roughly 4 g a day, against an expected gain of 5 to 8 g. A suggestion section raises celiac disease and other causes of malabsorption. The final sections ask for the daycare's 21-month weight, order screening tests and record keeping gluten in the diet until testing.
PA 534 Week 4 rubric: what full points look like
Grading on this analysis begins with the series itself. A paper that jumps straight to a diagnosis without listing each point's method and chart gives up the largest share of points. Next, faculty check whether the length-to-height change and the chart switch were handled, because ignoring them can manufacture a fall that never happened. The comparison of weight and length, with a clear statement of which moved first, carries a large portion of credit. Stating the change as a rate in grams per day, compared with an expected gain, is graded separately from percentiles. Reasoning about causes earns marks when it follows from the pattern rather than from the history alone. Naming the measurement or test that would settle the timing, and recording what was told to the family, fill out the rubric, with APA mechanics last.
PA 534 Week 4 help from the desk
The most common error is to compare a standing height at 24 months directly with lying lengths from earlier visits and announce a drop in stature. Another is to report percentiles only, leaving the reader to guess how fast the child is losing ground. Some drafts also treat a long gap between measurements as if the change happened evenly. If your case gives you a different child, for example an infant crossing percentiles on a breastfed diet or a school-age child gaining too fast, send the measurements, dates and charts from your section; a custom analysis would test the series first, correct for any change in measuring method, compare the curves and state a rate in units. If your faculty want z-scores rather than percentiles, the analysis would be written in z-scores throughout.

PA 534 Week 4 questions, answered
The case gives me percentiles but not the raw measurements. Is that enough?
It is workable and the limitation is worth stating outright. Percentiles compress two things into one figure, so a change between them can come from the measurement or from where the child sits on a steep part of the reference. Say what you can read from the series you were given, and name what the raw values would have added.
Two of the measurements look wrong. Do I use them?
Use them and say why you doubt them. A weight that falls two kilograms and returns a month later is more likely a recording fault than a real event, and an analysis that drops it without saying so has edited the data. Naming the suspect point, giving the reason, and reading the series both with and without it is what earns the marks.
Do I have to say what is causing the pattern?
Rarely, and reaching for a cause is a common overstep. Most instructions stop at describing the pattern and naming what would be asked next, since a series of measurements cannot by itself identify a reason. Where a section does ask, the expected answer sets out two or three possibilities and says which measurement would separate them.
Where can I find a free PA 534 Week 4 sample paper?
The complete PA 534 Week 4 growth trajectory analysis, with four measurements, a chart switch at 24 months and a loss of about 4 g a day, is on this page.
Why does the PA 534 Week 4 sample add 0.7 cm to the 24-month height?
A child measures about 0.7 cm shorter standing than lying, so the sample converts the first standing height to an estimated length before comparing it with earlier lengths.
