Predicting adult height given current height, age and growth plate measurement

Click For Summary

Discussion Overview

The discussion centers around predicting adult height based on current height, age, and growth plate measurements, with considerations of medical conditions such as Marfan syndrome. Participants explore both medical and statistical perspectives on height prediction.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant shares their current height and growth status based on X-ray results, indicating they are not halfway done growing.
  • Another participant suggests that the issue may be more medical than statistical, while also recommending checking regression models for predictions.
  • A participant emphasizes their lack of expertise and encourages looking into relevant literature and studies to inform predictions.
  • One participant mentions having Marfan syndrome, suggesting it may need to be factored into any height prediction.
  • Another participant proposes considering adjusted R² in the context of the individual's condition, referencing a source for further information.

Areas of Agreement / Disagreement

Participants express differing views on whether the prediction is primarily a medical or statistical issue, and there is no consensus on the best approach to take for height prediction.

Contextual Notes

The discussion highlights the complexity of predicting height, particularly with the influence of medical conditions like Marfan syndrome, and the potential limitations of statistical models in this context.

Who May Find This Useful

This discussion may be of interest to individuals dealing with growth prediction, medical professionals, and those researching statistical models in relation to height and growth conditions.

I went to see an orthopedic specialist this year, when I was 15 years and 5 months old. I am 5 ft, 11 1/4 in. The specialist looked at my then-recent X-rays and I was not even halfway done growing. (I'm pretty sure I scored a 2 out of 5.)

I am due for another X-ray sometime next year, at which point I may have a better idea of how quickly I am growing.

I think this may be more of a medical issue than a statistical one, tho you may want to check some regression models for prediction.
 
I just want to make it clear that I have no special training in that area, and
that I am just giving my opinion based on what you posted, so please don't
take what I said as an authoritative statement. Instead, I was suggesting you
could take a look at the literature, look for some studies that you believe best describes
your situation, and then maybe post the data here for us to suggest.

That's what I've been trying to do. Wish there was a Website I could input that data into. Also, I probably should have mentioned this but I have Marfan syndrome, which may eed to be factored into a prediction. Maybe I should just wait until my next ortho appt.
 
You might want to consider then R^2 adjusted for your syndrome; see the bottom of:

With the same caveat as in my 2nd post. Good Luck.

Edit: I thought it would be fair to give Pyrrhus credit for introducing me to adjusted R^2.
