Early puberty spurt leads to a final height shorter than genetically determined?

As we all know, East Asian teenagers are facing with early puberty problems and their growths ceases to grow earlier than those in the last century.
So I am wondering if their early puberty spurts are influencing their final heights negatively and they can't grow up to final heights that their genes determine them to grow up to, like a boy should have grown until he is 180cm tall but due to his early puberty spurt, he can only end up with being 175cm or even shorter.

Yes, this is called precocious puberty in extreme cases. It's what happened to me and shave 6-8 inches off my adult height.

Yes that happens. I wonder which leads to a shorter height, early puberty vs delayed puberty

What? 6-8 inches.. I dunno how to estimate one's adult height but was your adult height estimated by accurate medical equipments or just your self-assertation? But I think the reason why early puberty spurt reduces one's potiential of growing up to final height is that it deprives you of part of growth time.

IMO either they can lead to the same final height or the former leads to a shorter height. Delayed puberty doesn't deprive you of part of growth time while early puberty does. But early puberty or delayed one is also determined by genes in some cases but genes can't explain why East Asian children are proner and proner to early puberties.

Black Americans start puberty earlier than Asians and are still taller. Why do you care so much about Asian puberty are you trying to find a reason why you're short?

My final adult height was predicted using medical tools, midparental height, and growth charts. But yes, precocious puberty is known to massively decrease your adult height without medical intervention (by about 22 cm). Here’s a study about it where patients were given treatment: https://pubmed.ncbi.nlm.nih.gov/11600530/

Does precocious puberty specifically effect your legs? If you measured correctly you must have one of the highest sitting heights for a 170cm guy. Guys with that sitting height are usually 15-20cm taller than you.

That’s a great question. I found a study here that seems to suggest that: https://pubmed.ncbi.nlm.nih.gov/6234747/

I believe trunk growth actually prefaces leg growth in puberty, so that would explain things.

How to estimate the exact loss amount of precocious patients' growths? By medical tools or growth chart(like if your actual age is 6 y.o but your bone age is 8 y.o, then you will lose 2 yrs of your whole growth time?)
