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

Edit Post

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.

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.

Quote from: ReadRothbard on December 05, 2021, 08:55:13 PMMy 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/
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?)

Thx. I think actual age can't eventually make sense and your bone age was prematured cuz of your precocious puberty.

Bone age is the best index that can be used as a medical tool to estimate your final height while your age can't.
The reason why I made my question is that I'm wondering if children and adolescents in one country are facing with early puberty problems, will their average heights be under the expectations in the future for next generations?

By the way, back then you said you were 5'6".
My growth is kinda weird but true. I ended up growing around my 16 y.o and prior to the end, I achieved three-centimeter growth all of a sudden for unknown reasons and then ended up growth until now. Seems like my growth is normal and my puberty spurt was not excessive early.

You must be able to remember the age where you ceased to grow and you will never grow after that age if you measure yourself accurately. Once your growth plates are closed then you will never grow taller, which is the saddest part of the whole story.

Quote from: ReadRothbard on December 20, 2021, 08:44:59 PMI largely agree, but there are some exceptions. Glucosamine sulfate will help add between 1-3 cm, but it's mostly the result of preserving morning height via preventing spinal decompression.
You gotta keep exercises that can decompress your spine combined with Glucosamine pills on a daily basis to achieve more than 0.33mm on the height according to the researches about Glucosamine sulfate pills. BTW take a noon break on a bed can have the same effect LOL, and no need to buy pills.
