“Height Gap” With Parents Determines Age of Puberty

“The opposite is also true: ‘short’ children don’t reach puberty until later than the societal average because their bodies are giving them extra time to grow in order to reach a parent’s height.”

‘The findings of the study show that a ‘tall’ child would reach puberty earlier than his/her peers and a ‘short’ child would hit puberty little later than the average pubertal age.’


The researchers said that while there is a wide variation for what is considered a “normal” age for puberty to begin, scientists have not been able to validate the prevalent assumption that genetics plays a major role in determining when an individual will begin puberty.

BGU’s observational, retrospective study focused on groups of Israeli and Polish children. The Israeli group of 110 boys and 60 girls had been referred to an endocrinology clinic in southern Israel from 2004 to 2015 because of a “normal” but below average or short stature, or early or late puberty. The Polish group of 162 girls and 173 boys attended Warsaw elementary schools. Researchers followed the boys from ages 8 to 18, and the girls until age 17.

“A child who hits puberty earlier than his peers, but at a time consistent with a parental height gap model, should be considered ‘healthy’,” Dr. Limony says. “We believe having the ability to determine normal ranges more accurately will reduce the need for unnecessary diagnostic procedures and help doctors better explain the emergence of early- or late-onset puberty to concerned parents.”
