Wiki 英文原文
Humans grow fastest
(other than in the womb) as infants and toddlers,
rapidly declining from a
maximum at birth to roughly age 2, tapering to a
slowly declining rate, and
then during the pubertal growth spurt, a rapid
rise to a second maxima (at
around 11–12 years for female, and 13–14 years
for male), followed by a
steady decline to zero. On average, female growth
velocity trails off to
zero at about 15 or 16 years, whereas the male curve
continues for
approximately 3 more years, going to zero at about 18–20.
These are also
critical periods where stressors such as malnutrition (or
even severe child
neglect) have the greatest effect
