Sample growth chart for use with American boys from birth to age 36 months. A growth chart is used by pediatricians and other health care providers to follow a child's growth over time. Growth charts have been constructed by observing the growth of large numbers of healthy children over time.
The typical age of legal majority is 18 years in most contexts, although the definition of majority may vary by legal rights and country. Human adulthood encompasses psychological adult development. Definitions of adulthood are often inconsistent and contradictory; an adolescent may be biologically an adult and display adult behavior but still ...
Further, estimated stunting at 2 years attributed to fetal growth restriction and preterm birth in 2011 was 33% in all developing countries and 41% in South Asia. [20] Restricted pre- and postnatal growth are in turn important determinants of short adult height, [28] increasing the likelihood of the next generation experiencing stunted growth. [29]
The average female growth speed trails off to zero at about 15 or 16 years, whereas the average male curve continues for approximately 3 more years, going to zero at about 18−19, although there is limited research to suggest minor height growth after the age of 19 in males. [16]
Peak height velocity (PHV) occurs at the average age of 11 years for girls and at the average age of 13 years for boys. [29] While there is no exact age for the culmination of bone maturity, modern research suggests a range of between 15-17 years for bone maturity in boys and 14-16 years for girls.
Zeng was born on 26 June 1964 in Yuanjiang, Hunan, to a poor farming family, as the youngest of four children, [a] growing up in Nanzui Town by Muping Lake. Her parents Zeng Xianmao and Yu Xuemei [b] were 163 cm (5 ft 4.2 in) and 156 cm (5 ft 1.4 in) respectively, with all her siblings being in within similar height range, with a brother being measured at 158 cm (5 ft 2 in) at age 18.

Maximal adult height is achieved at an average age of 15 years for an average female and 18 years for an average male. Potential fertility (sometimes termed nubility ) usually precedes completion of growth by 1–2 years in females and 3–4 years in males.
When treated with GH, a severely deficient child will begin to grow faster within months. In the first year of treatment, the rate of growth may increase from half as fast as other children are growing to twice as fast (e.g., from 1 inch a year to 4 inches, or 2.5 cm to 10).
