Height variation is known to be determined by both genetic and environmental factors, but a systematic description of how their influences differ by sex, age and global regions is lacking.
The proportion of height variation explained by shared environmental factors was greatest in early childhood, but these effects remained present until early adulthood. Accordingly, the relative genetic contribution increased with age and was greatest in adolescence up to 0. Comparing geographic-cultural regions Europe, North-America and Australia and East-Asia , genetic variance was greatest in North-America and Australia and lowest in East-Asia, but the relative proportion of genetic variation was roughly similar across these regions.
Our findings provide further insights into height variation during childhood and adolescence in populations representing different ethnicities and exposed to different environments. Human height is a classic anthropometric quantitative trait for its ease of measurement, approximately normal distribution and relative stability in adulthood and thus has been the target of extensive research across many fields of science.
The study of height has a long standing tradition in genetics; in fact, the field of quantitative genetics was born out of studies of human height in the late 19 th and early 20 th centuries. Later on, Pearson and Lee 2 presented correlations of height between relatives, also providing evidence for the inheritance of height.
