International research organization of NCD Risk Factor Collaboration conducted a comparison of the average growth performance of 18-year-olds in 1914 and 2014 and found that the population of the Earth over the last century increased by 11 cm.
The addition of the growth is observed both among men and among women. While women with an average growth in 164,4 cm is still equal to men, whose average height reaches 177,5 cm
In addition, the study revealed changes in growth in different Nations. If in 1914 the highest nation was the Swedes (171,9 cm), while in 2014 they spared the Dutch grown since then to an average of 182,5 cm (2.8 cm more than the Swedes). The highest on the planet women was the resident of Latvia with an average growth 169,8 see In 1914, this “title” also belonged to the Swedes (of 160.3 cm).
According to one of the authors James Bentham, this trend is a consequence of better nutrition, hygiene and healthcare all around the world. In his opinion, the growth of a person depends on the environment and affect the life expectancy and condition of the body in old age. However, Elio’s Riboli, colleague of Jeremy Bentham, notes the greater vulnerability high people cancer.
The opinion of Bentham is confirmed by the fact that the overall trend of increasing growth of earthlings have local exceptions. For example, the population of some African countries in recent times, on the contrary, was lower. Scientists see the reasons for this deterioration in the economic situation in the region since the early 80-ies, which forced people to starve and led to the decline of medicine.
