词汇: Height 词汇: 身高

It seems that these days it's the European nations who have the tallest men and women. Research carried out by over 800 scientists measuring height trends for different nationalities since 1914 has found that Dutch men and Latvian women now top the height charts. However, according to the study, it's Iranian men and South Korean women who have shot up the most – they have gained on average more than 16cm and 20cm respectively.

In the UK, the rate of growth for men and women has been the same – 11 cm – with the average male now standing at 178cm and the average female at 164cm , both 5cm shorter than the average Dutchman and Latvian female.

Surprisingly, US men and women have sunk right down in the rankings. While in 1914, they were ranked third tallest for men and fourth tallest for women, nowadays they are down to 27th and 42nd,and today it's Estonia who has the third tallest men and women. East Asia has seen the most gain in height – with people in China, Japan and South Korea much taller than they were 100 years ago. The survey found that the world's smallest men are in East Timor, 160cm, and smallest women, 150cm, are from Guatemala, 20cm smaller than Latvian women.

According to the authors of the study, based at Imperial College in London, genetics are not the sole factor in determining height variation among different nations, as Majid Ezzati, lead scientist of the project explained: "Genes don't change that fast and they don't vary that much across the world. So changes over time and variations across the world are largely environmental." Of critical importance were sanitation, healthcare and nutrition, he said, as well as the mother's health and diet during pregnancy.

Other surprising findings, relating to how height impacts on people's health and income, have been revealed. For example, tall people can expect enhanced longevity and they are less likely to suffer from heart disease. Tall people are also likely to earn more! According to research by Exeter University, a British man who is 7.5 cm shorter than his counterpart will earn £1,500 less!It might be time to invest in a pair of shoes with heels!
