Dutch, Latvians world’s tallest; Pinoys among shortest
NEW YORK – The Philippines ranked second with the shortest female population in the world, next to Guatemala at an average of 4-foot-11 (149.4 centimeters), according to a study, which analyzed a century’s worth of height data from 200 countries.
Other countries with the shortest female population are Bangladesh, Nepal, East Timor, Madagascar, Laos, the Marshall Islands, India and Indonesia.
The shortest male population is in East Timor, at an average of 5-foot-3 (160 centimeters). It is followed by Yemen, Laos, Madagascar, Malawi, Nepal, Rwanda, the Marshall Islands, the Philippines and Mauritania.
Results of the study were released Monday in the journal eLife. If you want to see a tall population of men, go to the Netherlands. Tall women? Latvia.
And in the United States, which lags behind dozens of other countries in height, the average for adults stopped increasing about 20 years ago.
National height averages are useful as an indicator of nutrition, health care,
environment and general health that people have experienced from the womb through adolescence, said Majid Ezzati of Imperial College London, who led the research. Genes also influence height.
The researchers calculated average height for 18- yearolds, roughly the age when people stop growing. They drew on more than 1,400 studies that covered more than 18.6 million adults who reached that age between 1914 and 2014.
Experts said the results generally agree with what others have reported before.
The tallest men in the new analysis were Dutch, with an average height of about six feet (182.5 centimeters). The next nine tallest countries for men were Belgium, Estonia, Latvia, Denmark, Bosnia-Herzegovina, Croatia, Serbia, Iceland and the Czech Republic.
Latvia topped the list for women, with an average height of 5-foot-6 (170 centimeters). Rounding out the top 10 were the Netherlands, Estonia, the Czech Republic, Serbia, Slovakia, Denmark, Lithuania, Belarus and Ukraine.
Over the century-long span of the study, the biggest gains appeared in South Korean women and Iranian men, who added eight inches (20.2 centimeters) and six inches (16.5 centimeters), respectively.
There was little change in South Asia and some subSaharan African countries.
In the US, men gained about two inches ( 6 centimeters) over the century, and about two inches (5 centimeters) for women. The nation is now the 37th tallest for men and 42nd for women, researchers said.
The analysis estimated that average height for US 18-yearolds maxed out at about 5-foot10 (177.5 centimeters) for men in 1996, and at about 5-foot-5 (164 centimeters) for women in 1988. Since then height has stalled but not decreased significantly, said James Bentham of Imperial College London, a study author.
Most Western countries, including the Netherlands, also have hit a plateau, although the US reached it early, researchers said.
The researchers did not investigate the causes of the US stagnation. But John Komlos, a visiting professor of economics at Duke University in Durham, North Carolina, said there could be several reasons. He did not participate in the new study but has previously studied height.
