Canadians have grown taller, but they’re not measuring up as high as they once did compared to other countries.
When it comes to males, Canada slipped from having the world’s fifth tallest men (5’6″ on average) in 1914 to 27th (with a height of 5’8″) a century later.
That’s the finding from a global survey, published in the journal eLife. The researchers calculated average height for 18 year olds, roughly the age when people stop growing. They drew on more than 1,400 studies that covered more than 18.6 million adults in 200 countries who reached that age between 1914 and 2014.
Over the course of that period, Canadian women fell from sixth tallest to 40th.
So where do the tallest people live? That honour goes to the Europeans. The top countries for height were all in Europe in 2014.
Dutch men (at 6 feet) and Latvian women (5’7″) tower above all the rest. If you’re into tall people, here’s where else you should go:
Top 10 countries with the tallest men (in 2014)
- The Netherlands
- Czech Republic
Top 10 countries with the tallest women (in 2014)
- The Netherlands
- Czech Republic
The shortest men (5’3″) can be found in the Southeast Asian nation of East Timor. The smallest women live in Guatemala. They had a four-inch growth spurt over the past 100 years, but still fall one inch short of five feet.
The largest jump in height appeared in South Korean women and Iranian men, who added 8 inches over the century-long span of the study.
In some Sub-Saharan countries (such as Rwanda, Sierra Leone and Uganda), the average height has actually shrunk.
“People from different countries grow to different heights. This may be partly due to genetics, but most differences in height between countries have other causes,” the study explained, citing sanitation and nutrition as potential factors.
“For example, children and adolescents who are malnourished, or who suffer from serious diseases, will generally be shorter as adults.”
Height in the U.S. has remained stagnant for about 20 years. The country lags behind dozens of others in height, which maxed out at 5’10” for men in 1996 and 5’5″ for women in 1988.
The researchers didn’t investigate the causes of the U.S. stagnation but John Komlos, a North Carolina professor who’s studied height, said there could be several reasons for it:
- lack of health insurance
- shortfalls in medical and prenatal care
- underweight and preterm babies from teenage pregnancies
- and a rise in obesity, which leads to earlier puberty and so stoppage of growth
In terms of where we sit on the obesity scale, the study puts the average body mass index of Canadian 18-year-old women in 2014 at 26.7. That’s considered to be in the “overweight” range. Canadian men’s average BMI comes in a touch higher, at 27.4.
Other researchers, however, cautioned this year against using BMI to measure health, saying “the data shows there are tens of millions of people who are overweight and obese and are perfectly healthy.”
Those behind the research hope their findings can help improve conditions around the globe.
The height advantage
The study points out “taller people generally live longer, are less likely to suffer from heart disease and stroke, and taller women and their children are less likely to have complications during and after birth.”
Other research has also shown that taller people may also see greater success at school and make more money.
On the downside, they’re also apparently more likely to develop some cancers.
