The average height in Sierra Leone, Uganda and Rwanda has declined by as much as 5cm in recent decades, a new study suggests.
Researchers at Imperial College London used data from around the world to track the height of young adults between 1914 and 2014 in over 200 countries and territories.
According to the survey, the global trend has been an increase in height, but some countries in sub-Saharan Africa, North Africa and the Middle East have seen a decline in the past 30 or 40 years.
Lead researcher Prof Majid Ezzati of Imperial’s School of Public Health, warns the world of responsible nutrition to increase wellbeing.
“This confirms we urgently need to address children and adolescents’ environment and nutrition on a global scale, and ensure we’re giving the world’s children the best possible start in life.”
The study revealed that Scandinavia and the US produced the tallest men, the Netherlands, Belgium, Estonia and Latvia now top the rankings, with Dutch men measuring an average height of 182.5cm.
Latvia currently has the tallest women, averaging 170cm followed by women from the Netherlands, Estonia and the Czech Republic, according to the study in the journal eLife.
The shortest men in the world are from East Timor, with an average height of 160cm, and the shortest women are from Guatemala, averaging a height of 149cm.
South Korean women and Iranian men are significantly taller than they were 100 years ago but Americans have barely grown, according to a new study Tuesday that reflects nutritional and environmental factors.
The top 10 tallest countries are all on the European continent.
Children and teenagers who are well nourished, have better hygiene and healthcare tend to be taller; and tall people tend to live longer, be better educated and earn more.
