For centuries Inuit children in Greenland, Canada, and Alaska have been observed as small. But recently they have begun to grow a lot.
»During the last couple of years people have noticed that Greenlandic boys and girls are getting taller compared to older generations. These common observations have now been scientifically proved,« says Marius Kløvgaard, MD and one of the scientists behind a newly published study of growth of Greenlandic children.
Previous studies of growth of the indigenous Inuit people of Greenland, Canada and Alaska has characterized them as shorter but with the same weight as European or continental US citizens. Yet, this specific growth pattern was no longer found in the new study of growth of Greenlandic children conducted by researchers from University of Southern Denmark, which has just been published in the scientific journal Acta Paediatrica.
»We evaluated the growth of 279 healthy Greenlandic boys and girls aged 6-10 years and found that at puberty, Greenlandic children are now as tall as children in Denmark,« says Marius Kløvgaard.
As a part of the study the research group has also conducted specific growth charts for children in Greenland that can be used for monitoring growth and thrive. Growth charts for Greenlandic children have never been published before.
Genes and obese mothers
The fact that the growth of Greenlandic children is no longer stunted has several explanations.
»Many people in Greenland have one or more ancestors of Scandinavian origin so genetic admixture is quite common. That might to some extent explain why children in Greenland have a similar growth pattern to children in Denmark,« says Marius Kløvgaard.
Another important finding is a high number of obese mothers.
»It is well-known that obese mothers get large babies, and it seems like these larges babies keep on being large during their childhood,« says Marius Kløvgaard.
Healthy children
Furthermore, in a recent study, the research group found, that children in Greenland are as healthy as children in Denmark. Actually, children in Greenland have fewer visits to the doctors than Danish children.
»Chronic diseases might hamper growth. But improvements in health and nutrition have reduced these kind of problems,« says Marius Kløvgaard.
