Subtle changes in traditional lifestyle of native ethnic groups in the Yamalo-Nenets region have brought the first-ever cases of obesity. Until now, fatness has not existed in these population groups, but scientists say there has been a marked change.
Alexey Titovsky, regional director for science and innovation, said: 'It never happened before that the small local indigenous peoples of the north suffered from obesity. It is a nonsensical modern problem. Now even a predisposition to obesity is being noticed.'
Changes have seen the intake of venison and river fish cut by half, he said. 'Over the past few years the diet has changed considerably, and people living in the tundra started eating so-called chemically processed products.'
