HIS THE INCREASE IN THE INCIDENCE OF TYPE 2 DIABETES IN YAKUTIA DUE TO A DECREASE IN COLD EXPOSURE OR DIETARY CHANGES?

Abstract

In Yakutia for 30 thousand years people live, and for centuries they were constantly fighting with the cold for survival [5, 6]. Situation began to change only in the second half of the twentieth century. In 20-ies of the last century a campaign for the reconstruction of traditional Yakut home began. As a result of the transition from balagan (yurts) to houses with stove heating, and then to centralized and gas heating, the temperature inside residential buildings has significantly increased. A fairly extensive literature has now accumulated linking rising residential temperatures with obesity-related morbidity. In order to determine the role of climate warming, an increase in the average temperature in the houses of the region, and changes in the diet on the incidence of type 2 diabetes, we built a multiple regression equation with 10 factors over 20 years (1994-2013). The following factors were included in the multiple regression model: the average annual temperature in Yakutsk, the average temperature of houses in the region during the heating period, the consumption of vegetables, fruits, sugar, proteins, fats, carbohydrates per year per person, and the daily calorie content of the diet. The conducted studies made it possible to find out that there are positive linear statistically significant pair correlations between the incidence of DM2 and the consumption of fruits and berries, the average housing temperature, the consumption of vegetables and melons, and the calorie content of the diet, but when analyzing multiple regression, the role of each factor in the development of DM2 turns out to be statistically unreliable, except the level of consumption of fruits and berries (at p > 0.05). It should be noted that a sharp increase in the incidence of DM2 in the population of Yakutia (including indigenous people) is associated with many factors, but the role of increased consumption of fruits and berries in its development should be considered causal, probably due to the lack of adaptation of the body of northerners to intake of large amounts of fructose, with a high level of fat intake.
