Abstract text

Introduction: Traditional food of indigenous peoples in Yamal is not only a set of certain products, but also an integral element of nomadic peoples culture, source of prevention and treatment, important factor for increasing adaptation to Arctic conditions. Our study aimed to analyze impact of traditional nutrition on the mechanisms for preventing diseases of the circulatory system, depending on age, sex, residence area, nomadic or settled lifestyle, dynamics and monitoring of local fish consumption in 2012-18.


Methods: 1382 residents living in tundra (219), native settlements (796) and arrived population (367) of the Tazovsky Peninsula were interviewed. The amount of food consumed was estimated using an album of food and food portions. The blood pressure was measured by the Korotkov method, presence of arterial hypertension was established in accordance with the recommendations of RSC 2016. A model of increasing risk of hypertension in the studied population, based on logistic regression, was constructed, using a factor of local fish consumption.


Results: Prevalence of hypertension was revealed. Negative dynamics (26.6%-48.8%) was detected because of significant increase in prevalence of hypertension (χ2-34.1, p<0.001). The leading and modifiable risk factor for hypertension is violation of nutritional behavior – reduction in local fish consumption. We proved significant effect of local fish consumption on the development of hypertension (χ2=6.3, p<0.01, OR=2.1, 95% CI 1.1-4.5).


Conclusions: Reduced consumption of fish in indigenous population’s traditional diet in the Arctic zone leads to increase in carbohydrate intake and the development of hypertension.
