Abstract
Purpose. To evaluate the effect of the changed living conditions during the last decade, the prevalence of obesity as a risk factor for cardiovascular disease among residents of Mountain Shoria. Materials and methods. During the periods since 1998 till 2002 and since 2012 till 2015 in field conditions by continuous method we examined 1215 and 774 inhabitants correspondingly in the outlying hard-to-reach villages of Mountain Shoria. About half of them was represented by indigenous inhabitants - Shors, the other half by more than 95% was represented by Russians. The examination included: clinical examination, measurement of height, body mass, waist circumference (WC), hip circumference (HC), body mass index, WC/HC index. Obesity diagnosis was made in accordance with WHO criteria (1997). Results. During all the examination periods women of non-indigenous nationality revealed obesity more often (3.9% of obesity cases among Shor women, 31.3% cases among non-Shor women over the period since 1998 till 2002 (р=0.0001), 7.3% of obesity among indigenous female inhabitants and 31.4% among non-indigenous women over the period since 2012 till 2015 (р=0.0001)). Over the last 15 years a number of individuals with obesity and overweight has significantly increased: the percentage of men with obesity (over the period since 1998 till 2002 - 0.8% of Shor and 2.4% of non-Shor men had BMI≥30 kg/m2 (р=0.072), as compared to 2012-2015 period - 7.3% of Shor and 27% of non-Shor men had obesity (р=0.00001). Among Shor women the percentage of obese individuals increased significantly at the age of 40-49, 60-69 and over 70 years old. In representatives of male indigenous population the number of obese individuals increased significantly at the age of 40-49 years old, in non-Shor men - at the age of 18-29, and 30-39 years old.
