Obesity prevalence rate, depending on various criteria in the average age population of urban and rural residents of the Siberian region

Aim. To assess the obesity prevalence rate, depending on various criteria in the average age population of urban and rural residents of the Siberian region.

Material and methods. 1600 people permanently residing in Kemerovo and Kemerovo region were examined. All household members aged 35-70 years were invited to the study. The average age of respondents was 54,3±9,88 years. Obesity was determined according to the World Health Organization’s classification by body mass index (BMI), as well as waist circumference (WC), WC/hip circumference (HC) ratio, visceral fat rating (VFR) and visceral obesity index (VOI). Statistical data processing was carried out using Statistica 6.0 software.

Results. According to traditional criteria (by BMI), obesity prevalence was 45,5% in women and 35,9% in men (p=0,0004), among urban and rural residents — 38,8% and 51,5%, respectively (p<0,0000). Obesity prevalence among women ranged from 20,9% (VFR) to 76,5% (WC), among men — from 33,4% (VIO) to 73,9% (WC/HC ratio). It was noted that in BMI <25 kg/m² group obesity prevalence was 38,5% (WC/HC ratio), 15,0% (WC), 1,6% (VFR), 15,0% (VOI).

Conclusion. Depending on the criteria used, obesity prevalence among women ranged from 20,9% to 76,5%, among men — from 33,4% to 73,9%. Obesity prevalence among the urban population was 26,5% — 73,5%, among the rural population — from 41,9% to 78,4%. Obesity prevalence among women was significantly higher when using such obesity criteria as BMI, WC and VIO, and when applying the VFR level, this condition was diagnosed more often among men than women. Rural residents statistically significantly more often had obesity by all studied criteria, except for the WC/HC ratio.
