Background. Various anthropometric and instrumental methods are used to assess the correspondence between height and body weight of a person. Aim. Carrying out a comparative assessment of the results of anthropometric indicators and bioimpedance analysis among men and women fitness center visitors. Material and methods. A cross-sectional study of 58 men and 62 women was carried out. Participants underwent standard anthropometry (measurement of height with a stadiometer; body weight with an electronic scale; measurement of waist circumference and hip circumference with a centimeter tape) and bioimpedancemetry. Statistical processing was carried out by non-parametric methods: to study the relationship between the phenomena, the Spearman rank correlation coefficient was used, the differences in the average indicators were calculated by the Student's t-test, relative indicators by the Pearson 2 test, the differences were considered statistically significant at p 0.05. Results. Correlation analysis of the main calculated anthropometric and bioimpedance parameters established a strong relationship between body mass index and adipose tissue content (r=0.87). According to the data of bioimpedance analysis in the group of men, there was a significant predominance of muscle mass over fat, both in normal and overweight (p 0.0001). In the course of a comparative assessment of body mass index and bioimpedance analysis indicators, it was found that the use of body mass index is more often associated with overdiagnosis of overweight (p=0.0067). In the group of women, bioimpedancemetry analysis showed the predominance of muscle tissue over adipose tissue only with a normal body mass index, with overweight, the predominance of adipose tissue was found (p 0.0001). According to the results of bioimpedancemetry, the frequency of the norm decreased by 1.5 times compared with the body mass index (p=0.0017), the proportion of obesity increased by 4 times (p=0.0017) and the proportion of overweight almost 1.4 times. Conclusion. A comprehensive assessment of the body composition by bioimpedancemetry in men established the predominance of muscle mass over fat, which made it possible to reduce the frequency of overdiagnosis of excess body weight by 2 times; in women, body mass index was associated with underdiagnosis of overweight.
Background: Numerous studies have demonstrated a steadily growing trend in the prevalence of obesity around the world. The objective of this study was to assess obesity incidence rates among various age groups of the population of the Voronezh Region in 2010–2017. Materials and methods: We used official data of the Voronezh Regional Information Fund, Registration Form No. 12 of the Russian Federal State Statistics Service, as well as outpatient cards and medical histories of 685 adults and 269 adolescents. Results: We established that the number of obese adults prevailed. The study period of 2010–2017 was characterized by a steady increase in the incidence and prevalence rates of obesity across all age groups of the population: we observed a 1.5, 2.6 and 4.5-fold rise of the incidence rates in children, adolescents and adults, respectively; the percent increase in the prevalence rates was slightly lower and amounted to 34.51% in children, 70.09% in adolescents, and 146.50% in adults. The highest obesity rates were registered among adolescents: 5.02% of them were obese and the study of a random sample confirmed the official statistics. At the same time, the results of the random obesity study in adults demonstrated a tenfold excess of the registered rate. Ranking of the territory of the Voronezh Region by obesity prevalence rates and the analysis of long-term average rates of increase in overall morbidity over the study period showed uneven distribution of obesity by administrative districts of the region in all population groups. Conclusions: The study demonstrated a pronounced upward trend in the incidence of obesity in all population groups of the Voronezh Region and underreporting of this pathology in the adult population of the region. Both findings indicate the need for immediate evidence-based actions aimed at managing the incidence based on data on the actual prevalence of the pathology, identifying the leading risk factors, adjusting diet and physical activity of various population groups, and assessing the efficiency of preventive measures.
Relevance Obesity has a major impact on the health and well-being of the population, and the prevention of overweight and obesity is a public health priority in many countries around the world.Purpose: was to study the prevalence of obesity among the adult population of the Voronezh region for the period 1996 – 2017, a comparative assessment of the structure of eating behavior in people with normal weight and overweight/obesity.Methods. The research material was data the annual form No. 12 of Rosstat for 1996 through 2017. In order to study eating disorders, 150 people aged from 20 to 61 years were surveyed using the Dutch questionnaire. The main types of eating behavior among the respondents were determined. Ideal weight was calculated by Brock's field formula (1891), the upper limit of normal body weight was considered ideal weight plus 15% ideal weight. Statistical data processing was performed using Microsoft Excel 2007.Results. The study on the prevalence of obesity was conducted among the adult population of the Voronezh region for the period 1996-2017. The Prevalence of obesity over the period studied has increased by 8 times, the average annual growth rate over the last 4 years was 30,04%. The study of the types of food behavior in respondents with normal and overweight / obesity showed that in most cases the respondents observed pathological types (most often mixed and external). A comparative assessment of the types of eating behavior did not show any significant differences between the groups.Conclusions. The increase in the prevalence of obesity, the high average annual growth rate indicates the increased impact of risk factors on the formation of obesity and the ineffectiveness of the strategy and tactics of dealing with this pathology. The absence of significant differences in the structure of eating behavior does not allow us to consider it a risk factor for obesity.
