Dynamics of frequency of overweight and obesity children of young school age in the Tyumen region

BACKGROUND: Over the past decades, the growth of overweight and obesity among the population, especially significant in children, is registered everywhere. To assess the dynamics of the obesity epidemic and to monitor the effectiveness of preventive interventions in the regions, it is recommended that monitoring be carried out in the regions to ensure regular measurement of body weight.

AIMS: to assess the dynamics of the frequency of overweight and obesity in children of primary school age in the Tyumen region.

METHODS: a survey of children aged 8–11 years old residing in the Tyumen region in 2008 (n=390) and in 2017 (n=468) was conducted. The choice of territories in 2008 was carried out by the cluster method in 2008 and in 2017. The studies were conducted by expeditionary method with the departure of a team of doctors in the territory with the measurement of height and body weight and determination of the body mass index (BMI). The results were evaluated according to the SDS BMI guidelines. To compare the frequency of occurrence of qualitative features, the chi-square test (χ²) was used, to compare samples by quantitative characteristics, Student's t-criterion was used. The critical level of significance (p) was checked for statistical hypotheses to be 0.05.

RESULTS: In 2017, in the Tyumen region, an increase in the frequency of obesity in children of primary school age is 2.4 times higher than in 2008 (6.7% in 2008, 15.8% in 2017), in boys as in girls. Overweight and obesity are more often diagnosed in boys in 2017 (40.0%). Girls 8–11 years in 2017 compared with 2008 increased the frequency of both obesity and overweight.

CONCLUSION: In 2017, in the Tyumen region, an increase in the frequency of obesity in children of primary school age is 2.4 times higher than in 2008 (6.7% in 2008, 15.8% in 2017), as in boys, and for girls. Overweight and obesity are more often diagnosed in boys in 2017 (40.0%). Girls 8–11 years in 2017 compared with 2008 increased the frequency of both obesity and overweight.
