Abstract

Objective To investigate body composition and serum uric acid level in children aged 8 to 11 years, as well as the differences among different age, sex and body mass index (BMI) groups, and to analyze the correlation between serum uric acid level and various indicators of body composition. Methods From April to December 2020, 306 children aged 8 to 11 who took physical examination in Nutrition Department of Taiyuan Maternal and Child Health Hospital were selected as study subjects. Height and weight of the participants were measured, body composition and serum uric acid level were tested. Then the correlation between body composition and serum uric acid level was analyzed. Results Boys had higher BMI than girls (t=2.253, P<0.05), but there was no significant difference in other body composition indicators between boys and girls (P＞0.05). The consistency of BMI and PBF when diagnosing obesity was higher in girls (Kappa=0.642), which was lower in boys (Kappa=0.438). The consistency of BMI and PBF was highest in 9-year-old boys group (Kappa=0.669) and 11-year-old girls group (Kappa=0.761). Person correlation analysis showed that serum uric acid level was positively correlated with all indicators of body composition. BMI had the most significant correlation with blood uric acid among boys(r=0.579, P<0.001). Among girls, BMI was the highly associated with serum uric acid(r=0.706, P<0.001), followed by the body fat content(r=0.705, P<0.001).Mutivariate linear regression analysis showed that BMI had the greatest effect on the serum uric acid level among all body composition indicators for children aged 8 to 11 years(P<0.05). Conclusions The physical condition of children aged 8 to 11 years in Taiyuan is close to that of the whole country. There is a high consistency between PBF and BMI when screening for obesity in 8- to 11-year-old children. Body composition indicators are related to serum uric acid level, so it is essential to pay more attention to the prevention of early hyperuricemia for children with high BMI.
