ABSTRACT

Objective To investigate the status and the relationship between obesity and high blood pressure in children and adolescents in Tianjin, and to provide a reference for the development of targeted prevention and control measures for high blood pressure in children and adolescents. Methods In September 2019, a stratified cluster sampling method was used to select 30 403 children and adolescents aged 7-17 from 94 primary and secondary schools in 16 districts in Tianjin. Height, weight and blood pressure were measured by standard methods. SPSS 24.0 was used for χ2 test, variance analysis and binary logistic regression. Results The detection rate of overweight in children and adolescents in Tianjin was 17.28%, including 19.32% in boys and 15.07% in girls. The detection rate of obesity in children and adolescents in Tianjin was 22.79%, including 27.20% in boys and 18.01% in girls. The detection rate of high blood pressure in children and adolescents in Tianjin was 20.88%, including 20.98% in boys and 20.77% in girls. The detection rates of high blood pressure in the normal BMI group, overweight group and obesity group were 14.03%, 23.41% and 36.95%, respectively, and the difference was statistically significant (P<0.001). Compared to the normal BMI group, overweight and obesity were risk factors for high blood pressure in children and adolescents (OR=1.872, 95% CI1.735~2.021; OR=3.598, 95% CI3.366~3.827). Conclusion Overweight and obesity were important influencing factors for high blood pressure in children and adolescents aged 7-17 years. Controlling overweight and obesity is an important means to effectively cope with high blood pressure.
