Abstract:
Objective:To understand the relationship between the main body components and blood pressure in adolescents and to understand the association between major body components and blood pressure in adolescents provides a basis for reducing the risk of hypertension.
Methods:A total of 366 middle school students in Tianjin aged 12-15 with the normal intelligence and no serious disease, willing to participate in the research were selected. Inbody 520 human body composition analyzer was used to analyze their body composition. Systolic blood pressure diastolic pressure curve fit for the dependent variable selection, the optimal model of the selection criteria for goodness of fit value maximum and the minimum AIC value.
Results:The percentage of body fat of girls was higher than that of boys(t=-4.73, P<0.01). The systolic blood pressure pulse pressure difference of liposuction body weight was lower than that of boys(t=8.68, 2.38, 2.37, P<0.05). The systolic and diastolic blood pressure of the mixed obesity group was significantly higher than that of the normal body type group(F=6.59, 4.78, P<0.01). In the six fitting models, except for the secondary model between body fat percentage and diastolic blood pressure, the AIC value and R2 value of boys were not statistically significant, the other models were statistically significant(P<0.05). There was no statistical significance in the three-time model between body fat weight and systolic blood pressure, the linear and logarithmic model between body fat percentage and diastolic blood pressure, the linear, logarithmic, quadratic, cubic, AIC value and R2 value of the combined model, but the other models had statistical significance(P<0.05).Besides, the quadratic and power equations between body weight and systolic and diastolic blood pressure of female students meet the minimum of AIC value and the maximum of corrected goodness of fit R2, the percentage of body fat, body weight and systolic and diastolic blood pressure of male and female students meet the minimum of AIC value and the maximum of corrected goodness of fit R2.
Conclusion:Compared with boys, adolescent girls are more prone to obesity and other diseases, and obesity is closely related to blood pressure. It is suggested that the effective control of the growth rate of body fat percentage is conducive to improving physical fitness, preventing and reducing the risk of hypertension, and promoting the healthy growth of adolescents.
