Abstract: Objective To investigate the relationship between fat mass index (FMI),fat free mass index (FFMI) and blood pressure in children and adolescents in order to provide evidence for early prevention and intervention for the cardiovascular disease. Method A total of 4 469 children and adolescents at 7~17 years old in Qingdao from national student physical fitness and health survey were selected in 2014.The index of height,weight,blood pressure and sebum thickness were measured to estimate body fat percentage (BF%) and to calculate FMI and FFMI by Changling Jinji and Brozek formula.The t-test and multivariate linear regression analysis were used to analyze the level of blood pressure with reference standard of blood pressure of children and adolescent in China. Results The sebaceous thickness,lower sebaceous thickness,abdominal sebum thickness,BMI,FMI,FFMI in the normal blood pressure group were lower than those in the high blood pressure group(P all<0.01).Multivariate analysis showed that sebum thickness of lower angle shoulder,FMI and FFMI were the influencing factors of systolic blood pressure,and sebum thickness of lower angle shoulder,FFMI were the influencing factors of diastolic blood pressure with significant difference. Conclusions FMI and FFMI can be used as a more appropriate predictor of hypertension than BMI in children and adolescents.It is the key to control BMI,FMI growth of children and adolescents to prevent the adult hypertension.
