Abstract:
Objective:To investigate the relationship between body fat percentage (BF%) and high blood pressure among adolescents in Shanghai, and to provide basis for early prevention and intervention of cardcovascular diseases.
Methods:By using stratified cluster sampling method, a total of 5 148 adolescent students in 16 schools from 16 districts of Shanghai were selected. Questionnaire survey and physical examination were performed. The bioelectrical impedance analysis (BIA) was used to measure body fat percentage. National Blood Pressure Reference for Chinese Han Children was used to define high blood pressure. And T test, chi-square test and Logistici regression were used to assess the relation between BF% with high blood pressure.
Results:The prevalence of high blood pressure in 5 148 junior middle school students in Shanghai was 10.98%, with girls (13.13%) higher than boys (8.99%)(χ 2=22.48, P<0.01). The average total body fat percentage of male students was (20.90±10.73)%, which decreased with age (linear trend variance is 10.04, P<0.01). The average total body fat percentage of girls was (25.14±8.03)%, which increased with age (linear trend variance is 69.23, P<0.01). After adjusted for age, diet, exercise and other influencing factors, the prevalence of hypertension showed an increasing trend with the increase of body fat percentage for both boys and girls. The risk of high blood pressure in boys with BF%≥P 90 was 12.43 times higher than that in boys with BF%
Conclusion:There was a positive correlation between body fat percentage and high blood pressure in adolescents. The prevalence of high blood pressure increased with the increase of body fat percentage, which was more obvious in boys.
