ABSTRACT
Objective:
To explore the distribution characteristics of brachial-ankle pulse wave velocity (BaPWV) in adolescents.Methods:
Cross sectional survey research.A total of 1 607 adolescents aged 12-17 years from 5 middle schools in the Haidian District, Beijing from June 2020 to May 2021 were enrolled for measuring their blood pressure, weight, height and the body mass index (BMI), including 782 males and 825 females.BaPWV was measured using an arteriosclerosis detector.They were divided by the age, sex and obesity.Differences of measurement data among multiple groups were compared by one-way ANOVA, followed by the LSD test, and those between groups were compared by the two-sample t-test.The correlation between BaPWV and other indexes was assessed by the Pearson correlation analysis.Results:
The median level of BaPWV in adolescents aged 12-17 years increased with age, which was 982.50 cm/s in adolescents aged 12 years, and maximum 1 113.50 cm/s those aged 17 years.BaPWV in adolescents aged 12-17 years was positively correlated with age ( r=0.936, P=0.006). Subgrouped by the sex, the median BaPWV of male and female adolescents aged 12 years was 962.25 cm/s and 997.50 cm/s, respectively, which reached 1 122.50 cm/s and 1 096.00 cm/s in those aged 17 years, respectively.BaPWV of male and female adolescents was positively correlated with the age ( r=0.903, P=0.014; r=0.945, P=0.004). In male adolescents, BaPWV was positively correlated the systolic and diastolic blood pressure, age, weight, height, BMI( r=0.308, P<0.001; r=0.289, P<0.001; r=0.478, P<0.001; r=0.190, P<0.001; r=0.315, P<0.001; r=0.109, P=0.002). In female adolescents, BaPWV also was positively correlated the systolic and diastolic blood pressure, age, weight, height, BMI( r=0.340, P<0.001; r=0.285, P<0.001; r=0.379, P<0.001; r=0.115, P=0.001; r=0.170, P=0.001; r=0.097, P=0.014). In the overall population, BaPWV was statistically significant between the obese and normal groups ( t=-3.428, P=0.001). No significant difference in BaPWV between male and female adolescents aged 12-13 years was identified ( t=0.123, P=0.902 ), but it was significantly lower in female adolescents aged 14-15 years and 16-17 years than those of age-matched males( t=2.315, P=0.021; t=2.152, P=0.032).Conclusions:
The median BaPWV level in adolescents aged 12-17 years, increases with the age.Systolic blood pressure, diastolic blood pressure, body weight, BMI, age and height are positively correlated with BaPWV in adolescents.Obesity can increase the stiffness of blood vessels, which is influenced by the sex.
