Abstract

Objective:

To present oscillometric blood pressure (BP) reference tables for Portuguese children and adolescents, and compare them with the available reference tables.

Objective:

Figure 1. Gender-specific percentiles for systolic and diastolic blood pressure at median height.

Design and method:

Data were collected from 15,049 healthy Portuguese children and adolescents (27% female), mean age 13.02 ± 2.05 years (range: 5–17 years) and body mass index (BMI) 19.22 ± 3.60 kg/m2. Three measures of BP and heart rate (HR) were obtained under standard conditions over the brachial artery with a clinically validated automatic sphygmomanometer (OMRON 705IT). Gender-specific percentiles for systolic (SBP) and diastolic (DBP) BP, accounting for age and height, were obtained and compared with the US reference tables (Fourth Report).

Results:

Gender-specific percentile tables, accounting for age and height, were obtained for the total cohort At median height, the 95th percentiles of SBP were higher in the portuguese cohort compared to the US BP reference values for children and adolescents (Fourth Report), particularly for ages up to 16 years, with age-specific differences ranging from 1mmHg to 7mmHg in girls and from -1mmHg to 8mmHg in boys (figure 1).

Conclusions:

The availability of national reference tables for BP in children and adolescents is necessary, as it would allow for a better blood pressure profile definition and optimized preventive strategies for these particular populations. The differences found in the portuguese percentiles compared to US reference values reinforce the need to adjust the reference tables to different pediatric specificities.
