Key result
Absolute 10 cm height ranges enable practical BP percentile evaluation in children and adolescents.
Why the study?
Height is a determinant for evaluating blood pressure in children and adolescents, but appropriate height ranges for BP measurement have not been established.
Cross-Sectional (n=3,013)
Yes
Height ranges of 10 cm are suitable for establishing blood pressure percentiles in children and adolescents for use in epidemiological and educational contexts.
May aid pediatric BP assessment by height; cross-sectional data leave prospective validation and outcome links open.
Background: Evaluating blood pressure (BP) is one element for diagnosing and preventing disease in student populations. The objectives of this research were to a) verify the range of height for measuring BP adjusted for student populations and b) propose percentiles for evaluating BP based on height.Methods: A cross-sectional study was carried out with 3,013 students. Weight, height, and diastolic (DBP) and systolic (SBP) blood pressure were evaluated. Body Mass Index (BMI) was calculated. Height ranges of 5 and 10 cm were generated.Results: R2 values for height ranges of 5 cm consisted of [normotensive: DBP (R2=10 to 13%) and SBP (R2=14 to 20%) and for hypertensive: DBP (R2=0.07 to 15%) and SBP (R2=29 to 32%)]. For height ranges of 10cm, values included: [normotensive: DBP (R2=10 to 15%) and SBP (R2=15 to 21%) and for hypertensive: DBP (R2= 0.07 to 16%) and SBP (R2=29 to 35%)]. For 5 cm height ranges, diferences occurred between both sexes for DBP (in 5 height ranges from 123 to 148 cm and 158 to 168 cm) and for the SBP ( in 6 height ranges from 128 to 148 cm and from 158 to 168 cm). In the 10 cm categories, diferences appeared in DBP (from 138 to 148 cm) and in the SBP (from 158 to 168 cm).Conclusion: Height is a determinant for evaluating blood pressure, and height ranges of 10 cm are more suitable for children and adolescents. The proposed percentiles based on height ranges allowed assessment of the DBP and SBP suggest their use in epidemiological and educational contexts.

Cossio‐Bolaños et al. (2020) conducted a cross-sectional in Blood pressure evaluation (n=3,013). Absolute height ranges (10 cm intervals) vs. Absolute height ranges (5 cm intervals) was evaluated on Relationship between height and blood pressure categories (R2 values). Absolute height ranges of 10 cm are a practical determinant for evaluating blood pressure in children and adolescents, enabling the development of specific percentiles for clinical assessment.
