Key result
Blood pressure-to-height ratios demonstrated high accuracy in identifying elevated blood pressure in adolescents aged 11-15 years, with area under the curve values ranging from 0.906 to 0.981.

Does blood pressure-to-height ratio accurately screen for elevated blood pressure in adolescents aged 11-15 years?
Effect estimate: AUC 0.906 to 0.981
Blood pressure-to-height ratios demonstrate high diagnostic accuracy for identifying pre-hypertension and hypertension in adolescents aged 11-15 years.
BPHR may support elevated BP screening in adolescents; hypothesis-generating and requires prospective validation before practice change.
Objective: This study aims to validate measures of blood pressure-to-height ratios (BPHR) inscreening for elevated blood pressure (EBP) in a sample of the Egyptian adolescence aged 11-15 years.Methods: A cross sectional study was conducted on a sample of 1707 students aged11-15 years. Elevated blood pressure was defined according to the international gold standarddefinition. Systolic and diastolic BPHR (SBPHR and DBPHR) were calculated for boys andgirls, and their ability to identify EBP has been determined by the area under the curve of thereceiver operator characteristic curves. Sex-specific optimal cut-off points were determinedalong the curve, and their sensitivity, specificity, positive and negative predictive values(PPVs, and NPVs), and positive and negative likelihood ratios (LR+, and LR-) wereestimated. Results: The accuracy of SBPHR and DBPHR in diagnosing EBP in both sexesranged from 0.906 to 0.981. For diagnosing systolic and diastolic pre-hypertension (pre-HTN), the optimal cut-off points were: 0.69, 0.44 in boys, and 0.71, 0.46 in girls respectively.For diagnosing systolic and diastolic hypertension (HTN), the corresponding values were0.75, 0.49, and 0.75, 0.50 respectively. These determined cut-off points revealed highsensitivity (0.88-1.00), moderate to high specificity (0.77-0.95), high NPVs (0.99-1.00), lowPPVs (0.15-0.38), and variable likelihood ratio values (LR+: 3.8-20.0, and LR-: 0.0-.36.0).Conclusion: Blood pressure-to-height ratios are considered of high accuracy inidentifying pre-HTN and HTN in the Egyptian adolescents aged 11-15 years. Further researchis needed for examining the performance of the BPHR in other age groups, in high riskadolescents, and for examining the performance of modified ratios.

A 2018 study conducted a cross-sectional in Elevated blood pressure (n=1,707). Blood pressure-to-height ratio (BPHR) vs. International gold standard definition for elevated blood pressure was evaluated on Accuracy of systolic and diastolic blood pressure-to-height ratios in diagnosing elevated blood pressure (AUC 0.906 to 0.981). Blood pressure-to-height ratios demonstrated high accuracy in identifying elevated blood pressure in adolescents aged 11-15 years, with area under the curve values ranging from 0.906 to 0.981.
