Key result
Age- and height-specific 50th, 90th, 95th, and 99th percentiles of systolic and diastolic blood pressures were established for boys and girls aged 6 to 18 years in Yazd using 10-cm height intervals.
Why the study?
Pediatric hypertension is a major cause of morbidity and mortality, requiring percentile-based blood pressure reference charts to examine hypertension in clinical settings.
Cross-Sectional (n=1,035)
This study provides new normative age-, sex-, and height-based systolic and diastolic blood pressure reference charts for Iranian children and adolescents to aid in the clinical diagnosis of pediatric hypertension.
BACKGROUND: Pediatric hypertension is the main cause of morbidity and mortality in pediatric populations. PURPOSE: To examine pediatric hypertension in a clinical setting, we used the percentile rank approach and defined hypertension as that above the 95th percentile. METHODS: The present study was linked to the a national analytical cross-sectional community-based Iranian Children and Adolescents' Psychiatric Disorders (IRCAP) survey. The survey was nationwide and funded by the National Institute of Medical Research Development. The IRCAP survey included 31,000 children and adolescents aged 6-18 years in all 31 Iran provinces. The current study included 1,035 children and adolescents and linked the data of the risk factors of cardiovascular disease only in Yazd province via random cluster sampling. RESULTS: Of the total participants, 456 (44.1%) were male and 579 (55.9%) were female. The mean age was 11.2±3.8 years (11.7±3.7 years for males, 11.0±3.6 years for females), while mean height was 146±20.0 cm overall, 147.2±22.0 cm for males, and 144.6±17.0 cm for females (P=0.009). The blood pressure distributions and percentiles were evaluated. CONCLUSION: Here we determined age- and height-specific 50th, 90th, 95th, and 99th percentiles of systolic and diastolic blood pressures in Yazd boys and girls using 10-cm height intervals.

Ahmadi et al. (2020) conducted a cross-sectional in Pediatric hypertension (n=1,035). Blood pressure measurement was evaluated on 50th, 90th, 95th, and 99th percentiles of systolic and diastolic blood pressures based on age, sex, and 10-cm height intervals. Age- and height-specific 50th, 90th, 95th, and 99th percentiles of systolic and diastolic blood pressures were established for boys and girls aged 6 to 18 years in Yazd using 10-cm height intervals.
