Hypertension is the most important preventable risk factor for premature death worldwide. It increases the risk of ischemic heart disease, strokes, peripheral vascular disease, and other cardiovascular diseases, including heart failure, aortic aneurysms, diffuse atherosclerosis, and pulmonary embolism. In childhood, hypertension can be determined according to a table adjusted for height, age and gender . A graphic representation of pediatric hypertension was published in 1987 , and no graphic updates have been published since then. The objective of this study was to update the graphic representation of pediatric hypertension.
We used a computerized calculation method to develop high-resolution graphics containing curves with 5,841 points each, to depict the main percentiles associated with high blood pressure for boys from 1 to 17 years old in the 50th percentile of height. Each point represents the calculation of the polynomial equation that includes the statistical processing of the last Report on Blood Pressure . We also analyzed the effect of height on blood pressure in the 5th to 95th percentile range. Statistical functions generated by computerized program were used.
The adjustment of systolic BP for height is of little significance, and the updated graphic can be used to diagnose high systolic blood pressure for boys. Clinical studies are necessary to determine the systolic BP percentile that better represents clinically significant hypertension.
