Downloaded from 1 2 Objective: Till now no available blood pressure nomograms for children and adolescents in Egypt. 3 4 5 Methods and study design: A total of 60025 Egyptian children from birth to 19 years were enrolled in this 6 7 cross sectional randomized study from December 2015 to March 2017. They were selected from diverse 8 9 geographical districts in Egypt. Healthy children who fulfilled the inclusion criteria, which included good 10 11 nutritional history, the absence of fever or documented underlying disease at the time of examination, no 12 13 evidence of hemodynamically significant illness, no antihypertensive drugs or other chronic drug 14 15 For peer review only 16 administration, were included in the study. Body weight, recumbent length (for less than 24 months), and 17 18 height (from 2 years to 19 years), blood pressure were measured using standard mercury 19 20 sphygmomanometers. 21 22 Results: Blood pressure rises with age in both boys and girls. The 90th percentiles of SBP and DBP among 23 24 25 Egyptian children were different from other ethnic population (American and Turkish children) among both 26 27 sexes. Systolic and diastolic blood pressure showed a positive correlation with weight and height in both 28 29 sexes (P<0.001). 30 31 Conclusion: We assumed that normal BP curves should be utilized cautiously in childhood, and it is 32 33 recommended that every population should handle their own normal standard curves to define a measured http://bmjopen.bmj.com/ 34 35 36 blood pressure levels in children. These centiles increase our knowledge and awareness of normal blood 37 38 pressure among Egyptian children and adolescents. The percentiles will distinguish children and young 39 40 adolescents with increased blood pressure and will be of value to both medical practice and scientific 41 on September 29, 2021 by guest.
