Study The Relationship Between Arterial Blood Pressure and Child Length During Period 6 -14 Years Old

Background: Vital signs are an objective assessment of the crucial physiological activities of a living organism. Aim: To assess the relationship between height components and both systolic and diastolic blood pressure in children aged 6 to 14 years. Patients and methods: This cross-sectional study was conducted at the Department of Pediatrics, Al-Azhar University Hospital – Assuit. A total of 200 children, both sexes, aged between 6 and 14 years who presented to the Outpatient Pediatrics Clinics were eligible for recruitment. Results: A total of 200 children aged between 6 and 14 years were included in the study. Body length ranged from 102–165 cm (mean ± SD: 132.2 ± 14.16), sitting length — measured as the vertical distance from the top of the head (vertex) to the seated surface while sitting upright — ranged from 45–84 cm (64.2 ± 9.41), and leg length 23–104 cm (68 ± 11.97). Systolic blood pressure ranged from 65–120 mmHg (94.1 ± 15.76), diastolic BP 40–80 mmHg (61.5 ± 10.26), and mean arterial pressure (MAP) 48–93 mmHg (72.3 ± 10.29). Total length showed significant positive correlations with systolic (r = 0.265, P < 0.001) and diastolic BP (r = 0.416, P < 0.001). Sitting length also correlated significantly with systolic (r = 0.243, P < 0.001) and diastolic BP (r = 0.298, P < 0.001). Leg length showed a non-significant correlation with systolic BP (r = 0.122, P = 0.084) but a significant correlation with diastolic BP (r = 0.258, P = 0.002). Conclusion: In children aged 6–14 years, height and sitting length showed positive correlations with both systolic and diastolic blood pressure. Leg length correlated positively only with diastolic blood pressure, with no significant link to systolic pressure.
