Blood pressure in a Tehranian urban population of adolescents: "Tehran Lipid and Glucose Study"

Introduction: Many studies in children and adolescents have shown that high blood pressure in adults is closely associated with high blood pressure during juvenile ages. This study was conducted to determine distribution of blood pressure among Tehranian adolescents. Methods.: Data of 2575 participants aged 10-17 years (1254 boys and 1321 girls) in the cross-sectional phase of Tehran Lipid and Glucose Study (February 1999 to September 2001) were collected. The study used mean of two separate standardized blood pressure measurements in each individuals. Results: The mean Systolic blood pressure ranged from 100.2 ± 10.9 mmHg (12 years old) to 112.0 ± 11.7 mmHg 17 years old for boys and from 99.0 + 11.4 mmHg (11 years old) to 106.4 f 11.0 mmHg (17 years old) for girls. The corresponding values for mean diastolic blood pressure were 70.4 ± 9.9 mmHg (11 years old) to 73.1 ± 8.9 mmHg (17 years old) in boys and 67.0 ± 9.5 mmHg (12 years old) to 73.7 f 8.2 mmHg (17 years old) in girls. The mean SBP showed a rather steady increase with age in both genders while mean DBP showed a less increase with age. The SBP and DBP of boys and SBP of girls were predominantly correlated by height rather than age. Compared to girls, boys had higher SBP levels. The overall prevalences of significant hypertension and high normal state were 10.6% and 12.3% in boys and 12.3% and 12.9% in girls, respectively. Conclusion: Significant hypertension during adolescence is prevalent in Tehran. This finding requires further evaluation for causes and preventive measures.
