Blood pressure distribution in an Iranian adolescent population: "Tehran Lipid and Glucose study"

Significant hypertension in adolescence is defined according to Blood Pressure (BP) distribution among general population. The present study was conducted to determine the BP distribution in Iranian adolescents. In a population-based study held in Tehran, BP data for 2560 participants aged 10-17 years (1247 boys and 1313 girls) were collected. The 90th and 95th percentiles of systolic (SBP) and diastolic BP (DBP) were obtained for different age and height subgroups of boys and girls. While the 90th and 95th percentiles of SBP obtained in our study were generally lower than international guidelines, the corresponding percentiles of DBP were higher. Significant associations were found between BP and age, height, weight and BMI. According to our findings, it is necessary to prepare BP reference tables according to regional surveys.
