Regional differences in the reference blood pressure in young Indians.

ABSTRACT

This study compares the blood pressure (BP) in young population of North India and South India. Age, height and sex specific BP was estimated for 6320 North Indian subjects aged 7-18 years and compared with BP values of South Indian subjects. North Indian boys and girls had lower diastolic BP (DBP) with no difference in systolic BP (SBP) than South Indian boys and girls between 7-12 years. Between 13-18 years North Indian boys and girls had significantly higher SBP with no difference in DBP. The significant regional differences in BP distribution among young Indians suggest considering geographic location of the population in evaluating blood pressure.
