Abstract

Introduction: Blood pressure in children can be affected by a lot of factors such as environmental, cultural, social and genetic factors. This study aims at comparing Blood pressure in Shiraz (Iran) children with American standards and also to determine Blood pressure smoothed centiles on height in 6.5-11.5 elementary school children for the first time.

Method: Height, systolic Blood pressure and diastolic Blood pressure were measured with standard methods in 2270 elementary school children that were selected by multistage sampling. We produced Blood pressure percentiles on height percentiles and compared them with National High Blood Pressure Education Program results by using its suggested regression equation. Meanwhile, Blood pressure smoothed centiles on height were drawn by Healy- Rasbash-Yang method.

Results: The results of this study showed that Blood pressure levels in Shiraz children were lower than global standards. Then the measurements were adjusted for height, and no significant correlation found between either systolic Blood pressure or diastolic Blood pressure and age (r = -0.03 and p = 0.15 for systolic Blood pressure, r = -0.005 and p= 0.8 for diastolic Blood pressure).

Discussion: Due to significant differences between Blood pressure in Iran and American children, it is suggested to use local Blood pressure standards. And also it was decided to produce Blood pressure percentiles on height instead of age because it seems that it would lead to better evaluation for real hypertensive diagnosi
