Blood pressure distribution in a school age population of Quetta, Pakistan.
Standardized measurements of blood pressure, height and weight were obtained in 8-11 years old children, attending school in Quetta, Balochistan, Pakistan. The sample consisted of 427 individuals (219 boys and 208 girls). The blood pressure was measured by auscultatory method. To calculate the body mass index (BMI), the weight (kg) of each subject was divided by the square of the subject's height. Association between various variables and blood pressure was judged through correlation coefficient. The net and joint effect of selected variables on blood pressure variability was calculated using simple/multiple regression. The correlation coefficients with that of systolic blood pressure were 0.365, 0.427 and 0.341 whereas these were 0.397, 0.430 and 0.320 for diastolic blood pressure. Height had a regression coefficient of 0.475 mmHg/cm with systolic pressure and 0.419 mmHg/cm with diastolic blood pressure. Weight had a regression coefficient of 0.878 mmHg/kg and 0.717 mmHg/kg with systolic and diastolic pressure respectively whereas BMI had a regression coefficient of 2.35 mmHg/BMI unit with systolic pressure and 1.79 mmHg/BMI unit with diastolic blood pressure.
