Blood pressure and its correlates in the population of Multan, Pakistan.

In a randomly selected sample of 1579 individuals (male = 1334 and female = 245), aging from 14 to 65 years and representing all the socioeconomic groups of Multan, age (Yr), height (cm), weight (kg), BMI (kg/ml) and blood pressure (mmHg) were recorded. Height was measured on a Holtain portable stadiometer, weight on beam scale and blood pressure was recorded with sphygmomanometer as per auscultatory method. The correlation coefficient between different independent (age, height, weight and BMI) and dependent (SBP, DBP and MAP) parameters in male, female and total population were calculated and strong association between different parameters was observed (p < 0.001 or p < 0.05). The regression equations (simple and multiple) were worked out. The regression coefficient of different independent parameters with dependent parameters are higher in female except for height and age-weight and age-BMI had higher contribution in female as compared with that of male.
