The relationship of family income, family size, age and circumferences with blood pressure in the female students of the Bahauddin Zakariya University, Multan, Pakistan

Abstract

In a randomly selected sample of 600 female students of the Bahauddin Zakariya University, Multan, Pakistan, belonging to different socioeconomic groups, age, family income and family size were recorded and measurements were made of arm, waist, neck and total circumferences, systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP). The correlation coefficients between different independent (age, family income, family size, arm, waist, neck and total circumference) and dependent variables (SBP, DBP and MAP) showed that age had a strong association (p < 0.001) with all types of blood pressure, whereas the correlation coefficient of family income and family size was significant with SBP (p < 0.05) and non-significant with DBP and MAP. Moreover, all the circumferences had strong relationship (p 0.05 at least) with blood pressure. The regression coefficients of age were highly significant for SBP, DBP and MAP, whereas these were non-significant (p > 0.05) for family income and family size. The regression coefficients for arm and waist were significant (p < 0.05), whereas these were highly significant (p < 0.01 at least) for neck and total circumferences. The neck had a 0.46 mm Hg/cm with SBP, 0.41 mm Hg/cm for DBP and 0.44 Hg/cm for MAP, and these were highest among the circumferences.
