Objective: This study was aimed to determine the frequency of pre-hypertension and hypertension along with its association with inter-arm difference of blood pressure.Methodology: It was a cross sectional study conducted at Aziz Fatimah Medical and Dental College Faisalabad. Students of age ranged 19-21 years were enrolled by convenience sampling technique for screening of pre-hypertension and hypertension. Blood pressure was recorded from both arms by using sphygmomanometer and inter-arm differences were estimated. Mean±SD for continuous variables, frequency and percentages for categorical variables and chi square for association between pre-hypertension, hypertension and inter-arm difference was analyzed by SPSS 21.Results: Study comprised of 100 students with mean age 19.79±1.18 years. Of total 47% were females and 53% was male population. Mean systolic (p value =0.0002*) and diastolic (p value =0.000*) blood pressure of the two arms were significantly different. Of total population, 27% and 13% of population had pre-hypertension and hypertension respectively. Mean systolic inter-arm difference was significantly higher among the hypertensive subjects as compared to pre-hypertensive subjects, (p value =0.0001*). No significant difference was noted with respect to diastolic inter-arm difference (p value =0.93). Greater percentage of normotensive subjects have systolic inter-arm difference <10mmHg as compared to this most of the subjects with hypertension and pre-hypertension have systolic inter-arm difference of >15mmHg. Significant association between hypertension and systolic inter-arm difference was noted (p value =0.025)Conclusion: Pre-hypertension and hypertension is prevalent among young adults. High systolic inter-arm difference was significantly associated with pre-hypertension and hypertension.
Objectives: To explore the association between the body mass index (BMI) and inter arm difference (IAD) blood pressure and to understand how these factors influence blood pressure. Study Design: Cross-sectional study. Place and Duration of Study: Aziz Fatimah Medical and Dental College Faisalabad Pakistan, from Nov to Dec 2020. Methodology: Total 100 healthy medical students aged 19-21 years were included in the study. Height in meters and weight in kilograms were documented by stadiometer (ZT-100). BMI was assessed by Quetelet's index (BMI=weight in Kg/height in m2). Blood pressure was recorded simultaneously in both arms by the auscultatory method. Inter arm difference in blood pressure was estimated by calculating differences in diastolic and systolic pressures between the right and left arm. Results: Mean age of the participants was 19.83 ± 1.23 years. Significant difference was noted in systolic and diastolic interarm blood pressure among obese and non-obese groups (p-values <0.001). BMI was positively associated with diastolic and systolic inter-arm blood pressure (p-values <0.001). Conclusion: Body mass index is positively associated with inter arm difference in blood pressure, and both positively impact the blood pressure.
