The future Alert of Inter-arm blood pressure difference Among young healthy population: A Cross-sectional Study

Abstract

Background: More than 100 years ago, the difference in blood pressure (BP) between arms was first reported. Recent studies have shown that different blood pressure between the right and left arm leads to cardiovascular events. The aim of the present study was to establish of an inter-arm blood pressure difference (IAD) and the dominant hands effect on the elevation blood pressure among young healthy population.Methods: This was a cross-sectional study using quantitative method for both data collection and data analysis and carried out at the Sulaimanyah governorate Kurdistan Region, Iraq among a young, healthy population. Data were expressed as percentages of individuals with systolic IAD and diastolic IAD and mean (± standard deviation) for the inter-arm difference in systolic blood pressure and diastolic blood pressure (DBP). To evaluate the association between IAD and age, BMI, heart rate, systolic BP, and diastolic BP Pearson’s correlation test was used. The Chi-square test was used to compare the prevalence inter-arm difference category between groups.Results: Three thousand and thirty volunteers participated in our study. The sIABP was equal in 163 of 3030 persons (5.37%), dIABP was equal in 222 out of 3030 persons (7.32%), from a total of 792/3030 persons (26.1 %) sIAD > 10 mmHg, and dIAD > or =10 mmHg was found in 927 out of 3030 persons (33.5%) in the right arm, and 32.4% in the left arm. In 2692 of 3030 volunteers BP, initially recorded in the dominant hand (right arm), showing sIAD> or = 10 mmHg was found in 943 (37.1%) volunteers, and when the first measurement was done in 338 left-handed volunteers it showed sIAD> or = 10 mmHg in 112 of 338 (34.1%), P < 0.001; 95% confidence interval for systolic right hand were (115.73: 116.73), and for systolic left hand 95% confidence interval were (113.17:114.15).Conclusion: significant inter-arm systolic and diastolic BP differences above (10 mm Hg) is common in the young, healthy population. Hand dominance is a significant consideration while measuring blood pressure. It is mandatory to measure blood pressure in both arms in a sitting position with a stable condition.
