RESUMO
INTRODUCTION: The effect of clothing on the recording of blood pressure in a normotensive and hypertensive population remains essential remains to diagnosing and managing. METHODS: This is a cross-sectional study to measure blood pressure using a validated oscillometric sphygmomanometer in two populations. The records were made over the thicker sleeve arm and non-sleeved arm (either on bare arm or indicating the removal of the outermost garment). Clothing was categorized according to how patients attended the outpatient clinic based on the real world. RESULTS: A total of 75 patients were included with a diagnosis of hypertension whose mean age was 67.1 years (SD ± 16.3). The group of normotension included 63 patients whose mean age was 21.1 years (DS ± 2.2). There was not variability related to technique or inherent to the condition of the subject on the first and second measurements of blood pressure. In the comparative analysis, the group with normotension did not report a significant difference in systolic or diastolic blood pressure due to the effect of clothing during the first or second measurement (p> 0.05). In the group with hypertension, a significant difference was observed in the first measurement, between the group over the sleeve and non-sleeved arm (systolic blood pressure, p: 0.021, and diastolic, p: 0.001). However, when the variable order of measurement was analyzed by randomizing the initial registry with or without clothing was not found a statistical difference. CONCLUSION: Clothing does not a significant difference in the measure of blood pressure in a normotensive or hypertensive population.
