Abstract —Previous studies have reported results on 24-hour ambulatory blood pressure (ABP) in Europe and Japan, but no data exists from South America. In this study, we conducted a population survey to identify reference values compare with clinic, home, self-measured values. A random sample of 2650 adults was selected among 190 000 people covered by our prepaid healthcare institution. Clinic (physician nurse) home (nurse) measurements were performed 3 times each, semiautomatic electronic equipment. Self-measurements the subjects manually activating device. We analyzed 1573 individuals who not receiving antihypertensive therapy 1921 participants. Self-measurement available subgroup 577 participants younger than whole sample. Normal limits estimated as those that best correlated 140/90 mm Hg at clinic. Estimated 125/80 for (range: 122 128 77 83 Hg) 129/84 daytime 127 132 81 86) pressure, depending gender age. Ambulatory clinic pressures increased The age-dependent increase ABP similar women men. Average 124/79 physician 123/78 nurse. Nurse measurement 125/78 Hg, 121/77 118/74 Hg. self-measurement 119/77 Hg; nurse 118/77 121/78 115/72 115/73 This study shows average value are suitable upper normality. Higher would yield an artificially higher prevalence white coat hypertension. Most showed levels when personnel or home.
