The aim of this study was to evaluate the long-term reproducibility and validity of 24-h ambulatory blood pressure measurements (ABPM) in an unselected elderly population. In a rural Finnish community 503 randomly chosen invited persons over 65 years of age participated and went through 24-h ABPM. As part of the validation of the methodology, the reproducibility study was conducted in 26 persons (age 65-76 years). Two identical sets of measurement were performed at 4-12 (median 8) month intervals. The agreement between measurements was assessed by correlation coefficients and standard deviation (SD) of the differences. There were no significant differences in 24-h, daytime and night-time average diastolic blood pressure (DBP) and daytime average systolic blood pressure (SBP) between the two measurements. During the second measurement, 24-h SBP and night-time average SBP were slightly higher than those obtained by the first monitoring. Average 24-h SBP and DBP were 18 and 7 mmHg lower, respectively, than office blood pressure averages. The correlation coefficients were significantly higher for 24-h ambulatory blood pressure than for office blood pressure. The SD of the mean difference between visits was significantly lower for 24-h ambulatory blood pressure than for office blood pressure measurements. These findings show that the long-term reproducibility of ambulatory blood pressure is good in an elderly unselected population and better than the office blood pressure reproducibility. |
