Physiological aging can lead to an increase in blood pressure (BP) over time even in regularly exercising elders. Office BP measurements (OBPM) might be unable to detect these BP variations. The aim of this study was to analyze BP changes over 3.5 years in active elders using ABPM. The study involved 80 active subjects ≥65 years old who exercised regularly. At baseline and again 3.5 years later, all subjects had lab tests, weight, body mass index (BMI), body composition, resting energy expenditure (REE) recorded; they underwent OBPM, ABPM and physical activity assessment. Over 3.5 years, our sample's mean weight, BMI, body composition, REE, albumin, and physical activity levels, did not change significantly. The prevalence of hypertension detected by OBPM dropped from 68.8% to 61.3%. ABPM revealed an increase in mean 24-h BP (δsystolic: 5.3 ± 13.6 mmHg; p = 0.001; δdiastolic: 1.8 ± 6.7 mmHg; p = 0.018) and mean daytime BP (δsystolic: 5.8 ± 13.5 mmHg; p = 0.001; δdiastolic: 1.9 ± 7.1 mmHg; p = 0.022); the prevalence of hypertension detected by ABPM increased from 50% to 65%, also due to an increase (from 8.8% to 16.3%) in masked hypertension. There was no correlation between BP changes and changes in body composition and REE. BP tends to increase over time in active elders, regardless of changes in body composition or level of physical activity. ABPM is an appropriate method for detecting these BP variations in active elders and to reveal cases of masked hypertension that might otherwise escape detection by OBPM

Abstract

Physiological aging can lead to an increase in blood pressure (BP) over time even in regularly exercising elders. Office BP measurements (OBPM) might be unable to detect these BP variations. The aim of this study was to analyze BP changes over 3.5 years in active elders using ABPM. The study involved 80 active subjects ≥65 years old who exercised regularly. At baseline and again 3.5 years later, all subjects had lab tests, weight, body mass index (BMI), body composition, resting energy expenditure (REE) recorded; they underwent OBPM, ABPM and physical activity assessment. Over 3.5 years, our sample's mean weight, BMI, body composition, REE, albumin, and physical activity levels, did not change significantly. The prevalence of hypertension detected by OBPM dropped from 68.8% to 61.3%. ABPM revealed an increase in mean 24-h BP (δsystolic: 5.3 ± 13.6 mmHg; p = 0.001; δdiastolic: 1.8 ± 6.7 mmHg; p = 0.018) and mean daytime BP (δsystolic: 5.8 ± 13.5 mmHg; p = 0.001; δdiastolic: 1.9 ± 7.1 mmHg; p = 0.022); the prevalence of hypertension detected by ABPM increased from 50% to 65%, also due to an increase (from 8.8% to 16.3%) in masked hypertension. There was no correlation between BP changes and changes in body composition and REE. BP tends to increase over time in active elders, regardless of changes in body composition or level of physical activity. ABPM is an appropriate method for detecting these BP variations in active elders and to reveal cases of masked hypertension that might otherwise escape detection by OBPM
