Key result
A combined pedometer and home blood pressure monitoring program significantly reduced systolic blood pressure by 8.1 mm Hg (95% CI -12.3 to -3.9; p<0.01) compared to control at 12 months.
Why the study?
Hypertension and diabetes frequently coexist, making BP control difficult in community-dwelling elderly adults who lack effective prevention and control strategies.
Do self-monitoring devices (pedometer and home blood pressure monitoring) reduce blood pressure in community-dwelling older adults with hypertension and diabetes?
RCT (n=180)
2x2 factorial

Supports combined pedometer and home BP monitoring in older adults with hypertension and diabetes; extends self-monitoring evidence to this comorbid population.
BACKGROUND: Hypertension and diabetes frequently coexist, which results in the difficulty of hypertension control in community-dwelling elderly adults who lack effective prevention and control strategies. The aim of this study is to determine whether a combined pedometer and home blood pressure monitoring (HBPM) programme could improve blood pressure (BP) among community-dwelling elderly adults with hypertension and diabetes. METHODS: The trial was a 2×2 factorial randomised clinical trial that recruited 180 community-dwelling elderly people (aged ≥60) with hypertension and diabetes in Tianjin, China. Participants were randomly assigned to control, pedometer, HBPM, and pedometer+HBPM groups. Intervention period was 12 months. The coprimary outcomes of the study were systolic and diastolic BP; the secondary outcomes included the proportion of patients with controlled hypertension. BP was measured twice in the right arm using a mercurial sphygmomanometer. The mean of these two measurements was taken as the BP value. RESULTS: At 12 months, compared with the control group, the adjusted differences in least squares mean (95% CI) in systolic and diastolic BP changes for pedometer, HBPM, and pedometer+HBPM groups were -4.2 (-8.4 to 0.1), -2.7 (-6.9 to 1.5) and -8.1 (-12.3 to -3.9) mm Hg (p<0.01); -3.2 (-5.2 to -1.1), -0.1(-2.1 to 1.9) and -3.6 (-5.6 to -1.5) mm Hg (p<0.001), respectively; the adjusted difference in percentage (95% CI) in the controlled hypertension (BP <140/90 mm Hg) for pedometer, HBPM and pedometer+HBPM groups were 7.5 (-12.2 to 27.1), 9.9 (-10.4 to 30.3) and 23.1 (5.0 to 41.1) (p=0.09). CONCLUSION: Combination pedometer and HBPM interventions can significantly decrease BP levels in elderly adults with hypertension and diabetes. TRIALS REGISTRATION NUMBER: UMIN000021613.

Gu et al. (2019) conducted an RCT in Hypertension and diabetes (n=180). Pedometer and home blood pressure monitoring (HBPM) vs. Control was evaluated on Change in systolic and diastolic blood pressure (Adjusted difference in systolic BP (pedometer+HBPM vs control) -8.1 mm Hg, 95% CI -12.3 to -3.9, p=<0.01). A combined pedometer and home blood pressure monitoring program significantly reduced systolic blood pressure by 8.1 mm Hg (95% CI -12.3 to -3.9; p<0.01) compared to control at 12 months.
