Adherence
The same mHealth intervention does NOT produce statistically significant reductions in systolic or diastolic blood pressure four years after completion, nor does it significantly reduce the incidence of hypertension, although a non-significant trend toward reduced hypertension risk was observed in high-adherence subgroups.
Do not expect this mobile health program to significantly lower your blood pressure, even if it helps you lose weight. The study showed no significant change in systolic or diastolic blood pressure four years after the intervention. However, the weight loss achieved is still a valuable health outcome, and you should continue to monitor your blood pressure with your healthcare provider.
The intervention did not result in changes in systolic (–2.54 mm Hg, 95% CI –8.23 to 3.15) or diastolic (3.41 mm Hg, 95% CI –0.75 to 7.57) blood pressure compared with the control group. The intervention reduced the risk of developing hypertension, but the result was not significant (risk ratio (RR) 0.76, 95% CI 0.45-1.28).
