The effect of mobile health focused on diet and lifestyle on blood pressure: a systematic review and Meta-analysis.

AIM
To determine the effect of mobile health (mHealth) focused on diet and lifestyle on blood pressure (BP).


METHODS
We performed a systematic review with meta-analysis using the mean difference (MD) of change from baseline as an effect measure. MEDLINE via PubMed, Cochrane Central, and EMBASE were reviewed until May 6, 2020. We included randomized controlled trials of adults who participated in mHealth focused on diet and lifestyle. Interventions were grouped according to the presence of health professional intervention (PI) (PI+mHealth or mHealth only). Eligible controls did not participate in mHealth and were classified as active comparator (PI) or no intervention (NI). Subgroup analyses were performed according to the presence of prior cardiovascular disease and hypertension status.


RESULTS
We included 44 trials involving 24,692 participants. Mobile health interventions were superior to NI in reducing SBP in both situations: alone (MD = -1.8 mmHg; 95%CI: -3.6; 0.0) or with PI (MD = -5.3 mmHg; 95%CI: -7.5;-3.1), with a greater effect size in the latter group (p = 0.016). This benefit was not observed when the control was PI. DBP and SBP had consistent results. There was a marked effect of PI+mHealth vs. NI on the BP reduction among hypertensive participants.


CONCLUSIONS
Current evidence shows that mHealth focused on diet and lifestyle can reduce BP, especially when implemented in hypertensive participants, and PI may provide additional benefit.
