Interactive mobile health interventions significantly reduced systolic blood pressure by 3.85 mm Hg (95% CI, -4.74 to -2.96) and diastolic blood pressure by 2.19 mm Hg compared to control.
Meta-Analysis (n=4,271)
Does interactive mobile health intervention reduce blood pressure in adults?
Interactive mobile health interventions significantly improve both systolic and diastolic blood pressure control in adults, with the greatest benefit seen in those with inadequate baseline control.
Effect estimate: Mean difference -3.85 mm Hg (SBP) (95% CI -4.74 to -2.96)
Despite the availability of effective drugs, blood pressure (BP) control remains poor among most populations. To explore the effects of interactive mobile health (mhealth) intervention on BP management and find out the optimal target population, we performed a systematic review and meta-analysis of randomized controlled trials to estimate the pooled effects of mhealth intervention on BP control. PubMed, EMBASE, Cochrane Library, and CNKI were searched to identify eligible randomized controlled trials published between January 15, 2007 and April 28, 2019, and bibliographies of eligible articles were further reviewed. Random-effect models were utilized to pool estimates of net changes in systolic BP and diastolic BP between mhealth intervention group and control group. Eleven randomized controlled trials met the inclusion criteria, with a total sample size of 4271 participants. Compared with the control group, mhealth intervention was associated with significant changes in systolic BP and diastolic BP of -3.85 mm Hg; 95% CI, -4.74 to -2.96 and -2.19 mm Hg; 95% CI, -3.16 to -1.23, respectively. Subgroup analyses revealed consistent effects across study duration and intervention intensity subgroups. In addition, participants with inadequate BP control at recruitment might gain more benefits with mhealth intervention. Therefore, interactive mhealth intervention may be a useful tool for improving BP control among adults, especially among those with inadequate BP control.
Lu et al. (Mon,) conducted a meta-analysis in Inadequate blood pressure control (n=4,271). Interactive mobile health (mhealth) intervention vs. Control group was evaluated on Net changes in systolic BP and diastolic BP (Mean difference -3.85 mm Hg (SBP), 95% CI -4.74 to -2.96). Interactive mobile health interventions significantly reduced systolic blood pressure by 3.85 mm Hg (95% CI, -4.74 to -2.96) and diastolic blood pressure by 2.19 mm Hg compared to control.
