# Tailored digital health interventions achieve clinically significant systolic BP reductions at 12 months in US populations experiencing health disparities, but the effect is conditional on design specificity for these populations rather than generic deployment

A systematic review and meta-analysis of 28 studies covering 8,257 patients found that digital health interventions produced clinically significant reductions in systolic blood pressure at both 6 and 12 months in populations experiencing health disparities (racial/ethnic minorities, low-income adults, underinsured/uninsured). The critical qualifier is that these were 'tailored initiatives designed specifically for disparity populations' rather than generic commercial deployments. The 12-month durability is notable because most digital health RCTs show effect decay. However, all 28 studies represent tailored research programs, not commercial product deployments at scale. This creates a gap between 'tailored intervention works in an RCT' and 'generic wearable deployment improves BP control at population scale.' The finding suggests digital health is not categorically excluded from reaching disparity populations, but the tailoring requirement means current commercial deployment patterns may not replicate these results. This directly addresses the 76.6% non-control gap in hypertension but only under conditions that differ substantially from real-world generic app/wearable deployment.
