Mobile health apps reduced mean systolic blood pressure by 5 mmHg (from 140 to 135 mmHg) over 12 months in hypertensive adults in Tanzania with p < 0.05.
RCT (n=300)
Participants were randomized into two groups
Does a mobile health app reduce systolic blood pressure in hypertensive adults?
The use of mobile health apps significantly improves systolic blood pressure control among hypertensive adults in resource-limited settings.
Effect estimate: Mean reduction of 5 mmHg (95% CI -6 to -2 mmHg)
Absolute Event Rate: 135% vs 140%
p-value: p=<0.05
Hypertension is a significant public health issue in Tanzania, where effective management strategies are limited by access to healthcare resources and adherence to prescribed medication regimens. A longitudinal study design was employed with a sample size of 300 hypertensive adults recruited from urban and rural areas. Participants were randomized into two groups: one using a mobile health app for hypertension management (Intervention Group) and the other receiving standard care without apps (Control Group). Blood pressure readings were recorded at baseline, 6 months, and 12 months post-intervention. The Intervention Group showed a statistically significant reduction in mean systolic blood pressure from 140 mmHg to 135 mmHg over the 12-month period (p < 0. 05), with a confidence interval of -6 to -2 mmHg. Mobile health apps can be effective tools for improving blood pressure control in hypertensive adults, particularly those living in resource-limited settings such as Tanzania. Further research should explore the long-term sustainability and scalability of mobile health app interventions in diverse populations across different geographical regions. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
Mwagale et al. (Sun,) conducted a rct in Adults with hypertension in urban and rural areas of Tanzania (n=300). Mobile health app for hypertension management vs. Standard care without apps was evaluated on Change in mean systolic blood pressure over 12 months (Mean reduction of 5 mmHg, 95% CI -6 to -2 mmHg, p=<0.05). Mobile health apps reduced mean systolic blood pressure by 5 mmHg (from 140 to 135 mmHg) over 12 months in hypertensive adults in Tanzania with p < 0.05.
