Effectiveness of a Mobile Phone-Based Lifestyle Program to Improve Blood Pressure Control in Adults with Hypertension in Nepal

What this Trial Is About

Researchers are evaluating a mobile health mHealth behavioral intervention called TelTex4BP for adults with hypertension in Nepal. The study aims to improve blood pressure control and reduce the risk of cardiovascular disease CVD by delivering lifestyle counseling through phone calls and text messages. This hybrid type 2 effectiveness-implementation randomized controlled trial involves patients, their families, and healthcare providers to tailor the intervention to local culture and needs. Participants in the intervention group will receive structured counseling on healthy diet, physical activity, smoking, alcohol intake, medication adherence, and follow-up reminders via monthly phone calls and 2-3 text messages per week for six months. The control group will receive usual care including antihypertensive medication prescriptions, follow-up advice, and an informational pamphlet. Follow-up assessments will occur at six and twelve months to evaluate both short-term and long-term effects. Throughout the study, participants will undergo blood pressure measurements, assessments of 10-year CVD risk, medication adherence, dietary habits, and physical activity. Researchers will also evaluate how well the intervention is adopted and maintained using the RE-AIM framework. The total participation includes the six months of intervention and six months of follow-up to monitor sustainability and effectiveness of the mHealth support.
