A Low-Cost Educational Intervention for Rural Hypertension Control: Lessons for National Scale-Up.

Hypertension poses a major public health challenge in rural India, exacerbated by limited awareness and healthcare access. This quasi-experimental study among 110 hypertensive patients at a rural health center in Delhi assessed the impact of a low-cost, multifaceted educational intervention comprising flipchart-based counselling, voice calls, and Short Message Service (SMS) reminders. The intervention significantly improved blood pressure control (from 14.7% to 52.9%), medication adherence, physical activity, and dietary practices. Improvements were statistically significant, and participants with normal or reduced body mass index (BMI) showed better outcomes. The approach was simple and scalable and aligned with the National Programme for Prevention and Control of Non-Communicable Diseases goals. Persistent gaps in routine screenings and lifestyle adherence suggest a need for qualitative research and enhanced follow-up mechanisms.
