This study assessed the effectiveness of a community program led by trained volunteers over eight weeks, with participants randomly assigned to intervention or wait-list control groups. Results showed that intervention group participants progressed significantly from the cognitive to the behavioral stage in motivational readiness for physical activity (P = .001), healthy eating (P = .001), stress management (P = .001), and adopting a healthy lifestyle (P = .003) compared to controls. Additionally, young participants reported increased self-management abilities (F(1.134) = 4.957, P = .028) and improved knowledge about hypertension (F(1.160) = 16.571, P < 0.0005, ?2 = .094). Traditional medical practice often overlooks psychosocial determinants of health behavior, suggesting a need for community-based, peer-led programs to complement clinical care and promote holistic population health beyond clinical settings.
