On 4 April 2025, faculty members from the Adult and Gerontological Nursing Department at Boromarajonani College of Nursing, Suphanburi, led third-year nursing students in activities organized by the Sanam Chai Subdistrict Administrative Organization to promote physical activity and improve quality of life among older adults, young people and the general public. The activities applied the PBRI Model and promoted behavioral changes through the “3 Practices, 3 Reductions” approach: exercise, diet and emotional well-being, together with reducing obesity, alcohol consumption and smoking. Participants also received guidance on using the PI Model for the Public through the LINE application. Activities included basic health screening, brain-training education to help prevent dementia, stretching demonstrations and a traditional water-pouring ceremony to seek blessings from older adults during Songkran. The event took place at Wat Sanam Chai Archaeological Site in Mueang District, Suphan Buri.
