Using a randomized controlled trial, the study aims to evaluate the effectiveness of a 12-week health promotion and risk prevention program, named Salutogenic Healthy Aging Program Embracement (SHAPE) for elderly-only households. Participants in the experimental group will receive 2 home visits, 10-weekly group-based activity sessions and a SHAPE health-promotion booklet. A process evaluation using face-to-face interviews will also be conducted for elderly receiving SHAPE to explore their views on the program.
