Elderly residing in elderly-only households are more vulnerable as they are socially isolated, suffer from poorer health outcomes, and are less likely to adopt health-promoting behaviors. While multi-dimensional preventive home visits provide older adults with the individualized care to cope with living in their homes, group-based education promotes peer learning and allows for social interaction. Elderly residing in elderly-only households can reap the benefits derived from the coaction of preventive home visits and group-based education, providing them with the personalized care to age healthily in their homes and a platform to develop social connectedness with their peers. This study uses the combination of preventive home visit and group-based education program to promote healthy aging in elderly living in elderly-only households.
