Objective: This mini-review aimed to review the value of intergenerational programs and projects in promoting active aging, through one of its fundamental pillars: the integration and participation of older adults. Method: The methodological procedure used in this paper involved a narrative approach with analysis from different sources. Different databases were consulted (WoS, PubMed, SciELO), and organizations such as the WHO and various oficial resources were used as sources of information. Results: Intergenerational programs and projects are plans coordinated and designed by educational centers, senior centers and other organizations and associations - public and private - that want to work together for the mutual benefit of older adults, children and youth. After review the benefits of intergenerational programs and projects, it stands out one of the recent and successful iniciative implemented in Spain -the intergenerational program “Adopt a Grandparent”. This iniciative is dedicated to fostering connections between different generations with the aim of alleviating situations of loneliness among older people. Discussion and Conclusions: Participation between generations brings us closer to a more intergenerational society. The social network formed through bidirectional synergies can positively impact aging, serving as a compass for the health and psychological well-being of older people.
