Intergenerational interventions and the impact on health outcomes in older adults and young people: A systematic review

Background:Intergenerational interventions have gained attention due to their impact on improving health outcomes across generations, particularly in European ageing societies. This systematic review aimed to explore the effects of intergenerational interventions on older adults and young people (≤19 years) in European countries, focusing on physical, psychological, social, and QoL outcomes.Methods:This review followed PRISMA guidelines and included articles published between 2004 and 2024 from four databases: PubMed, Scopus, Web of Science, and EBSCOhost. Studies were eligible if they reported community- based intergenerational interventions involving older adults (≥65 years) and young people. Risk of bias was assessed using JBI critical appraisal tools, and a narrative synthesis was conducted to summarise findings.Results: Eight studies were included. Intergenerational interventions improved older adults’ physical performance, enjoyment, satisfaction, self-esteem, and reduced loneliness. Young participants also benefited from enhanced social-emotional skills and reduced age-related stereotypes. Intervention types included physical activities, leisure-based programs, group reminiscence, and virtual language learning.Conclusion: Intergenerational interventions show promising benefits for both age groups, particularly inpsychological and social domains. However, more rigorous research using standardised tools and randomiseddesigns is needed to strengthen the evidence base. These findings offer practical insights for public healthpractitioners promoting healthy ageing and intergenerational social connectedness.PROSPERO registration number: CRD42024538712Keywords: Adolescents, Children, European countries, Intergenerational interventions, Older Adults.
