The association between intergenerational relationships and depression among older adults: A comprehensive systematic literature review

Objective: This systematic review aims to comprehensively examine the relationship between intergenerational relationships and depression among older adults in Eastern Asian countries. Methods: For this research, a systematic search was conducted on several electronic databases including PubMed, Scopus, Web of Science, ScienceDirect, and Google Scholar search engine up until June 2023. Results: Out of 953 articles initially identified, 33 met the inclusion criteria. Emotional support and financial support emerged as crucial factors that can significantly reduce depressive symptoms among older individuals. However, there are diverse and sometimes contradictory results regarding the impact of intergenerational instrumental support on depression in older adults. Conclusion: Promoting positive intergenerational relationships and enhancing support systems can greatly benefit the mental health of older adults by addressing depression within this population. This review enhances our understanding of the complex relationship between intergenerational relationships and depression among older adults. The diverse findings on intergenerational instrumental support and depression in older adults suggest the need for further research to clarify this relationship and its nuances. This research may have practical implications for policies and interventions aimed at improving the mental well-being of older adults in Eastern Asian countries.
