IntroductionAfrica is experiencing a gradual demographic shift due to rising life expectancy and increasing urbanisation. In sub-Saharan Africa, elderly individuals typically reside with their children. The rise in life expectancy by almost a decade and the prevalence of precarious living conditions raise concerns about the sustainability of the healthcare system, which has traditionally relied on intergenerational solidarity.MethodsThe research aims to analyse the evolving role of older adults in Cameroonian society and to examine the potential impact of this change on intergenerational relationships and the health of older adults. A qualitative methodology was employed, using intergenerational focus groups in Cameroon.ResultsTraditionally, older adults held a central role in knowledge transmission through discourse. However, the modernisation of society is challenging this position.The emergence of new technologies, particularly communication tools, is leading to a questioning of older adults’ experiential knowledge. Societal changes are contributing to a decline in respect for older adults in discourse. Older adults deplore these societal changes and fear for their place in society while young people are questioning the central role of older people in society.DiscussionThese changes could reduce the sense of usefulness of older people, with negative consequences for their health. Several studies have highlighted the impacts of ageism on the health of older adults in industrialised countries. However, there are little data on the impact of the marginalisation of older adults on their health in industrialising societies. Further research is needed to study the impact on the health of older adults.
