Facilitators and barriers to dietary choices among older adults living in rural Edo, South-south, Nigeria

Abstract

Background Population ageing is accelerating, with the fastest growth occurring in low- and middle-income countries. Adequate nutrition is central to healthy ageing, yet little is known about the factors shaping dietary behaviours among older adults in rural African settings, where structural constraints may strongly influence dietary choice. This study explored the facilitators and barriers influencing the dietary choices among older adults aged 60 years and above living in rural communities of Edo Central, Nigeria. Methods This exploratory qualitative study was guided by the Socio-Ecological Model (SEM). Semi-structured, in-depth interviews were conducted with 22 older adults. Interview transcripts were analysed thematically using NVivo 14, with findings mapped across individual, environmental, community, and policy/system levels of the SEM. Results Fourteen subthemes were identified and organised into four overacting SEM domains. Individual drivers identified included a deep knowledge of nutrient-rich diets and a preference for natural, minimally processed foods, as well as community drivers, including cultural and traditional norms and market access, which were the facilitators. Environmental drivers, including physical and economic access, and policy/system drivers, including government policies/subsidies, food prices and inflation, were identified as the main barriers. Conclusion Dietary choices among older adults in rural Nigeria are shaped predominantly by structural and food-system constraints rather than by individual knowledge alone. Policies aimed at improving nutrition in ageing populations should prioritise strengthening rural food systems, supporting smallholder agriculture, stabilising food prices, and developing targeted social protection programmes for older adults.
