Abstract
Our understanding of how eating behaviours change in later life have been dominated by the studies of physiological and biological influences on malnutrition. Insights from these studies were consequently used to develop interventions, which are predominantly aimed at rectifying nutritional deficiencies, as opposed to interventions that may enable older adults to eat well and enjoy their food-related life well into older age. The objective of the present review is to summarise the existing knowledge base on psychosocial influences on eating behaviours in later life. Following comprehensive searches, review, and appraisal, 53 articles were included (22 qualitative and 31 quantitative) to provide a greater understanding of the mechanisms underpinning the psychosocial factors influencing eating behaviours. Our analysis identified eight underpinning psychosocial factors that influences eating behaviours in later life; (1) health awareness & attitudes, (2) food decision making, (3) perceived dietary control, (4) mental health & mood, (5) food emotions & enjoyment, (6) eating arrangements, (7) social facilitation, and (8) social support. The importance and lasting influence of early food experiences were also identified as contributing to eating behaviours in later life. The review concludes with the call for further investigation into specific psychosocial factors that influence eating behaviour, calls for improvements in methodologies, and a summary of psychosocial barriers and enablers to eating well in later life.
