Cross-National Survey About Nutrition and Nutrition Communication Among Older Adults Aged 60 Years and Above

<b>Background/Objectives:</b> The global population is undergoing a significant demographic shift characterised by an increasing proportion of older individuals. Healthy aging has become a priority for personal well-being and sustainable healthcare systems, with nutrition playing a pivotal role. However, the rise in non-communicable diseases (NCDs), malnutrition, and a shift in eating behaviour underscore the need for tailored, effective nutrition communication strategies. This research is intended to provide the basic data needed to support the development of tailored nutritional communication strategies and practices. <b>Methods:</b> To investigate these aspects, a cross-national survey about nutrition and nutrition communication was conducted within the framework of the Innovative Training Network SmartAge, focusing on older adults aged 60 years and above in Germany, Switzerland, Spain, and France (each 25%; N = 1000 persons). This paper specifically focuses on the development, methodology, and discussion of the survey and aims to investigate the characteristics of the sample in relation to their dietary patterns and food choices within the European context. <b>Results:</b> The analysis identified significant associations between various plant- and animal-based food items and the variables gender, age group, and country. Spanish participants showed a dietary pattern towards the Mediterranean Diet, while German participants showed tendencies towards the Western Diet. Furthermore, the findings revealed that protein-rich foods such as meat, fish, nuts and seeds, legumes, and (whole) grains were infrequently consumed, particularly among German and Swiss participants. <b>Conclusions:</b> This study highlights the need to promote adequate protein intake among older adults, emphasising diverse sources like legumes, nuts and seeds, (whole) grains, and lean meats to support healthy aging. For the development of future nutrition communication strategies, the influence of the specific social, cultural, and traditional factors needs to be considered.
