ABSTRACT
INTRODUCTION: Promoting healthy aging is a public health goal, especially in regions with a high proportion of older adults, such as Greece. This cross-sectional study investigated the association of fish n-3 PUFA intake with indicators of healthy aging among older Greek Peloponnesian adults.
METHODS: In total, 449 individuals > 60 years of age were enroled. Sociodemographic, anthropometrical, medical, mobility, balance, lifestyle, dietary, cognitive and mental characteristics were assessed through validated questionnaires and procedures.
RESULTS: Analyses revealed that n-3 PUFA intake was associated with fewer depression symptoms (p < 0.001), higher cognition levels (p = 0.012) and levels of healthy aging (p < 0.001), derived from Successful Aging Index (SAI). In parallel, n-3 PUFA intake was associated with higher adherence to the Mediterranean diet (p < 0.001). Additionally, n-3 PUFA intake was inversely correlated with the presence of long COVID-19 symptomatology (p = 0.036). No association of n-3 PUFA intake with mobility or physical performance and balance (all ps> 0.05) was detected.
CONCLUSION: The results underscore the significance of nutrition in older adults, highlighting the possible protective impact of n-3 PUFAs on maintaining functionality. Future prospective studies may validate these associations and contribute to the development of targeted nutritional strategies for older adults.
