Abstract

BACKGROUND: The association between sodium intake and successful aging is not elucidated to date. OBJECTIVE: To evaluate the association between sodium intake and successful aging, in people aged >50 years, living in Greece. METHODS: A cross-sectional study was conducted in middle aged and older adult participants of the ATTICA (n = 1,128) and MEDIS (n = 2,221) epidemiological studies. Anthropometric, clinical, socio-demographic and lifestyle characteristics derived through standard procedures and questionnaires. Sodium intake was measured based on the USDA Food Composition database; table salt or salt from processed foods were not evaluated. Successful aging was assessed using the Successful Aging Index (SAI, range 0– 10, higher values indicating higher successful aging) comprising of health-related, social, lifestyle and clinical characteristics. RESULTS: Participants with ≥1500 mg/day sodium intake had 20.2% on average lower SAI score compared to those with 70-males/>70-females, – 90% vs. 82.5%, p <0.001) and overweight/obese participants (high vs. low: overweight/obese/normal weight, – 59% vs. – 35%, p’s <0.05). CONCLUSIONS: Daily sodium intake of
