The association between malnutrition, depression and cognitive decline in free-living elderly people in Cyprus: a cross-sectional study

Malnutrition, depression, and cognitive decline are interrelated conditions in the elderly population of Cyprus. Social participation and eating with others appear to have protective effects against depression, while maintaining muscle mass may help reduce the risk of cognitive decline. Public health interventions should focus on improving nutritional status and encouraging social engagement among the elderly to protect their mental health.
