Cross-sectional study of the association between nutrition and depression in older people living in nursing homes

The results show a strong association between depression and malnutrition in older people. Malnutrition is a common occurrence among older people, and age is a significant risk factor. Similarly, depression is more common among older people living in nursing homes, and increasing age also raises depression levels. Therefore, future research should focus on conducting randomized, double-blind, placebo-controlled trials to confirm the effectiveness of nutritional interventions and oral nutritional supplements in treating depression and improving cognitive function.
