Nutritional Risk, Depression, and Physical Function in Older People Living Alone

Area of Science:

• Gerontology
• Public Health
• Nutrition Science

Background:

• Nutritional risk is a significant concern for older adults, particularly those living alone.
• Factors like depression and impaired physical function can exacerbate nutritional challenges in this demographic.

Purpose of the Study:

• To investigate the association between depression, physical function, and nutritional risk in older adults living alone.
• To identify specific factors contributing to nutritional risk in this population.

Main Methods:

• A cross-sectional study involving 2896 adults aged 65+ living alone in South Korea.
• Data collected via surveys and analyzed using descriptive statistics, chi-squared tests, t-tests, weighted multiple regression, and binary logistic regression.

Main Results:

• 44.8% of participants were identified as being at nutritional risk.
• Depression, chewing limitations, instrumental activities of daily living (IADL) dependency, and basic physical movement limitations were significant predictors of nutritional risk.
• Individuals with IADL dependency were 2.59 times more likely to be at nutritional risk.

Conclusions:

• Depression and physical function deficits are strongly linked to nutritional risk in older adults living alone.
• Routine nutritional screening, including assessment of mental health and physical capabilities, is crucial for this vulnerable group.
• Interventions addressing depression and physical function may help mitigate nutritional risks in elderly individuals living independently.
