Risk Factors for Malnutrition among Older Adults in the Emergency Department: A Multicenter Study

Area of Science:

• Gerontology
• Public Health
• Nutritional Science

Background:

• Malnutrition is prevalent in older adults, frequently overlooked by healthcare providers.
• It significantly impacts recovery from illness and injury in the elderly population.

Purpose of the Study:

• To identify modifiable risk factors contributing to malnutrition in older patients.
• Investigate the association between various lifestyle and health factors and nutritional status.

Main Methods:

• A prospective, cross-sectional, multicenter study involving 252 non-critically ill adults aged 65 years and older.
• Utilized random time block sampling and assessed malnutrition via the Mini Nutritional Assessment Short-Form.
• Examined risk factors including food insecurity, oral health, depressive symptoms, mobility, transportation, loneliness, and medication side effects.

Main Results:

• The prevalence of malnutrition in the study sample was 12%.
• Significant risk factors identified included poor oral health (54% population attributable risk proportion), food insecurity (14%), and transportation issues affecting diet (12%).
• Patient characteristics associated with malnutrition included lower educational attainment, hospital admission, and assisted living facility residence.

Conclusions:

• This study highlights several modifiable factors linked to malnutrition in older adults.
• Addressing poor oral health, food insecurity, and transportation barriers may mitigate malnutrition prevalence.
