Which malnutrition screening tools are appropriate for older adults living in the community?

• A. MNA, MST, and SCREEN II
• B. BMI chart analysis
• C. 24-hour dietary recall
• D. Dietary intake frequency questionnaire alone

Answer: (A)

Screening for malnutrition in community-dwelling older adults relies on quick, validated tools tailored to aging populations. The combination of Mini Nutritional Assessment (MNA), Malnutrition Screening Tool (MST), and SCREEN II fits this need because each is specifically designed and validated for older adults and can be administered easily in home, clinic, or community settings.

MNA provides a broad snapshot that includes recent weight loss, appetite, mobility, psychological stress, and either BMI or calf circumference, giving a well-rounded view of nutritional risk in older individuals. MST is a concise two-item screen focused on unintentional weight loss and appetite decline, making it ideal for rapid triage in busy primary care or community programs. SCREEN II is specifically developed for community-dwelling seniors and covers dietary intake, weight change, disease burden, functional status, and social factors, enhancing its relevance for screening outside of hospital settings. Together, they address the multifaceted nature of malnutrition risk in older adults—from intake and weight changes to functional and health factors.

In contrast, relying on BMI alone can miss malnutrition risk in older adults, since it doesn’t capture recent weight loss, muscle loss, or functional decline. A 24-hour dietary recall or a dietary intake frequency questionnaire provides detailed intake information but is not a screening tool by itself and can be time-consuming or impractical for quick screening in the community.
