Assessing Nutrition in Older Adults

Assessing Nutrition in Older Adults

WHY: While poor nutrition is not a natural concomitant of aging, older adults are at risk for malnutrition due to physiological, psychological,
social, dietary, and environmental risk factors. Weight loss in older adults loss is often associated with a loss of muscle mass and can ultimately
impact functional status. Malnutrition in older adults is associated with complications and premature death. The progression to malnutrition is
often insidious and often undetected. The nurse plays a key role in prevention and early intervention of nutritional problems.
BEST TOOL: The Mini-Nutritional Assessment Short-Form (MNA®-SF) is a screening tool used to identify older adults (> 65 years) who are
malnourished or at risk of malnutrition. The MNA®-SF is based on the full MNA®, the original 18-item questionnaire published in 1994 by
Guigoz, et al. The most recent version of the MNA®-SF was developed in 2009 (Kaiser et al., 2009) and consists of 6 questions on food intake,
weight loss, mobility, psychological stress or acute disease, presence of dementia or depression, and body mass index (BMI). When height
and/or weight cannot be assessed, then an alternate scoring for BMI includes the measurement of calf circumference. Scores of 12-14 are
considered normal nutritional status; 8-11 indicate at risk of malnutrition; 0-7 indicate malnutrition. An advantage of the tool is that no
laboratory data are needed. An in-depth assessment and physical exam should be performed when patients are identified to be malnourished
or at nutritional risk. A review of symptoms and objective clinical findings should be assessed in addition to the patient’s cultural factors,
preferences, social needs/desires surrounding meals. A 72-hour food dairy recording the patent’s consumption is another important
supplement to the MNA®-SF.
TARGET POPUTLATION: The MNA®-SF provides a simple, quick method of identifying older adults who are at risk of malnutrition. The
MNA®-SF should be completed quarterly for institutionalized older adults and yearly for normally nourished community-dwelling older adults.
VALIDITY AND RELIABILITY: The full MNA® has been validated in many research studies with older adults in hospital, nursing home,
ambulatory care, and community settings. Studies have demonstrated internal consistency and inter-observer reliability to range from 0.51
to 0.89 (Guigoz, 2006). The MNA®-SF has a sensitivity of 89%, specificity of 82%, and a strong positive predictive value (Youden Index = 0.70)
(Kaiser et al., 2009). While the MNA®-SF was developed from the full MNA®, reliability of the MNA®-SF is not yet available (Skates & Anthony,
2012).
STRENGTHS AND LIMITATIONS: Unlike many other nutritional instruments, the full MNA® and the MNA®-SF were developed to be userfriendly,
quick, non-invasive, and inexpensive. The MNA®-SF takes about 5 minutes to complete and the questions can easily be incorporated
into a complete geriatric assessment. The MNA® and MNA®-SF have been used extensively in clinical research in over 200 international studies
(Cereda, 2012). A limiting factor may be accurate assessment of height and weight to obtain BMI in bedridden individuals. To that end, users
of the MNA®-SF can substitute calf circumference for BMI. However, clinician lack of familiarity with the requirement of measuring calf
circumference is a potential limitation (DiMaria-Ghalili & Guenter, 2008). Question A focuses on food intake (not artificial nutrition), and
the appropriateness of the MNA®-SF for use in older adults who receive tube-feeding (Bauer, et al., 2008) or total parenteral nutrition needs
to be considered. Patients receiving tube-feeding or total parenteral nutrition should be monitored by a dietitian or trained nutrition support
professional.
