Objective
To identify
malnutrition assessment methods in cancer patients and assess their
content validity based on internationally accepted definitions for
malnutrition.
Study Design and Setting
Systematic
review of studies in cancer patients that operationalized malnutrition
as a variable, published since 1998. Eleven key concepts, within the
three domains reflected by the malnutrition definitions acknowledged by
European Society for Clinical Nutrition and Metabolism (ESPEN) and the
American Society for Parenteral and Enteral Nutrition (ASPEN): A:
nutrient balance; B: changes in body shape, body area and body
composition; and C: function, were used to classify content validity of
methods to assess malnutrition......
Results
Thirty-seven assessment methods were identified in the 160 included articles. Mini Nutritional Assessment (M-CVIA–C = 0.72), Scored Patient-Generated Subjective Global Assessment (M-CVIA–C = 0.61), and Subjective Global Assessment (M-CVIA–C = 0.53) scored highest M-CVIA–C.
Conclusion
A
large number of malnutrition assessment methods are used in cancer
research. Content validity of these methods varies widely. None of these
assessment methods has acceptable content validity, when compared
against a construct based on ESPEN and ASPEN definitions of
malnutrition.
