Body composition and functional assessment of nutritional status in adults: a narrative review of imaging, impedance, strength and functional techniques.
(Wiley, 2016-12-06) Smith, Sara; Madden, A. M.
The accurate and valid assessment of body composition is essential for the diagnostic evaluation of nutritional status, identifying relevant outcome measures and for determining the effectiveness of current and future nutritional interventions. Developments in technology and understanding of the influences of body composition on risk and outcome provide practitioners with new opportunities to enhance current practice and lead future improvements in practice. This is the second of a two-part narrative review which aims to critically evaluate body composition methodology in diverse adult populations, with a primary focus on its use in the assessment and monitoring of under-nutrition. Part one focused on anthropometric variables (1) and part two focuses on the use of imaging techniques, bioelectrical impedance analysis, markers of muscle strength and functional status with particular reference to developments relevant to practice.
Body composition and morphological assessment of nutritional status in adults: a review of anthropometric variables
(Wiley, 2014-11-25) Madden, A. M.; Smith, Sara
Evaluation of body composition is an important part of assessing nutritional status and provides prognostically useful data and an opportunity to monitor the effects of nutrition-related disease progression and nutritional intervention. The aim of this narrative review is to critically evaluate body composition methodology in adults, focusing on anthropometric variables. The variables considered include height, weight, body mass index and alternative indices, trunk measurements (waist and hip circumferences and sagittal abdominal diameter) and limb measurements (mid-upper arm and calf circumferences) and skinfold thickness. The importance of adhering to a defined measurement protocol, checking measurement error and the need to interpret measurements using appropriate population-specific cut-off values to identify health risks were highlighted. Selecting the optimum method for assessing body composition using anthropometry depends on the purpose (i.e. evaluating obesity or undernutrition) and requires practitioners to have a good understanding of both practical and theoretical limitations and to be able to interpret the results wisely.
