Rationale: Visual assessment of temporal muscle wasting plays an important role in assessing malnutrition in clinical practice. The aim is to examine the reliability and validity of the visual assessment of temporal wasting as an assessment method of muscle wasting in the older adults.

Methods: A cross-sectional study was conducted between September 2015 to May 2016. 73 subjects aged 65 or older were recruited from two facilities and one community walking group. Temporal wasting was visually evaluated by two examiners. Temporal muscle thickness was measured using ultrasonography. Nutritional status was evaluated by anthropometric measurements including body mass index, arm muscle circumference and calf circumferences. Inter-rater agreement of visual assessment of temporal wasting was tested by Kappa coefficient. Discriminative validity and known-group validity were assessed to show the validity of the temporal wasting as an indicator of muscle depletion in malnutrition.

Results: Inter-rater agreement of visual evaluation of temporal wasting was shown as Kappa coefficient of 0.594. Subjects with severe or mild temporal wasting had significantly lower levels of arm muscle circumference and calf circumferences when compared to subjects with no temporal wasting, although there was no significant difference in parameters of muscle mass between mild and severe temporal wasting. The temporal muscle thickness was significantly decreased in subjects with severe temporal wasting compared to subjects with mild or no temporal wasting, although there was no significant difference between subjects with mild or no temporal wasting.

Conclusion: Temporal wasting can be evaluated visually with a moderate agreement and valid for nutritional screening but not sufficient to evaluate detailed degree of muscle wasting.
