Muscle loss and loss of lean body mass are common features of aging. This loss may progress to the point of sarcopenia, which is difficult to reverse. Consequently, it is necessary to measure lean body mass loss reliably and easily in the aging population. Gold standard methods (e.g., dual‐energy x‐ray absorptiometry, DXA) are difficult and time consuming. The purpose of this investigation was to determine whether hand‐held ultrasound (HU) could reliably correlate with DXA measures in healthy elderly. Seventy‐nine healthy elders (65+) were evaluated over a 24‐week period. Lean leg mass (LLM) was measured by DXA, and muscle thickness at thigh, calf and hamstring loci was measured via a HU device (BodyMetrix‐2000) at baseline, 12‐week and 24‐week time points. LLM and thigh muscle thickness were weakly but significantly correlated at all time points (baseline: r = 0.30, p = 0.003; 12‐week: r = 0.31, p = 0.004; 24‐week: r = 0.23, p = 0.043). LLM was also correlated with hamstring thickness ( r = 0.23, p = 0.038) and calf thickness ( r = 0.24, p = 0.031) at the 12‐week time point. No correlation was found between the change of LLM and any muscle thickness over time.These data demonstrated poor reliability of the HU device for assessing and tracking muscle mass over time in older adults.
