Body fat percentage assessment by ultrasound subcutaneous fat thickness measurements in middle-aged and older adults

Background & aims B-mode ultrasound accurately measures both muscle mass, body density and percent body fat (% BF) in younger adults, but how well it can estimate % BF in middle-aged and older adults using DXA-derived %BF as the criterion is unclear. We sought to develop % BF prediction equations for middle-aged and older adults using ultrasound subcutaneous fat thickness (SFT). Methods A cross-sectional study of Japanese adults (n = 414, 50–79...
