Abstract
Total hemoglobin concentration [total-Hb] and reduced scattering coefficient (µs’) measured using near-infrared time-resolved spectroscopy in supraclavicular regions (parameters used to evaluate brown adipose tissue density (BAT-d)) were compared between children and adults. This study included 217 children (114 girls and 103 boys; 2.1 ± 1.6 (mean ± SD) years) and 139 adults (103 females and 36 males; 37.1 ± 5.8 years). Parameters for BAT-d values in the supraclavicular region were significantly higher in children ([total-Hb], 86.9 ± 21.5 µM: µs’, 11.2 ± 1.6 cm-1) than in adults ([total-Hb], 62.7 ± 21.7 µM: µs’, 7.5 ± 1.2 cm-1).
