Table 2. Mean comparisons of height, body mass and body composition by age group.
Values are mean ± SD. For height, weight and BMI, n = 297 (20–39 y), 90 (40–59 y) and 75 (≥ 60 y), and for fat-free mass (FFM), lean mass, fat mass, BF% measures, and android/gynoid ratio, n = 297 (20–39 y), 88 (40–59 y) and 71 (≥ 60 y).
