Table 2 State of bone density

From: The relationship between bone density and the oral function in older adults: a cross-sectional observational study

All (754)   Osteoporosis (n = 260) Decreased bone mass (n = 287) Normal (n = 207) P-value
  SOS (m/s) 1469 (1460, 1475.3) 1490 (1485, 1496) 1516 (1509, 1526) < 0.001
  YAM (%) 65 (61, 68) 75 (73, 77) 88 (84, 94) < 0.001
Male (276)   Osteoporosis (n = 65) Decreased bone mass (n = 95) Normal (n = 116) P-value
  SOS (m/s) 1473 (1465.5, 1478) 1492 (1487, 1495.8) 1518 (1509, 1529.5) < 0.001
  YAM (%) 66 (62, 68) 75 (73, 77) 89 (84, 95.8) < 0.001
Female (478)   Osteoporosis (n = 195) Decreased bone mass (n = 192) Normal (n = 91) P-value
  SOS (m/s) 1468 (1460, 1474) 1489 (1484.5, 1496) 1513 (1509.3, 1522) < 0.001
  YAM (%) 65 (61, 68) 75 (72.3, 77) 87 (85, 91) < 0.001
  1. Median (first quartile, third quartile) or the number of people (%)
  2. Based on the diagnostic criteria for osteoporosis, we classified cases with a YAM value of ≤80 as decreased bone mass, ≤70 as osteoporosis, and all others as normal
  3. P-value: Kruskal-Wallis test
