  1. Data are Mean ± SD.
  2. BMC = bone mineral content
  3. BMD = bone mineral density
  4. PTH = serum parathyroid hormone
  5. 25(OH)D = serum 25-hydroxyvitamin D concentration (conversion to nmol/L is by multiplying values shown by 2.5)
  6. For entire 49 subjects enrolled: Values for cord 25(OH)D, Non-Hispanic Caucasian (n = 22), 22.3 ± 9.4 ng/mL and Hispanic (n = 27), 16.4 ± 6.5 ng/mL, p = 0.01. Values for BMC at one week, Non-Hispanic Caucasians, (n = 22), 69.5+8.8 (g) and Hispanic, (n = 27), 72.4 ± 9.2 (g), p = 0.27. Note that values in ng/mL can be converted to nmol/L by multiplying by 2.5.
