Values are presented as means ± SD or percentage; BMD, bone mineral density.
a: Region means the site to take bone mineral densitometry assessment
LS: lumbar spine 1 to 4, FN: femoral neck, TH: total hip, Overall: category defined by the site with the lowest T-score
b: Based on the WHO classification
Normal: T-score ≧ 1.0, Osteopenia:-1.0 > T-score > -2.5, Osteoporosis: T-score ≦ -2.5
