Abstract： Objective To investigate bone health conditions in 1637 aged women. Methods From May 2004 to October 2008, Bone mineral density (BMD) of 1637 women at age of more than 60 years old were measured by Hologic DephiA dual energy X-ray absorptiometry (DXEA) in Huadong hospital affiliated to Fudan University. All data were compared and analyzed among each group which will be divided by every ten years. Those women were divided into groups on 10 years range. BMD of lumbar vertebral and hip bone,fracture incidence and bone turnover marker were compared and analyzed. Results (1) BMD: at age of 3=90, 80 - 89, 70 - 79, 60 - 69, BMD of the lumbar vertebral 2 - 4(L2-4) values were (0. 96 ± 0. 18),(0. 90 ± 0. 20) , (0. 81 ± 0. 16) , (0. 83 ± 0. 14) g/cm2 , respectively. There were significantly increased BMD of lumbar of women at the age of 80 - 89 and ≥90 year-old compared with those of 60 - 69 year-old (P<0. 05). At age of ≥90,80 -89,70-79,60 -69 BMD of femur neck, Total, Torch, Ward's trianger were(0. 60 ±0. 11) , (0. 65 ±0. 11) ,(0. 47 ±0. 09) ,(0. 37 ±0. 09) g/cm2; at age of 80 -89 BMD of FN,Total, Torch, Ward's trianger were(0. 57 ±0. 10) , (0. 68 ±0. 13) , (0. 48 ±0. 11) , (0. 35 ±0. 10) g/cm2;at age of 70-79 BMD of FN, Total, Torch, Ward's trianger were (0.57±0. 10) ,(0. 69 ±0. 12), (0.49± 0. 10) , (0. 36 ± 0. 11) g/cm2; at age of 60 - 69 BMD of FN, Total, Torch, Ward's trianger were (0. 63 ± 0. 10) , (0. 76 ±0. 12) , (0. 54 ±0. 10), (0. 45 ±0. 15) g/cm2; There were significantly decreased in BMD of hip at the age of 70 - 79, 80 - 89,≥90 year-old compared with those of 60 - 69 year-old (P < 0. 05).(2) Fracture incidence: one time fracture incidence at age of 60 - 69,70 - 79,80 - 89, ≥ 90 were 34. 8 % (242/695) ,45. 0% (296/658) ,51. 3% (137/267) ,5/17. There were increasing trend of fracture in aged women. (3) Bone turnover marker of bone Gla protein (BGP) N-mid(N-midBGP) in serum and C-terminal telopeptide of type Ⅰ collagen/Cr (CTX/Cr) in urine values were (17 ±5) μg/L, (106 ±56) μg/mmol at age of more than 90 years ,(17 ±7) (μg/L,(128 ±99)μg/mmol at age of 80-89 years,(21 ± 14) μg/L,(182 ± 173)μg/mmol at age of 70-79 years, (25±13)μg/L, (190 ± 168)μg/mmol at age of 60 - 69 years. There were significant decreased trends of N-midBGP at age of 70 -79,80 -89 compared with that of 60-year (P < 0. 05). There were significant decreased trends of CTX/Cr 80 - 89 compared with that of 60-year (P < 0. 05). Conclusions There were significant decreased bone metabolism in aged women. The risk of hip fracture is significantly increased in aged women. Diagnosis of osteoporosis based on BMD of hip in aged women is more reliable.
