title: Radial bone mineral content in healthy Mexican women.
abstract: Fifty healthy Mexican women from 21 to 70 years of age volunteered to undergo radial bone densitometry. The bone density in ten women per decade was assessed at two sites in the radius of the nondominant forearm; one site was the distal radius at 5 mm of separation from the ulna and the other at one-third of the distal radius. Calcium, inorganic phosphates and alkaline phosphatase were measured in serum samples and the calcium/creatinine ratio in fasting urine samples. Bone density at the distal radius was 360.6 +/- 36.2 mg/cm2, 369.8 +/- 47.9 mg/cm2 and 364.7 +/- 53.7 mg/cm2 in the 21-50 age group. There was no significant difference between these groups; the pooled value of all these samples was 365 +/- 46 mg/cm2. There was significant difference in the 51-60 age group, 290 +/- 48. mg/cm2 (p less than 0.01) and in the 61-70 age group. 277.9 +/- 49.9 mg/cm2 (p less than 0.01). Bone density at the one-third distal radius in the 21-20 age group was 696.3 +/- 60.9 mg/cm2; 31-40, 683.6 +/- 68.4 mg/cm2 and 41-50, 697.9 +/- 53.9 mg/cm2. There was no significant difference among these group; the pool of all these samples showed 692.6 +/- 59.6 mg/cm2. In the 51-60 age group it was 628.0 +/- 63.3 mg/cm2, a non significant difference. On the other hand, the density in the 61-70 group was 573.7 +/- 83.5 mg/cm2, significant (p less than 0.01) when compared to the 21-50 age group.(ABSTRACT TRUNCATED AT 250 WORDS)
