Bone mineral content in Polynesian and white New Zealand women.

Abstract

The forearm bone mineral content of Polynesian and European women in New Zealand was measured to assess whether the inter-racial differences found in other populations also occurred in these two groups. The bone mineral content of the nondominant distal radius and ulna was measured by single photon absorptiometry in 123 European and 80 Polynesian women. The mean values were about 20% higher in Polynesians than in Europeans. The reason for this difference in bone mineral content is unknown but the findings do show that high bone density is not confined to African races and that inter-racial differences in bone mineral content may be more common than has been thought hitherto.
