Bone mineral density in XXXX : comparison with @entity309 and healthy controls.

@entity1 @entity66 @entity170 @entity1252 @entity228 @entity79 @entity309
OBJECTIVES: To examine @entity79 ( @entity79 ) frequency of @entity170 and reduced bone mass in @entity1252 ( @entity1252 ), and compare the data of the @entity1252 @entity1 with matched @entity309 ( @entity309 ) @entity1 and healthy controls. Secondly, to study possible correlations between @entity79 , @entity66 variables in the @entity1252 @entity1 . METHODS: Measures of @entity79 assessed by dual energy x ray absorptiometry were obtained from 75 @entity1252 @entity1 aged </= 70 years, 75 @entity309 @entity1 matched for age, sex and disease duration, and from 75 healthy controls matched for age, sex and geographical area. Disease activity and accumulated organ damage were assessed in the @entity1252 @entity1 . RESULTS: The @entity1252 @entity1 had significantly lower @entity79 values at lumbar spine L2-L4 and hip, and higher frequency of @entity170 at all sites of measurement compared with matched healthy controls. The matched @entity1252 and @entity309 @entity1 had similar @entity79 , prevalence of @entity170 and reduced bone mass. In the @entity1252 @entity1 @entity79 was more strongly correlated with accumulated organ damage than with markers of disease activity or duration. In multivariate analyses @entity79 was at all sites predicted by age and body mass, at lumbar spine also by the current @entity228 dose. CONCLUSION: The study showed reduced @entity79 in @entity1 with @entity1252 compared with matched healthy controls. Premenopausal @entity1 taking corticosteroids were especially affected. Furthermore, the @entity79 of matched @entity1252 and @entity309 @entity1 was reduced to a similar extent.
