['GH deficiency (GHD) is associated with low bone mineral density (BMD). Risk factors for lower BMD in this GHD population have not been fully elucidated. In particular, there are limited published data in GH-naïve subjects.', 'The objective of the study was to identify endocrine correlates of low BMD in treatment-naïve adult GHD subjects.', 'This was a retrospective analysis of data extracted from the (Pfizer International Metabolic Study) KIMS database.', 'The study was an international epidemiological survey of more than 15,000 adult GHD patients from 31 countries.', 'A total of 1218 subjects with stringently defined GHD of adult onset (641 women and 577 men) who were GH naïve and had BMD measured in the posterior anterior lumbar spine and femoral neck by dual-energy X-ray absorptiometry.', 'Variables associated with standardized BMD (sBMD) in adult-onset GHD were examined.', 'In the LS, body mass index (r = 0.13, P < 0.01), unreplaced sex steroid deficiency (r = -0.17, P < 0.0001), and corticotropin deficiency (r = -0.11, P < 0.01) were independently associated with sBMD. In the FN, age (r = -0.19, P < 0.0001), female gender (r = -0.18, P < 0.0001), body mass index (r = 0.21, P < 0.0001), and decreased IGF-I SD scores (r = 0.10, P < 0.001) were independently associated with sBMD.'] Are unreplaced sex steroid deficiency , corticotropin deficiency , and lower IGF-I associated with lower bone mineral density in adults with growth hormone deficiency : a KIMS database analysis?
