Few comprehensive studies have examined correlates of vBMD in older men. This study evaluated the impact of demographic, anthropometric, lifestyle, and medical factors on vBMD in 1172 men aged 69 to 97 years and enrolled in the Osteoporotic Fractures in Men Study (MrOS). Peripheral quantitative computed tomography (pQCT) was used to measure vBMD of the radius and tibia. The multivariable linear regression models explained up to 10% of the variance in trabecular vBMD and up to 9% of the variance in cortical vBMD. Age was not correlated with radial trabecular vBMD. Correlates associated with both cortical and trabecular vBMD were age (\u2212), caffeine intake (\u2212), total calcium intake (+), nontrauma fracture (\u2212), and hypertension (+). Higher body weight was related to greater trabecular vBMD and lower cortical vBMD. Height (\u2212), education (+), diabetes with thiazolidinedione (TZD) use (+), rheumatoid arthritis (+), using arms to stand from a chair (\u2212), and antiandrogen use (\u2212) were associated only with trabecular vBMD. Factors associated only with cortical vBMD included clinic site (\u2212), androgen use (+), grip strength (+), past smoker (\u2212), and time to complete five chair stands (\u2212). Certain correlates of trabecular and cortical vBMD differed among older men. An ascertainment of potential risk factors associated with trabecular and cortical vBMD may lead to better understanding and preventive efforts for osteoporosis in men. \u00a9 2010 American Society for Bone and Mineral Research<\/jats:p>","DOI":"10.1002\/jbmr.6","type":"journal-article","created":{"date-parts":[[2010,2,1]],"date-time":"2010-02-01T06:49:17Z","timestamp":1265006957000},"page":"1017-1028","source":"Crossref","is-referenced-by-count":31,"title":["Correlates of trabecular and cortical volumetric bone mineral density of the radius and tibia in older men: The osteoporotic fractures in men study"],"prefix":"10.1093","volume":"25","author":[{"given":"Kamil E","family":"Barbour","sequence":"first","affiliation":[{"name":"Department of Epidemiology, Graduate School of Public Health, University of Pittsburgh, Pittsburgh, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph M","family":"Zmuda","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Graduate School of Public Health, University of Pittsburgh, Pittsburgh, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elsa S","family":"Strotmeyer","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Graduate School of Public Health, University of Pittsburgh, Pittsburgh, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mara J","family":"Horwitz","sequence":"additional","affiliation":[{"name":"Division of Endocrinology and Metabolism, University of Pittsburgh School of Medicine, Pittsburgh, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Boudreau","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Graduate School of Public Health, University of Pittsburgh, Pittsburgh, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rhobert W","family":"Evans","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Graduate School of Public Health, University of Pittsburgh, Pittsburgh, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristine E","family":"Ensrud","sequence":"additional","affiliation":[{"name":"Department of Rheumatology, Minneapolis VA Medical Center, Minneapolis, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moira A","family":"Petit","sequence":"additional","affiliation":[{"name":"School of Kinesiology, University of Minnesota, Minneapolis, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher L","family":"Gordon","sequence":"additional","affiliation":[{"name":"Department of Radiology, McMaster University, Hamilton, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jane A","family":"Cauley","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Graduate School of Public Health, University of Pittsburgh, Pittsburgh, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"for the Osteoporotic Fractures in Men (MrOS) Research Group","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2010,4,30]]},"reference":[{"key":"2024020320154177900_bib1","doi-asserted-by":"crossref","first-page":"1525","DOI":"10.1007\/s00198-005-1866-8","article-title":"Factors associated with the lumbar spine and proximal femur bone mineral density in older men","volume":"16","author":"Cauley","year":"2005","journal-title":"Osteoporos Int."},{"key":"2024020320154177900_bib2","doi-asserted-by":"crossref","first-page":"441","DOI":"10.1210\/er.2008-0002","article-title":"Osteoporosis in men","volume":"29","author":"Khosla","year":"2008","journal-title":"Endocr Rev."},{"key":"2024020320154177900_bib3","doi-asserted-by":"crossref","first-page":"886","DOI":"10.1002\/jbmr.5650070902","article-title":"How many women have osteoporosis?
