The study group comprised 144 men treated with total hip replacement due to hip osteoarthritis. We measured total, free, and bioavailable testosterone, estradiol, and sex-hormone-binding globulin (sex hormones), as well as parathyroid hormone, osteocalcin, carboxy terminal collagen crosslinks, and N-terminal propeptide of type I procollagen (markers of bone turnover). Total body BMD, BMC, total and visceral fat, and appendicular skeletal mass (ASM) were measured using dual-energy X-ray absorptiometry. ASM index, and total and visceral fat were positively correlated with BMD. Bone Zn correlated neither with sex hormones nor with bone turnover markers; however, it was positively associated both with BMD and with BMC, while bone Cu (as opposed to serum Cu) was not. In multiple regression, the ASM index, Zn\/Cu ratio (in both the serum and the bone), and serum Cu concentration were significantly associated with BMD and BMC after adjustment for age and body mass index (BMI). Our results suggest that the Zn\/Cu ratio in both the serum and the bone may exert a significant positive effect on total BMD and BMC.<\/jats:p>","DOI":"10.3390\/biom11020237","type":"journal-article","created":{"date-parts":[[2021,2,9]],"date-time":"2021-02-09T04:18:50Z","timestamp":1612844330000},"page":"237","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Bone Health in Aging Men: Does Zinc and Cuprum Level Matter?"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5954-4489","authenticated-orcid":false,"given":"Aleksandra","family":"Ry\u0142","sequence":"first","affiliation":[{"name":"Department of Medical Rehabilitation and Clinical Physiotherapy, Pomeranian Medical University, 71-210 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4819-9376","authenticated-orcid":false,"given":"Tomasz","family":"Miazgowski","sequence":"additional","affiliation":[{"name":"Department of Propedeutics of Internal Diseases and Arterial Hypertension, Pomeranian Medical University, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6105-5329","authenticated-orcid":false,"given":"Aleksandra","family":"Szyli\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Medical Rehabilitation and Clinical Physiotherapy, Pomeranian Medical University, 71-210 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agnieszka","family":"Turo\u0144-Skrzypi\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Medical Rehabilitation and Clinical Physiotherapy, Pomeranian Medical University, 71-210 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alina","family":"Jurewicz","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Traumatology and Orthopedic Oncology, Pomeranian Medical University, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrzej","family":"Bohatyrewicz","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Traumatology and Orthopedic Oncology, Pomeranian Medical University, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iwona","family":"Rotter","sequence":"additional","affiliation":[{"name":"Department of Medical Rehabilitation and Clinical Physiotherapy, Pomeranian Medical University, 71-210 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"110","DOI":"10.1016\/j.abb.2010.07.001","article-title":"Sex hormones and bone health in males","volume":"503","author":"Carnevale","year":"2010","journal-title":"Arch.
