People with COVID-19 are at higher risk of physical and mental health conditions, which could impact bone health. The aim of this review was to explore the effects of COVID-19 on BMD, BTMs, and joints. An electronic search of the PubMed, Web of Science, Scopus, and Ovid Medline databases considered studies published between 1 January 2020 and 1 November 2023. The search was limited to English, original studies in adult humans. The title and abstract of the identified papers were screened, followed by a full-text review using inclusion and exclusion criteria. The data extracted included the study and participant characteristics, BTMs, BMD, and joint abnormalities. The Newcastle\u2013Ottawa scale quality assessment tool was used to assess the risk of bias. Five studies involving 305 out of 495 infected individuals observed a reduced BMD after COVID-19, with the most significant reduction occurring a year later. Both bone resorption and bone formation markers decreased, while regulatory markers showed higher levels in infected patients. COVID-19 may harm bone health by increasing bone regulatory markers and reducing bone formation and absorption, leading to a lower BMD. Elderly, frail, and osteopenic or osteoporotic individuals are at higher risk and should be regularly monitored for bone loss if they have long COVID.<\/jats:p>","DOI":"10.3390\/v16111694","type":"journal-article","created":{"date-parts":[[2024,10,30]],"date-time":"2024-10-30T12:25:39Z","timestamp":1730291139000},"page":"1694","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Bone Mineral Density, Bone Biomarkers, and Joints in Acute, Post, and Long COVID-19: A Systematic Review"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3612-9474","authenticated-orcid":false,"given":"Fahad","family":"Alghamdi","sequence":"first","affiliation":[{"name":"College of Medicine and Health, University of Exeter, Exeter EX2 4TH, UK"},{"name":"Department of Radiologic Technology, College of Applied Medical Sciences, Qassim University, Buraydah 52571, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3896-2542","authenticated-orcid":false,"given":"Kinan","family":"Mokbel","sequence":"additional","affiliation":[{"name":"College of Medicine and Health, University of Exeter, Exeter EX2 4TH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2120-8877","authenticated-orcid":false,"given":"Robert","family":"Meertens","sequence":"additional","affiliation":[{"name":"College of Medicine and Health, University of Exeter, Exeter EX2 4TH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8818-032X","authenticated-orcid":false,"given":"Abasiama Dick","family":"Obotiba","sequence":"additional","affiliation":[{"name":"College of Medicine and Health, University of Exeter, Exeter EX2 4TH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mansour","family":"Alharbi","sequence":"additional","affiliation":[{"name":"PACS Admin, Radiology Department, King Khalid Hospital in Kharij, Riyadh 11942, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7360-0926","authenticated-orcid":false,"given":"Karen M.","family":"Knapp","sequence":"additional","affiliation":[{"name":"College of Medicine and Health, University of Exeter, Exeter EX2 4TH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6826-418X","authenticated-orcid":false,"given":"William David","family":"Strain","sequence":"additional","affiliation":[{"name":"College of Medicine and Health, University of Exeter, Exeter EX2 4TH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1017","DOI":"10.1038\/s41591-020-0968-3","article-title":"Extrapulmonary manifestations of COVID-19","volume":"26","author":"Gupta","year":"2020","journal-title":"Nat.
