This study\u2019s aim was to assess the relationship between sociodemographic and physical functioning variables and the presence of individual musculoskeletal disorders (MSDs), MSD comorbidity, and multimorbidity, as well as to determine factors that are independent predictors of the presence of MSDs in people over 65 years old. Methods: This population-based study included 3701 participants aged 65 years and older. Data on individual MSDs addressed cervical and lumbosacral spine regions and degenerative joint disease (arthrosis). The subjects were categorized into four groups: those without any diseases; those with one MSD; those with two MSDs (comorbidities); and those with three MSDs (multimorbidities). The sociodemographic and physical functioning variables were analyzed. Results: Females were more likely to have MSDs (two: OR 1.95 and three: OR 2.25) than men. Elderly people aged 75 and above were 1.49 times more likely to have three MSDs. Elderly people with elementary school education were more likely to have MSDs (two: OR 1.34 and three: OR 2.06) than those with high school\/university education. The low-income population was 2.47 times more likely to have three MSDs. Individuals with partial activity limitations because of health problems had greater chances of having one, two, or three MSDs (OR 1.60, 1.59, and 1.94, respectively), and elderly individuals with severe limitations had an OR of 1.43, 2.17, and 4.12, respectively. Individuals with some\/many difficulties in walking up or down 12 steps were more likely to have MSDs (two: OR 2.26 and three: OR 2.28). Conclusions: The significant predictors of experiencing a single MSD, MSD comorbidity, or MSD multimorbidity include residing in the Serbian capital city and having limitations in activities due to health problems. A significant predictor of having a single MSD or MSD comorbidity is residing in the northern region of Serbia. A significant predictor of MSD comorbidity is residing in the southeastern region of Serbia. Significant predictors of MSD comorbidity or MSD multimorbidity include female gender, an elementary school educational level, and experiencing difficulty in walking up or down 12 steps. Significant predictors of MSD multimorbidity are being 75 years of age and above and having a lower income.<\/jats:p>","DOI":"10.3390\/jcm13216541","type":"journal-article","created":{"date-parts":[[2024,11,1]],"date-time":"2024-11-01T11:53:43Z","timestamp":1730462023000},"page":"6541","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unlocking the Potential of the Elderly Population in Serbia: A Modeling Study on Musculoskeletal Disorders and Associated Factors"],"prefix":"10.3390","volume":"13","author":[{"given":"Diana","family":"Radovic","sequence":"first","affiliation":[{"name":"Institute of Rehabilitation, 11000 Belgrade, Serbia"},{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0684-359X","authenticated-orcid":false,"given":"Milena","family":"Santric-Milicevic","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"},{"name":"Laboratory for Strengthening Capacity and Performance of Health System and Workforce for Health Equity, Institute of Social Medicine, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0609-9916","authenticated-orcid":false,"given":"Dejan","family":"Nikolic","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"},{"name":"Department of Physical Medicine and Rehabilitation, University Children\u2019s Hospital, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0388-3825","authenticated-orcid":false,"given":"Tamara","family":"Filipovic","sequence":"additional","affiliation":[{"name":"Institute of Rehabilitation, 11000 Belgrade, Serbia"},{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jovan","family":"Ducic","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ljubica","family":"Nikcevic","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"},{"name":"Special Hospital for Cerebrovascular Disorders \u201cSveti Sava\u201d, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Milica","family":"Jovicic","sequence":"additional","affiliation":[{"name":"Institute of Rehabilitation, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5648-6762","authenticated-orcid":false,"given":"Ivan","family":"Tulic","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"},{"name":"Institute for Orthopaedic Surgery and Traumatology, University Clinical Center of Serbia, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4988-341X","authenticated-orcid":false,"given":"Goran","family":"Tulic","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Belgrade, 11000 Belgrade, Serbia"},{"name":"Institute for Orthopaedic Surgery and Traumatology, University Clinical Center of Serbia, 11000 Belgrade, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,31]]},"reference":[{"key":"ref_1","unstructured":"United Nations, Department of Economic and Social Affairs, Population Division (2024, July 23).
