Participants (n = 153, 46% female; mean \u00b1 SD aged 38.9 \u00b1 8.0 years) were cluster-randomized (n = 18 work teams) to receive an organizational change intervention, with or without an activity tracker. A modified Nordic Musculoskeletal Questionnaire assessed pain intensity (0\u20139; none\u2013worst possible) in the neck, upper and lower back, upper and lower extremities, and in total. The activPAL3 (7 days, 24 h\/day protocol) measured sitting and prolonged sitting in \u226530 min bouts at work. Mixed models adjusting for cluster and intervention arm examined changes in pain (n = 104), and their associations with reductions in sitting and prolonged sitting (h\/10 h at work) (n = 90). Changes in pain were nonsignificant (p \u2265 0.05) and small for total pain (\u22120.06 [95% CI: \u22120.27, 0.16]) and for each body area (\u22120.26 [\u22120.66, 0.15] for upper back to 0.09 [\u22120.39, 0.56] for lower back). Sitting reduction was associated with reduced lower back pain (\u22120.84 [\u22121.44, \u22120.25] per hour, p = 0.005); other effects were small and non-significant. No substantial average changes in pain were seen; some improvement in lower back pain might be expected with larger sitting reductions. Larger samples and diverse interventions are required for more definitive evidence.<\/jats:p>","DOI":"10.3390\/ijerph15091975","type":"journal-article","created":{"date-parts":[[2018,9,10]],"date-time":"2018-09-10T10:28:57Z","timestamp":1536575337000},"page":"1975","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Evaluating Short-Term Musculoskeletal Pain Changes in Desk-Based Workers Receiving a Workplace Sitting-Reduction Intervention"],"prefix":"10.3390","volume":"15","author":[{"given":"Charlotte L.","family":"Brakenridge","sequence":"first","affiliation":[{"name":"School of Public Health, The University of Queensland, Brisbane, QLD 4006, Australia"},{"name":"RECOVER Injury Research Centre, The University of Queensland, Brisbane, QLD 4006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yee Ying","family":"Chong","sequence":"additional","affiliation":[{"name":"School of Public Health, The University of Queensland, Brisbane, QLD 4006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisabeth A.H.","family":"Winkler","sequence":"additional","affiliation":[{"name":"School of Public Health, The University of Queensland, Brisbane, QLD 4006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nyssa T.","family":"Hadgraft","sequence":"additional","affiliation":[{"name":"School of Public Health, The University of Queensland, Brisbane, QLD 4006, Australia"},{"name":"Centre for Urban Transitions, Swinburne University of Technology, Melbourne, VIC 3122, Australia"},{"name":"Baker Heart and Diabetes Institute, Melbourne, VIC 3004, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brianna S.","family":"Fjeldsoe","sequence":"additional","affiliation":[{"name":"School of Public Health, The University of Queensland, Brisbane, QLD 4006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0911-0866","authenticated-orcid":false,"given":"Venerina","family":"Johnston","sequence":"additional","affiliation":[{"name":"RECOVER Injury Research Centre, The University of Queensland, Brisbane, QLD 4006, Australia"},{"name":"School of Health and Rehabilitation Sciences, The University of Queensland, Brisbane, QLD 4072, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7786-4128","authenticated-orcid":false,"given":"Leon M.","family":"Straker","sequence":"additional","affiliation":[{"name":"School of Physiotherapy and Exercise Science, Curtin University, Perth, WA 6102, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Genevieve N.","family":"Healy","sequence":"additional","affiliation":[{"name":"School of Public Health, The University of Queensland, Brisbane, QLD 4006, Australia"},{"name":"Baker Heart and Diabetes Institute, Melbourne, VIC 3004, Australia"},{"name":"School of Physiotherapy and Exercise Science, Curtin University, Perth, WA 6102, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7527-4311","authenticated-orcid":false,"given":"Bronwyn K.","family":"Clark","sequence":"additional","affiliation":[{"name":"School of Public Health, The University of Queensland, Brisbane, QLD 4006, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,9,10]]},"reference":[{"key":"ref_1","first-page":"646","article-title":"Burden of major musculoskeletal conditions","volume":"81","author":"Woolf","year":"2003","journal-title":"Bull.
