However, the effects of pre-existing musculoskeletal pain on the development of shoulder pain are not clear. The present study aimed to elucidate the association between coexisting musculoskeletal pain at other body sites and new-onset shoulder pain among survivors of the Great East Japan Earthquake (GEJE).<\/jats:p>\n <\/jats:sec>\n \n Design<\/jats:title>\n This is a longitudinal study.<\/jats:p>\n <\/jats:sec>\n \n Setting<\/jats:title>\n The study was conducted at the severely damaged coastal areas in Ishinomaki and Sendai cities.<\/jats:p>\n <\/jats:sec>\n \n Participants<\/jats:title>\n The survivors who did not have shoulder pain at 3 years after the GEJE were followed up 1\u2009year later (n=2131).<\/jats:p>\n <\/jats:sec>\n \n Interventions<\/jats:title>\n Musculoskeletal pain (low back, hand and\/or foot, knee, shoulder and neck pain) was assessed using self-reported questionnaires.<\/jats:p>\n <\/jats:sec>\n \n Main outcome measures<\/jats:title>\n The outcome of interest was new-onset shoulder pain, which was defined as shoulder pain absent at 3 years but present at 4 years after the disaster. The main predictive factor for new-onset shoulder pain was musculoskeletal pain in other body parts at 3 years after the GEJE; this was categorised according to the number of pain sites (0, 1, \u22652). Multiple regression analyses were conducted to calculate the odds ratio (OR) and 95% confidence interval (CI) for new-onset shoulder pain due to musculoskeletal pain in other body parts.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The incidence of new-onset shoulder pain was 6.7% (143\/2131). Musculoskeletal pain in other body parts was significantly associated with new-onset shoulder pain. Using the survivors without other musculoskeletal pain as reference, the adjusted OR and 95%\u2009CI for new-onset shoulder pain were 1.86 (1.18 to 2.94) for those with one body part and 3.22 (2.08 to 4.98) for those with \u22652\u2009body parts presenting with musculoskeletal pain (p<0.001).<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Pre-existing musculoskeletal pain in other body parts was significantly associated with new-onset shoulder pain among survivors; this provides useful information for clinical and public health policies.<\/jats:p>\n <\/jats:sec>","DOI":"10.1136\/bmjopen-2020-041804","type":"journal-article","created":{"date-parts":[[2021,2,15]],"date-time":"2021-02-15T20:20:19Z","timestamp":1613420419000},"page":"e041804","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Association of musculoskeletal pain in other body parts with new-onset shoulder pain: a longitudinal study among survivors of the Great East Japan Earthquake"],"prefix":"10.1136","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2992-2178","authenticated-orcid":false,"given":"Yoshihiro","family":"Hagiwara","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Tohoku University School of Medicine, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yutaka","family":"Yabe","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tohoku University School of Medicine, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4642-854X","authenticated-orcid":false,"given":"Takuya","family":"Sekiguchi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tohoku University School of Medicine, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0197-6772","authenticated-orcid":false,"given":"Yumi","family":"Sugawara","sequence":"additional","affiliation":[{"name":"Division of of Epidemiology, Department of Health Informatics and Public Health, Tohoku University Graduate School of Public Health, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Tsuchiya","sequence":"additional","affiliation":[{"name":"Department of Nursing, Faculty of Health Science, Tohoku Fukushi University, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinichirou","family":"Yoshida","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tohoku University School of Medicine, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takahiro","family":"Onoki","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tohoku University School of Medicine, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tadahisa","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tohoku University School of Medicine, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Iwatsu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tohoku University School of Medicine, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ichiro","family":"Tsuji","sequence":"additional","affiliation":[{"name":"Division of of Epidemiology, Department of Health Informatics and Public Health, Tohoku University Graduate School of Public Health, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eiji","family":"Itoi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Tohoku University School of Medicine, Sendai, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,2,15]]},"reference":[{"key":"2025101810260064000_11.2.e041804.1","unstructured":"Reconstruction .
