In this manuscript, three acute LBP severity categorization definitions were used based on LBP frequency combined with either 1) pain impact frequency (impact-based) or 2) pain intensity (intensity-based), as well as LBP pain interference frequency (interference only-based) severity categories. The purpose of this manuscript is to describe and then compare these acute LBP severity groups in the following characteristics: 1) sociodemographic, 2) general and physical health, and 3) psychological. This cross-sectional study used baseline data from 131 community-based participants with acute LBP (&lt;4 weeks duration before screening and \u226530 pain-free days before acute LBP onset). Descriptive associations were calculated as prevalence ratios for categorical variables and Hedges\u2019\n                  <jats:italic>g<\/jats:italic>\n                  for continuous variables. Our analyses identified several large associations for impact-based and intensity-based categories with global mental health, global physical health, STarT Back Screening Tool risk category, and general health. Larger associations were found with social constructs (racially and ethnically minoritized, performance of social roles, and isolation) when using the intensity-based versus impact-based categorization. The interference-based category did not capture as much variability between acute LBP severity categories. This study adds to the literature by providing standard ways to characterize community-based individuals experiencing acute LBP. The robust differences observed between these categorization approaches suggest that how we define acute LBP severity is consequential; these different approaches may be used to improve the early identification of factors potentially contributing to the development of chronic LBP.\n                <\/jats:p>","DOI":"10.1101\/2023.10.02.23296149","type":"posted-content","created":{"date-parts":[[2023,10,3]],"date-time":"2023-10-03T23:45:22Z","timestamp":1696376722000},"source":"Crossref","is-referenced-by-count":1,"title":["Characterizing Acute Low Back Pain in a Community-Based Cohort"],"prefix":"10.64898","author":[{"given":"Colleen","family":"Burke","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3205-9280","authenticated-orcid":false,"given":"Kenneth A.","family":"Taylor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca","family":"Fillipo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven Z.","family":"George","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Flavia P.","family":"Kapos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephanie","family":"Danyluk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carla A.","family":"Kingsbury","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kelley","family":"Seebeck","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher E.","family":"Lewis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily","family":"Ford","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cecilia","family":"Plez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrzej S.","family":"Kosinski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael C.","family":"Brown","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam P.","family":"Goode","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2024032523151059000_2023.10.02.23296149v2.1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(17)30569-X"},{"issue":"1","key":"2024032523151059000_2023.10.02.23296149v2.2","doi-asserted-by":"crossref","first-page":"16","DOI":"10.1002\/acr2.1002","article-title":"Race\/Ethnicity Moderates the Association Between Psychosocial Resilience and Movement-Evoked Pain in Knee Osteoarthritis","volume":"1","year":"2019","journal-title":"ACR Open Rheumatol"},{"issue":"5","key":"2024032523151059000_2023.10.02.23296149v2.3","doi-asserted-by":"crossref","first-page":"e0178043","DOI":"10.1371\/journal.pone.0178043","article-title":"Transgender-inclusive measures of sex\/gender for population surveys: Mixed-methods evaluation and recommendations","volume":"12","year":"2017","journal-title":"PLoS One"},{"key":"2024032523151059000_2023.10.02.23296149v2.4","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a112674"},{"issue":"4","key":"2024032523151059000_2023.10.02.23296149v2.5","first-page":"458","article-title":"The Measurement to Understand Reclassification of Disease of Cabarrus\/Kannapolis (MURDOCK) Study Community Registry and Biorepository","volume":"4","year":"2012","journal-title":"Am J Transl Res"},{"key":"2024032523151059000_2023.10.02.23296149v2.6","doi-asserted-by":"crossref","unstructured":"Black C , Cerdena JP , Spearman-McCarthy EV .
