Comprehensive literature searches in Medline-PubMed, Embase and SCOPUS databases. Original studies published between 2009 and 2019 with a cross-sectional design were included. The quality of the studies was assessed with Critical Appraisal Checklist for Studies Reporting Prevalence Data from the Joanna Briggs Institute. Protocol registered in the International Prospective Register of Systematic Reviews with reference number: CRD42019137990.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Out of the 1,310 potential studies found, 25 studies fulfilled the inclusion criteria. Most of the studies were of high quality. High levels of heterogeneity were found in the studies included. In the general population, the prevalence of long-term opioid use was 2.3% (95% CI: 1.5\u20133.6%), the prevalence of short-term opioid use was 8.1% (95% CI: 5.6\u201311.6%), and among people with chronic low back pain it was 5.8% (95% CI: 0.5\u201345.5%). The prevalence of opioid use among patients from the health records or medical surveys was 41% (95% CI: 23.3\u201361.3%). Finally, in patients with musculoskeletal pain, the prevalence was 20.5% (95% CI: 12.9\u201330.9%) and in patients with fibromyalgia, 24.5% (95% CI: 22.9\u201326.2%). A higher prevalence of opioid use was observed among men, younger people, patients receiving prescriptions of different types of drugs, smokers and patients without insurance or with noncommercial insurance. In addition, non-white and Asian patients were less likely to receive opioids than non-Hispanic white patients.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    The prevalence of opioid use among patients with CNCP was higher in subjects with short or occasional use compared to those with long-term use. Men, younger people, more chronic pain conditions, and patients without insurance or with noncommercial insurance were most related to opioid use. However, non-white and Asian patients, and those treated by a physician trained in complementary medicine were less likely to use opioids.\n                  <\/jats:p>","DOI":"10.3389\/fphar.2020.564412","type":"journal-article","created":{"date-parts":[[2020,12,7]],"date-time":"2020-12-07T04:26:43Z","timestamp":1607315203000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":45,"title":["Prevalence of Therapeutic use of Opioids in Chronic non-Cancer Pain Patients and Associated Factors: A Systematic Review and Meta-Analysis"],"prefix":"10.3389","volume":"11","author":[{"given":"Helena","family":"De Sola","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda","family":"Due\u00f1as","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandro","family":"Salazar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia","family":"Ortega-Jim\u00e9nez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inmaculada","family":"Failde","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2020,11,18]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e012432","DOI":"10.1136\/bmjopen-2016-012432","article-title":"Evaluation of use and cost of medical care of common lumbar disorders in Korea: cross-sectional study of Korean Health Insurance Review and Assessment Service National Patient Sample data","volume":"6","author":"Ahn","year":"2016","journal-title":"BMJ Open"},{"key":"B2","doi-asserted-by":"publisher","first-page":"192","DOI":"10.1007\/s00586-006-1072-1","article-title":"Chapter 4: European guidelines for the management of chronic nonspecific low back pain","volume":"15","author":"Airaksinen","year":"2006","journal-title":"Eur.
