This study aimed to evaluate the knee osteoarthritis status among the population over age 50 in Kermanshah, Iran. The research community consisted of the population who has been visited in the health bus in Kermanshah in 2016-2017, of which 589 were chosen by an available sampling method. A WOMAC questionnaire was used to determine the prevalence of knee osteoarthritis. The prevalence of knee stiffness rate after sitting, lying down, or resting during the day among women and men were 40.7% and 20.5%, respectively. According to the findings, the highest prevalence rate of knee pain was in subjects with a BMI higher than 30 (31.6%) and BMI 25\u201330 (24.5%). 39.2% of the subjects never experienced knee pain, 16.6% monthly, 13.4% once a week, 20.4% daily, and 10.4% of them had prolonged knee pain experience. The prevalence of gender-based knee pain was 60.5% among women and 38.6% among men. 30.5% of women and 61.4% of men never experienced knee pain.<\/jats:p>","DOI":"10.1155\/2021\/9809565","type":"journal-article","created":{"date-parts":[[2021,11,12]],"date-time":"2021-11-12T16:50:09Z","timestamp":1636735809000},"page":"1-8","source":"Crossref","is-referenced-by-count":10,"title":["The Survey of Knee Osteoarthritis in the Population over Age 50 Visited in the Health Bus in Kermanshah, Iran"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6009-7439","authenticated-orcid":true,"given":"MohammadBagher","family":"Shamsi","sequence":"first","affiliation":[{"name":"School of Allied Medical Sciences, Kermanshah University of Medical Sciences, Kermanshah, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0042-0422","authenticated-orcid":true,"given":"Ameneh","family":"Safari","sequence":"additional","affiliation":[{"name":"Esfarayen Faculty of Medical Sciences, Esfarayen, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4791-4320","authenticated-orcid":true,"given":"Ali","family":"Soroush","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Kermanshah University of Medical Sciences, Kermanshah, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6763-5225","authenticated-orcid":true,"given":"Yahya","family":"Safari","sequence":"additional","affiliation":[{"name":"School of Allied Medical Sciences, Kermanshah University of Medical Sciences, Kermanshah, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1590\/s0102-311x2007000500017"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2012.04.023"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.322.7294.1079"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1111\/1756-185X.12883"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/keu409"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1097\/00029330-200609020-00004"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.ctcp.2016.01.001"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ctcp.2015.08.002"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2014.07.015"},{"issue":"8","key":"10","first-page":"1484","article-title":"Rheumatic diseases in China: ILAR-China study comparing the prevalence of rheumatic symptoms in northern and southern rural populations","volume":"21","author":"R.
