Non-gout crystal arthropathy (ICD-10 codes M11.0\u2013M11.9) was subclassified in four different groups: calcium pyrophosphate crystal deposition related arthropathy (CPPD), unspecified non-gout arthropathies, chondrocalcinosis, and hydroxyapatite crystal deposition disease. The crude and age-adjusted point prevalence on December 31, 2014, and the cumulative incidence during 2014 were calculated for all non-gout crystal arthropathies, CPPD, and other unspecified non-gout arthropathies overall and in relation to occupation, income, and level of education.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>The crude 2014 point prevalence (95% CI) and 2014 cumulative incidence (95% CI) of all non-gout crystal arthropathies were 0.23% (0.23\u20130.24) and 21.5 (19\u201325) cases\/100,000 persons. Mean age (range) among all prevalent cases in 2014 was 71 (20\u2013102) years and 56% were males. The point prevalence and cumulative incidence of CPPD were 0.09% (0.08\u20130.09) and 8 (7\u201310)\/100,000 persons, respectively. The corresponding data for unspecified non-gout crystal deposition disease was 0.16% (0.16\u20130.17) and 15.6 (13\u201318)\/100,000 persons, respectively. The prevalence and incidence of CPPD and unspecified non-gout crystal arthropathies were slightly higher in men and increased with age irrespective of gender. Unspecified non-gout crystal arthropathy but not CPPD was less prevalent in persons with \u2265\u200915\u2009years of education, whereas there were no clear associations with occupation and income.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Conclusion<\/jats:title>\n<jats:p>The prevalence of all diagnosed non-gout crystal arthropathies was 0.23%, thus considerably less prevalent than gout in southern Sweden. CPPD and other unspecified non-gout crystal arthropathies are the predominant diagnoses, increasing with age and in men. With the exception for unspecified non-gout crystal arthropathies being inversely correlated to a higher level of education, no convincing association with the socioeconomic factors was found.<\/jats:p>\n<\/jats:sec>","DOI":"10.1186\/s13075-019-2077-6","type":"journal-article","created":{"date-parts":[[2019,12,17]],"date-time":"2019-12-17T14:02:31Z","timestamp":1576591351000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Prevalence and incidence of non-gout crystal arthropathy in southern Sweden"],"prefix":"10.1186","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3414-8073","authenticated-orcid":false,"given":"Mohaned","family":"Hameed","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandra","family":"Turkiewicz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Englund","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lennart","family":"Jacobsson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meliha C.","family":"Kapetanovic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2019,12,17]]},"reference":[{"issue":"4","key":"2077_CR1","doi-asserted-by":"publisher","first-page":"563","DOI":"10.1136\/ard.2010.139105","volume":"70","author":"W Zhang","year":"2011","unstructured":"Zhang W, Doherty M, Bardin T, et al.
