Using long\u2010term national cancer registry data in Denmark we examined incidence trends of iP\u2010SCC. Furthermore, we examined the relation between marital status, cohabitation status and risk of iP\u2010SCC using hazard ratios (HRs) with 95% confidence intervals (CIs) obtained in Cox proportional hazards regression analyses as our measure of relative risk. Overall, 1,292 cases of iP\u2010SCC were identified during 65.6 million person\u2010years of observation between 1978 and 2010. During this period, the WHO world age\u2010standardized incidence remained relatively stable (<jats:italic>p<\/jats:italic>\u2010trend\u2009=\u20090.41) with an average incidence of 1.05 cases per 100,000 person\u2010years. When compared to married men, those who were unmarried (HR 1.37; 95% CI: 1.13\u20131.66), divorced (HR 1.49; 95% CI: 1.24\u20131.79) or widowed (HR 1.36; 95% CI: 1.13\u20131.63) were at increased risk of iP\u2010SCC. Regarding cohabitation status, single\u2010living men were at increased risk of iP\u2010SCC compared to men in opposite\u2010sex cohabitation (HR 1.43; 95% CI: 1.26\u20131.62). Risk increased with increasing numbers of prior opposite\u2010sex (<jats:italic>p<\/jats:italic>\u2010trend\u2009=\u20090.02) and same\u2010sex (<jats:italic>p<\/jats:italic>\u2010trend\u2009&lt;\u20090.001) cohabitations. In conclusion, single\u2010living Danish men and men who are not currently married are at increased risk of iP\u2010SCC, and the risk increases with the number of prior cohabitations, perhaps reflecting less stable sexual relations in these subgroups.<\/jats:p>","DOI":"10.1002\/ijc.28107","type":"journal-article","created":{"date-parts":[[2013,2,13]],"date-time":"2013-02-13T04:05:16Z","timestamp":1360728316000},"page":"1173-1179","source":"Crossref","is-referenced-by-count":21,"title":["Marriage, cohabitation and incidence trends of invasive penile squamous cell carcinoma in Denmark 1978\u20132010"],"prefix":"10.1002","volume":"133","author":[{"given":"Constance J.","family":"Ulff\u2010M\u00f8ller","sequence":"first","affiliation":[{"name":"Department of Epidemiology Research Statens Serum Institut DK\u20102300 Copenhagen S Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacob","family":"Simonsen","sequence":"additional","affiliation":[{"name":"Department of Epidemiology Research Statens Serum Institut DK\u20102300 Copenhagen S Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Morten","family":"Frisch","sequence":"additional","affiliation":[{"name":"Department of Epidemiology Research Statens Serum Institut DK\u20102300 Copenhagen S Denmark"},{"name":"Center for Sexology Research Department of Clinical Medicine, Aalborg University DK-9000 Aalborg Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,3,7]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00345-008-0302-z"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/acprof:oso\/9780195149616.003.0061"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.critrevonc.2004.09.006"},{"key":"e_1_2_5_5_1","first-page":"630","volume-title":"Cancer incidence in five continents, vol.
