However, little is known about the sex differences in the natural history of anal HPV infection in a heterosexual population. From May 2014 to March 2016, perianal\/anal canal (PA) swab samples were collected semiannually from 2,302 heterosexual men and 2,371 heterosexual women aged 18\u201355\u2009years old in Liuzhou, China. The specimens were genotyped for HPV DNA by polymerase chain reaction. The incidence rate ratio (IRR) and clearance rate ratio (CRR) were used to analyze the sex differences of incidence and clearance by Poisson regression, respectively. The incidences of PA oncogenic HPV in men and women were 3.4 per 1,000 person\u2010months and 8.6 per 1,000 person\u2010months, respectively, with an IRR of 0.39 (95% confidence interval (CI), 0.29\u20130.54 for men <jats:italic>versus<\/jats:italic> women) (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001). The CRR of PA oncogenic HPV infection for men <jats:italic>versus<\/jats:italic> women was 1.54 (95% CI, 1.17\u20132.03) (<jats:italic>p<\/jats:italic>\u2009=\u20090.0022). At 12\u2009months, 44% (20\/45) of HPV 16\/18 infections among women remained positive, whereas no (0\/7) infections persisted among men (<jats:italic>p<\/jats:italic>\u2009=\u20090.0350). Both the higher incidence and slower clearance of anal carcinogenic HPV infection among women may lead to a higher burden of anal cancer among women than among men in a heterosexual population.<\/jats:p>","DOI":"10.1002\/ijc.32255","type":"journal-article","created":{"date-parts":[[2019,3,8]],"date-time":"2019-03-08T13:29:55Z","timestamp":1552051795000},"page":"807-816","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Sex
