These communities are inhabited by low-income people, and are accessible only by small boats. Cervical cytology and risk factors for HPV infection were also assessed.<\/jats:p><jats:p>\n            Methods\u2003Cervical samples from 353 women of selected communities were collected both for Papanicolau (Pap) test and HPV detection. Conventional polymerase chain reaction (PCR) and real-time PCR were used to assess the overall and type-specific prevalence of HPV-16 and HPV-18, the main oncogenic types worldwide. Epidemiological questionnaires were used for the assessment of the risk factors for HPV infection.<\/jats:p><jats:p>\n            Results\u2003The mean age of the participants was 37 years (standard deviation [SD]\u2009\u00b1\u200913.7). Most were married or with a fixed sexual partner (79%), and had a low educational level (80%) and family monthly income (&lt; U$ 250; 53%). Overall, HPV prevalence was 16.4% (n\u2009=\u200958), with 8 cases of HPV-16 (2.3%) and 5 of HPV-18 (1.4%). Almost 70% of the women surveyed had never undergone the Pap test. Abnormal cytology results were found in 27.5% (n\u2009=\u200997) of the samples, with higher rates of HPV infection according to the severity of the lesions (p\u2009=\u20090.026).<\/jats:p><jats:p>\n            Conclusions\u2003The infections by HPV-16 and HPV-18 were not predominant in our study, despite the high prevalence of overall HPV infection. Nevertheless, the oncogenic potential of these types and the low coverage of the Pap test among women from riverside communities demonstrate a potential risk for the development of cervical lesions and their progression to cervical cancer, since the access to these communities is difficult and, in most cases, these women do not have access to primary care and public health services.<\/jats:p>","DOI":"10.1055\/s-0037-1604027","type":"journal-article","created":{"date-parts":[[2017,6,28]],"date-time":"2017-06-28T23:25:37Z","timestamp":1498692337000},"page":"350-357","source":"Crossref","is-referenced-by-count":13,"title":["Prevalence of Human Papillomavirus Infection and Cervical Cancer Screening among Riverside Women of the Brazilian Amazon"],"prefix":"10.61622","volume":"39","author":[{"given":"Daniel Valim","family":"Duarte","sequence":"additional","affiliation":[{"name":"Molecular and Celular Biology Laboratory, N\u00facleo de Medicina Tropical, Universidade Federal do Par\u00e1, Bel\u00e9m, Par\u00e1, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo Covre","family":"Vieira","sequence":"additional","affiliation":[{"name":"Molecular and Celular Biology Laboratory, N\u00facleo de Medicina Tropical, Universidade Federal do Par\u00e1, Bel\u00e9m, Par\u00e1, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elza Ba\u00eda de","family":"Brito","sequence":"additional","affiliation":[{"name":"Citopathology Laboratory, N\u00facleo de Medicina Tropical, Universidade Federal do Par\u00e1, Bel\u00e9m, Par\u00e1, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria da Concei\u00e7\u00e3o Nascimento","family":"Pinheiro","sequence":"additional","affiliation":[{"name":"Human and Environmental Toxicology Laboratory, N\u00facleo de Medicina Tropical, Universidade Federal do Par\u00e1, Bel\u00e9m, Par\u00e1, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeniffer do Socorro Valente","family":"Monteiro","sequence":"additional","affiliation":[{"name":"Molecular and Celular Biology Laboratory, N\u00facleo de Medicina Tropical, Universidade Federal do Par\u00e1, Bel\u00e9m, Par\u00e1, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M\u00e1rio Diego Rocha","family":"Valente","sequence":"additional","affiliation":[{"name":"Departament of Education, Departamento de Tr\u00e2nsito do Par\u00e1, Bel\u00e9m, Par\u00e1, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edna Aoba Yassui","family":"Ishikawa","sequence":"additional","affiliation":[{"name":"Molecular and Celular Biology Laboratory, N\u00facleo de Medicina Tropical, Universidade Federal do Par\u00e1, Bel\u00e9m, Par\u00e1, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hellen Thais","family":"Fuzii","sequence":"additional","affiliation":[{"name":"Immunopathology Laboratory, N\u00facleo de Medicina Tropical, Universidade Federal do Par\u00e1, Bel\u00e9m, Par\u00e1, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ma\u00edsa Silva de","family":"Sousa","sequence":"additional","affiliation":[{"name":"Molecular and Celular Biology Laboratory, N\u00facleo de Medicina Tropical, Universidade Federal do Par\u00e1, Bel\u00e9m, Par\u00e1, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"47794","published-online":{"date-parts":[[2017,6,28]]},"reference":[{"issue":"01","key":"ref1","doi-asserted-by":"crossref","first-page":"11","DOI":"10.1016\/S1470-2045(01)00617-9","article-title":"Persistent human papillomavirus infection and cervical neoplasia","volume":"3","author":"A Ferenczy","year":"2002","journal-title":"Lancet Oncol"},{"issue":"07","key":"ref2","doi-asserted-by":"crossref","first-page":"453","DOI":"10.1016\/S1473-3099(07)70158-5","article-title":"Worldwide prevalence and genotype distribution of cervical human papillomavirus DNA in women with normal cytology: a meta-analysis","volume":"7","author":"S de Sanjos\u00e9","year":"2007","journal-title":"Lancet Infect Dis"},{"issue":"04","key":"ref3","doi-asserted-by":"crossref","first-page":"699","DOI":"10.1158\/1055-9965.EPI-10-1108","article-title":"Early natural history of incident, type-specific human papillomavirus infections in newly sexually active young women","volume":"20","author":"R L Winer","year":"2011","journal-title":"Cancer Epidemiol Biomarkers Prev"},{"issue":"04","key":"ref4","first-page":"349","article-title":"Cervical cancer in the asian pacific-epidemiology, screening and treatment","volume":"5","author":"M A Moore","year":"2004","journal-title":"Asian Pac J Cancer Prev"},{"key":"ref5","volume-title":"Minist\u00e9rio da Sa\u00fade.
