A cross-sectional study was performed in Dona In\u00eas, Para\u00edba, Brazil between 2014 and 2015. A clinical examination, clinical photography and a questionnaire were applied to 201 extractive mining workers. The T-student\u2019s, ANOVA one-way, Fisher\u2019s exact and Pearson chi-squared tests were performed and the significance level was set at 5%. A high prevalence of actinic cheilitis was observed (38.8%). Length of occupational exposure to sunlight in months (169.63\u00b1112.68, p=0.002) was associated with actinic cheilitis. Most workers were Caucasian (p&lt;0.001) and aged 37.41\u00b112.15 years (p=0.004). The time of occupational exposure to sunlight was significant in relation to the following clinical features: atrophy (225.75\u00b197.31; p=0.024); blurred demarcation between the vermilion border of the lip and the skin (186.68\u00b1113.15; p=0.032); vertical fissures (210.09\u00b1123.07; p=0.046); white and red spotting (199.51\u00b191.80; p=0.004); hard consistency of the lip (225.81\u00b1122.34; p=0.012). A high prevalence of actinic cheilitis was found. Age and ethnicity were associated with the presence of AC. Severe clinical presentations of actinic cheilitis were found among participants who had worked for at least 185 months (approximately 15 years) exposed to the sun.<\/jats:p>","DOI":"10.1590\/0103-6440201801605","type":"journal-article","created":{"date-parts":[[2018,6,18]],"date-time":"2018-06-18T11:01:11Z","timestamp":1529319671000},"page":"214-221","source":"Crossref","is-referenced-by-count":7,"title":["Prevalence of and Factors Associated with Actinic Cheilitis in Extractive Mining Workers"],"prefix":"10.1590","volume":"29","author":[{"given":"Rafaelle Ferreira dos","family":"Santos","sequence":"first","affiliation":[{"name":"Universidade Estadual da Para\u00edba,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rog\u00e9ria Lucio de","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Universidade Estadual da Para\u00edba,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marina","family":"Gallottini","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rubens","family":"Caliento","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dmitry Jos\u00e9 de Santana","family":"Sarmento","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo,  Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2018,3]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"414","DOI":"10.1590\/S1678-77572008000600011","article-title":"p53 and MDM2 protein expression in actinic cheilitis","volume":"6","author":"Freitas MC","year":"2008","journal-title":"J Appl Oral Sci"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"292","DOI":"10.4317\/medoral.20297","article-title":"Value of videoroscopy in the detection of alterations od actinic cheilitis and the selection of biopsy areas","volume":"20","author":"Miranda AM","year":"2015","journal-title":"Med Oral Patol Oral Cir Bucal"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1111\/dth.12188","article-title":"Ingenol mebutate gel treatment for actinic cheilitis: report of four cases","volume":"28","author":"Barrado Sol\u00eds N","year":"2015","journal-title":"Dermatol Ther"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"357","DOI":"10.1007\/s10735-010-9297-z","article-title":"Accumulation of CD1a positive Langerhans cells and mast cells in actinic cheilitis","volume":"41","author":"Ara\u00fajo CP","year":"2010","journal-title":"J Mol Histol"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"466","DOI":"10.1111\/ijd.12332","article-title":"Actinic cheilitis: clinicopathologic profile and association with degree of dysplasia","volume":"53","author":"Sarmento DJS","year":"2014","journal-title":"Int J Dermatol"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"173","DOI":"10.1016\/j.jaad.2011.09.040","article-title":"Solar cheilosis: an ominous precursor: part I.
