Prevalência de queilite actínica em trabalhadores expostos à radiação solar no município de Patos - PB.

Abstract

Prevalence of actinic cheilitis in workers exposed to solar radiation in the city of Patos - PB. Actinic cheilitis is a potentially malignant lesion lip, especially in the lower lip, whose etiology is ultraviolet radiation. Outdoor workers are considered those on a normal working day, have your outdoor functions for more than three hours and are considered strong candidates to develop actinic cheilitis. This work aimed to study the prevalence of actinic cheilitis in outdoor workers in the city of Patos, state of Paraíba, Brazil, and possible associations of the presence of actinic cheilitis and your severity with sociodemographic and epidemiology. Only workers above age 18 participated in the study. Data collection took place through extra-oral examination and a standard questionnaire with questions that characterized socioeconomic and demographic factors, occupational exposure and habits. The sample consisted of 151 individuals, where the prevalence of actinic cheilitis was 29.1%, the most prevalent male (71.5%), brown-skinned (52.3%) and the mean age was 39.18 years ( SD ± 14.7). Most workers had low education (44.4%), informal work (62.3%) and income was up to 1,500 reais (61.4%). The presence of actinic cheilitis showed statistical significant association with informal work (p = 0.003), income (p <0.001), the exposure time in weekdays (p = 0.011) and months (p = 0.033), and smoking (p = 0.001). The most severe lesions showed significance in relation with white skin (p = 0.001), low education (p = 0.029) and the non-use of cap and hat (p = 0.002). The conclusions of this study were that prevalence of actinic cheilitis was considered high, most of the workers exposed to ultraviolet radiation does not have adequate protection for lips and socio-economic and epidemiology are related to the presence of actinic cheilitis. It is therefore necessary public health programs to aware the dangers of exposure to solar radiation unsecured form.
