Prevalence and factors associated with oral potentially malignant disorders in Brazil's rural workers

Abstract

Rural workers showed high vulnerability to the presence of OPMDs, as estimated prevalence exhibited was high.

Actinic Cheilitis Prevalence and Risk Factors: A Cross-sectional, Multicentre Study in a Population Aged 45 Years and Over in North-west Spain

“…Significant association with ageing has been present in other studies (19,21,22) confirming that accumulation of sun exposure is the main risk factor for AC. This statement is further corroborated by the significant correlation between AC and outdoor working for more than 25 years (OR 7.14), being the relation with accumulated time of UV exposure also reported by other authors (18,19,22,23,25). Fitzpatrick phototype II was significantly related to AC presence (OR 2.94); this is coherent with previous AC prevalence studies that found a significant correlation with light/fair skin or white/Caucasian race (18)(19)(20)(21)(22)(23)25).…”

“…The rest of the analysed variables were not significant. Sex distribution showed a high proportion of females in both the screening and the AC population (59.1% and 55.4%, respectively) and this could be related to the higher tendency of women to seek dermatological consultation compared with men (30); in contrast, other AC prevalence studies showed a clear superiority of men (15,16,18,19,23,25) and the reasons the authors gave for that finding were that women often use lipsticks providing a physical block against UV radiation, have a bigger tendency to use a sunscreen and are less frequently engaged in outdoor activities. Furthermore, an important percentage of the AC prevalence studies were performed in specific populations with professional activities that clearly have a male predominance (fishermen, sugar cane collectors, farmers, rural workers).…”

“…The prevalence of AC in our study was 31.3%. The AC prevalence data described in the literature comprise a wide range, between 0.9% and 43.24% (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25), and these differences could be related to the non-homogeneous clinical definition of AC and to the different inclusion criteria. Moreover, the majority of these studies were performed in selected populations, such as fishermen, sugar-cane collectors and rural workers from very specific geographical locations, lacking the advantages of a multicentre cross-sectional study.…”

“…There have been few epidemiological studies of AC compared with those related to AK; prevalence data of AC proceed from heterogeneous epidemiological studies performed in specific populations, mainly in South America (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25), thus the prevalence in Europe has not been established, since multicentre, well-designed prevalence studies have not been performed.…”

Oral erythroplakia—What is it?

“…In general population samples outside the hospital environment, the prevalence is found to be lower. Among 1241 individuals (47.1% women) in India, the prevalence of erythroplakia was 0.24% (Kumar et al., ), and a similar prevalence (0.3%) was found among 1385 rural Brazilian workers, of which 53.2% were females (Ferreira et al., ).…”
