Gender differences in occupational exposure to carcinogens among Italian workers

Abstract

BackgroundMany carcinogenic chemicals are still used or produced in several economic sectors. The aim of this study is to investigate differences in occupational exposure patterns to carcinogens by gender in Italy.MethodsInformation about the most common carcinogens recorded in the Italian occupational exposures database (SIREP) for the period 1996–2015 was retrieved. Descriptive statistics were calculated for exposure-related variables (carcinogenic agent, occupational group, economic activity sector, and workforce size). The chi-square(χ2) test was used to verify differences between genders, and logistic regression analysis was performed to evaluate the association between gender and risk of having higher exposure levels, after adjusting for age. Concurrent exposures to multiple carcinogens were investigated using the two-step cluster analysis.ResultsA total of 166,617 exposure measurements were selected for 40 different carcinogens. Exposed workers were only in a small proportion women (9%), and mostly aged 20–44 years (70%) in both genders. Women were more likely to be exposed than men to higher levels for several carcinogens even after correction for age at exposure, and the exposure level was significantly (p < 0.01) associated with occupation, economic sector and workforce size. The five main clusters of co-exposures identified in the entire dataset showed a differential distribution across economic sectors between genders.ConclusionsThe exposures to occupational carcinogens have distinguishing characteristics in women, that are explained in part by work and job segregation. Because of the presence of high-exposed groups of female workers in many industrial sectors, further research and prevention efforts are recommended.

Gender differences in experience and reporting of acute symptoms among cleaning staff

“…Potential differences in occupational exposures between women and men may explain some of the differences in symptom experience by gender. Occupational segregation or gender differences in employment conditions, job titles, or work assignments have been documented in occupational health literature 27,40,41 . Indeed, our study observed some differences in work activities between female and male cleaning workers.…”

Excess Risk of Lung Cancer Among Agriculture and Construction Workers in Indonesia

“…"Model 1" analysis discovered the ORs among all IndSIC sections using "housewife" as "Reference 1" and Section S (Other services as member of organization, repair of household) as "Reference 2". Housewives, the "Reference 1", were considered to have the most similar tasks in all settings, less probability of contact to workplace exposures, the majority of them being non-smokers, and them being at a lower risk of lung cancer compared to other occupations [24][25][26][27][28]. The limitation of this reference group is that they were not part of IndSIC and that they were all females.…”

Metabolism and genotoxicity of polycyclic aromatic hydrocarbons in human skin explants: mixture effects and modulation by sunlight

“…Some of them are associated with increased cancer risk upon exposure to PAH and other xenobiotics (Gajecka et al 2005;Olshan et al 2000). In addition, investigation of the gender effect is important since it is known most of the jobs associated with high PAH exposure are mostly made by men (Scarselli et al 2018).
