Background The process of immigration is associated with poor mental and physical health. While the workplace represents an important context of social integration, previous studies evaluating the effect of discrimination experienced in the workplace found worse mental health status among immigrants. The aim of this study was to investigate whether self-perceived workplace discrimination has any role in the mental health status of immigrants living and working in Italy, evaluating the contribution of other personal experiences, such as loneliness and life satisfaction. Methods A cross-sectional study was conducted on a sample of 12,408 immigrants (aged 15–64) living and working in Italy. Data were derived from the first national survey on immigrants carried out by the Italian National Institute of Statistics (Istat). Mental health status was measured through the Mental Component Summary (MCS) of the SF-12 questionnaire. A linear multivariate linear regression was carried out to evaluate the association between mental health status, self-perceived workplace discrimination, and sociodemographic factors; path analysis was used to quantify the mediation effect of self-perceived loneliness, level of life satisfaction, and the Physical Component Summary (PCS). Results Mental health status was inversely associated (p < 0.001) with self-perceived workplace discrimination (β:-1.737), self-perceived loneliness (β:-2.653), and physical health status (β:-0.089); it was directly associated with level of life satisfaction (β:1.122). As confirmed by the path analysis, the effect of self-perceived workplace discrimination on MCS was mediated by the other factors considered: self-perceived loneliness (11.9%), level of life satisfaction (20.7%), and physical health status (3.9%). Conclusions Our study suggests that self-perceived workplace discrimination is associated with worse mental health status in immigrant workers through personal experiences in the workplace and explains the effect of the exposure to workplace discrimination on immigrants’ psychological well-being. Our findings suggest that an overall public health response is needed to facilitate the social integration of immigrants and their access to health services, particularly those services that address mental health issues.

Background: Immigration process is associated with poor mental and physical health. The workplace represents an important context of social integration, and previous studies, that evaluated the effect of discrimination experienced at workplace, found worse mental health status among immigrants. The aim of this study investigated the association between self-perceived workplace discrimination and other personal experiences, like self-perceived loneliness, level of life satisfaction, and physical health and mental well-being among immigrants in Italy. Methods: A cross-sectional study was conducted on a sample of 12,408 immigrants (aged 15-64) living and working in Italy. Data derived from the first national survey on immigrants carried out by the Italian National Institute of Statistics (Istat). Mental health status was measured through the mental component summary (MCS) of the SF-12 questionnaire. A linear multivariate regression was carried out to evaluate the association between mental health status, self-perceived workplace discrimination, and sociodemographic factors; a structural equation model was used to test hypothesized relationships shown in a conceptual path analysis model. Results: Worse mental health status was independently (p<0.001) associated with self-perceived workplace discrimination (β:-1.873), self-perceived loneliness (β:-3.021), level of life satisfaction (β:-2.775), and physical health status (β:-0.088). As confirmed by structural equation model, the selfperceived workplace discrimination effect on MCS was mediated by the other factors considered: selfperceived loneliness (13.6%), level of life satisfaction (13.6%), and physical health status (3.9%).Conclusions: Our study suggest that self-perceived workplace discrimination is associated with worse mental health status in immigrant workers. These results support the hypothesis that self-perceived workplace discrimination may affect mental health status through personal experiences in the workplace and explain the effect of the exposure to workplace discrimination on immigrants' psychological well-being. Our findings suggest that an overall public health response to facilitate the social integration of immigrants and their access to health services, in particular those dedicated to addressing mental health issues.
