This thesis examines how working conditions are associated with gender health disparities in Norway's gender-segregated labor market. Based on the work environment hypothesis, the research question is: How are mechanical and psychosocial working conditions associated with health-related outcomes, encompassing both health status and labor market attachment, among men and women in the Norwegian labor market?
Using Norwegian survey and register data, this thesis developed a gender-specific occupational Job Strain Index (Study I) and examined associations between working conditions and health-related outcomes among health-challenged populations: individuals with prior specialized healthcare contact (Study II) and cancer survivors (Study III).
Findings provided partial support for the work environment hypothesis while revealing complexities. Gender-specific, exposure-specific, and context-dependent patterns suggested that working conditions alone may not fully account for gender health disparities. Results point toward gender-responsive policies addressing distinct occupational health challenges and highlight the need to integrate the work environment hypothesis with other explanatory mechanisms.
