This study aimed to explore the association between unemployment and mortality, considering potential confounders. Results showed a significant association between unemployment and higher mortality rates among men, with leading causes being neoplasms, cardiovascular diseases, and suicides. However, the lack of economic resources did not modify this association. Unemployment was not significantly associated with mortality among women.
Background Aim of this study was to examine the association between unemployment and mortality, taking into account potential confounders of this association. A secondary objective was to assess whether the association between unemployment and mortality was modified by lack of household economic resources. Methods Prospective cohort composed of a representative sample of Italian subjects 30-55 years who participated in the Italian National Health Survey 1999-2000, followed up for mortality up to 2012 (15 656 men and 11 463 women). Data were analyzed using Cox regression models, stratified by gender and adjusted for health status, behavioral risk factors, socioeconomic position and position in the household. The modifying effect of the lack of economic resources was assessed by testing its interaction with unemployment on mortality. Results Among women, unemployment was not associated with mortality, whereas among men, higher mortality was found from all causes (HR = 1.82), which was not modified by lack of economic resources, and from neoplasms (HR = 1.59), cardiovascular diseases (HR = 2.58) and suicides (HR = 5.01). Conclusions Results for men were robust to the adjustment for main potential confounders, suggesting a causal relationship between unemployment and mortality. The lack of effect modification by economic resources supports the relevance of the loss of non-material benefits of work on mortality.
