^aModel VI adjusted for age, job control, reward and social support (Table 3 and 4)
^bContribution calculated with this formula, (MD_basic – MD_adjusted)/(MD_basic), where MD_basic = Mean differences for age-adjusted models and MD_adjusted = Mean differences for models adjusted for work variables at each steps for the 0–39 999$ per year category for household income. Jackknife method was used to calculate 95% IC of the contributions
^cJob contractual instability, psychological harassment, flexible schedule, paid leaves for sickness, emotionally demanding work, strain with public and possibility to do a work of quality
^dNumber of working hours, work schedule, noise exposure, solvent exposure and physical work constraints
