Cluster 1: younger workers who retired between 2001 and 2003; Cluster 2: older workers with bad working conditions who retired between 1991 and 1998; Cluster 3: younger retired workers with high social position; Cluster 4: older retired workers with high social position; Cluster 5: older retired workers with middle social position; Cluster 6: younger retired workers with middle social position; Cluster 7: retired workers with low social position; Cluster 8: younger workers who retired between 1999 and 2000
αHazard ratios (HR) and their standard errors (SE) were estimated using Cox proportional hazard regression models. Proportional hazard assumption χ2=6.59 (df=7; p=0.47)
βHazard ratios (HR) and their standard errors (SE) were estimated using Cox proportional hazard regression models. Proportional hazard assumption χ2=13.5 (df=7; p=0.06)
ap values are significant (p<0.01)
