*
Adjusted for age, sex and cohort.
†
Defined as having a job with high demands (a job-demand mean score above the study-specific median) and low control (a job-control mean score below the study-specific median); “no job strain” was denoted by all other combinations of demands and control.
‡
Smoking, heavy drinking, physical inactivity and obesity. 0 lifestyle risk factors = healthy lifestyle, 1 risk factor = moderately unhealthy lifestyle, 2–4 risk factors = unhealthy lifestyle.
