The percentages were calculated relatively to the number of participants for each social position (high=37 939; middle=62 227; low=30 031) or work environment (good=40 740; average=47 174; bad=42 283).
Models 1 included either social position, work environment or unemployment duration and were adjusted for sex, age and parental history of cancer.
Models 2 included social position, work environment and unemployment duration and were adjusted for sex, age and parental history of cancer.
Models 3 included social position, work environment and unemployment duration and were adjusted for sex, age, parental history of cancer, lifetime non-moderate alcohol consumption, smoking, body mass index and sleep disorders.
