↵2-150 Age adjusted mean was estimated with analysis of covariance (ANCOVA) controlling for age as a continuous variable. For multivariate adjusted average, age, body mass index, smoking, alcohol consumption, daily energy intake, leisure time physical exercise, and family history of diabetes were controlled for.
↵2-151 The subjects were classified into four quartiles on the basis of each variable.
↵2-152 Job strain was calculated as a ratio of job demands to job control (job demands score divided by half the job control score).21
