In search for explanatory pathways linking job stress to cardiovascular
disease, the relationship between job stress and diabetes, one of
the main coronary risk factors, was assessed in a cross-sectional
way in a large Belgian cohort.
Methods: 16,335 male and 5084 female workers, aged
35-59 years, and working in a wide range of different occupations,
volunteered to participate in the study. The participants completed
a questionnaire and underwent a clinical examination. Non-insulin
dependent type II diabetes was assessed through a question on existence
of hyperglycaemia and a question on medication use; job stress was
defined according to the Karasek Demand-Control model, by means of
the Job Content Questionnaire (JCQ). Logistic regression analyses
were performed for the scales on Psychological Job Demands (PJD),
Job Control (JC) and Social Support at Work (SSW) as well as for the
combined Demand-Control scale (Job Strain). Adjustments were made
for those covariates that were significantly related to diabetes prevalence,
insulin dependent diabetes cases were excluded from the analyses.
Results: Overall type II diabetes prevalence was
2.6% in males and 2.1 % in females.
Conclusions: Even if self-reported diabetes was used
in present analyses, taking into consideration the biological plausibility,
these results support the idea that there is an association between
job stress, defined as either a combination of high psychological
job demands and low job control as well as a lack of job control alone
and the prevalence of diabetes.
