A blood sample was taken from the participants and HbA1c (%) was measured. Job strain and social support at the workplace were assessed with the job content questionnaire (JCQ). After excluding those who had a history of diabetes mellitus or other chronic diseases, data from 268 male day workers were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Age adjusted average concentrations of HbA1c were significantly higher in the highest quartile group of job strain or the lowest quartile group of social support at the workplace (p&lt;0.05). Multiple linear regression analysis indicated that job strain was significantly and positively related to HbA1c (p&lt;0.05), whereas social support at the workplace was significantly and negatively related to HbA1c (p&lt;0.05), both after controlling for other covariates.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>Greater job strain and lower social support at the workplace may be associated with increased concentrations of HbA1c.
