Glucose intolerance and General Health Questionnaire 12-item version scores of male two-shift workers stratified by precariousness of work.
OBJECTIVE
This study examined the relationship between precariousness of work, glucose intolerance and psychological wellbeing for male workers, stratified by age.


METHODS
I recruited 2542 manufacturing two-shift workers, aged from 35 to 54 years. Glucose intolerance was defined as fasting plasma glucose of ≥100mg/dL or current medication of diabetes mellitus. The rating scale of General Health Questionnaire 12-item version (GHQ-12) was used for evaluating psychological well-being.


RESULTS
There was a significant increase in the prevalence of glucose intolerance by aging in permanent workers. In addition, the prevalence of glucose intolerance except 30s and the prevalence of positive GHQ-12 scores except 50s of permanent workers were both significantly higher than that of temporary workers in each age class.


CONCLUSIONS
Temporary workers in this study sign contracts for 3 years, and heather worker's effect, compared with permanent workers, would be reflected in this study.
