Work Environment-related Stress Factors are Correlated with Diabetes Development in Workers with Impaired Glucose Tolerance: A 5-year Follow-up Study Using the Brief Job Stress Questionnaire (BJSQ).

Several previous studies have investigated the effects of occupational stress on the onset of diabetes mellitus (DM), but there are few studies of occupational stress and DM using the Brief Job Stress Questionnaire (BJSQ), a standard stress check method in Japan. This study aimed to determine the relationship between occupational stress factors and the onset of DM using the BJSQ. We examined 6,620 male company workers aged 40 years and above in 2013, using the BJSQ. Overall, 2,604 subjects with impaired glucose tolerance who were free of mental disorders and DM were followed-up for 5 years and re-examined in 2017. A retrospective data analysis was conducted in 2019. We documented 241 new cases of DM in 2017 (diabetes group). Compared with the non-diabetes group, the subjects in the diabetes group had significantly decreased "skill utilization". A binomial logistic regression analysis (generalized linear model) revealed that "skill utilization" was associated with the risk of DM development in 2017 (odds ratio, 1.632; 95% confidence interval, 1.061-2.510). Our results showed that low skill utilization might increase the risk of diabetes development in Japanese male workers.
