Work-related psychosocial stress and glycemic control among working adults with diabetes mellitus.

OBJECTIVE

To examine the association between glycosylated hemoglobin (HbA1c) and four subscales of work-related psychosocial stress at study baseline and over time.

MATERIALS AND METHODS

We used survey data from a major HMO located in the Southeastern part of the US on health and healthy behaviors linked with patients' clinical, pharmacy and laboratory records for the period between 2005 and 2009. Study participants (n=537) consisted of working adults aged 25-59 years, diagnosed with diabetes mellitus (DM) but without advanced micro or macrovascular complications at the time of the survey. We estimated the baseline (2005) association between HbA1c and work-related psychosocial stress and their interactions using linear regression analysis. Using individual growth model approach, we estimated the association between HbA1c over time and work-related psychosocial stress. Each of the models controlled for socio-demographic variables, diet and physical activity factor, laboratory factor, physical examinations variables and medication use in a hierarchical fashion.

RESULTS

After adjusting for all study covariates, we did not find a significant association between work-related psychosocial stress and glycemic control either at baseline or over time.

CONCLUSION

Among fairly healthy middle aged working adults with DM, work-related psychosocial stress was not directly associated with glycemic control.
