Abstract

Background: Increasing numbers of US workers are diabetic. We assessed the relationship between glycemic control and work hours and type of occupation among employed US adults with type 2 diabetes.

Methods: Data were obtained from the 1999-2004 National Health and Nutrition Examination Survey (NHANES). A representative sample of employed US adults ≥20 years with self-reported type 2 diabetes (n = 369) was used. Two dichotomous glycemic control indicators, based on various HbA1c level cut-points, were used as dependent variables in weighted logistic regression analyses with adjustment for confounders.

Results: Adults working over 40 hr/week were more likely to have suboptimal glycemic control (HbA1c ≥ 7%) compared to those working 20 hr or less (odds ratio = 5.09; 95% confidence interval: [1.38-18.76]).

Conclusions: Work-related factors, such as number of hours worked, may affect the ability of adults with type 2 diabetes to reach and maintain glycemic control goals. These factors should be considered in the development of workplace policies and accommodations for the increasing number of workers with type 2 diabetes.
