Long work hours (≥60 hours / week) are associated with poor glycemic control in young Japanese men with type 2 diabetes , according to a study published in the January issue of the  Journal of Diabetes Investigation .

This hospital- and the clinic-based prospective study included 352 male and 126 female patients with diabetes aged 20-40 years . Data were obtained from June to July 2012 and June to July 2013.

Logistic regression analysis was used to estimate multivariate-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for suboptimal glycemic control (glycosylated hemoglobin level of ≥7%) obtained from June to July 2013.

Type 2 diabetes

Yasushi Azami, from Jouhoku Hospital in Kanazawa, Japan, and colleagues assessed associations between working conditions, eating habits, and glycemic control among Japanese workers with type 2 diabetes (352 men and 126 women aged 20 to 40 years).

The researchers found that suboptimal glycemic control in male workers was associated with a disease duration of ≥10 years (odds ratio [OR], 2.43), glycosylated  hemoglobin level  of ≥7% at baseline (OR, 8.50), skipping breakfast and having late evening meals (OR, 2.50).

And working ≥60 hours / week (OR, 2.92). In female workers, suboptimal glycemic control was associated with a glycosylated hemoglobin level of ≥7% at baseline (OR, 17.96), oral hyperglycemic agent therapy (OR, 12.49), and insulin therapy (OR, 11.60). "To maintain close to normal glucose levels, interventions to reduce unhealthy lifestyles and reduction in working hours are necessary," write the authors.

Working ≥60 h / week and habitual skipping breakfast concomitant with late evening meals might affect the ability of young male workers with type 2 diabetes to achieve and maintain glycemic control.
