Long work hours linked to diabetes
Researchers pooled observational data from Australia, the US, Japan and Europe in a bid to ascertain diabetes risk from long working hours.
They found risk was elevated by 33% in manual workers and others in low status jobs, independent of other risk factors including obesity, age, physical activity and shift work.
In an editorial, experts said the finding suggested the possible role of sleep as a mediator. Inadequate quantity and quality of sleep were strongly predictive of type 2 diabetes, they said.
Work factors affecting health behaviour and stress might need to be a focus for diabetes prevention,
