Data collected from more than 5,300 employed Germans aged 29-66 has revealed that, over 13 years, 291 developed type 2 diabetes. Those who were under a high level of pressure at work and also perceived themselves as having little control over their activities had about a 45% higher risk of developing type 2 diabetes than those subjected to less workplace stress.
