Brief Summary: Introduction Stress is part of the investigators daily life and means to cope with it allow adaptation and survival To this end physiological pathways are activated including neuroendocrine cardiovascular and metabolic responses In short term the majority of consequences are beneficial in the long run however chronic psychosocial stress may constitute an increased risk for coronary heart disease type 2 diabetes and disability

Acute mental stress induces an exaggerated release of stress hormones eg catecholamine and cortisol which are thought not only to increase heart rate HR and blood pressure BP but also to increase blood glucose levels In clinical practice patients and health care providers are often confronted with questions concerning psychological stress as a possible reason for glucose fluctuations Whether stress itself or poor treatment adherence is responsible for the altered glucose control remains often controversial Differences in the inter- and intraindividual response to stress have been suggested but only a few small studies have addressed the effect of acute psychological stress on glucose control in patients with diabetes Patients with type 2 diabetes may overestimate the effect of acute psychological stress on glucose control but further studies are clearly needed to definitely exclude or confirm a relevant effect of stress on the glucose control in diabetic patients For example effects of longer lasting or repetitive events of psychological stress on glucose concentrations still remain elusive The aim of the present study was therefore to investigate the effect of prolonged psychological stress by means of repetitive safe driving training courses on glucose control in patients with diabetes

Patients and Methods Forty patients with type 1 or insulin-treated type 2 diabetes attending the outpatient-clinic of the Kantonsspital Frauenfeld or University Hospital of Zurich for regular visits are invited to participate Included are patients on any oral glucose-lowering treatment and at least one daily injection of insulin a valid driver license and written informed consent given Exclusion criteria are diabetes duration 2 years pregnancy unstable coronary artery disease limited visual acuity or unstable proliferative diabetic retinopathy uncontrolled hypertension BP 16095mmHg and pituitary or adrenal disease The Ethics committee of the Kanton Thurgau approved the protocol and the study conform to the principles outlined in the Declaration of Helsinki

Study protocol Each patient completes a control and a stress testing day which takes place consecutively in a randomized order Randomization is performed by an uninvolved third person The study is carried out at the driving training area of the Touring Club Switzerland at Hinwil Patients are advised to have lunch before 1200 am and to abstain from food thenceforth Drinking mineral water remains allowed during the entire study days and the patients have to take their basal insulin and other medication as usual Patients are advised to arrive at the driving training area between 230 and 300 pm At arrival a capillary glucose measurement is carried out and glucose concentrations 10mmoll are corrected with short-acting insulin analogues glucose target 6 - 8mmoll Subsequently no additional adjustment with insulin is allowed during the study Glucose concentrations 4mmoll are always corrected with administration of 10g carbohydrate DextroEnergy or orange juice On both study days patients ingest a standard meal at 445 pm ie 15min before the driving training Immediately after the meal short-acting insulin is injected in knowledge of the carbohydrate content same dose on both days or oral antidiabetics are ingested as usual Measurements of capillary and plasma glucose concentration blood pressure heart rate stress perception and salivary cortisol concentration are carried out in regular intervals between 4 and 9 pm on both study days

On the control day patients are placed in a quiet room and are permitted to read They also have the possibility to leave the room and stay on a balcony

On the stress testing day patients complete a driving training with their car between 5 and 7 pm The driving training consists of 3 consecutive exercises first a slalom track on dry and wet asphalt secondly a full braking exercise with water obstacles Thirdly the car is hurled around by a mechanical plate and the patients has to regain control over it
