Job strain can significantly increase the risk of developing diabetes. This conclusion was based on prospective data from a population-based study conducted by scientists at the Helmholtz Zentrum München. The findings have been published in the scientific journal Psychosomatic Medicine.
Workplace stress can have a range of adverse effects on health with an increased risk of cardio-vascular diseases in the first line. However, to date, convincing evidence for a strong association between work stress and incident Type 2 diabetes mellitus is missing.
Risk of diabetes about 45 percent higher
As the team of scientists headed by Dr. Cornelia Huth and Prof. Karl-Heinz Ladwig has now discovered that individuals who are under a high level of pressure at work and at the same time perceive little control over the activities they perform face an about 45 percent higher risk of developing type 2 diabetes than those who are subjected to less stress at their workplace.
The scientists from the Institute of Epidemiology II (EPI II) at the Helmholtz Zentrum München (HMGU) in collaboration with Prof. Johannes Kruse from the University Hospital of Giessen and Marburg examined data prospectively collected from more than 5,300 employed individuals aged between 29 and 66 who took part in the population-based MONICA/KORA* cohort study. At the beginning of the study, none of the participants had diabetes, while in the post-observation period, which covered an average of 13 years, almost 300 of them were diagnosed with type 2 diabetes. The increase in risk in work-related stress was identified independently of classic risk factors such as obesity, age or gender.
Holistic prevention is important - also at the workplace“
type 2 diabetes" align="right" /> According to our data, roughly one in five people in employment is affected by high levels of mental stress at work. By that, scientists do not mean ‘normal job stress’ but rather the situation in which the individuals concerned rate the demands made upon them as very high, and at the same time they have little scope for maneuver or for decision making. We covered both these aspects in great detail in our surveys,” explains Prof. Ladwig, who led the study. “In view of the huge health implications of stress-related disorders, preventive measures to prevent common diseases such as diabetes should therefore also begin at this point,” he added.
Environmental and lifestyle factors play a key role in the development of widespread diseases in Germany such as diabetes mellitus. The aim of the Helmholtz Zentrum München, a partner of the German Center for Diabetes Research (DZD), is to develop new approaches to the diagnosis, treatment and prevention of the most common diseases.
*For more than 20 years, the research platform Cooperative Health Research in the Augsburg Region (KORA) has been collecting and analyzing data on the health of thousands of people living in the Augsburg region. The objective is to elucidate the effects of environmental factors, behavior and genes. KORA focuses on the development and course of chronic diseases, in particular myocardial infarction and diabetes mellitus. Risk factors are analyzed with regard to individual health behavior (e.g. smoking, diet, exercise), environmental factors (e.g. air pollution, noise) and genetics. From the perspective of health care research, questions regarding the utilization of health care resources and the cost of health care are also studied.
