Clinical Studies (D)
Personalized preventive and therapeutic measures, i.e. the right treatment for the right patient group at the right time, are the objective of the clinical multicenter studies of the DZD. In addition, they elucidate healthcare economic aspects. A central unit for coordinating the clinical studies at the DZD office ensures a standardized and high-quality implementation.
The DZD is currently working on various studies on diabetes prevention (PLIS), on diabetes sequelae (DDS) as well as on gestational diabetes (PREG).
Test Triangle Study
The "Test Triangle" study is aimed at women who have been diagnosed with gestational diabetes during a recent pregnancy. This metabolic disorder is associated with an increased risk of developing type 2 diabetes later on. However, the right lifestyle can significantly reduce this risk. Unfortunately, young mothers have little time for their own health. For this reason, the "Triangle" smartphone app was specifically developed for this group. The app provides support to help lead a healthy lifestyle in the areas of exercise, nutrition and stress reduction. Users of the app are mentored by a qualified online coach who takes their individual needs into account and who adapts the content of the app accordingly. With the help of the app, more healthy habits can be incorporated into the everyday life of the participants step-by-step over a period of 6 months.
Recruitment for this study has been completed.
Prediabetes Lifestyle Intervention Study (PLIS)
A conventional lifestyle intervention to prevent type 2 diabetes is not sufficient for all people with prediabetes. Only an individualized prevention strategy can be effective here. In the multicenter Prediabetes Lifestyle Intervention Study (PLIS), the DZD aims to develop such personalized preventive measures. After extensive phenotyping, the PLIS study participants undergo different lifestyle programs with nutritional counseling and supervised physical activity. The aim of the PLIS study is to find people who, despite increased efforts in everyday life, have an increased risk for type 2 diabetes and to offer them intensified lifestyle interventions supervised by a professional staff, so that these people, too, can benefit from a lifestyle modification. The study is being conducted at eight centers within the framework of the German Center for Diabetes Research (DZD). Here recruitment for the study has been concluded.
