Gestational Diabetes | Autonomic Nervous System and Exercise In Gestational Diabetes

Gestational Diabetes research study

What is the primary objective of this study?

The focus of this study is on individualized exercise prescription on primary prevention of cardiovascular diseases (CVD). Special attention is set on autonomic nervous system function and inflammation. This study will seek novel, cost-effective models of exercise prescription that will emphasize individuals own response on her health and which would be easily implemented to primary health care as primary prevention for CVD. According to power calculation,sixty women planning pregnancy with BMI equal or over 30 and/or history of GDM will be recruited and randomized to an individual exercise arm (n=20), a general exercise arm (n=20) and a control arm (n=20). General intervention group will receive general exercise and dietary counselling whereas a personal exercise and dietary programs will be planned for individualized exercise group. Those randomized to the control arm will receive no dietary and exercise information. Clinical exercise tests and autonomic nervous system tests will be performed in the beginning of the study and after 3 months intervention. Blood samples for markers of inflammation, glucose homeostasis and lipid status will be collected from prepregnancy period until 1 years after delivery.
