The IMPACT research group – Marie Löf

The IMPACT research group focuses on prevention of overweight and obesity in pregnancy and childhood. We use mobile phone technology (mHealth) to measure diet and physical activity, and to deliver interventions promoting a healthy lifestyle in different populations, especially in maternity and child healthcare. Our research includes mHealth for self-management and treatment of disease e.g., gestational diabetes. We provide education in Nutrition and are part of the Centre for Nutrition, BioNut.
