Much of my research is on public health, health promotion and health inequalities. I want to increase our understanding of how factors in society, in social and physical environments, influence our health behaviours and explain socioeconomic differences in health behaviours. I have focusing on energy balance-related behaviours (EBRB) and on inequalities in health on children and youth. The socioecological framework has been used as reference model in studies. The studies are mainly quantitative.
