The AG 4 is made up of a multi-disciplinary research team, primarily from the fields of public health, psychology and sports sciences. In research, as in teaching, our focus is on how best to promote health and prevent illness. We consider the social and physical environment to be just as important as individual factors (such as personal motivation and attitude). Our research priorities lie in children and youth health, women-focused and gender-equitable health research, and the area of evaluation and quality development.
