2 Main topics of research Risk factors and prevention of musculoskeletal health, work disability, sickness absence, cardiovascular disease and premature mortality. Particular focus on the importance of physical work demands and individual physical resources for the abovementioned factors by use of different methodological designs (e.g. epidemiological and intervention studies) and development of methods for objective long-term field measures of physical work demands and physiological response.
