Work related and non-work related stress in relation to low leisure time physical activity in a Swedish population.

P hysical activity is regarded as an important component of a healthy lifestyle. Several social and environmental factors have systematically emerged as barriers to low leisure time physical activity (LTPA), for example, lack of money, low social support due to lack of supportive family or friends, and living in high crime rate areas. Low LTPA has been found to be strongly associated with low socioeconomic status groups where psychosocial stressors have been suggested to play a mediating part. 2 The overall aim of this study was to investigate the association between work and non-work related stressors, respectively, in relation to low LTPA in a general population sample. Our main hypothesis was that psychosocial stressors would act as barriers to physical activity thus generating sedentary behaviour as measured by LTPA.
