The Impact of Physical Activity on the Outcome of Surgery
Over the last decades different life style factors have been established as risk factors for various diseases. The obesity pandemic displays a good example of a disease where great effort is undertaken to characterize risk factors associated with obesity (1). Smoking is another life style risk factor established since several decades, and where primary prevention has been increasingly successful (2, 3). Cardiovascular epidemiologic research at the University of Gothenburg recognized PA as a factor of importance early on and thus included PA related questions in the work up of studies with large cohorts (4-6). A 4-level scale was introduced in the late 1960:s by Saltin and Grimby (7) and has been used extensively since then. With this background it is of interest to record physical activity one year and one month prior to certain types of elective surgery and to study the relationship of PA to surgical complications and recovery is of interest.
The aim of this study is to investigate whether a higher physical activity prior to a surgical procedure reduces hospital stay, sick leave and the complication rate.
A secondary aim is to investigate the effect of preoperative physical activity on the rate of resumption of QoL and normal physical function.

Time Perspective: Prospective
|Official Title:||The Impact of Physical Activity on the Outcome of Surgery|
- Length of sick-leave/time to work [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]for breast cancer and gallbladder surgery
- Length of hospital stay [ Time Frame: 6 weekw ] [ Designated as safety issue: No ]for colorectal surgery
- length of sick leave/time to work [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]for colon and rectal cancer: length of sick leave/time to work
- length of hospital stay [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]cholecystectomy and breast cancer: length of hospital stay
- Recovery [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]Recovery measured as resumption of Quality of Life and return to normal function after surgery according to the patient's self-reported assessment in the postoperative questionnaire and measured as return to pre-operative levels.
- Health economic analysis [ Time Frame: 12 months ] [ Designated as safety issue: No ]Health economic analysis of resource consumption
