Abstract

Abstract

Objective To assess the association between physical activity and risk of breast cancer. Methods A hospital-based case-control study was conducted in two affiliated hospitals of a university between April 2012 and December 2014. Face to face interviews were completed among 549 breast cancer cases and 549 controls. Physical activity and potential risk factors of breast cancer were collected by using a standard questionnaire. Multivariate unconditional Logistic regression model was used to estimate the association between physical activity and breast cancer risk. Results A lower risk for breast cancer was observed for highest levels of non-occupational physical activity (OR=0.69,95% CI:0.48-1.00), for recreational activity (OR=0.61, 95% CI:0.43-0.87), as well as for standing occupational activity (OR=0.67, 95% CI:0.47-0.97), while household activity showed null result. Non-occupational physical activity showed reverse association with ER+/PR+ breast cancer risk. Conclusions Non-occupational physical activity, recreational activity and standing occupational activity are inversely associated with breast cancer risk.
