abstract = "PURPOSE: Physical activity is a modifiable lifestyle risk factor in prevention of breast cancer. Mammographic density (MD) is a strong risk factor for breast cancer. We investigate the association of regular physical activity with MD.METHODS: For 5,703 women who participated in the Danish Diet, Cancer and Health cohort (1993-1997) and attended mammographic screening in Copenhagen (1993-2001), MD was assessed at the first screening after cohort entry. MD was defined as a binary measure equivalent to Breast Imaging Report and Data System (BI-RADS) to either mixed/dense or fatty. Participation and duration in physical activities (hours/week) and confounders were assessed by questionnaire at cohort baseline. Logistic regression was used to estimate associations [odds ratios (OR), 95{\%} confidence intervals (CI)] between physical activities and MD.RESULTS: 56.3{\%} of women had mixed/dense MD and 47.6{\%} participated in sports. We found a significant positive association between participation in sports (OR 1.15; 95{\%} CI 1.03-1.28) and do-it-yourself work (1.17; 1.05-1.31) and odds of having mixed/dense MD, which attenuated (1.08; 0.96-1.22 and 1.11; 0.98-1.25, respectively) in a fully adjusted model. No associations were found for time spent on physical activities or total metabolic equivalent of task scores with MD, in fully adjusted models. There was no effect modification of association between any physical activities and MD by obesity (BMI ≥ 30 kg/m2) and menopause status.CONCLUSIONS: Physical activity is not a determinant of MD.",
