[Evidence-based Practice Session Presentation] Background: Several risk factors for breast cancer are well established, however the role of stress as one of these factors requires proof. Objective: Verify the association of life events which produce stress with the primary incidence of breast cancer among women. Method: Systematic review in the data bases MEDLINE/Pubmed, LILACS and Cochrane Library, in the period between 2006 and 2007. The selection of studies included 621 papers. The methodological quality was evaluated by and Black's criteria (1), while the level of evidence by Melnyk and Fineout-Oveholt's classification(2). The meta-analysis was carried out by the program Data Analysis and Statistical Software-Stata, version 9.0. Results: The meta-analysis consisted of six case-control studies and two of cohort. The scores of methodological quality varied between 14 and 20, all of them with evidence level IV. No association was found for stressing events, widowhood and divorce. However, the results suggest that there may be an association for stress degree/intensity. The RR regarding widowhood was 1,04 (p= 0,800); regarding divorce 1,03 (p=0,850), and regarding degree, intensity/frequency of stress 1,73 (p=0,059). Conclusion: There was no association of stressing life events with breast cancer. The small number of studies included, what reduced the statistical power, does not permit us to eliminate the possibility of association of stress degree/intensity and breast cancer.
