Abstract

Objective: This article describes the development process and summarizes the resultsof the Brazilian physical activity recommendations for cancer prevention and control,which was prepared to support health-care professionals.

Material and Methods: These recommendations were elaborated considering: (i) the effect of physical activity on cancer prevention in the general healthy population; and (ii) on all-cause and cancer-specific mortality in cancer survivors. The process of preparing the recommendations was systematized,transparent and reproducible, following the recommendations of the appraisal of guidelines for research and evaluation (AGREE-II). We appraised the certainty of evidence for breast,prostate, colorectal and lung cancers, which are among the most frequent in Brazil, using thegrading of recommendations, assessment, development and evaluations (GRADE) approach.

Results: Regarding the risk of cancer, we found high certainty of evidence supporting the association between moderate-to-vigorous physical activity and lower risk of breast and colon cancer, moderate certainty of evidence for lung cancer and low certainty of evidence for prostate and rectal cancer. We found moderate certainty of evidence supporting the association between moderate-to-vigorous physical activity and reduction of all-cause and cancer-specific mortality from breast, colon and rectal cancer, and cancer-specific mortality from prostate cancer, when physical activity was performed after the disease diagnosis.We found low certainty of evidence for the association between physical activity and lung cancer mortality. Based on our findings, physical activity recommendations were proposed,including a step-by-step guide to support health-care professionals when recommending physical activity for all adults (including elderly people), with or without a diagnosis of cancer.

Conclusion: Our recommendations may be useful to support health-care professionals counselling for physical activity, which contribute to reductions in physical inactivity in the general population and in the growing population of cancer survivors
