Resumo
Objetivo: Investigar a associação entre os níveis de atividade física ao longo da vida, nos domínios doméstico, ocupacional e recreativo, e o risco de desenvolvimento de câncer de mama em usuárias de um serviço público de saúde. Métodos: Estudo observacional, quantitativo, do tipo caso-controle, realizado no ambulatório de Mastologia do Hospital São Paulo, Universidade Federal de São Paulo, entre maio de 2016 e outubro de 2018. Participaram 241 mulheres, sendo 80 com histórico de câncer de mama e 161 com doenças mamárias benignas. A atividade física foi avaliada pelos questionários Lifetime Total Physical Activity Questionnaire e Baecke. As análises incluíram teste t, qui-quadrado e regressão logística múltipla ajustada por idade, etnia e histórico familiar. Resultados: Não houve associação significativa entre atividade física total ao longo da vida e risco de câncer de mama. Após estratificação por estado menopausal, maior atividade física ocupacional associou-se a menor chance de câncer de mama na pós-menopausa (p=0,03; OR=0,99; IC95%: 0,98–0,99). Conclusão: A atividade física ocupacional associou-se a menor chance de câncer de mama na pós-menopausa, porém os resultados devem ser interpretados com cautela.
