Atividade Física e Câncer de Pulmão: um estudo caso controle

Abstract

The aim of this study was to investigate the association between physical activity (PA) engagement throughout life and the incidence of lung cancer (CA) in southern Brazil. A case control study was carried out. Both cases and controls responded to a questionnaire containing questions about sociodemographics , gender, age and skin color, anthropometric information, marital status, education, smoking and family history of CA. Physical activity was measured using the Lifetime Physical Activity Questionnaire. We studied a total of 249 individuals (81 cases and 168 controls). In the crude analysis, active commuting increased the odds for CA (p=0.01) and sports activities resulted in non-significant protection (p=0.05). In the adjusted analysis, the occupational PA (p=0,009) and lifetime PA (p=0.02) were associated to lower odds of CA, while active commuting (p=0.03) and household activities (p=0.01) were associated with increased odds of CA. For this reason, it s extremely important to encourage the practice of PA since childhood, because considering the consistent evidence on the importance of PA in the prevention of many diseases in adulthood, including CA, its encouragement at early ages may represent a strategy to control physical inactivity worldwide and hence reduce the epidemic of chronic diseases
