Association Between Physical Activity and Lower Risk of Lung Cancer: A Meta-Analysis of Cohort Studies.

ABSTRACT: Background: Epidemiological evidences regarding the association between physical activity and the risk of lung cancer are still controversial. Objectives: We aimed to investigate the relationship between physical activity and risk of lung cancer in men and women, as well as other high-risk populations such as cigarette smokers. Methods: We conducted a meta-analysis of cohort studies to evaluate the association between physical activity and risk of lung cancer. Relevant studies were identified by searching PubMed and Web of Knowledge through August 2018. Study-specific relative risk (RR) with 95% confidence interval (CI) were pooled using random effect model when significant heterogeneity was detected. Results:Twenty cohort studies with a total of 2,965,811 participants and 31,807 lung canc
