N2 - It is estimated that 5% of women in the United States and 10% to 50% of women worldwide are physically inactive. Previous studies have demonstrated that recreational physical activity is associated with decreased risks of developing breast, colon, and endometrial cancers. The association between physical activity and epithelial ovarian cancer (EOC) is less clear. Despite extensive research, including several epidemiological studies and 2 systematic reviews, insufficient and inconsistent evidence is available to support an independent association between recreational physical activity and risk of EOC. This is largely due to use of common methodology in most studies that overlooks recreational physical inactivity as an independent risk factor for EOC.The aim of this study was to determine whether self-reported, chronic, recreational physical inactivity is an independent risk factor for increased risk of EOC. Individual-level data were obtained from a pooled analysis of 9 population-based case-control studies from the Ovarian Cancer Association Consortium. Seven of these studies were conducted in the United States and the remaining 2 in Europe. Women who reported no regular, weekly recreational physical activity were classified as inactive, according to the 2008 Physical Activity Guidelines for Americans. The association between physical inactivity exposure and EOC risk overall was assessed using multivariable logistic regression. Subgroup analysis was performed based upon EOC histotype, menopause status, race, and body mass index (BMI).The combined data set included 8309 EOC patients and 12,612 controls.Meta-analyses showed a significant positive association between inactivity and EOC risk; the odds ratio was 1.34, with a 95% confidence interval of 1.14 to 1.57. Similar positive associations were observed for each histotype.These data from a large pooled analysis show consistent evidence of a statistically significant positive association between self-reported, chronic recreational physical inactivity and all EOC histotypes The findings add to the growing body of evidence suggesting that inactivity is an independent risk factor for several types of cancer. If the apparent association between inactivity and EOC risk is confirmed, additional prospective epidemiological studies should be conducted to determine the amount of physical activity (dose response) required to reduce the risk of EOC.
