| Résumé : | [BDSP. Notice produite par INIST n1oZBR0x. Diffusion soumise à autorisation]. To evaluate whether recreational physical activity is associated with breast cancer among young women, the authors analyzed data from a population-based case-control study. Cases (n=1,668) were women under age 45 years who had been newly diagnosed with breast cancer between 1990 and 1992 in Atlanta, Georgia, central New Jersey, or Seattle, Washington. Controls (n=1,505) were frequency-matched to cases by 5-year age group and geographic area of residence. Breast cancer was not associated with recreational activity in any of the three time periods assessed (highest quartile of activity vs. lowest : age-and center-adjusted odds ratio (OR)=0.94 (95% confidence interval (Cl) 0.77-1.15) at ages 12-13 years, OR=1.08 (95% Cl 0.88-1.32) at age 20 years, and OR=1.18 (95% Cl 0.97-1.44) during the past year), with the average of the three time periods (OR=1.02,95% Cl 0.84-1.25), or with daily climbing of at least two flights of stairs (without stopping) during the past year (daily climbing vs. never climbing : OR=1.03,95% Cl 0.86-1.23). Estimates were not modified or confounded by body mass index, menopausal status, or caloric intake during the past year. These results do not support a protective role for physical activity in the risk of breast cancer among young women. |
