Physical activity and short-term (0–11 years) risk of breast cancer. Age- and multivariable-adjusted hazard ratios (HR) with 95% CI for a high versus low level of physical activity among all women, and by menopausal status or body composition. Women and breast cancer events shown represent the numbers available in the multivariable model. The forest plot illustrates multivariable-adjusted HR with 95% CI. ^a Model adjusted for age at baseline. ^b Multivariable model adjusted for age at baseline, age at menarche, parity, age at first childbirth, oral contraceptive use, current hormone replacement therapy use, socioeconomic index, and alcohol consumption. Models for all women or stratified by body composition (waist circumference, BMI, or body fat percentage) were additionally adjusted for age at menopause.
