  • * Models adjusted for age (continuous), total energy (continuous), family history of breast cancer (yes, no), personal history of fibroadenoma (yes, no), age at menarche (≤12, 13, 14, 15, 16, ≥17 y), live births and age at first live birth (<20, 20-24, 25-29, 30-34, ≥35, nulliparous), menopausal status and age at menopause (premenopausal, age at menopause <45, 45-49, 50-54, ≥55 y), regular physical activity during last 10 y (yes, no), waist-hip ratio (WHR, continuous), BMI (continuous), and level of education (no formal education, elementary, middle and high school, college and higher).

  • P value for trend was obtained for each pattern by including in the model a variable representing the median value for each quartile.
