  • *Model 1: ORs were estimated by logistic regression conditioned on age (±3 years), city district of residence and health insurance institution and adjusted for education, (≤primary/secondary/>secondary), moderate intensity physical activity (continuous), number of full-term pregnancies (continuous), age at first full-term pregnancy (nulliparous/<20; 20–25; ≥25), breast feeding ever (yes/no), BMI (continuous) and total energy intake (continuous).

  • †Model 2: Additionally adjusted for energy intake from the other NOVA groups (NOVA 1, NOVA 2, NOVA 3 added simultaneously in the model).

  • ‡Cut-off points for tertiles are respectively: Tertile 1=≤495.5; tertile 2=495.5–896.6; tertile 3=>896.6 kcal/day.

  • BMI, body mass index; ER, oestrogen receptor .
