No
Confounders considered
Other breast cancer risk factors, such as family history, age at first birth, and hormone replacement therapy use, that were taken into account in the study.
BMI, race, menopausal status, alcohol consumption, family history of breast cancer
Genetic characterization included
If the study analyzed relationships between environmental factors and inherited genetic variations, this field will be marked “Yes.” “No”, if not.
No
Description of major analysis
Cox proportional hazard model adjusted for cohort membership. Additional adjustment for maternal proteinuria, birth order, own parity, and age at menarche did not have a marked effect on birth weight estimate. Additional adjustment for age at menarche inc
Strength of associations reported
Birthweight: 1.57 (0.67 - 3.64); birth length: 2.21 (0.88 - 5.53) (adjusted for age at menarche)
Results Comments
High weight or length at birth was associated with a non-significant increase in risk for cancer in adulthood
