AA: African American.
Age was not reported by five participants. Race was not reported by 129 participants. Gender was not reported by 16 participants.
a
Difference in the percent correct response between Q9 and Q10 is significant (90.9 + 1.5 (Q9) versus 39.2 + 2.5 (Q10), p = .048, (paired t-test).
b
Q3 (all ages together) indicates that maternal diet is deemed to be unimportant in male offspring’s risk for breast cancer. There was no difference in this perception when analysed by gender.
