^*Adjusted for age, (Age non significant, p=0.07).

^‡Defined as consuming >4 alcoholic drinks in any one drinking occasion from 2011–2013, and >=4 drinks in any one drinking occasion from late 2013 onwards.

^§For this analysis, race was dichotomized. Black/African American women were compared to a single reference category including all other races. This was due to small sample size in some race categories.

^†Pill, patch, ring, depot medroxyprogesterone acetate and emergency contraceptive pill were included as hormonal contraception.
