A quarter (24 %; 1,921/7,965) of mothers reported consuming ≥4 drinks in a day on at least one occasion during pregnancy. Over half [56 % (725/1,305) and 57 % (790/1,390) at each time point] of these mothers had consumed ≥4 drinks on only 1–2 days in the previous month. The majority (59 %; 774/1,305) of mothers who reported at least one occasion of consuming ≥4 drinks between 14 and 18 weeks also reported this pattern between 28 and 32 weeks gestation. Table 1 shows that maternal correlates of consuming ≥4 drinks included higher parity, smoking, use of cannabis and other illicit drugs, depression, being unmarried, rented tenure, and lower level of education.
