Categorical analyses of AADD revealed a very similar pattern: Antenatal report was significantly lower than retrospective report (AADD: χ2=23.16, df=3, p<0.001; see Table 5). Only 3 women reported fewer drinks per occasion retrospectively than antenatally. In addition, no women antenatally reported risk levels of daily drinking (AADD ≥ 2.5), whereas 21 women retrospectively reported risk levels of alcohol consumption per drinking day (AADD). With an additional 14 women who reported AADD > 2, a total of 35 women (12%) retrospectively reported drinking significant amounts of alcohol on days when they did drink during pregnancy. In contrast, no woman reported this level of alcohol consumption when asked during pregnancy.
