Abstract
Background: With evidence of offspring harms and concern for younger women's drinking behaviours, this study uses a hospital cohort to trend the use and changes in women's reported alcohol consumption. Aims: To examine (i) the trend of women's reported alcohol consumption over time, (ii) whether any increases in the frequency of alcohol consumption prior to a pregnancy are accompanied by increases in the frequency of alcohol consumption in pregnancy and (iii) the characteristics of women consuming alcohol at these times. Methods: Midwives collected routine data on 19,699 women between 2001 and 2006. Data on women's alcohol use prior to pregnancy and at their pregnancy-booking visit were analysed using a non-parametric test for trend and with bivariate and multivariate tests adjusting for possible confounders. Findings: The proportion of women reporting at-least weekly alcohol use prior to pregnancy was 25.4% and 5.9% at their pregnancy-booking visit. A significant linear increase over time ( p< 0.001) was found in the rate of women aged 20 years and older reporting at-least weekly alcohol use prior to pregnancy. Tertiary-educated women were more likely to consume alcohol at-least weekly prior to pregnancy. Women aged less than 20 years were less likely to report at-least weekly alcohol use at both time points. Having more children and Asian ethnicity were associated with a lower risk of at-least weekly alcohol use at these times. Conclusion: The majority of women reduce their alcohol consumption once they learn they are pregnant, with some evidence this trend may have increased in recent years.
