The Coombe Women’s Hospital (Dublin) study of alcohol use in pregnancy Study funded by the Heath Promotion Unit, Department of Health & Children Dublin, Ireland
Irish Research into Alcohol (& Smoking) in Pregnancy
1992 v % of antenatal women were aware of the potential harmful effects of alcohol in pregnancy & 11% advised by doctor about hazards of alcohol. 2.93% of antenatal women were aware of smoking hazards & 53% advised by doctor about smoking risks. Daly et al (1992), Irish Medical Journal; 85(4): Alcohol was consumed by 89% of women in pregnancy & 10% admitted to binge drinking 2.44% were aware of the associated risks of alcohol use in pregnancy 3.28% indicated that they received advice about the alcohol related risk from a health care professional but of these 71% reported that it did not alter their behaviour 4.71% of pregnant smokers were aware of the risks which led to a change in behaviour in 42% McMillan et al (2006), Irish Medical Journal, 99 (9): 283
Today’s presentation will focus on... The prevalence and patterns of alcohol use reported by a sample of pregnant women attending a Dublin Maternity Hospital between 1987 and How alcohol consumption in Irish-born women relates to use in a similar population from other countries also attending this hospital.
The Coombe Women’s Hospital Computerised Database Set up in 1986, with the purpose of Generating anonymised data for Annual Report & service planning purposes. Data collection by nursing staff at antenatal booking clinic & in the labour ward Data entry by non-clinical staff “The system” was changed & upgraded in July 1999 & more fields added, and the format of some questions was changed...
Size of the data file N = 82,627 (1 January ‘87 – 30 June ’99) 43,318 (July ‘99 – 30 March 2005) Total: 125,945 mothers
Annual trends in reported maternal alcohol use (percentages) before pregnancy ( ) Never drank Occasional Several days/ alcohol use week
Annual trends in reported maternal alcohol use (percentages) before pregnancy ( ) Year No alcohol 6 units/ before pregnancy week week The percentage that reported that they did not drink before pregnancy dropped from 1988 until the late 1990s & has risen again..
Reported alcohol use by pregnant women ( ) No alcohol 11,962 (27.6%) <5units/week 24,300 (56.1%) >6-9 units/week 2,362 (5.5%) >10 units/week 709 (1.6%)* Missing data 3,985 (9.2%) Total 43,318 (100%) *61 pregnant women (0.14%) reported drinking more than 20 units/week.
Nationality and reported alcohol use (percentages) in pregnant mothers No 6-9units/ >10 units/ N=35,382 alcoholweek week week Rep of Ireland ,454 UK ,868 Other EU Non-EU ,505 Irish & UK-born mothers had a lower likelihood of reporting themselves to be non-drinkers in pregnancy. Marked difference between Irish & UK born mothers and the rest of EU & the non-EU mothers when it comes to reported alcohol consumption of more than 6 units/week.
Reported maternal alcohol use (percentage) by age, in pregnancy for Irish mothers ( ) Age bands No Alcohol 6-9 units >10 units N=25, , , , , Two-thirds of all pregnant under-18 year olds reported drinking in pregnancy. Highest percentage drinking >10units/week was in the year old age band. In most age categories 1:10 women drink more than 6 units/week 0.3% of the year olds and the year olds reported consuming more than 20 units/week, whereas 0.1% of all of the other age bands reported such usage.
Summary Over two-thirds of all pregnant under-18 year olds reported drinking alcohol during pregnancy Irish and UK-born mothers were more likely to report themselves as consuming more than 6 units a week as compared with EU and non- EU nationals The highest percentage category reporting drinking over 10 units per week was the 18 – 24 year olds 7.1% of all pregnant women admitted to drinking more than 6 units of alcohol per week 0.14% pregnant women reported that they drank more than 20 units.
Conclusions & actions There is a problem. Progress on tobacco (part of larger study) but not on alcohol. More systematic data collection is needed. An unambiguous public health message is called for…Minister for Health & Children mentioned labelling alcohol products when she launched the Report…
