Since 1974 numerous clinical studies have made it clear that heavy alcohol consumption during pregnancy (in excess of 80 g or 8 units daily) can result in a child being born with a specific combination of physical and mental disabilities known as the Fetal Alcohol Syndrome. More moderate levels of intake (as little as 10 g of 1 unit daily) are associated with other fetal problems known as Fetal Alcohol Effects. The most common of these is growth retardation. Reduction of alcohol consumption is beneficial to pregnancy outcome. However, despite this great clinical and research interest within the field there has been comparatively little attention paid to researching possible preventative strategies and appropriate policy development. This paper first describes the size of the problem posed by drinking in pregnancy in the U.S.A. and the U.K., detailing the contrasting policy response on either side of the Atlantic. It examines the difficulties of formulating appropriate advice and then assesses the available research reports on preventative measures. The strategies described include general publicity and counselling for pregnant women. In addition, attention has been paid to the problems of dissemination by emphasising professional education. One major shortcoming is that most of these studies appear to have been carried out with little reference to existing knowledge on health education and promotion, or educational work in the antenatal or alcohol fields. In addition, little attention appears to have been paid to the characteristics of the groups at whom intervention might be targeted or the underlying social or psychological factors which maintain drinking in these groups. The second part of this paper, therefore, attempts to suggest appropriate avenues for developing preventative strategies by presenting a wide-ranging review with special reference to British experience. Particular attention is given to the issues of form and content of appropriate messages, targeting of risk populations, the venue for intervention, and media and the actual mechanisms involved in implementing the programme. We conclude that women should be advised to limit their alcohol consumption to no more than one unit a day when they are either pregnant or planning a pregnancy. We recommend that pregnant women should be asked about their alcohol and given appropriate advice during routine antenatal clinic visits. We suggest that the form of advice should be designed with the characteristics of the risk population in mind.(ABSTRACT TRUNCATED AT 400 WORDS)

This paper describes smoking and drinking patterns during pregnancy amongst a cohort of 2266 women who enrolled at a London antenatal clinic 1982-1983. Only 12% of mothers were non-drinkers before pregnancy, but 44% abstained in the first trimester, 38% in the second and 50% in the third. Before pregnancy 20% of mothers were drinking more than the recommended 10 units of alcohol per week. This dropped to 6% during pregnancy. Mean consumption at each of the three stages of pregnancy was highest amongst those mothers who were the heaviest drinkers before pregnancy. The heaviest pre-pregnancy drinkers were also the least likely to abstain at any point in pregnancy. Of those mothers who were drinking less than 10 units of alcohol per week before pregnancy, 3% increased during pregnancy. Wine was the most popular beverage choice but heavier drinkers were more likely to drink beers and spirits in addition. Before pregnancy 29% of mothers smoked. This dropped to 23% in pregnancy. Consumption levels fell amongst those who continued smoking. The heaviest pre-pregnancy smokers were the most likely to reduce but the least likely to stop. Smoking was positively associated with the level of both pre-pregnancy and pregnancy drinking. The most commonly cited reasons for changes in drinking and smoking habits in pregnancy were concern for the child, concern for self or concern for both. Feeling sick or ill was a more commonly stated reason for reduction of drinking than smoking. Social pressures were important in reducing smoking, but the mass media were quoted as a more important influence in reducing drinking. Mothers who drank more than 10 units of alcohol per week during pregnancy were more likely to be older, of higher social status and primiparous. In contrast those who smoked in pregnancy were more likely to be younger, of lower social status and multiparous. This has important implications for planning antenatal health education.

This paper provides basic epidemiological data on smoking and drinking patterns before pregnancy amongst 1117 pregnant women attending a London antenatal clinic. Similar data are already available from North America and surveys have been done in Scotland but there is a dearth of information from England and Wales. In the early stages of pregnancy, prior to recognition, heavy alcohol consumption (in excess of 56 units of alcohol per week) is associated with the Foetal Alcohol Syndrome. More moderate levels of intake (as little as 10 units of alcohol per week) have been associated with Foetal Alcohol Effects such as growth retardation. In our sample 19% of the mothers were drinking more than 10 units of alcohol per week. Six per cent were consuming more than the 14 units of alcohol currently recommended by three of the medical Royal Colleges as 'safe' for non-pregnant women. Average weekly alcohol consumption was related to both the usual frequency and amount drunk, but also to binge drinking, beverage choice and combination, and reasons for drinking. In general, drinking was frequent and light. Those women who drank more per week tended to drink more frequently than those in the lower weekly consumption bands. Fourteen per cent of the sample admitted to binge drinking (more than 14 units of alcohol in a single sitting). Wine was the most popular beverage type. The range of beverages consumed was wider in the higher alcohol consumption bands. Those in the lower bands were more likely to drink only one beverage type. Social reasons for drinking were of far greater importance than reasons which emphasised the effects of drinking. However, heavy drinkers were unlikely to drink solely for social reasons. Seventy-seven per cent of the mothers were non-smokers, but the incidence of smoking increased in the higher alcohol consumption bands. The demographic characteristics of the smokers were in marked contrast to those of the heavier drinkers. Smokers tended to be younger, of lower social status and multiparous, whereas the heavier drinkers were more likely to be older, of higher social status and primiparous. This finding is of fundamental importance to those interested in planning screening or intervention programmes.

This paper describes drinking and smoking patterns before and during pregnancy in 363 women from ethnic minorities living in West London. Drinking and smoking were less common and levels of consumption were lower amongst women of Apo-Caribbean, Asian or Oriental origin than amongst Europeans. However, 75% of the Apo-Caribbeans, 56% of the Orientals and 47% of the Asians did drink alcohol before pregnancy. Twenty-one per cent of the Europeans, 5% of the Apo-Caribbeans, 3% of the Orientals drank more than 100g alcohol per week (the level at which fetal harm may result). Drinking and smoking decreased in pregnancy in all ethnic groups, but 31% of Apo-Caribbeans, 29% of Orientals and 18% of Asians continued drinking. It is important to take alcohol and smoking histories from all pregnant women whatever their racial origin as part of good antenatal care. [ABSTRACT FROM AUTHOR]
