Objective: To measure the knowledge, attitudes and practices of health professionals regarding fetal alcohol syndrome (FAS) and alcohol use during pregnancy. Method: A postal survey of a representative random sample of health professionals was conducted in Western Australia (WA) in 2002/03. 1,143 (79%) of 1,443 eligible health professionals completed the survey (87 Aboriginal Health Workers, 286 allied health professionals, 537 community nurses, 170 general practitioners and 63 obstetricians). Results: Of 1,143 health professionals, 12% identified all four essential diagnostic features of FAS. Most (95%) had never diagnosed FAS. Although 82% believed that making a diagnosis of FAS might improve treatment plans and 85% agreed FAS was preventable, 53% said the diagnosis might be stigmatising. Only 2% felt very prepared to deal with FAS and most wanted information for themselves and their clients. Of the 659 health professionals caring for pregnant women, only 45% routinely ask about alcohol use in pregnancy, only 25% routinely provide information on the consequences of alcohol use in pregnancy and only 13% provide advice consistent with NHMRC guidelines on alcohol consumption in pregnancy. Conclusion: Health professionals have identified the need for educational materials for themselves and their clients. Implications: FAS is likely to be under‐ascertained in Australia due to a lack of knowledge of FAS by health professionals. Until this lack of knowledge is addressed, opportunities for diagnosis and prevention of FAS will be limited.

BackgroundThis paper presents drinking patterns in a prospective study of a population-based cohort of 1570 pregnant women using a combination of dose and timing to give best estimates of prenatal alcohol exposure (PAE). Novel assessments include women’s special occasion drinking and alcohol use prior to pregnancy recognition.MethodsInformation on up to nine types of alcoholic drink, with separate frequencies and volumes, including drinking on special occasions outside a ‘usual’ pattern, was collected for the periconceptional period and at four pregnancy time points. Weekly total and maximum alcohol consumption on any one occasion was calculated and categorised. Drinking patterns are described in the context of predictive maternal characteristics.Results41.3 % of women did not drink during pregnancy, 27 % drank in first trimester only; most of whom stopped once they realised they were pregnant (87 %). When compared to women who abstained from alcohol when pregnant, those who drank in the first trimester only were more likely to have an unplanned pregnancy and not feel the effects of alcohol quickly. Almost a third of women continued to drink alcohol at some level throughout pregnancy (27 %), around half of whom never drank more than at low or moderate levels. When compared with abstainers and to women who only drank in trimester one, those who drank throughout pregnancy tended to be in their early to mid-thirties, smoke, have a higher income and educational attainment.Overall, almost one in five women (18.5 %) binge drank prior to pregnancy recognition, a third of whom were identified with a question about ‘special occasion’ drinking. Women whose age at first intoxication was less than 18 years (the legal drinking age in Australia), were significantly more likely to drink in pregnancy and at binge levels prior to pregnancy recognition.ConclusionsWe have identified characteristics of pregnant women who either abstain, drink until pregnancy awareness or drink throughout pregnancy. These may assist in targeting strategies to enhance adherence to an abstinence policy and ultimately allow for appropriate follow-up and interpretation of adverse child outcomes. Our methodology also produced important information to reduce misclassification of occasional binge drinking episodes and ensure clearly defined comparison groups.

Objective To investigate the relationship between prenatal alcohol exposure and fetal growth and preterm birth and to estimate the effect of dose and timing of alcohol exposure in pregnancy.Design A population-based cohort study linked to birth information on the Western Australian Midwives Notification System. Setting Western Australia.Population A 10% random sample of births restricted to nonindigenous women who had delivered a singleton infant (n = 4719) in 1995-1997. MethodsThe impact of alcohol consumption in pregnancy on fetal growth (small-for-gestational-age [SGA] and large-forgestational-age infants [LGA]) and preterm birth (<37 weeks of gestation) was assessed using multivariate logistic regression analysis and adjusting for confounding factors.Main outcome measures Odds ratios and 95% CI, attributable risk, and population attributable risk were calculated.Results The percentage of SGA infants and preterm birth increased with higher levels of prenatal alcohol exposure; however, the association between alcohol intake and SGA infants was attenuated after adjustment for maternal smoking. Low levels of prenatal alcohol were not associated with preterm birth; however, binge drinking resulted in a nonsignificant increase in odds. Preterm birth was associated with moderate and higher levels of prenatal alcohol consumption for the group of women who ceased drinking before the second trimester. This group of women was significantly more likely to deliver a preterm infant than women who abstained from alcohol (adjusted OR 1.73 [95% CI 1.01-3.14]).Conclusions Alcohol intake at higher levels, particularly heavy and binge drinking patterns, is associated with increased risk of preterm birth even when drinking is ceased before the second trimester. This finding, however, is based on small numbers and needs further investigation. Dose and timing of prenatal alcohol exposure appears to affect preterm delivery and should be considered in future research and health education.

IMPORTANCEChildren who receive a diagnosis of fetal alcohol spectrum disorder may have a characteristic facial appearance in addition to neurodevelopmental impairment. It is not well understood whether there is a gradient of facial characteristics of children who did not receive a diagnosis of fetal alcohol spectrum disorder but who were exposed to a range of common drinking patterns during pregnancy.OBJECTIVE To examine the association between dose, frequency, and timing of prenatal alcohol exposure and craniofacial phenotype in 12-month-old children. DESIGN, SETTING, AND PARTICIPANTSA prospective cohort study was performed from January 1, 2011, to December 30, 2014, among mothers recruited in the first trimester of pregnancy from low-risk, public maternity clinics in metropolitan Melbourne, Australia. A total of 415 white children were included in this analysis of 3-dimensional craniofacial images taken at 12 months of age. Analysis was performed with objective, holistic craniofacial phenotyping using dense surface models of the face and head. Partial least square regression models included covariates known to affect craniofacial shape.EXPOSURES Low, moderate to high, or binge-level alcohol exposure in the first trimester or throughout pregnancy.MAIN OUTCOMES AND MEASURES Anatomical differences in global and regional craniofacial shape between children of women who abstained from alcohol during pregnancy and children with varying levels of prenatal alcohol exposure. RESULTSOf the 415 children in the study (195 girls and 220 boys; mean [SD] age, 363.0 [8.3] days), a consistent association between craniofacial shape and prenatal alcohol exposure was observed at almost any level regardless of whether exposure occurred only in the first trimester or throughout pregnancy. Regions of difference were concentrated around the midface, nose, lips, and eyes. Directional visualization showed that these differences corresponded to general recession of the midface and superior displacement of the nose, especially the tip of the nose, indicating shortening of the nose and upturning of the nose tip. Differences were most pronounced between groups with no exposure and groups with low exposure in the first trimester (forehead), moderate to high exposure in the first trimester (eyes, midface, chin, and parietal region), and binge-level exposure in the first trimester (chin).CONCLUSIONS AND RELEVANCE Prenatal alcohol exposure, even at low levels, can influence craniofacial development. Although the clinical significance of these findings is yet to be determined, they support the conclusion that for women who are or may become pregnant, avoiding alcohol is the safest option.
