Alcohol Consumption In Pregnancy Research Articles

Early moderate prenatal alcohol exposure and maternal diet impact offspring DNA methylation across species.

Alcohol consumption in pregnancy can affect genome regulation in the developing offspring but results have been contradictory. We employed a physiologically relevant murine model of short-term moderate prenatal alcohol exposure (PAE) resembling common patterns of alcohol consumption in pregnancy in humans. Early moderate PAE was sufficient to affect site-specific DNA methylation in newborn pups without altering behavioural outcomes in adult littermates. Whole-genome bisulfite sequencing of neonatal brain and liver revealed stochastic influence on DNA methylation that was mostly tissue-specific, with some perturbations likely originating as early as gastrulation. DNA methylation differences were enriched in non-coding genomic regions with regulatory potential indicative of broad effects of alcohol on genome regulation. Replication studies in human cohorts with fetal alcohol spectrum disorder suggested some effects were metastable at genes linked to disease-relevant traits including facial morphology, intelligence, educational attainment, autism, and schizophrenia. In our murine model, a maternal diet high in folate and choline protected against some of the damaging effects of early moderate PAE on DNA methylation. Our studies demonstrate that early moderate exposure is sufficient to affect fetal genome regulation even in the absence of overt phenotypic changes and highlight a role for preventative maternal dietary interventions.

Homelessness in pregnancy

ObjectivesTo evaluate the association, if any, of homelessness or refuge accommodation on delivery and short term perinatal outcomes in an Irish tertiary maternity hospital. MethodsA retrospective cohort study of 133 singleton pregnancies in women reporting to be homeless or living in refuge at their booking antenatal appointment between 2013 and 2022. Analysis compared sociodemographic characteristics and perinatal outcomes in this cohort to a reference population of 76,858 women with stable living arrangements. ResultsWomen in the homeless/refuge population were statistically more likely to be single (75.2 % vs 39.5 %, p < 0.001), have an unplanned pregnancy (73.7 % vs 27.2 %, p < 0.001), report a history of psychiatric illness (42.9 % vs 22.4 %, p < 0.001), domestic violence (18.8 % vs 0.9 %, p < 0.001) alcohol consumption in pregnancy (3.0 % vs 0.8 %, p < 0.001) or smoking in pregnancy (41.3 % vs 9.7 %, p < 0.001).They were significantly more likely to have a preterm birth (adjusted OR 1.71 (1.01–2.87) p = 0.04). They also had a significantly lower median birth weight compared to the reference population (birthweight 3270 g vs 3420 g, p < 0.001). ConclusionWomen in the homeless and refuge population are more likely to experience poorer perinatal outcomes compared to women with stable living arrangements.

Severe manifestation of foetal alcohol syndrome – case report

Foetal alcohol syndrome is a term describing the set of conditions caused by maternal alcohol consumption in pregnancy. A complete evaluation includes an assessment of the three key diagnostic criteria – central nervous system damage, growth deficiency, and characteristic facial features (microcephaly, small palpebral fissures, low nasal bridge, smooth philtrum, thin upper lip). A premature one-day-old female infant with dysmorphic features, in severe general condition, was admitted to the Neonatal Intensive Care Unit due to respiratory distress and suspected heart defect. Hypotrophy, bronchopulmonary dysplasia, and both ventricular and atrial septal defect were diagnosed. The authors of this paper aim to raise awareness about the lifelong and irreversible nature of foetal alcohol syndrome, which significantly impacts various aspects of a child’s life. However, it is also highlighted that foetal alcohol syndrome belongs to a small group of conditions that can be entirely prevented.

Alcohol per capita and prevalence of alcohol exposed pregnancies: systematic review and meta-analysis

Abstract Background Alcohol is a teratogen that crosses the placenta. While studies have estimated the global burden of alcohol use in pregnancy, reliable and valid data on alcohol consumption during pregnancy in many countries is lacking. Alcohol consumption per capita (APC) data are available worldwide. This systematic review, by investigating the association between APC and alcohol consumption in pregnancy by country, aims to evaluate the accuracy of using APC data to predict the prevalence of prenatal alcohol exposure (PAE). Methods This study combines studies identified in a systematic review by Popova et al. 2017 and a systematic search of MEDLINE from 2015 through 6th October 2022, to identify additional papers. Papers identified in either search were on the prevalence of PAE or fetal alcohol syndrome (FAS). Two authors independently screened titles, abstracts, full-text articles and performed data extraction and quality assessment. APC data,per country, by year, was obtained from the World Health Organization (WHO) website. A meta-analysis, assuming a random effects model will be performed. Sensitivity analyses, including restricting by population, timing of exposure, time and method of ascertainment of alcohol consumption will be carried out. Results Of 24,935 PAE and 12,231 FAS prevalence articles identified, 400 PAE studies and 77 FAS studies met the inclusion criteria. Studies represent data from 1959-2020 from all 6 WHO regions, with APC between 0.012-14.78. Preliminary analysis suggests a statistically significant correlation between prevalence of alcohol consumption during pregnancy and APC. Conclusions Preliminary results from this study suggest that publicly available data on APC can be used to predict the population-based prevalence of alcohol use in pregnancy in different countries. Effective policies and interventions are required to reduce APC and thus, alcohol use in pregnancy and associated detrimental child health outcomes around the globe. Key messages • Knowing the prevalence of FAS and its main risk factor- prenatal alcohol use, will inform the setting of priorities for public health policy, public health initiatives, and health-care planning. • By investigating the association between alcohol intake in pregnancy and APC we will assess whether APC can predict alcohol intake in pregnancy.

Risk factors associated with higher scores in internalizing and externalizing behaviors in Chilean preschoolers.

Early detection of behavioral disorders in children is necessary for intervention. Available data show a high prevalence of child and adolescent psychiatric disorders in Chile (22.5%), but behavioral problems in younger children have not been evaluated. This work assesses behavioral disorders in preschoolers and their association with sociodemographic variables of the family and the child. The data was collected during the impact assessment of the Biopsychosocial Development Support Program "Chile Crece Contigo", using a multistage and representative random sample of 1377 preschoolers, aged between 30 and 48 months, who attended public health services. Homes were visited to apply a questionnaire and the Child Behavior Checklist (CBCL, 1.5-5 years). Results: Multivariable regression model for total raw scores shows that child's age, the number of chronic diseases in the child, and history of exposure to mother's alcohol consumption in pregnancy, remain significant when adjusted for all variables included (R2 of 17.8% and η2 of .19 (95% CI: .14-.22)). In externalizing and internalizing explanatory models, child's chronic diseases and a higher score of authoritarian beliefs about parenting show the two largest effect sizes. These results add to the evidence of urgent problems in preschool mental health.

The effects of acamprosate on maternal and neonatal outcomes in a mouse model of alcohol use disorders

BackgroundDespite the teratogenic effects of alcohol, little is known about the safety of pharmacotherapies such as acamprosate for the treatment of alcohol use disorders in pregnancy. The aims of this study were to investigate, in a mouse model, the effects of maternally administered acamprosate on maternal and neonatal health, offspring neurodevelopment and behaviour, as well as examine whether acamprosate reduces the neurological harm associated with alcohol consumption in pregnancy. MethodsDams were randomly allocated to one of four treatment groups: (i) control (water), (ii) acamprosate (1.6 g/L), (iii) alcohol (5% v/v) or (iv) acamprosate and alcohol (1.6 g/L; 5% v/v ethanol) and exposed from 2-weeks pre-pregnancy until postpartum day 7. Gestational outcomes including litter size and sex ratio were assessed, in addition to early-life markers of neurodevelopment. At 8 weeks of age, motor coordination, anxiety, locomotion, and memory of the adult offspring were also examined. ResultsExposure to acamprosate did not affect maternal and birth outcomes (mating success, gestational weight gain, litter size, sex ratio), neonatal outcomes (head and body length, postnatal weight) or neurodevelopmental markers (righting reflex and negative geotaxis). Acamprosate exposure did not affect offspring motor control, locomotion or anxiety, however the effects on short-term memory remain uncertain. Prenatal alcohol exposed offspring exhibited various alterations, such as lower postnatal weight, smaller head (p = 0.04) and body lengths (p = 0.046) at postnatal day 70 (males only), increased negative geotaxis speed (p = 0.03), an increased time spent in the inner zone of the open field (p = 0.02). Acamprosate mitigated the effects of alcohol for negative geotaxis at postnatal day 7 (p = 0.01) and female offspring weight at postnatal day 70 (p = 0.03). ConclusionsOverall, we show that prenatal acamprosate exposure was not associated with poor maternal or neonatal health outcomes or impaired neurodevelopment and behaviour. However, acamprosate's effects on short-term memory remain uncertain. We present preliminary evidence to suggest acamprosate displayed some neuroprotective effects against damage caused by in utero alcohol exposure.

Differential effectiveness of a practice change intervention to improve antenatal care addressing alcohol consumption during pregnancy: Exploratory subgroup analyses within a randomised stepped-wedge controlled trial

ObjectiveA practice change intervention demonstrated improvements in the provision of antenatal care addressing alcohol consumption. The aim of this study was to explore whether the effectiveness of the intervention differed between subgroups of pregnant women and types and location of maternity services. Design and SettingPost-hoc exploratory subgroup analyses of the outcomes from a randomised stepped-wedge controlled trial conducted with all public maternity services within three sectors of a local health district in Australia. MeasurementsTwo outcomes (receipt of alcohol assessment and complete care) measured at two visit types (initial and subsequent) were included in analyses. Logistic regression models explored interactions between pre-post differences and subgroups of women (age, Aboriginal origin, education level, disadvantage, gravidity and alcohol consumption in pregnancy) and services (geographic remoteness, service and provider type/s) that have been reported to be associated with variation in guideline implementation. FindingsSurveys from 5694 women were included in the analyses. For the initial visit, no significant differential intervention effects between subgroups of women or type/location of services were found for either outcome. For subsequent visits, the intervention effect differed significantly only between Aboriginal origin subgroups (Aboriginal OR: 1.95; 95% CI: 0.99-3.85; non-Aboriginal OR: 5.34; 95% CI: 4.17-6.83; p<0.01) and women's alcohol consumption in pregnancy subgroups (consumed alcohol OR: 1.28; 95% CI: 0.59-2.78; not consumed alcohol OR: 5.22; 95% CI: 4.11-6.65; p<0.001) for assessment of alcohol consumption. Key conclusionsThese exploratory results suggest that the intervention may have had similar effects between different subgroups of women and types and location of services, with the exception of women who were non-Aboriginal and women who had not consumed alcohol, for whom the intervention was potentially more effective. Implications for practiceThe practice change intervention could be implemented with different maternity service and provider types to effectively support improvements in antenatal care addressing alcohol consumption. These exploratory results provide further data for hypothesis generation regarding targeted areas for the testing of additional strategies that enable Aboriginal women to benefit equally from the intervention, and to ensure those women most in need of care, those consuming alcohol during pregnancy, have their care needs met.

Influence of Maternal Ethanol Exposure on Systemic Hemodynamic Variables and Histopathological Changes in the Aorta Wall of Male Rat Offspring: A Three-month Follow-up.

Background: Alcohol consumption in pregnancy is associated with an increased risk of cardiovascular abnormalities, but the mechanisms are unknown. This study evaluated the impact of ethanol exposure on the offspring’s aorta structural, functional, and molecular alterations on postnatal (PN) both on days 21 and 90.Methods:This experimental study was conducted at Urmia University of Medical Sciences (Urmia, Iran) in 2019. Twenty Pregnant Wistar rats on the seventh day of Gestation Day (GD) were randomly divided into two groups: control and ethanol-treated groups (n=10 per group). From the seventh day of GD throughout lactation, rats in the ethanol group were fed binge alcohol (4.5 g/Kg body weight) once daily. Systemic hemodynamic variables in the offspring were analyzed using waveform contour analysis 90 days after birth. On postnatal days (PN) 21 and 90, aorta wall histological alterations and the level of inflammatory factors were assessed in the aorta of male offspring. The statistical differences were examined via an independent samples t test. P<0.05 was considered to be statistically significant. Results: The results revealed that offspring in the ethanol group had higher systolic, diastolic, mean arterial pressure, and dicrotic pressure than the control group (P<0.001). The level of aorta tissue tumor necrosis factor (TNF)-α, intercellular adhesion molecule (ICAM)-1, nuclear factor (NF)-κ, and endothelin-1 were significantly higher in the ethanol offspring group than in the control group (P<0.001). Histopathological changes such as total aorta thickness, tunica media, tunica adventitia, elastin fiber thickness, fiber interval, and elastin/media ratio significantly increased in the aorta of the offspring of the ethanol group compared to the control group 21 and 90 days after birth.Conclusion: Our findings suggest that prenatal and early postnatal ethanol exposure-induced cardiovascular abnormalities are, in part, due to predisposing the aorta to atherosclerosis, which was mediated through the aorta wall remodeling and inflammation process.

Maternal cigarette smoking and alcohol consumption and congenital diaphragmatic hernia.

BackgroundCongenital diaphragmatic hernia (CDH) occurs when abnormal diaphragm development allows herniation of abdominal organs into the thoracic cavity. Its etiopathogenesis is not well understood, but cigarette smoking and alcohol exposure may impact diaphragm development. Using data from a large, population‐based case–control study, we examined associations between maternal cigarette smoking and alcohol consumption and CDH in offspring.MethodsWe analyzed maternal interview reports of cigarette smoking and alcohol consumption during early pregnancy for 831 children with CDH and 11,416 children without birth defects with estimated dates of delivery during 1997–2011. Generalized linear mixed effects models with a random intercept for study site were used to estimate associations between measures of exposure to smoking (any, type, frequency, duration) and alcohol (any, quantity, frequency, variability, type) for all CDH combined and selected subtypes (Bochdalek and Morgagni).ResultsMothers of 280 (34.0%) case and 3,451 (30.3%) control children reported early pregnancy exposure to cigarette smoking. Adjusted odds ratios for all CDH were increased for any (1.3; 95% confidence interval 1.1–1.5), active (1.3, 1.0–1.7), and passive (1.4, 1.1–1.7) smoking. Early pregnancy alcohol consumption was reported by mothers of 286 (34.9%) case and 4,200 (37.0%) control children; odds were near the null for any consumption (0.9, 0.8–1.1) and consumption with (0.9, 0.7, 1.1) or without (0.9, 0.8, 1.1) binging. Estimates for smoking and alcohol tended to be higher for Bochdalek CDH and Morgagni CDH than those for all CDH.ConclusionsFindings suggest that maternal early pregnancy exposure to cigarette smoking, but less so to alcohol consumption, contributes to CDH. These findings need to be replicated in additional large studies that use systematic case ascertainment and classification, detailed exposure assessment, and examine subtype‐specific associations.

Effectiveness of Digital Interventions for Preventing Alcohol Consumption in Pregnancy: Systematic Review and Meta-analysis.

BackgroundAlcohol consumption in pregnancy has been associated with serious fetal health risks and maternal complications. While previous systematic reviews of digital interventions during pregnancy have targeted smoking cessation and flu vaccine uptake, few studies have sought to evaluate their effectiveness in preventing alcohol consumption during pregnancy.ObjectiveThis systematic review aims to assess (1) whether digital interventions are effective in preventing alcohol consumption during the pregnancy/pregnancy-planning period, and (2) the differential effectiveness of alternative digital intervention platforms (ie, computers, mobiles, and text messaging services).MethodsPubMed, Embase, CINAHL, and Web of Science were searched for studies with digital interventions aiming to prevent alcohol consumption among pregnant women or women planning to become pregnant. A random effects primary meta-analysis was conducted to estimate the combined effect size and extent to which different digital platforms were successful in preventing alcohol consumption in pregnancy.ResultsSix studies were identified and included in the final review. The primary meta-analysis produced a sample-weighted odds ratio (OR) of 0.62 (95% CI 0.42-0.91; P=.02) in favor of digital interventions decreasing the risk of alcohol consumption during pregnancy when compared to controls. Computer/internet-based interventions (OR 0.59, 95% CI 0.38-0.93) were an effective platform for preventing alcohol consumption. Too few studies of text messaging (OR 0.29, 95% CI 0.29-2.52) were available to draw a conclusion.ConclusionsOverall, our review highlights the potential for digital interventions to prevent alcohol consumption among pregnant women and women planning to become pregnant. Considering the advantages of digital interventions in promoting healthy behavioral changes, future research is necessary to understand how certain platforms may increase user engagement and intervention effectiveness to prevent women from consuming alcohol during their pregnancies.

Physical Activity in Pregnancy was Favorably Associated with Maternal And Offspring Health Indices

Regular physical activity (PA) in pregnancy can benefit the pregnant woman through a shorter birth and a shorter recovery period. The study aimed to investigate the effect of PA in pregnancy, on maternal and offspring health indicators. Population-based data were obtained from a national database that included anthropometric and physical fitness data of almost all Greek children 8 to 9 years. Α random sample of 5,125 dyads of mothers-children was evaluated. Telephone interviews were carried out with the use of a standardized questionnaire for the collection of maternal lifestyle factors. Children born to mothers who participated in the recommended PA levels had lower odds (OR=0.78, 95% CI: 0.69-0.95) to be overweight/obese in childhood. Adequate PA levels in pregnancy were found to be associated with lower odds of preterm birth by 61% (OR = 0.39, 95% CI: 0.17-0.87), and alcohol consumption in pregnancy by 62% (OR = 0.38, 95% CI: 0.27-0.56) as compared to the inadequate level of PA. Also, mothers with adequate PA in pregnancy had decreased odds for excessive GWG and final BMI by almost 40% in comparison to those with inadequate PA levels. PA in pregnancy does seem to be related to offspring health indicators (e.g. obesity at 8 years) and is associated with a more favorable maternal health profile.

Prenatal Alcohol Intake and Knowledge of its Effect: A Survey of Pregnant Women Attending a General Hospital in South East, Nigeria

Background: Alcohol consumption during pregnancy is a major public health concern due to its noxious effect on both the mother and fetus. Aim: The study aim was to determine the prevalence of prenatal alcohol intake, knowledge of its effects, and associated factors among pregnant women attending antenatal clinic, Poly General Hospital, Enugu. Materials and Methods: A descriptive cross-sectional survey was adopted and simple random sampling was employed to select 248 pregnant women from the total population. Data were obtained using structured questionnaires, summarized using descriptive statistics, and presented in tables. Statistical analysis for associations between level of educational attainment, occupation of the pregnant woman, and knowledge of the effects of alcohol consumption was performed using Chi-square tests. Results: The prevalence of alcohol use during pregnancy was 40.3% with beer (48.8%) and palm wine (48.8%) being the major alcoholic beverages taken. Majority (59.7%) of the participants had good knowledge of the effects of alcohol consumption in pregnancy while less than half (33.9%) had good knowledge of the effect on the unborn baby. Previous drinking habits before pregnancy (3.48 ± 0.84) and unwanted pregnancy (3.17 ± 0.93) were the major perceived factor influencing their alcohol intake. Educational level was not significantly related to knowledge of alcohol effects on pregnancy. Conclusion: Regardless of the knowledge of the harmful effect of alcohol on the fetus and maternal health, a significant proportion of mothers continue to consume alcohol during pregnancy. Therefore, there is a need for widespread education of women of childbearing age focused on driving behavioural change with regards to alcohol intake in pregnancy.

Why do women consume alcohol during pregnancy or while breastfeeding?

IssueAlcohol consumption during pregnancy and breastfeeding cause adverse health outcomes to the mother and child, including Fetal Alcohol Spectrum Disorder (FASD).ApproachSystematic literature review and thematic synthesis. Original studies that contained reasons for alcohol consumption in pregnancy and while breastfeeding were included. The Mixed Methods Appraisal Tool (MMAT) and the Confidence in the Evidence of Reviews of Qualitative Research (CerQUAL) approach were utilised. The review protocol is available on PROSPERO (registration number: CRD42018116998).Key FindingsForty‐two eligible studies comprising women from 16 countries were included. Most commonly reported reasons of alcohol use in pregnancy were societal pressure and the belief that only “strong” alcohol and alcohol in large quantities is harmful. Other reasons were: a lack of awareness of adverse effects on the fetus; coping with adverse life experiences; consumption based on intuitive decision‐making and influenced by personal/peer experiences; belief in the beneficial properties of alcohol; advice from medical practitioners; unwanted or unplanned pregnancy; alcohol dependence; and consumption as a cultural/traditional custom. Reasons for alcohol use during breastfeeding included the belief that alcohol stimulates breast milk production, unclear advice from medical practitioners, unawareness of the risks of infant exposure and to improve mood and celebrate events.ImplicationsUnderstanding the context of reasons for alcohol use in pregnancy is crucial for implementing prenatal health education, and preventing FASD and other adverse maternal and child health outcomes.ConclusionIndividual beliefs, knowledge/advice, culture and personal circumstances influence alcohol use in pregnancy. Data are limited for reasons surrounding alcohol use while breastfeeding.

Effect of Maternal Prepregnancy/Early-Pregnancy Body Mass Index and Pregnancy Smoking and Alcohol on Congenital Heart Diseases: A Parental Negative Control Study.

BackgroundCongenital heart diseases (CHDs) are the most common congenital anomaly. The causes of CHDs are largely unknown. Higher prenatal body mass index (BMI), smoking, and alcohol consumption are associated with increased risk of CHDs. Whether these are causal is unclear.Methods and ResultsSeven European birth cohorts, including 232 390 offspring (2469 CHD cases [1.1%]), were included. We applied negative exposure paternal control analyses to explore the intrauterine effects of maternal BMI, smoking, and alcohol consumption during pregnancy, on offspring CHDs and CHD severity. We used logistic regression, adjusting for confounders and the other parent's exposure and combined estimates using a fixed‐effects meta‐analysis. In adjusted analyses, maternal overweight (odds ratio [OR], 1.15 [95% CI, 1.01–1.31]) and obesity (OR, 1.12 [95% CI, 0.93–1.36]), compared with normal weight, were associated with higher odds of CHD, but there was no clear evidence of a linear increase in odds across the whole BMI distribution. Associations of paternal overweight, obesity, and mean BMI were similar to the maternal associations. Maternal pregnancy smoking was associated with higher odds of CHD (OR, 1.11 [95% CI, 0.97–1.25]) but paternal smoking was not (OR, 0.96 [95% CI, 0.85–1.07]). The positive association with maternal smoking appeared to be driven by nonsevere CHD cases (OR, 1.22 [95% CI, 1.04–1.44]). Associations with maternal moderate/heavy pregnancy alcohol consumption were imprecisely estimated (OR, 1.16 [95% CI, 0.52–2.58]) and similar to those for paternal consumption.ConclusionsWe found evidence of an intrauterine effect for maternal smoking on offspring CHDs, but no evidence for higher maternal BMI or alcohol consumption. Our findings provide further support for the importance of smoking cessation during pregnancy.

Estimated Prevalence of Harmful Alcohol Consumption in Pregnant and Nonpregnant Women in Saxony-Anhalt (NorthEast Germany) Using Biomarkers.

Alcohol consumption is commonly accepted in Western societies and is a known risk factor in pregnancy, which could lead to fetal alcohol spectrum disorders (FASDs). Prevalence of alcohol consumption during pregnancy is mostly unknown. Prevalence estimates in publications based on questionnaires are limited by possible underreporting due to social stigmatization. The aim of this study was to estimate the prevalence of harmful alcohol consumption in a large cohort of pregnant women using different biomarkers related to alcohol consumption and compare the findings with those of non-pregnant women METHODS: Routine parameters known to be influenced by alcohol consumption (γ-glutamyltransferase, GGT; carbohydrate-deficient transferrin, CDT/%CDT; mean corpuscular/cell volume, MCV; combined parameter of GGT and %CDT, GGT-CDT) were analyzed in serum samples of 2,182 pregnant women and 743 non-pregnant, age-matched females. Data were tested for (i) differences between pregnant and non-pregnant women and (ii) changes across the 3 trimesters of pregnancy. Prevalence rates differ greatly according to the parameter and cutoff, which reflects the limitations of assessing alcohol consumption with biomarkers. The prevalence of harmful alcohol consumption on the basis of a single or several elevated parameters was 13.8% (95% CI: 12.4 to 15.2) in pregnant women and 18.6% (95% CI: 15.8 to 21.4) in non-pregnant women, though 85.0% of the elevated measurements were attributable to an isolated elevation in %CDT only. Using GGT-CDT as the parameter with the highest specificity according to the literature, the estimated prevalence of harmful alcohol consumption in pregnancy is 0.5% (95% CI: 0.2 to 0.7). Estimated prevalence rates differ greatly with respect to the biomarkers and cutoffs used. The use of CDT/%CDT alone appears to overestimate harmful alcohol consumption during pregnancy.

Guideline No. 405: Screening and Counselling for Alcohol Consumption During Pregnancy.

To establish national standards of care for screening and counselling pregnant women and women of child-bearing age about alcohol consumption and possible alcohol use disorder based on current best evidence. Health care providers who care for pregnant women and women of child-bearing age. Pregnant women and women of child-bearing age and their families. Medline, EMBASE, and CENTRAL databases were searched for "alcohol use and pregnancy." The results were filtered for a publication date between 2010 and September 2018. The search terms were developed using Medical Subject Headings terms and keywords, including pre-pregnancy, pregnant, breastfeeding, lactation, female, women, preconception care, prenatal care, fetal alcohol spectrum disorder, prenatal alcohol exposure, drinking behavior, alcohol abstinence, alcohol drinking, binge drinking, alcohol-related disorders, alcoholism, alcohol consumption, alcohol abuse, benzodiazepines, disulfiram, naltrexane, acamprosate, ondansetron, topiramate, cyanamide, calcium carbimide, alcohol deterrents, disease management, detoxification, Alcoholics Anonymous, alcohol counselling, harm reduction, pre-pregnancy care, prenatal care, incidence, prevalence, epidemiological monitoring, and brief intervention. Evidence was included from clinical trials, observational studies, reviews, systematic reviews and meta-analyses, guidelines, and conference consensus. The content and recommendations in this guideline were drafted and agreed upon by the authors. The Board of Directors of the Society of Obstetricians and Gynaecologists of Canada approved the final draft for publication. The quality of evidence was rated using the criteria described in the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology framework. Implementation of the recommendations in these guidelines using validated screening tools and brief intervention approaches may increase obstetrical care provider recognition of alcohol consumption and problematic alcohol use among women of child-bearing age and those who are pregnant. It is anticipated that health care providers will become confident and competent in managing and supporting these women so they can achieve optimal health and pregnancy outcomes.

An antenatal alcohol service evaluation of the north-east of England and north Cumbria

NHS England's 'Better Births' strategy aims to improve maternal and infant health outcomes. A strategic priority identified in the north-east local maternity system is to reduce alcohol consumption in pregnancy due to the documented diverse risks of harm to mother and baby, including foetal alcohol spectrum disorder. To evaluate current alcohol prevention, screening and treatment service provision in maternity care across the region, and inform future recommendations. A service evaluation survey was developed to systematically consult strategic stakeholders across all nine maternity trusts in the region over a 2-month period in 2018. Content analysis was employed to identify fundamental themes and inform recommendations for practice. High variation was reported throughout regional clinical practices, service provision and staff training. For example, a number of alcohol screening tools were identified, each with diverse thresholds for referral; reported data collection and documentation practices were multifarious, incomparable and unquantifiable; audit was rare and guidelines were primarily influenced by local commissioning agreements. Standardized patient pathways involving alcohol screening and management practices are required, and sharing best practices will facilitate referrals and support regardless of location. The implementation of these recommendations requires appropriate leadership, commissioning and training strategies.
