Abstract
Ancestrally admixed populations are underrepresented in genetic studies of complex diseases, which are still dominated by European-descent populations. This is relevant not only from a representation standpoint but also because of admixed populations' unique features, including being enriched for rare variants, for which effect sizes are disproportionately larger than common polymorphisms. Furthermore, results from these populations may be generalizable to other populations. The South African Cape Coloured (SACC) population is genetically admixed and has one of the highest prevalences of fetal alcohol spectrum disorders (FASD) worldwide. We profiled its admixture and examined associations between ancestry profiles and FASD outcomes using two longitudinal birth cohorts (N=308 mothers, 280 children) designed to examine effects of prenatal alcohol exposure on development. Participants were genotyped via MEGAex array to capture common and rare variants. Rare variants were overrepresented in our SACC cohorts, with numerous polymorphisms being monomorphic in other reference populations (e.g., ∼30,000 and ∼ 221,000 variants in gnomAD European and Asian populations, respectively). The cohorts showed global African (51 %; Bantu and San); European (26 %; Northern/Western); South Asian (18 %); and East Asian (5 %; largely Southern regions) ancestries. The cohorts exhibited high rates of homozygosity (6 %), with regions of homozygosity harboring more deleterious variants when lying within African local-ancestry genomic segments. Both maternal and child ancestry profiles were associated with higher FASD risk, and maternal and child ancestry-by-prenatal alcohol exposure interaction effects were seen on child cognition. Our findings indicate that the SACC population may be a valuable asset to identify novel disease-associated genetic loci for FASD and other diseases.

Abstract
It is estimated that up to 1 in 20 people in the United States may have a fetal alcohol spectrum disorder (FASD), or the array of physical, cognitive, emotional, and social disorders caused by exposure to alcohol during prenatal development (May et al., JAMA 319:474-82, 2018). While this condition is present in a broad range of individuals and families, it has not previously been examined in the military community, where cultural factors including an increased prevalence of alcohol misuse may pose a unique set of challenges (Health.mil, Alcohol misuse, 2024).The Uniformed Services University of the Health Sciences (USUHS), in conjunction with FASD United, hosted the second annual Workshop on Fetal Alcohol Spectrum Disorders Prevention and Clinical Guidelines Research on 20 September 2023 in Washington, DC. Organized as part of a four-year, federally-funded health services research initiative on FASD in the U.S. Department of Defense (DoD) Military Health System (MHS), the workshop provided a forum for exploring the initiative's focus and progress; examining current knowledge and practice in the research and clinical spheres; and identifying potential strategies to further improve prevention, screening, diagnosis, interventions, and family support. Building off of the 2022 workshop that covered the state of the science surrounding prenatal alcohol exposure and FASD, the 2023 focused primarily on FASD and efforts aimed at identification and management (Koehlmoos et al., BMC Proc 17 Suppl 12:19, 2023). One hundred and thirty attendees from academia, healthcare, federal agencies, and patient advocacy organizations gathered to share research findings; learn from lived experiences; and discuss initiatives to advance research, screening, and services for at-risk pregnant women as well as families and caregivers supporting individuals with FASD.

Abstract
Nutritional status during pregnancy can impact fetal development, yet less is known about how alcohol may interact with nutritional status to influence infant outcomes. Pregnant women (n=196) completed 2, 24-hour dietary recalls and provided a venous blood sample to be analyzed for liver enzymes (GGT -gamma-glutamyl transferase; ALT -alanine transaminase; and AST -aspartate transferase), iron, ferritin, and zinc concentrations. Infants were assessed at 6 weeks of age. Women who consumed alcohol had significantly higher ferritin levels compared to non-drinkers (51.8 vs. 34.2). While 44% of women had ferritin <30 ug/L (an indicator of iron deficiency), and 24% of women were low in serum iron, and 72% were low in serum zinc. All six drinking measures for 1st trimester and previous week were significantly correlated with GGT and AST levels while 4 out of 6 alcohol measures were associated with levels of ALT and ferritin. At six weeks of age, nearly all physical measures differentiated infants with alcohol exposure from infants without exposure. Controlling for six covariates, maternal ferritin was significantly and inversely associated with infant head circumference (OFC) centile among infants with alcohol exposure. GGT was inversely associated with infant height and weight centile among unexposed infants. Seventy-four percent (74%) of mothers who consumed alcohol were found to be low in serum zinc, yet higher maternal zinc was associated with more dysmorphology. This may indicate that higher zinc status is not protecting the fetus from the teratogenic effects of alcohol. Prenatal alcohol exposure, ferritin, and zinc status influence infant growth and neurodevelopment.

Influence of childhood trauma and traumatic stress on a woman's risk of having a child with a fetal alcohol spectrum disorder. ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2024; 48:1176-1188. [PMID: 38702143 PMCID: PMC11178454 DOI: 10.1111/acer.15334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 03/22/2024] [Accepted: 04/07/2024] [Indexed: 05/06/2024]
Abstract
BACKGROUND Maternal risk factors for having a child diagnosed on the fetal alcohol spectrum disorders (FASD) continuum are complex and include not only the quantity, frequency, and timing of alcohol use but also a woman's physical stature, socio-economic status, and pregnancy-related factors. Exposure to trauma may predispose women to a range of physiological and mental disorders. A woman's mental and physical health may in turn influence her probability of having a child with FASD. This study investigated the role of maternal childhood trauma and lifetime traumatic stress on prenatal alcohol consumption and on the risk of having a child with FASD. METHODS A nested, case-control study was conducted for maternal risk assessment. Study participants were mothers of first-grade learners from five rural communities in the Western Cape Province of South Africa who were assessed for FASD. Face-to-face surveys were conducted, which included mental health and trauma assessment questionnaires. RESULTS In logistic regression analyses, higher maternal childhood trauma scores were associated with an increased likelihood of having a child diagnosed with FASD, although the increase in risk was modest (OR = 1.014, p = 0.015). In addition, structural equation modeling investigated relationships between maternal drinking, childhood trauma, traumatic stress, and a child's FASD diagnosis. Traumatic stress and drinking during pregnancy, but not lifetime alcohol use, were associated with maternal childhood trauma. Lifetime alcohol use influenced drinking during pregnancy, which in turn was significantly associated with having a child diagnosed on the continuum of FASD. CONCLUSION No direct influence of maternal childhood trauma on FASD diagnosis could be demonstrated. However, maternal trauma may indirectly contribute to the risk of having a child diagnosed with FASD.

ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2024; 48:867-879. [PMID: 38548386 DOI: 10.1111/acer.15306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 03/07/2024] [Accepted: 03/07/2024] [Indexed: 05/07/2024]
Abstract
BACKGROUND South Africa has the highest reported prevalence of fetal alcohol spectrum disorders (FASD) globally. The most recent study reported a weighted, estimated FASD prevalence of 310 per 1000 in a community in the Western Cape Province. Because there is as yet no reliable estimate of the national burden of FASD in South Africa, further epidemiological studies are needed in diverse settings. This paper reports on a multiyear, multisite FASD epidemiological study that took place from 2015 to 2022 at eight study sites in four provinces. METHODS The cross-sectional epidemiological study used an active case-ascertainment method, specifically in primary schools. All children were recruited when they were enrolled in Grade 1 at a participating school. All consented participants progressed through a tiered-screening recruitment and diagnostic process. RESULTS Overall, 3033 children were included in the study. A total of 3001 children were screened for FASD in the first tier, with 1086 progressing to the second and 495 to the third tier. Of the 495 children referred, 475 were discussed during the final case conference. A total of 309 participants were diagnosed with FAS across the eight study sites. The highest reported prevalence was in the Northern Cape Province, with a rate of 199.3/1000 (95% CI, 147.6-251) using all eligible participants as the denominator. The lowest prevalence was in the Eastern Cape Province, with a rate of 57.4/1000 (95% CI, 36.5-78.3). The pooled FAS prevalence for the eight study sites was 80.2/1000 (95% CI, 70.4-89.9). CONCLUSIONS As with previous studies, we found a concerningly high prevalence of FASD in South Africa. Given the scope of the problem it should be a high priority for health and welfare services to address.

Abstract
OBJECTIVE The diagnoses included within the umbrella term fetal alcohol spectrum disorders (FASD), are based on the documentation of prenatal alcohol exposure (PAE), growth deficits and a pattern of dysmorphic physical features and neurobehavioral impairments. Although 3 key facial features (short palpebral fissures, a smooth philtrum and a thin vermilion of the upper lip) are the only dysmorphic features taken into account for the diagnosis of Fetal Alcohol Syndrome (FAS) or partial FAS (pFAS), several other features are commonly seen in individuals with these diagnoses. The goals of our study were to determine if some of these secondary physical features also occur more frequently in children with alcohol-related neurodevelopmental disorder (ARND) relative to controls, and if a cluster of these features combined in a dysmorphology score could be used to identify those negatively impacted by PAE but who do not have the cardinal physical features that led to a diagnosis of FAS or pFAS. METHODS Among 2681 children recruited for the Collaboration on Fetal Alcohol Spectrum Disorders Prevalence (CoFASP) study, 1726 had an FASD or sufficient evidence of PAE having occurred or not in their pregnancy. Children were then categorized into groups using the modified Hoyme diagnostic criteria (FAS (n = 24), pFAS (n = 99) and ARND (n = 87), and No FASD (n = 1516), including those with No FASD and a history of PAE (No FASD/PAE, n = 498) and those with No FASD and no history of PAE (No FASD/No PAE, n = 1018). The frequencies of 26 secondary dysmorphic features were compared among these groups, both individually and combined in non-weighted and weighted dysmorphic scores. Correlations of the total dysmorphic scores with an index of overall cognitive ability were also compared by group status. RESULTS Several of these features were significantly more frequent in children with FAS than in those with No FASD diagnosis with or without PAE but not in comparison to those with ARND. The number of features was also significantly higher in the FAS group as compared to all other groups for both weighted and unweighted dysmorphology scores but were not higher in the group with ARND when compared to the groups with No FASD either in the presence or absence of PAE. Although not diagnostic, higher total dysmorphology scores were predictive of lower general cognitive abilities in the group with ARND, suggesting severity of alcohol-related dysmorphology is predictive of severity of alcohol-related neurobehavioral impairment. CONCLUSION Secondary physical features were not more frequent in children with ARND compared to children without an FASD diagnosis but were a marker for lower cognitive function. The use of secondary physical features to support a diagnosis of ARND was not supported in this sample.

Abstract
BACKGROUND A variety of maternal risk factors for fetal alcohol spectrum disorders (FASD) have been described in the literature. Here, we conducted a multivariate analysis of a large array of potential distal influences on FASD risk. METHODS Interviews were conducted with 2515 mothers of first-grade students whose children were evaluated to assess risk for FASD. Topics included: physical/medical status, childbearing history, demographics, mental health, domestic violence, and trauma. Regression modeling utilized usual level of alcohol consumption by trimester and six selected distal variables (maternal head circumference, body mass index, age at pregnancy, gravidity, marital status, and formal years of education) to differentiate children with FASD from control children. RESULTS Despite individual variation in distal maternal risk factors among and within the mothers of children with each of the common diagnoses of FASD, patterns emerged that differentiated risk among mothers of children with FASD from mothers whose children were developing typically. Case-control comparisons indicate that mothers of children with FASD were significantly smaller physically, had higher gravidity and parity, and experienced more miscarriages and stillbirths, were less likely to be married, reported later pregnancy recognition, more depression, and lower formal educational achievement. They were also less engaged with a formal religion, were less happy, suffered more childhood trauma and interpersonal violence, were more likely to drink alone or with her partner, and drank to deal with anxiety, tension, and to be part of a group. Regression analysis showed that the predictor variables explain 57.5% of the variance in fetal alcohol syndrome (FAS) diagnoses, 30.1% of partial FAS (PFAS) diagnoses, and 46.4% of alcohol-related neurodevelopmental disorder (ARND) diagnoses in children with FASD compared to controls. While the proximal variables explained most of the diagnostic variance, six distal variables explained 16.7% (1 /6 ) of the variance in FAS diagnoses, 13.9% (1 /7 ) of PFAS, and 12.1% (1 /8 ) of ARND. CONCLUSIONS Differences in distal FASD risks were identified. Complex models to quantify risk for FASD hold promise for guiding prevention/intervention.

Abstract
BACKGROUND Early life factors, including parental sociodemographic characteristics, pregnancy exposures, and physical and neurodevelopmental features measured in infancy are associated with fetal alcohol spectrum disorders (FASD). The objective of this study was to evaluate the performance of a classifier model for diagnosing FASD in preschool-aged children from pregnancy and infancy-related characteristics. METHODS We analyzed a prospective pregnancy cohort in Western Ukraine enrolled between 2008 and 2014. Maternal and paternal sociodemographic factors, maternal prenatal alcohol use and smoking behaviors, reproductive characteristics, birth outcomes, infant alcohol-related dysmorphic and physical features, and infant neurodevelopmental outcomes were used to predict FASD. Data were split into separate training (80%: n = 245) and test (20%: n = 58; 11 FASD, 47 no FASD) datasets. Training data were balanced using data augmentation through a synthetic minority oversampling technique. Four classifier models (random forest, extreme gradient boosting [XGBoost], logistic regression [full model] and backward stepwise logistic regression) were evaluated for accuracy, sensitivity, and specificity in the hold-out sample. RESULTS Of 306 children evaluated for FASD, 61 had a diagnosis. Random forest models had the highest sensitivity (0.54), with accuracy of 0.86 (95% CI: 0.74, 0.94) in hold-out data. Boosted gradient models performed similarly, however, sensitivity was less than 50%. The full logistic regression model performed poorly (sensitivity = 0.18 and accuracy = 0.65), while stepwise logistic regression performed similarly to the boosted gradient model but with lower specificity. In a hold-out sample, the best performing algorithm correctly classified six of 11 children with FASD, and 44 of 47 children without FASD. CONCLUSIONS As early identification and treatment optimize outcomes of children with FASD, classifier models from early life characteristics show promise in predicting FASD. Models may be improved through the inclusion of physiologic markers of prenatal alcohol exposure and should be tested in different samples.

Abstract
BACKGROUND Pregnant women participated in multifaceted case management (MCM) to prevent Fetal Alcohol Spectrum Disorders (FASD). METHODS Women recruited from antenatal clinics for a longitudinal child development study were screened for alcohol use. Forty-four pregnant women were defined as high-risk drinkers on the Alcohol Use Disorder Identification Test (AUDIT) by an AUDIT score ≥8 and participated in 18 months of MCM to facilitate reduction or cessation of alcohol consumption. Forty-one women completed MCM. Fifty-five equally high-risk women who received standard antenatal care comprised the comparison/control group. Development in offspring was evaluated by a blinded interdisciplinary team of examiners through 5 years of age. RESULTS At five years of age, more children (34%) of MCM participating women did not meet the criteria for FASD vs. non-MCM offspring (22%). Furthermore, a statistically significant (p = .01) lower proportion of MCM offspring (24%) was diagnosed with fetal alcohol syndrome (FAS) compared to controls (49%). Children of MCM participants had significantly (p < .05) better physical outcomes: lower total dysmorphology scores, larger head circumferences, longer palpebral fissures, and higher midfacial measurements. Neurodevelopment results showed mixed outcomes. While Bayley developmental scores indicated that MCM offspring were performing significantly worse on most domains through 18 months, group scores equalized and were not significantly different on Kaufman Assessment Battery neurobehavioral measures by five years. Regression analyses indicated that offspring of women who received standard antenatal care were associated with significantly more negative outcomes than MCM offspring: a diagnosis of FAS (OR = 3.2; 95% CI: 1.093-9.081), microcephaly (OR = 5.3; 95% CI: 2.1-13.5), head circumference ≤10th centile (OR = 4.3; 95%CI: 1.8-10.4), and short palpebral fissures (OR = 2.5; 95% CI: 1.0-5.8). CONCLUSION At age five, proportionally fewer children of MCM participants qualified for a diagnosis of FAS, and proportionally more had physical outcomes indicating better prenatal brain development. Neurobehavioral indicators were not significantly different from controls by age five.KEY MESSAGESMultifaceted Case Management (MCM) was designed and employed for 18 months during the prenatal and immediate postpartum period to successfully meet multiple needs of women who had proven to be very high risk for birthing children with fetal alcohol spectrum disorders (FASD).Offspring of the women who participated in MCM were followed up through age five years and were found to have significantly better physical outcomes on multiple variables associated with fetal alcohol syndrome (FAS) and FASD, such as larger head circumferences and fewer minor anomalies, than those children born to equally at-risk women not receiving MCM.Fewer children of women receiving MCM were diagnosed with FASD than the offspring of equally-at-risk controls, and significantly (p = .01) fewer MCM offspring had FAS, the most severe FASD diagnosis.

Maternal and paternal risk factors for fetal alcohol spectrum disorders: Alcohol and other drug use as proximal influences. ALCOHOL, CLINICAL & EXPERIMENTAL RESEARCH 2023; 47:2090-2109. [PMID: 38226752 PMCID: PMC10792253 DOI: 10.1111/acer.15193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 08/16/2023] [Accepted: 09/11/2023] [Indexed: 01/17/2024]
Abstract
OBJECTIVE To explore and analyze the significance of proximal influences of maternal and paternal traits associated with bearing a child with a fetal alcohol spectrum disorder (FASD). METHODS Aggregated, maternal interview-collected data (N = 2515) concerning alcohol, tobacco, and other drug use were examined to determine risk for FASD from seven cross-sectional samples of mothers of first-grade students who were evaluated for a possible diagnosis of FASD. RESULTS Mothers of children with fetal alcohol syndrome (FAS) reported the highest alcohol use throughout pregnancy, proportion of binge drinking, drinks per drinking day (DDD), drinking days per week, and total drinks per week. Mothers of children with FAS also consumed significantly more alcohol than mothers of children with partial FAS (PFAS), alcohol-related neurodevelopmental disorder (ARND), or typically developing controls. Mothers of children with PFAS and ARND reported similar drinking patterns, which exposed fetuses to 3-4 times more alcohol than mothers of controls, but the PFAS group was more likely than the ARND group to abstain in latter trimesters. Fathers of all children were predominantly drinkers (70%-85%), but more fathers of children with FASD binged heavily on more days than fathers of controls. Compared to the few mothers of controls who used alcohol during pregnancy, the ARND group binge drank more (3+ DDD) throughout pregnancy and drank more DDD before pregnancy and first trimester. Regression analysis, controlling for tobacco use, indicated that mothers who reported drinking <1 DDD were significantly more likely than abstainers to bear a child with FASD (OR = 2.75) as were those reporting higher levels such as 5-5.9 DDD (OR = 32.99). Exclusive, first-trimester maternal drinking increased risk for FASD five times over that of abstinence (p < 0.001, OR = 5.05, 95% CI: 3.88-6.58), first- and second-trimester drinking by 12.4 times, and drinking all trimesters by 16 times (p < 0.001, OR = 15.69, 95% CI: 11.92-20.64). Paternal drinking during and prior to pregnancy, without adjustment, increased the likelihood of FASD significantly (OR = 1.06 and 1.11, respectively), but the significance of both relationships disappeared when maternal alcohol and tobacco use were controlled. CONCLUSIONS Differences in FASD risk emerged from the examination of multiple proximal variables of maternal alcohol and tobacco use, reflecting increased FASD risk at greater levels of maternal alcohol consumption.

Maternal dietary intake among alcohol-exposed pregnancies is linked to early infant physical outcomes in South Africa. Reprod Toxicol 2023; 121:108467. [PMID: 37678653 PMCID: PMC11187711 DOI: 10.1016/j.reprotox.2023.108467] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 08/10/2023] [Accepted: 08/29/2023] [Indexed: 09/09/2023]
Abstract
Maternal dietary intake is likely a contributing factor to fetal alcohol spectrum disorders (FASD). Two, 24-hour dietary recalls were completed by pregnant women (n = 196) in South African communities with high rates of FASD. More than 50% of all women in this study were below the Estimated Average Requirement (EAR) for pregnancy for vitamins A, C, D, E, riboflavin, vitamin B6, folate, calcium, magnesium, iron, and zinc. More than 90% of mothers were below the Recommended Dietary Allowance (RDA) or Adequate Intake (AI) for pregnancy on vitamin A, K, D, E, choline, calcium, magnesium, zinc, and potassium. More than 80% were below RDA/AI for pantothenic acid, vitamin B6, and folate. Women who consumed alcohol reported significantly lower intake of calcium and three saturated fatty acids and significantly higher intake of two monounsaturated fatty acids. On average, infants were < 40th centile on length, weight, and head circumference at 6 weeks old, regardless of alcohol exposure. Twenty nutrients correlated with at least one measure of 1st trimester drinking (drinks per drinking day, number of drinking days per week, and/or total drinks per week). Nutrients included four saturated fatty acids, eight amino acids, calcium, B-complex vitamins, choline, and betaine. Calcium correlated with all three drinking measures. Further analyses revealed seven nutrients were associated with infant length, weight, and/or head circumference among unexposed infants, and 12 nutrients were associated among infants with prenatal alcohol exposure. Inadequate maternal dietary intake, with alcohol exposure, may increase risk for poor infant growth and likelihood of FASD in this population.

The burden, prevention and care of infants and children with congenital anomalies in sub-Saharan Africa: A scoping review. PLOS GLOBAL PUBLIC HEALTH 2023; 3:e0001850. [PMID: 37379291 PMCID: PMC10306220 DOI: 10.1371/journal.pgph.0001850] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 03/17/2023] [Indexed: 06/30/2023]
Abstract
The aim of this scoping review was to determine the scope, objectives and methodology of contemporary published research on congenital anomalies (CAs) in sub-Saharan Africa (SSA), to inform activities of the newly established sub-Saharan African Congenital Anomaly Network (sSCAN). MEDLINE was searched for CA-related articles published between January 2016 and June 2021. Articles were classified into four main areas (public health burden, surveillance, prevention, care) and their objectives and methodologies summarized. Of the 532 articles identified, 255 were included. The articles originated from 22 of the 49 SSA countries, with four countries contributing 60% of the articles: Nigeria (22.0%), Ethiopia (14.1%), Uganda (11.7%) and South Africa (11.7%). Only 5.5% of studies involved multiple countries within the region. Most articles included CA as their primary focus (85%), investigated a single CA (88%), focused on CA burden (56.9%) and care (54.1%), with less coverage of surveillance (3.5%) and prevention (13.3%). The most common study designs were case studies/case series (26.6%), followed by cross-sectional surveys (17.6%), retrospective record reviews (17.3%), and cohort studies (17.2%). Studies were mainly derived from single hospitals (60.4%), with only 9% being population-based studies. Most data were obtained from retrospective review of clinical records (56.1%) or via caregiver interviews (34.9%). Few papers included stillbirths (7.5%), prenatally diagnosed CAs (3.5%) or terminations of pregnancy for CA (2.4%).This first-of-a-kind-scoping review on CA in SSA demonstrated an increasing level of awareness and recognition among researchers in SSA of the contribution of CAs to under-5 mortality and morbidity in the region. The review also highlighted the need to address diagnosis, prevention, surveillance and care to meet Sustainable Development Goals 3.2 and 3.8. The SSA sub-region faces unique challenges, including fragmentation of efforts that we hope to surmount through sSCAN via a multidisciplinary and multi-stakeholder approach.

Abstract
Background The fetal alcohol spectrum disorder is a group of developmental disorders caused by maternal alcohol consumption. Patients with fetal alcohol syndrome show abnormal orofacial features. This review presents an overview over the facial, oral, dental or orthodontic findings and diagnostic tools concerning these features. Methods For this systematic review Cochrane, Medline and Embase databases were considered and the review was performed according to the PRISMA checklist. Two independent reviewers evaluated all studies and recorded results in a summary of findings table. Risk of bias was analyzed via Quadas-2 checklist. Results 61 studies were eligible for inclusion. All included studies were clinical studies. Methods and results of the studies were not comparable, guidelines or methods for the detection of FASD varied across studies. Facial features most often measured or found as distinguishing parameter were: palpebral fissure length, interpupillary or innercanthal distance, philtrum, upper lip, midfacial hypoplasia or head circumference. Conclusions This review shows that to date a multitude of heterogeneous guidelines exists for the diagnosis of FASD. Uniform, objective diagnostic criteria and parameters for the orofacial region in FASD diagnosis are needed. A bio database with values and parameters for different ethnicities and age groups should be made available for diagnosis.

Abstract
BACKGROUND This early intervention study investigated the effectiveness of a relationship-based, developmental enhancement process for children who were prenatally exposed to alcohol in the South African context. METHODS Groups were created according to the child's level of risk for alcohol-related developmental issues based on each mother's alcohol use during pregnancy as assessed using the Alcohol Use Disorders Identification Test (AUDIT). Primary caregiver/child dyads were the focus of the intervention and child development was monitored by the Ages and Stages Questionnaire (ASQ). Eighteen caregiver/child dyads were in the heavily alcohol-exposed group, and 20 caregiver/child dyads were in the no or light alcohol-exposure group. The Home Observation Measurement of the Environment (HOME) was measured pre and post intervention. RESULTS The results indicated significant improvements in the home environment (p < .001) post-intervention for the entire cohort. For the total HOME score, there was a statistically significant main effect for time (pre- vs post-test), F(1, 36)= 65.205, p < .001, partial η2 = .64. with 99% confidence limits from .35 to .78. The offspring and parents from both the heavy alcohol exposure group and the no/low alcohol exposure group benefitted from the intervention over the duration of the intervention. Of the HOME domains affected, responsivity was the most improved in the households. The children's scores on the ASQ varied substantially over the months of the intervention, and the offspring of the heavy exposure group often performed significantly worse than the no/low exposure group. Nevertheless, further analysis revealed that children with the lowest performance at baseline improved their performance on most ASQ domains throughout the intervention and performed significantly better on all ASQ domains over time and at completion of the intervention. CONCLUSIONS This relationship-based, early intervention program for children resulted in benefits to all of the children over time.

Abstract
BACKGROUND Infants with fetal alcohol syndrome exhibit a range of developmental anomalies, many related to the heart (e.g., decreased heart rate variability). However, the baseline heart rate in this population remains unclear. We hypothesized that the age at which heart rate was measured or the age during exposure to alcohol affects the baseline heart rate. METHODS First, we conducted a systemic review to determine the published heart rate of infants with prenatal alcohol exposure (PAE). Exclusion criteria included potentially confounding factors, including the commonly associated phenotypes of small for gestational age and premature birth. Risk of bias was evaluated based on case study limitations, and data were compared with established heart rate norms. Then, we evaluated the precise age at heart rate measurement using existing datasets from the Collaborative Initiative on Fetal Alcohol Spectrum Disorders and the Maternal Lifestyle Study. RESULTS Based on the weighted means of six studies, the baseline heart rate was 4.6 bpm higher in infants with PAE (n = 253) than in control infants (n = 152). Using the individual patient data, baseline heart rates were similar between age-matched infants with PAE and control infants who were born full-term and showed no signs of growth restriction (ANOVA, p > .05; n = 49-124 infants per age and exposure). CONCLUSIONS A systematic literature review suggested that heart rate is elevated in infants with PAE, but these findings are limited by the number of studies and how few studies included control infants. The analysis of individual patient data indicates that infants with PAE have normal baseline heart rates. This knowledge may help clinicians detect changes in cardiac function in infants with PAE.

Abstract
Prenatal alcohol exposure can produce offspring growth deficits and is a leading cause of neurodevelopmental disability. We used untargeted metabolomics to generate mechanistic insight into how alcohol impairs fetal development. In the Western Cape Province of South Africa, 52 women between gestational weeks 5-36 (mean 18.5 ± 6.5) were recruited, and they provided a finger-prick fasting bloodspot that underwent mass spectrometry. Metabolomic data were analyzed using partial least squares-discriminant analyses (PLS-DA) to identify metabolites that correlated with alcohol exposure and infant birth outcomes. Women who consumed alcohol in the past seven days were distinguished by a metabolite profile that included reduced sphingomyelins, cholesterol, and pregnenolones, and elevated fatty acids, acyl and amino acyl carnitines, and androsterones. Using PLS-DA, 25 of the top 30 metabolites differentiating maternal groups were reduced by alcohol with medium-chain free fatty acids and oxidized sugar derivatives having the greatest influence. A separate ortho-PLS-DA analysis identified a common set of 13 metabolites that were associated with infant length, weight, and head circumference. These included monoacylglycerols, glycerol-3-phosphate, and unidentified metabolites, and most of their associations were negative, implying they represent processes having adverse consequences for fetal development.

Association of alcohol consumption with abortion among ever-married reproductive age women in Ethiopia: A multilevel analysis. Front Glob Womens Health 2022; 3:1028166. [PMID: 36589150 PMCID: PMC9795045 DOI: 10.3389/fgwh.2022.1028166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Accepted: 11/10/2022] [Indexed: 12/23/2022] Open
Abstract
Background A miscarriage or a spontaneous loss of a pregnancy that occurs before the 20th week is an abortion. Even though numerous recommendations state that pregnant women should abstain from alcohol at all stages of pregnancy, alcohol intake among pregnant women is common. However, there are few papers addressing the effect of alcohol use on miscarriage using nationally representative data. Moreover, the association of alcohol use with abortion and its mechanisms is not well studied in the Ethiopian region. Therefore, the objective of the current study was to estimate the association of alcohol use with abortion rates among reproductive age (15-49) women in Ethiopia. Methods Using the most recent findings of the Ethiopian Demographic and Health Survey (EDHS), secondary data analysis was performed among pregnant women in Ethiopia. A total of 11,396 women between the ages of 15 and 49 years who were of reproductive age were included in the research. To characterize the study population, descriptive statistics were used. The variability was considered using the multilevel binary logistic regression model. A multilevel binary logistic model was used to determine the effect of alcohol intake on abortion while controlling for potential confounders. In the multivariable analysis, variables with a P-value of less than 0.05 were considered statistically significant for the response variable. Results The proportion of women who had an abortion was 10.46% with a 95% CI of 9.92-11.03. In the final model of the multilevel analysis, age group [adjusted odds ratio (AOR) = 6.13; 95% CI: 3.86-9.73], education level (AOR = 1.29; 95 and CI: 1.10-1.51), alcohol consumption (AOR = 1.38; 95% CI: 1.18-1.61), age at first sex (AOR = 1.20; 95% CI: 1.03-1.39), media exposure (AOR = 1.28, CI: 1.10-1.48), contraceptive use (AOR = 1.34, CI: 1.16-1.56), and occupation of respondent (AOR = 1.21, CI: 1.06-1.38) were identified to be significant determinants of abortion in Ethiopia. Conclusion Sexual and reproductive health education and family planning programs should target older women in the reproductive age group, women with primary educational status, working women, and those who initiated sexual intercourse at a younger age considering it could reduce abortion and unintended pregnancy. Furthermore, as part of sexual and reproductive health education, the adverse effect of alcohol consumption on abortion should be emphasized.

Abstract
We have previously demonstrated prenatal alcohol exposure (PAE)-related alterations in maternal and infant iron homeostasis. Given that early iron deficiency and PAE both lead to growth restriction and deficits in recognition memory and processing speed, we hypothesized that PAE-related iron homeostasis alterations may mediate and/or moderate effects of PAE on growth and neurobehavior. We examined this hypothesis in a prenatally recruited, prospective longitudinal birth cohort [87 mother-infant pairs with heavy prenatal alcohol exposure (mean = 7.2 drinks/occasion on 1.4 days/week); 71 controls], with serial growth measures and infant neurobehavioral assessments. PAE was related to growth restriction at 2 weeks and 5 years, and, in infancy, poorer visual recognition memory, slower processing speed, lower complexity of symbolic play, and higher emotionality and shyness on a parental report temperament scale. Lower maternal hemoglobin-to-log(ferritin) ratio, which we have shown to be associated with PAE, appeared to exacerbate PAE-related 2-week head circumference reductions, and elevated maternal ferritin, which we have shown to be associated with PAE, appeared to exacerbate PAE-related visual recognition memory deficits. In causal inference analyses, PAE-related elevations in maternal ferritin and hemoglobin:log(ferritin) appeared to statistically mediate 22.6-82.3% of PAE-related growth restriction. These findings support potential mechanistic roles of iron homeostasis alterations in fetal alcohol spectrum disorders (FASD).

The prevalence of fetal alcohol spectrum disorders in rural communities in South Africa: A third regional sample of child characteristics and maternal risk factors. Alcohol Clin Exp Res 2022; 46:1819-1836.

Abstract
BACKGROUND This study is the ninth cross-sectional community study of fetal alcohol spectrum disorders (FASD) conducted by the multidisciplinary Fetal Alcohol Syndrome Epidemiology Research team in the Western Cape Province of South Africa. It is the third comprehensive study of FASD in a rural, agricultural region of South Africa. METHODS Population-based, active case ascertainment methods were employed among a school-based cohort to assess child physical and neurobehavioral traits, and maternal risk factor interviews were conducted to identify all children with FASD to determine its prevalence. RESULTS Consent was obtained for 76.7% of 1158 children attending first grade in the region's public schools. Case-control results are presented for 95 with fetal alcohol syndrome (FAS), 64 with partial fetal alcohol syndrome (PFAS), 77 with alcohol-related neurodevelopmental disorder (ARND), 2 with alcohol-related birth defects (ARBD), and 213 randomly-selected controls. Four techniques estimating FASD prevalence from in-person examinations and testing yielded a range of total FASD prevalence of 206-366 per 1000. The final weighted, estimated prevalence of FAS was 104.5 per 1000, PFAS was 77.7 per 1000, ARND was 125.2 per 1000, and total FASD prevalence was 310 per 1000 (95% CI = 283.4-336.7). Expressed as a percentage, 31% had FASD. Although the rate of total FASD remained steady over 9 years, the proportion of children within the FASD group has changed significantly: FAS trended down and ARND trended up. A detailed evaluation is presented of the specific child physical and neurobehavioral traits integral to assessing the full continuum of FASD. The diagnosis of a child with FASD was significantly associated with maternal proximal risk factors such as: co-morbid prenatal use of alcohol and tobacco (OR = 19.1); maternal drinking of two (OR = 5.9), three (OR = 5.9), four (OR = 38.3), or more alcoholic drinks per drinking day; and drinking in the first trimester (OR = 8.4), first and second trimesters (OR = 17.7), or throughout pregnancy (OR = 18.6). Distal maternal risk factors included the following: slight or small physical status (height, weight, and head circumference), lower BMI, less formal education, late recognition of pregnancy, and higher gravidity, parity, and older age during the index pregnancy. CONCLUSION The prevalence of FASD remained a significant problem in this region, but the severity of physical traits and anomalies within the continuum of FASD is trending downwards.

Abstract
Prenatal alcohol exposure (PAE) has been linked to atypical brain and cognitive development, including poor academic performance in reading. This study utilized functional magnetic resonance imaging and diffusion tensor imaging to characterize functional and structural mechanisms mediating reading deficits in 26 adolescents with PAE-related facial dysmorphology (fetal alcohol syndrome (FAS)/partial FAS (PFAS)), 29 heavily-exposed (HE) non-syndromal adolescents, in comparison with 19 typically developing controls. The FAS/PFAS and HE groups were balanced in terms of levels of PAE and reading (dis)ability. While neural alterations in the posterior association cortices were evident in both PAE groups, distinctive neural correlates of reading (dis)abilities were observed between adolescents with and without facial dysmorphology. Specifically, compared to the HE and control groups, the syndromal adolescents showed greater activation in the right precentral gyrus during phonological processing and rightward lateralization in an important reading-related tract (inferior longitudinal fasciculus, ILF), suggesting an atypical reliance on the right hemisphere. By contrast, in the HE, better reading skills were positively correlated with neural activation in the left angular gyrus and white matter organization of the left ILF, although the brain function-behavior relation was weaker than among the controls, suggesting less efficient function of the typical reading network. Our findings provide converging evidence at both the neural functional and structural levels for distinctive brain mechanisms underlying atypical reading and phonological processing in PAE adolescents with and without facial dysmorphology.

Abstract
Maternal weight was inversely related with infant dysmorphology score. The rate of change was similar among all infants regardless of maternal weight. Maternal weight may be protective but does not eliminate adverse effects of alcohol. Regardless of maternal weight during pregnancy, alcohol remains a teratogen.
Background Mothers of children with fetal alcohol spectrum disorders tend to have lower weight compared to other mothers. Yet how alcohol and maternal weight may predispose infants to poorer physical growth and neurodevelopmental trajectories is relatively unexplained. Methods South African mothers (n = 406) were recruited prenatally and their offspring were provided standardized dysmorphology and neurodevelopment examinations at 6 weeks and 9 months of age. Maternal weight was obtained postpartum, and linear mixed modeling determined whether postpartum maternal weight and prenatal alcohol exposure significantly influenced infant growth, dysmorphology, and neurodevelopment within the first year of life. Results Postpartum maternal weight was positively associated with birth length, weight, and head circumference centile, but the rate of growth from birth to nine months was similar among all infants. Maternal weight was inversely associated with dysmorphology. Many infants in this population were performing within the borderline or extremely low range. Higher maternal weight was associated with significantly better cognitive and motor performance at 6 weeks; however, the rate of developmental growth was similar among all infants, regardless of postpartum maternal weight. Conclusion Higher postpartum maternal weight may be a protective factor but does not eliminate the adverse effects of alcohol on infant growth and dysmorphology. Regardless of maternal weight, alcohol remains a powerful teratogen and moderate to high use prenatally can result in adverse infant physical and neurocognitive development.

Abstract
Prenatal alcohol exposure causes neurodevelopmental disability and is associated with a functional iron deficiency in the fetus and neonate, even when the mother consumes an apparently iron-adequate diet. Here, we test whether gestational administration of the clinically relevant iron supplement Fer-In-Sol mitigates alcohol’s adverse impacts upon the fetus. Pregnant Long-Evans rats consumed an iron-adequate diet and received 5 g/kg alcohol by gavage for 7 days in late pregnancy. Concurrently, some mothers received 6 mg/kg oral iron. We measured maternal and fetal weights, hematology, tissue iron content, and oxidative damage on gestational day 20.5. Alcohol caused fetal anemia, decreased fetal body and brain weight, increased hepatic iron content, and modestly elevated hepatic malondialdehyde (p’s < 0.05). Supplemental iron normalized this brain weight reduction in alcohol-exposed males (p = 0.154) but not female littermates (p = 0.031). Iron also reversed the alcohol-induced fetal anemia and normalized both red blood cell numbers and hematocrit (p’s < 0.05). Iron had minimal adverse effects on the mother or fetus. These data show that gestational iron supplementation improves select fetal outcomes in prenatal alcohol exposure (PAE) including brain weight and hematology, suggesting that this may be a clinically feasible approach to improve prenatal iron status and fetal outcomes in alcohol-exposed pregnancies.

Abstract
We compared growth, physical features, and minor anomalies in 131 first-grade children with fetal alcohol spectrum disorders (FASD) to those of a representative comparison group of typically developing children from the same populations (n = 1212). The data were collected from three regional sites in the NIAAA-funded Collaboration on FASD Prevalence (CoFASP). Dysmorphology examinations were performed by a team of expert clinical geneticists, and FASD diagnoses were assigned according to the Revised Institute of Medicine Guidelines, which include assessments of growth, dysmorphology, neurobehavior, and maternal risk interviews. We present detailed data on 32 physical traits, minor anomalies, and a summary dysmorphology score for children within each of the four diagnostic categories in the continuum of FASD. There were few differences in the frequency of FASD diagnoses by race or Hispanic ethnicity. Children with FASD were born to mothers who reported using alcohol, tobacco (28.3%), and other drugs (14.2%) during pregnancy. Controlling for tobacco and other drug use, risk analysis indicated that women with a drinking pattern of 3 drinks per drinking day prior to pregnancy were 10 times more likely (p < 0.001, OR = 9.92, 95% CI: 4.6-21.5) to bear a child with FASD than those who reported abstinence prior to pregnancy.

Externalizing behavior in preschool children in a South African birth cohort: Predictive pathways in a high-risk context. Dev Psychopathol 2022; 35:982-999.

Abstract
Mental health problems often begin in early childhood. However, the associations of various individual and contextual risk factors with mental health in the preschool period are incompletely understood, particularly in low- to middle-income countries (LMICs) where multiple risk factors co-exist. To address this gap, we prospectively followed 981 children in a South African birth cohort, the Drakenstein Child Health Study, assessing pre-and postnatal exposures and risk factors. The predictive value of these factors for child mental health (assessed by the Child Behavior Checklist) was modeled using structural equation modeling. We identified two key pathways to greater externalizing behavior: (1) prenatal exposure to substances (alcohol and smoking) directly predicted increased externalizing behavior (β = 0.24, p < 0.001); this relationship was partially mediated by an aspect of infant temperament (negative emotionality; β = 0.05, p = 0.016); (2) lower socioeconomic status and associated maternal prenatal depression predicted more coercive parenting, which in turn predicted increased externalizing behavior (β = 0.18, p = 0.001). Findings in this high-risk LMIC cohort cohere with research from higher income contexts, and indicate the need to introduce integrated screening and intervention strategies for maternal prenatal substance use and depression, and promoting positive parenting across the preschool period.

Abstract
OBJECTIVE To systematically review and conduct meta-analysis on studies that report the type and prevalence of functional and structural ear abnormalities among children with prenatal alcohol exposure and/or fetal alcohol spectrum disorder (FASD). STUDY DESIGN MEDLINE, PubMed, Embase, Web of Science, PsycINFO, ERIC, CINAHL, and Maternity and Infant Care were searched from 1806 through March 2021. Reference lists of relevant articles were manually searched. Studies reporting on functional and/or structural ear abnormalities among children (<18 years) with prenatal alcohol exposure and/or FASD were eligible. Data extraction and quality assessment were performed by one reviewer and independently checked by another. A random effects meta-analysis was conducted. RESULTS A total of 31 studies met the inclusion criteria and 25 were included in the meta-analyses, representing a total of 843 children with prenatal alcohol exposure and 1653 children with FASD. Functional ear abnormalities with the highest pooled prevalence were chronic serous otitis media (88.5%; 95% CI, 70.4%-99.3%), abnormal auditory filtering (80.1%; 95% CI, 76.5%-84.3%), and unspecified conductive hearing loss (68.0%; 95% CI, 51.9%-82.2%). Structural ear abnormalities with the highest pooled prevalence were microtia (42.9%; 95% CI, 26.8%-59.7%), railroad track ear (16.8%; 95% CI, 8.1%-27.7%), and misplaced ear (12.3%; 95% CI, 7.6%-17.9%). CONCLUSIONS Our findings highlight the importance of examining the ears during assessment for FASD, and the need for public health messaging regarding the harms of prenatal alcohol exposure.

The impact of micronutrient supplementation in alcohol-exposed pregnancies on reaction time responses of preschoolers in Ukraine. Alcohol 2022; 99:49-58. [PMID: 34942330 PMCID: PMC8844237 DOI: 10.1016/j.alcohol.2021.12.002] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 12/03/2021] [Accepted: 12/10/2021] [Indexed: 12/12/2022]
Abstract
The potential of micronutrients to ameliorate the impact of prenatal alcohol exposure (PAE) on attentional regulation skills was explored in a randomized clinical trial conducted in Ukraine. Women who differed in prenatal alcohol use were recruited during pregnancy and assigned to one of three groups [No study-provided supplements, Multivitamin/Mineral Supplement (MVM), or MVM plus Choline]. Their offspring were seen in the preschool period and a reaction time task was administered. Participants were asked to press a response button as quickly as possible as 30 stimuli from the same category (animals) were presented consecutively and then followed by six stimuli from a novel category (vehicles). Number correct, mean latency of the response over trials, and variability in the latency were analyzed separately by sex. During the initial animal trials, boys whose mothers received MVM during pregnancy had more correct responses and reduced response latency compared to boys whose mothers had no MVM treatment. During vehicle trials, maternal choline supplementation was associated with increased response speed in males without a PAE history. Females receiving supplements did not show the same benefits from micronutrient supplementation and were more adversely impacted by prenatal alcohol exposure. Relationships between maternal levels of choline, betaine, and dimethylglycine (DMG) and task performance were also assessed. Although no effects were found for choline after adjusting for multiple comparisons, lower baseline DMG level was associated with greater accuracy and shorter latency of responses in the initial animal trials and shorter latency in the vehicle trials in female preschoolers. Level of betaine in Trimester 3 was associated with reduced variability in the latency of male responses during the animal trials. Maternal micronutrient supplementation in pregnancy appears to improve preschool reaction time performance, but the effects varied as a function of sex and PAE exposure status.

Abstract
The experienced team of researchers, McCarthy, Mukerjee, Fleming, Green, Clayton-Smith, Price, Allely, and Cook describe a well-designed and thoughtful study of the "Prevalence of Fetal Alcohol Spectrum Disorders (FASD) in Greater Manchester, UK." This paper is a contribution to the field, for it represents one of a handful of active case ascertainment (ACA) studies of FASD carried out among school children in Europe. McCarthy et al. report a minimal prevalence of FASD of 1.8% and an estimated rate of 3.4% if probable cases are included.

Abstract
OBJECTIVE Utilize a random sample to estimate the prevalence, child traits, and maternal risk for fetal alcohol spectrum disorders (FASD) in a Southeastern United States county. METHODS From all first-grade students (n = 1073) a simple random sample was drawn, and 32 % (n = 231) were consented. All 231 children were examined for dysmorphology and growth, 84 were tested and rated on neurobehavior, and 72 mothers were interviewed for maternal risk. RESULTS Significant differences (α = .05) between the physical traits of children diagnosed with FASD and the entire sample were height, weight, head circumference, body mass index, and total dysmorphology scores, and all three cardinal features of fetal alcohol syndrome: palpebral fissure length, smooth philtrum, and narrow vermilion. Intellectual function and inhibition were not significantly different between FASD and typically-functioning children, but two executive function measures and one visual/spatial measure approached significance (α = .10). Three behavioral measures were significantly worse for the FASD group: parent-rated problems of communication, daily living, and socialization. Significant maternal risk factors reported were postpartum depression, frequency of drinking, and recovery from problem drinking. The prevalence of FASD was 71.4 per 1,000 or 7.1 %. This rate falls clearly within the prevalence range identified in eight larger samples of other communities in the Collaboration on FASD Prevalence (CoFASP) study in four regions of the United States. CONCLUSION Careful and detailed clinical evaluation of children from small random samples can be useful for estimating the prevalence and traits of FASD in a community.

Abstract
OBJECTIVE To investigate gestational age and growth at birth as predictors of fetal alcohol spectrum disorders (FASD). METHODS The sample analyzed here comprises 737 randomly selected children who were assessed for growth, dysmorphology, and neurobehavior at 7 years of age. Maternal interviews were conducted to ascertain prenatal alcohol exposure and other maternal risk factors. Birth data originated from clinic records and the data at 7 years of age originated from population-based, in-school studies. Binary linear regression assessed the relationship between preterm birth, small for gestational age (SGA), and their combination on the odds of a specific FASD diagnosis or any FASD. RESULTS Among children diagnosed with FASD at 7 years of age (n = 255), a review of birth records indicated that 18.4% were born preterm, 51.4% were SGA, and 5.9% were both preterm and SGA. When compared to non-FASD controls (n = 482), the birth percentages born preterm, SGA, and both preterm and SGA were respectively 12.0%, 27.7%, and 0.5%. Mothers of children with FASD reported more drinking during all trimesters, higher gravidity, lower educational attainment, and older age at pregnancy. After controlling for usual drinks per drinking day in the first trimester, number of trimesters of drinking, maternal education, tobacco use, and maternal age, the odds ratio of an FASD diagnosis by age 7 was significantly associated with SGA (OR = 2.16, 95% CI: 1.35 to 3.45). SGA was also significantly associated with each of the 3 most common specific diagnoses within the FASD continuum: fetal alcohol syndrome (FAS; OR = 3.1), partial FAS (OR = 2.1), and alcohol-related neurodevelopmental disorder (OR = 2.0). CONCLUSION SGA is a robust early indicator for FASD in this random sample of children assessed at 7 years of age.

The frequency of severe Fetal Alcohol Spectrum Disorders in the neonatal period using data from the French hospital discharge database between 2006 and 2013. Drug Alcohol Depend 2021; 225:108748. [PMID: 34058539 DOI: 10.1016/j.drugalcdep.2021.108748] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Revised: 03/26/2021] [Accepted: 03/29/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUNDS At birth, only complete Fetal Alcohol Syndrome (FAS) can be properly diagnosed. However, other Consequences of prenatal Alcohol Exposure (CAE) can also be recorded. Our objective was to describe the frequency of diagnoses highly suggestive of "potential Fetal Alcohol Syndrome Disorder" (pFASD, i.e., FAS and CAE) among hospitalized neonates, during the neonatal period, in France, between 2006 and 2013. METHODS We used the French national hospital discharge database to identify the Q86.0 (FAS) and P04.3 (CAE) ICD-10 codes in hospital stays occurring in the first 28 days of life. FAS, CAE and pFASD rates were estimated per 1000 live births at the national level for the 2009-2013 period. We compared the 2006-2009 and 2010-2013 rates. The pFASD rates were also estimated at the regional level. RESULTS Overall, 3,207 cases of pFASD were diagnosed during the neonatal period (i.e., 0.48 cases per 1000 live births, including 0.07 cases of FAS per 1000). Between 2006-2009 and 2010-2013, pFASD remained stable, despite a moderate decrease in reported FAS (0.08 vs 0.06 cases per 1000, p < 0.001). At the regional level, pFASD rates varied between 0.13 and 1.22 cases per 1000. CONCLUSIONS This study provides the first national estimate of neonatal diagnosis of FAS, and more broadly pFASD, in France. Although our data certainly underestimate the real prevalence of FASD, they provide a minimal estimate of the burden of alcohol use during pregnancy. Observed variations deserve to be analyzed in the light of concomitant prevention and public information campaigns.
