Maternal risk factors for fetal alcohol spectrum disorders: Distal variables.

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.

Multifaceted case management during pregnancy is associated with better child outcomes and less fetal alcohol syndrome.

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.

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.

The prevalence of fetal alcohol spectrum disorders in rural communities in South Africa: A third regional sample of child characteristics and maternal risk factors.

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.

Characteristic physical traits of first-grade children in the United States with fetal alcohol spectrum disorders (FASD) and associated alcohol and drug exposures.

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.

Birth Outcomes in Women Who Have Taken Hydroxycholoroquine During Pregnancy: A Prospective Cohort Study.

OBJECTIVE: Findings from previous small studies have been reassuring regarding the safety of treatment with hydroxychloroquine (HCQ) during pregnancy. In one recent study, it was demonstrated that the frequency of major birth defects was increased in women who had received HCQ at a dose of ≥400 mg/day during pregnancy. This study was undertaken to examine pregnancy outcomes among women following the use of HCQ. METHODS: The study cohort comprised pregnant women who were prospectively enrolled in the MotherToBaby/Organization of Teratology Information Specialists Autoimmune Diseases in Pregnancy Study and were receiving treatment with HCQ. For the control groups, disease-matched women without HCQ exposure and healthy women were randomly selected from the same source, with subject matching using a 1:1 ratio. Data were collected through interviews, medical records, and dysmorphology examinations. Pregnancy outcome measures included the presence or absence of major and minor birth defects, rates of spontaneous abortion, rates of preterm delivery, and infant growth measures. RESULTS: Between 2004 and 2018, 837 pregnant women met the criteria for study inclusion, including 279 women exposed to HCQ during pregnancy and 279 women in each unexposed control group. Sixty pregnant women (7.2%) were lost to follow-up. Among the women with live births, major birth defects occurred as a pregnancy outcome in 20 (8.6%) of 232 women with HCQ exposure in the first trimester, compared to 19 (7.4%) of 256 disease-matched unexposed controls (odds ratio [OR] 1.18, 95% confidence interval [95% CI] 0.61-2.26) and 13 (5.4%) of 239 healthy controls (adjusted OR 0.76, 95% CI 0.28-2.05). Risks did not differ in women who were receiving an HCQ dose of ≥400 mg/day. No pattern of birth defects was identified. There were no differences in the rates of spontaneous abortion or preterm delivery between groups. Occurrence of infant growth deficiencies did not differ in the HCQ-exposed group compared to the disease-matched unexposed control group, except in the infant's head circumference at birth (adjusted OR 1.85, 95% CI 1.07-3.20). CONCLUSION: In this study, there was no evidence of an increased risk of structural birth defects or other adverse outcomes among women receiving HCQ during pregnancy, with the exception of infant head circumference at birth. For pregnant women being treated with HCQ, these findings are reassuring.

Gestational age and birth growth parameters as early predictors of fetal alcohol spectrum disorders.

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.

Estimating the community prevalence, child traits, and maternal risk factors of fetal alcohol spectrum disorders (FASD) from a random sample of school children.

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.

The prevalence, child characteristics, and maternal risk factors for the continuum of fetal alcohol spectrum disorders: A sixth population-based study in the same South African community.

BACKGROUND: Prevalence and characteristics of fetal alcohol spectrum disorders (FASD) have been described previously in this community. METHODS: Active case ascertainment methods were employed in a new cross-sectional study with Revised Institute of Medicine criteria among first grade students (n = 735) via dysmorphology examinations and neurobehavioral assessments. Their mothers were interviewed regarding risk factors. Final diagnoses were assigned via structured case conferences. RESULTS: Children with fetal alcohol syndrome (FAS), partial FAS (PFAS), and alcohol related-neurodevelopmental disorder (ARND) were significantly different from controls on all cardinal variables, multiple dysmorphology traits and neurobehavioral performance. Mothers of children with FASD reported significantly more drinking before and during pregnancy (mothers of children with FAS reported 7.8 (±6.1) drinks per drinking day (DDD) prior to pregnancy and 5.1 (±5.9) after pregnancy recognition). Distal risk variables for a diagnosis on the continuum of FASD were: lower maternal height, weight, and body mass index; higher gravidity; lower education and household income; and later pregnancy recognition. Alcohol and tobacco remain the only commonly used drugs. Women reporting first trimester drinking of two DDD were 13 times more likely (95 % CI:1.3-133.4) to have a child with FASD than non-drinkers; and those who reported drinking throughout pregnancy were 19.4 times more likely (95 % CI:8.2-46.0) to have a child with FASD. CONCLUSION: Seventeen years after the first study in this community, FASD prevalence remains high at 16 %-31 %. The FAS rate may have declined somewhat, but rates of PFAS and ARND seemed to plateau, at a high rate.

Ocular measurements in fetal alcohol spectrum disorders.

Fetal alcohol spectrum disorders (FASD) describe a range of physical, behavioral, and neurologic deficits in individuals exposed to alcohol prenatally. Reduced palpebral fissure length is one of the cardinal facial features of FASD. However, other ocular measurements have not been studied extensively in FASD. Using the Fetal Alcohol Syndrome Epidemiologic Research (FASER) database, we investigated how inner canthal distance (ICD), interpupillary distance (IPD), and outer canthal distance (OCD) centiles differed between FASD and non-FASD individuals. We compared ocular measurement centiles in children with FASD to non-FASD individuals and observed reductions in all three centiles for ICD, IPD, and OCD. However, when our non-FASD children who had various forms of growth deficiency (microcephaly, short-stature, or underweight) were compared to controls, we did not observe a similar reduction in ocular measurements. This suggests that reductions in ocular measurements are a direct effect of alcohol on ocular development independent of its effect on growth parameters, which is consistent with animal models showing a negative effect of alcohol on developing neural crest cells. Interpupillary distance centile appeared to be the most significantly reduced ocular measure we evaluated, suggesting it may be a useful measure to be considered in the diagnosis of FASD.

Fetal Alcohol Spectrum Disorders in a Rocky Mountain Region City: Child Characteristics, Maternal Risk Traits, and Prevalence.

OBJECTIVE: To document prevalence and traits of children with fetal alcohol spectrum disorders (FASD) and maternal risk factors in a Rocky Mountain city. METHODS: Variations on active case ascertainment methods were used in 2 first-grade cohorts in all city schools. The consent rate was 59.2%. Children were assessed for physical growth, dysmorphology, and neurobehavior and their mothers interviewed. RESULTS: Thirty-eight children were diagnosed with FASD and compared with 278 typically developing controls. Total dysmorphology scores summarized well the key physical indicators of FASD and defined specific diagnostic groups. On average, children with FASD performed significantly poorer than controls on intellectual, adaptive, learning, attention, and behavioral tasks. More mothers of children with FASD reported drinking prior to pregnancy and in the first and second trimesters, and had partners with drinking problems than mothers of controls; however, reports of comorbid alcohol use and 6 other drugs were similar for mothers of children with FASD and mothers of controls. Mothers of children with FASD were significantly younger at pregnancy, had lower average weight before pregnancy and less education, initiated prenatal clinic visits later, and reported more health problems (e.g., stomach ulcers and accidents). Children with FASD had significantly lower birth weight and more problems at birth, and were less likely to be living with biological mother and father. Controlling for other drug and tobacco use, a FASD diagnosis is 6.7 times (OR = 6.720, 95% CI = 1.6 to 28.0) more likely among children of women reporting prepregnancy drinking of 3 drinks per drinking day (DDD) and 7.6 times (OR = 7.590, 95% CI = 2.0 to 31.5) more likely at 5 DDD. Prevalence of FAS was 2.9-5.8 per 1,000 children, and total FASD was 34.9 to 82.5 per 1,000 children or 3.5 to 8.3% at this site. CONCLUSION: This site had the second highest prevalence of FASD of the 4 Collaboration on FASD Prevalence sites and clearly identifiable child and maternal risk traits.

Fetal Alcohol Spectrum Disorders in a Southeastern County of the United States: Child Characteristics and Maternal Risk Traits.

OBJECTIVE: To detail the characteristic traits of children with fetal alcohol spectrum disorders (FASDs) and maternal risk factors in a southeastern U.S. County. METHODS: Independent samples were drawn from 2 different cohorts of first-grade students. All consented children (49.8%) were measured for height, weight, and head circumference, and those ≤ 25th centile entered the study along with a random sample drawn from all enrolled students. Study children were examined for physical growth, dysmorphology, and neurobehavior, and their mothers were interviewed. RESULTS: Total dysmorphology scores discriminated well the physical traits of children across the FASD continuum: fetal alcohol syndrome (FAS) = 15.8, partial FAS (PFAS) = 10.8, alcohol-related neurobehavioral disorder (ARND) = 5.2, and typically developing controls = 4.4. Additionally, a neurobehavioral battery distinguished children with each FASD diagnosis from controls. Behavioral problems qualified more children for FASD diagnoses than cognitive traits. Significant proximal maternal risk variables were as follows: reports of prepregnancy drinking, drinking in any trimester, and comorbid use of other drugs in lifetime and during pregnancy, especially alcohol and marijuana (14.9% among mothers of children with FASD vs. 0.4% for controls). Distal maternal risks included reports of other health problems (e.g., depression), living unmarried with a partner during pregnancy, and a lower level of spirituality. Controlling for other drug use during pregnancy, having a child diagnosed with a FASD was 17.5 times greater for women who reported usual consumption of 3 drinks per drinking day prior to pregnancy than for nondrinking mothers (p < 0.001, 95% CI = 5.1 to 59.9). There was no significant difference in the prevalence of FASD by race, Hispanic ethnicity, or socioeconomic status. The prevalence of FASD was not lower than 17.3 per 1,000, and weighted estimated prevalence was 49.0 per 1,000 or 4.9%. CONCLUSION: This site had the second lowest rate in the CoFASP study, yet children with FASD are prevalent.

Fetal Alcohol Spectrum Disorders in a Midwestern City: Child Characteristics, Maternal Risk Traits, and Prevalence.

OBJECTIVE: To determine the characteristics of children with fetal alcohol spectrum disorders (FASD) and their mothers in a Midwestern city. METHODS: Case-control samples were drawn from 2 separate first-grade cohorts (combined N = 4,047) in every city school using different methods. In Cohort Sample 1, all consented small children (≤25th centile on height, weight, and/or head circumference) entered the study along with a random sample from all enrolled students. Cohort Sample 2 was drawn totally at random. Child growth, dysmorphology, and neurobehavior were assessed using the Collaboration on FASD Prevalence (CoFASP) criteria, and mothers were interviewed. RESULTS: For the samples combined, 891 children received dysmorphology examinations, and 692 were case-conferenced for final diagnosis. Forty-four children met criteria for FASD. Total dysmorphology scores differentiated diagnostic groups: fetal alcohol syndrome (FAS), 16.7; partial FAS, 11.8; alcohol-related neurodevelopmental disorder (ARND), 6.1; and typically developing controls, 4.2. Neurobehavioral tests distinguished children with FASD from controls, more for behavioral problems than cognitive delay. Children with ARND demonstrated the poorest neurobehavioral indicators. An adjusted regression model of usual prepregnancy drinking indicated that maternal reports of 3 drinks per drinking day (DDD) were significantly associated with a FASD diagnosis (p = 0.020, OR = 10.1, 95% CI = 1.44 to 70.54), as were 5 or more DDD (p < 0.001, OR = 26.47, 95% CI = 4.65 to 150.62). Other significant maternal risk factors included the following: self-reported drinking in any trimester; smoking and cocaine use during pregnancy; later pregnancy recognition and later and less prenatal care; lower maternal weight, body mass index (BMI), and head circumference; and unmarried status. There was no significant difference in FASD prevalence by race, Hispanic ethnicity, or socioeconomic status at this site, where the prevalence of FASD was 14.4 to 41.2 per 1,000 (1.4 to 4.1%). CONCLUSION: This city displayed the lowest prevalence of FASD of the 4 CoFASP sites. Nevertheless, FASD were common, and affected children demonstrated a common, recognizable, and measurable array of traits.

Early-Life Predictors of Fetal Alcohol Spectrum Disorders.

BACKGROUND AND OBJECTIVES: Fetal alcohol spectrum disorders (FASD) comprise the continuum of disabilities associated with prenatal alcohol exposure. Although infancy remains the most effective time for initiation of intervention services, current diagnostic schemes demonstrate the greatest confidence, accuracy, and reliability in school-aged children. Our aims for the current study were to identify growth, dysmorphology, and neurodevelopmental features in infants that were most predictive of FASD at age 5, thereby improving the timeliness of diagnoses. METHODS: A cohort of pregnant South African women attending primary health care clinics or giving birth in provincial hospitals was enrolled in the project. Children were followed longitudinally from birth to 60 months to determine their physical and developmental trajectories (N = 155). Standardized protocols were used to assess growth, dysmorphology, and development at 6 weeks and at 9, 18, 42, and 60 months. A structured maternal interview, including estimation of prenatal alcohol intake, was administered at 42 or 60 months. RESULTS: Growth restriction and total dysmorphology scores differentiated among children with and without FASD as early as 9 months (area under the receiver operating characteristic curve = 0.777; P < .001; 95% confidence interval: 0.705-0.849), although children who were severely affected could be identified earlier. Assessment of developmental milestones revealed significant developmental differences emerging among children with and without FASD between 18 and 42 months. Mothers of children with FASD were significantly smaller, with lower BMIs and higher alcohol intake during pregnancy, than mothers of children without FASD. CONCLUSIONS: Assessment of a combination of growth, dysmorphology, and neurobehavioral characteristics allows for accurate identification of most children with FASD as early as 9 to 18 months.

Birth outcomes in women who have taken adalimumab in pregnancy: A prospective cohort study.

BACKGROUND: Information is needed on the safety of adalimumab when used in pregnancy for the treatment of certain autoimmune diseases. METHODS AND FINDINGS: Between 2004 and 2016, the Organization of Teratology Information Specialists Research Center at the University of California San Diego conducted a prospective controlled observational cohort study in 602 pregnant women who had or had not taken adalimumab. Women in the adalimumab-exposed cohort had received at least one dose of the drug in the first trimester for the treatment of rheumatoid arthritis or Crohn's Disease (N = 257). Women in the disease comparison cohort had not used adalimumab in pregnancy (N = 120). Women in the healthy comparison cohort had no rheumatic or inflammatory bowel diseases (N = 225). Women and their infants were followed to one year postpartum with maternal interviews, medical records abstraction, and physical examinations. Study outcomes were major structural birth defects, minor defects, spontaneous abortion, preterm delivery, pre and post-natal growth deficiency, serious or opportunistic infections and malignancies. 42/602 (7.0%) of pregnancies were lost-to-follow-up. 22/221 (10.0%) in the adalimumab-exposed cohort had a live born infant with a major birth defect compared to 8/106 (7.5%) in the diseased unexposed cohort (adjusted odds ratio 1.10, 95% confidence interval [CI] 0.45 to 2.73). Women in the adalimumab-exposed cohort were more likely to deliver preterm compared to the healthy cohort (adjusted hazard ratio [aHR] 2.59, 95% CI 1.22 to 5.50), but not compared to the diseased unexposed cohort (aHR 0.82, 95% CI 0.66 to 7.20). No significant increased risks were noted with adalimumab exposure for any other study outcomes. CONCLUSIONS: Adalimumab exposure in pregnancy compared to diseased unexposed pregnancies was not associated with an increased risk for any of the adverse outcomes examined. Women with rheumatoid arthritis or Crohn's Disease were at increased risk of preterm delivery, irrespective of adalimumab exposure.

Prevalence of Fetal Alcohol Spectrum Disorders in 4 US Communities.

Importance: Fetal alcohol spectrum disorders are costly, life-long disabilities. Older data suggested the prevalence of the disorder in the United States was 10 per 1000 children; however, there are few current estimates based on larger, diverse US population samples. Objective: To estimate the prevalence of fetal alcohol spectrum disorders, including fetal alcohol syndrome, partial fetal alcohol syndrome, and alcohol-related neurodevelopmental disorder, in 4 regions of the United States. Design, Setting, and Participants: Active case ascertainment methods using a cross-sectional design were used to assess children for fetal alcohol spectrum disorders between 2010 and 2016. Children were systematically assessed in the 4 domains that contribute to the fetal alcohol spectrum disorder continuum: dysmorphic features, physical growth, neurobehavioral development, and prenatal alcohol exposure. The settings were 4 communities in the Rocky Mountain, Midwestern, Southeastern, and Pacific Southwestern regions of the United States. First-grade children and their parents or guardians were enrolled. Exposures: Alcohol consumption during pregnancy. Main Outcomes and Measures: Prevalence of fetal alcohol spectrum disorders in the 4 communities was the main outcome. Conservative estimates for the prevalence of the disorder and 95% CIs were calculated using the eligible first-grade population as the denominator. Weighted prevalences and 95% CIs were also estimated, accounting for the sampling schemes and using data restricted to children who received a full evaluation. Results: A total of 6639 children were selected for participation from a population of 13 146 first-graders (boys, 51.9%; mean age, 6.7 years [SD, 0.41] and white maternal race, 79.3%). A total of 222 cases of fetal alcohol spectrum disorders were identified. The conservative prevalence estimates for fetal alcohol spectrum disorders ranged from 11.3 (95% CI, 7.8-15.8) to 50.0 (95% CI, 39.9-61.7) per 1000 children. The weighted prevalence estimates for fetal alcohol spectrum disorders ranged from 31.1 (95% CI, 16.1-54.0) to 98.5 (95% CI, 57.5-139.5) per 1000 children. Conclusions and Relevance: Estimated prevalence of fetal alcohol spectrum disorders among first-graders in 4 US communities ranged from 1.1% to 5.0% using a conservative approach. These findings may represent more accurate US prevalence estimates than previous studies but may not be generalizable to all communities.

Who is most affected by prenatal alcohol exposure: Boys or girls?

OBJECTIVE: To examine outcomes among boys and girls that are associated with prenatal alcohol exposure. METHODS: Boys and girls with fetal alcohol spectrum disorders (FASD) and randomly-selected controls were compared on a variety of physical and neurobehavioral traits. RESULTS: Sex ratios indicated that heavy maternal binge drinking may have significantly diminished viability to birth and survival of boys postpartum more than girls by age seven. Case control comparisons of a variety of physical and neurobehavioral traits at age seven indicate that both sexes were affected similarly for a majority of variables. However, alcohol-exposed girls had significantly more dysmorphology overall than boys and performed significantly worse on non-verbal IQ tests than males. A three-step sequential regression analysis, controlling for multiple covariates, further indicated that dysmorphology among girls was significantly more associated with five maternal drinking variables and three distal maternal risk factors. However, the overall model, which included five associated neurobehavioral measures at step three, was not significant (p=0.09, two-tailed test). A separate sequential logistic regression analysis of predictors of a FASD diagnosis, however, indicated significantly more negative outcomes overall for girls than boys (Nagelkerke R2=0.42 for boys and 0.54 for girls, z=-2.9, p=0.004). CONCLUSION: Boys and girls had mostly similar outcomes when prenatal alcohol exposure was linked to poor physical and neurocognitive development. Nevertheless, sex ratios implicate lower viability and survival of males by first grade, and girls have more dysmorphology and neurocognitive impairment than boys resulting in a higher probability of a FASD diagnosis.

Replication of High Fetal Alcohol Spectrum Disorders Prevalence Rates, Child Characteristics, and Maternal Risk Factors in a Second Sample of Rural Communities in South Africa.

Background: Prevalence and characteristics of fetal alcohol syndrome (FAS) and total fetal alcohol spectrum disorders (FASD) were studied in a second sample of three South African rural communities to assess change. Methods: Active case ascertainment focused on children with height, weight and/or head circumference ≤25th centile and randomly-selected children. Final diagnoses were based on dysmorphology, neurobehavioral scores, and maternal risk interviews. Results: Cardinal facial features, head circumference, and total dysmorphology scores differentiated specific FASD diagnostic categories in a somewhat linear fashion but all FASD traits were significantly worse than those of randomly-selected controls. Neurodevelopmental delays were significantly worse for children with FASD than controls. Binge alcohol use was clearly documented as the proximal maternal risk factor for FASD, and significant distal risk factors were: low body mass, education, and income; high gravidity, parity, and age at birth of the index child. FAS rates continue to extremely high in these communities at 9-129 per 1000 children. Total FASD affect 196-276 per 1000 or 20-28% of the children in these communities. Conclusions: Very high rates of FASD persist in these general populations where regular, heavy drinking, often in a binge fashion, co-occurs with low socioeconomic conditions.

Findings from the Families on Track Intervention Pilot Trial for Children with Fetal Alcohol Spectrum Disorders and Their Families.

BACKGROUND: Individuals with fetal alcohol spectrum disorders (FASD) are at high risk for costly, debilitating mental health problems and secondary conditions, such as school disruption, trouble with the law, and substance use. The study objective was to pilot a multicomponent intervention designed to prevent secondary conditions in children with FASD and improve family adaptation. METHODS: Thirty children with FASD or prenatal alcohol exposure (PAE) (ages 4 to 8) and their primary caregivers were enrolled. Families were randomized to either the Families on Track Integrated Preventive Intervention or an active control of neuropsychological assessment and personalized community referrals. The 30-week intervention integrates scientifically validated bimonthly, in-home parent behavioral consultation, and weekly child skills groups. Outcomes measured at baseline and follow-up postintervention included intervention satisfaction, child emotional and behavioral functioning, child self-esteem, caregiver knowledge of FASD and advocacy, caregiver attitudes, use of targeted parenting practices, perceived family needs met, social support, and self-care. Data analysis emphasized calculation of effect sizes and was supplemented with analysis of variance techniques. RESULTS: Analyses indicated that families participating in the intervention reported high program satisfaction. Relative to comparison group outcomes, the intervention was associated with medium-to-large effects for child emotion regulation, self-esteem, and anxiety. Medium-sized improvements in disruptive behavior were observed for both groups. Medium and large effects were seen for important caregiver outcomes: knowledge of FASD and advocacy, attributions of behavior, use of antecedent strategies, parenting efficacy, family needs met, social support, and self-care. CONCLUSIONS: This pilot study yielded promising findings from the multicomponent Families on Track Integrated Preventive Intervention for child and caregiver outcomes. An important next step is to complete a randomized control trial of the Families on Track Program with a larger sample fully representative of this underserved clinical population with built-in study of implementation parameters.

The continuum of fetal alcohol spectrum disorders in a community in South Africa: Prevalence and characteristics in a fifth sample.

BACKGROUND: The prevalence and characteristics of the continuum of diagnoses within fetal alcohol spectrum disorders (FASD) were researched in a fifth sample in a South African community. METHODS: An active case ascertainment approach was employed among all first grade learners in this community (n=862). Following individual examination by clinical geneticists/dysmorphologists, cognitive/behavioral testing, and maternal interviews, final diagnoses were made in multidisciplinary case conferences. RESULTS: Physical measurements, cardinal facial features of FAS, and total dysmorphology scores clearly differentiated diagnostic categories in a consistent, linear fashion, from severe to mild. Neurodevelopmental delays and behavioral problems were significantly worse for each of the FASD diagnostic categories, although not as consistently linear across diagnostic groups. Alcohol use was documented by direct report from the mother in 71% to 100% of cases in specific diagnostic groups. Significant distal maternal risk factors in this population are: advanced maternal age at pregnancy; low height, weight, and body mass index (BMI); small head circumference; low education; low income; and rural residence. Even when controlling for socioeconomic status, prenatal drinking correlates significantly with total dysmorphology score, head circumference, and five cognitive and behavioral measures. In this community, FAS occurs in 59-79 per 1,000 children, and total FASD in 170-233 per 1,000 children, or 17% to 23%. CONCLUSIONS: Very high rates of FASD continue in this community where entrenched practices of regular binge drinking co-exist with challenging conditions for childbearing and child development in a significant portion of the population.
