Breastfeeding and maternal alcohol use: Prevalence and effects on child outcomes and fetal alcohol spectrum disorders.
Ontology highlight
ABSTRACT: Objective
Determine any effects that maternal alcohol consumption during the breastfeeding period has on child outcomes.Methods
Population-based samples of children with fetal alcohol spectrum disorders (FASD), normally-developing children, and their mothers were analyzed for differences in child outcomes.Results
Ninety percent (90%) of mothers breastfed for an average of 19.9 months. Of mothers who drank postpartum and breastfed (MDPB), 47% breastfed for 12 months or more. In case control analyses, children of MDPB were significantly lighter, had lower verbal IQ scores, and more anomalies in comparisons controlling for prenatal alcohol exposure and final FASD diagnosis. Utilizing a stepwise logistic regression model adjusting for nine confounders of prenatal drinking and other maternal risks, MDPB were 6.4 times more likely to have a child with FASD than breastfeeding mothers who abstained from alcohol while breastfeeding.Conclusions
Alcohol use during the period of breastfeeding was found to significantly compromise a child's development.

Project description:ObjectiveTo determine the characteristics of children with fetal alcohol spectrum disorders (FASD) and their mothers in a Midwestern city.MethodsCase-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.ResultsFor 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%).ConclusionThis 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.

Project description:ObjectiveTo document prevalence and traits of children with fetal alcohol spectrum disorders (FASD) and maternal risk factors in a Rocky Mountain city.MethodsVariations 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.ResultsThirty-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.ConclusionThis site had the second highest prevalence of FASD of the 4 Collaboration on FASD Prevalence sites and clearly identifiable child and maternal risk traits.

Project description:ObjectiveTo 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).MethodsAggregated, 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.ResultsMothers 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.ConclusionsDifferences 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.

Project description:ImportanceFetal 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.ObjectiveTo 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 participantsActive 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.ExposuresAlcohol consumption during pregnancy.Main outcomes and measuresPrevalence 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.ResultsA 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 relevanceEstimated 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.

Project description:ObjectiveTo detail the characteristic traits of children with fetal alcohol spectrum disorders (FASDs) and maternal risk factors in a southeastern U.S. County.MethodsIndependent 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.ResultsTotal 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%.ConclusionThis site had the second lowest rate in the CoFASP study, yet children with FASD are prevalent.

Project description:BackgroundThis 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.MethodsPopulation-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.ResultsConsent 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.ConclusionThe 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.

Project description:Fetal alcohol spectrum disorders (FASD) are thought to be the leading cause of developmental disabilities worldwide. Accurate estimates of the prevalence of FASD have been lacking. An improved estimate of FASD prevalence in the U.S. was recently reported in a study where multistage methods of active case ascertainment of first-grade children with FASD were utilized in four regions in the U.S. Each method relied on parental consent and therefore had potential non-response bias. We consider weighted approaches, where the weights were formed using the distribution of observed variables in the population from which the samples were drawn. However, there are likely other unobserved variables that affect both non-response and FASD outcome. We describe sensitivity analyses using methodology developed for causal inference. The results show feasible regions of FASD prevalence under certain assumptions, and provide a framework for explaining the non-response bias due to the unobserved variables.

Project description:IntroductionUp to 9.9% of children have fetal alcohol spectrum disorders (FASD), the most frequent cause of intellectual disability in the US. FASD may involve abnormal brain development, including dysmyelination, suggesting abnormal development of oligodendrocytes (OLs), which make myelin and are rich in lipids. Indeed, low serum levels of omega-3 fatty acids (ω-3) have been reported in FASD. Free fatty acids bind to specific receptors (FFARs). We have isolated cell type-specific fetal brain-derived exosomes (FB-E) from maternal blood and sampled their contents to search for lipid-related biomarkers that predict FASD.MethodsBlood samples were collected from two groups of pregnant women: 1) those who consumed EtOH during pregnancy, and 2) non-EtOH using controls, under an IRB-approved protocol. Serum and OL-derived exosomes (OL-Es) were used to assay myelin basic protein (MBP) and FFAR by ELISA and droplet digital PCR (ddPCR), respectively.ResultsFFAR and MBP proteins were downregulated in the EtOH group compared to controls, and this difference was greatest in OL-Es from maternal blood compared maternal serum.ConclusionMBP and FFAR levels were reduced in OL-Es from EtOH-consuming pregnant women. The data suggest potential therapeutic targets to predict which children are at risk for developing FASD and reduce dysmyelination in developing.

Project description:BackgroundMaternal risk factors for fetal alcohol spectrum disorders (FASD) in Italy and Mediterranean cultures need clarification, as there are few studies and most are plagued by inaccurate reporting of antenatal alcohol use.MethodsMaternal interviews (n = 905) were carried out in a population-based study of the prevalence and characteristics of FASD in the Lazio region of Italy which provided data for multivariate case control comparisons and multiple correlation models.ResultsCase control findings from interviews seven years post-partum indicate that mothers of children with FASD are significantly more likely than randomly-selected controls or community mothers to: be shorter; have higher body mass indexes (BMI); be married to a man with legal problems; report more drinking three months pre-pregnancy; engage in more current drinking and drinking alone; and have alcohol problems in her family. Logistic regression analysis of multiple candidate predictors of a FASD diagnosis indicates that alcohol problems in the child's family is the most significant risk factor, making a diagnosis within the continuum of FASD 9 times more likely (95%C.I. = 1.6 to 50.7). Sequential multiple regression analysis of the child's neuropsychological performance also identifies alcohol problems in the child's family as the only significant maternal risk variable (p < .001) when controlling for other potential risk factors.ConclusionsUnderreporting of prenatal alcohol use has been demonstrated among Italian and other Mediterranean antenatal samples, and it was suspected in this sample. Nevertheless, several significant maternal risk factors for FASD have been identified.

Project description:BackgroundPrevalence and characteristics of fetal alcohol spectrum disorders (FASD) have been described previously in this community.MethodsActive 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.ResultsChildren 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.ConclusionSeventeen 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.
