Fetal Alcohol Spectrum Disorders: an International Perspective:

What research is being done on prenatal alcohol exposure and fetal alcohol spectrum disorders in the Russian research community?

AIMS

Although Russia has one of the highest rates of alcohol consumption and alcohol-attributable burden of disease, little is known about the existing research on prenatal alcohol exposure (PAE) and Fetal Alcohol Spectrum Disorders (FASDs) in this country. The objective of this study was to locate and review published and unpublished studies related to any aspect of PAE and FASD conducted in or using study populations from Russia.

METHODS

A systematic literature search was conducted in multiple English and Russian electronic bibliographic databases. In addition, a manual search was conducted in several major libraries in Moscow.

RESULTS

The search revealed a small pool of existing research studies related to PAE and/or FASD in Russia (126: 22 in English and 104 in Russian). Existing epidemiological data indicate a high prevalence of PAE and FASD, which underlines the strong negative impact that alcohol has on mortality, morbidity and disability in Russia. High levels of alcohol consumption by women of childbearing age, low levels of contraception use, and low levels of knowledge by health and other professionals regarding the harmful effects of PAE put this country at great risk of further alcohol-affected pregnancies.

CONCLUSIONS

Alcohol preventive measures in Russia warrant immediate attention. More research focused on alcohol prevention and policy is needed in order to reduce alcohol-related harm, especially in the field of FASD.

Collaborative initiative on fetal alcohol spectrum disorders: methodology of clinical projects

The Collaborative Initiative on Fetal Alcohol Spectrum Disorders (CIFASD) was created in 2003 to further understanding of fetal alcohol spectrum disorders. Clinical and basic science projects collect data across multiple sites using standardized methodology. This article describes the methodology being used by the clinical projects that pertain to assessment of children and adolescents. Domains being addressed are dysmorphology, neurobehavior, 3-D facial imaging, and brain imaging.

Systematic review of interventions for children with Fetal Alcohol Spectrum Disorders

BACKGROUND

Children with Fetal Alcohol Spectrum Disorders (FASD) may have significant neurobehavioural problems persisting into adulthood. Early diagnosis may decrease the risk of adverse life outcomes. However, little is known about effective interventions for children with FASD. Our aim is to conduct a systematic review of the literature to identify and evaluate the evidence for pharmacological and non-pharmacological interventions for children with FASD.

METHODS

We did an electronic search of the Cochrane Library, MEDLINE, EMBASE, PsychINFO, CINAHL and ERIC for clinical studies (Randomized controlled trials (RCT), quasi RCT, controlled trials and pre- and post-intervention studies) which evaluated pharmacological, behavioural, speech therapy, occupational therapy, physiotherapy, psychosocial and educational interventions and early intervention programs. Participants were aged under 18 years with a diagnosis of a FASD. Selection of studies for inclusion and assessment of study quality was undertaken independently by two reviewers. Meta-analysis was not possible due to diversity in the interventions and outcome measures.

RESULTS

Twelve studies met the inclusion criteria. Methodological weaknesses were common, including small sample sizes; inadequate study design and short term follow up. Pharmacological interventions, evaluated in two studies (both RCT) showed some benefit from stimulant medications. Educational and learning strategies (three RCT) were evaluated in seven studies. There was some evidence to suggest that virtual reality training, cognitive control therapy, language and literacy therapy, mathematics intervention and rehearsal training for memory may be beneficial strategies. Three studies evaluating social communication and behavioural strategies (two RCT) suggested that social skills training may improve social skills and behaviour at home and Attention Process Training may improve attention.

CONCLUSION

There is limited good quality evidence for specific interventions for managing FASD, however seven randomized controlled trials that address specific functional deficits of children with FASD are underway or recently completed.

Math performance and behavior problems in children affected by prenatal alcohol exposure: intervention and follow-up

OBJECTIVE

Fetal alcohol spectrum disorders (FASD), resulting from maternal alcohol use during pregnancy, are associated with significant academic and behavior problems. Although affected children are common in clinical practice, information to guide recommendations about interventions with this high risk group is very limited. This study evaluated the persistence of effects of an intervention on the math performance and behavior of 54 children, 3- to 10-years, diagnosed with fetal alcohol syndrome or FASD.

METHODS

Children were randomly assigned to a 6-week Math intervention (n = 28) tailored to this clinical group or to a standard psychoeducational contrast group (n = 26). All caregivers received identical educational interventions to promote learning readiness and improve behavioral outcomes. In a previous study, participants were assessed before interventions and immediately following completion. In this follow-up study, participants were recontacted and reassessed at 6 months post completion to determine if positive results on math functioning and child behavior would persist after treatment discontinuation.

RESULTS

Focus was on 2 outcomes: (1) Math performance, assessed using standardized measures of math achievement and (2) Behavior problems as reported by caregivers on the Child Behavior Checklist (CBCL) and teachers on the Teacher Report Form (TRF). Experimental-group participants demonstrated significantly greater scores on math outcome measures than Contrast group members and CBCL and TRF behavior was improved over pretest scores in both groups.

CONCLUSION

This 6-month follow-up confirms that both math skills and behavior of alcohol-affected children are improved significantly by interventions designed to meet their specific learning and behavior needs.

Socio-cognitive habilitation using the math interactive learning experience program for alcohol-affected children

BACKGROUND

Fetal alcohol syndrome (FAS) has been recognized as a disabling condition with a significant impact on the neurobehavioral functioning of affected individuals, including cognition, behavior, and academic functioning, but little research has been performed on targeted interventions for these children.

METHODS

A socio-cognitive habilitative program focused on improving behavior and math functioning in children 3 to 10 years of age (n=61) was developed and evaluated. The intervention provided parental instruction on FAS, advocacy, and behavioral regulation via workshops and interactive math tutoring with children. All families received parental instruction and were then randomly assigned to either the math instruction or standard psychoeducational care groups.

RESULTS

Satisfaction with workshops was very high, with over 90% agreeing that trainers were knowledgeable and materials easy to understand and helpful. Significant gains in knowledge were found for information provided in the instructional groups. At posttesting, caregivers reported fewer problem behaviors on the Achenbach Child Behavior Checklist, Internalizing Problem Behavior, Externalizing Problem Behavior, and Total Problem Behavior summary scales. After 5 months, both groups of children demonstrated gains in math knowledge but significantly higher gains were found in the group receiving direct math instruction. The math treatment group was also more likely to demonstrate a gain of over 1 standard deviation on any of the 4 math outcome measures used.

CONCLUSIONS

These findings suggest that parents of children with fetal alcohol spectrum disorders (FAS(D)) benefit from instruction in understanding their child's alcohol-related neurological damage and strategies to provide positive behavioral supports and that targeted psychoeducational programs may be able to remediate some of the math deficits associated with prenatal alcohol exposure.

Clinical delineation of fetal alcohol spectrum disorders (FASD) in Italian children: comparison and contrast with other racial/ethnic groups and implications for diagnosis and prevention

In Italy, little is known about the spectrum of adverse fetal effects related to maternal alcohol use during pregnancy. In this paper, we report on the phenotype of Italian children with fetal alcohol spectrum disorders (FASD). These data were gathered as part of a field study assessing the prevalence of FASD in children in an in-school study in a rural area near Rome. The purposes of this paper are: (1) to completely characterize the clinical phenotype of a large cohort of Italian children with FASD; (2) to correlate and contrast the phenotype of this population with that observed in other populations and reported in the medical literature; (3) to discuss the drinking habits of Italian women, before, during and after pregnancy; and (4) to suggest mechanisms for intervention and prevention of FASD based on data gathered from this study.

Epidemiology of FASD in a Province in Italy: Prevalence and Characteristics of Children in a Random Sample of Schools

BACKGROUND

Accurate estimates of the prevalence and characteristics of fetal alcohol syndrome (FAS) and fetal alcohol spectrum disorders (FASD) in a Western European population are lacking and are of particular interest in settings where the usual pattern of alcohol consumption is thought to be daily drinking with meals. To address these issues, an epidemiology study of FAS and other FASD was undertaken in Italian schools.

METHODS

Primary schools (n = 25) in 2 health districts of the Lazio region were randomly selected and recruited for the study. Five hundred forty-three children, 50% of those enrolled in first-grade classes, received parental permission to participate in a 2-tiered, active case ascertainment screening process. Detailed evaluation of children selected in a preliminary screening phase was carried out on those who were small for height, weight, and head circumference and/or referred by teachers for suspected learning and behavioral problems. Detailed evaluation was carried out on each child's: (1) physical growth and dysmorphology, (2) psychological development and behavior, and (3) prenatal exposure to alcohol and other risk factors for FASD via maternal interviews. A group of 67 randomly selected children without FASD from the same classes was utilized as a comparison group.

RESULTS

Using 2 denominators for prevalence estimation, a conservative one and a strict sample-based estimate, the prevalence of FAS in this province of Italy was 3.7 to 7.4 per 1,000 children. When cases of partial FAS (PFAS) and a case of alcohol-related neurodevelopmental deficits (ARND) were added to FAS cases, the rate of FASD was 20.3 to 40.5 per 1,000 and estimated at 35 per 1,000 overall or between 2.3 and 4.1% of all children. This exceeds previously published estimates of both FAS and FASD for the western world. Detailed data are presented that demonstrate the utility of the guidelines of the revised Institute of Medicine diagnostic criteria for FASD. Children with FASD are significantly more impaired/affected (p < 0.05) than randomly selected comparison children on all measures of growth deficiency, key facial features of FASD, overall dysmorphology scores, language comprehension, nonverbal IQ, and behavior. Maternal reports of current drinking were significantly higher for mothers of FASD children than comparison mothers, but reported rates of overall drinking during pregnancy were not significantly different. In contrast to expectations, daily drinking among mothers of the comparison group was not common. However, dysmorphology scores of the children were significantly correlated with drinking in the second and third trimesters, drinks per current drinking day, and current drinks per month. Finally, children with the physical features of FASD had lower IQs; nonverbal IQ was significantly correlated with head circumference and negatively correlated with overall dysmorphology score, smooth philtrum, and several other facial and physical anomalies characteristic of FAS.

CONCLUSIONS

Using careful measures of ascertainment in a primary school setting, these results provide relatively high estimates of the prevalence of FASD and raise the question of whether FASD is more common in the western world than previously estimated.
