Fetal Alcohol Syndrome (FAS) is a preventable disorder that affects children worldwide. It is caused when a pregnant person consumes alcohol, which can result in permanent brain damage, congenital anomalies, prenatal or postnatal growth restriction, and characteristic facial features in the child. FAS is a global health issue, with an estimated 119,000 children born with the condition annually. The prevalence of FAS varies across countries and regions, with Europe having a 2.6 higher prevalence than the global average, while the Eastern Mediterranean and Southeast Asia regions have the lowest levels. The effects of prenatal alcohol exposure are now categorized under the umbrella term Fetal Alcohol Spectrum Disorder (FASD), which includes FAS, partial FAS, alcohol-related neurodevelopmental disorders, and alcohol-related birth defects. The establishment of universal public health messages and routine screening protocols is essential to address this issue.

What You'll Learn
Global prevalence of fetal alcohol syndrome
Fetal Alcohol Syndrome (FAS) is a preventable disorder that is caused by alcohol consumption during pregnancy. It can result in permanent brain damage, congenital anomalies, prenatal or postnatal growth restriction, and characteristic dysmorphic facial features. It is also associated with a range of comorbid conditions, including mental and behavioural disorders.
The global prevalence of FAS is estimated to be 14.6 per 10,000 people, which translates to about 119,000 children born with FAS annually worldwide. These estimates highlight the urgent need for effective prevention strategies and improved surveillance of FAS.
The prevalence of FAS varies across different regions and countries. Europe, for instance, has a 2.6 times higher prevalence of FAS than the global average, with Russia, the United Kingdom, Denmark, Belarus, and Ireland having the highest alcohol use during pregnancy within the region. In contrast, the Eastern Mediterranean and Southeast Asia regions exhibit the lowest levels of drinking and FAS due to high rates of alcohol abstinence.
It is worth noting that the estimation of FAS prevalence is challenging due to variations in data collection methods, sample populations, and the inclusion or exclusion of abstainers in studies. Additionally, factors such as maternal metabolism, genetic background, environmental influences, maternal age, smoking, nutritional status, stress levels, and paternal lifestyle can further modify fetal susceptibility to the effects of alcohol consumption.
Updated and accurate prevalence estimates are crucial for prioritizing healthcare expenditures, planning interventions, and allocating resources for healthcare and prevention related to FAS.

Alcohol use during pregnancy
Despite the well-established adverse effects of alcohol consumption during pregnancy, it remains prevalent, especially in certain regions. For example, a study in four Sub-Saharan African countries (Burundi, Ethiopia, Liberia, and Zimbabwe) found a high prevalence of alcohol use during pregnancy, with an overall rate of 22.8%. Similarly, in Canada, about 10% of women reported drinking at some point during their pregnancy, and in Australia, nearly one in three pregnant women reported consuming alcohol.
The persistence of alcohol use during pregnancy, despite education campaigns and public health messages advising abstinence, highlights the complexity of the issue. It is important to recognize that even low levels of alcohol consumption during pregnancy can lead to negative outcomes for the developing fetus. Recent studies have shown that prenatal alcohol exposure can affect both facial and brain development, leading to distinct facial features and developmental concerns. These effects may not always be directly linked to developmental issues, but they highlight the hidden biological consequences of alcohol use during pregnancy.
To address this global health issue, effective prevention strategies are needed. This includes establishing universal public health messages about the potential harm of prenatal alcohol exposure and implementing routine screening protocols for all women of childbearing age. Brief interventions should also be provided where appropriate, and targeted health messaging should support informed decision-making during pregnancy. Additionally, it is important to consider social influences, individual attitudes, and personal experiences when developing health messaging to ensure it resonates with a diverse audience.
In conclusion, alcohol use during pregnancy is a significant global health issue that requires urgent attention. The prevalence of alcohol consumption during pregnancy and the resulting cases of FAS highlight the need for effective prevention strategies and targeted health messaging to support women in making informed choices about their alcohol consumption during pregnancy.

Fetal alcohol spectrum disorder (FASD)
The global prevalence of alcohol use during pregnancy is estimated to be about 9.8%, and the estimated prevalence of FASD in the general population is 14.6 per 10,000 people. This means that one in every 67 women who consume alcohol during pregnancy will deliver a child with FASD, resulting in about 119,000 children being born with FASD every year worldwide.
The prevalence of FASD varies across different regions and countries. For example, Europe has a 2.6 times higher prevalence of FASD than the global average, with Russia, the United Kingdom, Denmark, Belarus, and Ireland being the top five countries with the highest alcohol use during pregnancy. In contrast, the Eastern Mediterranean and Southeast Asia regions have the lowest levels of drinking and FASD due to high rates of alcohol abstinence.
The development of FASD is influenced by multiple factors beyond the amount of alcohol consumed and the timing of consumption during pregnancy. These factors include the metabolism and genetic background of the mother and fetus, environmental influences, maternal age, smoking, nutritional status, stress levels, and possibly paternal lifestyle.
The prevention of FASD requires effective public health messaging about the potential harm of prenatal alcohol exposure and the establishment of routine screening protocols. Brief interventions should also be provided where appropriate. Updated prevalence estimates are essential for prioritizing healthcare expenditures and allocating resources for the prevention and management of FASD.

Prevention strategies
Fetal Alcohol Spectrum Disorder (FASD) is a prevalent alcohol-related developmental disability that is entirely preventable if a developing fetus is not exposed to alcohol. Alcohol consumption during pregnancy can cause a wide range of adverse health effects on the developing fetus, including cognitive, behavioral, emotional, and adaptive functioning deficits, as well as congenital anomalies.
- Universal Public Health Message: Establish a universal public health message about the potential harm of prenatal alcohol exposure. This includes raising awareness about the effects of alcohol consumption during pregnancy and the risks associated with it. This information should be widely disseminated to the general public, with a focus on women of childbearing age, their partners, families, and the broader community.
- Routine Screening and Early Intervention: Implement routine screening protocols for alcohol use during pregnancy. Healthcare providers should ask all female patients of childbearing age about their alcohol consumption. If a woman is identified as being at high risk, early intervention programs and services should be offered, and she should be referred to appropriate support and treatment. Screening, early intervention, and referral to treatment can be done using approaches such as the "Screening, Brief Intervention, and Referral to Treatment (SBIRT)" model.
- Education and Counseling: Engage in education and counseling about FASD and the adverse effects of alcohol on the fetus. This includes providing information about the risks and consequences of drinking during pregnancy or when planning a pregnancy. Healthcare professionals should be trained to have these conversations and provide counseling to support women in reducing or stopping alcohol consumption.
- Community-Led Initiatives: Encamp community-led initiatives to address FASD and build knowledge and awareness within communities. For example, the Marulu Strategy in Australia focuses on preventing FASD by working with community members, health agencies, and community organizations to reduce alcohol consumption during pregnancy.
- Reduce Access to Alcohol: Implement policies and regulations to reduce access to and consumption of alcohol in communities. This can include legal restrictions on the sale of full-strength alcohol, as well as addressing social norms around alcohol consumption.
- Research and Intervention Development: Support research and the development of effective interventions for FASD prevention. This includes examining the translation of biopsychosocial, community-based, and policy approaches into practice to prevent prenatal alcohol exposure. Design and evaluate cost-effective interventions, particularly for high-risk and vulnerable populations.

Congenital anomalies and other health effects
Fetal Alcohol Syndrome (FAS) is a direct consequence of alcohol consumption during pregnancy. It is a significant global health issue, with an estimated global prevalence of 14.6 per 10,000 people, translating to approximately 119,000 children born with FAS annually worldwide.
The health effects of prenatal exposure to alcohol are grouped under the umbrella term Fetal Alcohol Spectrum Disorder (FASD), which includes fetal alcohol syndrome (FAS), partial FAS, alcohol-related neurodevelopmental disorders, and alcohol-related birth defects.
- Permanent brain damage: Alcohol is a teratogen that crosses the placenta, damaging the brain and other organs of the developing fetus. This can lead to neurodevelopmental impairments and substantial secondary disabilities later in life.
- Growth restriction: Alcohol use during pregnancy is linked to prenatal and postnatal growth restriction, resulting in low birth weight.
- Dysmorphic facial features: Children with FAS often exhibit distinctive facial characteristics.
- Cognitive, behavioral, and emotional deficits: FAS is associated with a range of comorbid conditions, including cognitive, behavioral, and emotional problems, which can be highly prevalent in individuals with FAS, ranging from 50% to 91%.
- Adaptive functioning deficits: In addition to cognitive and behavioral issues, children with FAS may struggle with adaptive functioning, impacting their ability to adapt to their environment and learn new skills.
- Congenital malformations, deformities, and chromosomal abnormalities: These are among the most prevalent conditions associated with FAS, affecting 43% of individuals with the disorder.
The prevalence of FAS and FASD varies across different regions and countries. Europe, for instance, has a 2.6 times higher prevalence of FAS than the global average, with Russia, the United Kingdom, Denmark, Belarus, and Ireland having the highest alcohol use during pregnancy in the region. In contrast, the Eastern Mediterranean and Southeast Asia regions have the lowest levels of drinking and FAS due to high rates of alcohol abstinence.
The variability in prevalence rates highlights the need for country-specific and region-specific studies to accurately assess the burden of FAS and FASD. This information is crucial for developing effective public health messages, prevention strategies, and interventions to address the global health issue of FAS and FASD.
