Birth defects and alcohol
Birth defects related to alcohol consumption during pregnancy are significant public health concerns, primarily arising from fetal alcohol exposure. This exposure is linked to a range of congenital disabilities and developmental disorders, making it one of the leading causes of such conditions. Research from the Centers for Disease Control and Prevention (CDC) indicates that approximately 0.2 to 1.5 infants per 1,000 live births in the U.S. may be affected by fetal alcohol exposure. When a pregnant woman consumes alcohol, it readily crosses the placenta, potentially leading to lifelong issues for the child, including intellectual impairments and behavioral problems.
Fetal Alcohol Syndrome (FAS) is a severe manifestation of these effects, characterized by distinct facial features, growth deficiencies, and central nervous system challenges. Although FAS is irreversible, early diagnosis and support can help affected children reach their full potential. The broader category of Fetal Alcohol Spectrum Disorders (FASD) encompasses various conditions resulting from prenatal alcohol exposure, highlighting the spectrum of severity and symptoms.
To prevent FASD, the most effective approach is complete abstinence from alcohol during pregnancy, as even small amounts can pose risks. Community support, education, and intervention are crucial in preventing these disorders, emphasizing the collective responsibility to address alcohol use in pregnant women. Ongoing research continues to explore the implications of alcohol use among both men and women, contributing to more comprehensive prevention strategies.
Birth defects and alcohol
DEFINITION: Fetal alcohol exposure is one of the leading causes of congenital disabilities and developmental disorders. Estimates from the Centers for Disease Control and Prevention (CDC) in 2021 place the number of children in the United States (US) affected by fetal alcohol exposure at approximately 0.2 to 1.5 infants for every 1,000 live births.
The Dangers of Drinking for Two
When a pregnant woman drinks alcoholic beverages, the alcohol in her blood crosses the placenta easily and enters the embryo or fetus through the umbilical cord. Children affected by prenatal exposure to alcohol may suffer lifelong consequences, including intellectual impairment, learning disabilities, and serious behavioral problems.
All drinks containing alcohol can hurt a fetus. A standard twelve-ounce can of beer has the same amount of alcohol as a four-ounce glass of wine or a one-ounce shot of straight liquor. In addition, some alcoholic drinks, such as malt beverages, wine coolers, and mixed drinks, often contain more alcohol than a twelve-ounce can of beer. Studies have not been done to establish a known safe amount of alcohol that a woman can drink while pregnant.
Any time a pregnant woman participates in regular drinking increases her chance of having a miscarriage and puts her unborn child at risk for growth deficiencies, learning disabilities, and behavioral problems. Congenital disabilities associated with prenatal exposure to alcohol can occur in the first eight weeks of pregnancy before a woman even knows that she is pregnant.
Between 2015 and 2017, one in nine pregnant women surveyed reported alcohol use, and about 4 percent reported binge drinking within thirty days of the survey, according to the CDC. These numbers have remained steady despite myriad studies showing a negative correlation between drinking alcohol and the health of a child. In 2020, 13.5 percent of pregnant women reported drinking during their pregnancy, and 5.2 percent reported binge drinking.
Fetal Alcohol Syndrome
Fetal alcohol syndrome (FAS) is caused by alcohol consumption during pregnancy and is one of the leading known causes of mental, physical, and congenital disabilities. It is characterized by abnormal facial features, including small head size, narrow eye slits, abnormalities of the nose and lip areas, growth deficiencies, and problems with the central nervous system (CNS).
Children with FAS may have problems with learning, memory, attention span, problem-solving, speech, and hearing. These problems often lead to difficulties in school and getting along with others. FAS is an irreversible condition that affects every aspect of a child’s life and the lives of their family. FAS is preventable if a woman abstains from alcohol while she is pregnant.
Fetal Alcohol Effects
In the past, the term "fetal alcohol effects (FAE)" was generally used to describe children who did not have all of the clinical signs of FAS, but who had various problems, including growth deficiency, behavioral problems, or problems with motor and speech skills. FAE has also been used to describe children who have all of the diagnostic features of FAS, but at mild levels. Because experts in the field were unable to agree on a single definition for FAE, the Institute of Medicine (IOM) proposed the terms alcohol-related neurodevelopment disorder (ARND) and alcohol-related birth defects (ARBD). ARND describes the functional or mental impairments linked to prenatal alcohol exposure, such as behavioral or cognitive abnormalities. These include learning difficulties, poor school performance, poor impulse control, and problems with mathematical skills, memory, attention, and judgment. ARBD describes malformations of the skeletal system and major organ systems. Such malformations may include defects of the heart, kidneys, bones, and auditory system.
By the mid-2020s, the medical community had begun referring to instances of FAS as Fetal Alcohol Spectrum Disorders (FASD). This change to identifying FAS as a spectrum disorder indicates the complex range of conditions resulting from the exposure of a fetus to alcohol. FAS is the most severe of FASD, while ARND and ARBD are recognized as lying in other areas on the spectrum.
Treatment and Prevention
There is no cure for either fetal alcohol syndrome or fetal alcohol effects. They are irreversible, lifelong conditions that affect every aspect of a child’s development. With early identification and diagnosis, a child with FASD can receive services that can help to maximize their potential.
The easiest way to prevent FASD is to abstain from alcohol use during pregnancy. Any amount of alcohol consumed during pregnancy is potentially dangerous to an unborn baby. If a pregnant woman is drinking during pregnancy, it is never too late for her to stop. The sooner a woman quits drinking, the better it will be for her and her baby. If a woman is not able to quit drinking, she should contact her local social service agency or health plan for alcohol abuse treatment, if needed. If a woman is not yet pregnant, she should use an effective form of birth control until her drinking is under control.
However, mothers are not the only ones who can help prevent FASD. Significant others, such as family members, schools, social organizations, and communities, can help prevent FASD through education and intervention. Also, emerging research suggests that long-term alcohol abuse among men may alter sperm cells in ways that introduce defects to the fetus at conception. Continued research will help to clarify this link and improve prevention efforts.
