A wedding ritual forbade drinking of wine by the bridal couple so that a defective child would not be conceived (Ancient Carthage)
Behold, thou shall conceive and bear a
son: and now drink no wine or strong drink
Judges 13:4
Alcohol should be barred “to any man or woman who was intending to create children. Children should not be made in bodies saturated with drunkenness”. (Plato)
““Parental drinking is a cause of weak, feeble, and distempered children” (College of Physicians to the British Parliament 1726)

First scientific study on fetal effects: Sullivan in 1899 who found women who drank had a 56% increase in stillbirths and infant death 2 ½ times higher than those did not drink.
In 1942, after prohibition, a paper was published with the erroneous information that the fetus was protected in the womb.
In late 1960s, Dr. C Ulleland noted failure to thrive in infants whose mothers consumed alcohol, during pregnancy, in spite of healthy post natal environment.
Modern concept of FAS was first identified in 1968 by the French (Lemoine et al).
The term FAS was coined by Smith and Jones in the U.S. in 1973 to describe a constellation of characteristics noted in children examined by Dr. Ulleland.
In 1989, “The Broken Cord,” by Michael Dorris is published, a personal account by an adoptive father, was published.
In 2000, Linda Belle LaFever wrote a first hand account of her child with FAS and her struggle with alcoholism in “ Cheers! Here’s To The Baby”
EpidemiologyEpidemiology
Alcohol problems are increasing in adolescent girls and older women. 17.7% of women age 12-17 yrs used alcohol in the last month; 10.6% of them binged (FASD Center of Excellence,2004)
Women have a greater mortality rate and greater sensitivity to effects of alcohol than men.
Up to 80% of women with a substance abuse problem also have some form of psychiatric co-morbidity.
From 1991-1995, CDC reported a 4-fold increase in frequent(7+ drinks per week) and binge(5+ on one occasion) drinking during pregnancy.
9-12% of pregnant women in US report consuming alcohol and 3% report drinking at levels that have consistently been associated with adverse effects on the fetus CDC. 2005).
More than half of all women of childbearing age (18-44) report alcohol use; 1 in 8 report binge drinking within the last month.
Birth defects due to prenatal alcohol use can
occur in the first 3-8 weeks of pregnancy,
before most women know they are pregnant.
Animal Models and Prenatal Alcohol
Many studies cannot be done on humans
Confounding factors can rarely be controlled in human studies
Alcohol is rarely the only drug used
Many abnormalities occur at low rates
Epidemiological studies are time consuming and expensive

In one study, of 72 mouse pups tested:
• 2 did not develop brains
• 30 presented with eye and oral malformations
• Several pups were not affected
• Regular use of alcohol was not necessary to alter brain development

Genetics May Be Involved in FAS
Identical twins are derived from a single egg, whereas fraternal twins are derived from two eggs. Thus, identical twins are more similar genetically.The child on the left is considerably more affected than his fraternal twin.Identical twins are more likely than fraternal twins to demonstrate similar FAS effects, suggesting a potential role for genetics in the expression of FAS.
The fraternal twins pictured to the left are 17 months old.

Challenges in determining accurate prevalence:
No uniform, widely accepted diagnostic criteria (IOM, CDC, Seattle)
FAS diagnosis is based on clinical examination of features, but not all children with FAS look or act the same
Lack of knowledge and misconceptions among primary care providers.
Incidence Rates
An individual with FAS can incur a lifetime health cost of over $800,000 - $1.2 mil.
In 1998, the annual cost of FAS in the United States was estimated at $2.8 billion. In 2003, the estimated cost was $5.4 billion; direct costs were $3.9 billion and indirect costs were another $1.5 billion.
FAS and related conditions are estimated to cost between $75 million and $9.7 billion annually in the United States.
What is FAS?
Fetal Alcohol Syndrome (FAS) is a life long birth defect caused
by maternal consumption of alcohol during pregnancy.

FAS – Only the tip of the Iceberg
Fetal Alcohol Spectrum Disorders ( FASD) refers to the broad spectrum of disorders caused by prenatal exposure to alcohol including:
FAS (Fetal Alcohol Syndrome) FAE (Fetal Alcohol Effects) ARND (Alcohol Related
Neuro-developmental Disorders)
ARBD (Alcohol Related Birth Defects)
