Research

In 1973, fifty years ago, two physicians from the University of Washington, Dr. Kenneth Jones and Dr. David Smith, published their research on the effects of prenatal alcohol exposure on the developing fetus. This was the start of awareness of FAS (FASD) in the U.S.*  Since then, there have been thousands of research articles on FASD published in mainstream journals. A sample of this research, by topic, is listed below.  

​

*Paul Lemoine MD, a French pediatrician, published the first research on FAS in 1968.

Higher rates of alcohol related liver disease among women.

"This is a touchy topic," said Rachel Sayko Adams, a research associate professor at the Boston University School of Public Health. "There is no safe level of alcohol use," she said. "That's, like, new information that people didn't want to know." The World Health Organization and various studies have found that no amount of alcohol is safe for human health. Even light drinking has been linked to health concerns, like hypertension and coronary artery disease and an increased risk of breast and other cancers.

And when it does come up, said Stephanie Garbarino, a transplant hepatologist at Duke Health, it's often surprising how many patients are unaware how their drinking affects their health.

"Often, they didn't know there was anything wrong with what they're doing," she said. She is more frequently seeing younger patients with liver disease, including men and women in their 20s and 30s.

But women are also frequently the focus of gender-targeted advertising for alcoholic beverages. The growth of rosé sales and low-calorie wines, for example, has exploded in recent years. New research published by the International Journal of Drug Policy in February found that the "pinking of products is a tactic commonly used by the alcohol industry to target the female market."

When Canada published guidance in 2023 advising that drinking any more than two alcoholic beverages a week carried health risks, Koob sparked backlash when his comments to the Daily Mail suggested that U.S. guidelines might move in the same direction. The CDC report published in February suggested that an increase in alcohol taxes could help reduce excessive alcohol use and deaths.

FASD and sleep

Wilson, Donald, et al. Developmental alcohol exposure is exhausting: Sleep and the enduring consequences of alcohol exposure during development. Neurosci BioBehav Rev 2024 February 1 105567. 

doi: 10.1016/j.neubiorev.2024.105567.

Prenatal alcohol exposure is the leading nongenetic cause of human intellectual impairment. The long-term impacts of prenatal alcohol exposure on health and well-being are diverse, including neuropathology leading to behavioral, cognitive, and emotional impairments. Additionally negative effects also occur on the physiological level, such as the endocrine, cardiovascular, and immune systems. Among these diverse impacts is sleep disruption. In this review, we describe how prenatal alcohol exposure affects sleep, and potential mechanisms of those effects. Furthermore, we outline the evidence that sleep disruption across the lifespan may be a mediator of some cognitive and behavioral impacts of developmental alcohol exposure, and thus may represent a promising target for treatment.

FASD and stigma

Roozen, Sylvia, et al. Understanding the Social Stigma of Fetal Alcohol Spectrum Disorders: From Theory to Interventions. Foundations of Science (2022) 27:753–771 https://doi.org/10.1007/s10699-020-09676-y

Alcohol consumption during pregnancy can lead to fetal alcohol spectrum disorders (FASD). FASD is a spectrum of structural, functional, and neurodevelopmental problems with often lifelong implications, affecting communities worldwide. It is a leading preventable form of intellectual disabilities and therefore warrants effective prevention approaches. However, well-intended FASD prevention can increase stigmatization of individuals with FASD, women who consume or have consumed alcohol during pregnancy, and non-biolog- ical parents and guardians of individuals with FASD. This narrative review surveyed the literature on stigmatization related to FASD. Public stigma appears to be the most common form of stigma studied.

"Combining physicians' expertise with mothers' personal stories of lived experiences of FASDs directed at residents, who are more reflective and open at this phase of their careers, moved them from a fact-based to an empathy-based approach to learning that is critical to address the stigma surrounding the women who may be using alcohol or struggling with an AUD during pregnancy.Collaboration between national organizations allowed this intervention to be widely implemented across the country."

Alcohol effect on prenatal development - results of new high resolution imaging.

Meombe Mbolle A, Thapa S, Bukiya AN, Jiang H. High-resolution imaging in studies of alcohol effect on prenatal development. Adv Drug Alcohol Res. 2023;3:10790. doi: 10.3389/adar.2023.10790. Epub 2023 Feb 1. PMID: 37593366; PMCID: PMC10433240.

Alcohol is capable of easily and rapidly passing from the mother’s bloodstream via the placenta into the developing fetal circulation where it penetrates through blood-brain barrier, and targets multiple critical fetal organs. 

Here are some of the findings from this review of studies on high resolution imaging on effects of prenatal alcohol exposure :

​Based on a pregnancy cohort study from 8 metropolitan areas in the United States, it was found:

• every successive week of alcohol use led to an 8% increase in the risk of spontaneous abortion and did not correlate to the number of drinks consumed per week or to binge drinking.

• This underscores the significant fact that no known amount of alcohol is safe during pregnancy.

• Alcohol can directly target several mechanisms at different stages of gestation and enable teratogenic effects (birth defects)

Some of these  effects include:

• disruption of neuronal cell survival, growth, and growth pathways leading to cell death in the early gestation period

• brain cell abnormalites - microglial cells are considered immune sentinels that are capable of orchestrating a potent inflammatory response. The microglial cells account for 0.5–16.6% of the total cell population in the human brain

• alteration of cardiac repair cells cells  

• dysfunction of the hypothalamus-pituitary-adrenal (HPA) axis , responsible for managing stress and anxiety, fight or flight response

FASD and adaptive intelligence

Hammond, Leah, et al. Adaptive behavior, sleep, and physical activity in adolescents with fetal alcohol spectrum disorder. Research in Developmental Disabilities 131 (December 2022) 104366

• Adaptive behavior describes an individual’s capacity to manage their everyday needs and encompasses abilities such as communication, social skills, personal care, and community use. Adaptive behavior deficits reflect an important clinical feature in FASD and are included in current diagnostic guidelines.

• Adolescents with FASD displayed significant impairments to all domains of adaptive behavior and considerable sleep disturbance.

• Worse sleep was associated with older age and sleep-related breathing disturbances were associated with poorer social adaptive behavior.

• Participation in physical activity, particularly organized sport, was strongly associated with better adaptive behavior.

No benefits to moderate drinking

Moderate Drinking Has No Health Benefits, Analysis of Decades of Research Finds  

Roni Caryn Rabin NYT April 4, 2023 

The review found that the methodology of many previous studies was flawed... In more recent decades, wine — and particularly red wine — developed a reputation for having health benefits after news stories highlighted its high concentration of a protective antioxidant called resveratrol, which is also found in blueberries and cranberries. But the moderate alcohol hypothesis has come under increasing criticism over the years as the alcohol industry’s role in funding research has come to light, and newer studies have found that even moderate consumption of alcohol — including red wine — may contribute to cancers of the breast, esophagus and head and neck, high blood pressure and a serious heart arrhythmia called atrial fibrillation.

January 2022 The CDC  Alcohol Consumption and Binge Drinking During Pregnancy Among Adults Aged 18–49 Years United States, 2018–2020   

In the U.S. 1 in 7 pregnant adults reported drinking at least one alcoholic drink in the last 30 days, 5.2% reported binge drinking - four or more drinks on at least one occasion in the last 30 days. This is an increase of 2 percentage points from 2019 data, in which 11.5% of pregnancies were alcohol exposed. In New England (Region 1) the rate of reported alcohol use among pregnant adults was 1 in 6, 16.4%. This was the second highest rate in the country - Region 9 was 16.7%.
