Each of these risk factors for poor pregnancy outcome must be considered in evaluating the effects of prenatal alcohol use, because it is unclear whether alcohol effects occur independently or in interaction with risk factors such as an impoverished social environment. Of the 8,638 women self-identifying as pregnant, 2,659 women identified as being in the first trimester, 3,112 in the second trimester, and 2,759 in the third trimester. Most were employed full-time (42.24%), earned either between $20,000\u201349,999 (30.64%) or over $75,000 per year (31.24%), reported being in \u201cvery good\u201d health (38.60%), and lived in a large metro area (53.96%). A majority of the sample took the survey in English (94.50%), had health insurance (92.13%), and did not receive government programs (70%). A small portion of the sample endorsed a history of criminal justice involvement (i.e., being arrested and booked; 13.41%), had past year mental health treatment (12.88%), and had a lifetime history of MDD (14.07%).<\/p>\n
In order to avoid additional stress on experimental animals, a different subset of pregnant dams was used for determination of blood ethanol concentrations (BECs), with tail-bloods collected every 2 h over a 12-h period. One possible explanation for these results is that Streissguth\u2019s sample includes both individuals with FAS and FAE, a less severe PAE diagnosis, while Rangmar\u2019s includes only adults with FAS. Both Fast & Conry and Streissguth et al., have pointed out that higher IQ is not protective when considering difficulties with the legal system and the odds ratios examining IQ as a predictor of these outcomes in Streissguth\u2019s study support this assertion. Inclusion of more participants who were less affected by PAE (and a large proportion with IQs over 70) in the Streissguth study is likely to have contributed to the higher reports of criminal behavior. Abel and Sokol (1987) estimated that approximately 6 percent of the offspring of alcoholic women have FAS, although for offspring born after an FAS sibling, the risk is very high (70 percent) (Abel 1988). The high probability that all subsequent offspring will be affected after an initial case means that some consequence of chronic alcoholism in addition to alcohol exposure must lead to the higher rate of FAS among offspring born later.<\/p>\n
In the same study, levels of cytokine IL-2, IL-1\u03b2, and TNF-\u03b1 in the hypothalamus of the PAE group on postnatal day 8 were lower compared to controls. Increased levels of TNF-\u03b1 in a developing brain can be neurotoxic by inducing oligodendrocyte apoptosis and myelination impairments in vitro and disturbing the blood\u2013brain barrier in vivo 69,70. Likewise, IL-1\u03b2 and IL-2 overexpression in vitro has shown oligodendrocyte toxicity and apoptosis induction in brain 71,72. Prenatal alcohol exposure (PAE) can have immediate and long-lasting toxic and teratogenic effects on an individual\u2019s development and health. As a toxicant, alcohol can lead to a variety of physical and neurological anomalies in the fetus that can lead to behavioral and other impairments which may last a lifetime.<\/p>\n
The outreach staff members discussed the study with potential participants and obtained consent using the IRB-approved form and procedure. Interviews or questionnaires were read to adults who were not able to read well enough to comprehend the questions themselves. Blood and urine samples were obtained during the medical evaluation so tests related to substance use could be completed. Grouping by cognitive status for nondysmorphic adults was based on the full-scale IQ score (WASI, Wechsler, 1999) obtained during the neurocognitive testing session. Effects of PAE continue into early adulthood and affect mental health problems, substance use, and interactions with the legal system.<\/p>\n

The relationship between prenatal exposure and growth deficits is linear (i.e., the greater the prenatal alcohol exposure, the more pronounced the effect on postnatal growth). Smith and colleagues (1986) also found that the duration of exposure, in addition to amount, affected birth weight. There is no safe amount or time of alcohol consumption during pregnancy; however, many women drink while pregnant placing themselves and their fetuses at risk for alcohol-related health complications. Understanding the impact of SDoH across pregnancy will elucidate important information to reduce rates of prenatal alcohol exposure. Prenatal alcohol exposure is a leading preventable cause of birth defects and neurodevelopmental disorders in the United States. Women who need help to stop drinking alcohol can talk to their health care provider about treatment options.<\/p>\n

Among exposed offspring who do not have FAS, deficits are seen in the same pattern, although they may be of smaller magnitude and do not affect all three systems in each person. Therefore, the effects of prenatal alcohol exposure range over a continuum from fully developed FAS to the milder constellation of fetal alcohol effects. Children with FAS are small for their age (Streissguth et al. 1991)\u2014indeed, such smallness is one of the criteria for diagnosis, although growth deficits also are found among children who were exposed to alcohol during pregnancy but do not fulfill the full criteria for FAS. In the MHPCD project, these growth deficits are symmetrical, affecting height, weight, and head circumference to the same degree, and remain significant through age 10.<\/p>\n
They found that, although the intake of absolute alcohol was equivalent in the two groups, 2.7 percent of the upper middle class mothers had a child with FAS, compared with 40.5 percent of the lower class mothers. There is evidence that drinking during pregnancy is related to pre-pregnancy drinking patterns; women who report drinking before pregnancy have been shown to be four times as likely to drink during pregnancy and twice as likely to binge drink during this time 25. Similarly, women who endorsed binge drinking at least three months prior to pregnancy were over eight times more likely to consume any alcohol while pregnant and almost 40 times more likely to continue binge drinking while pregnant 25. Epidemiological data shows significant increases in drinking among women of reproductive age, including heightened binge drinking in women under 25 years old and those not graduating high school 7, 26, 27.<\/p>\n
If you are pregnant and can’t stop drinking alcohol, ask your obstetrician, primary care doctor or other healthcare professional for help. A social worker can direct you to community programs that offer help, for example, Alcoholics Anonymous. Alcohol exposure during pregnancy can result in FASD by interfering with development of the baby\u2019s brain and other critical organs and physiological functions.<\/p>\n
