AbstractAlcohol consumption is highly prevalent amongst women of reproductive age. Given that approximately 50% of pregnancies are unplanned, alcohol has the potential to affect fetal development and program chronic disease in offspring. We examined the effect of an acute but moderate prenatal alcohol exposure (PAE) on glucose metabolism, lipid levels and dietary preference in adolescent and/or adult rat offspring. Pregnant Sprague-Dawley rats received an oral gavage of ethanol (1g/kg maternal body weight, n=9 dams) or an equivalent volume of saline (control, n=8 dams) at embryonic days 13.5 and 14.5. PAE resulted in a blood alcohol concentration of 0.05-0.06% 1h post-gavage in dams. Fasting blood glucose concentration was not affected by PAE in offspring at any age, nor were blood glucose levels during a glucose tolerance test (GTT) in 6-month old offspring (P>0.5). However, there was evidence of insulin resistance in PAE male offspring at 6 months of age, with significantly elevated fasting plasma insulin (P= 0.001), a tendency for increased first phase insulin secretion during the GTT and impaired glucose clearance following an insulin challenge (P= 0.007). This was accompanied by modest alterations in protein kinase B (AKT) signalling in adipose tissue. PAE also resulted in reduced calorie consumption by offspring compared to controls (P= 0.04). These data suggest that a relatively low-level, acute PAE programs metabolic dysfunction in offspring in a sex-specific manner. These results highlight that alcohol consumption during pregnancy has the potential to affect the long-term health of offspring.Key points summaryPrenatal alcohol exposure has the potential to affect fetal development and program chronic disease in offspring.Previous preclinical models typically use high, chronic doses of alcohol throughout pregnancy to examine effects on offspring, particularly on the brain and behaviour.In this study we use a rat model of moderate, acute, prenatal alcohol exposure to determine if this can be detrimental to maintenance of glucose homeostasis in adolescent and adult offspring.Although female offspring were relatively unaffected, there was evidence of insulin resistance in 6-month old male offspring exposed to prenatal alcohol, suggestive of a pre-diabetic state.This result suggests that even a relatively low-dose, acute exposure to alcohol during pregnancy can still program metabolic dysfunction in a sex-specific manner.

Abstract Complex trauma resulting from chronic maltreatment and prenatal alcohol exposure can significantly affect child development and academic outcomes. Children with histories of maltreatment and those with prenatal alcohol exposure exhibit remarkably similar central nervous system impairments. In this article, I will review the effects of each on the brain and discuss clinical implications for these populations of children.

Data on the relation between moderate prenatal alcohol exposure (PAE) and behavioral disorders are inconsistent, and this raises new questions. We examined (1) the association between moderate PAE and problem behaviors and (2) whether these associations differed by levels of socioeconomic status (SES), fetal smoke exposure, or exposure to environmental tobacco smoke (ETS). Data were taken from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) study. Parents evaluated children’s behaviors using the Strengths and Difficulties Questionnaire (SDQ). Results showed a slight, but insignificant, increase of problem behaviors in children with moderate PAE. In 3- to 6-year-olds, PAE had a stronger effect on hyperactivity/inattention in combination with fetal smoke exposure (odds ratio = 2.82), than did PAE alone. Effects were not stronger in low-SES children, but they were stronger in children with ETS. We conclude that moderate PAE might have adverse effects on neurodevelopment, with stronger effects in disadvantaged populations. To confirm our preliminary findings, further research should be conducted.
