breastfeeding should receive extra support to quit.
He said, Egbogu, “What we advise is that they should abstain from alcohol. That is the baseline. Normally, if a woman has not been taking alcohol, she will most likely not take it during pregnancy. So, you have a situation where most women may have been taking alcohol before getting pregnant.
“Alcohol affects every organ of the baby and might lead to a baby having a small head – microcephaly. It affects the heart, kidney, and liver of the baby.”
Mayo Clinic, an online health portal in an article published on its website noted that breastfed babies that are exposed to one drink a day might have impaired motor development and that alcohol could cause changes in their sleep patterns.
“Also, while folklore says that drinking alcohol improves milk production, studies show that alcohol actually decreases milk production and that the presence of alcohol in breast milk causes babies to drink about 20 per cent less breast milk.
“If you choose to drink, avoid breastfeeding until the alcohol has completely cleared from your breast milk. If you plan to drink alcohol, consider having a drink just after breastfeeding so that the alcohol begins to clear from your breast milk during the natural interval between breastfeeding sessions.
“Remember, breastfeeding is the optimal way to feed a newborn and is recommended until a baby is at least of age. If you choose to drink, plan carefully to avoid exposing your baby to alcohol”, Mayo Clinic stated.
Meanwhile, in research scarried out by the University of California – Riverside and published in ScienceDaily, it was found that infants’ exposure to alcohol through breast milk could have long-lasting effects on their brain and behavioural development.
According to the researchers, the reduction of body and brain weights may be explained by the gut’s inability to efficiently extract nutrients when alcohol is ingested.
Currently, the Centers for Disease Control and Prevention advise against maternal alcohol consumption during pregnancy and states that there is no known safe level of consumption.
Led by Kelly Huffman, a professor of Psychology at the university, the team said specifically, young mice that were exposed to alcohol during early development showed smaller body and brain growth, as well as decreased cortical lengths — a measure of brain size.
The researchers focused on lactational ethanol exposure, or LEE, and developed a novel postnatal alcohol exposure model in breastfeeding mice.
In the mouse model, the researchers said offspring were exposed to ethanol via nursing from ‘postnatal day (P) 6 through P20 (weaning)’, a period equivalent to infancy in humans.
They noted that compared to controls, LEE mice had reduced body and brain weights, as well as decreased neocortical lengths as weaning continuing through to early puberty (age P30).
“Brain weights were reduced in both ages for males, and at P20 for females; however, P30 female brain weights recovered to control levels. This discovery provides evidence towards sex-specific differences due to LEE”, they added.
The research showed that approximately 36 per cent of breastfeeding mothers in the United States consume alcohol.
In Canada and Australia, the numbers were noted to be 20 per cent and 60 per cent respectively.
Evidence also showed that women who consume alcohol during pregnancy are more likely to drink while breastfeeding, while many women who choose to abstain from drinking during pregnancy report drinking again shortly after giving birth.
Commenting on the report, the lead author, Prof. Huffman said, “The reduced body weights in both males and females at P20 and P30 are reflected in human studies in which children exposed to ethanol through contaminated breast milk have lower body weights and growth trajectories.
“A decrease in protein synthesis in the small intestine may block absorption of micro- and macronutrients.
“Thus, women should refrain from consuming alcohol during breastfeeding until more research can help recommend safe maternal practices in early infancy.
“We hope our work will increase public awareness of safe maternal practices’.
With regard to how the behavioural development of the LEE mice is affected, Huffman said behavioural tests her team performed on LEE mice suggested that they engage in higher risk-taking behaviour and show abnormal stress regulation and increased hyperactivity.
