Binge-drinking ‘may not hurt the unborn’
Reported November 14, 2007
PREGNANT women can indulge in binge-drinking without doing any harm to their unborn child, new research suggests.
Oxford Universitys Jane Henderson and Ron Gray, along with the Danish researcher Ulrik Kesmodel from the University of Aarhus, argued that there was not enough evidence linking alcohol to fetal problems.
In their Systematic review of the fetal effects of prenatal binge drinking report published in the Journal of Epidemiology & Community Health, the researchers said that they examined thousands of papers on the subject.
A number of studies have linked heavy drinking on a regular basis during pregnancy to stunted growth, birth defects and brain development problems.
Less clear is the effect of occasional binge drinking, which amounted to about five drinks in one session in the studies Mr Gray and his team reviewed.
The researchers initially identified more than 3500 scientific papers between 1970 and 2005 looking at pregnancy and alcohol, which they winnowed down to 14 focusing on binge-drinking.
They found little substantive evidence binge drinking once in a while caused problems such as miscarriage, stillbirth, abnormal birth weight, or birth defects such as fetal alcohol syndrome.
But one study suggested binge-drinking could damage brain development resulting in reduced verbal IQ, learning problems and poorer academic performance.
“However, this study only counted women as bingers if they binged throughout pregnancy, not just on a single occasion,” the researchers wrote.
Animal studies had shown harmful effects from binge-drinking, which meant pregnant women should still take care no matter how much they consumed, Mr Gray said.
At the same time, until researchers had more evidence, women who binge-drink on occasion should not fret unnecessarily about potential harm they were causing to their fetuses, he said.
“When pregnant women report isolated episodes of binge-drinking in the absence of a consistently high daily alcohol intake, as is often the case, it is important to avoid inducing unnecessary anxiety as, at present, the evidence of risk seems minimal,” the researchers wrote.
Adelaide-based National Organisation for Fetal Alcohol Syndrome and Related Disorders (NOFASARD), pregnant women should not drink at all, let alone go on a binge.
The alcohol will reach your unborn baby within one minute and she/he will have exactly the same blood alcohol content as you do (and) the alcohol also stays in your baby longer than it does in you, the NOFASARD said.
Your babys brain is developing before you are sure you are pregnant, the whole way through your pregnancy and continues to develop after it has been born.
Because researchers are not sure how much alcohol might cause harm most say its safest not to drink any alcohol during this time.
