I'm looking at a study that concluded that there is a risk involved with light drinking, at random (
https://pubs.niaaa.nih.gov/publications/arh341/86-91.pdf), and as expected, it's not serious, and they aknowledge it :
. First, alcohol consumption data typically are collected via selfreport
"I'm only drinking a glass of wine every week, I swear" say alcoholic mother #234
Now I'm looking at the data
Fetal demise occurring after 20 weeks gestation, or stillbirth, affects 6.22 of every 1,000 pregnancies in the United States each year
(...)
A study (Aliyu et al. 2008) of more than 600,000 human births found a statistically significant 40 percent increase in likelihood of stillbirth for women who consumed any amount of alcohol compared with those who did not consume alcohol at all.Data were further analyzed to examine the amount of alcohol consumption, and the increased risk was almost completely attributed to those who consumed five or more drinks per week.
I can't find the raw data, but I'm pretty sure that we'd notice that the drinking self-report from pregnant women isn't coherent at all with :
One in eight American adults, or 12.7 percent of the U.S. population, now meets diagnostic criteria for alcohol use disorder, according to the study.
I think the reason we don't say "it's okay to have a cup of Champagne at a birthday party, or at New Year's Eve Party or a glass of wine once a week at the sunday family reunion" to pregnant women is not because there is
any risk of doing it, but because a significant part of the population are alcoholic, and those people will understand that message as "business as usual, girl!"
I know the discussion was about small kids and not pregnancies, but in the absence of
any research, it's probably the best thing we have.
