TUESDAY, June 18 (HealthDay News) -- Children of women who drink moderate amounts of alcohol while pregnant don't appear to have any neurodevelopmental problems when it comes to balance, a new British study suggests.

Researchers assessed the long-term health impact of drinking while pregnant by testing roughly 7,000 10-year-olds on their balancing abilities, a method that offers a reliable reflection of fetal neurodevelopment. For the study, "moderate" alcohol consumption was defined as between three to seven glasses of alcohol a week.

The research team cautioned, however, that other variables, such as maternal wealth and education, might have influenced the findings.

The bottom line, according to study co-author John Mcleod, is that "[there's] certainly no evidence that moderate alcohol use by pregnant mums is good for their kids, and [there are] reasons to be cautious about other messages around 'benefits' of moderate alcohol use by pregnant mums. But equally, [there's] no strong evidence for important harmful effects."

Macleod, chair of clinical epidemiology and primary care with the School of Social and Community Medicine at the University of Bristol, and his colleagues discuss their findings in the June 17 online edition of BMJ Open.

The research comes on the heels of another British study, released in April, which reported no connection between "light" drinking (one to two drinks per week) during pregnancy and increased risk for mental defects among children at the age of 7.

For the new study, the researchers focused on 6,915 children from southwest England who had participated in the larger Avon Longitudinal Study of Parents and Children.

The team first analyzed maternal drinking habits self-reported at both the 18-week mark of pregnancy and then again when the children were 4 years old.

The vast majority of mothers -- 70 percent -- said they drank no alcohol during pregnancy, while 25 percent said they had consumed drinks in the range of "low" (one to two per week) to "moderate" amounts on a weekly basis. Among such drinkers, one in seven had actually engaged in "binge drinking," meaning at least four glasses of alcohol at a sitting.
