A recent study has pointed out that maternal binge drinking during pregnancy causes more damage to children born to older drinking mothers.
The presence and severity of Fetal Alcohol Spectrum Disorders (FASD) are influenced by factors beyond alcohol consumption.
The researchers studied the factors that may increase the risk of FASD - maternal age.
"In this study, we showed that older women were also likely to drink more often during their pregnancy than younger women. If older women drink more during pregnancy, their fetuses will be at greater risk for FASD." said Lisa M. Chiodo, of Wayne State University.
"Our clinical experience has shown that children born to older alcoholic mothers display greater cognitive-behavioral deficits and more physical anomalies than those born to younger alcoholic mothers," said Piyadasa W. Kodituwakku of the University of New Mexico.
"The moderating effect of maternal age on the degree of alcohol-induced damage can clearly be seen in children born to the same mother who continued to drink, particularly to binge drink.
"In these families, the younger children tend to exhibit more physical anomalies and greater cognitive deficits than older children," Kodituwakku said.
Chiodo and colleagues examined the effects of maternal age on measures of attention in 462 children (231 boys, 231 girls) born to inner-city women were recruited during pregnancy at a university antenatal clinic.
The researchers examined binge drinking, smoking, and the use of cocaine, marijuana and opiates among the mothers. At seven years of age, the children completed a Continuous Performance Test, and their teachers completed the Achenbach Teacher Report Form.
