[Show abstract][Hide abstract] ABSTRACT: The aim was to examine the effects of low to moderate maternal alcohol consumption and binge drinking in early pregnancy on children's attention at 5 years of age.
Prospective follow-up study.
Neuropsychological testing in four Danish cities 2003-2008.
A cohort of 1628 women and their children sampled from the Danish National Birth Cohort.
Participants were sampled based on maternal alcohol consumption during pregnancy. At 5 years of age, the children were tested with the recently developed Test of Everyday Attention for Children at Five (TEACh-5). Parental education, maternal IQ, maternal smoking in pregnancy, the child's age at testing, gender, and tester were considered core confounding factors, whereas the full model also controlled the following potential confounding factors: maternal binge drinking or low to moderate alcohol consumption, age, body mass index (BMI), parity, home environment, postnatal smoking in the home, child's health status, and indicators for hearing and vision impairments.
TEACh-5 attention scores.
There were no significant effects on test performance in children of mothers drinking up to 8 drinks per week compared with children of mothers who abstained, but there was a significant association between maternal consumption of 9 or more drinks per week and risk of a low overall attention score (OR 3.50, 95% CI 1.15-10.68). No consistent or significant associations were observed between binge drinking and attention test scores.
The findings suggest an effect of maternal consumption of 9 or more drinks per week on attention functions in children, but the study detected no effects of lower levels of maternal consumption and no consistent effects of maternal binge drinking.

[Show abstract][Hide abstract] ABSTRACT: It has been suggested that even mild exposure to alcohol, caffeine, smoking, and poor diet may have adverse long-term neurodevelopmental effects. In addition, there is evidence that timing of high exposures (e.g. binge drinking) can have particularly negative effects. This paper describes the design and implementation of The Lifestyle During Pregnancy Study addressing major methodological challenges for studies in this field. The study examines the effects of lifestyle during pregnancy on offspring neurodevelopment.
In 2003, we initiated a prospective follow-up of 1750 mother-child pairs, sampled on the basis of maternal alcohol drinking patterns from The Danish National Birth Cohort (DNBC), a study of 101,042 pregnancies enrolled 1997-2003. Data collection in the DNBC involved four prenatal and postnatal maternal interviews, providing detailed information on maternal alcohol drinking patterns before and during pregnancy, caffeine intake, smoking, diet, and other lifestyle, medical, and sociodemographic factors.
At the age of 5 years, the children and their mothers participated in a comprehensive assessment of neurobehavioural development focusing on global cognition, specific cognitive functions, and behaviour. Two new tests assessing attention and speed of information processing among children were developed, and data on important potential confounders such as maternal intelligence quotient, vision, and hearing abilities were collected. Efforts were made to standardise procedures and obtain high inter-rater reliability.
We expect that the study will illuminate the significance or lack of significance of maternal lifestyle during pregnancy and contribute to better understanding the effects of alcohol drinking during pregnancy at low to moderate consumption levels.
