Abstract
The objective of the study is to investigate whether episodic binge pattern of alcohol consumption during pregnancy is independently associated with child mental health and academic outcomes. Using data from the prospective, population-based Avon Longitudinal Study of Parents and Children (ALSPAC), we investigated the associations between binge patterns of alcohol consumption during pregnancy (≥4 drinks per day) and child mental health [as rated by both parent (n = 4,610) and teacher (n = 4,274)] and academic outcomes [based on examination results (n = 6,939)] at age 11 years. After adjusting for prenatal and postnatal risk factors, binge pattern of alcohol consumption (≥4 drinks in a day on at least one occasion) during pregnancy was associated with higher levels of mental health problems (especially hyperactivity/inattention) in girls at age 11 years, according to parental report. After disentangling binge-pattern and daily drinking, binge-pattern drinking was independently associated with teacher-rated hyperactivity/inattention and lower academic scores in both genders. Episodic drinking involving ≥4 drinks per day during pregnancy may increase risk for child mental health problems and lower academic attainment even if daily average levels of alcohol consumption are low. Episodic binge pattern of drinking appears to be a risk factor for these outcomes, especially hyperactivity and inattention problems, in the absence of daily drinking.Electronic supplementary materialThe online version of this article (doi:10.1007/s00787-014-0599-7) contains supplementary material, which is available to authorized users.

The objective of the study is to investigate whether episodic binge pattern of alcohol consumption during pregnancy is independently associated with child mental health and academic outcomes
Using data from the prospective, population-based Avon Longitudinal Study of Parents and Children (ALSPAC), we investigated the associations between binge patterns of alcohol consumption during pregnancy (C4 drinks per day) and child mental health [as rated by both parent (n = 4,610) and teacher (n = 4,274)] and academic outcomes [based on examination results (n = 6,939)] at age 11 years
After adjusting for prenatal confounding factors and disentangling binge-pattern and daily drinking, our findings suggest that a binge pattern of alcohol consumption during pregnancy (C4 drinks in a day) is independently associated with higher levels of hyperactivity and inattention problems and lower academic attainment at age 11 years (Table 4)
Summary
Episodic drinking involving C4 drinks per day during pregnancy may increase risk for child mental health problems and lower academic attainment even if daily average levels of alcohol consumption are low. Episodic binge pattern of drinking appears to be a risk factor for these outcomes, especially hyperactivity and inattention problems, in the absence of daily drinking. In a previous analysis of this population-based cohort, we found that a binge pattern of drinking during pregnancy was associated with adverse parent-rated mental health outcomes at ages 4 and 7 years, in girls [18]. We aim to investigate: (1) the impact of episodic binge-pattern drinking on mental health as rated by both parents and teachers and on academic achievement and (2) whether risk occurs independently of regular (daily) drinking
