Maternal heavy alcohol use during pregnancy is harmful to offspring's health and adjustment. However, findings from studies on lower levels of prenatal drinking are mixed; a few even predict positive cognitive and psychosocial outcomes. Given that alcohol is a neurotoxin and teratogen, scholars question developmental benefits and point to residual confounding as a potential explanation, particularly as light drinkers are positively selected with respect to health and socioeconomic status. Using prospective, intergenerational data from the nationally-representative Millennium Cohort Study (MCS) in the United Kingdom, we studied associations between mother's drinking during pregnancy and children's cognitive and psychosocial outcomes at ages 3, 5, 7, 11, and 14 years (n = 10,454). We included early life confounders (e.g., maternal education, health, smoking) and mother's cognitive ability, and assessed robustness of relationships across outcomes and alternate drinking classifications. Results of a series of multivariable regression models found no association between light drinking and cognitive and psychosocial outcomes up to and including the age of 14, after controlling for key confounders. Light drinking during pregnancy was linked to higher socioeconomic advantages (e.g., mothers' higher education, professional/managerial occupation, home ownership, cognitive scores), which together accounted for positive associations between light drinking and children's outcomes. Mother's cognitive ability was an especially important confounder. [ABSTRACT FROM AUTHOR]

Objective: Typologies of symptom development have been used to identify individuals with different symptom development in the externalizing and internalizing domains of child psychopathology separately despite the domains' high comorbidity and shared common etiologic risk. This study identified typologies of development jointly across the 2 symptom domains in childhood and investigated their associated antecedents with a specific focus on the comparisons between overall severity of symptoms and symptom expression in one or the other domain.Method: Latent class analysis identified groups based on emotional and behavioral symptoms assessed at 3, 5, 7, and 11 years in the UK Millennium Cohort Study (N = 15,439). Different sociodemographic, family structure and environment, birth, infancy, and early childhood antecedents were examined.Results: Five groups were identified: 1. low symptoms (57%), 2. moderate behavioral (21%), 3. moderate emotional (12.5%), 4. high emotional and moderate behavioral (5.5%), and 5. high behavioral and moderate emotional (4%). Higher symptoms were predicted by larger numbers of antecedents and risk factors compared with the low symptom group and compared with moderate and high levels of symptoms in either domain (groups 5 versus 2 and 4 versus 3). Comparisons of groups with similar overall symptom levels but different dominant symptom domain (groups 2 versus 3 and 4 versus 5) indicated that apart from gender and ethnicity, there were few unique antecedents of whether children mainly internalize or externalize their symptoms.Conclusion: It is possible and useful to define groupings or typologies jointly across externalizing and internalizing symptom development in childhood. Although numerous antecedents predict the experience of symptoms, there are few unique antecedents that differentiate individuals with similarly high levels of psychopathology expressed mainly as internalizing or externalizing symptoms. Identification of at-risk children and delivery of early intervention might benefit from a decreased focus on symptom domain with possible downstream effects through the life course for most common psychiatric disorders.
