Reciprocal relations between positive alcohol expectancies and peer use on adolescent drinking: An accelerated autoregressive cross-lagged model using the NCANDA sample.

ABSTRACT: Positive alcohol expectancies (PAE) and associating with drinking peers are reliable predictors of adolescent alcohol use. Knowledge of when and for whom these risk factors are most influential could enhance intervention effectiveness. Reciprocal relations between PAE and adolescent and peer alcohol use were examined between the ages of 13 and 18 in a sample (N = 566; 50% female) from the National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA), as well as sex differences in these associations. Associating with drinking peers prospectively predicted more frequent alcohol use for both sexes, although peer socialization was evident earlier for girls compared with boys. Higher PAE influenced later drinking in mid-adolescence, from age 14 to 16, for boys only. PAE influenced peer group selection for both sexes, although the influence was evident earlier in boys than girls. The relative impact of environmental risk factors for problematic alcohol use may vary over time and across developmental periods. These results suggest that prevention and treatment efforts for adolescent drinking can be improved by targeting age-appropriate risk factors. Early adolescent interventions may be best served by minimizing involvement with drinking peers and correcting normative beliefs of peer use. Among adolescent girls, early interventions focused on reducing peer influence may be most effective. Prevention and treatment programs aimed at addressing PAE would likely prove more effective for boys in mid- to late adolescence. (PsycINFO Database Record

Project description:Adolescent drinking is an important public health concern, one that is influenced by both genetic and environmental factors. The functional variant rs1229984 in alcohol dehydrogenase 1B (ADH1B) has been associated at a genome-wide level with alcohol use disorders in diverse adult populations. However, few data are available regarding whether this variant influences early drinking behaviors and whether social context moderates this effect. This study examines the interplay between rs1229984 and peer drinking in the development of adolescent drinking milestones.One thousand five hundred and fifty European and African American individuals who had a full drink of alcohol before age 18 were selected from a longitudinal study of youth as part of the Collaborative Study on the Genetics of Alcoholism (COGA). Cox proportional hazards regression, with G × E product terms in the final models, was used to study 2 primary outcomes during adolescence: age of first intoxication and age of first DSM-5 alcohol use disorder symptom.The minor A allele of rs1229984 was associated with a protective effect for first intoxication (HR = 0.56, 95% CI 0.41 to 0.76) and first DSM-5 symptom (HR = 0.45, 95% CI 0.26 to 0.77) in the final models. Reporting that most or all best friends drink was associated with a hazardous effect for first intoxication (HR = 1.81, 95% CI 1.62 to 2.01) and first DSM-5 symptom (HR = 2.17, 95% 1.88 to 2.50) in the final models. Furthermore, there was a significant G × E interaction for first intoxication (p = 0.002) and first DSM-5 symptom (p = 0.01). Among individuals reporting none or few best friends drinking, the ADH1B variant had a protective effect for adolescent drinking milestones, but for those reporting most or all best friends drinking, this effect was greatly reduced.Our results suggest that the risk factor of best friends drinking attenuates the protective effect of a well-established ADH1B variant for 2 adolescent drinking behaviors. These findings illustrate the interplay between genetic and environmental factors in the development of drinking milestones during adolescence.
