Polygenic and environmental influences on the course of African Americans' alcohol use from early adolescence through young adulthood / Jill A. RABINOWITZ in Development and Psychopathology, 32-2 (May 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-2 (May 2020) . - p.703-718 Titre : Polygenic and environmental influences on the course of African Americans' alcohol use from early adolescence through young adulthood Type de document : texte imprimé Auteurs : Jill A.

Participants (N = 436) were initially recruited for an elementary school-based prevention trial in a Mid-Atlantic city. Youths reported on the frequency of their past year alcohol use from ages 14-26. DNA was obtained from participants at age 21. Internalizing symptoms and antisocial behavior PRSs were created based on a genome-wide association study (GWAS) conducted by Benke et al. (2014) and Tielbeek et al. (2017), respectively. Parental monitoring and community disadvantage were assessed at age 12. Four classes of past year alcohol use were identified: (a) early-onset, increasing; (b) late-onset, moderate use; (c) low steady; and (d) early-onset, decreasing. In high community disadvantaged settings, participants with a higher internalizing symptoms PRS were more likely to be in the early-onset, decreasing class than the low steady class. When exposed to elevated community disadvantage, participants with a higher antisocial behavior PRS were more likely to be in the early-onset, increasing class than the early-onset, decreasing and late-onset, moderate use classes.

Violence exposure in an urban city: A GxE interaction with aggressive and impulsive behaviors / Rashelle J. MUSCI in Journal of Child Psychology and Psychiatry, 60-1 (January 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-1 (January 2019) . - p.72-81 Titre : Violence exposure in an urban city: A GxE interaction with aggressive and impulsive behaviors Type de document : texte imprimé Auteurs : Rashelle J. MUSCI, Auteur ; Amie F. BETTENCOURT, Auteur ; Danielle SISTO, Auteur ; Brion MAHER, Auteur ; Katherine E. MASYN, Auteur ; Nicholas S. IALONGO, Auteur Article en page(s) : p.72-81 Langues : Anglais (eng) Mots-clés : Aggression  genetics  molecular  violence Index. décimale : PER Périodiques Résumé : BACKGROUND: Previous research has demonstrated a reciprocal relationship between community violence exposure and disruptive behavior problems among youth. No study to date, however, has explored the potential interaction between violence exposure in early adolescence and genetics. METHODS: We explore the gene x environment interaction's impact on teacher-rated aggressive and impulsive behaviors. Violence exposure during the middle school years was assessed using self-report. Genetic data collection occurred in emerging adulthood. A polygenic score was created using findings from a conduct disorder symptomatology genome-wide association study. RESULTS: Three longitudinal classes of teacher reported aggressive and impulsive behavior were identified. We found a significant relationship between violence exposure and class membership. There was a significant GxE interaction, such that those with below average levels of the polygenic score and who were exposed to violence were more likely to be in the moderately high aggressive and impulsive class as compared to the no to low class. CONCLUSIONS: These findings highlight the influence of genetic risk together with violence exposure on adolescent problem behavior. Although youth may have little control over the environments in which they live, interventions can and should focus on helping all youth.
