Titre : Alcohol use polygenic risk score, social support, and alcohol use among European American and African American adults Type de document : Texte imprimé et/ou numérique Auteurs : Jinni SU, Auteur ; Sally I.

DICK, Auteur Article en page(s) : p.1763-1775 Langues : Anglais (eng) Mots-clés : COGA alcohol use gene-environment interaction polygenic scores social support Index. décimale : PER Périodiques Résumé : Alcohol use is influenced by genetic and environmental factors. We examined the interactive effects between genome-wide polygenic risk scores for alcohol use (alc-PRS) and social support in relation to alcohol use among European American (EA) and African American (AA) adults across sex and developmental stages (emerging adulthood, young adulthood, and middle adulthood). Data were drawn from 4,011 EA and 1,274 AA adults from the Collaborative Study on the Genetics of Alcoholism who were between ages 18-65 and had ever used alcohol. Participants completed the Semi-Structured Assessment for the Genetics of Alcoholism and provided saliva or blood samples for genotyping. Results indicated that social support from friends, but not family, moderated the association between alc-PRS and alcohol use among EAs and AAs (only in middle adulthood for AAs); alc-PRS was associated with higher levels of alcohol use when friend support was low, but not when friend support was high. Associations were similar across sex but differed across developmental stages. Findings support the important role of social support from friends in buffering genetic risk for alcohol use among EA and AA adults and highlight the need to consider developmental changes in the role of social support in relation to alcohol use.

Titre : The role of adolescent social relationships in promoting alcohol resistance: Interrupting the intergenerational transmission of alcohol misuse Type de document : Texte imprimé et/ou numérique Auteurs : Mallory STEPHENSON, Auteur ; Fazil ALIEV, Auteur ; Sally I. Chun KUO, Auteur ; Alexis C. EDWARDS, Auteur ; Gayathri PANDEY, Auteur ; Jinni SU, Auteur ; Chella KAMARAJAN, Auteur ; Danielle DICK, Auteur ; Jessica E. SALVATORE, Auteur Article en page(s) : p.1841-1855 Langues : Anglais (eng) Mots-clés : adolescence alcohol parenting peer relationships resistance Index. décimale : PER Périodiques Résumé : Genetic factors contribute to the intergenerational transmission of alcohol misuse, but not all individuals at high genetic risk develop problems. The present study examined adolescent relationships with parents, peers, and romantic partners as predictors of realized resistance, defined as high biological risk for disorder combined with a healthy outcome, to alcohol initiation, heavy episodic drinking, and alcohol use disorder (AUD). Data were from the Collaborative Study on the Genetics of Alcoholism (N = 1,858; 49.9% female; mean age at baseline = 13.91 years). Genetic risk, indexed using family history density and polygenic risk scores for alcohol problems and AUD, was used to define alcohol resistance. Adolescent predictors included parent-child relationship quality, parental monitoring, peer drinking, romantic partner drinking, and social competence. There was little support for the hypothesis that social relationship factors would promote alcohol resistance, with the exception that higher father-child relationship quality was associated with higher resistance to alcohol initiation ( $$\hat \beta $$ = â’0.19, 95% CI = â’0.35, â’0.03). Unexpectedly, social competence was associated with lower resistance to heavy episodic drinking ( $$\hat \beta $$ = 0.10, 95% CI = 0.01, 0.20). This pattern of largely null effects underscores how little is known about resistance processes among those at high genetic risk for AUD.

DICK, Auteur Article en page(s) : p.1865-1875 Langues : Anglais (eng) Mots-clés : adolescent externalizing gene-environment correlation genetic nurture parenting polygenic score Index. décimale : PER Périodiques Résumé : The purpose of this study was to examine possible pathways by which genetic risk associated with externalizing is transmitted in families. We used molecular data to disentangle the genetic and environmental pathways contributing to adolescent externalizing behavior in a sample of 1,111 adolescents (50% female; 719 European and 392 African ancestry) and their parents from the Collaborative Study on the Genetics of Alcoholism. We found evidence for genetic nurture such that parental externalizing polygenic scores were associated with adolescent externalizing behavior, over and above the effect of adolescents’ own externalizing polygenic scores. Mediation analysis indicated that parental externalizing psychopathology partly explained the effect of parental genotype on children’s externalizing behavior. We also found evidence for evocative gene-environment correlation, whereby adolescent externalizing polygenic scores were associated with lower parent “child communication, less parent “child closeness, and lower parental knowledge, controlling for parental genotype. These effects were observed among participants of European ancestry but not African ancestry, likely due to the limited predictive power of polygenic scores across ancestral background. These results demonstrate that in addition to genetic transmission, genes influence offspring behavior through the influence of parental genotypes on their children’s environmental experiences, and the role of children’s genotypes in shaping parent “child relationships.
