Exploring the possibility of parents’ broad internalizing phenotype acting through passive gene–environment correlations on daughters’ disordered eating / Shannon M. O’CONNOR in Development and Psychopathology, 34-5 (December 2022)
[article]
Titre : Exploring the possibility of parents’ broad internalizing phenotype acting through passive gene–environment correlations on daughters’ disordered eating Type de document : Texte imprimé et/ou numérique Auteurs : Shannon M. O’CONNOR, Auteur ; Megan MIKHAIL, Auteur ; Carolina ANAYA, Auteur ; Leora L. HALLER, Auteur ; S. Alexandra BURT, Auteur ; Matt MCGUE, Auteur ; William G. IACONO, Auteur ; Kelly L. KLUMP, Auteur Article en page(s) : p.1744-1755 Langues : Anglais (eng) Mots-clés : Disordered eating eating disorders family twin study internalizing Index. décimale : PER Périodiques Résumé : Twin studies demonstrate significant environmental influences and a lack of genetic effects on disordered eating before puberty in girls. However, genetic factors could act indirectly through passive gene “environment correlations (rGE; correlations between parents’ genes and an environment shaped by those genes) that inflate environmental (but not genetic) estimates. The only study to explore passive rGE did not find significant effects, but the full range of parental phenotypes (e.g., internalizing symptoms) that could impact daughters’ disordered eating was not examined. We addressed this gap by exploring whether parents’ internalizing symptoms (e.g., anxiety, depressive symptoms) contribute to daughters’ eating pathology through passive rGE. Participants were female twin pairs (aged 8 “14 years; M = 10.44) in pre-early puberty and their biological parents (n = 279 families) from the Michigan State University Twin Registry. Nuclear twin family models explored passive rGE for parents’ internalizing traits/symptoms and twins’ overall eating disorder symptoms. No evidence for passive rGE was found. Instead, environmental factors that create similarities between co-twins (but not with their parents) and unique environmental factors were important. In pre-early puberty, genetic factors do not influence daughters’ disordered eating, even indirectly through passive rGE. Future research should explore sibling-specific and unique environmental factors during this critical developmental period.
