Index. décimale : PER Périodiques Résumé : Individuals diagnosed with autism often describe that they process sensory information differently from others, and many experience sensory issues as problematic. For instance, an increased sensitivity to smells or sounds can make participating in social settings challenging. While sensory issues are now part of the diagnostic criteria for autism, they also co-occur with other psychiatric diagnoses such as attention deficit hyperactivity disorder and anxiety disorders. It is unclear to what extent the relationship between autism and alterations in sensory processing are due to genetics or environment. In addition, more research is needed on how autism, as compared to other diagnoses, is associated with sensory issues. Using a twin study, we found that genetic factors influenced self-reported reactivity to sensory stimuli in autism while environmental factors influenced other sensory issues (e.g. difficulties in detecting or differentiating sensory input). Hence, sensory hyper-reactivity might be an early onset core feature of autism, while other domains of alterations in sensory processing might develop later, influenced by the environment. Moreover, autism was more strongly associated with sensory issues related to increased sensitivity/reactivity as compared to other psychiatric diagnoses. However, attention deficit hyperactivity disorder was more strongly related to deficits in detecting/differentiating sensory stimuli and with an increased drive to seek sensory input. Our results indicate that sensory issues are not specific to autism, but that some aspects of altered sensory processing are more relevant for autism than for other diagnoses.

Birth weight as an independent predictor of ADHD symptoms: a within-twin pair analysis / Erik PETTERSSON in Journal of Child Psychology and Psychiatry, 56-4 (April 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-4 (April 2015) . - p.453-459 Titre : Birth weight as an independent predictor of ADHD symptoms: a within-twin pair analysis Type de document : Texte imprimé et/ou numérique Auteurs : Erik PETTERSSON, Auteur ; Arvid SJÖLANDER, Auteur ; Catarina ALMQVIST, Auteur ; Henrik ANCKARSATER, Auteur ; Brian M. D'ONOFRIO, Auteur ; Paul LICHTENSTEIN, Auteur ; Henrik LARSSON, Auteur Article en page(s) : p.453-459 Langues : Anglais (eng) Mots-clés : ADHD  DSM  birth weight  behavioral genetics  environmental influences Index. décimale : PER Périodiques Résumé : Background Studies have found an association between low birth weight and ADHD, but the nature of this relation is unclear. First, it is uncertain whether birth weight is associated with both of the ADHD dimensions, inattentiveness and hyperactivity-impulsivity. Second, it remains uncertain whether the association between birth weight and ADHD symptom severity is confounded by familial factors. Method Parents of all Swedish 9- and 12-year-old twins born between 1992 and 2000 were interviewed for DSM-IV inattentive and hyperactive-impulsive ADHD symptoms by the Autism – Tics, AD/HD and other Comorbidities (A-TAC) inventory (N = 21,775 twins). Birth weight was collected prospectively through the Medical Birth Registry. We used a within-twin pair design to control for genetic and shared environmental factors. Results Reduced birth weight was significantly associated with a mean increase in total ADHD (? = ?.42; 95% CI: ?.53, ?.30), inattentive (? = ?.26; 95% CI: ?.33, ?.19), and hyperactive-impulsive (? = ?.16; 95% CI: ?.22, ?.10) symptom severity. These results imply that a change of one kilogram of birth weight corresponded to parents rating their child nearly one unit higher (going from “no” to “yes, to some extent” on a given symptom) on the total ADHD scale. These associations remained within pairs of MZ and DZ twins, and were also present when restricting the analyses to full term births. Conclusions There is an independent association between low birth weight and all forms of ADHD symptoms, even after controlling for all environmental and genetic confounds shared within twin pairs. These results indicate that fetal growth restriction (as reflected in birth weight differences within twin pairs) and/or the environmental factors which influence it is in the casual pathway leading to ADHD.

Contribution of genes and environment to the longitudinal association between childhood impulsive-aggression and suicidality in adolescence / Massimiliano ORRI in Journal of Child Psychology and Psychiatry, 61-6 (June 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-6 (June 2020) . - p.711-720 Titre : Contribution of genes and environment to the longitudinal association between childhood impulsive-aggression and suicidality in adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Massimiliano ORRI, Auteur ; Marie-Claude GEOFFROY, Auteur ; Gustavo TURECKI, Auteur ; Bei FENG, Auteur ; Mara BRENDGEN, Auteur ; Frank VITARO, Auteur ; Ginette DIONNE, Auteur ; Stéphane PAQUIN, Auteur ; Cédric GALERA, Auteur ; Johanne RENAUD, Auteur ; Richard E.

The objective was to determine the contribution of genes and environment to the association between childhood impulsive-aggression and serious suicidal ideation/attempt in young adulthood. METHODS: N = 862 twins (435 families) from the Quebec Newborn Twin Study were followed up from birth to 20 years. Repeated measures of teacher-assessed impulsive-aggression were modeled using a genetically informed latent growth model including intercept and slope parameters reflecting individual differences in the baseline level (age 6 years) and in the change (increase/decrease) of impulsive-aggression during childhood (6 to 12 years), respectively. Lifetime suicidality (serious suicidal ideation/attempt) was self-reported at 20 years. Associations of impulsive-aggression intercept and slope with suicidality were decomposed into additive genetic (A) and unique environmental (E) components. RESULTS: Additive genetic factors accounted for an important part of individual differences in impulsive-aggression intercept (A = 90%, E = 10%) and slope (A = 65%, E = 35%). Genetic (50%) and unique environmental (50%) factors equally contributed to suicidality. We found that 38% of the genetic factors accounting for suicidality were shared with those underlying impulsive-aggression slope, whereas 40% of the environmental factors accounting for suicidality were shared with those associated with impulsive-aggression intercept. The genetic correlation between impulsive-aggression slope and suicidality was 0.60, p = .027. CONCLUSIONS: Genetic and unique environmental factors underlying suicidality significantly overlap with those underlying childhood impulsive-aggression. Future studies should identify putative genetic and environmental factors to inform prevention.

Food fussiness and food neophobia share a common etiology in early childhood / Andrea D. SMITH in Journal of Child Psychology and Psychiatry, 58-2 (February 2017)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 58-2 (February 2017) . - p.189-196 Titre : Food fussiness and food neophobia share a common etiology in early childhood Type de document : Texte imprimé et/ou numérique Auteurs : Andrea D. SMITH, Auteur ; Moritz HERLE, Auteur ; Alison FILDES, Auteur ; Lucy COOKE, Auteur ; Silje STEINSBEKK, Auteur ; Clare H. LLEWELLYN, Auteur Année de publication : 2017 Article en page(s) : p.189-196 Langues : Anglais (eng) Mots-clés : Eating behavior  twin design  behavioral genetics  food fussiness  food neophobia Index. décimale : PER Périodiques Résumé : Background ‘Food fussiness’ (FF) is the tendency to be highly selective about which foods one is willing to eat, and emerges in early childhood; ‘food neophobia’ (FN) is a closely related characteristic but specifically refers to rejection of unfamiliar food. These behaviors are associated, but the extent to which their etiological architecture overlaps is unknown. The objective of this study was to quantify the relative contribution of genetic and environmental influences to variation in FF and FN in early childhood; and to establish the extent to which they share common genetic and environmental influences. Method Participants were 1,921 families with 16-month-old twins from the Gemini birth cohort. Parents completed the Child Eating Behaviour Questionnaire which included three FF items and four FN items. Bivariate quantitative genetic modeling was used to quantify: (a) genetic and environmental contributions to variation in FF and FN; and (b) the extent to which genetic or environmental influences on FF and FN are shared across the traits. Results Food fussiness and FN were strongly correlated (r = .72, p < .001). Proportions of variation in FF were equally explained by genetic (.46; 95% CI: 0.41–0.52) and shared environmental influences (.46; 95% CI: 0.41–0.51). Shared environmental effects accounted for a significantly lower proportion of variation in FN (.22; 95% CI: 0.14–0.30), but genetic influences were not significantly different from those on FF (.58, 95% CI: 0.50–0.67). FF and FN largely shared a common etiology, indicated by high genetic (.73; 95% CI: 0.67–0.78) and shared environmental correlations (.78; 95% CI: 0.69–0.86) across the two traits. Conclusions Food fussiness and FN both show considerable heritability at 16 months but shared environmental factors, for example the home environment, influenced more interindividual differences in the expression of FF than in FN. FF and FN largely share a common etiology.
