Advancing paternal age and offspring violent offending: A sibling-comparison study / Ralf KUJA-HALKOLA in Development and Psychopathology, 24-3 (August 2012)

D'ONOFRIO, Auteur ; Niklas LANGSTROM, Auteur ; Paul LICHTENSTEIN, Auteur Année de publication : 2012 Article en page(s) : p.739-53 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Children born to older fathers are at higher risk to develop severe psychopathology (e.g., schizophrenia and bipolar disorder), possibly because of increased de novo mutations during spermatogenesis with older paternal age. Because severe psychopathology is correlated with antisocial behavior, we examined possible associations between advancing paternal age and offspring violent offending. Interlinked Swedish national registers provided information on fathers' age at childbirth and violent criminal convictions in all offspring born from 1958 to 1979 (N = 2,359,921). We used ever committing a violent crime and number of violent crimes as indices of violent offending. The data included information on multiple levels; we compared differentially exposed siblings in within-family analyses to rigorously test causal influences. In the entire population, advancing paternal age predicted offspring violent crime according to both indices. Congruent with a causal effect, this association remained for rates of violent crime in within-family analyses. However, in within-family analyses, we found no association with ever committing a violent crime, suggesting that factors shared by siblings (genes and environment) confounded this association. Life-course persistent criminality has been proposed to have a partly biological etiology; our results agree with a stronger biological effect (i.e., de novo mutations) on persistent violent offending.

METHODS: Longitudinal cohort study based on 1,855 youths was clinically assessed for NSSI and SA, and followed up (from December, 2011 to December 2013) for the outcomes; diagnosed self-injury, alcohol/substance use disorder, and psychiatric inpatient care data derived from Swedish registers. Hazard ratios (HRs) and 95% confidence intervals (CIs) of the outcomes were estimated with Cox regressions, and additionally adjusted for the potential effect of sex and the number of clinical assessments. NSSI and SA were treated as time-varying covariates. RESULTS: Youths with NSSI had elevated risks of all outcomes, compared with youths without NSSI or SA; the HR was 2.3, 95% confidence interval [1.6, 3.4] for self-injury, 1.4 [0.9, 2.1] for alcohol/substance use disorder, and 1.3 [1.0, 1.7] for psychiatric inpatient care. Youths with SA displayed higher risks for the outcomes than the NSSI group; the HR was 5.5 [2.4, 12.6] for self-injury, 2.0 [0.9, 4.4] for alcohol/substance use disorder, and 2.6 [1.5, 4.5] for psychiatric inpatient care. Youths with both NSSI and SA showed similar risks as youths with SA; HR 4.1 [2.0, 8.3] for self-injury, 2.0 [1.1, 4.1] for alcohol/substance use disorder, but a higher risk of psychiatric inpatient care; HR 5.0 [3.1, 7.9]. All results remained virtually unchanged in the adjusted analyses. CONCLUSIONS: Youths with NSSI and/or SA had higher risks for subsequent adverse clinical outcomes. These excess risks were more pronounced among youths with SA and youths with both NSSI and SA, and the risk for psychiatric inpatient care was particularly high in youths with both NSSI and SA. Our findings suggest that early interventions for youths with NSSI or SA should not exclusively focus on suicide prevention, but also consider the risk of subsequent alcohol/substance use disorder.

Associations between conduct problems in childhood and adverse outcomes in emerging adulthood: a longitudinal Swedish nationwide twin cohort / Paul LICHTENSTEIN in Journal of Child Psychology and Psychiatry, 61-7 (July 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-7 (July 2020) . - p.798-806 Titre : Associations between conduct problems in childhood and adverse outcomes in emerging adulthood: a longitudinal Swedish nationwide twin cohort Type de document : Texte imprimé et/ou numérique Auteurs : Paul LICHTENSTEIN, Auteur ; Martin CEDERLÖF, Auteur ; Sebastian LUNDSTROM, Auteur ; Brian M.

METHODS: Participants were 18,649 twins from the Child and Adolescent Twin Study in Sweden. At age 9/12, parents rated their children on eight conduct problems. Adverse outcomes were retrieved from national registers in emerging adulthood (median follow-up time = 9.2 years), including diagnoses of six psychiatric disorders, prescriptions of antidepressants, suicide attempts, criminality, high school ineligibility, and social welfare recipiency. We estimated risk for the separate outcomes and examined if conduct problems predicted an internalizing factor above and beyond a general comorbidity and an externalizing factor. We used twin analyses to estimate genetic and environmental contributions to these associations. RESULTS: On the average, each additional conduct symptom in childhood was associated with a 32% increased risk of the adverse outcomes in emerging adulthood (mean hazard ratio = 1.32; range = 1.16, 1.56). A latent childhood conduct problems factor predicted the internalizing factor in emerging adulthood (?(boys) = .24, standard error, SE = 0.03; ?(girls) = .17, SE = 0.03), above and beyond its association with the externalizing (?(boys) = 0.21, SE = 0.04; ?(girls) = 0.17, SE = 0.05) and general factors (?(boys) = 0.45, SE = 0.03; ?(girls) = 0.34, SE = 0.04). These associations were differentially influenced by genetic and environmental factors. CONCLUSIONS: It is important to monitor boys and girls with conduct problems not only for future externalizing problems, but also for future internalizing problems. Prevention of specific outcomes, however, might require interventions at different levels.

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.

However, a large-scale survey of psychiatric, somatic, and adverse social outcomes up to adulthood, which could aid in prioritizing and tailoring prevention, is lacking. It also remains to clarify how risks are modified by other parental factors. Methods Swedish population registers were linked to compare offspring having (N?=?24,788) and not having (N?=?247,880) a parent with bipolar disorder with respect to psychiatric diagnoses and psychotropic medication, birth-related and somatic conditions, social outcomes, accidents, suicide attempts, and mortality. Individuals were followed until age 18. We estimated the influence of lifetime parental psychiatric comorbidity, bipolar disorder subtype, and sex on outcomes. Results Children of parents with bipolar disorder had 2?3 times higher risks of all psychiatric diagnoses, except for bipolar disorder, for which the risk was 11-fold. Significantly increased risks were also found for several somatic conditions, low school grades, criminal behavior, victimization, accidents, and suicidal behavior. Adjusting for lifetime parental psychiatric comorbidity attenuated most associations. Offspring of a parent with bipolar disorder type 2 had statistically significantly higher risks of attention deficit hyperactivity disorder, respiratory tract conditions, and accidents compared with offspring of a parent with bipolar disorder type 1. Offspring of mothers with bipolar disorder had higher risks of several psychiatric diagnoses, respiratory tract conditions, low school grades, and accidents compared with offspring of fathers with bipolar disorder. Having two parents with bipolar disorder entailed the highest risks of psychiatric outcomes in offspring. Conclusions Early intervention and family support are particularly warranted for the offspring of a parent with bipolar disorder in the presence of lifetime parental psychiatric comorbidity, when the parent has bipolar disorder type 2, or when the mother or both parents have bipolar disorder.
