Titre : Parental death during childhood and depression in young adults – a national cohort study Type de document : Texte imprimé et/ou numérique Auteurs : Lisa BERG, Auteur ; Mikael ROSTILA, Auteur ; Anders HJERN, Auteur Article en page(s) : p.1092-1098 Langues : Anglais (eng) Mots-clés : Childhood parental death adult depression longitudinal national cohort familial risk factors parental psychopathology social position Index. décimale : PER Périodiques Résumé : Background There are few prospective, population-based studies on childhood parental death and psychiatric disorders in adulthood, and previous findings are inconclusive. This study investigated the association between parental death from natural and external (suicides, accidents or homicides) causes before 18 years and the risk of clinical depression in young adults, in relation to age at loss and gender of both child and parent. Methods In this register-based study, a national cohort born in Sweden during 1973–1982 (n = 862,554) was followed with regard to hospital admissions and outpatient care for depression during 2006–2013. Multivariate Cox proportional hazards models were used to estimate the impact of parental death, taking sociodemographic and parental psychosocial covariates into account. Results Maternal death from natural causes was associated with a hazard ratio (HR) of outpatient care for depression of 1.19 [95% confidence interval (CI), 1.02–1.40] in men and 1.15 (1.01–1.31) in women, after adjustment for sociodemographic confounders, with similar effect sizes for paternal natural death. Death from external causes consistently had higher effect size compared with natural deaths, in particular in relation to risk of hospital admissions for depression where they were as high as HR 3.23 (2.38–4.38) for men, and 1.79 (1.30–2.47) for women after a loss of a mother. Losing a parent in preschool age, compared with losing a parent as a teenager, was associated with higher risks of both hospitalization (p = .006) and outpatient care (p = .001) for depression. Conclusions This study indicates that parental loss to death from natural causes during childhood is associated with a small increased risk of long-term consequences for psychological health. Children who lose their parents to death from external causes, that is suicides, accidents or homicides, and children losing a parent in young ages are, however, at particular risk and should be given priority in preventive interventions after parental loss.

Titre : Suicide attempts and severe psychiatric morbidity among former child welfare clients – a national cohort study Type de document : Texte imprimé et/ou numérique Auteurs : Bo VINNERLJUNG, Auteur ; Anders HJERN, Auteur ; Frank LINDBLAD, Auteur Année de publication : 2006 Article en page(s) : p.723–733 Langues : Anglais (eng) Mots-clés : Suicide psychiatric-morbidity foster-care adoption cohort-study Index. décimale : PER Périodiques Résumé : Background: Few large sample studies have examined psychiatric morbidity among former child welfare/protection clients. In this study, risks for suicide attempts and severe psychiatric morbidity in younger years were assessed for former child welfare clients in ten national birth cohorts, comparing them with general population peers and inter-country adoptees.
Methods: We used national register data for almost one million people: 22,305 former child welfare clients who had experienced interventions before their teens, 955,326 general population cohort peers and 12,240 inter-country adoptees. Multivariate Cox regression models were used to estimate risks of hospitalisation for suicide attempts and psychiatric disorders from age 13 to age 18–27.
Results: Former child welfare clients were in year of birth and sex standardised risk ratios (RRs) four to five times more likely than peers in the general population to have been hospitalised for suicide attempts. They were five to eight times more likely to have been hospitalised for serious psychiatric disorders in their teens, four to six times in young adulthood. High excess risks were also found for psychoses and depression. Individuals who had been in long-term foster care tended to have the most dismal outcome. Adjusting for birth parents' hospitalisations with a psychiatric diagnosis or for substance abuse, and for birth-home-related socio-economic factors, reduced excess risks to around twofold.
Conclusions: Irrespective of issues of causality, findings suggest that former child welfare/protection clients should be considered a high-risk group for suicide attempts and severe psychiatric morbidity. Results have substantial practice implications for mental health and social agencies serving this group in adolescence and/or young adulthood.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2005.01530.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=757
