Titre : Maternal infection requiring hospitalization during pregnancy and attention-deficit hyperactivity disorder in offspring: a quasi-experimental family-based study Type de document : Texte imprimé et/ou numérique Auteurs : Y. GINSBERG, Auteur ; B. M. D'ONOFRIO, Auteur ; M. E. RICKERT, Auteur ; Q. A. CLASS, Auteur ; M. A. ROSENQVIST, Auteur ; Catarina ALMQVIST, Auteur ; P. LICHTENSTEIN, Auteur ; H.

However, infection is associated with social adversity, poor living conditions and other background familial factors. As such, there is a need to rule out whether the observed association between maternal IDP and ADHD might be attributed to such confounding. METHODS: This nationwide population-based cohort study using a family-based, quasi-experimental design included 1,066,956 individuals born in Sweden between 1992 and 2002. Data on maternal IDP (bacterial or viral) requiring hospitalization and ADHD diagnosis in offspring were gathered from Swedish National Registers, with individuals followed up through the end of 2009. Ordinary and stratified Cox regression models were used for estimation of hazard ratios (HRs) and several measured covariates were considered. Cousin- and sibling-comparisons accounted for unmeasured genetic and environmental factors shared by cousins and siblings. RESULTS: In the entire population, maternal IDP was associated with ADHD in offspring (HR = 2.31, 95% CI = 2.04-2.61). This association was attenuated when accounting for measured covariates (HR = 1.86, 95% CI = 1.65-2.10). The association was further attenuated when adjusting for unmeasured factors shared between cousins (HR = 1.52, 95% CI = 1.12-2.07). Finally, the association was fully attenuated in sibling comparisons (HR = 1.03, 95% CI = 0.76-1.41). CONCLUSIONS: This study suggests that the association between maternal IDP and offspring ADHD is largely due to unmeasured familial confounding. Our results underscore the importance of adjusting for unobserved familial risk factors when exploring risk factors for ADHD.

FEIN, Auteur Article en page(s) : p.2096-2102 Langues : Anglais (eng) Mots-clés : depression firearms gun violence longitudinal quasi-experimental Index. décimale : PER Périodiques Résumé : We tested whether exposure to gun or knife violence over two decades is a cause of depression in young adulthood using data from a nationally representative sample in the United States. The National Longitudinal Study of Adolescent to Adult Health is a sample of 20,745 adolescents, assessed in 1994-95 with follow-ups in 1995-1996 (n = 14,738), 2001-2002 (n = 15,197) and 2007-2008 (n = 15,701; 24 to 32 years old). At each wave, respondents reported exposure to gun or knife violence and symptoms of depression. Regression and sibling fixed effects analyses were conducted to test whether cumulative exposure to gun or knife violence was associated with depression. In fully adjusted models, greater cumulative exposure to gun or knife violence was associated with more symptoms of depression (b = 0.12, 95% C. I. = 0.05; 0.19, p < 0.01) and higher risk for clinically significant depression in young adulthood (OR = 1.07, 95% C. I. = 1.02; 1.13, p < 0.01). Results replicated in sibling fixed effects models (b = 0.21, 95% C. I. = 0.01; 0.42, p < 0.05). These quasi-experimental data suggest that exposure to gun or knife violence is a cause of depression in young adulthood.
