- Background: Non-European international adoptees in Sweden were shown to have a three-to fourfold higher risk of suicidal behaviour in youth during 1986-1995 compared with the general population. The aim of this study was to investigate whether this high risk persists beyond youth and in later cohorts.Methods: A register study of Swedish national cohorts born 1972-86 including 20 625 non-European international adoptees, and comparison populations of 10 915 non-European immigrants and 1 435 167 Swedish born was performed. The study population was followed from age 18 between 1991 and 2016, with suicide and hospital admissions due to suicide attempt as outcomes. Poisson regression models of person time in the study, adjusted for gender and household income at age 17, were fitted to calculate relative risks (RR).Findings: Adjusted RR for suicide in non-European international adoptees was high at age 18-22, 2.74 (95% C. I. 1.95-3.86), but decreased gradually to age 33-43 when the risk was similar to Swedish-born. Adjusted RR for suicide attempts in international adoptees was 2.33 (2.15-2.52) at age 18-22, decreased slightly with older age, but remained higher than Swedish born in all age-classes. Risks for both outcomes were greatest, around three times higher compared with the Swedish-born in the oldest birth cohorts of non-European international adoptees, born 1972-76. Risks for both suicidal outcomes increased with higher age at adoption.Interpretation: The risk of suicidal behaviour in non-European international adoptees in Sweden decreases with age and is lower in later birth cohorts and in infant adoptions.

- Several investigators have reported an increased frequency of attention/hyperactivity symptoms in international adoptees, though population-based studies are lacking. In this national cohort study, we aimed to determine the prevalence of ADHD medication in international adoptees in Sweden, in comparison to the general population. A further purpose was to study gender, age at adoption and region of origin as predictors of ADHD medication in international adoptees. The study population consisted of all Swedish residents born in 1985-2000 with Swedish-born parents, divided into 16,134 adoptees, and a comparison population of 1,326,090. ADHD medications were identified in the Swedish Prescribed Drug Register during 2006. Logistic regression was used to calculate the odds ratios. The rates of ADHD medication were higher in international adoptees than in the comparison population for both boys (5.3 vs. 1.5% for 10-15-year olds) and girls (2.1 vs. 0.3% for 10-15-year olds). International adoptees from all regions of birth more often consumed ADHD medication compared with the majority population, but the age and sex adjusted odds ratios were particularly high for adoptees from Eastern Europe, Middle East/Africa and Latin America. Adjusting for maternal education and single parenthood increased the odds ratios even further. The risk also increased with higher age at adoption. Adoptees from Eastern Europe have a very high risk for ADHD medication. A structured identification and support programme should be tailored for this group. Adoptees from other regions have a more moderately increased risk, which should be communicated to adoptive parents and to professionals who care for adoptees in their clinical practice.
