- Aims Little is known regarding how the risk of suicide in refugees relates to their host country. Specifically, to what extent inter-country differences in structural factors between the host countries may explain the association between refugee status and subsequent suicide is lacking in previous literature. We aimed to investigate (1) the risk of suicide in refugees resident in Sweden and Norway, in general, and according to their sex, age, region/country of birth and duration of residence, compared with the risk of suicide in the respective majority host population; (2) if factors related to socio-demographics, labour market marginalisation (LMM) and healthcare use might explain the risk of suicide in refugees differently in host countries. Methods Using a nested case-control design, each case who died by suicide between the age of 18 and 64 years during 1998 and 2018 (17 572 and 9443 cases in Sweden and Norway, respectively) was matched with up to 20 controls from the general population, by sex and age. Multivariate-adjusted conditional logistic regression models yielding adjusted odds ratios (aORs) with 95% confidence intervals (95% CI) were used to test the association between refugee status and suicide. Separate models were controlled for factors related to socio-demographics, previous LMM and healthcare use. Analyses were also stratified by sex and age groups, by refugees' region/country of birth and duration of residence in the host country. Results The aORs for suicide in refugees in Sweden and Norway were 0.5 (95% CI 0.5-0.6) and 0.3 (95% CI 0.3-0.4), compared with the Swedish-born and Norwegian-born individuals, respectively. Stratification by region/country of birth showed similar statistically significant lower odds for most refugee groups in both host countries except for refugees from Eritrea (aOR 1.0, 95% CI 0.7-1.6) in Sweden. The risk of suicide did not vary much across refugee groups by their duration of residence, sex and age except for younger refugees aged 18-24 who did not have a statistically significant relative difference in suicide risk than their respective host country peers. Factors related to socio-demographics, LMM and healthcare use had only a marginal influence on the studied associations in both countries. Conclusions Refugees in Sweden and Norway had almost similar suicide mortality advantages compared with the Swedish-born and Norwegian-born population, respectively. These findings may suggest that resiliency and culture/religion-bound attitudes towards suicidal behaviour in refugees could be more influential for their suicide risk after resettlement than other post-migration environmental and structural factors in the host country.

- Aims: To study associations between intellectual disability (ID) and sexual and violent offending among individuals subject to pre-trial forensic psychiatric assessment. To investigate sentences following pre-trial forensic psychiatric assessment in offenders with and without ID.Methods: A population-based observational study using data from pre-trial forensic psychiatric assessments in Sweden (1997-2013), the Swedish National Crime Register and several other Swedish national registers. The study population consisted of 7450 offenders (87% men, 13% women) who were subject to forensic psychiatric assessment in 1997-2013, of whom 481 (6.5%) were clinically assessed as having ID.Results: ID offenders were more likely than non-ID offenders to have a sexual crime as an index crime [26.2 v. 11.5%, adjusted odds ratio (OR) 2.7, 95% confidence interval (CI) 2.02-3.58] as well as previous convictions regarding sexual offending (10.4 v. 5.6%, adj OR 2.3, 95% CI 1.70-3.12). These associations were restricted to male offenders; sexual offending was uncommon among women. Comorbid attention-deficit hyperactivity disorder reduced the association between ID and sexual offending (adj OR 2.7 v. 3.1, p = 0.017), while comorbid autism spectrum disorder had no significant influence on the association (adj OR 2.7 v. 3.0, p = 0.059). Violent crime was equally common among ID and non-ID offenders. Offenders with ID were more likely than non-ID offenders to be sentenced to forensic psychiatric care or community sanctions and measures (such as probation, conditional sentences or fines) than to prison; however, 15% of individuals who received an ID diagnosis during the forensic psychiatric assessment were sentenced to prison. Previous criminal convictions, concurrent antisocial personality disorders and substance use disorders were associated with a higher probability of a prison sentence among offenders with ID.Conclusions: Sexual crime is overrepresented among offenders with ID compared to offenders with other mental disorders than ID in forensic psychiatric contexts. ID offenders become subject to forensic psychiatric care and forensic psychiatric services need evidence-based treatment programmes for offenders with ID. In addition, there is a need for early intervention strategies suitable for disability services and special education schools, in order to address the complex needs of individuals with ID and prevent sexual and violent offending.

- Aims: Labour market marginalisation (LMM), i.e. severe problems in finding and keeping a job, is common among young adults with attention-deficit/hyperactivity disorder (ADHD). This study aimed to disentangle the extent of LMM as well as the heterogeneity in patterns of LMM among young adults with ADHD and what characterises those belonging to these distinct trajectories of LMM.Methods: This population-based register study investigated all 6287 young adults, aged 22-29 years, who had their first primary or secondary diagnosis of ADHD in Sweden between 2006 and 2011. Group-based trajectory (GBT) models were used to estimate trajectories of LMM, conceptualised as both unemployment and work disability, 3 years before and 5 years after the year of an incident diagnosis of ADHD. Odds ratios (ORs) with 95% confidence intervals (CIs) for the association between individual characteristics and the trajectory groups of LMM were estimated by multinomial logistic regression.Results: Six distinct trajectories of LMM were found: 'increasing high' (21% belonged to this trajectory group) with high levels of LMM throughout the study period, 'rapidly increasing' (19%), 'moderately increasing' (21%), 'constant low' (12%) with low levels of LMM throughout the study period, 'moderately decreasing' (14%) and finally 'fluctuating' (13%), following a reversed u-shaped curve. Individuals with the following characteristics had an increased probability of belonging to trajectory groups of increasing LMM: low educational level (moderately increasing: OR: 1.4; CI: 1.2-1.8, rapidly increasing: OR: 1.7; CI: 1.3-2.1, increasing high: OR: 2.9; CI: 2.3-3.6), single parents (moderately increasing: OR: 1.6; CI: 1.1-2.4, rapidly increasing: OR: 2.0; CI: 1.3-3.0), those born outside the European Union/the Nordic countries (rapidly increasing: OR: 1.7; CI: 1.1-2.5, increasing high: OR: 2.1; CI: 1.4-3.1), persons living in small cities/villages (moderately increasing: OR: 2.4; CI: 1.9-3.0, rapidly increasing: OR: 2.1; CI: 1.6-2.7, increasing high: OR: 2.6; CI: 2.0-3.3) and those with comorbid mental disorders, most pronounced regarding schizophrenia/psychoses (rapidly increasing: OR: 6.7; CI: 2.9-19.5, increasing high: OR: 12.8; CI: 5.5-37.0), autism spectrum disorders (rapidly increasing: OR: 4.6; CI: 3.1-7.1, increasing high: OR: 9.6; CI: 6.5-14.6), anxiety/stress-related disorders (moderately increasing: OR: 1.3; CI: 1.1-1.7, rapidly increasing: OR: 2.0; CI: 1.6-2.5, increasing high: OR: 1.8; CI: 1.5-2.3) and depression/bipolar disorder (moderately increasing: OR: 1.3; CI: 1.0-1.6, rapidly increasing: OR: 1.7; CI: 1.4-2.2, increasing high: OR: 1.5; CI: 1.2-1.9).Conclusions: About 61% of young adults were characterised by increasing LMM after a diagnosis of ADHD. To avoid marginalisation, attention should especially be given to young adults diagnosed with ADHD with a low educational level, that are single parents and who are living outside big cities. Also, young adults with comorbid mental disorders should be monitored for LMM early in working life.

- Aims.: To investigate whether adverse childhood experiences (ACEs) modify the impact of exposure to a natural disaster (the 2011 Great East Japan earthquake and tsunami) on the occurrence of posttraumatic stress disorder (PTSD) among older people. Methods.: Data were collected as part of the Japan Gerontological Evaluation Study (JAGES), which is an on-going epidemiological survey investigating social determinants of health among older people across Japan. Information on PTSD symptoms based on the Screening Questionnaire for Disaster Mental Health, traumatic exposure to the earthquake (i.e., house damage and loss of relatives/friends during the earthquake/tsunami) and ACEs was obtained from 580 participants aged 65 or older living in Iwanuma City, Miyagi Prefecture, which suffered severe damage as a result of the earthquake and the subsequent tsunami in March 2011. Associations were examined using Poisson regression analysis with a robust variance estimator after adjusting for covariates. Results.: The prevalence of PTSD was 9.7% in this population; compared to those with no traumatic experience, the prevalence of PTSD was approximately two times higher among those who experienced the loss of close friends/relatives (PR = 1.84, 95% CI = 1.11–3.03, p = 0.018), or whose house was damaged (PR = 2.15, 95% CI = 1.07–4.34, p = 0.032). ACE was not significantly associated with PTSD. Stratified analyses by the presence of ACE showed that damage due to the earthquake/tsunami was associated with PTSD only among those without ACEs; more specifically, among non-ACE respondents the PR of PTSD associated with house damage was 6.67 (95% CI = 1.66–26.80), while for the loss of a relative or a close friend it was 3.56 (95% CI = 1.18–10.75). In contrast, no statistically significant associations were observed among those with ACEs. Conclusion.: Following the Great East Japan earthquake/tsunami in 2011 a higher risk of developing PTSD symptoms was observed in 2013 especially among older individuals without ACEs. This suggests that ACEs might affect how individuals respond to subsequent traumatic events later in life.

- AIM: Research on the effect of oral contraceptive (OC) use on the risk of depression shows inconsistent findings, especially in adult OC users. One possible reason for this inconsistency is the omission of women who discontinue OCs due to adverse mood effects, leading to healthy user bias. To address this issue, we aim to estimate the risk of depression that is associated with the initiation of OCs as well as the effect of OC use on lifetime risk of depression.METHODS: This is a population-based cohort study based on data from 264,557 women from the UK Biobank. Incidence of depression was addressed via interviews, inpatient hospital or primary care data. The hazard ratio (HR) between OC use and incident depression was estimated by multivariable Cox regression with OC use as a time-varying exposure. To validate causality, we examined familial confounding in 7,354 sibling pairs.RESULTS: We observed that the first 2 years of OC use were associated with a higher rate of depression compared to never users (HR = 1.71, 95% confidence interval [CI]: 1.55-1.88). Although the risk was not as pronounced beyond the first 2 years, ever OC use was still associated with an increased lifetime risk of depression (HR = 1.05, 95% CI: 1.01-1.09). Previous OC use were associated with a higher rate of depression compared to never users, with adolescent OC users driving the increased hazard (HR = 1.18, 95% CI: 1.12-1.25). No significant association were observed among adult OC users who had previously used OCs (HR = 1.00, 95% CI: 0.95-1.04). Notably, the sibling analysis provided further evidence for a causal effect of OC use on the risk of depression.CONCLUSIONS: Our findings suggest that the use of OCs, particularly during the first 2 years, increases the risk of depression. Additionally, OC use during adolescence might increase the risk of depression later in life. Our results are consistent with a causal relationship between OC use and depression, as supported by the sibling analysis. This study highlights the importance of considering the healthy user bias as well as family-level confounding in studies of OC use and mental health outcomes. Physicians and patients should be aware of this potential risk when considering OCs, and individualized risk-benefit assessments should be conducted.

- Background. Parental psychopathology may increase the risk of attention-deficit hyperactivity disorder (ADHD) in the offspring. The aim of this study was to analyze if/how gender influences the association between parental psychiatric/addictive disorders and ADHD medication in the offspring.Methods. Register study in national birth cohorts of 1.1 million 6-19-year-olds. In this population, 7960 individuals with ADHD medication were identified in the Swedish Prescribed Drug Register during 2006. Data on parental psychiatric/addictive disorders and suicide death were obtained through linkages to national registers. Logistic regression was used for analyses with multiple adjustments for socio-economic, regional and demographic confounders.Results. Parental diagnosis related to illicit drugs was associated with the highest odds ratios (ORs) of ADHD medication (OR: similar to 3.5-4), followed by suicide attempt/death (OR: similar to 3-3.5), alcohol (OR: similar to 2.5-3), affective disorder (OR: similar to 2.5) and psychosis (OR: similar to 2-2.5). The ORs were of similar magnitudes for maternal and paternal psychopathology and did not vary by the gender of the offspring. Adjusting for social characteristics decreased the ORs substantially and in the same way regarding fathers' and mothers' possible influence on the risk of ADHD in children.Conclusions. Neither parental nor offspring gender seems to influence the link between parental addictive/psychiatric disorder and offspring ADHD.

- Aims. To investigate the patterns of use of different forms of psychiatric care in refugees who settled in Sweden as teenagers.Method. Cox proportional hazards models were used to estimate the use of different forms of psychiatric care from 2009 to 2012 in a population of 35 457 refugees, aged from 20 to 36, who had settled in Sweden as teenagers between 1989 and 2004. These findings were compared with 1.26 million peers from the same birth cohorts in the general Swedish population.Results. Unaccompanied and accompanied refugees were more likely to experience compulsory admission to a psychiatric hospital compared with the native Swedish population, with hazard ratios (HRs) of 2.76 (1.86–4.10) and 1.89 (1.53–2.34), respectively, as well as psychiatric inpatient care, with HRs of 1.62 (1.34–1.94) and 1.37 (1.25–1.50). Outpatient care visits by the young refugees were similar to the native Swedish population. The longer the refugees had residency in Sweden, the more they used outpatient psychiatric care. Refugees born in the Horn of Africa and Iran were most likely to undergo compulsory admission, with HRs of 3.98 (2.12–7.46) and 3.07 (1.52–6.19), respectively. They were also the groups who were most likely to receive inpatient care, with HRs of 1.55 (1.17–2.06) and 1.84 (1.37–2.47), respectively. Our results also indicated that the use of psychiatric care services increased with the level of education in the refugee population, while the opposite was true for the native Swedish population. In fact, the risks of compulsory admissions were particularly higher among refugees who had received a secondary education, compared with native Swedish residents, with HRs of 4.72 (3.06–7.29) for unaccompanied refugees and 2.04 (1.51–2.73) for accompanied refugees.Conclusions. Young refugees received more psychiatric inpatient care than the native Swedish population, with the highest rates seen in refugees who were not accompanied by their parents. The discrepancy between the use of inpatient and outpatient care by young refugees suggests that there are barriers to outpatient care, but we did note that living in Sweden longer increased the use of outpatient services. Further research is needed to clarify the role that education levels among Sweden's refugee populations have on their mental health and health-seeking behaviour.

- Aims. Adverse factors in the psychosocial work environment are associated with the onset of depression among those without a personal history of depression. However, the evidence is sparse regarding whether adverse work factors can also play a role in depression recurrence. This study aimed to prospectively examine whether factors in the psychosocial work environment are associated with first-time and recurrent treatment for depression.Methods. The study included 24,226 participants from the Danish Well-being in Hospital Employees study. We measured ten individual psychosocial work factors and three theoretical constructs (effort–reward imbalance, job strain and workplace social capital). We ascertained treatment for depression through registrations of hospital contacts for depression (International Statistical Classification of Diseases and Related Health Problems version 10 [ICD-10]: F32 and F33) and redeemed prescriptions of antidepressant medication (Anatomical Therapeutic Chemical [ATC]: N06A) in Danish national registries. We estimated the associations between work factors and treatment for depression for up to 2 years after baseline among those without (first-time treatment) and with (recurrent treatment) a personal history of treatment for depression before baseline. We excluded participants registered with treatment within 6 months before baseline. In supplementary analyses, we extended this washout period to up to 2 years. We applied logistic regression analyses with adjustment for confounding.Results. Among 21,156 (87%) participants without a history of treatment for depression, 350 (1.7%) had first-time treatment during follow-up. Among the 3070 (13%) participants with treatment history, 353 (11%) had recurrent treatment during follow-up. Those with a history of depression generally reported a more adverse work environment than those without such a history. Baseline exposure to bullying (odds ratio [OR] = 1.72, 95% confidence interval [95% CI]: 1.30–2.32), and to some extent also low influence on work schedule (OR = 1.27, 95% CI: 0.97–1.66) and job strain (OR = 1.24, 95% CI: 0.97–1.57), was associated with first-time treatment for depression during follow-up. Baseline exposure to bullying (OR = 1.40, 95% CI: 1.04–1.88), lack of collaboration (OR = 1.31, 95% CI: 1.03–1.67) and low job control (OR = 1.27, 95% CI: 1.00–1.62) were associated with recurrent treatment for depression during follow-up. However, most work factors were not associated with treatment for depression. Using a 2-year washout period resulted in similar or stronger associations.Conclusions. Depression constitutes a substantial morbidity burden in the working-age population. Specific adverse working conditions were associated with first-time and recurrent treatment for depression and improving these may contribute to reducing the onset and recurrence of depression.
