Duration of residence and psychotropic drug use in recently settled refugees in Sweden--a register-based study

Access to medicines among asylum seekers, refugees and undocumented migrants across the migratory cycle in Europe: a scoping review

INTRODUCTION

Access to essential medicines is a critical element of health systems and an important measure of their performance. Migrants may face barriers in accessing healthcare, including essential medicines, throughout the migration cycle, which includes the stages of departure from home or residence countries, transit through non-European or European countries, reception and settlement in a country in Europe and deportation. We aim to provide an overview of research and grey literature concerning access to essential medicines for asylum seekers, refugees and undocumented migrants in or heading to Europe (European Union, European Economic Area, Switzerland and the UK).

METHODS

To delineate and conceptualise access to medicines, we considered the definition of the Lancet Commission on Essential Medicines and the Pharmaceutical Management framework. These frameworks were combined to guide several critical steps in our review, including defining the search terms, data extraction, data analyses and reporting. Relevant studies and reports were identified through searches in bibliographic and grey literature databases.

RESULTS

Out of 5760 studies and 66 grey literature reports, 108 met the inclusion criteria, with 72 focusing on medicine access. Overall, medicine use and medicine expenditure were found to be lower in migrant populations compared with the host population in many European countries. Although many studies focused on the use of infectious disease and psychotropic medicines, the most frequently used medicines by migrants were analgesics, hypertension and diabetes medicines. Determinants of medicine access were legal restrictions, language and transit times, which all contributed to interruption of and inequities in access to medicines among this population. This scoping review also indicated significant gaps in the literature regarding the evidence on access to medicine at different stages of the migration cycle, specifically in departure, transit and deportation stages.

CONCLUSION

Overall, our findings highlighted significant unmet medicine needs among migrants in or on the way to Europe and access disparities attributable to various interconnected barriers. Urgent access is needed to address such inequities, particularly legal barriers, including registration of certain medicines required for treatment. Future research should prioritise investigating medicine access during departure, transit and deportation stages. Policy discussions around migrants' access to medicines should be centred on framing healthcare as a fundamental right.

Age of migration and common mental disorders among migrants in early adulthood: a Norwegian registry study

BACKGROUND

Younger age of migration is associated with higher risk of psychotic disorders but the relationship between age of migration and common mental disorders is less clear. This study investigates the association between age of migration and diagnosed common mental disorders among migrants living in Norway.

METHODS

Using national Norwegian register data from 2008 to 2019, we compared the odds of a common mental disorder diagnosis in healthcare services during early adulthood among non-migrants, descendants and migrants with different ages of migration and lengths of stay. We also investigated differences in the relationship for different migrant groups and for men and women.

RESULTS

Descendants and childhood migrants with ≥ 19 years in Norway had higher odds of common mental disorders than non-migrants, while those migrating during adolescence with ≥ 19 years in Norway had similar odds. Those migrating during emerging and early adulthood had lower odds. Overall among migrants, the relationship between age of migration and common mental disorders was more pronounced for migrants < 19 years in Norway than ≥ 19 years and for non-refugees compared with refugees, especially men.

CONCLUSIONS

Descendants and childhood migrants with long stays may have higher odds of common mental disorders due to the associated stress of growing up in a bicultural context compared with non-migrants. Age of migration has a negative association with diagnosed common mental disorders but much of this effect may attenuate over time. The effect appears weaker for refugees, and particularly refugee men, which may reflect higher levels of pre-migration trauma and stress associated with the asylum-seeking period for those arriving as adults. At the same time, migrants, especially those arriving as adults, experience barriers to care. This could also explain the particularly low odds of diagnosed common mental disorders among adult migrants, especially those with shorter stays.

Association of medication clusters and subsequent labor market marginalization in refugee and Swedish-born young adults with common mental disorders in Sweden

Little is known about the association between common mental disorders (CMD) and labor market integration among refugee and Swedish-born young adults. Socially disadvantaged patients such as refugees are more likely to discontinue their medication use prematurely. This study aimed to identify clusters of individuals with similar psychotropic medication patterns; and examine the relationship between cluster membership with labor market marginalization (LMM) in refugee and Swedish-born young adults with CMD. The study uses a longitudinal matched cohort aged 18-24 years with CMD diagnoses from Swedish registers covering 2006-2016. Dispensed psychotropic medications (antidepressants, antipsychotics, anxiolytics, sedative-hypnotics, mood stabilizers) were collected one year before and after CMD diagnosis. Clusters of patients with similar time courses of prescribed dosages were algorithmically identified. The association of cluster membership with subsequent LMM, (long-term sickness absence, SA, disability pension, DP, or long-term unemployment, UE) was assessed using Cox regression. Among 12,472 young adults with CMD, there were 13.9% with SA, 11.9% with DP, and 13.0% with UE during a mean follow-up of 4.1 years (SD 2.3 years). Six clusters of individuals were identified. A cluster with a sustained increase in all medication types yielded the highest hazard ratio (HR [95% CI]) 1.69 [1.34, 2.13] for SA and 2.63 [2.05, 3.38] for DP. The highest HRs of UE give a cluster with a concentrated peak in antidepressants at CMD diagnosis (HR 1.61[1.18, 2.18]). Refugees and Swedish-born showed similar associations between clusters and LMM. To prevent LMM, targeted support and early assessment of CMD treatment are needed for individuals with a sustained increase in psychotropic medication after CMD diagnosis and for refugees in high-risk clusters for UE characterized by a rapid lowering of treatment dosages, which could be an indicator for premature medication discontinuation.

Factors affecting adherence to psychotropics in trauma-affected refugees: data from a randomized controlled trial

Non-adherence to psychotropic drugs may reduce treatment effectiveness and may cause exacerbation of illness. Among migrant populations, studies have identified low adherence to psychotropic drugs. This study aimed to identify factors that were associated with the three basic components of adherence: non-initiation, non-implementation (blood sample), and discontinuation in a clinical sample of trauma-affected refugees diagnosed with posttraumatic stress disorder. The data for this study is derived from a randomized controlled trial (n = 108). Based on existing literature, individual sociodemographic and clinical candidate predictor variables that may affect the initiation, continuation, and implementation to psychotropics were selected as exposure variables. Logistic regression was used to assess the risk relation between non-initiation, non-implementation, discontinuation, and the individual sociodemographic and clinical factors. Three factors - level of education, turn-up rate for medical doctor sessions, and discomfort in relation to the psychotropics - were associated with non-initiation, non-implementation, or discontinuation. The relatively small sample size poses a limitation. Furthermore, factors not examined in the current study may have affected non-initiation, non-implementation, and discontinuation. The study identified level of education, turn-up rate for medical doctor sessions, and discomfort in relation to medicine as important factors in relation to treatment with psychotropics in trauma-affected refugees. Factors contributing to a low turn-up rate, and factors that are consequences of a low turn-up rate, as well as communication and trust in the patient-provider interaction need further research attention. Furthermore, there is a need for research on interventions addressing adherence for refugees with mental illness.

Use of benzodiazepine and related drugs in migrants and Finnish-born persons: a nationwide register-based study

AIMS

Benzodiazepines and related drugs (BZDR) are often used longer than generally recommended. The aim is to study patterns of use among migrant and Finnish-born users of BZDR, and to identify factors that are associated with long-term use and BZDR polytherapy.

METHODS

This register-based study includes a nationwide sample of migrants (n=8729) and their Finnish-born controls (n=11 388) who had purchased BZDR in 2011-2014, but not in 2009-2010. Information on drug purchases was obtained from the National Prescription Register and the duration of drug use was estimated using PRE2DUP method. The main outcomes were long-term use of BZDR, polytherapy and time until discontinuation of BZDR use. Sociodemographic variables and information on preceding psychiatric diagnoses were included as covariates. Logistic and Cox regression analyses were the statistical methods used.

RESULTS

Only migrants from Sub-Saharan Africa were more likely to discontinue the medication once initiated than Finnish-born users. Migrants were significantly less likely to be long-term users (adjusted odds ratio 0.79, 95% CI 0.70-0.89) or polytherapy users (aOR 0.90, 95% CI 0.84-0.97) of BZDR compared with Finnish-born participants.

CONCLUSIONS

Migrants had less long-term and concomitant use of several BZDR than Finnish-born participants. The pattern of use is more optimal among migrants, but it may also reflect poorer access to mental health treatment.

Processes of Care and Associated Factors in Patients With Stroke by Immigration Status

BACKGROUND

Receiving evidence-based stroke care processes is associated with good clinical outcome. However, data on early stroke care among immigrants are scarce.

OBJECTIVE

We investigated whether guideline-recommended acute stroke care and associated factors differ between immigrants and Danish-born residents.

DESIGN

Patients admitted with ischemic and hemorrhagic stroke diagnoses (n=129,724) between 2005 and 2018 were identified from the Danish Stroke Registry.

RESULTS

We included 123,928 Danish-born residents and 5796 immigrants with stroke. Compared with Danish-born residents, immigrants were less likely to be admitted to a stroke unit within 24 hours after stroke onset (81.5% vs. 83.9%, P <0.001) and had lower odds of early stroke care including dysphagia screening, physiotherapy, occupational therapy, and nutritional assessment. After adjustment for age, sex, clinical, and sociodemographic factors, immigrants had lower odds of early stroke unit admission (odds ratio [OR]: 0.97; 95% CI, 0.94-0.99), early dysphagia screening (OR: 0.96; 95% CI, 0.93-0.98), early physiotherapy (OR: 0.96; 95% CI, 0.94-0.99), and early occupational therapy (OR: 0.96; 95% CI, 0.93-0.98) than Danish-born residents. Small absolute differences in overall quality of stroke care were found when comparing immigrants and Danish-born residents. Significant factors associated with greater likelihood of stroke care included high income, high education, and cohabitation.

CONCLUSIONS

Immigrants had lower chances of early stroke unit admission and received fewer individual early stroke care processes such as dysphagia screening, physiotherapy and occupational therapy than Danish-born residents. However, the absolute disparities were in general minor and largely influenced by socioeconomic status and cohabitation.

Mental health by native–immigrant intermarriage in Sweden: a register-based retrospective cohort study

Background

Native–immigrant intermarriage is often regarded as a proxy for integration, given that intermarried immigrants are more socioeconomically and culturally similar to natives than intramarried immigrants. This study aimed to assess whether integration affects mental health and care-seeking behaviours, examining prescription hazards for psychotropic medications by native–immigrant marital composition in Sweden.

Methods

Total population register data were used to identify first-time married couples residing in Sweden between 31 December 2005 and 31 December 2016. Index persons were distinguished by gender and partners’ origin (native vs. immigrant), as well as by immigrants’ regions of origin, with intramarried natives as references. Using Cox regression, hazard ratios (HRs) with 95% confidence intervals (95% CIs) were calculated for antidepressant and anxiolytic prescriptions and adjusted for socioeconomic factors, presence of children and length and quality of marriage.

Results

Intramarried immigrant women had higher psychotropic prescription hazards than intramarried native references (HR 1.11, 95% CI 1.10–1.12), whereas intermarried immigrant women had equal hazards. Immigrant women’s hazards were lower than native references after adjustment. Intramarried immigrant men had the greatest prescription hazards (HR 1.33, 95% CI 1.32–1.34), and intermarried immigrant men slightly higher hazards (HR 1.11, 95% CI 1.10–1.13), than intramarried natives. All were partly attenuated after adjustment. Intermarriage hazards increased by similarities in regions of origin, especially among men.

Conclusions

Integration indicated by intermarriage appears to be protective for the mental health of immigrants, especially for immigrant men. Future research should empirically disentangle the social, cultural and socioeconomic mechanisms underlying these health differences.

Differences in psychiatric care utilization between refugees, non-refugee migrants and Swedish-born youth

BACKGROUND

The study aimed to examine differences in, and characteristics of psychiatric care utilization in young refugees who came to Sweden as unaccompanied or accompanied minors, compared with that of their non-refugee immigrant and Swedish-born peers.

METHODS

This register-linkage cohort study included 746 688 individuals between 19 and 25 years of age in 2009, whereof 32 481 were refugees (2896 unaccompanied and 29 585 accompanied) and 32 151 non-refugee immigrants. Crude and multivariate Cox regression models yielding hazard ratios (HR) and 95% confidence intervals (CI) were conducted to investigate subsequent psychiatric care utilization for specific disorders, duration of residence and age at migration.

RESULTS

The adjusted HRs for psychiatric care utilization due to any mental disorder was significantly lower in both non-refugee and refugee immigrants when compared to Swedish-born [aHR: 0.78 (95% CI 0.76-0.81) and 0.75 (95% CI 0.72-0.77, respectively)]. Within the refugee group, unaccompanied had slightly lower adjusted risk estimates than accompanied. This pattern was similar for all specific mental disorders except for higher rates in schizophrenia, reaction to severe stress/adjustment disorders and post-traumatic stress disorder. Psychiatric health care utilization was also higher in immigrants with more than 10 years of residency in Sweden entering the country being younger than 6 years of age.

CONCLUSIONS

For most mental disorders, psychiatric health care utilization in young refugees and non-refugee immigrants was lower than in their Swedish-born peers; exceptions are schizophrenia and stress-related disorders. Arrival in Sweden before the age of 6 years was associated with higher rates of overall psychiatric care utilization.

Treatment adherence to psychotropic drugs among non-Western migrants: a systematic review

BACKGROUND

Low medication adherence is a significant challenge in all medical fields and particularly in mental health treatment, where a lack of insight into one's own disease can repress the ability to adhere. In recent years, the increase in migration combined with a high prevalence of mental illnesses among migrants and the possible consequences of nonadherence, point towards the need for a focus on adherence with psychotropic drugs among migrants.

AIM

To review current literature, exploring the potential impact of being a migrant from a non-Western country living in a Western country on the level of adherence to psychotropic medication and subsequently to discuss these findings.

METHODS

A systematic review of studies investigating adherence among non-western migrants was conducted. The literature search was conducted using PubMed and Embase databases in October 2020.

RESULTS

Seven observational studies were included, all ranging from moderate to high-quality. Six out of seven studies found an association between being a non-Western migrant in a Western country and low adherence to psychotropic drugs.

CONCLUSION

Studies indicate an association between being a non-Western migrant in a Western country and low adherence to psychotropic drugs. None of the included studies investigated possible causes of the low adherence in migrants. Communication difficulties are, however, considered possible barriers to healthcare access and a contributing factor to nonadherence. There is a need for studies assessing the possible impact of interventions aiming at increasing adherence such as intercultural mediators and training of healthcare providers in cultural competencies.

Are all children treated equally? Psychiatric care and treatment receipt among migrant, descendant and majority Swedish children: a register-based study

AIMS

Underutilisation of mental health services among migrant youth has been demonstrated repeatedly, but little is known about potential discrepancies in terms of treatment receipt for those who do reach services. This study examines the type and level of care received among migrant children and descendants of migrants, particularly investigating disparities in treatment receipt given a specific diagnosis.

METHODS

We used register data of the total population aged 6-17 years in Stockholm, followed from 2006 to 2015, comprising 444 196 individuals, categorised as refugees, non-refugee migrants, descendants of migrants and Swedish-born. To identify recommended treatments for specific diagnoses we used official clinical guidelines. We report logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs) of diagnosis receipt, treatment provision and level of care where a diagnosis was first registered.

RESULTS

Migrant children had a lower likelihood of receiving a wide range of psychiatric diagnoses, including mood disorder (OR 0.58; 95% CI 0.52-0.64), anxiety disorder (OR 0.62; 95% CI 0.57-69) and neurodevelopmental disorder (OR 0.59; 95% CI 0.55-0.63). Moreover, when these diagnoses were set, migrant children had a lower likelihood of receiving the recommended treatments for these conditions compared to the majority individuals with the same diagnosis (OR of receiving psychotherapy for anxiety disorder and depression: 0.71; 95% CI 0.62-0.95 and 0.50; 95% CI 0.33-0.75, respectively; OR for receiving ADHD-medication: 0.49; 95% CI 0.43-0.54).

CONCLUSIONS

Migrant children risk underdiagnosis of various mental health conditions, and, when reaching mental health services, risk not receiving the optimal care available.

Antidepressant use among immigrants with depressive disorder living in Finland: A register-based study

BACKGROUND

The aim of this study was to examine differences in the initiation and discontinuation of antidepressants between immigrants and the Finnish-born population diagnosed with depression in specialized health care.

METHODS

The study utilized register-based data, which includes all immigrants living in Finland at the end of 2010 and matched Finnish-born controls. For this study, we selected individuals who had received a diagnosis of depression during 2011-2014 (immigrants n = 2244, Finnish-born n = 2773). Their antidepressant use was studied for a one-year period from initiation. A logistic regression was used to predict initiation and a Cox regression was used to predict discontinuation.

RESULTS

Immigrants were more likely to initiate the use of antidepressants than the Finnish-born controls (adjusted OR = 1.25, 95% CI = 1.07-1.46), but they also discontinued the medication earlier than the Finnish-born controls (adjusted HR = 1.48, 95% CI = 1.31-1.68). Immigrants from Sub Saharan Africa, the Middle East and Northern Africa were most likely to discontinue antidepressants earlier. More severe depression, a longer length of residence in Finland and more intensive psychiatric treatment were associated with decreased risk of discontinuation.

LIMITATIONS

The registers do not provide information on the perceived reasons for the discontinuation.

CONCLUSIONS

Immigrants with depression initiate antidepressants more often than the Finnish-born population, but they also discontinue them earlier. Early discontinuation may be a sign of insufficient treatment suggesting that there could be a need for improvement in mental health care for immigrants in Finland.

Trajectories of antidepressant use and characteristics associated with trajectory groups among young refugees and their Swedish-born peers with diagnosed common mental disorders-findings from the REMAIN study

PURPOSE

This study aimed to (1) identify the trajectories of prescribed antidepressants in refugee youth and matched Swedish-born peers diagnosed with common mental disorder (CMD) and (2) characterize the trajectories according to sociodemographic and medical factors.

METHODS

The study population comprised 2,198 refugees and 12,199 Swedish-born individuals with both Swedish-born parents, aged 16-25 years in 2011, residing in Sweden and treated in specialised healthcare for CMD 2009-11. Group-based trajectory modelling was used to identify different trajectory groups of antidepressant use-based on annual defined daily dosages (DDDs). Multinomial logistic regression was applied to investigate the association of sociodemographic and medical characteristics with the identified trajectories. Nagelkerke pseudo-R² values were estimated to evaluate the strength of these associations.

RESULTS

Four trajectory groups of antidepressant use among young refugees were identified with following proportions and DDD levels in 2011: 'low constant' (88%, < 100), 'low increasing' (2%, ≈710), 'medium decreasing' (8%, ≈170) and 'high increasing' (2%, ≈860). Similar trajectories, however, with different proportions were identified in Swedish-born: 67%, 7%, 21% and 5%, respectively. The most influential factors discriminating the trajectory groups among refugees were 'duration of stay in Sweden' (R² = 0.013), comorbid 'other mental disorders' (R² = 0.009) and 'disability pension' (R² = 0.007), while 'disability pension' (R² = 0.017), comorbid 'other mental disorders' (R² = 0.008) and 'educational level' (R² = 0.008) were the most important determinants discriminating trajectory groups among Swedish-born youth.

CONCLUSION

The lower use of antidepressants in refugees with CMDs compared to their Swedish-born counterparts warrants health literacy programs for refugees and training in transcultural psychiatry for healthcare professionals.

Persistence of antidepressant use among refugee youth with common mental disorder

BACKGROUND

The objective of this study was to investigate whether persistence of antidepressant use differs between refugee youth and Swedish-born youth after a diagnosis of a common mental disorder (CMD), and if clinical and sociodemographic factors are associated with antidepressant discontinuation.

METHODS

Youth aged 16-25 years, with an incident diagnosis of CMD (depression, post-traumatic stress disorder (PTSD), anxiety disorders) accessing specialized healthcare in Sweden 2006-2016 were included. New users were identified with a one-year washout period. Refugees (N=1575) were compared with Swedish-born youth (N=2319). Cox regression models [reported as adjusted Hazard Ratios (HRs) with 95% confidence intervals (CIs)] were used to investigate factors associated with discontinuation of antidepressant use.

RESULTS

Among youth (mean age 20.9 years, SD 2.7, 50% females), the median duration of antidepressant use differed considerably between refugee (101 days, IQR 31-243) and Swedish-born youth (252 days, IQR 101-558). Refugees were more likely to discontinue treatment (HR 1.61, 95% CI 1.47-1.77). Factors associated with an increased risk for discontinuation in refugees included ≤5 years duration of formal residency (HR 1.28, 95% CI 1.12-1.45), antidepressant type, and dispensing lag (time from prescription to dispensing) of >7 days (1.43, 1.25-1.64), whereas PTSD (0.78, 0.64-0.97) and anxiolytic use (0.79, 0.64-0.96) were associated with a lower discontinuation risk.

LIMITATIONS

Only persons treated in specialized healthcare could be included.

CONCLUSION

The relatively short treatment durations among refugee youth suggest that antidepressant treatment may not be optimal in CMD, and better monitoring of treatment as well as transcultural education of healthcare personnel are warranted.

Perceived barriers to care for migrant children and young people with mental health problems and/or neurodevelopmental differences in high-income countries: a meta-ethnography

OBJECTIVES

To develop conceptual understanding of perceived barriers to seeking care for migrant children and young people (aged 0-25 years) with mental health problems and/or neurodevelopmental differences in high-income countries.

DESIGN

Qualitative evidence synthesis using meta-ethnography methodology. We searched four electronic databases (Medline, PsycINFO, Global Health and Web of Science) from inception to July 2019 for qualitative studies exploring barriers to care (as perceived by migrant communities and service providers) for migrant children and young people in high-income countries with neurodevelopmental differences and/or mental health problems. The quality of included studies was explored systematically using a quality assessment tool.

RESULTS

We screened 753 unique citations and 101 full texts, and 30 studies met our inclusion criteria. We developed 16 themes representing perceived barriers to care on the supply and demand side of the care-seeking process. Barriers included: stigma; fear and mistrust of services; lack of information on mental health and service providers lacking cultural responsiveness. Themes were incorporated into Levesque et al's conceptual framework of patient-centred access to healthcare, creating a version of the framework specific to migrant children and young people's mental health and neurodevelopmental differences.

CONCLUSIONS

This is the first qualitative evidence synthesis on barriers to care for mental health problems and/or neurodevelopmental differences in migrant children and young people in high-income countries. We present an adapted conceptual framework that will help professionals and policy-makers to visualise the complex nature of barriers to care, and assist in improving practice and designing interventions to overcome them. Similar barriers were identified across study participants and migrant populations. While many barriers were also similar to those for children and young people in general populations, migrant families faced further, specific barriers to care. Interventions targeting multiple barriers may be required to ensure migrant families reach care.

Trajectories of antidepressant use before and after a suicide attempt among refugees and Swedish-born individuals: a cohort study

Background

To identify key information regarding potential treatment differences in refugees and the host population, we aimed to investigate patterns (trajectories) of antidepressant use during 3 years before and after a suicide attempt in refugees, compared with Swedish-born. Association of the identified trajectory groups with individual characteristics were also investigated.

Methods

All 20–64-years-old refugees and Swedish-born individuals having specialised healthcare for suicide attempt during 2009–2015 (n = 62,442, 5.6% refugees) were followed 3 years before and after the index attempt. Trajectories of annual defined daily doses (DDDs) of antidepressants were analysed using group-based trajectory models. Associations between the identified trajectory groups and different covariates were estimated by chi²-tests and multinomial logistic regression.

Results

Among the four identified trajectory groups, antidepressant use was constantly low (≤15 DDDs) for 64.9% of refugees. A ‘low increasing’ group comprised 5.9% of refugees (60–260 annual DDDs before and 510–685 DDDs after index attempt). Two other trajectory groups had constant use at medium (110–190 DDDs) and high (630–765 DDDs) levels (22.5 and 6.6% of refugees, respectively). Method of suicide attempt and any use of psychotropic drugs during the year before index attempt discriminated between refugees’ trajectory groups. The patterns and composition of the trajectory groups and their association, discriminated with different covariates, were fairly similar among refugees and Swedish-born, with the exception of previous hypnotic and sedative drug use being more important in refugees.

Conclusions

Despite previous reports on refugees being undertreated regarding psychiatric healthcare, no major differences in antidepressant treatment between refugees and Swedish-born suicide attempters were found.

Initiation of antidepressant use among refugee and Swedish-born youth after diagnosis of a common mental disorder: findings from the REMAIN study

PURPOSE

The objective of this study was to compare the initiation and type of antidepressant use between refugees and matched Swedish-born youth after a diagnosis of a common mental disorder (CMD) and assess sociodemographic and clinical factors associated with the initiation.

METHODS

The study cohort included youth aged 16-25 years, with an incident diagnosis of CMD based on specialized health care registers in Sweden 2006-2016, without prior antidepressant use during 1 year. One Swedish-born person was matched for each identified refugee youth (N = 3936 in both groups). Initiation of antidepressant use and factors associated with the initiation, were investigated with logistic regression yielding Odds ratios, OR, and 95% Confidence Intervals, CI.

RESULTS

Refugees were less likely to initiate antidepressant use compared with Swedish-born (40.5% vs. 59.6%, adjusted OR 0.43, 95% CI 0.39-0.48). Selective serotonin reuptake inhibitors (SSRIs) were less frequently initiated for refugees than Swedish-born (71.2% vs. 81.3% of initiations, p < 0.0001). Sertraline was the most commonly initiated antidepressant both for refugees (34.3%) and Swedish-born individuals (40.3%). Among refugees, factors associated with increased odds of antidepressant initiation were previous use of anxiolytics or hypnotics, previous sickness absence of < 90 days, cancer and older age (OR range 1.07-2.72), and less than 5 years duration of residency in Sweden was associated with decreased odds (OR 0.76, 95% CI 0.63-0.92).

CONCLUSION

Young refugees with a CMD seem to initiate antidepressants in general and those most effective considerably less often than their Swedish-born counterparts.

Risk of labour market marginalisation among young refugees and non-refugee migrants with common mental disorders

PURPOSE

Labour market marginalisation (LMM), i.e. long-term unemployment (LTU), long-term sickness absence (LTSA) and disability pension (DP), among young individuals with common mental disorders (CMDs) are a challenge for the welfare system, and refugees and non-refugee migrants seem particularly vulnerable. The aim was to investigate the risk of LMM in young adults with CMDs among refugees and non-refugee migrants compared to Swedish-born individuals and the role of country of birth, duration of residence and age at arrival.

METHODS

A prospective cohort study was conducted including young adults (19-30 years) with inpatient or specialised outpatient healthcare due to CMDs and/or antidepressant prescriptions during 2009 (N = 69,515). Cox regression models were used to calculate hazard ratios (HRs) with 95% confidence intervals for the risk of LMM during 2010-2013.

RESULTS

Both refugees and non-refugee migrants had a higher risk of LTU compared to Swedish-born individuals (HR refugees: Africa: 2.4; Asia: 2.2; Europe outside EU25: 1.6; South America: 1.4) with highest estimates in refugees from Afghanistan and Syria. Refugees from Africa and Asia had a lower risk of LTSA compared to Swedish-born individuals (HR: 0.6 and 0.7, respectively), particularly refugees from Afghanistan and Iraq. Especially among refugees, a longer duration of residence and a younger age at arrival were associated with a lower risk of LTU.

CONCLUSIONS

The risk of LTU among refugees and non-refugee migrants was higher and the risk of LTSA was lower, compared to Swedish-born individuals. Duration of residence and age at arrival had an influence on the risk of LTU, particularly among refugees.

The Pattern of Medication Use Amongst a Migrant Population Residing in Southern Iran: A Population-Based Study

Background: Iran has welcomed a large population of immigrants and refugees, which has led to new demands and priorities in many aspects of life, such as healthcare services. Objectives: For the first time in Southern Iran, in Shiraz City, population-based research was conducted on the patterns of medication use in native non-Iranian residents. Methods: The present cross-sectional study was conducted amongst Shiraz citizens from 2017 to 2018. The population consisted of 43 migrants. Data were collected using a multipart data form. All statistical analyses were performed using SPSS. Results: A total of 43 Afghan migrants were included in the study. Most of them were female (72.1%), aged under 40 years (67.4%), and homemaker (62.8%) with an education level of non-completed high school diploma (97.7%). The majority of the subjects did not have insurance or family physician coverage (93%), and 85.7% got medications without prescription. The three most common medications used by the subjects were iron supplements, acetaminophen, and cold medicines. Conclusions: Iran is now hosting Afghan nationals as one of the largest population of refugees in the world. The health conditions of the Afghan population need more attention in order to improve the health status of their community in Iran.

Barriers to Accessing and Negotiating Mental Health Services in Asylum Seeking and Refugee Populations: The Application of the Candidacy Framework

This review brought together research investigating barriers asylum seekers and refugees (AS&R) face in accessing and negotiating mental health (MH) services. The candidacy framework (CF) was used as synthesizing argument to conceptualize barriers to services (Dixon-Woods et al. in BMC Med Res Methodol 6:35, 2006). Five databases were systematically searched. Twenty-three studies were included and analyzed using the CF. The seven stages of the framework were differentiated into two broader processes-access and negotiation of services. Comparatively more data was available on barriers to access than negotiation of services. The Identification of Candidacy (access) and Appearances at Services (negotiation) were the most widely discussed stages in terms of barriers to MH care. The stage that was least discussed was Adjudications (negotiation). The CF is useful to understand inter-related barriers to MH care experienced by AS&R. A holistic approach is needed to overcome these barriers together with further research investigating understudied areas of candidacy.

Purchases of psychotropic drugs among the migrant population in Finland: a nationwide register-based cohort study

Background

Migrant populations may have different mental health service needs when compared with native populations. One indicator of service use is the use of psychotropic medication. The aim of this study was to compare the purchases of psychotropic drugs among different migrant populations with the native population in Finland.

Methods

Foreign-born participants (n = 184 805) and their Finnish-born controls (n = 185 183) were identified from the Finnish Central Population Register. Information on their purchases of psychotropic drugs in 2011–15 was collected from the National Prescription Register. A washout period of 2009–10 was used to define incident purchases. Cox regression analysis was the statistical method used.

Results

At least one incident purchase of a psychotropic drug was identified for 11.1% of migrant women, 11.4% of Finnish-born women, 8.7% of migrant men and 9.8% of Finnish-born men. When controlled for age, sex, marital status, socioeconomic status and social assistance, migrants were less likely to purchase psychotropic drugs (adjusted hazard ratio 0.96, 95% confidence interval 0.93–0.98), but there was variation between different drug categories. Recent migrants and migrants from Asia and Sub-Saharan Africa were least likely to purchase drugs. Migrants from Nordic countries and other Western countries most closely resembled the Finnish-born controls.

Conclusions

Recent migrants in Finland appear to use fewer psychotropic drugs than native Finns. It is important to analyze the reasons for this pattern, as they may indicate delays in access to care or benefits. The heterogeneity of migrant populations must also be considered when developing services to better address their needs.

Implementation of Advanced Methods for Reproductive Pharmacovigilance in Autism: A Meta-Analysis of the Effects of Prenatal Antidepressant Exposure

OBJECTIVE

Observational studies of prenatal antidepressant safety are hindered by methodological concerns, including susceptibility to surveillance bias. Some studies address potential bias by using alternative strategies to operationalize study comparison groups. In a meta-analysis of the association between prenatal antidepressant exposure and autism risk, the authors examined the utility of comparison group operationalization in reducing surveillance bias.

METHODS

A systematic search of multiple databases through August 2017 was conducted, selecting controlled observational studies of the association of prenatal antidepressant exposure with autism. Study quality was assessed using the Newcastle-Ottawa Scale. Random-effects meta-analysis produced summary effect measures with 95% confidence intervals stratified by comparator group composition, antidepressant class, and trimester of exposure.

RESULTS

Fourteen studies were included, with 13 reporting results using a population-based comparison group, five using a psychiatric control group, and four using a discordant-sibling control group. Eight of the 14 studies were rated poor because of inadequate control for prenatal depression and maternal ethnicity. Autism risk estimates after prenatal exposure to any antidepressant were decidedly different for population-based designs (hazard ratio=1.42, 95% CI=1.18, 1.70; odds ratio=1.58, 95% CI=1.25, 1.99) compared with psychiatric control (hazard ratio=1.14, 95% CI=0.84, 1.53; odds ratio=1.24, 95% CI=0.93, 1.66) and discordant-sibling (hazard ratio=0.97, 95% CI=0.68, 1.37; odds ratio=0.85, 95% CI=0.54, 1.35) designs. Findings for prenatal exposure to selective serotonin reuptake inhibitors were similar. Meta-regression of population-based studies demonstrated that despite statistical adjustment, ethnicity differences remained a significant source of study heterogeneity.

CONCLUSIONS

In this meta-analysis, neither psychiatric control nor discordant-sibling designs supported an association between prenatal antidepressant exposure and autism. Discordant-sibling designs effectively addressed surveillance bias in pharmacovigilance reports derived from national registries and other large databases.

Common mental disorders among young refugees in Sweden: The role of education and duration of residency

BACKGROUND

Studies investigating risks of common mental disorders (CMDs) in refugee youth are sparse. The current study examined health care use due to CMDs in unaccompanied and accompanied refugee youth and Swedish-born, and the role of education and residency duration.

METHODS

This longitudinal cohort study included 746,517 individuals (whereof 36,347 refugees) between 19 and 25 years, residing in Sweden in 2009. Refugees were classified as unaccompanied/accompanied. Risk estimates of CMDs, measured as health care use and antidepressant treatment, between 2010-2016 were calculated as adjusted hazard ratios (aHR) with 95% confidence intervals (CI). Highest attained education in 2009, and residency duration were examined as potential modifiers.

RESULTS

Compared to Swedish-born youth, refugees had a lower risk of treated major depressive and anxiety disorders (aHR): 0.67 (95% CI 0.63-0.72) and 0.67 (95% CI 0.63-0.71) respectively), but a higher risk for posttraumatic stress disorders (PTSD). Compared to Swedish-born, unaccompanied had a nearly 6-fold elevated risk for PTSD (aHR: 5.82, 95% CI 4.60-7.34) and accompanied refugees had a 3-fold risk of PTSD (aHR: 3.08, 95% CI 2.54-3.74). Rates of PTSD decreased with years spent in Sweden. The risk of CMDs decreased with increasing education.

LIMITATIONS

The study lacked information on pre-migration factors. There may further be a potential misclassification of untreated CMDs.

CONCLUSION

Refugees had a lower risk of treated depressive and anxiety disorders but a higher risk for PTSD. In refugees, the rates of anxiety disorders increased slightly over time whereas the rates of PTSD decreased. Last, low education was an important predictor for CMDs.

Structural and socio-cultural barriers to accessing mental healthcare among Syrian refugees and asylum seekers in Switzerland

Background: Due to their experiences of major stressful life events, including post-displacement stressors, refugees and asylum seekers are vulnerable to developing mental health problems. Yet, despite the availability of specialized mental health services in Western European host countries, refugees and asylum seekers display low mental healthcare utilization. Objective: The aim of this study was to explore structural and socio-cultural barriers to accessing mental healthcare among Syrian refugees and asylum seekers in Switzerland. Method: In this qualitative study, key-informant (KI) interviews with Syrian refugees and asylum seekers, Swiss healthcare providers and other stakeholders (e.g. refugee coordinators or leaders) were conducted in the German-speaking part of Switzerland. Participants were recruited using snowball sampling. Interviews were audiotaped and transcribed, and then analysed using thematic analysis, combining deductive and inductive coding. Results: Findings show that Syrian refugees and asylum seekers face multiple structural and socio-cultural barriers, with socio-cultural barriers being perceived as more pronounced. Syrian key informants, healthcare providers, and other stakeholders identified language, gatekeeper-associated problems, lack of resources, lack of awareness, fear of stigma and a mismatch between the local health system and perceived needs of Syrian refugees and asylum seekers as key barriers to accessing care. Conclusions: The results show that for Syrian refugees and asylum seekers in Switzerland several barriers exist. This is in line with previous findings. A possible solution for the current situation might be to increase the agility of the service system in general and to improve the willingness to embrace innovative paths, rather than adapting mental healthcare services regarding single barriers and needs of a new target population.

Differences in psychiatric care utilisation among unaccompanied refugee minors, accompanied migrant minors, and Swedish-born minors

PURPOSE

To better understand underutilisation of psychiatric care among migrant children, we compared utilisation of psychiatric care among unaccompanied refugee minors and accompanied migrant minors, with Swedish-born minors.

METHODS

Using a large longitudinal database of linked national registers, we established a retrospective cohort of 1,328,397 people born 1984-1988 comparing minors born in Sweden to 2 Swedish-born parents (95.4%) to minors who had been arriving in Sweden between 2002 and 2011 with a permanent resident permit and were either unaccompanied refugee minors (0.4%), or accompanied migrant minors (4.0%). The outcome measures were different measures of psychiatric care including in- and outpatient care, and prescribed psychotropic medication.

RESULT

Compared with the Swedish-born minors the unaccompanied refugee minors had a higher likelihood of utilisation of all psychiatric care except ADHD medication. However, compared with accompanied migrant minors, the Swedish-born minors had a higher likelihood of having utilised psychiatric care.

CONCLUSION

Our study shows that during the first years of living in Sweden, there seems to be fewer barriers to psychiatric care for unaccompanied refugee minors compared to the accompanied migrant minors. There are a number of possible reasons for this including stronger ties with the Swedish society.

First-generation migrants' use of psychotropic medication in Northern Ireland: a record linkage study

PURPOSE

There is a recent and growing migrant population in Northern Ireland. However, rigorous research is absent regarding access to mental health care by different migrant groups. In order to address this knowledge gap, this study aimed to identify the relative use of psychotropic medication between the largest first generation migrant groups in Northern Ireland and the majority population.

METHODS

Census (2011) data was linked to psychotropic prescriptions for the entire enumerated population of Northern Ireland using data linkage methodology through the Administrative Data Research Centre Northern Ireland (ADRC-NI).

RESULTS

Lower prescription dispensation for all psychotropic medication types, particularly antidepressants (OR = 0.35, CI 95% 0.33-0.36) and anxiolytics (OR = 0.42, CI 95% 0.40-0.44), was observed for all migrant groups with the exception of migrants from Germany.

CONCLUSIONS

It is likely that the results reflect poorer access to services and indicate a need to improve access and the match between resources, services and the health and social care needs of migrants. Further research is required to identify barriers to accessing primary care and mental health services.

Antidepressant medication use among working age first-generation migrants resident in Finland: an administrative data linkage study

BACKGROUND

A higher risk of common mental health disorders has been found for first-generation migrants in high income countries, but few studies have examined the use of mental health care. This study aimed to identify the level of antidepressant use amongst the largest first generation migrant groups resident in Finland.

METHODS

This cohort study used record-based data linkage methodology to examine the hazard of antidepressant use between migrant groups in Finland using Cox proportional hazard models. Data was derived using socio-demographic and prescription data from Statistics Finland and the Finnish Population Registry. The cohort included a random sample of 33% of the working age population in 2007 (N = 1,059,426, 49.8% women, 2.5% migrants) and dispensed antidepressant prescriptions from 2008 to 2014.

RESULTS

After adjustment for socio-demographic characteristics, results show higher antidepressant use for female migrants from North Africa and the Middle East compared to the Finland-born majority, a similar level of use for migrants from Western countries, and lower use for migrants from other non-Western countries.

CONCLUSIONS

The gender and country of origin dependent use of antidepressant medication is discussed in terms of socio-political and cultural between-group differences. Recommendations are made to address inequalities in accessing services, particularly for migrants from non-Western countries.

Severe maternal morbidity and postpartum mental health-related outcomes in Sweden: a population-based matched-cohort study

We examined whether women experiencing severe maternal morbidity (SMM) are more likely to be treated for a psychiatric illness or be prescribed psychotropic medications in the postpartum year than mothers who did not experience SMM. We also examine the relationship between SMM and specific mental health-related outcomes, and the relationship between specific SMM diagnoses/procedures and postpartum mental-health-related outcomes. The national registers in Sweden were used to create a population-based matched cohort. Every delivery with SMM between July 1, 2006, and December 31, 2012 (n = 8558), was matched with two deliveries without SMM (n = 17,116). Conditional logistic regression models assessed the relationship between SMM and postpartum mental health-related outcomes. Women who experienced SMM had significantly greater odds of being treated for a psychiatric disorder (aOR 1.22; 95% CI 1.03-1.45) and being prescribed psychotropic medications (aOR 1.40; 95% CI 1.24-1.58) in the postpartum year. Specifically, they had significantly greater odds of being treated for neuroses (aOR 1.35; 95% CI 1.09-1.69) and having a prescription for anxiolytics/hypnotics (aOR 1.36; 95% CI 1.18-1.58) or antidepressants (aOR 1.35; 95% CI 1.17-1.55). Women who were diagnosed with shock or uterine rupture/obstetric laparotomy during delivery had the greatest odds of postpartum mental health-related outcomes. This study identified mothers with SMM as a group at high risk for postpartum mental illness. Postpartum mental health services should be provided to ensure the well-being of these high-risk mothers.

Mental health care utilisation and access among refugees and asylum seekers in Europe: A systematic review

BACKGROUND

Refugees and asylum seekers often have increased mental health needs, yet may face barriers in accessing mental health and psychosocial support (MHPSS) services in destination countries. The aim of this systematic review is to examine evidence on MHPSS service utilisation and access among refugees and asylum seekers in European Union Single Market countries.

METHODS

Four peer-reviewed and eight grey literature databases were searched for quantitative and qualitative literature from 2007 to 2017. Access was categorised according to Penchansky and Thomas' framework and descriptive analyses were conducted. Quality of studies was assessed by the Newcastle-Ottawa scale and the Critical Appraisal Skills Programme checklist.

RESULTS

Twenty-seven articles were included. The findings suggest inadequate MHPSS utilisation. Major barriers to accessing care included language, help-seeking behaviours, lack of awareness, stigma, and negative attitudes towards and by providers.

CONCLUSIONS

Refugees and asylum seekers have high mental health needs but under-utilise services in European host countries. This underutilisation may be explained by cultural-specific barriers which need to be tackled to increase treatment demand. Training health providers on cultural models of mental illness may facilitate appropriate identification, referral, and care. Based on these findings, it is crucial to review policies regarding MHPSS provision across the EU.

Mental health care for adult refugees in high-income countries

Approximately one-third of people who have obtained refugee status live in high-income countries. Over recent years, the number of refugees has been increasing, and there are questions on how many of them need mental health care and which type of interventions are beneficial. Meta-analyses showed highly variable rates of mental disorders in adult refugees. This variability is likely to reflect both real differences between groups and contexts, and methodological inconsistencies across studies. Overall prevalence rates after resettlement are similar to those in host populations. Only post-traumatic stress disorder (PTSD) is more prevalent in refugees. In long-term resettled refugees, rates of anxiety and depressive disorders are higher and linked to poor social integration. Research on mental health care for refugees in high-income countries has been extensive, but often of limited methodological quality and with very context-specific findings. The existing evidence suggests several general principles of good practice: promoting social integration, overcoming barriers to care, facilitating engagement with treatment and, when required, providing specific psychological treatments to deal with traumatic memories. With respect to the treatment of defined disorders, only for the treatment of PTSD there has been substantial refugee-specific research. For other diagnostic categories, the same treatment guidelines apply as to other groups. More systematic research is required to explore how precisely the general principles can be specified and implemented for different groups of refugees and in different societal contexts in host countries, and which specific interventions are beneficial and cost-effective. Such interventions may utilise new communication technologies. Of particular importance are long-term studies to identify when mental health interventions are appropriate and to assess outcomes over several years. Such research would benefit from sufficient funding, wide international collaboration and continuous learning over time and across different refugee groups.

Prevalence of and risk factors for mental disorders in refugees

Given the increasing numbers of refugees worldwide, the prevalence of their mental disorders is relevant for public health. Prevalence studies show that, in the first years of resettlement, only post-traumatic stress disorder (PTSD) rates are clearly higher in refugees than in host countries' populations. Five years after resettlement rates of depressive and anxiety disorders are also increased. Exposure to traumatic events before or during migration may explain high rates of PTSD. Evidence suggests that poor social integration and difficulties in accessing care contribute to higher rates of mental disorders in the long-term. Policy and research implications are discussed.

The use of psychiatric services by young adults who came to Sweden as teenage refugees: a national cohort study

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.

What do register-based studies tell us about migrant mental health? A scoping review

BACKGROUND

Previous studies investigating the mental health of migrants have shown mixed results. The increased availability of register data has led to a growing number of register-based studies in this research area. This is the first scoping review on the use of registry and record-linkage data to examine the mental health of migrant populations. The aim of this scoping review is to investigate the topics covered and to assess the results yielded from these studies.

METHODS

We used a scoping review methodology to search MedLine, PubMed, PsychINFO, Web of Science, and SCOPUS for all register-based studies on the mental health of migrants. Two reviewers screened all papers, independently, using iteratively applied inclusion and exclusion criteria. Using gradually broadening inclusion and exclusion criteria for maximum "scope," newly published criteria developed to appraise the methodological quality of record-linkage studies were applied to eligible papers and data were extracted in a charting exercise.

RESULTS

A total of 1309 papers were screened and appraised, 51 of which met the eligibility and quality criteria and were included in the review. This review identified four major domains of register-based research within the topic of migrant mental health: rates and risks of psychiatric disorders, rates and risks of suicide mortality, the use of psychotropic drugs, and health service utilisation and mental health-related hospitalisation rates. We found that whilst migrants can be at an increased risk of developing psychotic disorders and suicide mortality, they are less likely to use psychotropic medication and mental health-related services.

CONCLUSIONS

This review systematically charts the register-based studies on migrants' mental health for the first time. It shows the main topics and gaps in knowledge in this research domain, discusses the disadvantages of register-based studies, and suggests new directions for forthcoming studies.

Hospital Admission and Criminality Associated with Substance Misuse in Young Refugees - A Swedish National Cohort Study

Background

High rates of mental health problems have been described in young refugees, but few studies have been conducted on substance misuse. This study aimed to investigate the patterns of hospital care and criminality associated with substance misuse in refugees who settled in Sweden as teenagers.

Methods

Gender stratified Cox regression models were used to estimate the risks of criminal convictions and hospital care associated with substance misuse from national Swedish data for 2005–2012. We focused on 22,992 accompanied and 5,686 unaccompanied refugees who were aged 13–19 years when they settled in Sweden and compared them with 1 million native Swedish youths from the same birth cohort.

Results

The risks of criminal conviction associated with substance misuse increased with the length of residency in male refugees, after adjustment for age and domicile. The hazard ratios (HRs) were 5.21 (4.39–6.19) for unaccompanied and 3.85 (3.42–4.18) for accompanied refugees after more than 10 years of residency, compared with the native population. The risks were slightly lower for hospital care, at 2.88 (2.18–3.79) and 2.52(2.01–3.01) respectively. Risks were particularly pronounced for male refugees from the Horn of Africa and Iran. The risks for all male refugees decreased substantially when income was adjusted for. Young female refugees had similar risks to the general population.

Conclusion

The risks of criminality and hospital care associated with substance misuse in young male refugees increased with time of residency in Sweden and were associated with a low level of income compared with the native Swedish population. Risks were similar in accompanied and unaccompanied refugees.

Prenatal parental depression and preterm birth: a national cohort study

Objective

To investigate the effects of maternal and paternal depression on the risk for preterm birth.

Design

National cohort study.

Setting

Medical Birth Register of Sweden, 2007–2012.

Population

A total of 366 499 singleton births with linked information for parents’ filled drug prescriptions and hospital care.

Methods

Prenatal depression was defined as having filled a prescription for an antidepressant drug or having been in outpatient or inpatient hospital care with a diagnosis of depression from 12 months before conception until 24 weeks after conception. An indication of depression after 12 months with no depression was defined as ‘new depression’, whereas all other cases were defined as ‘recurrent depression’.

Main outcome measures

Odds ratios (ORs) for very preterm (22–31 weeks of gestation) and moderately preterm (32–36 weeks of gestation) births were estimated using multinomial logistic regression models.

Results

After adjustment for maternal depression and sociodemographic covariates, new paternal prenatal depression was associated with very preterm birth [adjusted OR (aOR) 1.38, 95% confidence interval (95% CI) 1.04–1.83], whereas recurrent paternal depression was not associated with an increased risk of preterm birth. Both new and recurrent maternal prenatal depression were associated with an increased risk of moderately preterm birth (aOR 1.34, 95% CI 1.22–1.46, and aOR 1.42, 95% CI 1.32–1.53, respectively).

Conclusions

New paternal and maternal prenatal depression are potential risk factors for preterm birth. Mental health problems in both parents should be addressed for the prevention of preterm birth.

Tweetable abstract

Depression in both mothers and fathers is associated with an increased risk of preterm birth.

Depression in both mothers and fathers is associated with an increased risk of preterm birth.

The Effects of the Urban Built Environment on Mental Health: A Cohort Study in a Large Northern Italian City

Mental health (MH) has a relevant burden on the health of populations. Common MH disorders (anxiety and non-psychotic depression) are well associated to socioeconomic individual and neighborhood characteristics, but little is known about the influence of urban structure. We analyzed among a Turin (Northwest Italy) urban population the association at area level of different urban structure characteristics (density, accessibility by public transport, accessibility to services, green and public spaces) and consumption of antidepressants. Estimates were adjusted by individual socio-demographic variables (education, housing tenure, employment) and contextual social environment (SE) variables (social and physical disorder, crime rates). Data was extracted from the Turin Longitudinal Study (TLS)-a census-based cohort study following up prospectively the mortality and morbidity of the population. As expected, individual characteristics show the strongest association with antidepressant drug consumption, while among built environment (BE) indicators accessibility by public transport and urban density only are associated to MH, being slightly protective factors. Results from this study, in agreement with previous literature, suggest that BE has a stronger effect on MH for people who spend more time in the neighborhood. Therefore, this research suggests that good accessibility to public transport, as well as a dense urban structure (versus sprawl), could contribute to reduced risk of depression, especially for women and elderly, by increasing opportunities to move around and have an active social life.

Access to mental health services and psychotropic drug use in refugees and asylum seekers hosted in high-income countries

In the populations of refugees and asylum seekers hosted in high-income countries, access to mental health care and psychotropic drugs, is a major challenge. A recent Swedish cross-sectional register study has explored this phenomenon in a national cohort of 43 403 young refugees and their families from Iraq, Iran, Eritrea, Ethiopia, Somalia and Afghanistan. This register study found lower rates of dispensed psychotropic drugs among recently settled refugees, as compared with Swedish-born residents, with an increase in the use with duration of residence. In this commentary, the results of this survey are discussed in view of their global policy implications for high-income countries hosting populations of refugees and asylum seekers.
