Background

In recent decades, Sweden has become an increasingly diverse society by origin, but one in which residential segregation by migrant background has also increased. This study examines how different aspects of migrant residential segregation are associated with all-cause mortality among native-born and migrant populations.

Methods Using Swedish population-based registers, this longitudinal open cohort study assessed associations between four local level indices of migrant residential segregation and all-cause mortality among adult migrant and native-born residents of Sweden's three largest metropolitan areas (Stockholm, Gothenburg, and Malmö) between 2004 and 2016. Multilevel Poisson regression models, adjusted for individual-level sociodemographic and socioeconomic factors as well as area-level socioeconomic conditions, were used to estimate associations between these indices and all-cause mortality.

Results

Moderate decreased mortality risks were observed among migrants in residential areas with higher levels of migrant density, isolation, and exposure in fully adjusted models. However, isolation and exposure effects could not be distinguished due to a high degree of correlation between the isolation and exposure measures. In fully adjusted models mortality gradients were largely unobserved among native-born individuals in relation to migrant residential segregation. The evenness dimension of segregation showed limited relevance for mortality risk in both groups.

Conclusions

This study provides evidence that higher migrant density is associated with lower mortality risks among migrants, suggesting that residential areas with higher proportions of migrants may offer health benefits for migrants. These findings highlight the importance of residential contexts in shaping migrant health outcomes.

Introduction: Sweden, with its history of restrictive alcohol policies and a large and diverse migrant population, constitutes an interesting context for studies on alcohol consumption patterns in migrant groups. This study examines how hazardous drinking among migrants in Sweden varies by origin, duration of residence and age at migration.

Methods: Pooled cross-sectional survey data from the Västra Götaland region of Sweden, collected in 2011 and 2015, were linked to register data containing demo-graphic, socioeconomic and migration-related factors (i.e., country of birth, duration of residence, age at migration), for 7754 migrants and 68,493 Swedish-born individuals aged 18–84 years. Logistic regression analyses were applied to estimate odds ratios (OR) and 95% confidence intervals (CI) for hazardous drinking, identified by the validated Alcohol Use Disorders Identification Test.

Results: Relative to Swedish-born individuals, migrants from other Nordic countries had higher odds of hazardous drinking (OR 1.45, 95% CI 1.18–1.77), while migrants from other European (OR 0.55, 95% CI 0.44–0.69) and non-European (OR 0.25, 95% CI 0.20–0.31) countries showed lower likelihoods. Among non-Nordic migrants in particular, hazardous drinking was more common among those with a longer duration of residence and those who migrated at pre-school ages.

Discussion and Conclusions: Hazardous drinking among non-Nordic migrants increasingly resembled that of the Swedish-born population over time, aligning with findings in less restrictive alcohol policy contexts. Understanding how drinking patterns vary among migrant groups over time and across policy contexts is essential for developing effective public health strategies to reduce hazardous consumption and associated health and social harms.

Background  Parental leave generosity is protective for mothers’ mental health in the postpartum period and beyond. Strong work requirements exist for parents in Sweden to receive more generous benefits which might penalise individuals who, due to poor health, have a weak labour market attachment. The aim of the study was to examine whether mothers with poor health prior to pregnancy are less likely to be eligible for more generous benefits in Sweden.

Methods  We used total population registers to study first-time mothers, aged 25–45 years, who were resident in Sweden and gave birth between 1 January 2009 and 30 September 2013 (n = 151,452). We used logistic regression to examine the association between health one and two consecutive years prior to pregnancy (to assess chronicity) and eligibility for earnings-related parental leave benefits.

Results  Mothers who were admitted to hospital or received specialist outpatient care for any health condition in the year prior to pregnancy were less likely to be eligible for earnings-related benefits (OR 0·79, 95%CI 0·76–0·83) compared to healthy mothers, particularly those with chronic health issues (OR 0·64, 95%CI 0·62–0·68). Findings were driven by mothers with mental disorders (OR 0·22, 95%CI 0·20–0·23 for the year before pregnancy), and associations were stronger for those with chronic health issues and for Swedish-born mothers.

Conclusion  Mothers with prior health conditions, particularly mental disorders, are less likely to benefit from the protective health effect of parental leave as they may not meet the eligibility requirements for more generous remunerations. This study highlights how the strong work requirement for accessing generous parental leave benefits could unintentionally exacerbate socioeconomic inequalities between mothers with and without poor mental health. Easing work requirements for eligibility to more generous parental leave remuneration could help reduce these inequalities and thus promote better mental health for all, particularly among more disadvantaged groups. As such, our findings empirically support the need for adopting the Health in All Policies framework when designing parental leave policies in order to minimise health inequalities.

Children of immigrants born in the host country–the second generation (G2)–face higher risks of unemployment and overqualification compared to the majority native population in Western Europe. While the health effects of unemployment and overqualification are well documented, it remains unclear whether these factors impact the mental health of the G2 in the same way as in the majority population. This study uses Swedish register data to examine the association between different labor market disadvantages, i.e., unemployment and overqualification, and mental health outcomes among the G2 and the majority population. The outcome was measured as time to the first prescription of psychotropic medications (anxiolytics, sedatives, hypnotics, and antidepressants). Descriptive findings showed that psychotropic prescription rates are higher among G2 groups compared to the majority population. Cox proportional hazards models, adjusted for demographic and socioeconomic factors, indicated that unemployment similarly impacts mental health across origin groups, suggesting that being unemployed does not contribute to the mental health inequality between the G2 and the majority population. G2 individuals, especially G2 European individuals, showed higher risks of psychotropic prescriptions across all employment types. These findings imply that improving the labor market position is not sufficient to address mental health inequalities between the G2 and the majority population.

Aims: We examined the patterns of healthcare utilisation for drug use disorders (DUDs) and charges related to narcotics among young refugees in Norway considering the role of sex, country of origin and condition of arrival (accompanied versus unaccompanied minors).

Methods: Based on national registers, sex-stratified Cox regression models were used to estimate hazard ratios to assess the risk of being charged with a narcotics offence and the use of healthcare services related to DUDs. The sample consisted of 15,068 young refugees and 573,241 young Norwegians born in Norway to two Norwegian-born parents. All of the young people in the sample were born between 1983 and 1994. The follow-up period was from January 2008 to December 2015.

Results: Compared with their Norwegian peers, both male and female refugees showed either a similar or lower risk of receiving healthcare for DUDs. However, male refugees showed an increased risk of being charged with a narcotic offence, except those from Afghanistan and the former Yugoslavia. Accompanied male refugees were at a higher risk of being charged, while unaccompanied male refugees showed a lower risk.

Conclusions: Young male refugees generally had a higher risk of being charged for narcotic offences while showing a similar risk of receiving healthcare for DUDs compared to Norwegian-born young people. However, young men from Afghanistan and the former Yugoslavia deviated from this pattern. This may be partially explained by the length of time spent in Norway. The results add support to previous qualitative studies suggesting that punitive drug policies may disproportionately affect men from minority groups. Further research controlling for parental household-level factors is warranted.

Aims: This study aimed at comparing several health outcomes in young adulthood among child refugees who settled in the different immigration and integration policy contexts of Denmark, Norway and Sweden. Methods: The study population included refugees born between 1972 and 1997 who immigrated before the age of 18 and settled in the three Nordic countries during 1986-2005. This population was followed up in national registers during 2006-2015 at ages 18-43 years and was compared with native-born majority populations in the same birth cohorts using sex-stratified and age-adjusted regression analyses. Results: Refugee men in Denmark stood out with a consistent pattern of higher risks for mortality, disability/illness pension, psychiatric care and substance misuse relative to native-born majority Danish men, with risk estimates being higher than comparable estimates observed among refugee men in Norway and Sweden. Refugee men in Sweden and Norway also demonstrated increased risks relative to native-born majority population men for inpatient psychiatric care, and in Sweden also for disability/illness pension. With the exception of increased risk for psychotic disorders, outcomes among refugee women were largely similar to or better than those of native-born majority women in all countries. Conclusions: The observed cross-country differences in health indicators among refugees, and the poorer health outcomes of refugee men in Denmark in particular, may be understood in terms of marked differences in Nordic integration policies. However, female refugees in all three countries had better relative health outcomes than refugee men did, suggesting possible sex differentials that warrant further investigation.

Background: Studies of migration and health have hypothesized that immigrants may emigrate when they develop poor health (salmon bias effect), which may partially explain the mortality advantage observed among immigrants in high-income countries. We evaluated the salmon bias effect by comparing the health of immigrants in Sweden who emigrated with those who remained, while also exploring potential variation by macro-economic conditions, duration of residence and region of origin. Methods: A longitudinal, open cohort study design was used to assess risk of emigration between 1992 and 2016 among all adult (18+ years) foreign-born persons who immigrated to Sweden between 1965 and 2012 (n = 1 765 459). The Charlson Comorbidity Index was used to measure health status, using information on hospitalizations from the Swedish National Patient Register. Poisson regression models were used to estimate incidence rate ratios (RRs) with 95% confidence intervals (CIs) for emigrating from Sweden. Results: Immigrants with low (RR = 0.83; 95% CI: 0.76-0.90) moderate (RR = 0.70; 95% CI: 0.62-0.80) and high (RR = 0.62; 95% CI: 0.48-0.82) levels of comorbidities had decreased risk of emigration relative to those with no comorbidities. There was no evidence of variation by health status in emigration during periods of economic recession or by duration of residence. Individuals with low to moderate levels of comorbidities from some regions of origin had an increased risk of emigration relative to those with no comorbidities. Conclusions: The study results do not support the existence of a salmon bias effect as a universal phenomenon among international immigrants in Sweden.

Within the past few decades, the academic discipline of public health has taken root in universities around the world. As a young and multidisciplinary field with a dual-research/practice focus and a tradition that emphasises method development, the use of theory in public health research has often been neglected. In this article, we argue that explicit utilisation of theory is crucial to further the development of public health as an academic discipline. By examining three core areas of academic activity at universities—education, research and public outreach—we illustrate the role theory plays in establishing public health as an independent research discipline. We discuss the importance and benefits of including theoretical reasoning in teaching, research articles and communication with non-academic audiences. We also highlight the role of postgraduate students and junior researchers who, thanks to a combination of experience and receptiveness, play an important role in developing public health theory. We believe that a key to a successful process of establishing public health as an academic discipline lies in the development of a transdisciplinary approach to the research subject. This will equip public health researchers with appropriate tools to take on the public health challenges of the future.

With labor being a central social determinant of health, there is an increasing need to investigate health inequalities within the heterogenous and growing population in self-employment. This study aimed to longitudinally investigate the relationship between income level, self-employment status and multiple work-related health indicators in a Swedish national cohort (n = 3,530,309). The study investigated the relationship between self-employment status and health outcomes later in life. All poor health outcomes, with the exception of alcohol-related disorders, were more common in the self-employed population, compared to the group in regular employment. The income gradient, however, was more pronounced in the group with regular employment than the groups in self-employment. The study found clear connections between low income and poor health in all employment groups, but the gradient was more pronounced in the group in regular employment. This suggests that income has a weaker connection to other types of health promoting resources in the self-employed population. Potentially, lacking social and public support could make it difficult for unhealthy individuals to maintain low-income self-employment over a longer time period.

Introduction Sweden has long been praised for a generousparental leave policy oriented towards facilitating a genderequitable approach to work and parenting. Yet certain aspects of Swedish parental leave could also be responsible for the maintenance of (or even the increase in) health inequalities. Using a ‘Health in All Policies’ lens, this research project aims to assess the unintended health consequences of various components of Sweden’s parental leave policy, including eligibility for and uptake of earnings based benefits.

Methods and analysis We will use individual-level data from multiple Swedish registers. Sociodemographic information, including parental leave use, will be retrieved from the total population register, Longitudinal Integration Database for Health Insurance and Labour Market Studies and Social Insurance Agency registers. Health information for parents and children will be retrieved from the patient, prescribed drug, cause of death, medical birth and children’s health registers. We will evaluate parents’ mental, mothers’ reproductive and children’s general health outcomes in relation to several policy reforms aiming to protect parental leave benefits in short birth spacing (the speed premium) and to promote father’s uptake (the father’s quota) and sharing of parental leave days (the double days reform). We will also examine effects of increases in basic parental leave benefit levels. Using quasi-experimental designs, we will compare health outcomes across these reforms and eligibility thresholds with interrupted time series, difference-in-difference and regression discontinuity approaches to reduce the risk of health selection and assess causality in the link between parental leave use and health.
