How can we help doctors stay in rural areas of Japan? A comparison in medical students' attitudes toward general practice and clinical research of a medical school in Japan and in Sweden.

Objective: In Sweden, primary healthcare centers play an important role in the performance of general practice, education, and clinical research. In Japan, general physicians or general practitioners are expected to be more active in the small-scale hospitals and clinics in rural areas. This study aimed to explore the differences in attitudes toward general practice and clinical research among medical students in Japan and Sweden to present solutions to help doctors stay in rural areas of Japan. Materials and Methods: This cross-sectional study was conducted at two medical schools in Japan and Sweden in 2018, using an anonymous and self-administered questionnaire survey that comprised 16 items including 9 items on clinical research. Results: Participants were 154 medical students (response rate: 69.4% for 222 students) in Japan and 56 (27.1% for 201 students) in Sweden. The proportion of medical students who wanted to become general physicians was greater in Japan than in Sweden (Japan:Sweden=36.4%:17.9%; P=0.012). Although fewer Japanese students wanted to conduct research in rural areas than Swedish students (43.5%:57.1%; P<0.001), the positive proportion of Japanese students working in clinical research and/or taking an academic degree in rural areas was greater than that of Swedish students (52.0%:23.2%; P=0.032). Conclusion: As Swedish medical students and young doctors learn considerably from primary healthcare centers, their attitudes toward clinical research are more developed than those of their Japanese counterparts. However, more Japanese medical students than Swedish students wish to become general practitioners, and they are likely to strive to conduct clinical research at small-scale hospitals/clinics in rural areas. Therefore, the improvement of the clinical research environment in small-scale hospitals and clinics in rural areas is needed at the earliest in Japan.

"Nerves Need Nourishment": Advertising Phospho-Energon Pills in Early Twentieth-Century Sweden.

This paper offers the first case study of Phospho-Energon - an early twentieth-century Swedish patent medicine believed to cure nervousness. Using a large dataset of newspaper advertisements, it explores how the product was presented through scientific and medical language, which drew upon a range of visual and verbal rhetoric to convince consumers of its benefits. It finds that pseudoscientific discourse focusing on self-help was regularly used to sell Phospho-Energon, with consumers warned that their nerves were "not allowed to fail" and required "protection" in order to remain healthy. Furthermore, the "science" supporting this discourse gradually shifted over time as neurosis replaced neurasthenia as a diagnostic category and the concept of spring lethargy became popularised. Overall, this study argues that Phospho-Energon stands as an important example of how partial scientific/medical claims can be used as a rhetorical device to sell products to consumers looking for a quick-fix cure for their perceived mental health conditions.

Benefits and costs of measures to tackle the outbreak of African swine fever in Sweden.

A common rule in many countries for mitigating the damage caused by African swine fever (ASF) is to eradicate the virus at the outbreak in order to prevent its dispersal and the associated social costs of depopulating infected domestic pigs. The economic performance of this practice, as measured by five different evaluation criteria (net present value, benefit-cost ratio, rate of return, internal rate of return, and payback time), depends on the type of control cost and the spatial and dynamic allocation of benefits, i.e. avoided losses from infected domestic pig farms. The present paper calculates the direct and indirect costs of immediate control measures during an ASF outbreak in wild boars in Mid Sweden. The direct costs include expenses incurred for surveillance, laboratory tests, depopulation of wild boar etc., while the indirect costs are borne by firms and people in the area in relation to movement restrictions. The calculations showed that the total cost of control measures amounted to 28 million euros, with indirect costs making up 40 % of this figure. The benefits were greatly dependent on the speed of ASF dispersal and assumptions about pig farmers' investment responses, which implied large variations in each of the five evaluation criteria.

The COVID-19 pandemic caused gender-specific declines in knee surgery rates in Sweden from 2020 to 2021.

Purpose: Changes in knee surgery incidence are important factors for stakeholders and healthcare providers. The aim of this study was to examine trends and patterns in knee surgeries in Sweden from 2010 to 2022. The study focuses on gender-specific and overall rates of knee surgeries. Methods: The analysis is based on a data set sourced from national healthcare records. The data was stratified based on surgical rates and categorized by gender, year and the specific knee arthroplasty technique used. We tracked year-to-year changes in surgical rates to identify overarching patterns. We used Poisson regression to predict future trends. Comparisons were made between various surgical subcategories, such as those with and without cement in knee arthroplasty surgeries. Results: In 2010, the rate of knee surgeries per 100,000 person-years was 518.7 for males and 448.0 for females. These rates exhibited fluctuations over time, reaching their lowest point in 2020, attributed to the pandemic's disruption of elective procedures, with 386.4 surgeries per 100,000 males and 386.3 surgeries per 100,000 females. A resurgence was observed in 2022. The rates of primary knee arthroplasty increased, with a male rate of 106.2 and a female rate of 150.7 surgeries per 100,000 inhabitants in 2010, rising to 126.8 for males and 166.2 for females in 2022. Conclusion: This comprehensive nationwide open-source data analysis of knee surgeries in Sweden shows that the COVID-19 pandemic significantly impacted knee surgery rates in Sweden, causing a notable decline in 2020, followed by a resurgence in 2022. Furthermore, while men had higher surgery rates than women, they experienced a larger decline in the incidence of knee surgeries compared to women. Understanding these trends is crucial for stakeholders and healthcare providers to improve resource allocation, address gender disparities, and maintain the resilience of surgical services in the face of disruptions. Level of Evidence: Level III.

Disparities in overall and site-specific cancer mortality among immigrant generations in Sweden: A nationwide follow-up study over three decades.

We examined the overall and site-specific cancer mortality disparities among first-generation - separately in adults (G1) and children (G1.5) at immigration - and second-generation (G2) immigrants and their countries of origin using population-based registries in Sweden, encompassing over 8.5 million individuals aged 20 and above residing in Sweden since 1990, with follow-up until December 31, 2023. Cox proportional hazard models were fitted, stratified by gender, to estimate hazard ratios and 95% confidence intervals compared to natives. Mortality rates for most cancers transitioned from lower in G1 towards the rate of natives in G2. However, elevated mortality rates were sustained across generations for liver cancer in males and stomach cancer in females. Among G2, mortality from lymphohematopoietic cancers in males, and lung and cervix uteri cancers in females were elevated - by 10%, 9%, and 17% respectively compared to natives. Country of origin analyses revealed substantial disparities. For instance, G2 females with Nordic parental origin had a 13% higher risk of death from lung cancer, while those with non-Western parental origin had a 54% lower risk as compared to natives. These findings suggest a generational and arrival-age dynamics of cancer mortality and highlight target groups for cancer prevention and control among immigrants.

Neoadjuvant chemotherapy in relation to long-term mortality in individuals cured of gastric adenocarcinoma.

BACKGROUND: Late effects of chemotherapy could affect mortality amongst cancer survivors. This study aimed to clarify if neoadjuvant chemotherapy for gastric adenocarcinoma influences the long-term survival in individuals cured of this tumour. METHODS: This was a nationwide and population-based cohort study that included all individuals who underwent gastrectomy for gastric adenocarcinoma in Sweden between 2006 and 2015 and survived for ≥ 5 years after surgery. The cohort was followed up until death or end of study period (31 December 2020). Multivariable Cox proportional hazards regression was used to provide hazard ratios (HR) with 95% confidence intervals (CI). The HR were adjusted for age, sex, comorbidity, education, calendar year, tumour sub-location, in-hospital complications, and splenectomy. Data came from medical records and nationwide registers. RESULTS: Amongst 613 gastric adenocarcinoma survivors, neoadjuvant chemotherapy (used in 269 patients; 43.9%) was associated with a decreased crude mortality rate (HR 0.66, 95% CI 0.46-0.96). However, the association attenuated and became statistically non-significant after adjustment for all confounders (HR 0.83, 95% CI 0.56-1.23) and after adjustments solely for age and comorbidity (HR 0.82, 95% CI 0.56-1.20). Stratified analyses did not reveal any statistically significant associations between neoadjuvant chemotherapy and long-term mortality in categories of age, sex, comorbidity, calendar year and tumour sub-location. CONCLUSION: Neoadjuvant chemotherapy did not decrease the long-term survival amongst gastric adenocarcinoma survivors. Patients who received neoadjuvant chemotherapy were a selected group characterised by younger age and fewer severe comorbidities and therefore with better chances of long-term survival.

Perceived discrimination and refraining from seeking physician's care in Sweden: an intersectional analysis of individual heterogeneity and discriminatory accuracy (AIHDA).

BACKGROUND: Discrimination may further impede access to medical care for individuals in socially disadvantaged positions. Sociodemographic information and perceived discrimination intersect and define multiple contexts or strata that condition the risk of refraining from seeking physician's care. By applying analysis of individual heterogeneity and discriminatory accuracy (AIHDA) we aimed to improve the mapping of risk by considering both strata average risk differences and the accuracy of such strata risks for distinguishing between individuals who did or did not refrain from seeking physician's care. METHODS: We analysed nine annual National Public Health Surveys (2004, 2007-2014) in Sweden including 73,815 participants. We investigated the risk of refraining from seeking physician's care across 64 intersectional strata defined by sex, education, age, country of birth, and perceived discrimination. We calculated strata-specific prevalences and prevalence ratios (PR) with 95% confidence intervals (CI), and the area under the receiver operating characteristic curve (AUC) to evaluate the discriminatory accuracy (DA). RESULTS: Discriminated foreign-born women aged 35-49 with a low educational level show a six times higher risk (PR = 6.07, 95% CI 5.05-7.30) than non-discriminated native men with a high educational level aged 35-49. However, the DA of the intersectional strata was small (AUC = 0.64). Overall, discrimination increased the absolute risk of refraining from seeking physician's care, over and above age, sex, and educational level. CONCLUSIONS: AIHDA disclosed complex intersectional inequalities in the average risk of refraining from seeking physician's care. This risk was rather high in some strata, which is relevant from an individual perspective. However, from a population perspective, the low DA of the intersectional strata suggests that potential interventions to reduce such inequalities should be universal but tailored to the specific contextual characteristics of the strata. Discrimination impairs access to healthcare.

Who is Getting the Message? Sociodemographic Factors and Gambling Behavior Associated with Awareness of the Swedish National Self-Exclusion Registry Spelpaus.se.

Awareness and utilization of health interventions can be influenced by sociodemographic factors. These factors play a role in information processing, particularly regarding health messaging. The aim of this study is to analyze how different sociodemographic factors and gambling behaviors are associated with awareness of a (Swedish) gambling self-exclusion register. The study used data from the Swedish longitudinal gambling study (Swelogs) and analyzed n = 6720 participants from a stratified random sample of the Swedish population aged 18-84 years. Logistic regressions were conducted to analyze associations between sociodemographic characteristics, gambling behavior and awareness. Males with middle (OR = 1.70, 95% CI = 1.32-2.19) and high income (OR = 1.58, 95% CI = 1.19-2.09) and females with high (OR = 1.35, 95% CI = 1.03-1.76) and middle-level education (OR = 1.35, CI = 1.04-1.76), had higher awareness of Spelpaus.se. Online gamblers with problematic gambling behavior were three times (OR = 3.69, 95% CI = 2.15-6.37) more likely to be aware than non-gamblers. Online gamblers born in Sweden were twice (OR = 1.95, 95% CI = 1.19-3.19) as likely to be aware compared to those born outside of Europe. Males with high level of awareness had higher PGSI scores compared to women. Education could increase awareness of potential health risks and opportunities for intervention, particularly among women. Future interventions should be tailored to cater to the specific needs of individuals with lower levels of awareness, to facilitate enhancing their awareness and ultimately promoting a more equitable utilization of self-exclusion measures.

A descriptive epidemiological study of the prevalence of self-reported sensory difficulties by age group, sex, education, disability, and migration status in Sweden in 2020.

BACKGROUND: The objective of this study is to estimate the prevalence of self-reported hearing difficulties, vision difficulties and combined vision and hearing difficulties in a Swedish adult population that varies according to migration status, sex, age, disability measured by ADL and IADL and educational attainment level. METHODS: The study utilised data from the Survey of Health, Ageing and Retirement in Europe, which consisted of 2257 individuals aged 60 and above that were interviewed in Sweden in the 2019/2020, SHARE wave 8. To determine the prevalence of sensory difficulties (hearing, vision and dual-sensory difficulties) among various subgroups of the population, a multinomial logistic regression was used. The results of these analyses are presented in terms of predicted probabilities. RESULTS: The study findings indicate that foreign-born older adults experience a lower prevalence of visual difficulties (6.2% [3.3-11.5] in comparison to their Swedish-born counterparts. Moreover, older adults with higher levels of education tend to report a lower prevalence of sensory difficulties overall. Furthermore, sex differences are apparent, with males reporting a higher prevalence of hearing difficulties (18.9% [15.5-22.8] vs. 12.8% [10.7-15.3]) and females reporting a higher prevalence of vision difficulties (12.7% [10.7-15.1] vs. 8.5%[6.8-10.5]). CONCLUSION: The findings highlight disparities in the prevalence and type of perceived sensory difficulties experienced by older adults, by factors such as age, sex, education and migration status. It is important to consider these demographic factors in healthcare planning and interventions aimed at mitigating sensory difficulties in the older population.

If there had been no snus in Sweden: the impact of snus on mortality attributable to smoking.

In Sweden, there has been a massive transition from cigarette smoking to snus, the Swedish kind of low-toxicity oral tobacco. This product poses very little health risk compared to cigarettes, as illustrated by the fact that males in Sweden have Europe's lowest level of mortality attributable to smoking. The current investigation estimates how high the smoking-attributable mortality in Sweden would have been if there had been no snus in Sweden. It is made up by comparisons between observed Swedish data and two scenarios without snus: a group of comparable countries, and, a hypothetical Sweden with no snus use. Both comparisons suggest that around 3000 lives per year have been saved by the use of snus in Sweden.

Arts, culture and sports engagement and self-rated health: a cross-sectional population-based study in southern Sweden.

BACKGROUND: International research demonstrates an association between arts and culture activities and health and wellbeing. A similar association exists for sports event attendance and health. The aim of this study was to investigate associations between arts and culture engagement and attending sports events during the past year and self-rated health (SRH). METHODS: A cross-sectional study. A public health survey with three reminders was sent to a stratified random sample of the adult 18-84 population in Scania in the southernmost part of Sweden in October-December 2019. The weighted response rate was 44%, and 40,087 total respondents were included in the present study. Analyses were performed in logistic regression models with multiple adjustments for age, education, country of birth, leisure-time physical activity (LTPA), smoking, alcohol consumption, and economic stress. RESULTS: The prevalence of poor SRH was 32.8% among women and 27.6% among men. The prevalence of theatre/cinema attendance was 63.2% among women and 55.2% among men, arts exhibition/museum attendance was 41.0% among women and 36.0% among men, and for sports attendance it was 33.8% among women and 48.2% among men. All items included in the final models showed statistically significant associations with self-rated health in bivariate logistic regression models. In the multiple model, adjusted for all covariates including both men and women, the odds ratios (ORs) of poor SRH were statistically significant OR 1.21 (95% confidence interval: 1.14-1.29) for not visiting theatre/cinema during the past year, OR 1.11 (1.04-1.17) for not visiting arts exhibition and OR 1.31 (1.24-1.39) for not visiting a sports event. CONCLUSIONS: Significant associations between arts and culture engagement and sports event attendance, and SRH were observed, although effect measures were comparatively low for arts and cultural engagement. The results may be useful for informing public health promotion and prevention strategies.

Home Care Nurses at the Heart of the Communication Web: Communication Synchronicity and Effects on the Psychosocial Work Environment.

This qualitative study explores how communication practice affects Swedish home care nurses' psychosocial work environment. Data consisted of interviews and field observations, analyzed from the perspective of Media Synchronicity Theory and the Job-Demand-Control-Support model. Individual home care nurses were found to manage an interorganizational communication web. The results indicated that this web could have a protective function for the nurses. Synchronous communication was found important to control the work situation. Nevertheless, asynchronous communication was enforced when communicating with other health care organizations. This reduced the level of control for the nurses. However, when possible, the nurses also arranged their communication practice to gain control. Thus, local optimization for one group could result in suboptimization for others. We conclude that communication practice should be designed holistically and promote synchronous communication to foster well-functioning interprofessional teamwork and to create a healthy psychosocial work environment for both home care nurses and their collaborators.

Awareness and utilization of Swedish youth clinics among migrants enrolled in Swedish language programmes: a cross-sectional study.

BACKGROUND: Previous research has highlighted inequalities in access to Swedish youth clinics (YCs). These inequalities exist not only between non-migrant and young migrant populations but also within various migrant groups. OBJECTIVES: To assess awareness and utilization of Swedish YCs among migrants enrolled in Swedish language programmes and explore associated factors. METHODS: This cross-sectional study involved 1,112 migrants aged 15-65. The analytical sample included 642 (57%) participants who answered the main outcome question about awareness of YCs. Descriptive statistics, bivariate, and multivariate log-binomial regression analyses using a Bayesian approach were applied to summarize the data and identify factors associated with awareness and utilization of YCs among migrants. RESULTS: The results revealed that 30% of all participants and 40% of the participants aged 15-25 years had heard of YCs. Additionally, 23% of the target group (15-25 years) had ever visited one. During descriptive and bivariate analyses, socio-demographic variations were evident in YCs' awareness and utilization. However, in multivariate analyses, only the associations between awareness and year of arrival, and YCs' utilization and year of arrival and type of residence permit, remained statistically significant. CONCLUSION: This study highlights the level of awareness of YCs among migrants attending Swedish language programmes and their utilization by those aged 15-25 years, potentially impacting their access to crucial services and resources. Targeted interventions and sustainable strategies beyond one-time interventions are essential to address the specific needs of different socio-demographic groups and ensure equitable access to YCs' information and services.

Main findings: This study highlights the level of awareness and utilization of youth clinics among migrants attending Swedish language programmes, revealing socio-demographic disparities across different groups.Added knowledge: Migrant men and unaccompanied minors are more likely to be aware of and use youth clinics than migrant women and those with legal guardians, while recent migrants and those with temporary residence permits are at an increased risk of being unaware of or not utilizing these services.Global health impact for policy and action: Targeted interventions and sustainable strategies, beyond one-time efforts, are essential to address the specific needs of different migrant subgroups and ensure equitable and universal access to crucial information and services related to sexual and reproductive health and rights.

Institutional care and education: circulation of knowledge about epilepsy in Sweden 1915-40.

This article focuses on the circulation of knowledge about epilepsy in Sweden between 1915 and 1940. During the period medical research on epilepsy increased, which simultaneously brought a new degree of specialisation and distinction between branches of medicine. The aim of this article is to study the impact of new medical knowledge about epilepsy on the treatment and education of children with epilepsy in Sweden. In order to concretise the aim, the study focuses on the asylum Margarethahemmet. The key source material consists of Margarethahemmet's annual reports and yearbooks. The minutes of the meetings of the Swedish General Association for the Care of the Feebleminded and Epileptic for the period 1915-1938 have been used as supplementary material. In order to trace the impact of medical discoveries on Margarethahemmet's operations, contemporary scientific articles, mostly from Germany, have also been used. The article demonstrates how new research and new knowledge was sought internationally and nationally, to provide doctors and special teachers at the asylum with a proper knowledge about education, care and treatment for children with epilepsy. The increased understanding of the disease directly impacted the ability of a stigmatized group - people with epileptic disorder - to actively participate in society on the same terms as others.

Strict Danes or relaxed Swedes? Comparing health and daily activities in Sweden and Denmark during the Covid-19 pandemic.

AIMS: Amidst the Covid-19 outbreak in 2020, Denmark and Sweden adopted contrasting strategies despite their many cultural similarities. Denmark swiftly imposed strict governmental restrictions, while Sweden favoured a more gradual, voluntary approach. This study aims to analyse the disparities between the two nations in mental health indicators (depressive symptoms, sleep problems and loneliness), daily activities (shopping, going for a walk, visiting family and meeting other people) and medical care after the Covid-19 outbreak. METHODS: Data from adults aged ⩾50 years in the Survey of Health, Ageing and Retirement in Europe (SHARE) wave 8 (2019/2020) and the two SHARE Covid-19 surveys (summer 2020/2021) were utilised. Multilevel logistic regression models assessed longitudinal and cross-sectional changes in Sweden and Denmark. RESULTS: Both countries witnessed reduced risk of depressive symptoms and sleep problems during summer 2020, albeit with a more significant decline in depressive symptoms observed in Denmark: 17.8% (95% confidence interval (CI) 15.0-20.6) vs. 12.5% (95% CI 9.0-15.9). Swedish respondents were more likely to reduce their daily activities in the summer of 2020 (shopping: odds ratio (OR)=0.45, 95% CI 0.36-0.55; visit family: OR=0.76, 95% CI 0.60-0.97) and less likely to have medical appointments postponed (OR=1.83, 95% CI 1.46-2.28). CONCLUSIONS: Minimal differences were observed between Sweden and Denmark in mental health and daily activities during the pandemic. Despite significant disruption to their daily routines, Scandinavians aged ⩾50 years old demonstrate remarkable resilience.

"It should be hard to be a drug abuser" An evaluation of the criminalization of drug use in Sweden.

BACKGROUND: Drug use was criminalized in Sweden in 1988 with aim of reducing the number of consumers and drug-related risks and harms. Imprisonment was introduced into the penalty scale in 1993 to improve the legislation's effectiveness. The criminalization has never been evaluated. METHOD: Goal-attainment evaluation based on a range of indicators from surveys, case-finding estimates, healthcare and cause-of-death data, and crime statistics. Comparative drug policy analysis is conducted with other Nordic countries. RESULTS: The criminalization is not followed by a reduced or more expensive drug supply, reduced consumption levels, problematic drug use or healthcare needs, or to fewer drug-related deaths. Most of the indicators instead show the opposite. Control costs are high, and trends are no better than those of other Nordic countries, despite Sweden's more repressive drug policy. CONCLUSION: Criminalization emerges as an ineffective, expensive and harmful means of dealing with the drugs problem.

A roadmap for assessing the diagnostic usefulness of neurosensory testing and an updated method for exposure assessment among vibration-exposed workers in northern Sweden.

Workers who use handheld vibrating machines such as grinders, hammers and chainsaws expose themselves to hand-arm vibration (HAV). Exposure to HAV may cause injuries to both the neurological and the vascular system. The occupational health services (OHS) in Sweden use a formal guideline for secondary prevention focusing on early detection of vibration-related injuries. The guide includes several screening tools, such as a screening questionnaire, clinical examinations, and laboratory tests. There are no studies, to our knowledge, on the diagnostic value of the separate items on symptoms in the screening questionnaire in relation to the laboratory tests or the clinical examinations performed during a medical examination among patients exposed to HAV. Furthermore, the recently presented ISO standard for HAV measurements (ISO/TR 18,750) has only been tested for vascular injuries and not neurological injuries. This research roadmap aims to evaluate separate items in a screening questionnaire on neurological symptoms in relation to laboratory and clinical tests among HAV exposed workers in the Arctic region of Northern Sweden. It also covers a comparison of the dose-response of the current ISO 5349-1 measurement standard and the new suggested standard ISO/TR 18,750 with the neurosensory outcomes. This manuscript describes the study rationale, design, methods, and significance.

Survival among patients cured from gastric adenocarcinoma compared to the background population.

BACKGROUND: It is unknown if gastric adenocarcinoma survivors have longer, shorter, or similar survival compared to the background population. This knowledge could contribute to evidence-based monitoring strategies, healthcare recommendations, and information for patients and families. METHODS: This population-based cohort study included all patients who underwent gastrectomy for gastric adenocarcinoma between 2006-2015 in Sweden and survived ≥ 5 years after surgery. They were followed up until death, postoperative year 10, or end of study period (31 December, 2020). Division of the observed by the expected survival yielded relative survival rates with 95% confidence intervals (CIs) using the life table method. The expected survival was derived from the entire Swedish population of the corresponding age, sex, and calendar year. Data came from medical records and nationwide registers. RESULTS: The survival among all 767 gastric adenocarcinoma survivors was shorter than the expected. The reduction in relative survival increased for each follow-up year, from 97.3% (95% CI 95.4-99.1%) year 6 to 86.6% (95% CI 82.3-90.9%) year 10. The decline in relative survival was more pronounced among patients who had gastrectomy in earlier calendar years (82.9% [95% CI 77.4-88.4%] year 10 for years 2011-2015), shorter education (85.2% [95% CI 77.4-93.0%] year 10 for education ≤ 9 years), more comorbidities (78.0% [95% CI 63.9-92.0%] year 10 for Charlson comorbidity score ≥ 2), and no neoadjuvant therapy (83.2% [95% CI 77.4-89.0%] year 10). CONCLUSION: Gastric adenocarcinoma survivors seem to have poorer survival than the corresponding background population, particularly in certain subgroups.

The transmission of social inequalities through economic difficulties and lifestyle factors on body mass index: An intersectional mediation analysis in the Swedish population.

Body mass index (BMI) has increased in Sweden, disproportionally for socially disadvantaged groups, including women, low-educated, and immigrants, who may also face economic constraints, physical inactivity, and poor-quality diets. Intersectional public health research aims to unravel such complex social inequalities, but the intersectional transmission of inequalities to BMI remains unexplored. We aimed to examine intersectional inequalities in BMI mediated by economic strain and health-related lifestyle in the Swedish population. By using the Health on Equal Terms cross-sectional surveys in 2016, 2018, 2020, and 2021 (n = 44,177 inhabitants aged 25 and over), we performed an intersectional mediation analysis to analyze how inequalities across social intersectional strata (by gender, education, and migration status) may be transmitted through economic strain and unhealthy lifestyle (physical inactivity or inadequate fruit/vegetables consumption) to BMI. Our findings showed a sequential transmission that indicates the fact that socially disadvantaged strata (compared with high-educated native men) experienced more economic strain, which in turn led to poorer health-related lifestyles and ultimately to a higher BMI. We also found that certain intersectional strata, such as high-educated women, were more vulnerable to economic strain, despite having lower BMI than high-educated native men. Additionally, the highest BMI and unhealthy lifestyle risk was observed among low- and middle-educated men. In conclusion, not only inequalities in BMI, but also the economic and behavioral pathways underpinning the inequalities, act by intersectional patterns. Public health interventions should provide economic security, particularly for women and migrant population as well as promoting a healthy lifestyle in lower-educated strata, especially among men, to achieve healthy BMI levels.

Global population datasets overestimate flood exposure in Sweden.

Accurate population data is crucial for assessing exposure in disaster risk assessments. In recent years, there has been a significant increase in the development of spatially gridded population datasets. Despite these datasets often using similar input data to derive population figures, notable differences arise when comparing them with direct ground-level observations. This study evaluates the precision and accuracy of flood exposure assessments using both known and generated gridded population datasets in Sweden. Specifically focusing on WorldPop and GHSPop, we compare these datasets against official national statistics at a 100 m grid cell resolution to assess their reliability in flood exposure analyses. Our objectives include quantifying the reliability of these datasets and examining the impact of data aggregation on estimated flood exposure across different administrative levels. The analysis reveals significant discrepancies in flood exposure estimates, underscoring the challenges associated with relying on generated gridded population data for precise flood risk assessments. Our findings emphasize the importance of careful dataset selection and highlight the potential for overestimation in flood risk analysis. This emphasises the critical need for validations against ground population data to ensure accurate flood risk management strategies.
