ABSTRACT

An estimated 14-20% of people infected with COVID-19 require medical care. The aim of the present study was to evaluate physical function, cognitive function, and daily activities in patients hospitalized due to COVID-19, and to investigate differences depending on age and admission to the intensive care unit (ICU). This prospective descriptive cross-sectional study included a consecutive sample of 211 patients (mean age 65.1 years, 67.3% men) hospitalized due to COVID-19 in Sweden. Data regarding physical function and daily activities were collected in hospital from July 2020 to February 2021. The average length of hospital stay was 33.8 days, and 48.8% of the patients were admitted to the ICU. Physical function (grip- and lower body strength) was reduced in both groups, and significantly more in the older group, ≥65 years old, compared to the younger. Furthermore, the older group also had significantly less ability to perform activities in daily life, and had significantly reduced cognitive function as compared to the younger age group. In patients treated in the ICU, physical impairments as well as the activity level were significantly more pronounced compared to patients not treated in the ICU. Patients hospitalized due to COVID-19 are physically impaired, have mild cognitive impairments, and have difficulties performing daily activities. The findings in this study indicate the need for out-patient follow-up and rehabilitation for patients hospitalized due to COVID-19, especially in older patients and patients treated in the ICU.

ABSTRACT

BACKGROUND: Alzheimer's disease (AD) and other dementias currently represent the fifth most common cause of death in the world, according to the World Health Organization, with a projected future increase as the proportion of the elderly in the population is growing. Air pollution has emerged as a plausible risk factor for AD, but studies estimating dementia cases attributable to exposure to fine particulate matter (PM2.5) air pollution and resulting monetary estimates are lacking. METHODS: We used data on average population-weighted exposure to ambient PM2.5 for the entire population of Sweden above 30 years of age. To estimate the annual number of dementia cases attributable to air pollution in the Swedish population above 60 years of age, we used the latest concentration response functions (CRF) between PM2.5 exposure and dementia incidence, based on ten longitudinal cohort studies, for the population above 60 years of age. To estimate the monetary burden of attributable cases, we calculated total costs related to dementia, including direct and indirect lifetime costs and intangible costs by including quality-adjusted life years (QALYs) lost. Two different monetary valuations of QALYs in Sweden were used to estimate the monetary value of reduced quality-of-life from two different payer perspectives. RESULTS: The annual number of dementia cases attributable to PM2.5 exposure was estimated to be 820, which represents 5% of the annual dementia cases in Sweden. Direct and indirect lifetime average cost per dementia case was estimated to correspond € 213,000. A reduction of PM2.5 by 1 µg/m3 was estimated to yield 101 fewer cases of dementia incidences annually, resulting in an estimated monetary benefit ranging up to 0.01% of the Swedish GDP in 2019. CONCLUSION: This study estimated that 5% of annual dementia cases could be attributed to PM2.5 exposure, and that the resulting monetary burden is substantial. These findings suggest the need to consider airborne toxic pollutants associated with dementia incidence in public health policy decisions.

ABSTRACT

BACKGROUND: Lack of control over life situations is an important social determinant that may negatively affect parental and child health. This study took place in an area of Stockholm, Sweden with high indications of socioeconomic disadvantage, a large part of the population with foreign background, as well as higher levels of poor health than the county average. It investigated staff perceptions of pathways from situations of low control, potentially leading to health inequities, affecting families enrolled in an early childhood home visiting programme during the Covid-19 pandemic. METHODS: Semi-structured interviews were carried out with 23 child health care nurses and parental advisors working in a home visiting programme. The data was analysed using Reflexive Thematic Analysis. RESULTS: The analysis resulted in five pathways on two explanatory levels, affecting parents' health and parenting capacity and children's health and well-being, potentially damaging health and leading to health inequities. The first four pathways related to control at the personal explanatory level: Families facing instability and insecurity; Caring for children in crowded and poor housing conditions; Experiencing restricted access to resources; and Parenting with limited social support. The fifth pathway, Living in a segregated society, covered the collective experience of lack of control on community level. The Covid-19 pandemic was observed to negatively affect all pathways and thus potentially aggravate health inequities for this population. The pandemic has also limited the delivery of home visits to the families which creates further barriers in families' access to resources and increases isolation for parents with already limited social support. CONCLUSIONS: The diversity of pathways connected to health inequities presented in this study highlights the importance of considering this variety of influences when designing interventions for socioeconomically disadvantaged areas. The additional negative consequences of Covid-19 indicate the need for sustainable preventive early childhood interventions for families in such areas. The study also emphasizes the need for further research as well as policy action on possible long-term effects of changing behaviours during the Covid-19 period on child health and health equity. TRIAL REGISTRATION: The study was retrospectively registered (11 August 2016) in the ISRCTN registry ( ISRCTN11832097 ).

ABSTRACT

Social distancing measures have been a key component in government strategies to mitigate COVID-19 globally. Based on official documents, this study aimed to identify, compare and analyse public social distancing policy measures adopted in Denmark and Sweden regarding the coronavirus from 1 March 2020 until 1 October 2020. A key difference was the greater emphasis on laws and executive orders (sticks) in Denmark, which allowed the country to adopt many stricter policy measures than Sweden, which relied mostly on general guidelines and recommendations (sermons). The main policy adopters in Denmark were the government and the Danish Parliament, whereas the Public Health Agency issued most policies in Sweden, reflecting a difference in political governance and administrative structure in the two countries. During the study period, Sweden had noticeably higher rates of COVID-19 deaths and hospitalizations per 100,000 population than Denmark, yet it is difficult to determine the impact or relative effectiveness of sermons and sticks, particularly with regard to broader and longer-term health, economic and societal effects.

ABSTRACT

BACKGROUND: Sick-leave due to COVID-19 vary in length and might lead to re-current episodes. The aim was to investigate recurrent sick leave due to COVID-19 during the first wave. METHODS: This is a registry-based cohort study. The study comprises all people with sickness benefit due to COVID-19 in Sweden in March 1-August 31, 2020. Data from the Swedish Social Insurance Agency, the Swedish National Board of Health and Welfare, and Statistics Sweden were merged. RESULTS: Within the follow-up period of 4 months, 11,955 people were subject to sickness benefit due to COVID-19, whereof 242 people (2.0%) took recurrent sick leave due to COVID-19, and of those 136 (56.2%) remained on sick leave at the end of follow-up. People with recurrent sick leave were older, more often women, and more likely to have been on sick leave prior to the COVID-19 pandemic. CONCLUSION: A group of people presented with recurrent sick leave due to COVID-19. For half of them, the second sick leave lasted throughout the follow-up. People with recurrent sick leave differ in several aspects from those with shorter sick leave. To capture long-term sick-leave patterns due to COVID-19, a longer period of follow-up is needed.

ABSTRACT

A rapid stream of research confirms that the COVID-19 pandemic is a global threat to mental health and psychological well-being. It is therefore important to identify both hazardous and protective individual factors during the pandemic. The current research explored the relationships between self-reported affective responding, perceived personal consequences of the COVID-19 pandemic, and subjective well-being. An online survey (N = 471) conducted in Sweden between June and September, 2020, showed that higher levels of irritability, impulsivity, and the tendency to experience and express anger were generally associated with more severe personal consequences of the pandemic, particularly in areas related to family life, work/study, and finances. While more severe impacts of the pandemic in these areas of life were directly associated with lower subjective well-being, emotion regulation through cognitive reappraisal appeared to moderate the extent to which consequences of the pandemic in other areas of life (i.e., social, free-time and physical activities) translated into decreased well-being. This suggests that cognitive reappraisal may serve to protect against some of the debilitating effects of the COVID-19 pandemic on mental health. Overall, the results indicate that the perceived consequences of the pandemic are multifaceted and that future research should examine these consequences using a multidimensional approach.

ABSTRACT

BACKGROUND: The relationship between statin treatment and Coronavirus Disease 2019 (COVID-19) mortality has been discussed due to the pleiotropic effects of statins on coagulation and immune mechanisms. However, available observational studies are hampered by study design flaws, resulting in substantial heterogeneity and ambiguities. Here, we aim to determine the relationship between statin treatment and COVID-19 mortality. METHODS AND FINDINGS: This cohort study included all Stockholm residents aged 45 or older (N = 963,876), followed up from 1 March 2020 until 11 November 2020. The exposure was statin treatment initiated before the COVID-19-pandemic, defined as recorded statin dispensation in the Swedish Prescribed Drug Register between 1 March 2019 and 29 February 2020. COVID-19-specific mortality was ascertained from the Swedish Cause of Death Registry. Hazard ratios (HRs) were calculated using multivariable Cox regression models. We further performed a target trial emulation restricted to initiators of statins. In the cohort (51.6% female), 169,642 individuals (17.6%) were statin users. Statin users were older (71.0 versus 58.0 years), more likely to be male (53.3% versus 46.7%), more often diagnosed with comorbidities (for example, ischemic heart disease 23.3% versus 1.6%), more frequently on anticoagulant and antihypertensive treatments, less likely to have a university-level education (34.5% versus 45.4%), and more likely to have a low disposable income (20.6% versus 25.2%), but less likely to reside in crowded housing (6.1% versus 10.3%). A total of 2,545 individuals died from COVID-19 during follow-up, including 765 (0.5%) of the statin users and 1,780 (0.2%) of the nonusers. Statin treatment was associated with a lowered COVID-19 mortality (adjusted HR, 0.88; 95% CI, 0.79 to 0.97, P = 0.01), and this association did not vary appreciably across age groups, sexes, or COVID-19 risk groups. The confounder adjusted HR for statin treatment initiators was 0.78 (95% CI, 0.59 to 1.05, P = 0.10) in the emulated target trial. Limitations of this study include the observational design, reliance on dispensation data, and the inability to study specific drug regimens. CONCLUSIONS: Statin treatment had a modest negative association with COVID-19 mortality. While this finding needs confirmation from randomized clinical trials, it supports the continued use of statin treatment for medical prevention according to current recommendations also during the COVID-19 pandemic.

ABSTRACT

INTRODUCTION: Cancer patients are considered to have a higher risk of dying and developing severe Coronavirus Disease 2019 (COVID-19). To date, there are few studies including co-morbidities and sociodemographic factors when investigating the outcome of COVID-19 in a cohort of cancer patients. In this study, we analyzed cancer patients that have been hospitalized due to COVID-19 during the first wave of the pandemic in Sweden to investigate the impact of COVID-19 on mortality and morbidity. PATIENTS AND METHODS: We retrospectively collected data on all patients with cancer that were hospitalized due to COVID-19-related symptoms at Uppsala University Hospital and Karolinska University Hospital between 1 March and 31 August 2020. The primary endpoint was COVID-19-related death and the secondary endpoint was to describe COVID-19 severity, defined as symptom severity (grades 0-4) and length of stay (LOS) at the university hospitals. RESULTS: In total, 193 patients were included among which 31% died due to COVID-19 and 8% died of other causes. In a multivariable analysis, older age >70 (OR 3.6; 95% CI [1.8-7.3], p < 0.001) and male gender (OR 2.8 [1.4-5.8], p = 0.005) were factors associated with higher likelihood of COVID-19-related death. Several comorbidities ≥2 (OR 5.4 [2.0-14.3], p = 0.001) was independently associated with COVID-19 severity. Treatment with chemotherapy within 90 days prior to COVID-19 diagnosis were not associated with COVID-19-related death or severity. CONCLUSION: Factors associated with higher likelihood of COVID-19-related death were older age and male gender. More severe COVID-19 symptoms were seen in patients with multiple comorbidities. We did not see any associations between COVID-19-related death or severity and recent treatment including chemotherapy. In summary, this supports a thorough assessment regarding potential risks with COVID-19 infection in patients with cancer, with a combination of individual risk factors in addition to cancer treatments.

ABSTRACT

There is concern that immunotoxic environmental contaminants, particularly perfluoroalkyl substances (PFAS), may play a role in the clinical course of COVID-19 and epidemiologic studies are needed to answer if high-exposed populations are especially vulnerable in light of the ongoing pandemic. The objective was, therefore, to determine if exposure to highly PFAS-contaminated drinking water was associated with an increased incidence of COVID-19 in Ronneby, Sweden, during the first year of the pandemic. We conducted an ecological study determining the sex- and age-standardized incidence ratio (SIR) in the adult population relative to a neighboring reference town with similar demographic characteristics but with only background levels of exposure. In Sweden, COVID-19 is subject to mandatory reporting, and we retrieved aggregated data on all verified cases until 3 March 2021 from the Public Health Agency of Sweden. The SIR in Ronneby was estimated at 1.19 (95% CI: 1.12; 1.27). The results suggest a potential link between high PFAS exposure and susceptibility to COVID-19 that warrants further research to clarify causality.

ABSTRACT

BACKGROUND: Patients with obstructive lung diseases may be at risk of hospitalization and/or death due to COVID-19. AIM: To estimate the frequency of severe COVID-19, and COVID-19-related mortality in a well-defined large population of patients with asthma and chronic inflammatory lung disease (COPD). Further to assess the frequency of asthma and COPD as registered comorbidities at discharge from hospital, and in death certificates. METHODS: At the start of the pandemic, the Swedish National Airway Register (SNAR) included 271,404 patients with a physician diagnosis of asthma and/or COPD. In September 2020, after the first COVID-19 wave in Sweden, the database was linked with the National Patient Register (NPR), the Swedish Intensive Care Register and the Swedish Cause of Death Register, which all provide data about COVID-19 based on International Classification of Diseases (ICD-10) codes. Severe COVID-19 was defined as hospitalization and/or intensive care or death due to COVID-19. RESULTS: Among patients in SNAR, 0.5% with asthma, and 1.2% with COPD were identified with severe COVID-19. Among patients < 18 years with asthma, only 0.02% were severely infected. Of hospitalized adults, 14% with asthma and 29% with COPD died. Further, of patients in SNAR, 56% with asthma and 81% with COPD were also registered in the NPR, while on death certificates the agreement was lower (asthma 24% and COPD 71%). CONCLUSION: The frequency of severe COVID-19 in asthma and COPD was relative low. Mortality for those hospitalized was double as high in COPD compared to asthma. Comorbid asthma and COPD were not always identified among patients with severe COVID-19.

ABSTRACT

OBJECTIVES: Most COVID-19 related infections and deaths may occur in healthcare outside hospitals. Here we explored SARS-CoV-2 infections among healthcare workers (HCWs) in this setting. DESIGN: All healthcare providers in Stockholm, Sweden were asked to recruit HCWs at work for a study of past or present SARS-CoV-2 infections among HCWs. Study participants This study reports the results from 839 HCWs, mostly employees of primary care centers, sampled in June 2020. RESULTS: SARS-CoV-2 seropositivity was found among 12% (100/839) of HCWs, ranging from 0% to 29% between care units. Seropositivity decreased by age and was highest among HCWs <40 years of age. Within this age group there was 19% (23/120) seropositivity among women and 11% (15/138) among men (p<0.02). Current infection, as measured using PCR, was found in only 1% and the typical testing pattern of pre-symptomatic potential "superspreaders" found in only 2/839 subjects. CONCLUSIONS: Previous SARS-CoV-2 infections were common among younger HCWs in this setting. Pre-symptomatic infection was uncommon, in line with the strong variability in SARS-CoV-2 exposure between units. Prioritizing infection prevention and control including sufficient and adequate personal protective equipment, and vaccination for all HCWs are important to prevent nosocomial infections and infections as occupational injuries during an ongoing pandemic.

ABSTRACT

OBJECTIVES: To examine (i.e., contextualize and visualize) the consequences of a laissez-faire strategy characterized by blinkers to fulfill established pandemic goals. The aim is to shed light on the implementation of pandemic measures based on post hoc (after-the-fact) reactions and actions instead of pre hoc ones (in advance). STUDY DESIGN: This study is based on weekly updates of pandemic variables (i.e., cases, tests, percentage of positive tests, hospitalizations, Intensive Care Unit (ICU) admissions, deceased, and 7- and 14-day incidence) in Sweden from the start of the pandemic in March 2020 until March 2021. METHOD: This study reports the empirical findings based on Swedish pandemic variables during 52 consecutive weeks, related to the pandemic, all of which has been divided into three time periods to separate the 1st and 2nd waves of the pandemic, and considers them all together as one time period. RESULTS: The findings illustrate the implementation of pandemic measures and the subsequent consequences of a laissez-faire strategy characterized by blinkers. People become diseased and then deceased. This reveals strong associations between the assessed pandemic variables and its subsequent consequences on morbidity and mortality, based on post hoc reactions and actions. CONCLUSIONS: The implementation of a pandemic strategy should react and act pre hoc, and to take the safe with the unsafe. Governments and public health agencies should take into account the inevitable associations between pandemic variables. Intertwined pre hoc measures of prevention, enforcement, and monitoring should be implemented in society to avoid the implementation of a laissez-faire strategy based on post hoc reactions and actions.

ABSTRACT

OBJECTIVE: To assess the association of cardiometabolic risk factors with hospitalisation or death due to COVID-19 in the general population. DESIGN, SETTING AND PARTICIPANTS: Swedish population-based cohort including 29 955 participants. EXPOSURES: Cardiometabolic risk factors assessed between 2014 and 2018. MAIN OUTCOME MEASURES: Hospitalisation or death due to COVID-19, as registered in nationwide registers from 31 January 2020 through 12 September 2020. Associations of cardiometabolic risk factors with the outcome were assessed using logistic regression adjusted for age, sex, birthplace and education. RESULTS: Mean (SD) age was 61.2 (4.5) and 51.5% were women. 69 participants experienced hospitalisation or death due to COVID-19. Examples of statistically significant associations between baseline factors and subsequent hospitalisation or death due to COVID-19 included overweight (adjusted OR (aOR) vs normal weight 2.73 (95% CI 1.25 to 5.94)), obesity (aOR vs normal weight 4.09 (95% CI 1.82 to 9.18)), pre-diabetes (aOR vs normoglycaemia 2.56 (95% CI 1.44 to 4.55)), diabetes (aOR vs normoglycaemia 3.96 (95% CI 2.13 to 7.36)), sedentary time (aOR per hour/day increase 1.10 (95% CI 1.02 to 1.17)), grade 2 hypertension (aOR vs normotension 2.44 (95% CI 1.10 to 5.44)) and high density lipoprotein cholesterol (aOR per mmol/L increase 0.33 (95% CI 0.17 to 0.65)). Statistically significant associations were not observed for grade 1 hypertension (aOR vs normotension 1.03 (95% CI 0.55 to 1.96)), current smoking (aOR 0.56 (95% CI 0.24 to 1.30)), total cholesterol (aOR per mmol/L increase 0.90 (95% CI 0.71 to 1.13)), low density lipoprotein cholesterol (aOR per mmol/L increase 0.90 (95% CI 0.69 to 1.15)) and coronary artery calcium score (aOR per 10 units increase 1.00 (95% CI 0.99 to 1.01)). CONCLUSIONS: In a large population-based sample from the general population, several cardiometabolic risk factors were associated with hospitalisation or death due to COVID-19.

ABSTRACT

The Public Health Agency of Sweden has analyzed how many pregnant and postpartum women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been treated in intensive care units (ICU) in Sweden between 19 March and 20 April 2020 compared with non-pregnant women of similar age. Cases were identified in a special reporting module within the Swedish Intensive Care Registry (SIR). Fifty-three women aged 20-45 years with SARS-CoV-2 were reported in SIR, and 13 of these women were either pregnant or postpartum (<1 week). The results indicate that the risk of being admitted to ICU may be higher in pregnant and postpartum women with laboratory-confirmed SARS-CoV-2 in Sweden, compared with non-pregnant women of similar age.

ABSTRACT

OBJECTIVES: To evaluate the role of language proficiency and institutional awareness in explaining excess COVID-19 mortality among immigrants. DESIGN: Cohort study with follow-up between 12 March 2020 and 23 February 2021. SETTING: Swedish register-based study on all residents in Sweden. PARTICIPANTS: 3 963 356 Swedish residents in co-residential unions who were 30 years of age or older and alive on 12 March 2020 and living in Sweden in December 2019. OUTCOME MEASURES: Cox regression models were conducted to assess the association between different constellations of immigrant-native couples (proxy for language proficiency and institutional awareness) and COVID-19 mortality and all other causes of deaths (2019 and 2020). Models were adjusted for relevant confounders. RESULTS: Compared with Swedish-Swedish couples (1.18 deaths per thousand person-years), both immigrants partnered with another immigrant and a native showed excess mortality for COVID-19 (HR 1.43; 95% CI 1.29 to 1.58 and HR 1.24; 95% CI 1.10 to 1.40, respectively), which translates to 1.37 and 1.28 deaths per thousand person-years. Moreover, similar results are found for natives partnered with an immigrant (HR 1.15; 95% CI 1.02 to 1.29), which translates to 1.29 deaths per thousand person-years. Further analysis shows that immigrants from both high-income and low-income and middle-income countries (LMIC) experience excess mortality also when partnered with a Swede. However, having a Swedish-born partner is only partially protective against COVID-19 mortality among immigrants from LMIC origins. CONCLUSIONS: Language barriers and/or poor institutional awareness are not major drivers for the excess mortality from COVID-19 among immigrants. Rather, our study provides suggestive evidence that excess mortality among immigrants is explained by differential exposure to the virus.

ABSTRACT

Many studies, including self-controlled case series (SCCS) studies, are being undertaken to quantify the risks of complications following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19). One such SCCS study, based on all COVID-19 cases arising in Sweden over an 8-month period, has shown that SARS-CoV-2 infection increases the risks of AMI and ischemic stroke. Some features of SARS-CoV-2 infection and COVID-19, present in this study and likely in others, complicate the analysis and may introduce bias. In the present paper we describe these features, and explore the biases they may generate. Motivated by data-based simulations, we propose methods to reduce or remove these biases.

ABSTRACT

This study aimed to describe experiences of managing mental health and psychosocial activities during the first six months of the COVID-19 pandemic in Sweden. A national survey was answered by a non-probability sample of 340 involved in the psychosocial response. The psychosocial response operations met several challenges, mainly related to the diverse actors involved, lack of competence, and lack of preparations. Less than 20% of the participants had received specific training in the provision of psychosocial support during major incidents. The interventions used varied, and no large-scale interventions were used. The psychosocial response organizations were overwhelmed by the needs of health care staff and failed to meet the needs of patients and family members. An efficient and durable psychosocial response in a long-term crisis requires to be structured, planned and well-integrated into the overall pandemic response. All personnel involved need adequate and specific competence in evidence-based individual and large-scale interventions to provide psychosocial support in significant incidents. By increasing general awareness of mental wellbeing and psychosocial support amongst health professionals and their first-line managers, a more resilient health care system, both in everyday life and during major incidents and disasters, could be facilitated.

ABSTRACT

Against the COVID-19 pandemic, non-pharmaceutical interventions have been widely applied and vaccinations have taken off. The upcoming question is how the interplay between vaccinations and social measures will shape infections and hospitalizations. Hence, we extend the Susceptible-Exposed-Infectious-Removed (SEIR) model including these elements. We calibrate it to data of Luxembourg, Austria and Sweden until 15 December 2020. Sweden results having the highest fraction of undetected, Luxembourg of infected and all three being far from herd immunity in December. We quantify the level of social interaction, showing that a level around 1/3 of before the pandemic was still required in December to keep the effective reproduction number Refft below 1, for all three countries. Aiming to vaccinate the whole population within 1 year at constant rate would require on average 1,700 fully vaccinated people/day in Luxembourg, 24,000 in Austria and 28,000 in Sweden, and could lead to herd immunity only by mid summer. Herd immunity might not be reached in 2021 if too slow vaccines rollout speeds are employed. The model thus estimates which vaccination rates are too low to allow reaching herd immunity in 2021, depending on social interactions. Vaccination will considerably, but not immediately, help to curb the infection; thus limiting social interactions remains crucial for the months to come.

ABSTRACT

OBJECTIVE: High-quality longitudinal evidence exploring the mental health risk associated with low-quality employment trajectories is scarce. We therefore aimed to investigate the risk of being diagnosed with common mental disorders, substance use disorders, or suicide attempt according to low-quality employment trajectories. METHODS: A longitudinal register-study based on the working population of Sweden (N=2 743 764). Employment trajectories (2005-2009) characterized by employment quality and pattern (constancy, fluctuation, mobility) were created. Hazard ratios (HR) were estimated using Cox proportional hazards regression models for first incidence (2010-2017) diagnosis of common mental disorders, substance use disorders and suicide attempt as dependent on employment trajectories. RESULTS: We identified 21 employment trajectories, 10 of which were low quality (21%). With the exception of constant solo self-employment, there was an increased risk of common mental disorders (HR 1.07-1.62) and substance use disorders (HR 1.05-2.19) for all low-quality trajectories. Constant solo self-employment increased the risk for substance use disorders among women, while it reduced the risk of both disorders for men. Half of the low-quality trajectories were associated with a risk increase of suicide attempt (HR 1.08-1.76). CONCLUSIONS: Low-quality employment trajectories represent risk factors for mental disorders and suicide attempt in Sweden, and there might be differential effects according to sex - especially in terms of self-employment. Policies ensuring and maintaining high-quality employment characteristics over time are imperative. Similar prospective studies are needed, also in other contexts, which cover the effects of the Covid-19 pandemic as well as the mechanisms linking employment trajectories with mental health.
