Factors associated with general practitioners' contacts with sick-listed patients' employers: A Swedish nationwide questionnaire study.

Background: General practitioners' (GP) contacts with sick-listed patients' employers have been shown to be of importance for return to work. This study aimed to explore GPs' contacts with sick-listed patients' employers and factors associated with such contacts. Methods: In this cross-sectional study, 4228 GPs responded to a nationwide questionnaire about sickness certification (SC) practices. Outcomes of interest were participation in stakeholder meetings, having other contacts with employers, and satisfaction with employer contacts. Logistic regression models were used to investigate associations with factors related to the GP and the GP's workplace. Results: Among GPs, 34.8% participated in stakeholder meetings and 15.1% had other employer contacts; 39.4% had any or both of these contacts. Of GPs who had contacts with patients' employers, 65.8% were satisfied with the contacts. GPs regularly collaborating with rehabilitation coordinators had the strongest adjusted odds ratio (OR) for participating in stakeholder meetings, OR 2.72 (95% confidence interval (CI) 2.24-3.31), and having other contacts with employers, OR 3.85 (95% CI 2.85-5.21). Other factors positively associated with employer contacts were being a specialist, collaborating with other health professionals, finding employer contacts valuable, and having a joint SC routine/policy at the clinic. GPs who did not find SC problematic, had managerial support, or had enough resources for SC tasks were more likely to be satisfied with their employer contacts. Conclusions: Both physician characteristics and organizational factors had importance for GPs' contacts with sick-listed patients' employers. The findings imply that GPs' collaboration with patients' employers may be improved by interventions targeting both individual and organizational factors.

Emotional demands and all-cause and diagnosis-specific long-term sickness absence: a prospective cohort study in Sweden.

BACKGROUND: High emotional demands at work require sustained emotional effort and are associated with adverse health outcomes. We tested whether individuals in occupations with high emotional demands, compared with low demands, had a higher future risk of all-cause long-term sickness absence (LTSA). We further explored whether the risk of LTSA associated with high emotional demands differed by LTSA diagnoses. METHODS: We conducted a prospective, nationwide cohort study on the association between emotional demands and LTSA (>30 days) in the workforce in Sweden (n = 3 905 685) during a 7-year follow-up. Using Cox regression, we analyzed sex-stratified risks of all-cause and diagnosis-specific LTSA due to common mental disorders (CMD), musculoskeletal disorders (MSD) and all other diagnoses. Multivariable adjusted models included age, birth country, education, living area, family situation and physical work demands. RESULTS: Working in emotionally demanding occupations was associated with a higher risk of all-cause LTSA in women [hazard ratio (HR) = 1.92, 95% confidence interval (CI): 1.88-1.96] and men (HR = 1.23, 95% CI: 1.21-1.25). In women, the higher risk was similar for LTSA due to CMD, MSD and all other diagnoses (HR of 1.82, 1.92 and 1.93, respectively). In men, risk of LTSA due to CMD was pronounced (HR = 2.01, 95% CI: 1.92-2.11), whereas risk of LTSA due to MSD and all other diagnoses was only slightly elevated (HR of 1.13, both outcomes). CONCLUSIONS: Workers in occupations with high emotional demands had a higher risk of all-cause LTSA. In women, risk of all-cause and diagnosis-specific LTSA were similar. In men, the risk was more pronounced for LTSA due to CMD.

Trends in Associations Between Sickness Absence Before the Age of 65 and Being in Paid Work After the Age of 65: Prospective Study of Three Total Population Cohorts.

The increasing workforce participation at higher ages may impact social insurance systems, however, this has hardly been studied at all. We studied associations between sociodemographic factors and prior sickness absence and disability pension, with having paid work and sickness absence after age 65, and if such associations changed over time. We used longitudinal register data regarding three cohorts of all residents in Sweden who turned 65 in 2000, 2005, or 2010 (N = 50,000, 68,000, and 99,000, respectively). Although employment rates when aged 66-71 increased between the cohorts, associations of sociodemographic factors with paid work and sickness absence, when aged 66-71 did not. Both sickness absence and disability pension when aged 60-64 were negatively associated with working past 65. Sickness absence when aged 60-64 was positively associated and disability pension was negatively associated with sickness absence after 65. Possibilities to remain in paid work with different health conditions need to be strengthened to avoid inequalities when raising the retirement age.

Paid work increased from 2000 to 2010, sickness absence increased marginallyAssociations of sociodemographic factors with paid work did not change over timePrior sickness absence and disability pension correlate with paid work after age 65Sickness absence before age 65 correlates with sickness absence after 65Disability pension before age 65 correlates with less sickness absence after 65.

Trajectories of sickness absence and disability pension days among people with multiple sclerosis by type of occupation.

BACKGROUND: Multiple sclerosis (MS) can impact working life, sickness absence (SA) and disability pension (DP). Different types of occupations involve different demands, which may be associated with trajectories of SA/DP among people with MS (PwMS). OBJECTIVES: To explore, among PwMS and references, if SA/DP differ according to type of occupation. Furthermore, to examine how trajectories of SA/DP days are associated with type of occupation among PwMS. METHODS: A longitudinal nationwide Swedish register-based cohort study was conducted, including 6100 individuals with prevalent MS and 38,641 matched references from the population. Trajectories of SA/DP were identified with group-based trajectory modelling. Multinomial logistic regressions were estimated for associations between identified trajectories and occupations. RESULTS: Increase of SA/DP over time was observed in all occupational groups, in both PwMS and references, with higher levels of SA/DP among PwMS. The lowest levels of SA/DP were observed among managers. Three trajectory groups of SA/DP were identified: Persistently Low (55.2%), Moderate Increasing (31.9%) and High Increasing (12.8%). Managers and those working in Science & Technology, and Economics, Social & Cultural were more likely to belong to the Persistently Low group. CONCLUSION: Results suggest that type of occupation plays a role in the level and course of SA/DP.

Self-employment, sickness absence, and disability pension in multiple sclerosis.

OBJECTIVES: Early withdrawal from work is common among people with multiple sclerosis (PwMS). However, little is known about how this is influenced by the type of employment. The aims were to explore the distributions of self-employed and other types of employment (employed or no earnings from work) before and after MS diagnosis and its associations with sickness absence (SA) and disability pension (DP) among PwMS and matched references without MS. MATERIALS & METHOD: A 6-year longitudinal cohort study of 2779 individuals diagnosed with MS in 2008-2012 when aged 20-59 and of 13,863 matched individuals without MS from Sweden's population was conducted. Hazard ratios (HR) of >180 SA and/or DP days/year were compared by employment status among PwMS and references using Cox proportional hazard models with 95% confidence intervals (CI). RESULTS: Most had no SA or DP. Nevertheless, PwMS had higher SA and DP levels compared with references. PwMS had a higher likelihood to reach >180 days of SA (HR = 4.89, 95% CI = 4.43-5.40) or days of DP (HR = 6.31, 95% CI = 5.46-7.30), irrespective of the employment status. Self-employed references had less likelihood for >180 SA days than employed references. However, self-employed and employed PwMS had a similar likelihood for >180 SA days. Transitions of employees to self-employment were infrequent among PwMS (1.7%) and references (2.6%). CONCLUSIONS: PwMS transit to SA and DP to a higher extent than references. In contrast to individuals without MS, self-employed PwMS had similar SA levels to employed PwMS. Switching to self-employment was not a predominant choice for people recently diagnosed with MS.

Work stress and loss of years lived without chronic disease: an 18-year follow-up of 1.5 million employees in Denmark.

We aimed to examine the association between exposure to work stress and chronic disease incidence and loss of chronic disease-free life years in the Danish workforce. The study population included 1,592,491 employees, aged 30-59 in 2000 and without prevalent chronic diseases. We assessed work stress as the combination of job strain and effort-reward imbalance using job exposure matrices. We used Cox regressions to estimate risk of incident hospital-diagnoses or death of chronic diseases (i.e., type 2 diabetes, coronary heart disease, stroke, cancer, asthma, chronic obstructive pulmonary disease, heart failure, and dementia) during 18 years of follow-up and calculated corresponding chronic disease-free life expectancy from age 30 to age 75. Individuals working in occupations with high prevalence of work stress had a higher risk of incident chronic disease compared to those in occupations with low prevalence of work stress (women: HR 1.04 (95% CI 1.02-1.05), men: HR 1.12 (95% CI 1.11-1.14)). The corresponding loss in chronic disease-free life expectancy was 0.25 (95% CI - 0.10 to 0.60) and 0.84 (95% CI 0.56-1.11) years in women and men, respectively. Additional adjustment for health behaviours attenuated these associations among men. We conclude that men working in high-stress occupations have a small loss of years lived without chronic disease compared to men working in low-stress occupations. This finding appeared to be partially attributable to harmful health behaviours. In women, high work stress indicated a very small and statistically non-significant loss of years lived without chronic disease.

Sickness absence and disability pension after carpal tunnel syndrome diagnosis: A register-based study of patients and matched references in Sweden.

Aims: The aim of this study was to examine sickness absence and disability pension (SA/DP) during working lifespan among individuals diagnosed with carpal tunnel syndrome (CTS) and their matched references, accounting for sociodemographic factors. Methods: We used a register cohort of 78,040 individuals aged 19-60 years when diagnosed with CTS in secondary health care (hospitals and outpatient specialist health care) and their 390,199 matched references from the general population in 2001-2010. Sociodemographic factors and SA/DP net days during a three-year follow-up were included. Negative binomial regression was used. Results: For those not on DP at inclusion, the average number of SA/DP days per person-year was 58 days (95% confidence interval (CI) 56-60 days) among individuals with CTS and 20 days (95% CI 19-21 days) among the matched references. Among both groups, these numbers increased with age and were higher among women than among men. The rate ratio (RR) of SA/DP days was threefold higher among people with CTS than among the matched references (adjusted RR=3.00, 95% CI 2.91-3.10) Moreover, compared to the matched references, the RR for SA/DP was higher among men with CTS (RR=3.86, 95% CI 3.61-4.13) than among women with CTS (RR=2.69, 95% CI 2.59-2.78). The association between CTS and the number of SA/DP days was smaller among older age groups. Sociodemographic factors were similarly associated with SA/DP among people with and without CTS. Conclusions: Numbers of SA/DP days were higher among people with CTS than their matched references in all age groups, particularly among individuals in their early work careers, highlighting public-health relevance of the findings.

Sickness absence and disability pension three years before and seven years after first childbirth: A Swedish population-based cohort study.

AIMS: There is a widely held belief, in Sweden and internationally, that women with children are more likely to be on sickness absence (SA) than their nulliparous counterparts. However, empirical findings in the field are limited and inconsistent. We aimed to explore initially nulliparous women's patterns of SA and disability pension (DP) three years before and seven years after 2009, by later parity. METHODS: We conducted a longitudinal cohort study of nulliparous women in Sweden on 31 December 2009 (N=426,918). We compared crude and standardized numbers of SA/DP net days in the three years before (Y-3 to Y-1) and the seven years (Y+1 to Y+7) after the date of the first birth in 2010 or 2 July 2010 in the following three groups: (1) women with no childbirth during the seven-year follow-up and an additional nine months (i.e. 7.8 years), (2) women with a first childbirth in 2010 and no additional childbirth during the next 7.8 years, and (3) women with their first childbirth in 2010 and minimum one more during the next 7.8 years. RESULTS: Women remaining nulliparous had consistently more standardized mean SA/DP days than women giving birth. Compared with women with one birth, women with several births had similar mean numbers of standardized SA/DP days during Y-3 and Y-2, more during Y+1 to Y+3 and fewer during Y+4 to Y+7. CONCLUSIONS: In contrast to the widely held societal belief, we found that in all years women who gave birth had fewer SA/DP days than those remaining nulliparous.

Trajectories of sickness absence and disability pension days among 189,321 white-collar workers in the trade and retail industry; a 7-year longitudinal Swedish cohort study.

OBJECTIVE: 1) identify different trajectories of annual mean number of sickness absence (SA) and disability pension (DP) days among privately employed white-collar workers in the trade and retail industries and 2) investigate if sociodemographic and work-related characteristics were associated with trajectory membership. METHODS: A longitudinal population-based cohort register study of all white-collar workers in the trade and retail industry in 2012 in Sweden (N = 189,321), with SA and DP data for 2010-2016. Group-based trajectory analysis was used to identify groups of individuals who followed similar trajectories of SA/DP days. Multinomial logistic regression was used to determine associations between sociodemographic and work-related factors and trajectory membership. RESULTS: We identified four trajectories of SA/DP days. Most individuals (73%) belonged to the trajectory with 0 days during all seven years, followed by a trajectory of few days each year (24%). Very small minorities belonged to a trajectory with increasing SA/DP days (1%) or to constantly high SA/DP (2%). Men had a lower risk of belonging to any of the three trajectories with SA/DP than women (OR Low SA/DP 0.42, 95% CI 0.41-0.44; Increasing SA/DP 0.34, 0.30-0.38; High SA/DP 0.33, 0.29-0.37). Individuals in occupations with low job control had a higher risk of belonging to the trajectory High SA/DP (OR low demands/low control 1.51; 95% CI 1.25-1.83; medium demands/low control 1.47, 1.21-1.78; high demands/low control 1.35, 1.13-1.61). CONCLUSION: Most white-collar belonged to trajectories with no or low SA/DP. Level of job control was more strongly associated with trajectory memberships than level of job demands.

Clustering of disability pension and socioeconomic disadvantage in Sweden: a geospatial analysis.

BACKGROUND: To characterize geospatial patterning of disadvantage in Sweden, we examined whether municipal-level indicators of socioeconomic disadvantage and disability pension (DP) rate were clustered, whether the different geospatial clusters were overlapping and whether the findings were similar among women and men. METHODS: Administrative national data from all 290 Swedish municipalities were used to determine the prevalence of DP and socioeconomic disadvantage [poverty, long-term unemployment, income inequality (GINI Index) and income inequality between women and men]. Geospatial cold spots (clusters of municipalities with a DP/socioeconomic disadvantage prevalence lower than the nationwide prevalence) and hot spots (clusters of municipalities with a DP/socioeconomic disadvantage higher than the nationwide prevalence) were identified, and whether a hot spot was overlapping with another hot spot and a cold spot overlapping with another cold spot were analysed using the Getis-Ord Gi statistics. RESULTS: Among women and men, cold spots of DP were most consistently located in the Stockholm area. Hot spots of DP were found in the mid-south Sweden, characterized by mid-sized urban centres in rural territories. High DP rate and socioeconomic disadvantage were overlapping, except for income inequality. Clusters of gender income inequality and women's high DP rate were observed in mid-south Sweden. CONCLUSION: DP and socioeconomic disadvantage are not randomly distributed in Sweden. Geospatial analyses revealed clusters of municipalities with high risk of both DP and socioeconomic disadvantage in certain areas and low risk in other areas. Further research is needed to identify preventive actions to decrease regional inequalities in work capacity.

Clustering of social disadvantage with attention-deficit/hyperactivity disorder in young adults: A register-based study in Sweden.

The clustering of social disadvantage with attention-deficit/hyperactivity disorder (ADHD) in young adulthood is not well understood. We examined the clustering of ADHD with low educational attainment and unemployment in young adulthood; whether such clustering is stronger when unemployment is prolonged; and whether further clustering of disability pensioning, low education and unemployment occurs among those with ADHD. Data were obtained from Swedish health, demographic and social security registers from which 8,990 individuals with recorded ADHD diagnoses at the age of 10-35 and their 44,387 matched referents without mental disorders. Social disadvantage was measured using data on educational attainment, unemployment and disability pension from the diagnosis year or age 19 if diagnosed at younger age. Clustering was examined by comparing observed and expected occurrence (O/E ratio) of all possible combinations of ADHD, low education and unemployment, and, among those with ADHD, additional combinations with new-onset disability pension. The likelihood of having neither ADHD, low education nor unemployment was increased (O/E ratio = 1.20, 95% confidence interval 1.19-1.20 at baseline; 1.18, 1.17-1.18 at follow-up), as well as having all three characteristics (O/E ratio = 3.99, 3.89-4.10 at baseline; 5.68, 5.47-5.89 at follow-up). This clustering was stronger among women than men and when unemployment was prolonged. The results suggest that low education and unemployment appear to cluster remarkably with ADHD among young adults, more so among women and when unemployment is prolonged.

Healthcare use, sickness absence, and disability pension among colorectal cancer survivors and population references in Sweden.

BACKGROUND: Colorectal cancer (CRC) has negative long-term impacts on survivors' health and work capacity. We aimed to investigate specialized healthcare use and sickness absence and disability pension among CRC survivors and matched references. MATERIAL AND METHODS: In this longitudinal register-based cohort study, 6679 patients with a first primary CRC in 2008-2011 (when aged 18-62) and 26,716 CRC-free matched references were followed from 2 years before up to 5 years after diagnosis date. Mean numbers of hospital days and outpatient visits were illustrated for survivors and references for the 7-year period. Crude and adjusted mean numbers of sickness absence/disability pension net days were calculated for post-diagnosis Years 3 and 5. RESULTS: Survivors' healthcare use was higher compared to their references throughout the 7 years around CRC diagnosis and was mostly due to CRC, secondary neoplasms, and digestive disorders. In Year 5, survivors had 1.94 mean outpatient visits and 2.13 mean inpatient days (compared to 1.00 and 0.82 for references, respectively). Survivors' adjusted mean sickness absence/disability pension days amounted to 85 d in Year 3 and 77 in Year 5 (compared to 57 and 54 d in the references). Higher mean number of future days was found among women, lower-educated, foreign-born, with previous comorbidities or previous mental disorders. Those with many sickness absence days in 2 years pre-diagnosis had the highest number of future sickness absence/disability pension days. CONCLUSIONS: Post-diagnostic healthcare use remained high among CRC survivors, mostly due to cancer (CRC and other neoplasms) and digestive diagnoses. Their sickness absence and disability pension decreased gradually over the period but remained higher than among references. Pre-morbid characteristics may be used in early work-related clinical planning for the survivors.

Factors of decisive importance for being in work or not during two years after breast cancer surgery: content analysis of 462 women's open answers.

BACKGROUND: Paid work is one of the most important aspects in life among working-aged women diagnosed with breast cancer. Despite several attempts, no previous study provides a comprehensive overview from the women's perspective about factors of importance for being able to work or not. Therefore, the aim of this study was to gain knowledge about factors that women themselves state are of decisive importance for being able to work or not during the first two years after breast cancer surgery. METHODS: Data was collected in a two-year follow-up questionnaire within the frame of a prospective cohort study of working-aged women who had undergone breast cancer surgery. 749 were included in the questionnaire study and of the 616 (82%) responding women, 462 (75%) wrote statements on an open-ended question about factors of decisive importance for being able to work or not work during the past two years. The statements were analyzed with content analysis. RESULTS: Five categories of factors of importance for being able to  work or not were identified, each covering several sub-categories: Health and wellbeing, Contacts and encounters, Flexibility and adjustment possibilities, Socioeconomic consequences from working/not working, and Own motivation and characteristics. A wide variety of factors were mentioned by the women and the findings give a multifaceted picture of many single but interrelated factors of decisive importance for being able to work/not work. The importance of flexibility in the return-to-work process was stressed, as well as the importance of supportive encounters from, e.g., colleagues, managers, as well as relatives. CONCLUSIONS: The results give a comprehensive overview over a variety of different types of factors for being able to return to/remain in work or to not work after breast cancer surgery, adding new knowledge about e.g. the importance of colleagues, and the women's own preferences or characteristics. These are factors that different stakeholders, both from healthcare but also from the work place and the insurance office, need to be aware of and collaborate around to support women with breast cancer during the period of treatment, rehabilitation and return to work.

Sickness absence among privately employed white-collar workers: A total population study in Sweden.

Background: Knowledge about sickness absence (SA) and disability pension (DP) among privately employed white-collar workers is very limited. Aims: This study aimed to explore SA and DP among privately employed white-collar women and men using different measures of SA to investigate differences by branch of industry, and to analyse the association between sociodemographic factors and SA. Methods: This was a population-based study of all 1,283,516 (47% women) privately employed white-collar workers in Sweden in 2012, using register data linked at the individual level. Several different measures of SA and DP were used. Logistic regression was used to investigate associations of sociodemographic factors with SA. Results: More women than men had SA (10.9% women vs. 4.5% men) and DP (1.8% women vs. 0.6% men). While women had a higher risk of SA than men and had more SA days per employed person, they did not have more SA days per person with SA than men. The risk of SA was higher for women (odds ratio (OR)=2.54 (95% confidence interval (CI) 2.51-2.58)), older individuals (OR age 18-24 years=0.58 (95% CI 0.56-0.60); age 55-64 years OR=1.43 (95% CI 1.40-1.46) compared to age 45-54 years), living in medium-sized towns (OR=1.05 (95% CI 1.03-1.06)) or small towns/rural areas (OR=1.13 (95% CI 1.11-1.15)), with shorter education than college/university (OR compulsory only=1.64 (95% CI 1.59-1.69); OR high school=1.38 (95% CI 1.36-1.40)), born outside the EU25 (OR=1.23 (95% CI 1.20-1.27)) and singles with children at home (OR=1.33 (95% CI 1.30-1.36)). Conclusions: SA and DP among privately employed white-collar workers were lower than in the general population. SA prevalence, length and risk varied by branch of industry, sex and other sociodemographic factors, however, depending on the SA measure used.

Oncologists' experiences of and prerequisites for sickness certification tasks: A nationwide questionnaire study.

Oncologists frequently have sickness certification (SC) consultations, however, little is known about their experiences of such tasks. OBJECTIVE: To investigate oncologists' experiences of organisational prerequisites for SC tasks, and if lack of resources was related to experiencing SC as problematic. METHOD: Questionnaire data from 342 oncologists in Sweden were used for descriptive statistics and to calculate odds ratios (OR) with 95% confidence intervals (CI). RESULTS: The majority (92.2%) had SC consultations weekly; 17.8% of the oncologists experienced such consultations as problematic weekly. About a third appreciated the national guidelines for SC (34.5%) and had joint routines/policies regarding SC at their clinic (29.7%). Experiencing SC consultations as problematic was associated with stating not having enough resources for such work (OR 3.47; 95% CI 1.92-6.25). Lack of resources was associated with: experiencing lack of competence in insurance medicine (3.34; 1.92-5.82), conflicts with patients regarding SC (4.22; 1.96-9.07), finding it problematic to manage the two roles as medical expert and as the patient's treating physician (3.31; 2.04-5.34), or to assess work capacity (2.28; 1.46-3.56). CONCLUSION: Although oncologists often had SC tasks, most did not experience them as problematic weekly. However, lack of resources for SC tasks was associated with experiencing SC as problematic.

Sickness absence and disability pension among injured working-aged pedestrians - a population-based Swedish register study.

BACKGROUND: The knowledge is scarce about sickness absence (SA) and disability pension (DP) among pedestrians injured in a traffic-related accident, including falls. Thus, the aim was to explore the frequencies of types of accidents and injuries and their association with SA and DP among working-aged individuals. METHODS: A nationwide register-based study, including all individuals aged 16-64 and living in Sweden, who in 2010 had in- or specialized outpatient healthcare after a new traffic-related accident as a pedestrian. Information on age, sex, sociodemographics, SA, DP, type of accident, injury type, and injured body region was used. Frequencies of pedestrians with no SA or DP, with ongoing SA or full-time DP already at the time of the accident, and with a new SA spell >14 days in connection to the accident were analyzed. Crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for new SA were estimated by logistic regression. RESULTS: In total, 5576 pedestrians received healthcare due to a traffic-related accident (of which 75% were falls, with half of the falls related to snow and ice). At the time of the accident, 7.5% were already on SA and 10.8% on full-time DP, while 20% started a new SA spell. The most common types of injuries were fractures (45%) and external injuries (30%). The body region most frequently injured was the lower leg, ankle, foot, and other (in total 26%). Older individuals had a higher OR for new SA compared with younger (OR 1.91; 95% CI 1.44-2.53, for ages: 45-54 vs. 25-34). The injury type with the highest OR for new SA, compared with the reference group external injuries, was fractures (9.58; 7.39-12.43). The injured body region with the highest OR for new SA, compared with the reference group head, face, and neck, was lower leg, ankle, foot, and other (4.52; 2.78-7.36). CONCLUSIONS: In this explorative nationwide study of the working-aged pedestrians injured in traffic-related accidents including falls, one fifth started a new SA spell >14 days. Fractures, internal injuries, collisions with motor vehicle, and falls related to snow and ice had the strongest associations with new SA.

Associations of sickness absence and disability pension due to mental and somatic diagnoses when aged 60-64 with paid work after the standard retirement age; a prospective population-based cohort study in Sweden.

BACKGROUND: The proportion of people working beyond age 65 is increasing. We aimed to explore whether sickness absence (SA) and disability pension (DP) due to mental, somatic, or both diagnoses when aged 60-64 were associated with being in paid work when aged 66-71. METHODS: This prospective population-based cohort study included all 98,551 individuals who in 2010 turned 65 years, lived in Sweden, and were in paid work at some point when aged 60-64. Data from three nationwide registers were used with 2010 as baseline, with SA or/and DP as the exposure variables (2005-2009) and paid work as the outcome variable (2011-2016). Logistic regression was conducted to calculate odds ratios (OR) with 95% confidence intervals (CI) for the association between exposures and outcome, controlling for sociodemographic factors. The analyses were also stratified by sex. RESULTS: Nearly half were in paid work during follow-up. Those with SA due to mental diagnoses had lower likelihood of being in paid work among both sexes (women OR: 0.76; 95% CI: 0.69-0.84; men 0.74; 0.65-0.84), while this association was smaller for SA due to somatic diagnoses (women 0.87; 0.84-0.91; men 0.92; 0.89-0.96). SA due to both mental and somatic diagnoses was associated with a lower likelihood of paid work for men (0.77; 0.65-0.91), but not women (0.98; 0.88-1.09). Regardless of diagnosis group and sex, DP had the strongest association with not being in paid work (women mental DP 0.39; 0.34-0.45; women somatic DP 0.38; 0.35-0.41; women mental and somatic DP 0.28; 0.15-0.56; men mental DP 0.36; 0.29-0.43; men somatic DP 0.35; 0.32-0.38; men mental and somatic DP 0.22; 0.10-0.51). Combined SA and/or DP demonstrated ORs in-between the diagnosis groups of SA and DP alone (e.g., mental SA and/or DP women and men combined 0.61; 0.57-0.65). CONCLUSIONS: SA and DP were negatively associated with being in paid work after the standard retirement age of 65. The association was especially strong for DP, irrespective of diagnosis group. Moreover, compared to somatic diagnoses, SA due to mental diagnoses had a stronger association with not being in paid work. More knowledge is needed on how mental SA impedes extending working life.

Sickness absence and disability pension among women with breast cancer: a population-based cohort study from Sweden.

BACKGROUND: Women's return to work after diagnosis of breast cancer (BC) is becoming more prevalent. However, register-based national investigation on sickness absence (SA) and disability pension (DP) in BC women is lacking. The aim of the study was to explore SA and DP before and after a first BC diagnosis and the possibility to predict new cancer-related SA by using disease-related and sociodemographic factors. METHODS: A longitudinal register study of the 3536 women in Sweden aged 19-64 with a first BC diagnosis in 2010 was conducted by linkage of five nationwide registers. Particularly, detailed information on SA and DP was obtained from the National Social Insurance Agency. Descriptive statistics on SA and DP 2 years before through 3 years after the BC diagnosis were performed. The risk of having a new SA spell due to BC or BC-related diagnoses was modeled using logistic regression. RESULTS: The proportion of women with SA increased during the year following the BC diagnosis date and declined over the next 2 years to proportions before diagnosis. At the time of BC diagnosis, half of the women began a new SA spell > 14 days with cancer, cancer-related, or mental diagnosis. Disease-related and sociodemographic factors including occupational sector, living area, age, cancer stage, educational level, and number of previous SA days showed statistical significance (p < 0.05) in predicting a new SA around BC diagnosis. By using these factors, it was possible to correctly predict 67% of the new SA spell. CONCLUSIONS: SA among women with BC was elevated mainly in the first year after diagnosis. New SA following BC diagnosis can accurately be predicted.

Predicting the duration of sickness absence due to knee osteoarthritis: a prognostic model developed in a population-based cohort in Sweden.

BACKGROUND: Predicting the duration of sickness absence (SA) among sickness absent patients is a task many sickness certifying physicians as well as social insurance officers struggle with. Our aim was to develop a prediction model for prognosticating the duration of SA due to knee osteoarthritis. METHODS: A population-based prospective study of SA spells was conducted using comprehensive microdata linked from five Swedish nationwide registers. All 12,098 new SA spells > 14 days due to knee osteoarthritis in 1/1 2010 through 30/6 2012 were included for individuals 18-64 years. The data was split into a development dataset (70 %, nspells =8468) and a validation data set (nspells =3690) for internal validation. Piecewise-constant hazards regression was performed to prognosticate the duration of SA (overall duration and duration > 90, >180, or > 365 days). Possible predictors were selected based on the log-likelihood loss when excluding them from the model. RESULTS: Of all SA spells, 53 % were > 90 days and 3 % >365 days. Factors included in the final model were age, sex, geographical region, extent of sickness absence, previous sickness absence, history of specialized outpatient healthcare and/or inpatient healthcare, employment status, and educational level. The model was well calibrated. Overall, discrimination was poor (c = 0.53, 95 % confidence interval (CI) 0.52-0.54). For predicting SA > 90 days, discrimination as measured by AUC was 0.63 (95 % CI 0.61-0.65), for > 180 days, 0.69 (95 % CI 0.65-0.71), and for SA > 365 days, AUC was 0.75 (95 % CI 0.72-0.78). CONCLUSION: It was possible to predict patients at risk of long-term SA (> 180 days) with acceptable precision. However, the prediction of duration of SA spells due to knee osteoarthritis has room for improvement.

Contribution of income and job strain to the association between education and cardiovascular disease in 1.6 million Danish employees.

AIMS: We examined the extent to which associations between education and cardiovascular disease (CVD) morbidity and mortality are attributable to income and work stress. METHODS AND RESULTS: We included all employed Danish residents aged 30-59 years in 2000. Cardiovascular disease morbidity analyses included 1 638 270 individuals, free of cardiometabolic disease (CVD or diabetes). Mortality analyses included 41 944 individuals with cardiometabolic disease. We assessed education and income annually from population registers and work stress, defined as job strain, with a job-exposure matrix. Outcomes were ascertained until 2014 from health registers and risk was estimated using Cox regression. During 10 957 399 (men) and 10 776 516 person-years (women), we identified 51 585 and 24 075 incident CVD cases, respectively. For men with low education, risk of CVD was 1.62 [95% confidence interval (CI) 1.58-1.66] before and 1.46 (95% CI 1.42-1.50) after adjustment for income and job strain (25% reduction). In women, estimates were 1.66 (95% CI 1.61-1.72) and 1.53 (95% CI 1.47-1.58) (21% reduction). Of individuals with cardiometabolic disease, 1736 men (362 234 person-years) and 341 women (179 402 person-years) died from CVD. Education predicted CVD mortality in both sexes. Estimates were reduced with 54% (men) and 33% (women) after adjustment for income and job strain. CONCLUSION: Low education predicted incident CVD in initially healthy individuals and CVD mortality in individuals with prevalent cardiometabolic disease. In men with cardiometabolic disease, income and job strain explained half of the higher CVD mortality in the low education group. In healthy men and in women regardless of cardiometabolic disease, these factors explained 21-33% of the higher CVD morbidity and mortality.
