Background: The study objective was to evaluate the impact of a population-level intervention (the IA Agreement) on the of one-year risk for long-term sickness absence spells (LSAS) among young and middle aged workers in Norway., Methods: Using an observational design, we conducted a quasi-experimental study to analyse registry data on individual LSAS for all employed individuals in 2000 (n = 298,690) and 2005 (n = 352,618), born in Norway between 1976 and 1967. The intervention of interest was the tripartite agreement for a more inclusive working life (the IA Agreement). We estimated difference in pre-post differences (DID) in LSAS between individuals working in IA companies with the intervention and companies without, in 2000 and 2005. We used logistic regression models and present odds ratios (DID OR) with accompanying 95% CI. We stratified analyses by sex, industry and company size., Results: We found no significant change in the overall risk of long-term sickness absence spells after implementing the intervention among young and middle aged workers. Stratified by sex, the intervention resulted in a slight decrease in LSAS risk among female workers (DID OR 0.93 (0.91-0.96)) while the intervention showed no impact among male workers (DID OR 1.01 (0.97-1.06)). We found that companies signing the IA Agreement were large (≥50 employees) and often within the manufacturing and health and social sectors. In large manufacturing companies, we found a reduction in LSAS, among workers both in companies with and without the intervention, resulting in no statistically significant impact of the IA intervention. In large health and social companies, we found an increase in LSAS among workers both in companies with and without the intervention. The increase was smaller among the workers in companies offering the IA intervention compared with workers in companies without, resulting in a positive impact of the IA intervention in the health and social industry. This impact was statistically significant only among female workers., Conclusions: The results indicate that the impact of the IA Agreement on the risk of long-term sickness absence spells varies considerably depending on sex and industry. These findings suggest that reducing LSAS may warrant industry-specific interventions.

Background: Studies show that migrant women are at greater risk of common mental disorders than the majority population, yet underrepresented in healthcare services. This study investigates the use of outpatient mental healthcare services over a five-year period among migrant and descendant women compared to majority women in Norway., Methods: Using linked national registry data, we selected all women resident in Norway between 2009 and 2013 (N = 1,834,822). We conducted generalised estimated equations with logistic regression to assess if the odds of using outpatient mental healthcare services differed for migrant and descendant women compared to majority women. We also conducted generalised estimated equations with negative binomial regression to calculate consultation incidence rate ratios for migrant and descendant women relative to majority women among those with a common mental disorder., Results: Both migrant and descendant women had lower odds (OR = 0.47 and OR = 0.60 respectively) of using outpatient mental healthcare services than majority women. Odds of using services increased with length of residency. We also found significant variation by country of origin. Among women with common mental disorders who had used services, migrants, but not descendants, had a lower consultation rate ratio than majority women. Analyses by region of origin revealed that this did not apply to women from EU European countries, North America and Australia and New Zealand., Conclusion: Women with migrant background are, overall, underrepresented in OPMH services. Findings indicate that migrant women may not only experience barriers to seeking and accessing care but also in maintaining access to care. This may especially be the case for newly arrived migrant women and women from non-Western countries. Treatment may not be culturally adapted for these groups. Closer investigation of the barriers migrant women experience after using OPMH services is required.

Background: Completing upper secondary education is associated with higher work participation and less health-related absence from work. Although these outcomes are closely interrelated, most studies focus on single outcomes, using cross-sectional designs or short follow-up periods. As such, there is limited knowledge of the long-term outcomes, and how paths for completers and non-completers unfold over time. In this paper, we use multi-state models for time-to-event data to assess the long-term effects of completing upper secondary education on employment, tertiary education, sick leave, and disability pension over twelve and a half years for young men., Methods: Baseline covariates and twelve and a half years of follow-up data on employment, tertiary education, sick leave and disability pension were obtained from national registries for all males born in Norway between 1971 and 1976 (n =184951). The effects of completing upper secondary education (by age 23) were analysed in a multi-state framework, adjusting for both individual and family level confounders. All analyses were done separately for general studies and vocational tracks., Results: Completers do better on a range of outcomes compared to non-completers, for both fields of upper secondary education, but effects of completion change over time. The largest changes are for tertiary education and work, with the probability of work increasing reciprocally to the probability of education. Vocational students are quicker to transfer to the labour market, but tend to have more unemployment, sick leave and disability, and the absolute effects of completion on these outcomes are largest for vocational tracks. However, the relative effects of completion are larger for general studies., Conclusion: Completing upper secondary education increases long-term work participation and lowers health-related absence for young men, but effects diminish over time. Studies that have used shorter follow-up periods could be overstating the negative effects of dropout on labour market participation. Multi-state models are well suited to analyse data on work, education and health-related absence, and can be useful in understanding the dynamic aspects of these outcomes.

Objective: This study aimed to quantify how much of the adult social gradient in sick leave can be attributed to the mediating role of physical workload while accounting for the role of childhood and adolescent social position and neuroticism., Methods: Our sample consisted of 2099 women and 1229 men from a Norwegian birth cohort study (born 1967-1976) who participated in the Nord-Trøndelag Health Study (2006-2008) (HUNT3). Data on sick leave (defined as >16 calendar days; 2006-2009) and social position during childhood, adolescence, and adulthood were obtained from national registers. Study outcome was time-to-first sick leave spell. Physical workload and neuroticism were self-reported in HUNT3. Mediating effects through physical workload were estimated using a method based on the additive hazards survival model., Results: A hypothetical change from highest to lowest group in adult social position was, for women, associated with 51.6 [95% confidence interval (95% CI) 24.7-78.5] additional spells per 100,000 person-days at risk, in a model adjusted for childhood and adolescent social position and neuroticism. The corresponding rate increase for men was 41.1 (95% CI 21.4-60.8). Of these additional spells, the proportion mediated through physical workload was 24% (95% CI 10-49) and 30% (95% CI 10-63) for women and men, respectively., Conclusions: The effect of adult social position on sick leave was partly mediated through physical workload, even while accounting for earlier life course factors. Our findings provide support that interventions aimed at reducing physical workload among those with lower adult social position could reduce sick leave risk.

Objectives: The aim of the study was to estimate associations between aerobic fitness among men at age 18-19 years and work absence due to musculoskeletal sickness 5-15 years later., Methods: All 321,975 men born between 1967 and 1976 in Norway were identified and followed up in several national registers. Men who completed an aerobic fitness test at military conscription during 1985-1995 (N=227,201) were followed from 2000 through 2003 with respect to a first musculoskeletal absence. Cox regression was conducted to estimate HRs between aerobic fitness (high, medium, poor) and musculoskeletal absence., Results: A total of 26,061 men had a musculoskeletal absence (absolute risk 0.115). Absence was associated with fitness level. Associations were confounded by other conscript characteristics (intellectual capacity, body mass index, musculoskeletal condition) and parental education level and were restricted to non-injury absence. With high fitness as reference, the adjusted non-injury HR estimates were 1.18 (95% CI 1.12 to 1.24) and 1.39 (1.31 to 1.47) for medium and poor fitness, respectively. Poor fitness men were more likely to achieve low educational attainment and employment in high-absence industries and enterprises. The impact of intellectual capacity and parental education level on absence was considerably larger than the effect from fitness. A subset analysis with fitness data of better quality yielded moderately stronger associations., Conclusions: Aerobic fitness among conscripts was moderately associated with non-injury musculoskeletal absence 5-15 years later. However, the overall impact of intellectual capacity and parental education appears to be greater than that of aerobic fitness.

Background: There are presently few international studies that examine adolescents' own experience of both triggering and the underlying reasons behind their suicide attempts., Aims: To present the rates, triggering factors, and underlying reasons for such behavior., Methods: The 23-year (1984-2006) surveillance study reported includes all general hospital-treated suicide attempters aged between 13 and 19 years (n = 254) living in the municipality of Bærum, a suburb on the outskirts of Oslo, Norway., Results: Suicide attempt rates for both sexes decreased during the period of study. The female suicide attempt rate was on average 3.5 times higher than the male rate. An average of 8.2% of the suicide attempters made a repeat attempt within the following year. Overall, the most commonly reported trigger was a relational conflict (50.2%), and the most commonly reported underlying reason was a dysfunctional family situation (43.6%), followed by mental health problems (22.8%). The main gender difference for both triggers and underlying reasons was that relational conflicts were reported significantly more often by girls than by boys as triggers (55.0% versus 32.7%), and dysfunctional family issues were reported significantly more often by girls than by boys (47.1% versus 30.8%) as underlying reasons for the attempt. Mental health problems were reported less frequently as an underlying reason by girls than boys (21.2% versus 28.8%)., Conclusions: A family-oriented intervention embracing the extended family system seems warranted in a majority of the cases in our study.
