It is not well known how the timing of entry into paid employment and physical work exposures contribute to different health outcomes in young employees. Thus, we determined the associations of age at entry into paid employment and physical work exposures with general and mental health in young employees and determined whether associations differ by behavior-related risk factors. Data were collected via online and mailed surveys in autumn 2017 from employees of the City of Helsinki aged 18-39 years (n = 5897; 4630 women and 1267 men, response rate 51.5%). Surveys comprised measures of age at entry into paid employment, seven working conditions, behavior-related risk factors and health outcomes (self-rated health [SRH] and common mental disorders [CMD] as generic indicators of physical and mental health). Logistic regression analysis was used. After full adjustment, age at entry was not associated with the health outcomes; however, in additional analyses, younger age at first employment was associated with smoking and obesity (OR 3.00, 95% CI 2.34-3.85 and 1.67, 95% CI 1.32-2.11 for those started working at age of ≤18 years, respectively). Of the working conditions, sitting and standing were positively associated with poor SRH and CMD and uncomfortable working postures with CMD. Working conditions were broadly similarly associated with health outcomes among those with and without behavior-related risk factors. Although we found little support for modification by behavior-related risk factors, overweight, obesity and smoking were associated with poor SRH and binge drinking and smoking with CMD. Additionally, moderate and high levels of leisure-time physical activity were inversely associated with poor SRH. In conclusion, early entry into paid employment appears not to associate to immediate poorer health in young employees, although it was associated with smoking and obesity even after full adjustment. Exposure to physically heavy work and uncomfortable working postures may increase the risk of adverse health outcomes.

Background: Prior analyses of class differences in health trajectories among employees have often omitted women and transitions to retirement. We examined social class trajectories in physical functioning among Finnish female employees from midlife to retirement age, and whether transitions to retirement modified these trajectories., Methods: Data were derived from mail surveys at Phases 1-3 (2000-2012) among employees of the City of Helsinki, Finland, aged 40-60 at baseline (n = 8960, 80% women, response rates 69-83%). We included respondents to any of the Phases 1-3 aged 40-72 (n = 6976). We distinguished higher and lower social classes, and employment statuses, i.e. employed, mandatorily retired and disability-retired. Short Form 36 physical component summary was used to measure physical functioning. Mixed-effect growth curve models were used to assess the association of social class and employment status with functioning over age., Results: For employed women, physical functioning deteriorated faster in the lower than in the higher class, with class trajectories widening in ages 40-65. After mandatory retirement, functioning deteriorated in both classes, whereas after disability retirement, functioning improved. Across employment statuses, functioning converged at older ages, and the disability-retired caught up with the better functioning of the employed and mandatorily retired. Employment status modified the trajectories, as among the continuously employed and mandatorily retired women functioning deteriorated, but among the disability-retired, trajectories improved and reached a similar level with employed and mandatorily retired women. Social class inequalities remained in all employment status groups., Conclusions: Overall, our results suggest evidence for the cumulative disadvantage model, with accumulating work exposures among lower classes potentially contributing to their trajectories of ill health.

Background: Early exit from paid employment is a notable public health and societal challenge. Previous research has largely focused on the relationships among variables instead of the relationships among individuals with different work participation history. Person-oriented methods enable to identify latent groups of individuals who are likely to follow similar development in their work participation over time. We thus aimed to identify work participation trajectories during early and midlife careers and their social determinants using large nationally representative data comprising over 1 million initially employed individuals and a 10-year follow-up for their work participation. A further aim was to determine the cumulative incidence of sickness absence due to key diagnostic groups, mental disorders and musculoskeletal diseases within the trajectories., Methods: Young (25-38 years at baseline, n = 495,663) and midlife (39-52 years at baseline, n = 603,085) Finnish people, all working in 2004, were followed up through 2013, with registers of the Social Insurance Institution, and the Statistics Finland. The registers provided data for work participation and its determinants, as well as for computing the cumulative incidence of sickness absence. Latent class growth analysis was used to identify trajectories., Results: Three distinctive trajectories were identified: temporary exit, permanent exit, and continuously employed people. As compared to the other trajectories, those belonging to the permanent exit trajectory were more likely men, manual workers and had a lower income. The cumulative incidence of sickness absence due to mental disorders was highest in the permanent exit trajectory group. For musculoskeletal diseases, the cumulative incidence of sickness absence increased in the permanent exit trajectory mainly in the older age groups., Conclusion: Distinct group-based trajectories of early work exit can be identified in a representative cohort of initially employed people. Focusing on the determinants of premature exit and early intervention to tackle increasing sickness absence may promote work participation particularly in the most vulnerable groups.

Background: Changes in health functioning over different retirement transitions are poorly understood. This study aimed to examine associations between transition into statutory, disability and part-time retirement, and changes in health functioning., Methods: Survey data were collected among ageing employees of the City of Helsinki, Finland, at three phases: (i) (2000-02), (ii) (2007) and (iii) (2012). Physical and mental health functioning were measured using the Short-Form 36 questionnaire at each phase. Retirees between phases 1 and 3 were identified from the national registers of the Finnish Centre for Pensions: full-time statutory retirement (n = 1464), part-time retirement (n = 404), and disability retirement (n = 462). Generalized estimating equations were used to examine the associations., Results: Disability retirees had poorer pre- and post-retirement health functioning compared to statutory and part-time retirees. Statutory and part-time retirement were associated with no or only small changes in physical health functioning during retirement transition (β 0.1, 95% CI -0.3 to 0.5 and -1.0, -1.8 to -0.1, respectively), whereas a clear decline in functioning was observed among disability retirees (-4.3, -5.4 to -3.2). Mental health functioning improved during the retirement transition among statutory and part-time retirees (1.9, 1.4-2.4 and 2.0, 1.0-3.0, respectively), whereas no change was observed for disability retirees., Conclusions: Transition to disability retirement led to a decrease in physical health functioning, and statutory retirement to a slight improvement in mental health functioning. Evidence on changes in physical and mental health functioning during retirement transition process may provide useful information for interventions to promote healthy ageing.

Objectives: Mental disorders are a key cause of sickness absence (SA) and challenge prolonging working careers. Thus, evidence on the development of SA trends is needed. In this study, educational differences in long SAs due to mental disorders were examined in two age groups among employees of the City of Helsinki from 2004 to 2013., Methods: All permanently and temporarily employed staff aged 18-34 and 35-49 were included in the analyses (n=~27800 per year). SA spells of ≥14 days due to mental disorders were examined annually. Education was classified to higher and lower levels. Joinpoint regression was used to identify major turning points in SA trends., Results: Joinpoint regression models showed that lower educated groups had more long SAs spells due to mental disorders than those groups with higher education. SA trends decreased during the study period in all studied age and educational groups. Lower educated age groups had similar SA trends. Younger employees with higher education had the fewest SAs., Conclusions: A clear educational gradient was found in long SAs due to mental disorders during the study period. SA trends decreased from 2004 to 2013.

Objectives: Alcohol drinking is associated with ill health but less is known about its contribution to overall functioning. We aimed to examine whether alcohol drinking predicts self-reported mental and physical functioning 5-7 years later., Design: A prospective cohort study., Setting: Helsinki, Finland., Participants: 40-year-old to 60-year-old employees of the City of Helsinki (5301 women and 1230 men) who participated in a postal survey in 2000-2002 and a follow-up survey in 2007., Primary and Secondary Outcome Measures: Mental and physical functioning measured by the Short Form 36 Health Survey., Results: Alcohol drinking was differently associated with mental and physical functioning. Heavy average drinking, binge drinking and problem drinking were all associated with subsequent poor mental functioning except for heavy average drinking among men, whereas only problem drinking was associated with poor physical functioning. Also, non-drinking was associated with poor physical functioning. Problem drinking was the drinking habit showing most widespread and strongest associations with health functioning. The associations between problem drinking and poor mental functioning and with poor physical functioning among women remained after adjusting for baseline mental functioning, sociodemographic factors, working conditions and other health behaviours., Conclusions: Alcohol drinking is associated especially with poor mental functioning. Problem drinking was the drinking habit strongest associated with poor health functioning. The results call for early recognition and prevention of alcohol problems in order to improve health functioning among employees., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Objective: Socioeconomic differences in sickness absence (SA) are well established among older employees but poorly understood among the young. Our aim was to examine 12-year trends in educational differences in SA among young female and male employees, and to assess the magnitude of the differences., Design: We examined annual SA spells. The data were obtained from the employer's registers and linked to Statistics Finland's register data on completed education and qualifications. Education was classified into four hierarchical groups. Joinpoint regression models were used to identify turning points in SA trends. The magnitude of the relative educational differences was estimated in accordance with the relative index of inequality for 2002, 2008 and 2013., Setting: Employees of the City of Helsinki, Finland, in 2002-2013., Participants: The analyses covered female and male employees aged 25-34 years: employees aged 35-54 years were used as a reference group., Outcome: SA spells., Results: An educational gradient emerged among younger and older women and men. SA spells increased in the early 2000s, and downward turning points were located in 2007-2010 in all educational groups among women and in most groups among men. The magnitude of the differences remained broadly stable among younger women from 2002 to 2013, and decreased slightly among older women and more strongly among younger and older men. The educational differences were greater among men than women in the early 2000s, but similar among both at the end of the study period., Conclusions: The changes in SA spells may reflect the economic downturn started in 2008 and resulting job insecurity. Early preventive measures aimed at reducing educational differences in SA should be focused at an early stage on those with low levels of education in particular., (Published by the BMJ Publishing Group Limited.

Objectives: The aim this study was to examine the effect of changes in physical and psychosocial working conditions on physical health functioning among ageing municipal employees., Methods: Follow-up survey data were collected from midlife employees of the City of Helsinki, Finland, at three time points: wave 1 (2000-2002), wave 2 (2007), and wave 3 (2012). Changes in physical and psychosocial working conditions were assessed between waves 1 and 2. Physical health functioning was measured by the physical component summary (PCS) of the Short-Form 36 questionnaire at each of the three waves. In total, 2784 respondents (83% women) who remained employed over the follow-up were available for the analyses. Linear mixed-effect models were used to assess the associations and adjust for key covariates (age, gender, obesity, chronic diseases, and health behaviors)., Results: Repeated and increased exposure to adverse physical working conditions was associated with greater decline in physical health functioning over time. In contrast, decrease in exposures reduced the decline. Of the psychosocial working conditions, changes in job demands had no effects on physical health functioning. However, decreased job control was associated with greater decline and repeated high or increased job control reduced the decline in physical health functioning over time., Conclusions: Adverse changes in physical working conditions and job control were associated with greater decline in physical health functioning over time, whereas favorable changes in these exposures reduced the decline. Preventing deterioration and promoting improvement of working conditions are likely to help maintain better physical health functioning among ageing employees.

Background: A low socioeconomic position (SEP) is consistently associated with ill health, sickness absence (SA) and permanent disability, but studies among young employees are lacking. We examined the interrelationships between education, occupational class and income as determinants of SA among 25-34-year-old employees. We also examined, whether the association between SEP and SA varied over time in 2002-2007 and 2008-2013., Methods: The analyses covered young, 25-34-year-old women and men employed by the City of Helsinki over the time periods 2002-2007 and 2008-2013. Four-level education and occupational class classifications were used, as well as income quartiles. The outcome measure was the number of annual SA days., Results: Education had the strongest and most consistent independent association with SA among women and men in both periods under study. Occupational class had weaker independent and less consistent association with SA. Income had an independent association with SA, which strengthened over time among the men. The interrelationships between the SEP indicators and SA were partly explained by prior or mediated through subsequent SEP indicators. Socioeconomic differences followed only partially a gradient for occupational class and also for income among men., Conclusions: Preventive measures to reduce the risk of SA should be considered, especially among young employees with a basic or lower-secondary education.

Background: Obesity is associated with an increased risk of work disability, but studies concerning weight change are few. We examined the associations of weight change with subsequent sickness absence., Methods: Weight status data of 4164 (83% women) employees of the City of Helsinki were gathered from the Helsinki Health Study baseline survey in 2000-2002 and follow-up survey in 2007. Data were linked prospectively with the employer's sickness absence registers. Employees were categorized according to their baseline Body Mass Index (normal weight, overweight, obese) as well as weight change (weight gainer, weight loser, weight maintainer) between the two surveys. The association of weight change with sickness absence spells was analysed with Poisson regression., Results: Among women, those who maintained normal weight had the lowest risk for sickness absence. Weight loss, weight gain and stable obesity increased the risk for sickness absence spells of all lengths. Adjustments for covariates attenuated the association only slightly. Among men, the achieved results were mostly not statistically significant., Conclusions: Preventing obesity and weight gain is important for employee well-being and work ability. Early support measures in occupational health care could benefit obese employees and those with weight gain to maintain work ability. The association between weight loss and sickness absence should be corroborated in further studies., (© The Author 2014.

Objectives: Young adults entering employment are a key group in extending work careers, but there is a lack of research on trends in work ability among young employees. Prolonged sickness absence (SA) constitutes a risk for permanent work disability. We examined 12-year trends in SA spells among young female and male municipal employees., Methods: The data were obtained from the employers' registers in the City of Helsinki, Finland. The data included employees aged 18-24, 25-29, 30-34, and 35-54 from 2002 to 2013 (the average number for each year was 31,600). Self-certified (1-3 days) and medically certified intermediate (4-14 days) and long (15+ days) SAs were examined. Joinpoint regression models were used to identify major changes in SA trends., Results: Younger employees had more short SAs but fewer long SAs than older employees. During the study period, SAs of almost any length first increased and later decreased among both genders, except for young men. The turning points for short SA were in 2007-2011 among younger and older employees. In intermediate and long SAs the respective turning points were in 2008-2009 and 2005-2009. Women had more SAs in all categories., Conclusions: Age is related to the length of absences. Given the relatively low chronic morbidity among younger employees, it is likely that reasons other than ill health account for increased SA. More evidence on factors behind the changing trends is needed in order to reduce SA and extend the working careers of young people.

Income inequalities widened considerably from 1987 to 2007 in Finland. We compared the association between household income and health problems across three periods and in several different ways of modelling the dependence. Our aim was to find out whether the change in the distribution of income might have led to wider income-related inequalities in health problems. The data represent an 11-per-cent random sample of the Finnish population, and we restricted the analysed sample to those between 18 and 67 years of age and not in receipt of any pension in each of the three six-year periods examined (n between 280,106 and 291,198). The health outcome was sickness-allowance days compensated. Household-equivalent taxable income was applied with two different scale transformations: firstly, as real income adjusted for price level and secondly, as rank position on the income distribution. We used negative binomial regression models, with and without zero inflation, as well as decomposition analysis. We found that sickness-allowance days decreased with increasing income, while differences in the shape and magnitude of the association were found between the scales and the periods. During the study period the association strengthened considerably at both the lowest fifth and the top fifth of the rank scale, while the observed per-unit effect of real income changed less. Decomposition analysis suggested that slightly less than half of the observed increase in concentration of health problems at lower end of the rank scale could be accounted for by the change in real income distribution. The results indicate that widening differences in household consumption potential may have contributed to an intensified impact of household income on inequalities in health problems. Explaining the change only in terms of consumption potential, however, was problematic, and changes in the interdependence of labour-market advantage and health problems are likely to contribute as well., (Copyright © 2013 Elsevier Ltd.

Objective: The main aims of this longitudinal study were to (i) examine associations between changes in economic difficulties and health functioning among middle-aged employees and (ii) assess whether the associations remained after considering conventional domains of socioeconomic position. The associations were tested in two European welfare state occupational cohorts to strengthen the evidence base and improve generalizability., Methods: Data came from two cohorts: the Finnish Helsinki Health Study (baseline 2000-2002, follow-up 2007, N = 6328) and the British Whitehall II Study (baseline 1997-1999, follow-up 2003-2004, N = 4350). Responses to the survey item "finding it hard to afford adequate food and clothes and pay bills" repeated at baseline and follow-up were used to examine persistent, increasing, and decreasing economic difficulties. Poor physical and mental health functioning were denoted as being in the lowest quartile of the Short Form 36 physical and mental component summary. Logistic regression analyses were adjusted for sex, age, childhood economic difficulties, household income at baseline and follow-up, employment status at follow-up, and baseline health functioning., Results: We observed strong sex- and age-adjusted associations between increasing [odds ratio (OR) range 1.69-2.96] and persistent (OR range 2.54-3.21) economic difficulties and poorer physical and mental health functioning in both British and Finnish occupational cohorts. These associations remained after full adjustments. Those reporting decreasing difficulties over follow-up also had poorer functioning (OR range 1.30-1.61) compared to those who did not have difficulties at baseline, possibly reflecting residual effects of economic difficulties at baseline., Conclusion: Changes in economic difficulties are associated with poorer physical and mental health functioning independent of income, employment status, and baseline health functioning.

Our aim was to find out whether the associations between health and both individual and household economic position reflected a causal effect on health of household affluence and consumption potential. We attempted to separate this effect from health-selection effects, in other words the potential effect of health on economic position, and from various effects related to occupational position and prestige that might correlate with the economic indicators. We made a distinction between individual labour-market advantage and household economic resources in order to reflect these theoretical definitions. Our aim was to test and compare two hypotheses: 1) low household economic resources lead to an increase in health problems later on, and 2) health problems are disadvantageous on the labour market, and consequently decrease the level of economic resources. We used prospective register data obtained from the databases of Statistics Finland and constituting an 11-per-cent random sample of the Finnish population in 1993-2006. Health problems were measured in terms of sickness allowance paid by the Finnish Social Insurance Institution, household economic resources in terms of household-equivalent disposable income and taxable wealth, and labour-market advantage in terms of individual taxable income and months of unemployment. We used structural equation models (n = 211,639) to examine the hypothesised causal pathways. Low household economic resources predicted future health problems, and health problems predicted future deterioration in labour-market advantage. The effect of economic resources on health problems was somewhat stronger. These results suggest that accumulated exposure to low economic resources leads to increasing health problems, and that this causal mechanism is a more significant source of persistent health inequalities than health problems that bring about a permanent decrease in economic resources., (Copyright © 2012 Elsevier Ltd.

Background: Social determinants of sleep may prove to be as important as health status. In this study we examined the extent to which persistent and changing economic difficulties are associated with sleep problems in two prospective occupational cohorts., Methods: We used data from Finnish (baseline 2000-2002; follow-up 2007; n=6328) and British (baseline 1997-1999; follow-up 2003-2004; n=5002) public sector employees. Economic difficulties, sleep problems, and a variety of covariates were assessed at baseline and follow-up., Results: Prevalence of frequent sleep problems at follow-up was 27% and 20% among women and men in the Finnish cohort, and 34% and 27% in the British cohort, respectively. Odds for sleep problems were higher among those with persistent economic difficulties (frequent economic difficulties at baseline and follow-up) compared to those with no difficulties. This association remained after multiple adjustments, including parental and current socioeconomic position, in the Finnish (OR 1.72, 95% CI 1.35-2.18) cohort. Increases in economic difficulties were similarly associated with sleep problems in the Finnish and the British cohort., Conclusion: Evidence from two occupational cohorts suggests strong associations between economic difficulty and poor sleep. Awareness of this association will help health care professionals identify and prevent sleep problems., (Copyright © 2012 Elsevier B.V. All rights reserved.)

Background: Childhood and current economic difficulties are associated with physical health. However, evidence concerning the factors underlying these associations is sparse. This study examines the contribution of a range of social and behavioural factors to associations between economic difficulties and physical functioning., Methods: We used comparable data on middle-aged white-collar employees from the Finnish Helsinki Health Study cohort (n = 3843) and the British Whitehall II Study cohort (n = 3052). Our health outcome was physical functioning measured by the SF-36 Physical Component Summary. Relative indices of inequality (RII), calculated using logistic regression analysis, were used to examine associations between economic difficulties and physical functioning, and the contribution of further socio-economic circumstances, health behaviours, living arrangements and work-family conflicts to these associations., Results: In age-adjusted models, childhood (RII = 1.76-3.06) and current (RII = 1.79-3.03) economic difficulties were associated with poor physical functioning in both cohorts. Further adjusting for work-family conflicts attenuated the associations of current economic difficulties with physical functioning in both cohorts, and also those of childhood economic difficulties in the Helsinki cohort. Adjustments for other socio-economic circumstances also caused some attenuation, while health behaviours and living arrangements had small or negligible effects., Conclusions: Conflicts between work and family contribute to the associations of economic difficulties with physical functioning among employees from Finland and Britain. This suggests that supporting people to cope with economic difficulties, and efforts to improve the balance between paid work and family may help employees maintain good physical functioning.

This study aimed to examine how physical working conditions, psychosocial working conditions and work-family conflicts are associated with sleep complaints, and whether health behaviours explain these associations. We used pooled postal questionnaire surveys collected in 2001-2002 among 40-60-year-old employees of the City of Helsinki (n = 5819, response rate 66%). Participants were classified as having sleep complaints if they reported sleep complaints at least once a week on average (24% of women and 20% of men). Independent variables included environmental work exposures, physical workload, computer work, Karasek's job strain and work-family conflicts. Age, marital status, occupational class, work arrangements, health behaviours and obesity were adjusted for. Most working conditions were associated strongly with sleep complaints after adjustment for age only. After adjustment for work-family conflicts, the associations somewhat attenuated. Work-family conflicts were also associated strongly with women's [odds ratio (OR) 5.90; confidence interval (CI) 4.16-8.38] and men's sleep (OR 2.56; CI 1.34-4.87). The associations remained robust even after controlling for unhealthy behaviours, obesity, health status, depression and medications. Physically strenuous working conditions, psychosocial job strain and work-family conflicts may increase sleep complaints. Efforts to support employees to cope with psychosocial stress and reach a better balance between paid work and family life might reduce sleep complaints. Sleep complaints need to be taken into account in worksite health promotion and occupational health care in order to reduce the burden of poor sleep.

This study aims to examine social class differences in smoking, heavy drinking, unhealthy food habits, physical inactivity and obesity, and work-related psychosocial factors as explanations for these differences. This is done by comparing employee cohorts from Britain, Finland and Japan. Social class differences in health behaviours are found in the two western European countries, but not in Japan. The studied psychosocial factors related to work, work-family interface and social relationships did not explain the found class differences in health behaviours.

Objective: While health inequalities among employees are well documented, their variation and determinants among employee subpopulations are poorly understood. We examined variations in occupational class inequalities in health within four employment sectors and the contribution of working conditions to these inequalities., Methods: Cross-sectional data from the Helsinki Health Study in 2000-2002 were used. Each year, employees of the City of Helsinki, aged 40-60 years, received a mailed questionnaire (n = 8,960, 80% women, overall response rate for 3 years 67%). The outcome was physical health functioning measured by the overall physical component summary of SF-36. The socioeconomic indicator was occupational social class. Employment sectors studied were health care, education, social welfare and administration (n = 6,557). Physical and mental workload, and job demands and job control were explanatory factors. Inequality indices from logistic regression analysis were calculated., Results: Occupational class inequalities in physical health functioning were slightly larger in education (1.47) than in the other sectors (1.43-1.40). Physical workload explained 95% of inequalities in social welfare and 32-36% in the other sectors. Job control also partly explained health inequalities. However, adjusting for mental workload and job demands resulted in larger health inequalities., Conclusion: Inequalities in physical health functioning were found within each employment sector, with minor variation in their magnitude. Physical workload was the main explanation for these inequalities, but its contribution varied between the sectors. In contrast, considering psychosocial working conditions led to wider inequalities. Improving physical working conditions among the lower occupational classes would help reduce health inequalities within different employment sectors.

Background: To further increase our understanding of socio-economic health inequalities, we need studies considering multiple socio-economic circumstances and comparing different cultural contexts. This study compared the associations of past and present socio-economic circumstances with physical functioning between employees from Finland and Britain., Methods: Cross-sectional survey data from the Helsinki Health Study (n = 5866) and the Whitehall II Study (n = 3052) were used. Participants were white-collar public sector employees aged 45-60 years. Physical functioning was measured with the SF-36 physical component summary. The socio-economic indicators were parental and own education, childhood and current economic difficulties, occupational class, income, housing tenure., Results: Childhood and current economic difficulties were independently associated with physical functioning in both cohorts, although in London women childhood difficulties did not reach statistical significance. Own education was independently associated with physical functioning in Helsinki. Occupational class showed associations with physical functioning in both cohorts. These were mainly attenuated by education and income, but in London women there was a strong independent association. The association of income with physical functioning was attenuated by education (Helsinki) and occupational class (London). Parental education and housing tenure showed no consistent associations., Conclusions: Past and present economic difficulties were independently associated with physical functioning. The conventional socio-economic indicators showed less consistent associations which were partly mediated through other indicators and modified by the national context. The associations that varied according to the indicators and between the cohorts highlight the importance of considering the multiplicity of socio-economic circumstances and comparing different cultural contexts in further studies.

Objectives: It was hypothesised that job decision latitude may alleviate the detrimental health effect of physical workload. The objective was to test whether job decision latitude modifies the effect of physically demanding work on poor physical functioning, and whether the effects of physically demanding work and job decision latitude are dependent on occupational social class., Methods: Data were derived from the Helsinki Health Study baseline questionnaire survey. The participants were employees of the City of Helsinki, Finland, aged 40-60 years. Functioning was measured by Short Form 36 physical component summary. Logistic regression models were used to analyse the data., Results: The hypothesised modification of the effect of physical demands at work on physical functioning by job decision latitude could not be demonstrated. The expected interaction effect was observed only for the semi-professional class, and interaction of physical demands, decision latitude and occupational social class was not statistically significant. Furthermore, the effects of physically demanding work as well as low decision latitude were of similar magnitude in all the occupational social classes., Conclusions: The results suggest that for the majority of employees the effect of physical workload on physical functioning is independent of job decision latitude or occupational social class in general. Control over work conditions is unlikely to reduce difficulties to cope with physical demands, when the actual physical tasks are not changed.

Background: Common mental disorders do not always show as consistent socioeconomic gradients as severe mental disorders and physical health. This inconsistency may be due to the multitude of socioeconomic measures used and the populations and national contexts studied. We examine the associations between various socioeconomic circumstances and common mental disorders among middle-aged Finnish and British public sector employees., Methods: We used survey data from the Finnish Helsinki Health Study (n = 6028) and the British Whitehall II Study (n = 3116). Common mental disorders were measured by GHQ-12. The socioeconomic indicators were parental education, childhood economic difficulties, own education, occupational class, household income, housing tenure and current economic difficulties. Logistic regression analysis was the main statistical method used., Results: Childhood and current economic difficulties were strongly associated with common mental disorders among men and women in both the Helsinki and the London cohort. The more conventional indicators of socioeconomic circumstances showed weak or inconsistent associations. Differences between the two cohorts and two genders were small., Conclusions: Our findings emphasize the importance of past and present economic circumstances to common mental disorders across different countries and genders. Overall, our results suggest that among employee populations, the socioeconomic patterning of common mental disorders may differ from that of other domains of health.

Background: The aim of the study was to investigate (1) how much of the association between health and social class is accounted by psychosocial working conditions, and (2) whether health is related to working conditions after controlling for social class., Methods: The data derive from the surveys of the Helsinki health study, collected in 2000, 2001, and 2002 from 40-60 year old employees working for the City of Helsinki (n=8970, response rate 67%). The study measured occupation based social class and Karasek's demand-control model. The health outcomes were self rated health as less than good and limiting longstanding illness. Age adjusted prevalence percentages and fitted logistic regression models were calculated., Results: The individual effects of social class and psychosocial working conditions on self rated health and limiting longstanding illness were strong among both men and women. The relation between social class and both health outcomes considerably attenuated when job control was controlled for, but was reinforced when controlling for job demands. Controlling for both job control and job demands attenuated the relation between social class and self rated health and limiting longstanding illness among women, however, was reinforced among men., Conclusions: A substantial part of the relation between social class and health could be attributed to job control, however, job demands reinforced the relation. Although the effect of social class is mediated by psychosocial working conditions, both social class and working conditions were related to health after mutual adjustments.

Objective: To examine the association between relative body weight and health status and the potential modifying effects of socioeconomic position and working conditions on this association., Research Methods and Procedures: The data were derived from three identical cross-sectional surveys conducted in 2000, 2001, and 2002. Respondents to postal surveys were middle-aged employees of the City of Helsinki (7148 women and 1799 men, response rate 67%). BMI was based on self-reported weight and height. Health status was measured by the Short-Form 36 subscales and component summaries., Results: Body weight was inversely associated with physical health, but in mental health, differences between BMI categories were small and inconsistent. In women, physical health deteriorated monotonically with increasing BMI, whereas in men, poor physical health was found among the obese only. Socioeconomic position did not modify the association between BMI and health. In women, the association between body weight and physical health became stronger with decreasing job control and increasing physical work load, whereas in men, a similar modifying effect was found for high job demands., Discussion: Body weight was associated with physical health only. Lower levels of relative weight in women than in men may be associated with poor physical health. High body weight combined with adverse working conditions may impose a double burden on physical health.

Background: Studies comparing socioeconomic inequalities in health using several health indicators are scarce. Therefore, this study aims to compare the shape and magnitude of occupational class inequalities across key domains of health, i.e. the subjective, functional and medical domains. Additionally, we examine whether physical or mental workload will affect these inequalities, and whether these effects are specific to particular health indicators., Methods: Cross-sectional survey data from the Helsinki Health Study in 2000 and 2001 were used. Each year employees of the City of Helsinki, reaching 40, 45, 50, 55 and 60 years received a mailed questionnaire. 6243 employees responded (80% women, response rate 68%). The socioeconomic indicator was occupational social class. Nine health indicators were included: self-rated health, pain or ache, GHQ-12 mental well-being, limiting long-standing illness, SF-36 physical and mental health functioning, Rose angina symptoms, circulatory diseases and mental problems. Prevalence percentages, odds ratios and inequality indices from logistic regression analysis were calculated., Results: Occupational class inequalities were found for self-rated health, pain or ache, limiting long-standing illness, physical health functioning, angina symptoms, and circulatory diseases. Physical or mental workload did not account for these inequalities. Inequalities were non-existent or slightly reversed for GHQ-12 mental well-being, SF-36 mental health functioning and mental problems., Conclusion: Expected occupational class inequalities in health among both women and men were found for global and physical health but not for mental health. The observed inequalities could not be attributed to physical or mental workload.

The main aim of this study is to compare the patterning of health by family status and employment status among women in Finland and Sweden and to explore whether the patterning of health by family status is influenced by employment status and income. An additional aim was to identify which combinations of family status and employment status are especially disadvantageous for women's health . The data derived from comparable interview surveys carried out in 1994/1995. The analyses were restricted to ages 25-49; 2282 women in Finland and 2685 in Sweden. Firstly, age-adjusted prevalence percentages were presented by family status and employment status. Secondly, the patterning of health by family status and employment status, and the influence of adjusting for income, were studied by logistic regression analysis. The main results showed that women living in couples with children had the best health in both countries. Additional analyses showed that in Finland particularly poor health can be found among women who are simultaneously non-partnered and non-employed, whereas in Sweden poor health can be found among all non-employed groups of women. Income did not explain the poor health among the non-partnered and non-employed. This study confirmed that health is patterned by family status and employment status both among Finnish and Swedish women. It was found that non-employed women without a partner are likely to have poor health. In order to reduce inequalities in health among women, more efforts should be put on promoting health among these groups.

Pain is a strong predictor of reduced work ability and well-being, but there is little information on the prevalence of and socio-economic differences in acute, chronic and disabling chronic pain among employees. A questionnaire survey conducted in 2000-2002 among employees aged 40, 45, 50, 55 and 60 of the City of Helsinki (N=8970, response rate 67%) included socio-demographic and socio-economic factors and measures of current pain, pain duration and pain-related disability. Pain was acute when lasting a maximum of 3 months and chronic when persisting for more than 3 months. Disabling chronic pain was determined using the disability subscale of Von Korff's Chronic Pain Grade questionnaire. Acute pain was reported by 15% of women, chronic pain by 29% and disabling chronic pain by 7%. The corresponding figures for men were 12, 24 and 5%. Chronic and disabling chronic pain were more common in older age groups among both genders. Among women, those with secondary or basic education were more likely to report chronic or disabling chronic pain than those with higher education, and semi-professionals, routine non-manual employees and manual workers were more likely to report disabling chronic pain than managers. Among men, separated/divorced or widowed men were more likely to report acute pain than married men, and manual workers were more likely to report chronic pain than managers. Chronic pain was relatively common in this population, and those with older age, lower education and occupational class appear to be at excess risk for chronic pain, especially for disabling chronic pain.

Aims: The Nordic countries have relatively equal employment participation between men and women, but some differences between countries exist in labour market participation. The aim was to examine the association between employment status and health among women and men in Denmark, Finland, Norway, and Sweden, and analyse whether this association is modified by marital status and parental status., Methods: The data come from nationally representative cross-sectional surveys carried out in Denmark (n = 2,209), Finland (n = 4,604), Norway (n = 1,844) and Sweden (n = 5,360) in 1994-95. Women and men aged 25-49 were included. Employment status was categorized into full-time employed, part-time employed, unemployed, and housewives among women and into employed and unemployed among men. Health was measured by perceived health and limiting longstanding illness. Logistic regression analysis was used, adjusting for age and education. Marital status and parental status were analysed as modifying factors., Results: The non-employed were more likely to report perceived health as below good and limiting longstanding illness than the employed among both women and men. The association between employment status and perceived health remained unchanged when marital status and parental status were adjusted for among all men and Finnish women, but the association was slightly strengthened among Danish and Swedish women, with the housewives becoming more likely to report ill health than employed women. The association between employment status and limiting longstanding illness was slightly strengthened among women, and slightly weakened among Norwegian men when marital and parental status were adjusted for., Conclusions: Non-employment was associated with poorer health in all countries, although there are differences in the employment patterns between the countries. Among women marital status and parental status showed a modest or no influence on the association between employment status and health. Among men there was no such influence.

Background: Although there have been a number of studies on the effects of multiple roles on health and how a combination of work and family roles may be either advantageous (role enhancement) or disadvantageous (role strain) for health, there has been relatively little investigation on the psychosocial content of such roles. Work-to-family conflict and family-to-work conflict could arise from inability to combine multiple roles and result in stress and ill health. The question of whether both types of conflict mediate between the association of multiple roles with health has not been analysed before. This paper sets out to investigate whether: (1) work-to-family conflict or family-to-work conflict contributes towards explaining the association of multiple roles with mental health; (2) the effect of work-to-family conflict and family-to-work conflict on mental health varies by gender; (3) the effect of work-to-family and family-to-work conflict on mental health vary between countries with different welfare state arrangements and social norms., Methods: Cross-sectional data of economically active male and female public sector employees aged 35-60 in London (UK), Helsinki (Finland), and the West Coast of Japan. Linear regression models (separate for each gender and cohort) of SF-36 mental component scores were analysed with role combinations, family-to-work and work-to-family conflict as explanatory variables., Results: Single fathers in all three cohorts and of single mothers in the Helsinki cohort had poor mental health, and this was partly explained by their higher levels family-to-work conflict. Both types of conflict affect the mental health of men and women independently of each other. Japanese women had the greatest conflict and poorest mental health while Helsinki women had the lowest conflict and best mental health., Conclusion: Both work-to-family and family-to-work conflict affect the mental health of men and women in three different countries. Work and family roles and the balance between the two may be important for the mental health of men and women in industrialized societies. Any analysis of the effect of multiple roles on health needs to take into account the psychosocial content of such roles.

Study Objective: Many previous studies on socioeconomic inequalities in health have neglected the causal interdependencies between different socioeconomic indicators. This study examines the pathways between three socioeconomic determinants of ill health., Design, Setting, and Participants: Cross sectional survey data from the Helsinki health study in 2000 and 2001 were used. Each year employees of the City of Helsinki, reaching 40, 45, 50, 55, and 60 years received a mailed questionnaire. Altogether 6243 employees responded (80% women, response rate 68%). Socioeconomic indicators were education, occupational class, and household income. Health indicators were limiting longstanding illness and self rated health. Inequality indices were calculated based on logistic regression analysis., Main Results: Each socioeconomic indicator showed a clear gradient with health. Among women half of inequalities in limiting longstanding illness by education were mediated through occupational class and household income. Inequalities by occupational class were largely explained by education. A small part of inequalities for income were explained by education and occupational class. For self rated health the pathways were broadly similar. Among men most of the inequalities in limiting longstanding illness by education were mediated through occupational class and income. Part of occupational class inequalities were explained by education. Two thirds of inequalities by income were explained by education and occupational class., Conclusions: Parts of the effects of each socioeconomic indicator on health are either explained by or mediated through other socioeconomic indicators. Analyses of the predictive power of socioeconomic indicators on health run the risk of being fruitless, if interrelations between various indicators are neglected.

Previous studies have shown a positive association between unemployment and attempted suicide. This study investigated transitions of employment status among suicide attempters during the severe economic recession. The main research question was whether inequality in the labour market also prevails among as selected a population as suicide attempters. The material consisted of 2495 persons who attempted suicide during 1989-1994 in Helsinki, Finland. Logistic regression analysis and survival analysis were used. Unemployment rates among suicide attempters were higher than in the general population, male rates being higher than female rates throughout the recession. There were significant changes in the employment status of the entire attempted suicide population from 1989 to 1994, especially in terms of the transition from employment to unemployment. Gender, age and education level predicted exit from the labour market. Among suicide attempters young middle-aged men with low education had the highest risk of unemployment.
