RESUMEN
We studied the developmental trajectories of satisfaction with work-family reconciliation (WFS) and their associations with family-related factors and quality of life measures among municipal employees. The study was based on the Helsinki Health Study of municipal employees of the City of Helsinki in 2001-02 and its follow-up surveys in 2007, 2012, and 2017. Employees aged 40-50 at baseline and working at all timepoints were analysed (n = 1681, 84% women). Growth Mixture Models were applied to identify trajectories of WFS (dissatisfied vs. satisfied). Associations of family-related and quality-of-life factors (physical functioning and emotional well-being) with the WFS trajectories were studied using log-binomial regression models, adjusting for sociodemographic and lifestyle variables. Two WFS trajectories, low (women 45%; men 53%) and high were identified. In a fully adjusted model among women, having ≥1 children aged 0-6 years was associated with increased odds of belonging to the low WFS trajectory (OR 1.52, 95% CI 1.19-1.95). Among men, having ≥1 children aged 7-18 was associated with decreased odds (0.39, 0.19-0.80). High emotional well-being was inversely associated with the low WFS trajectory among both genders (women 0.32, 0.23-0.45; men 0.20, 0.09-0.46). High physical functioning (0.59, 0.42-0.83) was inversely associated with the low WFS trajectory among women only. Less than half of the women and more than half of the men participants belonged to a low WFS trajectory, which associated with the age of children in the family and quality-of-life measures.
RESUMEN
BACKGROUND: . Decreased work ability due to mental disorders is a growing concern in Europe. We studied the role of work-family conflicts in association with long-term sickness absence due to mental disorders (LTSA-MD). METHODS: . Baseline data were extracted from the Helsinki Health Study for women aged 40 to 55 in full-time work in 2001 - 2002 (N = 2386). Questionnaire responses were linked with register data from the Social Insurance Institution of Finland on SA spells due to mental disorders during 2004-2010. We studied an overall question on satisfaction with combining work and family (WFS) and composite scores of work-to-family conflicts (WTFC) and family-to-work-conflicts (FTWC), and their components in association with the first certified SA spell (≥ 12 calendar days) due to a mental disorder during the follow-up. We performed Cox regression analyses with hazard ratios (HR) and their 95% confidence intervals (CI) adjusted for sociodemographic factors, work schedule, perceived mental and physical strenuousness at work, and self-rated health. First, we examined all participants, and second, only those who reported no prior mental disorder. RESULTS: . Poor work-family satisfaction (WFS) was associated with subsequent LTSA-MD, adjusting for all covariates (HR 1.60; 95% CI 1.10-2.16). Both high WTFC (1.64; 1.15-2.23), and high FTWC (1.43; 1.02-2.00) increased the probability of LTSA-MD in the full model. When participants with prior mental disorder were excluded, the association between poor WFS and WTFC with LTSA-MD retained while that between FTWC and LTSA-MD attenuated; however, two items of the FTWC were still associated with LTSA-MD: 'Family worries and problems distract you from your work' and 'Family matters prevent you from sleeping enough to do your job well'. Of the WTFC items, the following remained associated with LTSA-MD: 'Problems at work make you irritable at home' and 'Your job takes so much energy you do not feel up to doing things that need attention at home'. The experience of decreased time for work or family did not associate with LTSA-MD. CONCLUSIONS: . Among female municipal employees, dissatisfaction with combining work and family and both work-to-family and family-to-work conflicts were associated with subsequent long-term sickness absence due to mental disorders.

OBJECTIVE: To estimate the effects of excess body mass and leisure time physical activity on the incidence and persistence of chronic pain. DESIGN: A prospective cohort study. METHODS: As a part of the Finnish Helsinki Health Study, we included three cohorts of employees of the City of Helsinki (18,562 observations) and defined incident chronic pain as having pain in any part of the body for more than three months at follow-up in participants without chronic pain at baseline (N = 13,029 observations). Persistent chronic pain was defined as having pain for more than three months at both baseline and follow-up (N = 5,533 observations). RESULTS: Overweight (adjusted odds ratio [OR] = 1.18, 95% confidence interval [CI] = 1.06-1.31) and obesity (OR = 1.65, 95% CI = 1.45-1.88) increased the incidence of chronic pain. Moreover, overweight (OR = 1.16, 95% CI = 1.02-1.32) and obesity (OR = 1.48, 95% CI = 1.26-1.74) increased the risk of persistent chronic pain. Vigorous leisure time physical activity reduced the incidence of chronic pain (OR = 0.85, 95% CI = 0.75-0.96). Physical activity did not influence the risk of persistent chronic pain. Furthermore, overweight/obesity modified the effect of leisure time physical activity on incident chronic pain. Inactive overweight or obese participants were at the highest risk of chronic pain (OR = 1.71, 95% CI = 1.40-2.09), while the OR dropped to 1.44 (95% CI = 1.19-1.75) in moderately active overweight or obese participants and to 1.20 (95% CI = 0.97-1.47) in highly active overweight or obese participants. CONCLUSIONS: Obesity not only increases the risk of developing chronic pain, but also increases the risk of persistent pain, while leisure time physical activity reduces the risk of developing chronic pain.

BACKGROUND: We aimed to investigate trajectories of mobility limitations (MLs) over a period of 24 years. In addition, we aimed to study how shift work and leisure-time physical activity (LTPA) in midlife predict assignment to MLs trajectories separately for those retired on statutory pensions (SPs) and on disability pensions (DPs). METHODS: Subjects who responded MLs questionnaires (1985-2009, N = 3048) in Finnish Longitudinal Study on Aging Municipal Employees were included in this prospective cohort study. LTPA and shift work were measured during baseline. International Classification of Functioning was used to code MLs. Growth mixture modeling was used to identify the trajectories of MLs. Odds ratio (OR) and their 95% Confidence interval (CI) were assessed by using multinomial logistic regression. RESULTS: We identified four trajectories of MLs, namely low persistent, low increasing, high decreasing and high persistent. Among the SP recipients, shift work with night shifts was associated with an increased risk (adjusted OR 1.49; 95% CI 1.03-2.14) of belonging to the high persistent MLs trajectory. The inactive LTPA (SP: OR 5.99, 95% CI 3.39-10.58, DP: OR 6.81, 95% CI 2.52-18.43) was similarly associated with high persistent MLs trajectory. CONCLUSION: Nearly two-thirds of the people retired due to disability belonged to high MLs trajectory. High persistent MLs trajectory was associated with physical inactivity in midlife among those retired on SP and on DP. Shift work with night shift predicted high persistent MLs in SP strata. Active involvement in LTPA during midlife could be beneficial to spend MLs free later life.

OBJECTIVES: We studied the developmental trajectories of multisite musculoskeletal pain (MSP) to learn whether pain in midlife persists to old age, and whether pain trajectories associate with midlife work or lifestyle exposures or retirement from work. METHODS: Municipal employees aged 44-58 years were studied in 1981 (n=6257) with follow-ups in 1985, 1992, 1997 and 2009. Pain in the neck, low back, and upper and lower limbs was assessed in each survey. Trajectories of the number (0-4) of pain sites were defined using growth mixture modelling (n=3093). Workload, lifestyle and morbidity were elicited by questionnaire and retirement from registries. Associations of baseline factors with pain trajectories were assessed by multinomial logistic regression. Cumulative hazard curves for retirement by trajectory group were calculated. RESULTS: Three trajectories of pain over 28 years emerged: low (25%), moderate (52%) and high-decreasing (23%). In the latter, the number of pain sites first decreased sharply, stabilising to a moderate level after most subjects had retired. The disability pension rate was highest in this trajectory, which associated with high baseline morbidity, particularly musculoskeletal disorder (OR 8.06; 95% CI 5.97 to 10.87). Also high biomechanical exposure (2.86;95% CI 2.16 to 3.78), high job demands (1.79; 95% CI 1.39 to 2.30), high job control (OR 0.70; 95% CI 0.54 to 0.90), body mass index (BMI) ≥25.0 kg/m2 (1.40; 95% CI 1.09 to 1.80) and low leisure-time physical activity (LTPA) (1.39; 95% CI 1.09 to 1.78) at baseline were associated with this trajectory. However, high LTPA and BMI in repeated surveys also associated with the high-decreasing trajectory. CONCLUSION: MSP in midlife often persists to old age. However, high widespreadness of pain may decrease with retirement from work.

BACKGROUND: Previous studies have not distinguished between different alcohol-use histories, which could have contributed to the current inconsistent evidence regarding the relationship between alcohol use and subsequent sickness absence. We thus examined alcohol use and subsequent diagnosis-specific sickness absence in groups with different levels of alcohol use, as well as in lifelong abstainers, former drinkers, and people with clinical alcohol use disorders. METHODS: The data of the population-based Health 2000 Survey (BRIF8901) of 3666 Finns aged 30-55 were linked with national registers on medically certified sickness absences lasting for > 10 working days (long-term) for all causes (2000 - 2010) and for mental or musculoskeletal disorders (2004-2010), as well as with registers on pensions and death (2000-2010). Alcohol use was assessed by questionnaire. Chronic somatic diseases were evaluated at baseline in a clinical examination, and common mental and alcohol use disorders using the Composite International Diagnostic Interview (CIDI). Cox regression analyses were conducted with censoring for death and retirement from work. RESULTS: During an average 10-year follow-up, 56.0% of the participants had at least one long-term sickness absence period. Compared with light drinkers, those having an alcohol use disorder had increased risk of all-cause sickness absence (HR = 1.27; 95% CI = 1.04 - 1.54) and sickness absence due to mental disorders (HR = 2.16; 95% CI = 1.39 - 3.35), when somatic and mental disorders as well as demographic, lifestyle-related and occupational factors at baseline were accounted for. Lifelong abstainers did not differ from light drinkers. Also high-volume drinking (HR = 1.52; 95% CI 1.03 - 2.25) and former drinking (HR = 1.57; 95% CI = 1.15 - 2.15) were associated with long-term sickness absence due to mental disorders. Alcohol use was not predictive of sickness absence due to musculoskeletal disorders. CONCLUSIONS: These results highlight the need to distinguish between former drinking and lifelong abstinence, as only former drinking was associated with sickness absence. Alcohol use disorder and high-volume drinking were strongly predictive of sickness absence due to mental disorders. Identifying people with excessive alcohol use e.g. in occupational health care, and mapping and supporting their mental health may help in preventing sickness absences.

We investigated how work-related biomechanical exposure and job strain in midlife separately and jointly predicted back and degenerative musculoskeletal diseases (MSDs). A total of 6,257 employees participated in the Finnish Longitudinal Study on Aging Municipal Employees (FLAME) in 1981 and were followed up for 28 years. Risk ratios and the relative excessive risk due to interaction and 95% confidence intervals were modeled for separate and joint prediction estimates, respectively. After adjustment for confounders, job strain predicted degenerative MSDs among women after 4 and 11 years of follow-up. After 11 years, both exposures predicted both types of MSDs among men. Joint exposure predicted both types of MSDs after 4 years among women (for back MSDs, risk ratio (RR) = 1.58, 95% confidence interval (CI): 1.15, 2.18; for degenerative MSDs, RR = 1.59, 95% CI: 1.21, 2.07) and men (for back MSDs, RR = 1.50, 95% CI: 1.05, 2.15; for degenerative MSDs, RR = 1.61, 95% CI: 1.16, 2.22) and both types of MSDs after 11 years (for back MSDs, RR = 1.72, 95% CI: 1.21, 2.43; for degenerative MSDs, RR = 1.68, 95% CI: 1.25, 2.46) among men only, but the relative excessive risk due to interaction was not significant throughout. However, after 28 years, the separate and joint exposures did not predict MSDs. Workplace interventions should be focused on reducing job strain along with biomechanical exposure for possible prevention of MSDs in working life and around the time of retirement, but there may be other pathways of onset of MSDs in old age.

BACKGROUND: Osteoarthritis (OA) is the most common degenerative joint disease afflicting people in the Western world and has a strong genetic influence. The aim of this study was to examine the association of two known functional polymorphisms in the TGF-ß inhibiting genes, asporin (ASPN) and cartilage intermediate layer protein (CILP), with hand OA and potential gene-occupational hand loading interaction. RESULTS: Statistically significant interaction of the CILP rs2073711 T and ASPN D15 alleles with hand OA was observed (OR = 2.48, 95% CI 1.27-4.85, p = 0.008) in a Finnish hand OA cohort of 543 women (aged 45-63). When stratified by variation in working tasks, low variation of working tasks increased the risk further (OR = 3.00, 95% CI 1.35-6.66, p = 0.007). Based on the analysis of ASPN and CILP protein-coding regions, functional studies were performed with one observed variant, rs41278695 in the ASPN gene. Analyses showed that bone morphogenetic protein 2 (BMP2) mediated expression of aggrecan (Agc1) and type II collagen (Col2a1) was significantly suppressed (p = 0.011 and p = 0.023, respectively) in a murine chondrocytic cell line (ATDC5) with cells stably expressing ASPN rs41278695. CONCLUSIONS: The carriage of either ASPN D15 or CILP rs2073711 TT is associated with increased risk of symmetrical hand OA, particularly in individuals with low variation in work tasks. ASPN rs41278695 SNP had an effect on Agc1 and Col2a1 gene expression when induced with BMP-2 suggesting an effect on the cartilage extracellular matrix composition.

OBJECTIVE: To investigate the developmental pathways of multisite musculoskeletal pain (MSP) and the effect of physical and psychosocial working conditions on the development of MSP trajectories. METHODS: The study was conducted among food industry workers (N=868) using a longitudinal design. Surveys were conducted every 2â years from 2003 to 2009. The questionnaire covered MSP, physical and psychosocial working conditions (physical strain, environmental factors, repetitive movements, awkward postures; mental strain, team support, leadership, possibility to influence) and work ability. MSP as an outcome was defined as the number of painful areas of the body on a scale of 0-4. Latent class growth modelling and multinomial logistic regression were used to analyse the impact of working conditions on MSP pathways. RESULTS: Five MSP trajectories (no MSP 35.6%, persistent MSP 28.8%, developing MSP 8.8%, increasing MSP 15.3% and decreasing MSP 11.5%) were identified. In a multivariable model, the no MSP pathway was set as the reference group. High physical strain (OR 3.26, 95% CI 2.10 to 5.04), poor environmental factors (3.84, 2.48 to 5.94), high repetitive movements (3.68, 2.31 to 5.88) and high mental strain (3.87, 2.53 to 5.92) at baseline predicted the persistent MSP pathway, allowing for poor work ability (2.81, 1.84 to 4.28) and female gender (1.80, 1.14 to 2.83). High physical strain and female gender predicted the developing MSP pathway. High physical strain, poor environmental factors and high repetitive movements predicted the increasing and decreasing MSP pathways. CONCLUSIONS: A substantial proportion of individuals reported having persistent MSP, and one-third reported changing patterns of pain. Adverse physical working conditions and mental strain were strongly associated with having high but stable levels of MSP.

OBJECTIVES: Osteoarthritis (OA) is a joint disease common in the elderly. There is a prior functional evidence for different matrix metalloproteinases (MMPs), such as MMP8 and MMP9, having a role in the breakdown of cartilage extracellular matrix in OA. Thus, we analyzed whether the common genetic variants of MMP8 and MMP9 contribute to the risk of OA. MATERIALS AND METHODS: In total, 13 common tagging single-nucleotide polymorphisms (SNPs) were studied in a discovery knee OA cohort of 185 cases and 895 controls. For validation, two knee OA replication cohorts and two hand OA replication cohorts were studied (altogether 1369 OA cases, 4445 controls in the five cohorts). The χ(2) test for individual study cohorts and Cochran-Mantel-Haenszel test for combined meta-analysis were calculated using Plink. RESULTS: The rs1940475 SNP in MMP8 showed suggestive association in the discovery cohort (OR = 0.721, 95% CI 0.575-0.906; p = 0.005). Other knee and hand OA replication study cohorts showed similar trend for the predisposing allele without reaching statistical significance in independent replication cohorts nor in their meta-analysis (p > 0.05). Meta-analysis of all five hand and knee OA study cohorts yielded a p-value of 0.027 (OR = 0.904, 95% CI 0.826-0.989). CONCLUSIONS: Initial analysis of the MMP8 gene showed suggestive association between rs1940475 and knee OA, but the finding did not replicate in other study cohorts, even though the trend for predisposing allele was similar in all five cohorts. MMP-8 is a good biological candidate for OA, but our study did not find common variants with significant association in the gene.

AIM: Although multisite pain (MSP) often threatens work ability (WA), some of those with MSP retain good WA. Our aim was to identify factors associated with good WA among subjects with MSP. METHODS: A nationally representative sample (the Health 2000-Study, response rate 87%) comprising 3884 occupationally active Finns aged 30-64 years. Data on WA, musculoskeletal pain, physical and psychosocial working conditions, chronic diseases, lifestyle and domestic situation were gathered by questionnaire, interview and clinical examination. Good current WA compared with the lifetime best was defined as ⩾9 on a 0-10 scale. Musculoskeletal pain in 18 body locations was combined into four sites, and thereafter pain in two or more sites was defined as MSP (N=1351). Poisson regression analysis was used to obtain prevalence rate ratios (PRR). RESULTS: Good WA was reported by 48% of the women and 37% of the men with MSP. In a multivariable model good WA was associated with younger age, female gender, physically non-strenuous work (PRR 1.3, 95% CI 1.1-1.5), low job strain (1.2, 1.0-1.4), high supervisor support (1.2, 1.0-1.4), and not having musculoskeletal diseases (1.3, 1.1-1.5), mental disorders (1.4, 1.1-1.9), daytime tiredness (1.4, 1.2-1.7) or economic troubles (1.5, 1.1-1.9). Age-stratified analyses revealed also associations with high coworker support (1.2, 1.0-1.4) and strenuous leisure-time physical exercise (1.2, 1.0-1.4) in those aged 30-44 and low alcohol consumption (1.8, 1.2-2.6) in the age-group 45-64. CONCLUSIONS: Several potentially modifiable factors related to health, work, and lifestyle were associated with good WA among occupationally active subjects with MSP.

INTRODUCTION: We examined the socio-demographic and behavioral determinants of perceived barriers to leisure-time physical activity (LTPA) in a population-based sample of working-aged adults. METHODS: Data comprised the National FINRISK 2002 Study, a population-based health examination study. Analyses were restricted to those aged 25-64 years and who perceived that their amount of LTPA did not reach sufficient levels. They reported barriers to LTPA, defined as a lack of time, motivation and lack of companionship to be active with, as well as high expenses. Age, education, household income, employment status, family type, physical activity, smoking and body mass index (BMI) were included as explanatory variables. RESULTS: Lack of time was the most frequent barrier. Each barrier was explained by a different set of factors that also varied between genders. The strongest and most systematic associations with the barriers were found for age, employment status and family type. Lack of time was less often reported as a barrier among the unemployed, singles without children and older people. Lacking motivation as a barrier was most common among singles without children. High expenses as a barrier was more often reported by the unemployed, and less often reported in the highest income group. CONCLUSIONS: When considering actions to promote LTPA, there is not one single solution, because the perceived barriers vary by population subgroups.

AIMS: Previously, among food industry workers, multisite pain predicted sickness absence (SA) only in those with low biomechanical workload. Here we studied among a wide range of occupations whether the relationship of pain with SA was modified by the level of physical or psychosocial workload. METHODS: A nationally representative sample (Health 2000 Survey) comprised 3420 occupationally active Finns aged 30-55 years. Baseline data on musculoskeletal pain during the preceding month, strenuous work history, current physical workload, job demands, job control, support at work, lifestyle, and chronic diseases were obtained in 2000/2001 by questionnaire, interview, and clinical examination. Musculoskeletal pain in 18 body locations was combined into four sites (neck, upper limbs, low back, and lower limbs) and classified as no pain, single-site pain, and multisite pain (2-4 sites). The data were linked with information from national registers on annual SA periods lasting ≥10 workdays for 2002-2008. Negative binomial regression analysis was used. RESULTS: At baseline, one-third of the study sample reported single-site and one-third multisite pain. Allowing for gender and age, the employees with multisite pain in strata with high physical workload and high job demands tended to have the highest risk of SA, but no statistically significant interactive effects between work factors and pain were observed. Further adjustment for health-related lifestyle and chronic diseases decreased the risk estimates in all strata. CONCLUSION: We did not find evidence for significant modification by physical or psychosocial workload of the relationship between musculoskeletal pain and SA periods lasting ≥10 workdays.

PURPOSE: Occupations during adult life may have long-term effects and subsequently increase the risk of disability in old age. We investigated the associations between job profile groups in midlife and disability in old age for women and men. METHODS: This prospective 28-year follow-up study (1981-2009) examined 2998 municipal employees (1892 women and 1106 men) aged 44-58 years at baseline. A detailed analysis of the demands of 88 occupations based on interviews and observations at the work places was made at baseline. Thirteen job profile clusters emerged. Questionnaire information on health, lifestyle and socio-demographic factors was collected at baseline. In 2009, five Activities of Daily Living and seven Instrumental Activities of Daily Living tasks were assessed. A sum score of '0-12' was calculated using 12 dichotomous tasks where '0' indicates no difficulties in any tasks and '1-12' indicates increasing disability. Negative binomial regression was used to calculate rate ratios (RR) and their 95 % confidence intervals (CIs) for disability due to midlife job profiles. RESULTS: After adjusting for age, socioeconomic, lifestyle and health-related characteristics, women in auxiliary (RR 2.1, 95 % CI 1.4-3.2), home care (2.1, 1.4-3.2), kitchen supervision (2.0, 1.1-3.6) and office (1.6, 1.1-2.4) job profiles had a higher risk of disability in later life than those in administrative jobs. Auxiliary (1.5, 1.1-2.9) and technical supervision (1.7, 1.1-2.7) job profiles carried an increased risk among men. CONCLUSION: Midlife job profiles mainly linked with physically heavy work were strong predictors of disability in later life. In women, office work also increased the risk of disability.

BACKGROUND: To justify alcohol-related health promotion programs and target them at the correct workplaces, it is important to identify occupations with increased risk of severe health outcomes caused by alcohol. METHODS: Data on hospital admissions (854,555 men and 801,653 women) from the Finnish health care register and data on deaths from Statistics Finland from 1 January 2001 to 31 December 2004 were merged with information from the 2000 population census. We assessed the age- and education-adjusted relationship between occupation and the sum of hospitalizations and death primarily caused by alcohol, using Cox proportional hazards regression. We also estimated the fraction of incidence of severe alcohol-induced health outcomes that are attributable to factors related to one's occupation (population attributable fraction). RESULTS: Most of the cases were men (80%), middle-aged and usually had no more than a secondary level of education. When the reference was professionals, who were at the lowest risk, those at increased risk were mostly manual workers in craft work, construction and service. However, we also found several non-manual occupations at a high risk. According to population attributable fraction, the proportion of severe alcohol-induced health outcomes would have been 31% lower among men and 20% lower among women if all occupational groups had been at the same risk as professionals. CONCLUSIONS: We detected considerable occupational differences in alcohol-induced morbidity and mortality among a nationally representative working population. This indicates a need for alcohol-focused health promotion programs in these high-risk occupations.

AIM: According to previous studies, abstinence from alcohol increases the risk of disability retirement (DR). We studied whether former alcohol users' poor mental or physical health might have contributed to this result. METHODS: Prospective population-based study of 3621 occupationally active Finns aged 30-55 years at baseline. Disability pension data for 2000-2011 was retrieved from national pension records. We examined medically certified disability retirement due to all causes and due to mental disorders among lifelong abstainers, former drinkers, those with an alcohol use disorder irrespective of consumption and current users, further classified according to weekly intake of alcohol. Chronic somatic diseases were evaluated in a clinical examination and common mental and alcohol use disorders using the Composite International Diagnostic Interview. Cox regression was used. RESULTS: Neither lifelong abstinence nor alcohol consumption, even at hazardous levels, without alcohol use disorder was associated with disability retirement. Compared with light drinkers, former drinkers' hazard ratio for DR due to mental disorders was 2.67 (95% CI 1.39-5.13), allowing for somatic and mental morbidity, physical and psychosocial workload, health behaviour and socio-demographic factors. The respective hazard ratio of DR due to all causes for those with alcohol use disorder was 2.17 (1.49-3.16) and of DR due to mental disorders 4.04 (2.02 to 8.06). CONCLUSIONS: Lifelong abstinence did not predict disability retirement. Former drinkers and people with alcohol use disorders were at a multi-fold risk of work disability due to mental disorders compared with light drinkers, thus it is important to support their work ability.

AIM: To investigate single-site and multi-site musculoskeletal pain as predictors of future sickness absence due to musculoskeletal disorders (MSD) among blue-collar employees in food industry, and to study to what extent this relationship depends on physical loading at work. METHODS: Survey responses of 901 employees on working conditions and musculoskeletal pain during the past week were linked to their future sickness absence records obtained from the personnel register of a food industry company. Negative binomial regression models were computed to determine associations of pain in one and in multi-site with the number of sickness absence days due to MSD during a four-year follow-up. Analyses were made in the whole cohort and stratified by the occurrence of repetitive movements and awkward postures (low/high). RESULTS: Multi-site pain occurred among 59 % in the total cohort and predicted sickness absence with a rate ratio of 1.48 [95 % confidence interval (CI) 1.21-1.80], adjusted for age, gender, biomechanical and psychosocial working conditions, body mass index and physical exercise. Similar associations were seen in the sub-cohorts with a low occurrence of repetitive movements (RR 2.18, CI 1.69-2.80) and awkward postures (RR 1.78, CI 1.39-2.28), but not in the sub-cohorts with a high occurrence of these exposure. Single-site pain was not predictive of sickness absence. CONCLUSIONS: A very high level of sickness absence in biomechanically strenuous work was found. Multi-site pain predicted sickness absence due to MSD among the employees with low exposure, but not among those with high exposure.

BACKGROUND: high job strain increases the risk of health decline, but little is known about the specific consequences and long-term effects of job strain on old age health. OBJECTIVES: purpose was to investigate whether physical and mental job strain in midlife was associated with hospital care use in old age. METHODS: study population included 5,625 Finnish public sector employees aged 44-58 years who worked in blue- and white-collar professions in 1981. The number of in-patient hospital care days was collected from the Finnish Hospital Discharge Register for the 28-year follow-up period. RESULTS: rates of hospital care days per 1,000 person-years for men were 7.78 (95% confidence interval [CI] 7.71-7.84) for low, 9.68 (95% CI 9.50-9.74) for intermediate and 12.56 (95% CI 12.47-12.66) for high physical job strain in midlife. The corresponding rates for women were 6.63 (95% CI 6.57-6.68), 7.91 (95% CI 7.87-7.95) and 10.35 (95% CI 10.25-10.42), respectively. Rates were parallel but lower for mental job strain. Reporting high physical job strain in midlife increased the risk of hospital care in old age compared with those who reported low job strain, fully adjusted incidence rate ratio 1.17 (95% CI 1.00-1.38) for men and 1.42 (95% CI 1.25-1.61) for women. These associations were robust in analyses confined to hospital care that took place after the employees had turned 65 years. CONCLUSION: exposure to high mental and, particularly, high physical job strain in midlife may set employees on a higher healthcare use trajectory which persists into old age.

STUDY DESIGN: Prospective cohort study. OBJECTIVE: To study the associations between strenuous leisure time physical activity (LTPA) and subsequent hospitalization due to back disorders. Socioeconomic and lifestyle factors are associated with back-related hospitalization, but the significance of strenuous LTPA in the working population is unclear. METHODS: The cohort (n = 902) was drawn from among employees in the metal industry (n = 2,653). Data were collected by a questionnaire and a structured interview on LTPA. Activity regarding strenuous (>500 kcal/h) LTPA was categorized as none, some, and high. Information from national registers on hospitalizations and deaths during 28 years of follow-up was linked to the data. Cox proportional hazards regression was used. RESULTS: Subjects with a high level of strenuous LTPA had a decreased risk of hospitalization due to back disorders (hazard ratio 0.40; 95% CI 0.21-0.79) compared with persons with no strenuous activity, after adjustment for age and gender. The association persisted (0.48; 0.24-0.96) when further adjusted for occupational class, self-reported back diseases, smoking, and body mass index at baseline. CONCLUSION: Strenuous LTPA decreased the risk of inpatient hospital care for back disorders among industrial employees.

BACKGROUND: The development of osteoarthritis (OA) involves inflammation, but the evidence for participation of genes propagating or inhibiting inflammation in the OA process is inconsistent. We investigated the associations of common variants in the TNFα gene, and their interactions with other cytokine genes, with hand OA among Finnish women. METHODS: This cross-sectional study was based on bilateral hand radiographs of 542 female dentists and teachers which were classified according to the presence of OA (radiographic K-L score ≥ 2 in ≥ 3 joints) using reference images. The genotypes were determined by PCR-based methods. The degree of pairwise linkage disequilibrium (LD) and haplotypes were constructed and analyzed by the SNPStats software. The associations between four TNFα SNPs and hand OA were tested using logistic regression adjusting for age, occupation, and BMI, and fitting a log-additive model of inheritance. Gene-gene interactions of TNFα SNPs with IL4R and IL10 SNPs were examined by stratified logistic regression analyses. Possible interactions of the TNFα SNPs with variants in the previously reported IL1ß and IL6 genes in influencing hand OA were also explored. RESULTS: Two TNFα polymorphisms ("-1031" and "-863") were associated with hand OA (OR = 1.45, 95% CI 1.01-2.07 and 1.55, 1.06-2.25, respectively). These associations retained when adjusting further for IL1ß "3954" and IL6 "174". The TNFα G-A-G haplotype was associated with an increased risk of hand OA (1.61, 1.10-2.37, p = 0.01). Interactions were observed between TNFα "-1031" and IL4R Ser503Pro, TNFα "-1031" and IL10 "-1082", and TNFα "-863" and IL10 "-1082" SNPs with regard to hand OA (p = 0.012, p = 0.0068, and p = 0.02, respectively). The carriage of the TNFα "-1031" minor allele doubled the risk (2.01, 1.26 - 3.22) only in women with the IL4R Ser/Ser genotype. Similarly, the TNFα "-1031" and "-863" minor alleles were associated with an increased risk of hand OA only in IL10 G/G or A/A homozygotes (2.54, 1.45-4.47 and 2.60, 1.46-4.62, respectively) but not in heterozygotes (G/A). CONCLUSIONS: Our results suggest that the TNFα gene variants play a role in the etiology of hand OA. In addition, the findings are suggestive of a gene-gene interaction of the TNFα with IL4R and IL10 genes.
