Gender, work roles and psychosocial work characteristics as determinants of health.

This paper aims to identify gender similarities and differences in psychosocial work characteristics for those in and out of paid employment, to inform research on possible health-related effects. Specifically five questions are addressed: do women report poorer work characteristics than men; are gender differences related to specific characteristics; do work characteristics differ between full- and part-time women workers and between those in paid and unpaid work; are socio-economic gradients in work characteristics similar for men and women; and, if there are gradients, do they differ between women in paid and unpaid work? Analyses are based on the 33 year follow-up of the 1958 British birth cohort. Four psychosocial work characteristics were examined: learning opportunities, monotony, pace of work, and flexibility of breaks. Women reported more negative work characteristics than men, primarily because of differences in learning opportunities (26% lacked opportunity compared with 13% of men) and monotonous work (47 and 31% respectively). Women in full-time employment reported fewer negative characteristics (27%) than part-time (39%) or home-workers (36%). Home-workers had fewer opportunities for learning (36%) and greater monotony (49%) than paid workers (21 and 22% respectively), however fewer home-workers reported inability to control the work pace (11% compared to 23%) and inflexibility of breaks (21% compared to 47%). Socio-economic gradients in work characteristics were similar among men and women, except for flexibility of break times. A socio-economic gradient in work characteristics was found for full- and part-time workers, but not among home-workers. Differences in self reported health were also examined: a social gradient was found for all employment status groups, being strongest for home-workers despite the absence of a gradient in negative work characteristics. In conclusion, these marked gender differences in psychosocial work characteristics need to be considered in future research on work and health.

New low back pain in nurses: work activities, work stress and sedentary lifestyle.

BACKGROUND: Low back pain is common among nurses. Previous studies have shown that the risk of low back pain increases rapidly with greater amounts of physical work and psychological stress, but is inversely related to leisure activities. However, these previous studies were predominantly retrospective in design and not many took account of three factors simultaneously. AIMS: This 12-month prospective study examined the relationships between work activities, work stress, sedentary lifestyle and new low back pain. METHODS: A total of 144 nurses from six Hong Kong district hospitals completed a face-to-face baseline interview, which was followed-up by a telephone interview. The main study measures were demographic characteristics, work activities, work stress, physical leisure activities and the nature of new low back pain during the 12-month follow-up period. Level of work stress, quality of relationships at work, level of enjoyment experienced at work, and work satisfaction were self-reported. RESULTS: Fifty-six (38.9%) nurses reported experiencing new low back pain. Sedentary leisure time activity was not associated with new low back pain. Being comparatively new on a ward (adjusted relative risk 2.90), working in bending postures (adjusted relative risk 2.76) and poor work relationships with colleagues (adjusted relative risk 2.52) were independent predictors of new low back pain. CONCLUSION: The findings of this study suggest that low back pain is a common problem in the population of nurses in Hong Kong. Being comparatively new on a ward, bending frequently during work and having poor work relationships with colleagues are independent predictors of new low back pain. Training for high-risk work activities and ergonomic assessment of awkward work postures are essential. Moreover, relaxation and team-building workshops for nurses, especially those who are less experienced in the type of work on their current ward, are recommended.

Observations of working postures in garages using the Ovako Working posture Analysing System (OWAS) and consequent workload reduction recommendations.

The working postures of mechanics (n = 84) in 42 garages were observed using the Ovako Working posture Analysis System (OWAS). During observation, both working postures and work activities were recorded. A computer program was developed for the data analyses. Using this program it is possible to calculate the working posture load for each work activity and the contribution of a specific activity to the total working posture load. This is a substantial extension of the original OWAS method. Five out of 19 observed postures of the body members were classified as Action Category 2, which suggests they were slightly harmful to the musculoskeletal system and likely to cause discomfort. Of the so-called typical working postures, 31.9% was classified in Action Category 2, suggesting that during a substantial part of the working day typical working postures occur which are at least slightly harmful to the musculoskeletal system. Moreover, those work activities principally causing the workload to fall in OWAS' higher Action Categories were identified. For each of these three work activities an alternative work method was observed. The data show that in all three work activities the use of a vehicle lift reduces the number of poor working postures thereby reducing the load on the musculoskeletal system.

Work load and individual factors affecting work ability among aging municipal employees.

The effects of work stressors, individual characteristics, symptoms, and diseases on work ability were studied among 4255 municipal employees. Work ability was assessed by a work ability index in two cross-sectional inquiries, one in 1981 and the other in 1985. The most impairing for work ability were mental symptoms and musculoskeletal disease. Among the work stressors, high physical demands at work, poor physical work environment, and lack of freedom were associated with impaired work ability. Muscular work, disturbing temperatures at the workplace, and lack of freedom particularly affected employees with disease, whereas poor work postures and role conflicts at work were particularly injurious for healthy employees. The worst situation was observed when a worker with many symptoms and disease was exposed to many different work stressors. Life satisfaction, sitting work posture, a good basic education, and physical exercise during leisure time were associated with good work ability.

Work-system risk factors for permanent work disability among home-care workers: a case-control study.

OBJECTIVE: There is a growing need for home-care services in western societies. As home-care workers show high levels of absence related to poor health it is important that we broaden our knowledge about what factors in the work system contribute to this. The aim of this study was to explore and estimate the impact of the work system on permanent work disability and its relative importance compared with home-life risks among home-care workers. METHODS: The cases (617 subjects) were all home-care workers in Sweden, whose disability pension was approved in 1997 or 1998. The controls (771 subjects) were home-care workers still working. We used a questionnaire to gain situation-specific information on working life and home life 5 and 15 years before disability pension entitlement. RESULTS: The most important risk factors in the work system were poor ergonomic/lifting conditions, time pressure and lack of professional caring technique. Fifteen years prior to disability pension entitlement, insufficient management (odds ratio (OR) 95%, CI 2.6[1.6;4.2]) and relational problems at work were also risk factors. Five years before disability pension entitlement, poor organisational support (4.1 [2.5;6.7]), opportunities for co-working and working climate (3.5 [2.4;5.2]) were also strongly related to a persisting work ability. The magnitude of exposure to a number of risk factors had an increased effect (highest 13.8 [5.6-33.8]). The strongest risk factor in home life was little opportunity to rest from work (4.9 [3.0;8.0]). The risk factors in working life were robust to the inclusion of the grouped risk factors of home life. CONCLUSIONS: The conclusion was that risk factors related to the work system are, alone, strongly related to permanent work disability among home-care workers. Also, exposure to several of the risk factors constitutes a notably strong risk for permanent work disability.

The work of accident and emergency nurses: Part 2. A & E maxims: making A & E work unique and special.

An ethnomethodological study was undertaken to explore the work of Accident and Emergency (A & E) nurses; the aim of which was to analyse the ordinary, taken for granted, everyday work of those practising A & E nursing. In this second paper on the work of A & E nurses, the specific rules or maxims of nursing work in A & E are introduced. From the analysis of materials gained: fieldwork notes, observations of nurses at work and conversations, a number of maxims of A & E nursing work were identified. Maxims direct, instruct and make nurses accountable for their work and the ways in which it gets done. That is, the presence of maxims underpinning A & E nursing work ensure that A & E nursing is seen and heard as a specific type of work with its own unique approach to talk and organization. Being aware of the maxims of A & E nursing work is not the concern of the nurse practising A & E nursing on a daily basis. Implicit and explicit reference to the maxims when talking about and doing the work provides nurses with impressions of who can do the job. Non-adherence by some nurses to the maxims of A & E nursing work often leads their colleagues to question their commitment to their choice of work setting. Maxims of A & E nursing account for the ways in which the work is seen, heard and talked about. Maxims direct the organization of work and its development within the A & E setting.

Health complaints and working conditions experienced in relation to work and age.

OBJECTIVES: The main objective is to describe the potential health and work problems of the aging employees in the Dutch working population. In this way, we can identify groups at extra risk of specific health problems. METHODS: In The Netherlands, occupational health services gather questionnaire data about work and health as part of periodical occupational health surveys (POHSs). These data from the POHSs of complaints about health and working conditions, aggregated into occupational groups and age categories, are used to provide indications for groups at extra risk of specific health problems. These problems are assessed by overviews of the relation between age and complaints about health and working conditions. RESULTS: Almost all of the health questions show an increase in health complaints with increasing age. White collar workers, especially the high grade white collar workers, usually have lower complaint percentages on health questions than blue collar workers. Female employees have relatively high complaint percentages on the health questions. Differences between occupational groups in the complaints about work and working conditions reflect the differences in work demands and exposure. The relation between age and work complaints is generally inconsistent and weak. The complaint percentages on work questions of female employees tend to be equal to or lower than those of the male employees. CONCLUSIONS: The absence of a clear increase of work complaints with advancing age in the presence of a decrease in health and working capacity may be explained by a selective turnover in the working population, especially in demanding occupations. To enhance the work participation of older employees it may be necessary to reduce the work demands and to increase decision latitude.

[Use of the disability classification "Residual work capacity for part-time work" in an area of Croatia].

A retrospective evaluation of disability was carried out in a group of workers with residual work capacity for part-time work from the region of Slavonski Brod over a ten-year period. The evaluation comprised disability assessment, estimation of the reliability of primary diagnosis with respect to disability assessment, and determination of the period between the assessment of residual work ability for part-time work and retirement due to disability. The disability category "residual work capacity for part-time work" was assigned to 1,029 persons, and was most frequently caused by cardiovascular diseases. Disability pension was based mostly on the diagnoses of mental disorders and cardiovascular diseases and was received by 1,365 persons. With part-time workers who had their residual work ability assessed on the basis of cardiovascular diseases and mental disorders, working part-time was only a temporary, short-term solution, because as soon as within a year, after a regular check-up, they were given disability pension owing to deterioration of primary disease. On the other hand, workers with diseases of the locomotor system as primary diagnosis, who had worked part-time for several years, often had disability pension granted because of some other disease. A detailed analysis among 426 still active workers with residual work capacity showed disability to have been assessed mostly on the ground of diseases of the locomotor system. Functional disorders were usually light to moderate, and working conditions often inappropriate. It is considered that the categories "residual work capacity with full-time work at a more appropriate workplace", with a change of occupation or without it, and "altered work capacity" would have been better applicable in the majority of cases.

Effects of musculoskeletal work load and muscle strength on strain at work in women and men aged 44 to 58 years.

The effects of musculoskeletal work load and muscle strength on strain at work were analysed among 60 women and 69 men (mean age 52 +/- 3.4) in municipal jobs in Finland. The musculoskeletal work load was determined by analysing the jobs by a job description method. The maximal isometric hand grip strength was assessed with a manometer, trunk flexion and trunk extension strength with a dynamometer, and dynamic trunk flexion endurance strength with a sit-up test. Heart rate was registered continuously and ratings of perceived exertion were determined 4 times during the work shift. The results revealed that high musculoskeletal work load was systematically and significantly related to high strain at work in both sexes. A high mean heart rate related to an individual's range in women was an interaction effect of high work load and low hand grip strength or low trunk flexion strength. Among men, both high mean and maximal heart rates in relation to the heart rate range was due to the interaction effects of high work load and low trunk extension strength. The interaction of work load and strength was not systematically related to the ratings of perceived exertion during work. It was concluded that the musculoskeletal work load exerted the main effects on the cardiorespiratory and perceived strains at work. The interaction effects of work load and strength on strain depended on the sex and the muscle group in the studied work load level of elderly municipal employees.

The effects of eye and limb movements on working memory.

Three experiments examined the role of eye and limb movements in the maintenance of information in spatial working memory. In Experiment 1, reflexive saccades interfered with memory span for spatial locations but did not interfere with memory span for letters. In Experiment 2, three different types of eye movements (reflexive saccades, pro-saccades, and anti-saccades) interfered with working memory to the same extent. In all three cases, spatial working memory was much more affected than verbal working memory. The results of these two experiments suggest that eye movements interfere with spatial working memory primarily by disrupting processes localised in the visuospatial sketchpad. In Experiment 3, limb movements performed while maintaining fixation produced as much interference with spatial working memory as reflexive saccades. These results suggest that the interference produced by eye movements is not the result of their visual consequences. Rather, all spatially directed movements appear to have similar effects on visuospatial working memory.

Work, family socioeconomic status, and growth among working boys in Jordan.

AIMS: To describe the work, family socioeconomic characteristics, and growth of a representative sample of working children in Jordan. METHODS: In a cross sectional survey of growth and health, 135 working children (aged 10-16 years) were studied in the areas of Irbid, Jarash, and North Jordan Valley. The children and their parents were interviewed and data collected on length of working week, income earned by the child, duration of work in years, age of starting work, type of work, child's smoking status, and family socioeconomic status. RESULTS: The mean age of the children was 13.3 years; 14.8% had started work before the age of 10 and 12.6% had been working for more than four years. Mean income was 34 Jordanian Dinars but 6.7% were unwaged; 34% were working more than 60 hours per week, and 85.9% more than 40 hours. Monthly income and working hours were positively correlated with the age of the child. There was no correlation between age and smoking status; 37.8% smoked more than five cigarettes per day. Mean height and weight z scores were -0.365 and -0.081 of the UK standard respectively. Packed cell volume was within the anaemic range in 34.1% of children. CONCLUSIONS: In Jordan many children start work at an early age and work long hours for little or no income. Stunting and anaemia are common and many are established smokers. Relevance of these findings for social policy and health care of working children in Jordan and elsewhere is discussed.

[Trends in research and prevention policies for work-related musculoskeletal disorders at the European Agency for Safety and Health at Work (EU-OSHA)].

The European Agency for Safety and Health at Work (EU-OSHA) has been working on matters related to occupational health problems in 15 European Union (EU) member states. EU-OSHA established 10 topic centers on work and health research in 1998. One of the topic centers is assigned for research and information on work-related musculoskeletal disorders. The present report is written because such activities of EU-OSHA are scarcely known in Japan. Work-related musculoskeletal disorders have become a very serious problem in EU member states, i.e., 30% of workers complain of backache, and 17% complain of muscular pains in their arms and legs. The affected workers not only suffer at work but also in their home life. The economic costs of all work-related ill health range from 2.6 to 3.8% of the gross national product, and work-related musculoskeletal disorders constitute 40-50% of this. Therefore EU member states consider that prevention of work-related musculoskeletal disorders in itself is an extremely good economic policy. EU-OSHA published "Work-related neck and upper limb musculoskeletal disorders" in 1999, and "Research on work-related low back disorders" in 2000. These publications suggest various preventive methods which can be introduced in practice at work. One of the most remarkable things in EU-OSHA's activities for work-related musculoskeletal disorders is that EU-OSHA has been trying hard to introduce the results of its research into real policies for EU member states by several means, i.e., held a seminar participated in by policy makers, representatives of trade unions, and researchers from EU member states, and sent seminar resolutions to politicians who are responsible for employment and social affairs. Finally the resolution has been adopted in a new social affairs policy by the EU parliament and will be put into force during 2002. Work-related musculoskeletal disorders will remain one of the most serious occupational problems in EU member states, and EU-OSHA will continue to pay close attention to it.

Prevalence and consequences of low back problems in The Netherlands, working vs non-working population, the MORGEN-Study. Monitoring Project on Risk Factors for Chronic Disease.

OBJECTIVE: To study the burden of illness of low back problems--prevalence and consequences--in the working and the non-working population. METHODS: Data from the Monitoring Project on Risk factors for Chronic Diseases, the MORGEN-study, were used. This project provided data on a probability sample of the general population aged 20-59 y in the Netherlands. Cross-sectional questionnaire data on 6317 men (24% non-working) and 7505 women (47% non-working) gathered over the period 1993-1995 were analysed. RESULTS: The 12 month period prevalence of low back problems for the working and non-working population was 44.4% and 45.8% for men, and 48.2% and 55.0% for women. Larger differences were found for chronic low back problems, and activity limitation and use of health services due to low back problems. More than one-third of those who were disabled were so because of low back problems. When those unable to work because of disability (work disabled) were excluded, the prevalence and consequences of low back pain were still higher in the non-working group in comparison with the working population. Most of the non-working women were housewives and this group was both large in size and had a high prevalence of low back problems. CONCLUSIONS: Among the men studied, more than a quarter of the total burden of low back problems in those aged 20-59 y were found in the non-working population, among women this was 50%. Both research on causes and determinants of low back pain and the development of preventive actions--now being extensively focused on the working population--should also be translated to the non-working population.

Long hours in paid and domestic work and subsequent sickness absence: does control over daily working hours matter?

OBJECTIVES: To explore the associations of working hours (paid, domestic, commuting, and total) with sickness absence, and to examine whether these associations vary according to the level of employee control over daily working hours. METHODS: Prospective cohort study among 25 703 full-time public sector employees in 10 towns in Finland. A survey of working hours and control over working hours was carried out in 2000-01. The survey responses were linked with register data on the number of self-certified (< or =3 days) and medically certified (>3 days) sickness absences until the end of 2003. Poisson regression analyses with generalised estimating equations were used to take into account the fact that the employees were nested within work units. Adjustments were made for work and family characteristics and health behaviour. The mean follow-up period was 28.1 (SD 8.1) months. RESULTS: Long domestic and total working hours were associated with higher rates of medically certified sickness absences among both genders. In contrast, long paid working hours were associated with lower rates of subsequent self-certified sickness absences. Long commuting hours were related to increased rates of sickness absence of both types. Low control over daily working hours predicted medically certified sickness absences for both the women and men and self-certified absences for the men. In combinations, high control over working hours reduced the adverse associations of long domestic and total working hours with medically certified absences. CONCLUSIONS: Employee control over daily working hours may protect health and help workers successfully combine a full-time job with the demands of domestic work.

Work hardening and work conditioning interventions: do they affect disability?

The purpose of this article is to review the research on the effectiveness of work hardening and work conditioning programs. Twelve studies of work hardening and work conditioning programs in the United States and abroad were reviewed. One study produced convincing evidence in a randomized study that a work conditioning program was useful in producing a higher percentage of return to work and an earlier return to work in a group of patients off work for at least 2 months. Another study demonstrated that a work hardening program increased the rate of return to work by 52% in patients off work for greater than 4 months. Most of the other studies reviewed suggested positive results, but more carefully documented, randomized, and controlled studies are needed to support the efficacy of these programs and to determine the optimum and most cost-effective work hardening and work conditioning interventions.

Working hours, work-life conflict and health in precarious and "permanent" employment.

OBJECTIVE: The expansion of precarious employment in OECD countries has been widely associated with negative health and safety effects. Although many shiftworkers are precariously employed, shiftwork research has concentrated on full-time workers in continuing employment. This paper examines the impact of precarious employment on working hours, work-life conflict and health by comparing casual employees to full-time, "permanent" employees working in the same occupations and workplaces. METHODS: Thirty-nine convergent interviews were conducted in two five-star hotels. The participants included 26 full-time and 13 casual (temporary) employees. They ranged in age from 19 to 61 years and included 17 females and 22 males. Working hours ranged from zero to 73 hours per week. RESULTS: Marked differences emerged between the reports of casual and full-time employees about working hours, work-life conflict and health. Casuals were more likely to work highly irregular hours over which they had little control. Their daily and weekly working hours ranged from very long to very short according to organisational requirements. Long working hours, combined with low predictability and control, produced greater disruption to family and social lives and poorer work-life balance for casuals. Uncoordinated hours across multiple jobs exacerbated these problems in some cases. Health-related issues reported to arise from work-life conflict included sleep disturbance, fatigue and disrupted exercise and dietary regimes. CONCLUSIONS: This study identified significant disadvantages of casual employment. In the same hotels, and doing largely the same jobs, casual employees had less desirable and predictable work schedules, greater work-life conflict and more associated health complaints than "permanent" workers.

Work conditions and socioeconomic inequalities in work ability.

OBJECTIVES: The objective of this study was to investigate socioeconomic inequalities in work ability among municipal employees and the contribution of work conditions to these inequalities. METHODS: The subjects were employees of the City of Helsinki and were all over 40 years of age. Data (N=1,827) were collected in the age-group-based medical check-ups by occupational health personnel. Work ability was measured with a work ability index. The association between the work ability index with socioeconomic status was examined by fitting logistic regression models. RESULTS: There was a consistent gradient in work ability, lower socioeconomic groups having poorer work ability. Adjusting for physical stress accounted for a substantial part of the socioeconomic inequalities. Adjusting for possibilities for influence and development at work accounted for some of the difference between white-collar and blue-collar employees, but not for differences between the white-collar subgroups among the women. Mental stress and problems in the social environment were not clearly associated with the inequalities. CONCLUSIONS: Socioeconomic inequalities in work ability among municipal employees correspond to the inequalities in ill health found in general populations. Physical stress at work explained a large part of the inequality. Poor possibilities to influence one's work contributed to the excess of lowered work ability among the blue-collar employees, but not to the inequalities between white-collar subgroups of women. Apart from physical workload, work conditions did not explain socioeconomic inequalities between white-collar subgroups of women.

[Relationship between the personal factors and work ability of different work category workers].

OBJECTIVE: To assess the relationship between the personal Factors and work ability of different work category workers. METHODS: A test of work ability in various work category and age group was carried out with work ability index (WAI) for 5648 workers. RESULTS: 1. The score of WAI of physical work, mixed physical and mental work category for female was significantly higher than those for male (P < 0.01), but the score of WAI of mental work category in male was higher than that for female (P < 0.05). 2. Two-way ANOVA for the different sex revealed that the score of WAI of various work category and age group, education category group, work duration Group, marital Status Group was statistically significant difference (P < 0.01). The level of work ability, except that for the age group of 30 yr.- and 40 yr.-, decreased with age (P < 0.05). The score of WAI, except that for the workers of 10 yr.-, and 20 yr.- group, decreased with work duration (P < 0.05). The score of WAI was obviously higher in the secondary and college education category than elementary category (P < 0.05). The score of WAI for the married and divorced was lower than that for the unmarried (P < 0.05). CONCLUSION: Different measures relevant to the influencing factors should be taken to improve the work ability.
