Changes in the structure of health complaints as related to shiftwork exposure

Abstract

Factor analyses of health complaints in groups with different length of shiftwork exposure show that the structure of these complaints changes with increasing shift experience, indicating the emergence of a shift-specific pattern of health complaints. After about 15 years of shiftwork, complaints related to disturbances of circadian-controlled functions can be found in the first factor whereas other complaints have their dominant loadings on a separate factor, representing general, non-shift-specific impairments. The results indicate that in this way shift-specific components of health impairment can be separated from other non-shift related components.     

12-h workdays: current knowledge and future directions

Work schedules other than those based on the traditional 8-h workday duration have become much more common in recent years. Many such schedules compress the work week into three or four longer workdays and include an increased number of days off. In particular, rosters based on 12-h workdays have gained in popularity, and such rosters have been the focus of considerable research. The literature on 12-h workdays is, however, full of inconsistencies. Not surprisingly, there is considerable evidence from some of these studies that 12-h shifts tend to cause more fatigue than 8-h shifts. This extra fatigue may be associated with lower work efficiency, and with more errors and accidents. There is also strong evidence that workers prefer 12-h shifts due to some perceived advantages. The present paper reviews and examines these studies and their findings and discusses some possible reasons for the apparent contradictions in reported findings. Directions for decision makers and future research are suggested.     

Demanding work schedules and mental health in nursing assistants working in nursing homes

Nursing home assistants have physically and emotionally challenging jobs, and they often work demanding schedules in order to provide 24-h care. While the physical effects of demanding work schedules have been studied, little is known about the impact on mental health. This study explored the relationship between demanding scheduling variables and mental health indicators of depression, anxiety and somatization. A cross-section of 473 US female nursing assistants working in nursing homes was surveyed. Work schedule characteristics included shiftwork, hours per day and week, days per week, number of weekends per month, number of double shifts per month, breaks, and number of jobs worked. Working two or more double-shifts per month was associated with increased risk for all mental health indicators, and working 6–7 days per week was associated with depression and somatization. There was a trend for increasing odds of adverse mental health with increased numbers of demanding work schedule factors. The odds of depression was increased four-fold when working 50+ h/week, more than two weekends/month and more than two double shifts/month. Providing work schedules that are less unhealthy may have implications for both worker retention and the quality of care delivered to nursing home residents.     

Associations between stress at work and attitudes towards retirement in hospital physicians

Abstract

There is a need to understand the associations between attitudes towards retirement in specific occupations and various psychosocial and work-related factors. This study identified correlates of retirement thoughts and retirement preference in hospital physicians. The sample comprised 447 (251 male and 196 female) physicians from three hospital districts in Finland. After adjustment for gender, age and salary, minor psychiatric morbidity increased likelihood of retirement thoughts and retirement preference. Retirement thoughts and retirement preference were more common in doctors reporting low job control, poor teamwork and unjust supervision than in doctors perceiving their working conditions more favorably. Work preference was associated with high overwork. The associations of work characteristics with retirement thoughts and retirement preference largely persisted after control for indicators of health and social circumstances. In conclusion, in addition to demographic and financial factors and health, retirement attitudes in hospital physicians seem to be related to organizational and managerial factors that are potentially amendable to intervention. This has implications for retaining hospital physicians who might otherwise retire.     

An expanded typology of conflict at work: Task,relationship and non-task organizational conflict as social stressors

This study investigated the roles of three types of conflict at work – task, relationship and non-task organizational – in predicting employee strain. These conflict types refer to disputes over issues that are, respectively, work-task specific, driven by emotionally charged interpersonal animosity or rooted in more broad organizationally relevant issues. Findings from a sample of 260 working adults from various organizations in the United States supported the notion that the three types of conflict function as social stressors and are related to a variety of psychological, behavioural and physical strains. They extend previous research based primarily on relationship conflict. Non-task organizational conflict emerged as a key predictor across strain criteria, thus highlighting the importance of including a more complete conceptualization of the conflict construct in social stress research. The results for task conflict are at variance with findings that it can be beneficial, and suggest that its negative relationship with well-being may be due to its co-occurrence with the other forms of conflict. These findings provide support for an expanded typology of conflict.     

IGLOO: An integrated framework for sustainable return to work in workers with common mental disorders

ABSTRACT

Current research on return to work (RTW) for employees with common mental disorders suffers from two limitations. First, research mostly focuses on the influence of resources during the absence period ignoring the resources which may facilitate sustainable RTW, i.e. employees continuing to work and thrive at work post-return. Second, research tends to view the work and non-work domains separately and fails to consider the interaction of resources at the individual, group, leader and organisational levels, once back at work. In the present position paper, we present an integrated framework and a preliminary definition of sustainable RTW. Based on current occupational health psychology theory and existing research on RTW, we develop ten propositions for the resources in and outside work, which may promote sustainable RTW. In addition to the individual, group, leader, and organisational levels, we also argue for the importance of the overarching context, i.e. the societal context and the culture and legislation that may promote sustainable RTW. Our framework raises new questions that need to be addressed to enhance our understanding of how key stakeholders can support employees with common mental health disorders staying and thriving at work.     

Physical exercise,employee fitness and the management of health at work

Abstract

This paper presents some recent data on why organizations invest in exercise and physical fitness programmes for their stiff. These data suggest that, owing to a lack of evaluation studies, organizations act mainly on the basis of assumption and belief. However, from a subsequent review of the available literature on the personal and organizational effects of such programmes, it appears that these assumptions and beliefs are not altogether unfounded. The paper concludes by discussing the ways in which exercise and employee fitness programmes might help die individual and their organization in terms of the management of health at work.     

Health Risk Characterization of Chlorpyrifos Using Epidemiological Dose‐Response Data and Probabilistic Techniques: A Case Study with Rice Farmers in Vietnam

Various methods for risk characterization have been developed using probabilistic approaches. Data on Vietnamese farmers are available for the comparison of outcomes for risk characterization using different probabilistic methods. This article addresses the health risk characterization of chlorpyrifos using epidemiological dose‐response data and probabilistic techniques obtained from a case study with rice farmers in Vietnam. Urine samples were collected from farmers and analyzed for trichloropyridinol (TCP), which was converted into absorbed daily dose of chlorpyrifos. Adverse health response doses due to chlorpyrifos exposure were collected from epidemiological studies to develop dose‐adverse health response relationships. The health risk of chlorpyrifos was quantified using hazard quotient (HQ), Monte Carlo simulation (MCS), and overall risk probability (ORP) methods. With baseline (prior to pesticide spraying) and lifetime exposure levels (over a lifetime of pesticide spraying events), the HQ ranged from 0.06 to 7.1. The MCS method indicated less than 0.05% of the population would be affected while the ORP method indicated that less than 1.5% of the population would be adversely affected. With postapplication exposure levels, the HQ ranged from 1 to 32.5. The risk calculated by the MCS method was that 29% of the population would be affected, and the risk calculated by ORP method was 33%. The MCS and ORP methods have advantages in risk characterization due to use of the full distribution of data exposure as well as dose response, whereas HQ methods only used the exposure data distribution. These evaluations indicated that single‐event spraying is likely to have adverse effects on Vietnamese rice farmers.     

Individual and situational correlates of motivation for skills upgrading: an empirical study

The present research examines the tenability of a number of factors thought to precede an individual's motivation for skills upgrading. Because motivation for skills upgrading is instrumental to training success and is highly malleable, knowing the factors that precede motivation for skills upgrading would help managers and policy makers a great deal in formulating strategies to raise the competitiveness of the workforce. We derive several testable hypotheses from the existing literature and empirically verify the selected antecedents of motivation for skills upgrading. Results based on responses from 413 employees suggest that an individual's attitude towards skills upgrading, self-efficacy, usefulness of skills upgrading, health condition and long-term orientation are positively related to motivation for skills upgrading. Implications for policy makers, managers and researchers are discussed.     

Improving human resources for health planning in developing economies

There is a universal consensus that human resources represent the heart and soul of effective health systems everywhere. However, despite this consensus, human resource planning in low income countries remains a neglected, often poorly implemented and ineffective component of health-system development. The planning exercises that do take place are often inefficient, use inappropriate planning models or fail to adequately prioritize human resource investment decisions. This article briefly discusses possible reasons why this failure occurs and describes four key steps that can help health system planners more effectively prioritize and link human resource for health investment decisions to health system strategy and programmatic initiatives. Implications for human resource development practice and national human resource development are discussed.
