Work-life imbalance and mental health among male and female employees in Switzerland

Long working hours, work-life imbalance, and poor mental health: a cross-sectional mediation analysis based on the sixth Korean Working Conditions Survey, 2020-2021

Background There has been growing concern about the negative mental health impact of long working hours and overwork. Our study examined how work-life imbalance (WLI) could be a mediator between working hours and poor mental well-being.Methods We included 34,968 individuals from a nationwide cross-sectional survey in Korea. Self-reported working hours per week was collected, and mental health was assessed by the WHO-5 Well-Being Index. Counterfactual-based mediation models were employed to disentangle the total effects into a direct effect (work hour - poor mental health) and an indirect effect (work hour - WLI - poor mental health).Results Out of 34,968 participants, 52.6% worked 35-40 h/week, 20.0% worked 41-48 h/week, 11.7% worked 49-54 h/week, and 15.6% worked ≥55 h/week. The odds ratios (ORs) of the total impact of working hours on poor mental health were 1.08 (95% CI: 1.01-1.16) for 41-48 h/week, 1.28 (1.17-1.39) for 49-54 h/week, and 1.60 (1.48-1.74) for ≥55 h/week in comparison to 35-40 h/week. The ORs of the indirect effects were 1.04 (1.03-1.05) for 41-48 h/week, 1.08 (1.07-1.09) for 49-54 h/week, and 1.14 (1.12-1.16) for ≥55 h/week, accounting for 51%, 31%, and 28% of the total effects.Conclusion: Our findings suggest that WLI can partially mediate the association of long working hours with mental health deterioration. Policy efforts are required to mitigate the adverse mental health effects of overwork.

Work and Family Conflicts, Depression, and "Ikigai": A Mediation Analysis in a Cross-cultural Study Between Japanese and Egyptian Civil Workers

BACKGROUND

Total work-family conflicts (TWFCs) could associate with mental health, and having ikigai (a purpose of life) may mediate this association.

METHODS

In a cross-cultural study of 4,792 Japanese Aichi Workers' Cohort study participants and 3,109 Egyptian civil workers, the Midlife Development in the United States (MIDUS) questionnaire measured TWFCs and the Center for Epidemiological Studies Depression (CES-D) 11-item scale measured depression. We used logistic regression models to estimate odds ratios (ORs) of having depression and a high-ikigai across levels of TWFCs (low, moderate, and high), and the PROCESS macro of Hayes to test the mediation effect.

RESULTS

The prevalence of high TWFCs, depression, and having a high ikigai were 17.9%, 39.4%, and 70.1% in Japanese women, 10.5%, 26.8%, and 70.1% in Japanese men, 23.7%, 58.2%, and 24.7% in Egyptian women, and 19.1%, 38.9%, and 36.9% in Egyptian men, respectively. Compared with participants with low TWFCs, the multivariable ORs of depression in Japanese women and men with high TWFCs were 4.11 (95% confidence interval [CI], 2.99-5.65) and 5.42 (95% CI, 4.18-7.02), and those in Egyptian women and men were 4.43 (95% CI, 3.30-5.95) and 4.79 (95% CI, 3.53-6.48), respectively. The respective ORs of having a high-ikigai were 0.46 (95% CI, 0.33-0.64) and 0.40 (95% CI, 0.31-0.52) in Japanese women and men and were 0.34 (95% CI, 0.24-0.48) and 0.28 (95% CI, 0.20-0.39) in Egyptian women and men. No interaction between TWFCs and country was observed for the associations with depression or ikigai. Ikigai mediated (up to 18%) the associations between the TWFCs and depression, especially in Egyptian civil workers.

CONCLUSION

TWFCs were associated with depression, and having low ikigai mediated these associations in Japanese and Egyptian civil workers.

Where is the limit for overtime? Impacts of overtime on employees' mental health and potential solutions: A qualitative study in China

Although Labor Law of the People's Republic of China stipulates the overtime system, overtime is still widespread in the IT industry. Through qualitative interviews, we explored the impact of overtime on employees' mental health and life. The current study identified four main themes, namely overtime reasons, outcomes of overtime, influential factors and solutions to overtime challenges. Besides work-related reasons and cultural influence, it was found that employees may work overtime due to personal reasons, such as capability and personal qualities; the most frequent impacts reported were fatigue, depression, stress and interference with life; three predominant influential factors were timing of overtime, control and rewards; and overtime conditions could be improved in practical and emotional ways. The study's findings highlight the importance of the design of flexible working time arrangements for avoiding fatigue and improving employees' work-life balance, enhancement of schedule arrangement for avoiding daily work interruption and last-minute tasks, and optimization of rewarding systems for avoiding complaints and facilitating voluntary overtime. Results suggest that mental health and work-life balance can be promoted by organizational initiatives focusing on minimizing excessive job demands, increasing psychosocial resources, supporting boundary management, and enhancing perceived flexibility.

Is Working from Home a Blessing or a Burden? Home Demands as a Mediator of the Relationship Between Work Engagement and Work-Life Balance

As COVID-19 pandemic made its incursion into the world of work in early 2020, many employees were compelled to work from home to slow down the transmission of the disease. Since then, it has been asked whether working from home is a blessing or a burden. We respond to this question by building on the Affective Events Theory to examine whether work engagement is related to work-life balance (WLB), and whether home demands mediate this relationship, using data from 219 knowledge workers drawn from universities in the South-eastern region of Nigeria primarily working from home when they were surveyed. Results of regression analysis using PROCESS macro showed that work engagement related positively to home demands; in turn, home demands related negatively to WLB. The results further revealed that work engagement related negatively to WLB and that home demands mediated the negative work engagement-WLB connection. Theoretical as well as practical implications of the study are discussed, limitations are highlighted, and suggestions for future research are outlined.

The magnitude and effect of work-life imbalance on cognition and affective range among the non-western population: A study from Muscat

The temporal relationship between work-life balance/imbalance, occupational burnout, and poor mental health outcomes have been widely explored. Little has been forthcoming on cognitive functioning among those with work-life imbalance. This study aimed to explore the rate of work-life imbalance and the variation in neuropsychological functioning. The relationship between affective ranges (anxiety and depressive symptoms) and work-life balance was also explored. The target population in this study are Omani nationals who were referred for psychometric evaluation. The study employs neuropsychology measures tapping into attention and concentration, learning and remembering, processing speed, and executive functioning. Subjective measures of cognitive decline and affective ranges were also explored. A total of 168 subjects (75.3% of the responders) were considered to be at a work-life imbalance. Multivariate analysis showed that demographic and neuropsychological variables were significant risk factors for work-life imbalance including age and the presence of anxiety disorder. Furthermore, participants indicating work-life imbalance were more likely to report cognitive decline on indices of attention, concentration, learning, and remembering. This study reveals that individuals with work-life imbalance might dent the integrity of cognition including attention and concentration, learning and remembering, executive functioning, and endorsed case-ness for anxiety.

Work-Life Balance and Mental Health Needs of Health Professionals During COVID-19 Pandemic in Turkey

Health professionals constitute a group that is at a high risk of COVID-19. They have been found to experience difficulties in many issues, one of which is that they face the risk of infecting themselves and others due to interaction with high-risk patients. The present study investigates how demographical and individual factors and work addiction affected work-life balance and mental health needs of health professionals. The data of the present study were collected in the first wave of pandemic. The hypothesized structural equation model was rejected based on the fit indices. The second analysis of modified model was significant and indicated that whether health professionals live alone or with others such as family members had direct effects on work addiction, indirect effects on work-life balance, and needs for mental health. In addition, gender and working hours had direct effects on work-life balance. The highest effect on work-life balance was caused by work addiction. Moreover, work addiction had a moderate effect on mental health needs. As a result, the current study showed that work-life balance, work addiction, and the need for mental health were affected during the COVID-19 pandemic.

Sleep Duration Moderates the Relationship Between Perceived Work-Life Interference and Depressive Symptoms in Australian Men and Women from the North West Adelaide Health Study

BACKGROUND

Mental health disorders are prevalent and costly to workplaces and individuals in Australia. Work-life interference is thought to contribute negatively. The interplay between work-life interference, depressive symptoms and sleep has not been explored to date in population data. The aims of this study were to establish whether sleep duration moderates the relationship between work-life interference and depressive symptoms, and whether this is expressed differentially in male and female respondents.

METHODS

Data were drawn from the North West Adelaide Health Study (NWAHS) longitudinal, representative population-based cohort study. Working members of the cohort were invited to participate in a telephone survey about their work conditions, with an 86.7% response rate achieved. Data from 823 respondents were analysed after employing purposeful selection of covariates, using multivariable regression analysis.

RESULTS

Sleep duration was found to moderate the relationship between work-life interference and depressive symptoms (F_7,815 = 26.60, p < 0.001), and accounted for 19% of the variance observed in depressive symptoms. The strongest effect of work-life interference on depressive symptoms was observed in habitual short sleepers, with the effect weakening as sleep duration increased. The relationship was observed in male and female respondents, but was stronger in females.

CONCLUSIONS

Supporting and educating workers about the benefits of sleep for managing the relationship between work-life interference and depressive symptoms may offer a novel strategy for improving worker well-being, particularly when negative facets of work-life interference are not easily remedied or 'reduced'. There is a need for education and support strategies around sleep in Australian workplaces.

Employment adjustment and mental health of employed family caregivers in Canada

Family caregivers make employment adjustment to fulfill caregiving responsibility. However, the studies on the family caregivers' mental health outcomes associated with their employment adjustment are limited. This study utilized the role theory and stress process model of caregiving to examine the relationship between employment adjustment and mental health outcomes among family caregivers, and to test family-to-work role conflict as a mediator and workplace support as a moderator in this relationship. Data (n = 1,696) were drawn from the 2012 Canada General Social Survey: Caregiving and Care Receiving. Findings suggest that employment adjustment is significantly associated with negative mental health outcomes including worse self-rated mental health and higher life stress level. In addition, family-to-work role conflict mediates between employment adjustment and mental health outcomes, with the mediating effect as significant at all levels of workplace support and as weak with increasing workplace support. The findings highlight the role of family-to-work role conflict in understanding the influence of employment adjustment on family caregiver's mental health, and the implication of workplace support on promoting caregiver-friendly workplace culture to alleviate family-to-work role conflict thereby resulting in better mental health outcomes.

The health effects of work-family conflict in men and women Japanese civil servants: a longitudinal study

High level of work-family conflict (WFC) is an important risk factor for stress-related health outcomes. However, many studies are cross-sectional studies. In this study, we aimed to clarify how changes in WFC levels over a period 5 yr can affect workers' mental and physical health, and to clarify whether there are gender differences of them. This study examined 1,808 civil servants (1,258 men and 550 women) aged 20-65 yr working in a local government in the west coast of Japan from 2003 to 2008. Logistic regression analyses were used to examine whether the change in WFC contributes to workers' health problems and whether there are gender differences. This study revealed association sustained high WFC and deterioration of WFC conflict with poor mental health and poor job satisfaction for both men and women. In men high WFC conflict and deterioration was associated with poor mental health (OR=2.74). On the other hand, women had strong relationship between WFC changes and poor physical health (OR=2.64). WFC was an important factor as a social determinant of health of Japanese civil servants, and the change in WFC affects subsequent health problems with different trends in men and women.

Socioeconomic status, work-life conflict, and mental health

BACKGROUND

Work-life conflict (WLC) has a critical effect on employee mental health. However, research on occupational health has neglected the family domain. Furthermore, although it is reasonable to assume that the effect of WLC on health may differ according to socioeconomic circumstances, there is little empirical evidence for differences in the impact of WLC by socioeconomic status (SES). The purpose of this study was to assess the role of SES as an effect modifier, while examining whether the SES level affects the relationship between WLC and mental health.

METHOD

We analyzed data from the nationally representative South Korean Working Conditions Survey of 2014, including 49 401 workers. Logistic regression analyses, stratified by sexes, were performed to identify sex differences, and interaction terms including WLC and SES were also incorporated.

RESULTS

WLC (men: OR = 1.24; women: OR = 1.18) and domestic demands (men: OR = 1.16; women: OR = 1.22) were significantly associated with mental health. WLC exhibited a stronger association with mental health for individuals with high SES, both in terms of education (men: OR = 1.61 vs 1.51; women: OR = 1.52 vs 1.24) and income (men: OR = 1.44 vs 1.10; women: OR = 1.48 vs 1.20).

CONCLUSIONS

Our data suggest that future efforts for health promotion should consider workers' family demands and SES as important modifying factors of psychological health in the workplace.

Work-life balance and self-reported health among working adults in Europe: a gender and welfare state regime comparative analysis

Background

The pressing demands of work over the years have had a significant constraint on the family and social life of working adults. Moreover, failure to achieve a ‘balance’ between these domains of life may have an adverse effect on their health. This study investigated the relationship between work-life conflict and self-reported health among working adults in contemporary welfare countries in Europe.

Methods

Data from the 6th European Working Conditions Survey 2015 on 32,275 working adults from 30 countries in Europe were analysed. Multivariate logistic regression models were used to examine the associations between work-life balance and self-reported health among men and women. We further used a 2 stage multi-level logistic regression to assess variations in self-reported health among welfare state regimes by gender.

Results

The results showed a strong association between work-life conflict and poor self-reported health among working adults in Europe (aOR = 2.07; 95% CI: 1.93–2.23). However, the magnitude of the effect differed slightly by gender (men: aOR = 1.97; 95% CI: 1.78–2.18 vs women: aOR = 2.23; 95% CI: 2.01–2.47). Furthermore, we found variations in the relationship between work-life conflict and poor self-reported health between welfare states regimes. The association was found to be weaker in the Nordic and Southern welfare states than the Liberal, Conservative, and Central Eastern European welfare states. Although the associations were more consistent among men than women in the Conservative welfare states regime, we found higher associations for women than men in the Southern, Nordic, Liberal, and Central Eastern European welfare states.

Conclusions

This study provides evidence of some variations in the association between work-life conflict and poor self-reported health among men and women across welfare states regimes in Europe. The results demonstrate the need for governments, organizations and policymakers to provide conducive working conditions and social policies for working adults to deal with competing demands from work and family activities.

Association of work-life balance with occupational injury and work-related musculoskeletal pain among Korean workers

Background

The concept of work-life balance (WLB) has become an important issue in workers' health and safety. This study aims to investigate the relationship between WLB and occupational injury and work-related musculoskeletal pain.

Method

The study included 27,383 workers who participated in the Fifth Korean Working Conditions Survey. Participants were divided into good WLB and poor WLB groups based on their responses to the five question items which comprised two dimensions: work-on-life conflict (items, 1–3) and life-on-work conflict (items 4 and 5). Occupational injury and musculoskeletal pain were also assessed using the question items. The χ² test and multivariate logistic regression analyses were performed to examine the relationship of WLB to occupational injury and musculoskeletal pain while considering socio-demographic and occupational characteristics and ergonomic and psychological risk factors.

Results

Of the 27,383 participants, 252 (0.9%) had experienced an occupational injury and 6,408 (23.4%) had musculoskeletal pain. The poor WLB group had higher injury rates for both men (1.7%) and women (0.9%) than the good WLB group (1.1% and 0.4%, respectively). Additionally, the prevalence of musculoskeletal pain was higher for both men and women in the poor WLB group (25.2% and 28.0%, respectively) than for men and women in the good WLB group (18.7% and 23.6%, respectively). In the logistic regression analysis, the adjusted odds ratio of WLB for occupational injury was 1.37 (95% confidence interval [CI]: 1.06–1.78), and that for musculoskeletal pain was 1.14 (95% CI: 1.07–1.21), showing positive associations of WLB with both occupational injury and musculoskeletal pain.

Conclusions

Poor WLB causes an increase in occupational injury and musculoskeletal pain. Therefore, an improvement in WLB may reduce the incidence of occupational injury and musculoskeletal pain among workers. Social and policy-related initiatives are needed to improve workers' WLB to reduce occupational injury and musculoskeletal pain.

Work-related psychosocial risk factors and psychiatric disorders: A cross-sectional study in the French working population

Purpose

The study estimates the prevalence of probable psychiatric disorder in the working population, determines the proportion of people presenting a probable psychiatric disorder among people exposed to work-related psychosocial risk factors (PSRFs), and identifies which PSRF has the strongest association with having a probable psychiatric disorder.

Methods

A cross-sectional study conducted in March 2018 involved a representative sample of the French working population. The General Health Questionnaire 28 (GHQ-28) was used to estimate the prevalence of probable psychiatric disorder and 44 items were gathered from theoretical models of PSRFs. We used multiple logistic regression to estimate the association of each PSRF with having a probable psychiatric disorder, adjusted on individual, health, and job confounders.

Results

This study involved 3200 French participants. The proportion of probable psychiatric disorder was 22.2% [20.6; 24.0]. Ten PSRFs were significantly associated with it. The strongest association was for having problems handling professional and personal responsibilities (reported by 15% of the study population) (OR = 1.97 [1.52; 2.54]), with 45% pathological GHQ-28 scores (potential psychiatric cases) for people exposed to this PSRF versus 18% non-exposed. The next strongest association was lack of support of colleagues (reported by 28%) (OR = 1.63 [1.29; 2.06]). The third strongest association was feeling sometimes afraid when doing the job (reported by 63%) (OR = 1.53, [1.21; 1.93]).

Conclusions

Our study identified 10 PSRFs associated with psychiatric disorder, with substantial exposure rate among the population. The results of our research could help develop recommendations to improve work environment.

Occupational balance and sleep among women

BACKGROUND

In occupational therapy, while several studies have focussed on occupational balance, few have investigated it in the context of sleep.

AIMS

The aim of this study was to investigate the associations between sleep and occupational balance among women.

MATERIAL AND METHODS

In total, 157 women responded to the Occupational Balance Questionnaire and Karolinska Sleep Questionnaire. Linear regression was used to analyse data.

RESULTS

The median score for occupational balance was 12 (interquartile range [IQR] 9), while that for sleep was 86 (IQR 16). Sleep and sleepiness fatigue were significantly associated (p < 0.1) with satisfaction with the number of occupations during a regular week. Difficulties awakening and snoring disorders were significantly associated (p < 0.1) with balance with physical, social, intellectual, and restful occupations.

CONCLUSIONS

The majority of participants slept well and had a good sleep quality. There is an association between occupational balance and sleep. In particular, aspects related to the number of occupations, adequate time to perform them and the time spent recovering and sleeping were associated with good sleep quality. Balance among physical, social, intellectual, and restful occupations was associated with difficulties awakening and snoring.

SIGNIFICANCE

Our results support the need for occupational therapists to focus on occupational balance, to improve women's sleep.

Postpartum Diet Quality: A Cross-Sectional Analysis from the Australian Longitudinal Study on Women's Health

Reproductive-aged women are at high risk of developing obesity, and diet quality is a potential modifiable risk factor. There is limited research exploring diet quality and its association with time since childbirth. Using data from the Australian Longitudinal Study on Women’s Health (ALSWH) survey 5 (2009) of women born between 1973–1978, who reported having previously given birth, we investigated the association between time since childbirth and diet quality, and differences in energy, macronutrients, micronutrient intake, and diet quality assessed by the dietary guideline index (DGI) in women stratified by time from last childbirth, early (0–6 months; n = 558) and late (7–12 months; n = 547), and all other women with children (>12 months post childbirth n = 3434). From this cohort, 8200 participants were eligible, of which 4539 participants completed a food frequency questionnaire (FFQ) and were included in this analysis. Overall, diet quality was higher in early and late postpartum women (mean DGI score 89.8 (SD 10.5) and mean DGI score 90.0 (SD 10.2), respectively) compared to all other women with children (>12 months post childbirth), mean DGI score 85.2 (SD 11.7), p < 0.001. Factors positively associated with diet quality included higher education, physical activity, health provider support, and vitamin and/or mineral supplement use. Conversely, increasing time from childbirth (>12 months), smoking compared with non-smoking and medium income level compared with no income was negatively associated with diet quality. A lower diet quality in women greater than 12 months post childbirth may be reflective of increased pressures, balancing childrearing and return to work responsibilities. This highlights the need to support women beyond the postpartum period to improve modifiable factors associated with weight gain, including diet quality, to optimize health and reduce chronic disease risk.

Conflicto empleo-familia y autopercepción de la salud desde una perspectiva de género

Resumen El objetivo de este estudio es analizar las desigualdades de género en la relación del conflicto empleo familia (CEF) con el estado de salud de la población trabajadora de Quito y Guayaquil. Se trata de un estudio transversal de una muestra representativa de la población trabajadora no agrícola, con edad igual o mayor a 18 años y afiliada a la seguridad social, que fue entrevistada entre 2016-2017 en la I Encuesta sobre Condiciones de Seguridad y Salud en el Trabajo de Quito y Guayaquil (n=1729). Se emplearon modelos de regresión de Poisson con varianza robusta, separados por sexo, para calcular las razones de prevalencia ajustadas de seis indicadores de salud. En ambos sexos, el CEF se asoció con mala salud autopercibida, mala salud mental, dolor o molestias de cabeza y de espalda, aunque la magnitud de asociación fue mayor en las mujeres. Además, en las mujeres el CEF se asoció con problemas digestivos (RPa=1,65; IC 95%: 1,17-2,34). En ninguno de los dos sexos se observó asociación entre el CEF y los accidentes de trabajo. Los resultados del presente estudio muestran que el CEF se asocia con malas condiciones de salud en la población trabajadora, particularmente en las mujeres. Las políticas públicas e intervenciones en los centros de trabajo dirigidas a alcanzar un equilibrio entre el empleo y la vida familiar desde una perspectiva de género podrían resultar en una reducción en los daños a la salud y en las desigualdades de género en salud.

Prevalence and associated factors of depression and anxiety among doctoral students: the mediating effect of mentoring relationships on the association between research self-efficacy and depression/anxiety

Purpose

Although the mental health status of doctoral students deserves attention, few scholars have paid attention to factors related to their mental health problems. We aimed to investigate the prevalence of depression and anxiety in doctoral students and examine possible associated factors. We further aimed to assess whether mentoring relationships mediate the association between research self-efficacy and depression/anxiety.

Methods

A cross-sectional study was conducted among 325 doctoral students in a medical university. The Patient Health Questionnaire 9 and Generalized Anxiety Disorder 7 scale were used to assess depression and anxiety. The Research Self-Efficacy Scale was used to measure perceived ability to fulfill various research-related activities. The Advisory Working Alliance Inventory-student version was used to assess mentoring relationships. Linear hierarchical regression analyses were performed to determine if any factors were significantly associated with depression and anxiety. Asymptotic and resampling methods were used to examine whether mentoring played a mediating role.

Results

Approximately 23.7% of participants showed signs of depression, and 20.0% showed signs of anxiety. Grade in school was associated with the degree of depression. The frequency of meeting with a mentor, difficulty in doctoral article publication, and difficulty in balancing work–family–doctoral program was associated with both the level of depression and anxiety. Moreover, research self-efficacy and mentoring relationships had negative relationships with levels of depression and anxiety. We also found that mentoring relationships mediated the correlation between research self-efficacy and depression/anxiety.

Conclusion

The findings suggest that educational experts should pay close attention to the mental health of doctoral students. Active strategies and interventions that promote research self-efficacy and mentoring relationships might be beneficial in preventing or reducing depression and anxiety.

Work-Life Conflict among U.S. Long-Haul Truck Drivers: Influences of Work Organization, Perceived Job Stress, Sleep, and Organizational Support

Work-life balance and job stress are critical to health and well-being. Long-haul truck driving (LHTD) is among the unhealthiest and most unsafe occupations in the U.S. Despite these disparities, there are no extant published studies examining the influence of work, stress and sleep outcomes on drivers’ work-life balance. The current study investigated whether adverse work organization, stress, and poor sleep health among LHTDs are significantly associated with work-life conflict. Logistic regression was used to examine how work organization characteristics, job stress, and sleep influenced perceived stress and a composite measure of work-life conflict among a sample of 260 U.S. LHTDs. The pattern of regression results dictated subsequent analyses using structural equation modeling (SEM). Perceived job stress was the only statistically significant predictor for work-life balance. Fast pace of work, sleep duration and sleep quality were predictors of perceived job stress. SEM further elucidated that stress mediates the influences of fast work pace, supervisor/coworker support, and low sleep duration on each of the individual work-life balance indicators. There is an urgent need to address work conditions of LHTDs to better support their health, well-being, and work-life balance. Specifically, the findings from this study illustrate that scheduling practices and sleep outcomes could alleviate job stress and need to be addressed to more effectively support work-life balance. Future research and interventions should focus on policy and systems-level change.

The association between shift work and chronic kidney disease in manual labor workers using data from the Korea National Health and Nutrition Examination Survey (KNHANES 2011-2014)

Objective

Kidneys are organs having a biological clock, and it is well known that the disruption of the circadian rhythm increases the risk of chronic kidney disease (CKD), including the decline of renal and proteinuria. Because shift work causes circadian disruption, it can directly or indirectly affect the incidence of chronic kidney disease. Therefore, the purpose of this study was to investigate the association between shift work and chronic kidney disease using a Korean representative survey dataset.

Methods

This study was comprised of 3504 manual labor workers over 20 years of age from data from the fifth and sixth Korea National Health and Nutrition Examination Survey (2011–2014). The work schedules were classified into two types: day work and shift work. The estimated glomerular filtration rate, which is the ideal marker of renal function, was estimated according to the Chronic Kidney Disease Epidemiology Collaboration creatinine equation, and chronic kidney disease was defined as urinary albumin to a creatinine ratio equal to or high than 30 mg/g and/or estimated glomerular filtration rate lower than 60 mL/min/1.73 m². The cross-tabulation analysis and multivariate logistic regression analysis were performed to confirm the association between shift work and chronic kidney disease stratified by gender.

Results

The risk of CKD showed a significant increase (odds ratio = 2.04, 95% confidence interval = 1.22, 3.41) in the female worker group. The same results were obtained after all confounding variables were adjusted (odds ratio = 2.34, 95% confidence interval = 1.35, 4.07). However, the results of the male worker group were not significant.

Conclusions

In this study using nationally representative surveys, we found that the risk of CKD was higher female workers and shift work. Future prospective cohort studies will be needed to clarify the causal relationship between shift work and CKD.

Contrasted trends in health-related quality of life across gender, age categories and work status in France, 1995–2016: repeated population-based cross-sectional surveys using the SF-36

Background

Interest in monitoring health-related quality of life (HRQoL) in general populations has increased in the past 20 years, reinforced by population ageing and repeated economic crises. This study aims to identify temporal trends in HRQoL in France between 1995 and 2016 and to assess disparities according to demographic and socioeconomic characteristics.

Methods

Data from repeated population-based cross-sectional surveys conducted in 1995, 2003 and 2016 were used. HRQoL was measured using the Medical Outcomes Study 36-item Short Form (SF-36) questionnaire.

Results

A substantial decrease in score was observed between 1995 and 2016 for both genders in almost all subscales of the SF-36, with the largest decrease being in the mental health dimension for men. However, the age group 18–54 years were the most affected with persistent negative or even worsening trends in HRQoL. The largest decreases were among men aged 45–54 years and women aged 35–44 years in most dimensions, and among the age group 18–24 years in vitality. Conversely, an overall improvement was noted among the age group 65–84 years. People in employment were more affected than the unemployed by the decline in several HRQoL dimensions.

Conclusion

A general decline in HRQoL was found between 1995 and 2016 in the French population, but with wide disparities in trends between age groups. Young and especially middle-aged, employed people exhibited persistent negative and worsening trends. Consistent with evidence from traditional mental health morbidity and mortality indicators, our findings raise questions about the potential influence of macro-socioeconomic factors, especially the 2008 crisis; these observations deserve special attention from health policy-makers.

Factors Associated with Maintaining the Mental Health of Employees after the Fukushima Nuclear Disaster: Findings from Companies Located in the Evacuation Area

After the nuclear disaster in Fukushima on 11 March 2011, some businesses were permitted to continue operating even though they were located in the evacuation area designated by the Japanese government. The aim of this study was to examine differences in the mental health status, workplace, living environment, and lifestyle of employees in the evacuation and non-evacuation areas. We also investigated factors related to their mental health status. Data for this cross-sectional study were collected from the questionnaire responses of 647 employees at three medium-sized manufacturing companies in the evacuation and non-evacuation areas. Through a cross-tabulation analysis, employees who worked at companies in the evacuation areas showed an increase in the duration of overtime work, work burden, and commute time, and had experienced separation from family members due to the radiation disaster and perceived radiation risks. The results of a multivariate logistic regression analysis showed that, even in a harsh workplace and living environment, being younger, participating regularly in physical activity, having a social network (Lubben Social Network Scale-6 ≤ 12), laughing frequently, and feeling satisfied with one's workplace and domestic life were significantly associated with maintaining a healthy mental health status after the disaster. These findings are applicable for workers' health management measures after disasters.

Work, family, and personal characteristics explain occupational and gender differences in work-family conflict among Japanese civil servants

OBJECTIVES

A high level of work-family conflict (WFC) is an important risk factor for physical and mental health problems. Although individual work-related factors for WFC have been extensively studied, relatively little is known about whether occupation and gender affect WFC and how such effects might be generated.

STUDY DESIGN

Cross-sectional study.

METHODS

This study surveyed 3053 civil servants aged 20-65 years working in a local government in the west coast of Japan in 2003. Logistic regression analyses were used to examine whether there are occupational and gender differences in WFC and to clarify the factors underlying these differences.

RESULTS

WFC was higher in professional and technical workers compared with other occupations for both men and women, with age-adjusted odds ratios (ORs) for these workers of 1.29 in men and 2.58 in women. In men, occupational differences in WFC disappeared after adjusting for work and family characteristics (OR = 1.15). In women, significant occupational differences remained in the final model, but after adjusting for work characteristics the adjusted OR for professional and technical workers was reduced to 1.69. Women were more likely than men to experience high WFC (OR = 2.52). After controlling for work characteristics, the gender difference was considerably reduced (OR = 1.68).

CONCLUSIONS

Work characteristics play a fundamental role in the difference in WFC between not only occupational but also gender differences. Stressful work characteristics among professional and technical workers and among women in all work roles should be addressed to reduce occupational and gender differences in WFC in Japan.

Work-Family Conflict and Self-Rated Health: the Role of Gender and Educational Level. Baseline Data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

Purpose

This study examined gender differences in the association between work–family conflict and self-rated health and evaluated the effect of educational attainment.

Method

We used baseline data from ELSA-Brasil, a cohort study of civil servants from six Brazilian state capitals. Our samples included 12,017 active workers aged 34–72 years. Work–family conflict was measured by four indicators measuring effects of work on family, effects of family in work and lack of time for leisure and personal care.

Results

Women experienced more frequent work–family conflict, but in both genders, increased work–family conflict directly correlated with poorer self-rated health. Women’s educational level interacted with three work–family conflict indicators. For time-based effects of work on family, highly educated women had higher odds of suboptimal self-rated health (OR = 1.54; 95 % CI = 1.19–1.99) than less educated women (OR = 1.14; 95 % CI = 0.92–1.42). For strain-based effects of work on family, women with higher and lower education levels had OR = 1.91 (95 % CI 1.48–2.47) and OR = 1.40 (95 % CI 1.12–1.75), respectively. For lack of time for leisure and personal care, women with higher and lower education levels had OR = 2.60 (95 % CI = 1.95–3.47) and OR = 1.11 (95 % CI = 0.90–1.38), respectively.

Conclusion

Women’s education level affects the relationship between work–family conflict and self-rated health. The results may contribute to prevention activities.

Do sleep disturbances mediate the association between work-family conflict and depressive symptoms among nurses? A cross-sectional study

WHAT IS KNOWN ON THE SUBJECT

Nurses are at a high risk for work-family conflict due to long and irregular work hours and multiple physical and psychosocial stressors in their work environment. Nurses report higher rates of depressive symptoms than the general public, leading to a high rate of burnout, absenteeism, and turnover. Work-family conflict is associated with negative consequences in nurses including physical illnesses and mental disorders.

WHAT THIS STUDY ADDS TO EXISTING KNOWLEDGE

Past research on this topic has not examined the mechanisms for the effect of work family conflict on depression. Studies rarely examine the influence of health behaviors such as sleep in explaining this association. Our study identified significant association of sleep disturbances with both work-family conflict and depressive symptoms in nurses. Our main contribution is reporting the important role of sleep disturbances in translating the effect of work-family conflict on depressive symptoms among nurses.

WHAT ARE THE IMPLICATIONS FOR PRACTICE

Nurses need to receive training in best practices for maintaining their own sleep and mental health. Organizations should include sleep health education and training in workplace health programs. Evidence-based interventions to promote healthy sleep practices such as cognitive behavioral therapy and complementary and integrative approaches should be evaluated for their effectiveness in addressing the impact of work-family conflict on the mental health of nurses. Healthcare organizations should incorporate mental health services as part of their Employee Assistance Program for nurses and include psychological and sleep disorders screening, counseling, and follow-up.

ABSTRACT

Introduction Depression has been identified as the leading cause of disability worldwide. Nurses report higher rates of depression than the general public. Work-family conflict is challenging for nurses and may lead to depression and poor health. However, the mechanisms for the effect of work-family conflict on depression have not been well understood. Aim The objective is to use a cross-sectional design to examine the role of sleep disturbances in the association between work-family conflict and depressive symptoms in nurses. Methods Questionnaires, measuring working conditions, work-family conflict, sleep disturbances and depressive symptoms were collected from 397 nurses at a not-for-profit community hospital in the north-eastern United States. Results We observed a significant association between work-family conflict and depressive symptoms (β = 2.22, p < .001) among nurses. Sleep disturbances partially mediated this association by 40.54%. Discussion Sleep disturbances play an important role in translating work-family conflict into depressive symptoms. Implications Evidence-based interventions to promote healthy sleep practices should be evaluated for their effectiveness in addressing the impact of work-family conflict on mental health. Organizations should include sleep education and training as a component of workplace health promotion and employee assistance programmes to mitigate the effect of work-family conflict and promote overall health in nurses.

Temporal change to self-rated health in the Swiss population from 1997 to 2012: the roles of age, gender, and education

OBJECTIVES

Our study aimed to describe the temporal changes in self-rated health status (SRH) from 1997 to 2012 in adults aged 25 to 84 residing in Switzerland, with a view to identifying groups at risk for declining health.

STUDY DESIGN

Secondary analysis of population-based cross-sectional health surveys.

METHODS

Data were collected from the cross-sectional, population-based, five-year Swiss Health Survey, from 1997, 2002, 2007 and 2012. A total of 63,861 individuals' data were included. Multilevel mixed-effect logistic regression analysis was employed to estimate the probability of very good and good health within the framework of a hierarchical cross-classified age-period-cohort model (HAPC), adjusting for education level, gender, civil status, smoking status and body mass index.

RESULTS

Individuals with higher education were substantially more likely than those with primary education to report good SRH (OR = 2.12; 95% CI = 1.93-2.33 for secondary education and OR = 3.79; 95% CI = 3.39-4.23 for tertiary education). The education effect depended on birth cohort and age: higher proportions of good SRH were reported by secondary (8%-17%) and tertiary (10%-22%) compared with primary educated individuals from the 1940 birth cohort onward; the proportion of secondary/tertiary (compared to primary) educated people reporting good SRH increased with age (by 10/11% at 45-50 years and 25/36% at 80-84 years). Gender health equality was achieved by the 1955 (primary educated) and 1960 (secondary educated) birth cohorts, while these women overtook men in reporting good SRH from the 1975 birth cohort onward. Tertiary educated younger women were significantly less likely to report good SRH than men but parity was achieved at around pension age. Similarly, gender inequality in those with primary and secondary education reduced in the younger ages to not be significant at around age 55, with women overtaking men from age 65.

CONCLUSIONS

Younger birth cohorts with lower education levels appear most vulnerable in terms of their SRH. The education effect cumulatively increases when attaining incrementally higher education levels. While women report lower health than men, gender inequality in SRH has declined and even reversed over time and is substantially linked to differences in educational status. Swiss public health strategies should particularly target the younger adults with only primary school education of both genders; for women, to combat health burdens in their early life, and men, to mitigate issues in their later life.

Examining the mediating effect of work-to-family conflict on the associations between job stressors and employee psychological distress: a prospective cohort study

OBJECTIVES

The mediating effect of work-to-family conflict (WFC) on the associations between eight types of job stressors (measured based on the job demands-control, effort-reward imbalance and organisational justice models) and psychological distress in employees was examined.

DESIGN

This study employed a prospective design.

SETTING

An occupational cohort study in Japan (Japanese Study of Health, Occupation, and Psychosocial Factors Related Equity; J-HOPE).

PARTICIPANTS

5859 men and 1560 women who were working for 11 firms and participated at three consecutive waves of J-HOPE, at 1-year intervals, from 2010 to 2013.

MAIN OUTCOME MEASURES

Psychological distress, as measured by Kessler 6 scores.

RESULTS

Mediation analysis using data on job stressors at baseline, WFC at 1-year follow-up and psychological distress at 2-year follow-up showed that WFC mediated 39.1% (95% CI 29.1% to 49.1%) and 44.5% (95% CI 31.4% to 51.7%) of the associations of psychological distress with job demands and effort, respectively, for men. The mediating effect of WFC was smaller for job stressors indicating reduced job resources, compared with job demands and effort. The mediating effect of WFC was somewhat larger for women than it was for men, with WFC mediating 47.5% (95% CI 22.5% to 72.6%) and 64.0% (95% CI 24.3% to 100.0%) of the associations of psychological distress with job demands and effort, respectively.

CONCLUSIONS

WFC was a key mediator in the associations between most job stressors and employee psychological distress. Results suggest that policy measures and support from supervisors, to prevent job stressors from adding to WFC, are needed to reduce employee psychological distress.

Work-Family Conflict, Sleep, and Mental Health of Nursing Assistants Working in Nursing Homes

Work-family conflict is challenging for workers and may lead to depression, anxiety, and overall poor health. Sleep plays an important role in the maintenance of mental health; however, the role of sleep in the association between work-family conflict and mental health is not well-studied. Questionnaires were collected from 650 nursing assistants in 15 nursing homes. Multivariate linear regression modeling demonstrated that increased work-family conflict was associated with lower mental health scores (β = -2.56, p < .01). More work-family conflict was correlated with more job demands, less job control, less social support, and longer work hours. Poor sleep quality, but not short sleep duration, mediated the association between work-family conflict and mental health. Workplace interventions to improve nursing assistants' mental health should increase their control over work schedules and responsibilities, provide support to meet their work and family needs, and address healthy sleep practices.

Occupational Psychosocial Hazards Among the Emerging US Green Collar Workforce

OBJECTIVE

To compare occupational psychosocial hazards in green collar versus non-green collar workers.

METHODS

Standard Occupational Classification codes were used to link the 2010 National Health Interview Survey to the 2010 Occupational Information Network Database. Multivariable logistic regressions were used to predict job insecurity, work life imbalance, and workplace harassment in green versus non-green collar workers.

RESULTS

Most participants were white, non-Hispanic, 25 to 64 years of age, and obtained greater than a high school education. The majority of workers reported no job insecurity, work life imbalance, or workplace harassment. Relative to non-green collar workers (n = 12,217), green collar workers (n = 2,588) were more likely to report job insecurity (Odds ratio [OR] = 1.13; 95% confidence interval [CI] = 1.02 to 1.26) and work life imbalance (1.19; 1.05 to 1.35), but less likely to experience workplace harassment (0.77; 0.62 to 0.95).

CONCLUSIONS

Continuous surveillance of occupational psychosocial hazards is recommended in this rapidly emerging workforce.

Work-family conflict, lack of time for personal care and leisure, and job strain in migraine: Results of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

BACKGROUND

Work-family conflict and time scarcity may affect health. We investigated the association between these issues and migraine, taking into account job strain.

METHODS

Baseline data from ELSA-Brasil (6,183 women; 5,664 men) included four indicators of work-family conflict: time- and strain-based interference of work with family (TB-WFC, SB-WFC), interference of family with work (FWC) and lack of time for personal care and leisure (LOT). Migraine was classified according to International Headache Society criteria.

RESULTS

Among women, definite migraine was associated with SB-WFC (odds ratio [OR] = 1.28; 95% confidence interval [CI] 1.06-1.55), FWC (OR = 1.32; 1.00-1.75), and LOT (OR = 1.30; 1.08-1.58). Probable migraine was associated with SB-WFC (OR = 1.17; 1.00-1.36). High psychological job demands and low social support interacted with LOT in association with definite migraine. Among men, probable migraine was associated with LOT (OR = 1.34; 1.09-1.64), and there were interactions between job strain and WFC for probable migraine.

CONCLUSIONS

Balancing the demands of professional and domestic spheres could be highly relevant in the management of migraines. Am. J. Ind. Med. 59:987-1000, 2016. © 2016 Wiley Periodicals, Inc.

Mediating pathways and gender differences between shift work and subjective cognitive function

OBJECTIVES

Increased injury risk among shift workers is often attributed to cognitive function deficits that come about as a result of sleep disruptions. However, little is known about the intermediate influences of other factors (eg, work stress, health) which may affect this relationship. In addition, gender differences in these the complex relationships have not been fully explored. The purpose of this study is to (1) identify the extent to which work and non-work factors mediate the relationship between shift work, sleep and subsequent subjective cognitive function; and (2) determine if the mediating pathways differ for men and women.

METHODS

Data from the 2010 National Population Health Survey was used to create a cross-sectional sample of 4255 employed Canadians. Using path modelling, we examined the direct and indirect relationships between shift work, sleep duration, sleep quality and subjective cognitive function. Multigroup analyses tested for significantly different pathways between men and women. Potential confounding effects of age and self-reported health and potential mediating effects of work stress were simultaneously examined.

RESULTS

Work stress and sleep quality significantly mediated the effects of shift work on cognition. Age and health confounded the relationship between sleep quality and subjective cognition. No differences were found between men and women.

CONCLUSIONS

Occupational health and safety programmes are needed to address stress and health factors, in addition to sleep hygiene, to effectively address cognitive function among shift workers.

Working Conditions and Mental Health of Nursing Staff in Nursing Homes

Nursing staff in nursing homes suffer from poor mental health, probably associated with stressful working conditions. Working conditions may distribute differently among nursing assistants, licensed practical nurses, and registered nurses due to their different levels in the organizational hierarchy. The objectives of this study were to evaluate the association between working conditions and mental health among different nursing groups, and examine the potential moderating effect of job group on this association. Self-administered questionnaires were collected with 1,129 nursing staff in 15 for-profit non-unionized nursing homes. Working conditions included both physical and psychosocial domains. Multivariate linear regression modeling found that mental health was associated with different working conditions in different nursing groups: physical safety (β = 2.37, p < 0.05) and work-family conflict (β = -2.44, p < 0.01) in NAs; work-family conflict (β = -4.17, p < 0.01) in LPNs; and physical demands (β = 10.54, p < 0.05) in RNs. Job group did not moderate the association between working conditions and mental health. Future workplace interventions to improve mental health should reach to nursing staff at different levels and consider tailored working condition interventions in different nursing groups.

Work-Recreation Balance, Health-Promoting Lifestyles and Suboptimal Health Status in Southern China: A Cross-Sectional Study

Suboptimal health status (SHS)—an intermediate state between health and illness—refers to functional somatic symptoms that are medically undiagnosed. Although SHS has become a great challenge for global public health, very little about its etiology and mechanisms are known. Work-recreation balance is a part of work−life balance, and is related to stress which greatly influences health status. We therefore carried out a cross-sectional investigation between 2012 and 2013 within a clustered sample of 24,475 individuals aged 15−60 years from a population in southern China. In so doing, we hoped to illuminate the associations between work-recreation balance conditions, healthy lifestyles, and SHS. Work-recreation balance conditions were categorically defined by frequency (“rarely, sometimes, or always”). Health-Promoting Lifestyle Profile (HPLP-II) was used to evaluate the level of healthy lifestyles, and the medical examination report and Sub-Health Measurement Scale V1.0 (SHMS V1.0) were both used to evaluate health status. The ratio of SHS (46.3%) is higher than health status (18.4%) or disease status (35.3%). Overall, 4.9% of respondents reported the lowest level of work-recreation balance, and they scored lower on both the HPLP-II and SHMS V1.0 compared with those who frequently maintained a work-recreation balance. Significant association was found between work-recreation balance behaviors and healthy lifestyles (p < 0.001) after demographic adjustment. In comparison with those reporting a frequent work-recreation balance, individuals whose work-recreation balance was categorically “rare” were 1.69 times as likely to develop SHS (odds ratio (OR): 1.69, 95% confidence interval (CI): 1.49–1.92), and those with infrequent work-recreation balance (“sometimes”) were 1.71 times more likely to develop SHS (OR: 1.71, 95% CI: 1.62–1.81). These findings suggest that work-recreation balance conditions are significantly associated with, and seem to be accurate behavioral indicia of a healthy lifestyle. Poor work-recreation balance is associated with increased risk for SHS; thus, a healthier lifestyle that maintains a work-recreation balance should be promoted in order to reduce the development of SHS or disease in southern China.

The experience of work-life balance across family-life stages in Switzerland: a cross-sectional questionnaire-based study

Background

The division of paid and unpaid labor in families continues to be highly gendered with men doing more paid work and women doing more unpaid care work. This is especially true for life stages with young children. Our study investigates the subjective experience of demands in the work and the private domain and the experience of work-life balance across family-life stages as a consequence of this gendered division of labor.

Methods

We used data from a survey study on work-life issues and health in four large companies in Switzerland (N = 3664).

Results

In line with our hypotheses, subjective work and private demands were predicted by an interaction of family-life stages and gender. Specifically, during the primary child-rearing family-life stages, women experience more private demands than men while men experience more work demands, regardless of level of employment. Furthermore, women who work part time experience more work-life balance than women who work full time and more than men who work part or full time during the primary child-rearing family-life stages.

Conclusions

Results are discussed in terms of a gendered work-life experience across the life course and the need for part-time work for both genders. Finally, conclusions are drawn concerning our results’ implications for public health considerations.

Working hours and mental health in Australia: evidence from an Australian population-based cohort, 2001-2012

OBJECTIVES

This paper assesses the impact of working less than or more than standard full-time hours on mental health, as well as possible differences in this relationship by gender and skill level.

METHODS

The study design was a longitudinal cohort with 12 annual waves of data collection over the period 2001-2012, yielding a sample of 90,637 observations from 18,420 people. Fixed effects within-person regression was used to control for time invariant confounding. The Mental Component Summary of the Short Form 36 (SF-36) measure was used as the primary outcome measure. Working hours over the preceding year was measured in five categories with standard full-time hours (35-40 h/week) as the reference.

RESULTS

Results indicated that when respondents were working 49-59 h (-0.52, 95% CI -0.74 to -0.29, p<0.001) and 60 h or more (-0.47, 95% CI -0.77 to -0.16, p=0.003) they had worse mental health than when they were working 35-40 h/week (reference). The difference in mental health when working 49-59 h was greater for women than for men. There were greater declines in mental health in relation to longer working hours among persons in higher compared to lower occupational skill levels.

CONCLUSIONS

Study results suggest the need for employers and governments to regulate working hours to reduce the burden of mental ill health in the working population.

A work-life perspective on sleep and fatigue--looking beyond shift workers

This study examines sleep and fatigue through a work-life lens. Whilst most often thought of as an issue for shift workers, this study observed that self-reported insufficient sleep and fatigue were prevalent for workers on standard daytime schedules. Using a representative sample of 573 daytime workers (51.3% men; 70.7% aged 25-54 yr) from one Australian state, it was observed that 26.4% of daytime workers never or rarely get the seven hours of sleep a night that is recommended for good health. Those with parenting responsibilites (29.4%) or working long (45+) hours (37.4%) were most likely to report insufficient sleep. Whereas mothers in full-time work were most likely to report frequent fatigue (42.5%). This study highlights the common experience of insufficient sleep and fatigue in a daytime workforce, with significant implications for health and safety at work and outside of work. Stronger and more effective legislation addressing safe and 'decent' working time is clearly needed, along with greater awareness and acceptance within workplace cultures of the need to support reasonable workloads and working hours.

Prevalence and Health Correlates of Work-Life Conflict among Blue- and White-Collar Workers from Different Economic Sectors

The research on work-life conflict (WLC) is largely neglected in occupational medicine and public health and typically limited to white-collar workers and public servants. This study therefore aims to explore possible differences in the prevalence of WLC and its association with health outcomes between white- and blue-collar workers from different work environments in Switzerland. Cross-sectional survey data collected in 2007 in the service sector and in 2010 in the industrial sector were used for statistical analyses. A subsample of university graduates employed by large service companies (N = 1,170) from the first survey’s population was taken and compared with a subsample of low or unskilled industrial and construction workers with no or only compulsory education (N = 489) from the second survey’s population. The results show almost consistently, and particularly in women, a lower prevalence of time- and strain-based forms and both causal directions of WLC in blue-collar workers. However, associations between different WLC measures and general, physical and mental health outcomes were found to be equally strong or even stronger among blue-collar workers compared to white-collar workers. Low or unskilled industrial and construction workers are less frequently affected by higher degrees of WLC but are then at no lower risk of suffering poor self-rated health or severe backaches and sleep disorders than university graduates working in the service sector with comparable exposure to WLC. In conclusion, it can be stated that WLC turned out to be much less prevalent but equally or even more detrimental to health in blue-collar workers, who therefore need to be considered in future studies.

Embryologists' health: a nationwide online questionnaire

PURPOSE

The present study evaluates health status and its relation with occupational characteristics and with burnout syndrome among embryologists.

METHODS

A cross-sectional design was used to conduct an online self-assessment survey, sent to all members of the Spanish Association of Clinical Embryologists. The questionnaire contained occupational questions and two standard instruments: 'Short Form-12 Health Survey' as a measure of physical (PCS-12) and mental (MCS-12) health and the Maslach Burnout Inventory-General Survey (MBI-GS) to evaluate the degree of burnout.

RESULTS

The PCS-12 obtained for the Spanish embryologists was higher than that for the reference population. However, the total MCS-12 was significantly lower than that observed in non-institutionalised males and females representative of the general Spanish population aged 35-44 years. In the linear regression model, the dependent variable PCS-12 was related indirectly with the variables number of hours worked per week, BMI, back pain, leg pain and visual discomfort. In the linear regression model, the dependent variable MCS-12 was indirectly related to the gender (male reference; female coefficient regression: -3.23), exhaustion and cynicism dimensions of the MBI-GS. A total of 87 (36.3%) embryologists presented a high score on at least one of the MBI-GS dimensions.

CONCLUSION

In this sample of Spanish embryologists, a norm measure (SF-12) showed their physical health to be better than the average for the general population, but that their mental health was poorer. A significant indirect relation was observed between mental health and burnout syndrome. Strategies to reduce occupational stress and problems should form part of the training provided for clinical embryologists.

The influence of job stress, social support and health status on intermittent and chronic sleep disturbance: an 8-year longitudinal analysis

OBJECTIVE

To determine the role of health status and social support in the relationship between job stress and sleep disturbance, for both intermittent and chronic sleep disturbance.

METHODS

A total of 1946 mid-life adults completed three questionnaires spanning an 8-year time frame. Sleep disturbance was assessed at each time point, and participants were classified as experiencing intermittent, chronic or no sleep disturbance across this 8-year period. Independent variables included a range of job stress measures, social support, physical and mental health, and demographic characteristics.

RESULTS

After controlling for physical and mental health, perceived lack of job marketability increased risk of intermittent sleep disturbance (odds ratio (OR)=1.33, p=0.012). No other job stress measures were associated with either intermittent or chronic sleep disturbance after adjusting for years of education, social support, and employment status. Poorer mental and physical health status, although significantly increasing odds for intermittent sleep disturbance, represented a significantly greater increase in the odds for chronic sleep disturbance over and above intermittent disturbance (OR=0.96, p<0.001 for both SF-12 mental and physical health).

CONCLUSION

This population-based cohort study found little evidence that job stress had an independent effect on chronic or intermittent sleep disturbance independent of health, social support, and education. Risk profiles for intermittent and chronic sleep disturbance did not differ with regard to job stress; however, various demographic and social support factors were distinguishing factors. Health status, both physical and mental, also showed a significantly greater impact on chronic sleep disturbance than intermittent sleep disturbance. Karasek's model of job strain had little value in predicting sleep disturbance outcomes.

Gender differences in the relationship between shiftwork and work injury: examining the influence of dependent children

OBJECTIVE

To examine the relationship between shiftwork and work injury among men and women, taking into account the presence of dependent children.

METHODS

An analysis of respondents to the 2009-2010 Multipurpose Household Survey (n = 6927 women and 7340 men). Logistic regression models examined the work injury risk, adjusting for various covariates.

RESULTS

The risk of work injury associated with shiftwork was higher for women than for men. Nevertheless, gender differences were present only among respondents with dependent children. Shiftworking women with children also had a greater risk of work injury than shiftworking women without children.

CONCLUSIONS

This previously noted elevated risk of injury associated with shiftwork among women compared with that in men may be a product of increased household responsibilities or other factors particular to female shiftworkers with dependent children.

Occupational stress and self-rated health among nurses

OBJECTIVE: To analyze the association between job stress and self-rated health among nurses in public hospital emergency units. METHODS: This is a cross-sectional study undertaken through the administration of a self-administered questionnaire in a sample of 134 health professionals, using the brief version of the Job Stress Scale. Descriptive analyses of the socio-demographic, health and work variables were undertaken, as was multivariate analysis through unconditional logistic regression for adjustment of the association between job stress and poor self-rated health, in accordance with potential confounding variables, with a level of significance of 5%. RESULTS: 70% of the interviewees were classified as passive workers or as with high strain. Poor self-rated health was significantly greater among health professionals with high demand and low control, compared to those with low strain, after adjusting for co-variables. CONCLUSIONS: Low control, allied with low demand, can serve as a demotivating factor, contributing to the increase in professional dissatisfaction. It is recommended that institutions should adopt a policy of planning and managing human resources so as to encourage the participation of health professionals in decision-making, with a view to reducing job stress among nurses.

Association between work-family conflict and musculoskeletal pain among hospital patient care workers

BACKGROUND

A growing body of evidence suggests that work-family conflict is an important risk factor for workers' health and well-being. The goal of this study is to examine association between work-family conflict and musculoskeletal pain among hospital patient care workers.

METHODS

We analyzed a cross-sectional survey of 1,119 hospital patient care workers in 105 units in two urban, academic hospitals. Work-family conflict was measured by 5-item Work-Family Conflict Scale questionnaire. Multilevel logistic regression was applied to examine associations between work-family conflict and self-reported musculoskeletal pain in the past 3 months, adjusting for covariates including work-related psychosocial factors and physical work factors.

RESULTS

In fully adjusted models, high work-family conflict was strongly associated with neck or shoulder pain (OR: 2.34, 95% CI: 1.64-3.34), arm pain (OR: 2.79, 95% CI: 1.64-4.75), lower extremity pain (OR: 2.20, 95% CI: 1.54-3.15) and any musculoskeletal pain (OR: 2.45, 95% CI: 1.56-3.85), and a number of body areas in pain (OR: 2.47, 95% CI: 1.82-3.36) in the past 3 months. The association with low back pain was attenuated and became non-significant after adjusting for covariates.

CONCLUSIONS

Given the consistent associations between work-family conflict and self-reported musculoskeletal pains, the results suggest that work-family conflict could be an important domain for health promotion and workplace policy development among hospital patient care workers.
