Work stressors, drinking with colleagues after work, and job satisfaction among white-collar workers in Japan

Work-health-personal life conflicts in naive patients with chronic hepatitis B receiving initial treatment in China: a qualitative study

OBJECTIVES

People with chronic hepatitis B (CHB) perform sick roles, work roles and personal roles simultaneously. At times, role conflicts arise because of failure to meet the expectations of different roles. Role conflicts may increase dissatisfaction in work and family and impair their physical and mental health. This study aimed to explore the perceptions of role conflicts of treatment-naive patients with CHB in work, personal and sick roles, together with ameliorating factors in the Chinese cultural context.

DESIGN

A qualitative descriptive study. Semistructured interviews were used to collect the experience of work-health-personal life conflicts (WHPLCs), and a brief questionnaire was used to collect demographic and clinical information. SPSS V.21.0 was used for descriptive analysis and Dedoose (V.7.5.9) was used to code and analyse interview transcripts. This study selected six cities with different socioeconomic levels in Zhejiang Province, China. Then, researchers chose one tertiary hospital from each city as the study site, so a total of six tertiary hospitals were involved.

PARTICIPANTS

We recruited 32 patients with CHB (59.38% male) who had just started antiviral therapy for no more than three months. Participants were within the age range of 19-57 years, and the average age was 36.03 (SD=9.56) years.

RESULTS

Participants noted that having CHB influenced their daily life and intersected with work and personal roles, therefore causing role conflicts. Role conflicts focused on three types: time-based conflicts, strain-based conflicts and behaviour-based conflicts. The contextual factors contributing to role conflicts were identified, including personal characteristics, financial strain, traditional social roles and work environment.

CONCLUSIONS

These findings enhance our understanding of the WHPLCs experience of treatment-naive patients with CHB in China. Our findings suggest that multidimensional role conflicts should be taken into account in the intervention design and psychological counselling to improve role balance and well-being among patients with CHB.

Alcohol consumption behaviours in the immediate aftermath of earthquakes: time series study

OBJECTIVES

Earthquakes are a distressing natural phenomenon that can disrupt normal health-related behaviours. The aim of this study was to investigate changes in alcohol consumption behaviours in the immediate aftermath of mild to moderate earthquakes.

SETTING

This retrospective cohort study was conducted at a large academic hospital in Tokyo, Japan from April 2004 to March 2017.

PARTICIPANTS

We included all adult patients presenting with acute alcohol intoxication in the emergency room.

PRIMARY AND SECONDARY OUTCOME MEASURES

Our outcome was the number of such patients per 24 hours period comparing days with and without earthquake activity. We mainly focused on mild to moderate earthquakes (Shindo scale of less than 3). We conducted a simple generalised autoregressive conditional heteroscedasticity (GARCH) analysis, followed by a multivariate GARCH, including year-fixed effects and secular changes in alcohol taxation. Subanalyses were conducted by gender and age group.

RESULTS

During the study period, 706 earthquakes were observed with a median Shindo scale of 2 (IQR: 1). During this period, 6395 patients were admitted with acute ethanol intoxication; the mean age was 42.6 (SD: 16.9) years and 4592 (71.8%) patients were male. In univariate analyses, the occurrence of daytime earthquakes was marginally inversely related to the number of acutely intoxicated patients (β coefficient: -0.19, 95% CI -0.40 to 0.01). This finding remained similar in multivariate analyses after adjustment for covariates. In analyses stratified by gender, the inverse association between daytime earthquakes and alcohol intoxication was only observed among men (p<0.03 for males and p=0.99 for females). In subanalyses by age, older people were less likely to be admitted to the hospital due to acute alcohol intoxication on days with daytime earthquakes (p=0.11), but this was not the case for younger people (p=0.36).

CONCLUSION

On days when a mild to moderate daytime earthquake occurred, the number of patients with acute alcohol intoxication was lower compared with days without earthquakes. Even milder forms of potentially catastrophic events appear to influence social behaviour; mild to moderate earthquake activity is associated with the avoidance of excessive alcohol consumption.

Which work-related characteristics are most strongly associated with common mental disorders? A cross-sectional study

OBJECTIVES

Studies exploring work-related risk factors of common mental disorders (CMDs), such as major depressive disorder (MDD), generalised anxiety disorder (GAD) or alcohol abuse, have generally focused on a limited set of work characteristics. For the first time in a primary care setting, we examine simultaneously multiple work-related risk factors in relation to CMDs.

METHOD

We use data from a study of working individuals recruited among 2027 patients of 121 general practitioners (GPs) representative of the Nord-Pas-de-Calais region in the North of France (April-August 2014). CMDs (MDD; GAD; alcohol abuse) were assessed using the Mini-International Neuropsychiatric Interview. Six worked-related factors were examined (work intensity, emotional demands, autonomy, social relations at work, conflict in values and job insecurity). Several covariates were considered (patient, GP and contextual characteristics). To study the association between workplace risk factors and CMDs, we used multilevel Poisson regression models adjusted for covariates.

RESULTS

Among study participants, 389 (19.1%) met criteria for MDD, 522 (25.8%) for GAD and 196 (9.7%) for alcohol abuse. In multivariable analyses adjusted for covariates, MDD/GAD was significantly associated with work intensity (RR 1.16, 95% CI 1.06 to 1.27) (absolute risk=52.8%), emotional demands (RR 1.24, 95% CI 1.13 to 1.35) (absolute risk=54.9%) and social relations at work (RR 0.78, 95% CI 0.70 to 0.87) (absolute risk=15.0%); alcohol abuse was associated with social relations at work (RR 1.25, 95% CI 1.01 to 1.53) (absolute risk=7.6%) and autonomy (OR 0.82, 95% CI 0.67 to 0.99) (absolute risk=8.9%).

CONCLUSIONS

Several workplace factors are associated with CMDs among working individuals seen by a GP. These findings confirm the role of organisational characteristics of work as a correlate of psychological difficulties above and beyond other sources of risk.

Psychosocial job stress and immunity: a systematic review

The purpose of this review was to provide current knowledge about the possible association between psychosocial job stress and immune parameters in blood, saliva, and urine. Using bibliographic databases (PubMed, PsychINFO, Web of Science, Medline) and the snowball method, 56 studies were found. In general, exposure to psychosocial job stress (high job demands, low job control, high job strain, job dissatisfaction, high effort-reward imbalance, overcommitment, burnout, unemployment, organizational downsizing, economic recession) had a measurable impact on immune parameters (reduced NK cell activity, NK and T cell subsets, CD4+/CD8+ ratio, and increased inflammatory markers). The evidence supports that psychosocial job stresses are related to disrupted immune responses but further research is needed to demonstrate cause-effect relationships.

Is habitual alcohol drinking associated with reduced electrophoretic DNA migration in peripheral blood leukocytes from ALDH2-deficient male Japanese?

Alcohol drinking-derived acetaldehyde is believed to cross-link DNA and induce sister chromatid exchanges in peripheral blood lymphocytes. However, little population data are available to illustrate effects of alcohol-derived acetaldehyde on DNA migration as assayed by the comet assay in peripheral lymphocytes. In the present study, we investigated lifestyle behaviours, including alcohol consumption, in 150 Japanese males by questionnaire, determined their aldehyde dehydrogenase 2 (ALDH2) family genotypes by polymerase chain reaction and measured the DNA migration in peripheral blood leukocytes by the alkaline comet assay. The results showed that habitual alcohol drinking is significantly negatively associated with DNA migration in peripheral blood leukocytes (r = -0.321, P = 0.005) of ALDH2-deficient, but not of ALDH2-proficient genotypes (r = 0.048, P = 0.683). The amount of pure alcohol consumed per time by the subjects showed a similar phenomenon (r = -0.257, P = 0.025 for the ALDH2-deficient, but r = -0.061, P = 0.606 for the ALDH2-proficient genotype). Further stepwise multiple regression analysis showed that alcohol drinking frequency was a significant predictor of DNA migration for subjects with ALDH2-deficient genotype, but not for subjects with ALDH2-proficient genotype. In summary, the present result suggests that frequent alcohol drinking is significantly associated with a reduced electrophoretic DNA migration in peripheral blood leukocytes from ALDH2-deficient male Japanese subjects.

Job strain, effort-reward imbalance, and heavy drinking: a study in 40,851 employees

OBJECTIVE

The objective of this study was to examine the relationship of the job strain model and the effort-reward imbalance model with heavy drinking.

METHODS

Questionnaire survey data were obtained from 32,352 women and 8499 men employed in the Finnish public sector (participation 67%). Logistic regression analyses for all employees and for separate subgroups were undertaken by sex, adjusted for age, education, occupational position, marital status, job contract, smoking, and negative affectivity. Different cutoff points of heavy drinking were used for men and women.

RESULTS

High job strain and high effort-reward imbalance as global constructs were not associated with heavy drinking. However, some components of these models were associated with heavy drinking but the relationships were not all in the expected direction and they varied by sex, age, and occupational position.

CONCLUSIONS

Stressful work conditions are not consistently associated with heavy drinking.

Grouping participants for tailored work-site weight loss programs: a signal detection approach

BACKGROUND

Although work-site obesity prevention programs have been widely promoted, they have a high rate of attrition and participants find it very difficult to maintain the decreased weight. It is necessary to develop effective work-site programs that match the type of intervention to the participants and offer the necessary support. To this end, higher-order interaction of the causal factors of obesity needs to be analyzed.

METHODS

The subjects were male, white-collar workers (20-64 years of age), in Osaka, Japan. Since conventional methods, such as regression analysis or analysis of variance, cannot deal with the interaction of many variables, signal detection analysis by Kraemer was used to identify the higher-order interaction of multiple predictors of obesity.

RESULTS

Out of 15 independent variables, a higher-order interaction consisting of 8 significant variables was identified. Consequently, the subjects were categorized into nine subgroups. It was revealed that the obesity of two groups of workers, 40 or more years old with a high degree of obesity, had different causes: one was related to working conditions, and one was related to smoking cessation. For the other terminal groups, further factors related to obesity were revealed.

CONCLUSION

Although the applicability of the findings is limited, the methodology using signal detection analysis might be applicable to other weight loss programs as a way of facilitating the matching of the type of intervention and the target group.
