5HTT polymorphisms are associated with job stress in Japanese workers

Usage of the Brief Job Stress Questionnaire: A Systematic Review of a Comprehensive Job Stress Questionnaire in Japan from 2003 to 2021

The Brief Job Stress Questionnaire (BJSQ) is used widely in occupational health studies and practice. Summarizing scientific production based on measurement is crucial. This study aimed to systematically review observational studies that used the BJSQ and the New BJSQ to show their usability. A systematic search was conducted for studies investigating relationships between the BJSQ or the New BJSQ subscales and other validated measurements on 13 September 2021, in various literature databases. The BJSQ subscales, scoring methods, and other validated measurements in the studies were qualitatively summarized. In total, 145 published reports between 2003 and 2021 were included. Among the BJSQ subscales, job stressors (n = 95) such as quantitative job overload (n = 65) and job control (n = 64) were most often used. The subscales were utilized to investigate the relationships with several other measurements. Five reports used subscales from the New BJSQ. In the last two decades, the BJSQ and the New BJSQ help measure psychosocial factors (PF) at work and contribute to the publication of scientific papers in the occupational health field. This study would encourage the utilization of the questionnaires for future research and practice.

Intergenerational Ties in Context: Association between Caring for Grandchildren and Cognitive Function in Middle-Aged and Older Chinese

Grandchild caregiving is suggested to improve the elderly’s cognitive function, but the specific relationship remains under-investigated. Considering gender disparity, this study aimed to understand the relationship between grandchild caregiving and cognition. In total, 7236 Chinese residents (≥45 years old) were selected from the 2015 China Health and Retirement Longitudinal Study (CHARLS). The China Health and Retirement Longitudinal Study Harmonized Cognitive Assessment Protocol (CHARLS-HCAP) was used to measure cognition. Grandparenting was measured from three dimensions: caregiving frequency, intensity, and the number of grandchildren cared for. The relationship was examined by multivariate linear regression, with age as a moderator. The results showed that the majority of respondents provided care to their grandchildren, especially grandmothers. Grandchild caregiving was positively associated with cognition (β = 0.686, 95% CI = 0.334–1.038), especially in the older-aged group. Moderate, not regular grandparenting, or caring for one grandchild was more positively associated with cognitive function. However, intensive and regular grandchild care was significantly associated with cognition only in men. No moderating effects of age were found in women. The study confirmed that moderate intensity and frequency of caregiving was related to better cognitive function in middle-aged and older Chinese population, whereas cultural context and gender differences could be considered when designing targeted policies.

The influence of genetic factors on personality and coping with stress among healthy late reproductive age women

Background

Psychological stress is a factor which predisposes people to many somatic and mental disorders. Women are at a significantly higher risk of stress than men, and their reactions to stress are stronger. Personality traits are thought to play a special role in the psychology of stress and may be crucial for the choice of a stress-coping strategy. Considering that stress is so common in everyday life, an attempt to understand how stress-coping styles are related to personality and genetic factors acquires special significance.

Purpose

The aim of this study was to analyze stress-coping styles and personality traits in healthy late reproductive age women with regard to genetic factors.

Patients and methods

The study involved 345 healthy late reproductive age women from northwest Poland, whose mean age was 42.3±4.5 years. The study was conducted using The Coping Inventory for Stressful Situations, The Neuroticism-Extraversion-Openness Five--Factor Inventory, and genetic testing.

Results

There were neither statistically significant relationships between personality traits and the genotype distribution of the 30-bp VNTR polymorphism in the MAO-A promoter region, nor between stress-coping styles and the genotype distribution of the 30-bp VNTR polymorphism in the MAO-A promoter region.

Conclusion

Based on the results, all personality traits statistically significantly correlated with the choice of task-oriented coping and emotion-oriented coping. Some of personality traits are genetically determined. The choice of a stress-coping style was significantly related to personality traits. A direct influence of genetic factors on the choice of a stress-coping style was not confirmed in our study.

Análise da percepção da fadiga, estresse e ansiedade em trabalhadores de uma indústria de calçados

OBJETIVO: Descrever e correlacionar os aspectos envolvidos com a percepção de fadiga e estresse laboral e percebido em trabalhadores de ambos os sexos, em função do setor de trabalho e traço de ansiedade. MÉTODOS: Foram avaliados 46 trabalhadores de uma indústria calçadista, por meio dos instrumentos: Inventário de Ansiedade Traço-Estado (IDATE), Questionário de Fadiga de Yoshitake, Escala de Estresse no Trabalho e Escala Visual Analógica (EVA) para o estresse percebido. Os dados foram analisados por meio do teste t de Student e do teste de correlação de Pearson para p ≤ 0,05. RESULTADOS: Não foram verificadas diferenças significativas entre os sexos e entre os trabalhadores dos diferentes setores, quanto a fadiga, traço de ansiedade, estresse laboral e percebido. Quanto à fadiga, os trabalhadores com traço de ansiedade alto apresentaram maior nível de fadiga comparados àqueles que apresentavam traço de ansiedade baixo (p < 0,001). Foram observadas também correlações positivas entre as variáveis investigadas conforme o sexo, setor de trabalho e nível de ansiedade entre os trabalhadores. CONCLUSÃO: A percepção de fadiga afeta principalmente os trabalhadores que apresentam traço de ansiedade alto. Contudo, percebe-se, por meio dos testes de correlações, que as variáveis sexo, setor de trabalho e traço de ansiedade podem modular os níveis de fadiga e estresse laboral e percebido entre os trabalhadores.
