Association between school bullying experience and work-related subjective well-being: A systematic review

Objectives: Work-related subjective well-being (SWB) may be negatively affected by early-life adverse experiences, such as school bullying experience. This study aimed to identify the association between work-related SWB and school bullying experiences. Methods: A systematic review was conducted using five electronic databases to search for published observational studies from inception to May 5th, 2022. Eligibility criteria included the original papers in English, which measured school bullying experiences and work-related SWB (eg, satisfaction, engagement). Eight researchers independently conducted screening and a full-text review. We used the Risk of Bias Assessment tool for Non-randomized Studies to assess the certainty of the evidence. Narrative data were summarized. The study has been registered at UMIN-CTR (UMIN000040513). Results: A total of 6,842 studies were initially searched. We included two cross-sectional studies. Both studies were rated as high risk for bias in exposure measurements and incomplete outcome data. These studies showed conflicting results. One study reported that school bullying was negatively associated with job satisfaction among British lesbian, gay, or bisexual workers; on the other hand, another study reported that school bullying was positively associated with work engagement among Japanese workers. Conclusions: We found limited inconsistent evidence for the association between work-related SWB and school bullying experiences

Plasma free amino acid profiles evaluate risk of metabolic syndrome, diabetes, dyslipidemia, and hypertension in a large Asian population

Abstract Background Recently, the association of plasma free amino acid (PFAA) profile and lifestyle-related diseases has been reported. However, few studies have been reported in large Asian populations, about the usefulness of PFAAs for evaluating disease risks. We examined the ability of PFAA profiles to evaluate lifestyle-related diseases in so far the largest Asian population. Methods We examined plasma concentrations of 19 amino acids in 8589 Japanese subjects, and determined the association with variables associated with obesity, blood glucose, lipid, and blood pressure. We also evaluated the PFAA indexes that reflect visceral fat obesity and insulin resistance. The contribution of single PFAA level and relevant PFAA indexes was also examined in the risk assessment of lifestyle-related diseases. Results Of the 19 amino acids, branched-chain amino acids and aromatic amino acids showed association with obesity and lipid variables. The PFAA index related to visceral fat obesity showed relatively higher correlation with variables than that of any PFAA. In the evaluation of lifestyle-related disease risks, the odds ratios of the PFAA index related to visceral fat obesity or insulin resistance with the diseases were higher than most of those of individual amino acid levels even after adjusting for potential confounding factors. The association pattern of the indexes and PFAA with each lifestyle-related disease was distinct. Conclusions We confirmed the usefulness of PFAA profiles and indexes as markers for evaluating the risks of lifestyle-related diseases, including diabetes mellitus, metabolic syndrome, dyslipidemia, and hypertension in a large Asian population

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
