Background
Presenteeism is the loss of work productivity of workers owing to physical and mental problems, and its socioeconomic effects are greater than those of absenteeism. Presenteeism is caused by psychological and physical dysfunctions. On the other hand, the regularity of mealtimes is an important factor associated with physical and mental health conditions. We hence assessed the association among the irregularity of mealtimes, presenteeism, psychological and physical stress responses, and sleep disturbance in office workers in companies.
Methods
From May to December 2017, the data of 2905 participants who had given their consent to use their information for academic purposes, and answered a questionnaire about the survey and their lifestyle were collected. Path analysis was performed to analyze the association between the irregularity of mealtimes, psychosomatic symptoms (Brief Job Stress Questionnaire), sleep disturbance (Pittsburgh Sleep Questionnaire), and presenteeism (Work Limitations Questionnaire).
Results
The direct effect of the irregularity of mealtimes on presenteeism was significant but weak. However, the irregularity of mealtimes had a strong effect on presenteeism indirectly through psychological and physical stress responses and sleep disturbance.
Conclusion
Psychological and physical stress responses and sleep disturbance were identified as mediating factors of the effects of irregularity of mealtimes on presenteeism.
BackgroundHow subjective social status is associated with childhood abuse and affective temperament in the mechanism of depressive symptom exacerbation remains unknown. In this study, we investigated how the complex effects of subjective social status, childhood abuse, and affective temperament influence depressive symptoms in adulthood.MethodsSelf-report questionnaires were distributed to 853 adult volunteers between January and August 2014. Of them, 404 people gave full consent and returned complete anonymous responses. The following five questionnaires were analyzed: demographic information, Patient Health Questionnaire-9, subjective social status, Child Abuse and Trauma Scale, and Temperament Evaluation of Memphis, Pisa, Paris and San Diego autoquestionnaire. The associations between the scores were analyzed by structural equation modeling. This study was conducted with approval from the ethics committees of Tokyo Medical University and Hokkaido University Hospital.ResultsCovariance structure analysis demonstrated that childhood abuse and subjective social status did not have a direct effect on adulthood depressive symptoms. Childhood abuse had direct effects on subjective social status and affective temperament and childhood abuse indirectly affected adulthood depressive symptoms through subjective social status and affective temperament. Subjective social status also affected depressive symptoms through an effect on affective temperament. This model explained 43% of the variability in depressive symptoms and the fitness of this model was good.ConclusionRegarding childhood abuse and adulthood depressive symptoms, subjective social status as well as affective temperament may be mediators. The results of this study are expected to contribute to the elucidation of the mechanism of depression.
