The relation between cumulative fatigue and marital status in Japanese workers.

The authors' aim in this study was to clarify the influence of marital status on mental and physical fatigue symptoms. For 5,582 men and 484 women workers, the authors determined odds ratios of marital status using positive findings of 8 subscales on the Cumulative Fatigue Symptoms Index (CFSI) as dependent variables and other potential covariates as independent variables by logistic regression analysis. In men, the odds ratios for decreased vitality, physical disorders, decreased willingness to work, anxiety, and depressive feelings of CFSI were significantly higher in the unmarried group. In women, the odds ratios on CFSI for decreased vitality and decreased willingness to work were likewise significantly higher. The results verified that unmarried status was more associated with fatigue than was married status and being overworked.
