Relationship Between Dream Anxiety In Recurrent Nightmare And Indefinite Complaints In Patients Undergoing Maintenance Hemodialysis: A Cross-Sectional Study

The objective of this study was to investigate the relationship between recurrent nightmare and indefinite complaints and to determine the explanatory variables of indefinite complaints related to nightmares in hemodialysis (HD) patients. Sleep quality and dream anxiety in nightmare were assessed with the Athens Insomnia Scale and Van Dream Anxiety Scale. Using a visual analog scale and the Beck Depression Inventory, we assessed the presence of indefinite complaints and levels of depressive symptoms, respectively. Moreover, logistic regression analysis was performed to determine the risk factors of dream anxiety in recurrent nightmare. The presence of feelings of malaise was an independent risk factor of recurrent nightmare (OR, 1.360; p = 0.0083). Adjustment for the presence of feelings of malaise could help to reduce the frequency of nightmares or sleep disorders in patients undergoing HD treatment. Our findings will be useful when considering adjustment of the HD dose.
