VASCO GOMEZ, Ana et al. Relationship between sleep quality, anxiety and depression in patients with chronic kidney disease on hemodialysis. Enferm Nefrol [online]. 2018, vol.21, n.4, pp.369-376. ISSN 2255-3517.


Sleep disorders have a high prevalence in patients with chronic kidney disease (CKD) on hemodialysis (HD). Insufficient or poor quality rest negatively influences daily activity, being the cause or consequence of depressive or anxious states.


To evaluate the quality of sleep of patients on hemodialysis and the relationship with levels of depression and anxiety.

Material and Method:

Descriptive observational study including 28 HD patients during February 2017. Sociodemographic data were collected, the Pittsburg Sleep Quality test was administered, the cognitive status was assessed with the Mini-Mental test and anxiety and depression was assessed with the Hospital Anxiety and Depression Scale (HADS).


According to the Pittsburg Sleep Quality test, 82.14% (n=23) presented insomnia. HADS was positively related to anxiety in 21% (n=6) of population and to depression in 35% (n=10). The results in the Pittsburgh test correlated positively with levels of anxiety (p=0.004) and depression (p=0.049). The degree of depression correlates negatively with the absence of cognitive impairment (p=0.010).


The sleep quality in the examined patients is poor and can be related with the depression and anxiety results. According to that results, we will include information about healthy sleep habits in the HD patients’ education process, as well as we intend to improve management and specialized treatment of anxiety and depression.

Keywords : quality of sleep; insomnia; depression; anxiety; hemodialysis.
