Introduction: Old age brings greater likelihood of chronic diseases, including cancer. An important consequence of cancer is the poor quality of sleep, which is more common in the elderly. Objectives: To evaluate the relationship between sleep quality and fatigue in elderly patients with cancer diagnosis undergoing outpatient chemotherapy treatment, as well as to identify possible association between sleep quality and clinical and socio-demographic variables. Subjects and Methods: Cross sectional, descriptive study conducted with a non-probability sample of 140 elderly (mean age 69.8 years SD = 6.8; 52.1% female, average schooling of 4.0 years), developed at two specialized cancer services of a university hospital in Southeastern Brazil . Data were collected through interviews and by consulting medical charts, using the instruments: Sociodemographic and Clinical Questionnaire, Pittsburgh Sleep Quality Index (PSQI) and Piper Fatigue Scale-revised. The instruments demonstrated good internal consistency, with Cronbach's alpha of 0.71 for PSQI and 0.98 for Piper Scale. According to Kolmogorov-Smirnov test, continuous variables showed non-normal distribution. Analysis: descriptive statistics; Chi-square test in order to assess the association between categories of sleep quality (good or bad) and socio-demographic and clinical data; Mann-Whitney test to compare the distribution of numerical variables according to categories of sleep quality, and distribution of sleep quality scores according to the categories of socio-demographic and clinical data. A univariate logistic regression model was fit to evaluate possible risk factors associated with sleep quality (p ? 0.20 in bivariate analysis). The value of p <0.05 (? = 5.0%) was adopted as the critical level for all tests. Results: Results show that 62.9% of subjects had poor sleep quality and 37.1%, good-quality sleep, according to the PSQI. Overall mean scores were 7.7 (SD = 4.0), median 7.0, indicating poor sleep quality. It was observed that 30.7% of subjects reported less than six hours of night sleep. Fatigue was reported by 42.9% of the elderly, the highest score assigned to Affective Dimension (mean 3.7, SD 4.3, median 0.0). Significant association was found between bad sleep quality and: fatigue (p = 0.03); pain (p = 0.00). The elderly with poor sleep quality reported greater pain intensity (p = 0.00) and scored significantly higher (p <0.05) in Behavioral and Sensorial/psychological dimensions of Piper Scale, compared to those with sleep good quality. A multiple logistic regression analysis revealed that, as the intensity of pain rises one point on the scale of pain, there is an increasing of 21% in the probability of having poor sleep quality. Conclusions: This study points to the relationship between fatigue, pain and poor sleep quality in cancer patients, stressing the need to evaluate and treat them as a whole.
