Other Side of Breast Cancer: Sleep Quality

Breast cancer is the most common cancer among women. Many of the women with
breast cancer suffer from sleep disorders. This study aimed to investigate the quality of sleep and its related issues in
women with breast cancer referred to the Hematology and Oncology Research Center affiliated with Tabriz University
of Medical Sciences, Tabriz, Iran.
Materials and Methods: In this cross-sectional study, 103 women with breast cancer were chosen using the census
method. Data were collected using the Pittsburgh Sleep Quality Index. Descriptive and analytic statistics and linear regression test were used for data analysis.
Results: The mean age of the sample was 42.59 years [standard deviation (SD): 11.72 years] and the average length
of diagnosis was 19.90 months (SD: 12.67 months). The mean score of sleep quality was 11.50 (SD: 3.71) in a range
from 0 to 21. Except the history of mastectomy, age, smoking status, the remaining demographic data could predict
39.5% of the variance of sleep quality.
Conclusion: The results of this study are a wakeup call for officials. To prevent the negative impact of poor quality
of sleep, there is a need to design holistic and appropriate interventions. The findings provide valuable information with
scheduling for these interventions
