The relationship between quality of sleep and quality of life in nurses

 Sleep is essential for physiological and psychological balance and hemostatic adaptation. The nursing profession is related to shift working and sleep disorders. The present study was conducted to investigate the relationship between sleep quality and quality of life in nurses.

The present descriptive-analytical and cross-sectional study was performed on two-hundred nurses of 5th Azar hospital in Gorgan city, Iran. The nurses were selected by stratified sampling and then in each section by simple random sampling. Data collected through demographic characteristics, the Pittsburgh Sleep Quality Index (PSQI), and the Short Form Quality of Life Questionnaire (SF-12). The data were analyzed using descriptive statistics, paired t-test, Wilcoxon test, and SPSS-16.

Based on the findings, fifty-six (28%) nurses had good sleep quality and one-hundred and forty-four (72%) nurses had poor sleep quality. Nurses with good sleep quality had a PSQI test score of 39.87 ± 5.7, and nurses with poor sleep quality had a test score of 33.96 ± 7.05. Among nurses with good sleep quality, they had no poor quality of life, 30.9% had a medium level of quality of life, and 69.1% had good quality of life. In nurses with poor sleep quality, 11.8% had poor quality of life, 51.4% had a medium level of quality of life and 36.8% had good quality of life (P<0.001).

It seems that reducing the quality of sleep of nurses can reduce their quality of life in various dimensions.
