Background: About 79% of pregnant women in the world suffer from sleep disorders. These disorders result from physiological changes during pregnancy, originate from different factors, and can affect pregnant women’s quality of life before, during, and after delivery. This study aimed to investigate the effect of sleep healthy behavior education on the quality of life among pregnant women with sleep disorders in the second trimester. Materials and Methods: This is a clinical trial conducted on 112 pregnant women with sleep disorders referring to two selected health care centers in Makou affi liated to Urmia University of Medical Sciences during June-Oct 2012. Data collection tools included demographic characteristics questionnaire, Pittsburgh Standard Sleep Quality questionnaire, and World Health Organization, Quality of Life (WHOQOL-BREF) WHOQOL-BREEF questionnaire. Sampling was done by convenient sampling. Firstly, Pittsburg Standard Sleep Quality Questionnaire was completed and the pregnant women with sleep disorders were selected as the subjects. After completion of sampling, the subjects were randomly assigned to two groups of study and control. Education of sleep health behavior was provided in the study group by the researcher during four 1-h sessions. Then, WHOQOL-BREEF and two groups in the fi rst follow-up session (1 month after educational intervention) and in the second follow-up session (2 months after educational intervention) held by the researcher. Control group only received conventional prenatal care. The obtained data were analyzed by Chi-square test, independent t-test, Fisher’s exact and repeated measure tests through SPSS 18. Results: Mean scores of quality of life showed an increase in 1 and 2 months after intervention in the study group compared to the control group. A signifi cant difference was observed in the QOL in the two groups, 1 month (P < 0.000) and 2 months (P < 0.001) after intervention. Conclusions: Education of sleep healthy behaviors was effective on the QOL of pregnant women with sleep disorders. The results obtained in the present study can be used to support the pregnant women with sleep disorders and sleep disorders clinics, as well as for administration of prenatal care.
