Abstract

Background: About 79% of the pregnant women experience sleep disorders and 70% of pregnant women experience some symptoms of the depression. Physiologic, hormonal, and physical changes of pregnancy can predispose mothers to depression these disorders before, during, and after childbirth and might be aggravated by neglecting health behavior. Health behavior education might be useful for the management of depression in pregnant women.

Objectives: This study aimed to evaluate the effect of sleep health behavioral education on the improvement of depression in pregnant women with sleep disorders.

Patients and methods: This study was a randomized clinical trial, performed on 96 pregnant women with sleep disorder diagnosed according to the Pittsburgh Sleep Quality Index. Tools for data collection included demographic questionnaire and Beck's Depression Inventory (BDI). Easy and accessible sampling was done. Participants were randomly (simple) allocated to intervention and control groups. In intervention group, sleep health behavior education was presented during a four-hour session held in weeks 22, 23, 24, and 25; then the patients were followed up to fill out the BDIQ in follow-up session at weeks 29 and 33 of pregnancy. The control group received no intervention and only received routine prenatal care. The results were assessed by Chi-square tests, independent-samples t-test, and Fischer's exact-test by SPSS 16.

Results: A statistically significant change was reported in the severity of depression in pregnant women with sleep disorders in the intervention group in comparison to the control group at weeks 29 (P < 0.000) and 33 (P < 0.00).

Conclusions: Sleep health behavioral education improves depression in pregnant women who are experiencing insomnia. Findings from this study add support to the reported effectiveness of sleep health behavioral education in the prenatal care and clinical management of insomnia in pregnancy.
