0848 The Relationship Between Sleep Disturbance & Sleep Hygiene In Japanese Pregnant Women

Abstract

Introduction: Pregnant women are more likely to develop sleep disorders due to poor sleep quality. Sleep hygiene has been reported as a method for dealing with sleep disorders. However, studies on the relationship between sleep hygiene and sleep disorders in Japanese pregnant women remain insufficient. This study aimed to clarify the actual state of sleep disorders during pregnancy and the relationship between sleep disorders and sleep hygiene. Methods: A cross-sectional study was conducted on 147 Japanese pregnant women. We used the Japanese versions of the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (JESS) for evaluation of sleep. We used 32 items of habitual behavior important for sleep improvement for evaluation of sleep hygiene; these items were self-selected. Results: The average PSQIG scores of women in their first, second, and third trimesters were 5.6 ± 4.3, 5.4 ± 2.4, and 6.6 ± 2.8, respectively; 22.2%, 46.4%, and 62.2% of women in their first, second, and third trimesters, respectively, exceeded the cut-off score. The average JESS scores were 12.2 ± 4.5, 9.9 ± 4.1, and 10.0 ± 4.6 for first, second, and third trimester women, respectively; 55.6%, 35.7%, and 41.9% of first, second, and third trimester women, respectively, slept excessively during the day (JESS score≥11). Following factor analysis, sleep hygiene was categorized into four factors: “thinking positively,” “adding rhythm to the day,” “avoiding going out and caffeine before bedtime,” and “avoiding eye irritation.” Pregnant women who “added rhythm to their day” had lower PSQI scores, and sleep hygiene was not related to JESS scores in the multiple regression analysis of sleep hygiene and sleep disorders. Conclusion: Sleep disorders in pregnancy are related to habitual behavior such as being active during the day, eating and sleeping regularly, and basking in the sunlight every morning.
