The prevalence of excessive daytime sleepiness (EDS) among pregnant women in Japan is unknown. The aim of this study was to clarify that prevalence, and to analyze the factors associated with EDS. A questionnaire survey was conducted on a sample of 16,528 pregnant women in Japan. The survey items were: attributes, pregnancy status, employment status, current smoking and drinking status. In addition it included a subjective evaluation of sleep, sleep duration, restless legs like symptoms (RLS), and excessive daytime sleepiness. The prevalence of EDS among pregnant women in this survey was 25.5%. Analyses of the relationships between EDS and the subjective evaluation of sleep and EDS and short sleep duration (SSD) were conducted, and the results showed that the frequency of occurrence of EDS in the "insufficient sleep" group (from the subjective sleep evaluation) and the "with SSD" group tended to be higher than in the other groups. As to the relationship between the stage of pregnancy and EDS, the percentage of women with EDS tended to decrease as the pregnancy advanced. Moreover, statistically significant relationships were recognized between EDS and each of the following: schooling completed, number of pregnancies, pregnancy semester, SSD, naps, RLS, drinking, and smoking. Our survey showed that the prevalence of EDS among pregnant women was 25.5%, which is higher than among the general female population, as revealed by a previous study. This indicates that EDS is an important public-health issue among pregnant women in Japan from the viewpoint of improvement of sleep hygiene.
