Introduction. Sleep complaints are commonly reported during pregnancy. Sleep disturbancesare typically exacerbated in the first and third trimester because of pregnancy-related anato-mic changes and hormonal adaptations.Aim.The aim of this research is to assess the frequency of low sleep quality, daytime sleepi-ness among pregnant women taking into account different etiological factors.Material and methods. 147 pregnant women from the Perinatology Department of MedicalUniveristy of £ódŸ were interviewed to assess their sleep alterations. Taking medicines andconcomitant disorders which can affect low sleep quality were eliminated. 140 women inreproductive age represent the control group. The survey was comprised of demographic partand two tests: PSQI (Pittsburgh Sleep QualityIndex), ESS (Epworth Sleepiness Scale) asses-sing sleep quality and daytime sleepiness respectively. Statistical analysis was performed bymeans of Statistica. Results.The survey confirmed sleep disorders amid 90,5% of pregnant women. Comparativeanalysis between pregnant patients and control group revealed a statistically significant dif-ference in frequency of poor sleep quality and daytime sleepiness (p<0,05). Simultaneouslythe impact of sleep disorders on ESS score was not confirmed (p>0,05). However there isa statistical connection between stress level, trimester of pregnancy and PSQI score. The mostoften causes of sleep disorders were an inconvenient position during sleep, necessity of goingto the toilet at night and intensified stress. Sleep disorders increase in I and III trimester ofpregnancy and have a complex etiological background.Conclusions. Received data suggests a tenuous relation between low sleep quality and day-time sleepiness. Incorrect scores of test which estimates the sleep quality were much more oftenobserved among pregnant women than in control group (90,5%; 45,7% respectively).
