Pregnancy significantly increases sleep disorders, particularly excessive daytime sleepiness (EDS) and specific awakenings, compared to the pre-pregnancy state. These sleep disturbances become more prevalent as pregnancy progresses.

Area of Science:

  • Obstetrics and Gynecology
  • Sleep Medicine
  • Public Health

Background:

  • The exact function of sleep remains unclear, with sleep-wake cycles susceptible to various physiological, social, and psychological changes.
  • Understanding sleep patterns during pregnancy is crucial due to potential impacts on maternal and fetal well-being.

Purpose of the Study:

  • To investigate the prevalence of sleep disorders (SD) across the three trimesters of pregnancy.
  • To compare sleep disorder rates during pregnancy with the pre-pregnancy (PG) state.

Main Methods:

  • A clinical interview with directed questions was used to assess sleep disorders in 300 pregnant women aged 11-40.
  • One hundred pregnant women were evaluated for each trimester of pregnancy.

Main Results:

  • Insomnia rates rose by 23% in the second trimester.
  • Excessive daytime sleepiness (EDS) increased significantly, with rates of 15% (1st trimester), 55% (2nd trimester), and 14% (3rd trimester).
  • Specific awakenings showed a marked increase, reaching 84% in the third trimester.

Conclusions:

  • Sleep disorders are more common during pregnancy compared to the pre-pregnancy state.
  • Excessive daytime sleepiness (EDS) and specific awakenings were the most prominent sleep disturbances observed during pregnancy.
