MONTERROSA-CASTRO, Álvaro; ROMERO-MARTINEZ, Shairine  y  MONTERROSA-BLANCO, Angélica. Excessive daytime sleepiness identified with the Epworth scale in pregnant women attending an outpatient prenatal consultation. Rev. chil. obstet. ginecol. [online]. 2021, vol.86, n.3, pp.265-273. ISSN 0048-766X.


Sleep disturbances are constantly reported during pregnancy, although they are not often taken care of in prenatal care. The aim was to estimate the regularity and identify factors associated with excessive daytime sleepiness (EDS) in pregnant women at low obstetric risk who attended prenatal consultation.


Cross-sectional study belonging to the project “Biopsychosocial health in pregnant women”, approved by the ethics committee of the Santa Cruz de Bocagrande Clinic, Cartagena, Colombia. Pregnant women with 12 or more weeks of gestation were studied. A form including: Epworth Daytime Sleepiness Scale, 10-item Perceived Stress and the Revised Depression Scale of the Centre for Epidemiological Studies was applied. Adjusted and unadjusted logistic regression was performed between EDS with the other scales and qualitative variables. In addition, correlation between quantitative variables and the Epworth scale. P<0.05 was significant.


683 pregnant women were studied, maternal age 28.3 ± 6.3 years and gestational age 31.5±6.9 weeks. Epworth Scale score: 3.82 ± 3.45. EDS was identified in 4.9%, 50% mild, 32.2% moderate and 17.6% severe. It was not observed in the first gestational trimester and the frequency was similar in the others, severe EDS only in the third trimester. Depression OR: 3.69 [95% CI: 1.83-7.43], anemia OR: 3.10 [95% CI: 1.50-6.38], fatigue OR: 3.22 [95% CI: 1.23-8.44], nervousness OR: 2.49 [95% CI: 1.22-5.12, stress OR: 2.38 [95% CI: 1.12-5.05], high parity OR: 2.64 [95% CI: 1.01-6.89] and working outside the home OR: 2.33 [95% CI: 1.05-5.15, were associated with EDS. In the adjusted model, anemia OR: 3.05 [95% CI: 1.44-6.45] and depression OR: 2.72 [95% CI: 1.26-5.85] retained the association.


In one out of every twenty low obstetric risk pregnant women EDS was identified and several biopsychosocial situations were associated with more presence.
