Sleep in Heathy Pregnancy: Preliminary Results
Sleep disruption is frequent during pregnancy. An increased prevalence of insomnia, sleep fragmentation due to increased urination and discomfort, excessive daytime sleepiness (EDS), sleep-disordered breathing and restless leg syndrome are reported. Nowadays the importance of sleep quality to a heathy pregnancy is warranted, and sleep disturbances may be recognized as a novel risk factor to adverse pregnancy outcomes such as preeclampsia, gestational diabetes, prematurity, prolonged labor and depression. Furthermore, the sleep profile can be influenced by regional characteristics. To date, studies evaluating sleep quality and circadian preference in healthy pregnancy are scarce in our country.
To investigate the quality of sleep and circadian preference in healthy pregnant women (HPW) attending a low risk prenatal clinic in Northeast Brazil
A cross-sectional study designed to investigate sleep profile of HPW attending a primary care unity. Diabetes or hypertension backgrounds were excluded. Subjective sleep quality was evaluated by Pittsburgh Sleep Quality Index (PSQI); Insomnia (Insomnia Severity Index -ISI), EDS by the Epworth Sleepiness Scale (ESS). Circadian preference assessed by the Horne-Östberg Morningness-Eveningness Questionnaire (MEQ). The study was approved by Instituto para Desenvolvimento da Educação Ltda-IPADE ethic board, approval number 88692918.1.0000.5049.
Seventy two HPW aged 18 to 42 years (mean: 28±6), gestational age (28 ± 7) and BMI (28.2±4) were evaluated. Poor sleep quality was found in 42% (PSQI:5.6±3); EDS in 28% (ESS: 7.6 ±4), mild to moderate insomnia in 27.8% (ISI:5.3±3). Short sleep was reported in 24.3%, and 15% slept > 10 hours/day. Overall, mean sleep duration was 8 ±1.9. Sleep quality was not related to physical activity (p=0.2), years of study (p= 0.16) marital status (p=0.6). Everningness was perceived in only 2 patients. Previous history of depression or anxiety was found by 12% and poor sleep quality and insomnia was present in 62% of them. As expected, insomnia score was significantly related to PSQI score (p=0.001)
In similarity with previously reported studies (SEDOV 2017; BOURJEILY 2013), these preliminary findings suggest that sleep disturbances are frequent in HPW. Interesting to note the low prevalence of eveningness, even in this young group. To our knowledge, this is the first report of sleep profile and circadian preference in HPW in the Northeast of Brazil
