Association of Sleep Disorders with Pregnancy Outcomes During the Third Trimester

Abstract

Background: Pregnancy is a significant cause of sleep disorders, leading to adverse effects on the health of the mother and fetus. Objectives: The current study aimed to investigate the association of sleep disorders with pregnancy outcomes during the third trimester. Methods: Following a descriptive-analytical approach, 100 pregnant women referring to the prenatal clinic of Mousavi Hospital of Zanjan City from April to September 2021 were recruited by convenience sampling. Data were collected using the Pittsburgh Sleep Quality Questionnaire, filled by mothers, and a researcher-made checklist on pregnancy outcomes. Data were analyzed using the SPSS version 24, and the significance level was considered at P ≤ 0.05. Results: The mean age of participants was 32.43 ± 4.6 years and, 46 (46%) participants were at the age of 36 years and older, 62 (62%) participants were nulligravid, and 65 (65%) participants were nulliparous. There was a significant association between study outcomes (low birth weight, intrauterine growth delay, preterm, preeclampsia, gestational hypertension, and gestational diabetes) and sleep disorders (P-value = 0.001). Conclusions: It seems that sleep disorders result in adverse pregnancy outcomes; however, further studies are needed to extend our knowledge.
