abstract="PURPOSE: The sleep disorder in pregnant women remains unfamiliar to perinatal care providers, resulting in lack of appropriate care. This study was designed to investigate the prevalence of sleep disorder-related symptoms in pregnant women and to identify the associated risk factors. METHODS: Married pregnant women were enrolled from their first trimester and followed up until delivery. Nonpregnant married healthy women were selected as controls. A survey questionnaire was administered to each of them. RESULTS: We successfully performed a survey to 1,993 pregnant women and 598 nonpregnant women. The overall prevalence of sleep disorder-related symptoms in pregnant women was significantly higher than the controls (56.1 vs. 29.9 %, P < 0.05). There was higher prevalence of snoring (30.2 %), observed sleep apnea (1.1 %), mouth breathing (23.7 %), nocturnal arousal (46.5 %), insomnia (35.1 %), and daytime sleepiness (52.6 %) in pregnant women. There were no significant differences of the prevalence of bruxism (7.0 vs. 6.7 %), sleep talking (8.1 vs. 7.2 %), and sleep walking (0.4 vs. 0.2 %) between the two groups (P > 0.05). Nocturnal sleep time (8.0 ± 1.3 h) was less in the third trimester compared with the nonpregnant women (8.2 ± 1.1 h) (P < 0.05). Smoking (OR = 3.39), drinking (OR = 2.40), allergic rhinitis/asthma (OR = 1.71), an obvious difference in neck circumference (OR = 1.11), and waistline (OR = 1.07) changes between the first and third trimesters were the risk factors for sleep disorder-related problems. CONCLUSIONS: There is a high prevalence of sleep disorder-related symptoms in pregnant women. Our data may provide a baseline for prevention and treatment of sleep disturbances in pregnant women.<p /> <p>Language: en</p>",
