Effect of sleep disorders on threatened premature delivery
Abstract
Aim: The present observational study aimed to clarify the effects of sleep disorders on threatened premature delivery, especially preterm uterine contraction. Methods: The participants included 122 healthy singleton pregnant women. The Pittsburgh sleep quality index was used to evaluate the quality of sleep during the previous month at the initial examination and at 16, 24, and 32 weeks of gestation; scores >5 indicate poor sleep. Threatened premature delivery was defined as preterm uterine contraction >6 times/h and requiring tocolytic therapy before 37 weeks of gestation. We analyzed the relationship between poor sleep and threatened premature delivery. Results: Poor sleep affected 27% (n=33) at the initial examination, 34% (n=41) at 16 weeks, 37% (n=45) at 24 weeks, and 41% (n=50) at 32 weeks of gestation. There were 23 patients (19%) with threatened premature delivery. Poor sleep affected 35% and 25% of patients with threatened and non-threatened premature delivery at the initial examination, respectively, 52% and 29% at 16 weeks, 48% and 34% at 24 weeks, and 43% and 40% at 32 weeks of gestation. Conclusions: Sleep disorders at 16 weeks of gestation were the most significantly associated with threatened premature delivery.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
