Abstract To study the correlation between the sleep quality measured by wearable devices of pregnant women during the third trimester of pregnancy and their risk of prenatal depression. Methods: From February 2021 to October 2022, 204 pregnant women who had been given antenatal examination in hospital were enrolled in this study. During the third trimester of pregnancy, these women had worn a wearable sleep detection device (Actiwatch-2) for 7 consecutive days to collect their sleep related data, such as sleep latency, sleep efficiency, night sleep duration, and sleep duration in 24h. The sleep quality and daytime sleepiness of the women were assessed by the Pittsburgh sleep quality index (PSQI) and Epworth sleepiness scale (ESS). The depression of the women was assessed by the center for epidemiologic studies depression (CES-D), with the CES-D score ≥16 points as the threshold of depression identification. Results: There were 61 (29.9%) pregnant women with CES-D score ≥16 points during the third trimester of pregnancy. Multivariate regression analysis found that the unemployment (OR=1.204, 95% 1.119-2.986) and the sleep efficiency rate <85% (OR=3.86, 95% CI 1.72-8.65) of the women were the independent risk factors for their prenatal depression during the third trimester of pregnancy (all P<0.05). Conclusion: The pregnant women during the third trimester of pregnancy have different degree of sleep disorders and have higher incidence of prenatal depression. The unemployment and the rate of sleep efficiency <85% of the pregnant women are the independent risk factors affecting their prenatal depressions.
