[Factors associated with sleep quality during first and second trimester in Chinese pregnant woman].

Objective: To investigate sleep quality in pregnant women during their first and second trimester and to identify risk factors. Methods: Data was from the Chinese Pregnant Women Cohort Study. A total of 3 618 pregnant women were included, with the exclusion 346 women who had missing information. Sociodemographic, health-related behavior, depression and sleep quality information were collected and analyzed. Logistic regression analysis were used to explore the influencing factors of sleep quality in pregnant women. Results: Among the 3 618 pregnant woman 28.2% had poor sleep quality in their first trimester and 28.7% in the second trimester. 15.2% pregnant women had progressively worse sleep and 13.0% had persistently poor sleep had pregnant women were generally suffered from poor sleep quality, difficulty falling asleep, sleep disorders and daily fatigue. Regular diet (OR=0.75, 95%CI: 0.62-0.92) and work (OR=0.84,95%CI: 0.71-0.99) in the first trimester were protective factors of sleep quality in pregnant women. Age ≥30 year old (OR=1.19, 95%CI: 1.03-1.37), passive smoking (OR=1.18, 95%CI: 1.02-1.36) and depression (OR=2.25, 95%CI: 1.95-2.61) in the first trimester were risk factors. Conclusions: The rate of poor sleep quality are high among Chinese pregnant woman during their first and second trimester. The risk factors of sleep quality are multiple. Regular diet and work, reduction of tobacco exposure, alleviation of depression symptom may help improve sleep quality among pregnant women.目的： 了解我国孕妇孕早、中期睡眠质量和变化及其影响因素，为有针对性地提高孕妇睡眠质量和健康水平提供科学依据。 方法： 选取中国孕产妇队列研究·协和（CPWCS）孕早、中期孕妇数据。问卷调查获取一般人口学特征、怀孕意向、健康相关行为、抑郁和睡眠质量信息。描述孕早期、孕中期睡眠质量并比较其在不同人群特征下的分布情况，logistic回归探究孕早、中期睡眠质量的影响因素。 结果： 共调查3 618名孕妇，孕早、中期睡眠障碍发生率为28.2%和28.7%；13.0%的孕妇在孕早、中期持续存在睡眠障碍，15.2%的孕妇睡眠质量下降。睡眠质量差、入睡时间长、存在睡眠障碍、日间困倦是我国孕妇睡眠的主要问题。孕早期规律饮食（OR=0.75，95%CI：0.62~0.92）、孕期在业（OR=0.84，95%CI：0.71~0.99）是孕妇睡眠质量的保护因素；孕妇年龄≥30岁（OR=1.19，95%CI：1.03~1.37）、孕早期被动烟草暴露（OR=1.18，95%CI：1.02~1.36）、抑郁症状（OR=2.25，95%CI：1.95~2.61）是孕妇睡眠质量的危险因素。 结论： 我国孕妇孕早期、孕中期睡眠障碍发生率较高，部分孕妇存在孕早、中期睡眠质量下降或持续存在睡眠障碍的情况。关注高龄孕妇、鼓励孕妇规律饮食、减少被动吸烟，减轻抑郁症状可能有助于孕妇睡眠质量的提高。.
