The purpose of this study was to profile sleep patterns during pregnancy according to body mass index (BMI) and to correlate labour outcomes with both BMI and hours sleep. Data were collected from 200 postpartum women detailing sleep characteristics before and during pregnancy. A validated sleep questionnaire was employed, which comprised of questions about sleep apnoea, snoring, subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication and daytime dysfunction. Descriptive analyses were used. With advancing gestation, the mean (SD) number of hours sleep per night declined: pre-pregnancy 8.1 (SD 1.4); 1st trimester 8.3 (SD 1.8); 2nd trimester 7.7 (SD 1.7) and 3rd trimester 6.7 (SD 2.2). In the 18.5-24.9 BMI group, there was a marked difference in hours sleep per night from pre-pregnancy to 1st (8.6 h, p = 0.007), 2nd (7.9 h, p = 0.023) and 3rd (6.4 h, p = 0.000) trimesters in primiparous women. In the 25-29.9 BMI group, there was a difference from pre-pregnancy to 3rd trimester (p = 0.000). These changes were not reflected in a clinically significant difference in birth weight or mode of delivery.
本研究的目的是根据体重指数（BMI）剖析孕期的睡眠模式，并将分娩结局与BMI和睡眠时间相关联。从200名产后女性收集数据，详细记录孕前和孕期的睡眠特征。采用了一份经过验证的睡眠问卷，其中包括有关睡眠呼吸暂停、打鼾、主观睡眠质量、入睡潜伏期、睡眠时间、习惯性睡眠效率、睡眠障碍、使用助眠药物和日间功能障碍的问题。使用描述性分析方法。随着孕周增加，每晚平均睡眠时间（标准差）下降：孕前为8.1（标准差1.4）小时；孕早期为8.3（标准差1.8）小时；孕中期为7.7（标准差1.7）小时；孕晚期为6.7（标准差2.2）小时。在BMI为18.5 - 24.9的组中，初产妇从孕前到孕早期（8.6小时，p = 0.007）、孕中期（7.9小时，p = 0.023）和孕晚期（6.4小时，p = 0.000）每晚睡眠时间存在显著差异。在BMI为25 - 29.9的组中，从孕前到孕晚期存在差异（p = 0.000）。这些变化并未在出生体重或分娩方式上体现出具有临床意义的差异。
