“…Additionally, women in their third trimester of pregnancy showed an increased prevalence of excessive sleep duration during pregnancy. A previous study conducted in Japan showed that excessive daytime sleepiness was significantly higher in an earlier trimester of pregnancy [ 18 ]. Almost all Chinese pregnant women with jobs were on maternity leave in the third trimester of pregnancy and, thus, they were more likely to have time to sleep longer.…”

“…Previous studies showed that age and marital status [ 14 ], low socioeconomic status [ 15 ], employment during pregnancy [ 16 ], number of pregnancies [ 17 ], trimester of pregnancy [ 18 ], passive smoking [ 19 ], and smoking and drinking [ 20 ], are associated with sleep duration among pregnant women. Previous studies showed that poor sleep quality was associated with various factors, including age [ 14 ], low socioeconomic status [ 15 ], at later stage of pregnancy [ 21 ], higher education [ 22 ], residence [ 7 ], minorities [ 23 ], and parity [ 24 ], smoking and drinking [ 20 ], sleeping duration of less than 7 h [ 25 ] among pregnant women.…”

Objectives: Good maternal health and fetal development require sufficient and good quality of sleep during pregnancy. This study investigated sleep duration and quality in pregnant women, assessing factors with possibly influence on sleep. Method: A cross-sectional survey was conducted on pregnant women between June and August in 2015 in 16 hospitals in five provinces in China. A total of 2345 pregnant women aged 18 years and older were surveyed. Insufficient sleeping duration was defined as sleeping of less than 7 h per day. Excessive sleep duration was defined as sleeping of more than 9 h per day. Results: A total of 561 (23.9%) participants reported insufficient sleeping duration, whereas 485 (20.9%) claimed excessive sleep duration. A total of 358 (15.2%) of pregnant women reported problems regarding sleep quality. Compared to pregnant women with sufficient sleeping duration, those with insufficient sleeping duration were prone to have poor sleep quality, whereas those with excessive sleeping duration featured low possibility of poor sleep quality. High-risk groups of insufficient sleep duration include women of Han nationality, with siblings, in their first trimester of pregnancy, receiving care in low-capacity/quality hospital settings, and with daily or 1–3 days of secondhand smoke exposure. High-risk groups of excessive sleep duration include women living in rural areas, unemployed, in their third trimester of pregnancy, and receiving care in medium-capacity/quality hospital settings. High-risk groups of poor sleep quality include women of non-Han nationality, low income level, in their third trimester of pregnancy, and with insufficient sleep duration. Conclusions: Insufficient/excessive sleep duration and poor sleep quality commonly occur during pregnancy in China. Findings provide a better understanding of the influencing factors of insufficient/excessive sleep duration and poor quality of sleep. These findings have some implications for future interventions on sleep among pregnant women.

“…Several studies on sleep disturbances during pregnancy have been conducted. In an epidemiological survey conducted in 2014, excessive daytime sleepiness was reported in 6.2% of pregnant women, especially among those who were younger and working full-time [4]; the survey also clari ed that pregnant women with sleep-related problems such as alcohol drinking, restless sleep, snoring, apnea, and restless leg syndrome also experienced excessive daytime sleepiness. In another survey, it was estimated that 10-46% of pregnant women started snoring after the second trimester of pregnancy; additionally, the incidence of snoring increased from approximately 11% in the rst trimester of pregnancy to 25% in the third trimester [5].…”

Background Sleep disturbances due to hormonal imbalance are common during pregnancy. Studies have suggested that poor sleep quality in pregnant women can lead to perinatal abnormalities; therefore, the need of the hour is to determine the actual circumstances of sleep during pregnancy from an early stage, and provide support for better sleep quality. Therefore, the present study aimed to assess sleep quality by objective assessment using an actigraph and subjective assessment using a questionnaire for sleep during each trimester of pregnancy, and to elucidate how sleep quality changed from the first to the third trimester of pregnancy. Methods A longitudinal questionnaire survey and sleep measurements using actigraph were conducted at three time points, during the first, second, and third trimester, of pregnancy for primiparous women who had conceived naturally. Results During the first trimester of pregnancy, there was no “feeling of being refreshed when waking up in the morning,” and there was a decline in mental function. During the second trimester of pregnancy, a positive correlation between morning sickness and sleep quality (r = 0.59, p = 0.001) was observed. Sleep quality was the worst during the third trimester, with the shortest total sleep time (382.6 ± 26.3 min, F = 11.7, p = 0.0001) and poor sleep efficiency (93.9%±3.2%, F = 4.1, p = 0.0029). Physical function score was also poor. Regarding minor troubles that affected sleep efficiency, back pain (r = 0.47, p = 0.03) and leg cramps (r = 0.57, p = 0.01) exhibited significant correlation with sleep efficiency in the third trimester of pregnancy. Conclusions Poor sleep during pregnancy begins from the first trimester; if minor troubles such as morning sickness continue in the second trimester, sleep quality is greatly affected. Furthermore, during the third trimester of pregnancy, low back pain and leg cramps are more likely to occur due to the increase in the abdominal area, and may interfere with sleep.
