Abstract: Objective To investigate the sleep status of infants and toddlers aged 0 - 35 months in Nanchang,in order to provide evidence for early sleep healthcare and development of good sleep behaviors. Methods A cross-sectional study was conducted,and healthy infants who underwent physical examination in Jiangxi Provincial Maternal and Child Health Hospital from August 2021 to November 2022 were included.Parents were asked to complete Brief Infant Sleep Questionnaire (BISQ),then sleep-related factors were analyzed. Results Among the 717 infants in Nanchang city,23.7% slept in child beds,3.6% fell asleep independently,38.6% of infants went to bed before 21:00,82.1% of infants had regular sleep,and 56.6% of infants slept on their backs before the age of 1 year.The average sleep duration was (9.02±1.33) hours at night,(3.49±1.68) hours during the day,and (12.51±1.81) hours throughout the day,and 79.9% were within the recommended range.The proportion of latency period <20 minutes was 49.7%,and 57.4% of children aged 1 year and older had normal nighttime awakenings.As the age increased,the duration of daytime sleep (F=128.070),total sleep duration (F=68.615),and night waking duration (H=95.948) gradually decreased accordingly (P＜0.05).Compared to the 0 - 3 months group,the 4 - 11 months and 12 - 35 months groups had more regular sleep pattern and longer nighttime sleep duration.The proportion of children falling asleep before 21:00 was the lowest in the 12 - 35 months group,with a reduction in falling asleep through feeding,rocking,and cuddling compared to the other two groups,along with a decrease in nocturnal awakenings.The proportion of children falling asleep before 21:00 was the highest in the 4 - 11 months group,with a shorter latency period and a lower percentage (<20 minutes) compared to the other two groups (P<0.05). Conclusions There are many poor sleep behaviors among infants and toddlers aged 0 - 35 months in Nanchang.It is recommended to start early strengthening sleep education and anticipatory guidance for caregivers to foster good sleep habits in infants and toddlers.

摘要： 目的 了解南昌市0~35月龄婴幼儿睡眠现状,为开展早期睡眠保健、培养良好睡眠行为提供科学依据。方法 采用横断面研究,选取2021年8月至2022年11月在江西省妇幼保健院体检的717名健康婴幼儿作为研究对象,采用简明婴幼儿睡眠问卷了解睡眠情况、分析睡眠现状。结果 南昌市717名婴幼儿中23.7%睡于儿童床内,3.6%独自入睡,38.6%的婴幼儿21:00前入睡,82.1%的婴幼儿睡眠规律,1岁以前56.6%仰睡;平均睡眠时长夜间(9.02±1.33)h、白天(3.49±1.68)h、全天(12.51±1.81)h,79.9%在推荐范围内;49.7%的婴幼儿睡眠潜伏期<20min,1岁以上幼儿57.4%夜醒在正常范围内。随着月龄段增加,白天睡眠时长(F=128.070)、总睡眠时长(F=68.615)和夜醒时长(H=95.948)逐渐减少(P<0.05);4~11月龄、12~35月龄组相较于0~3月龄组睡眠规律性更强、夜间睡眠时长增加;12~35月龄组21:00前入睡的比例最低,相较0~3月龄及4~11月龄组通过喂食、摇晃、拥抱入睡者减少,夜醒次数减少;4~11月龄组21:00前入睡的比例最高,潜伏期时长<20min占比少于0~3月龄及12~35月龄组(P<0.05)。结论 南昌市0~35月龄婴幼儿不良睡眠行为较多,建议早期开始加强对养育人的睡眠科普宣教及预见性指导,以利于婴幼儿良好睡眠习惯培养。
