Abstract
Objective To investigate the sleep status of children aged 2 to 6 years in Zhongshan City, and to analyze the common sleep problems of children with different characteristics.Methods A total of 1 880 children from 6 kindergartens in 5 districts of Zhongshan City were randomly selected from March 2018 to February 2019 by stratified cluster random sampling. The questionnaire was designed based on the Clinical Questionnaire of Sleep Center of Sydney Children's Hospital and cultural background.Finally 1 799 valid questionnaires were collected.Results The average daily sleep time of 2-year-old children in Zhongshan City was 11.37 h, and that of 3- to 6-year-old children was 10.26 to 10.99 h, and it gradually decreased with age in terms of daytime, nighttime and the overall sleep(F=14.285, 28.408, 40.635, P<0.05). The detection rates of insufficient sleep, delayed bedtime, and difficulty in falling asleep were 17.01% (306/1 799), 88.2% (1 587/1 799) and 41% (738/1 799). The outdoor activities and screen time of 2- to 6-year old children were (2.27±1.11) h and (1.25±0.94) h, respectively, which reached the recommended standard for children in China. Children had more sleep problems, mainly manifested as fear of going to bed(64.0%), sweating(50.9%), molars(44.8%), snoring(40.1%), nightmares(39.4%), night terrors(39.1%) and drooling(25.3%), sleepwalking(3.2%) and apnea(0.7%). Conclusion At present, the sleep time of children in Zhongshan City is inadequate, so parents and pediatricians should pay more attention to children's sleep health care to promote their sleep health.
