Beijing children
Area of Science:
- Pediatric Sleep Research
- Public Health
- Child Development
Background:
- Assessing children's sleep is crucial for their health and development.
- Understanding sleep patterns in urban populations like Beijing is important.
Purpose of the Study:
- To determine the current state of sleep among children in Beijing.
- To identify key factors affecting children's sleep quality.
Main Methods:
- A large-scale study involving 11,420 children aged 3-14 years in Beijing.
- Utilized multi-stage stratified cluster random sampling for participant selection.
- Employed the Pediatric Sleep Questionnaire (PSQ) for data collection.
Main Results:
- The average Pediatric Sleep Questionnaire (PSQ) score was 3.60 ± 2.69.
- 8.87% of children scored above 7 on the PSQ, indicating potential sleep issues.
- Younger children and boys exhibited higher PSQ scores compared to older children and girls, respectively.
Conclusions:
- Children's sleep quality in Beijing is a significant concern.
- Preschool-aged children reported poorer sleep than school-aged children.
- Recommendations include parental attention to sleep status and addressing influencing factors.
Objective:
To investigate the current status of children's sleep in Beijing and analyze the factors that influence it.
Materials And Methods:
Using multi-stage stratified cluster random sampling, a total of 11 420 children aged 3 to 14 years in 7 districts of Beijing were included in this study. The Pediatric Sleep Questionnaire (PSQ) was used to investigate and analyze various factors influencing sleep.
Results:
The mean PSQ score of the children surveyed was 3.60 ± 2.69 points. The proportion of children with a score above 7 was 8.87%. Multi-level model analysis showed that the younger children had higher PSQ scores than older and that the boys had higher PSQ scores than the girls.
Conclusions:
The sleep quality of children in Beijing is not optimistic. The PSQ score of preschool children is higher than school age children. It is recommended that parents pay attention to their children's sleep status and try to remove influencing factors.
