Insights
Children's sleep duration decreases with age and varies by gender, socioeconomic status (SES), and ethnicity. These social and cultural factors influence sleep patterns, impacting healthy sleep recommendations.
Area of Science:
- Pediatric Sleep Science
- Child Development
- Public Health
Background:
- Sleep patterns in school-aged children are influenced by age, but the impact of gender, socioeconomic status (SES), and ethnicity requires further investigation.
- Understanding these demographic factors is crucial for developing culturally sensitive and socially appropriate healthy sleep guidelines for children.
- Previous research has primarily focused on age-related sleep changes, leaving gaps in knowledge regarding socio-cultural influences.
Purpose of the Study:
- To investigate the effects of age, gender, socioeconomic status (SES), and ethnicity on the sleep patterns of school-aged children.
- To identify demographic disparities in children's sleep duration and timing.
- To inform the development of targeted interventions for improving sleep health in diverse pediatric populations.
Main Methods:
- A cross-sectional survey was administered to parents of 1845 children aged 5 to 10 years in primary schools.
- Data collected included demographic information (gender, SES, ethnicity) and sleep patterns on both school and non-school days.
- Statistical analysis examined the influence of age, gender, SES, and ethnicity on sleep duration and bedtime.
Main Results:
- Sleep duration decreased with increasing age and was shorter on non-school days due to later bedtimes.
- Boys, children from low SES backgrounds, and non-Caucasian children reported significantly shorter sleep durations compared to girls, children from high SES backgrounds, and Caucasian children, respectively.
- Non-Caucasian children from low SES areas experienced the shortest sleep opportunities.
Conclusions:
- Children's sleep behaviors are significantly influenced by social and cultural factors, not solely biological mechanisms.
- Disparities in sleep patterns exist across different genders, SES levels, and ethnicities in school-aged children.
- Recommendations for healthy sleep in children should consider these socio-cultural drivers to be effective and equitable.
Objectives:
Age-related changes in sleep behavior are well described in children, yet the effect of gender, socioeconomic status (SES), and ethnicity is less clear. These factors are important when developing culturally and socially appropriate guidelines for healthy sleep. The objective of our study was to examine the effects of age, gender, SES, and ethnicity on sleep patterns in school-aged children.
Methods:
A cross-sectional survey was conducted through primary schools in Adelaide, South Australia. Parents reported demographic information and sleep patterns for school and non-school days for 1845 children aged 5 to 10years.
Results:
48% of the cohort were boys (mean age, 7.7±1.7y), 85% were Caucasian, and there was an equal distribution across defined SES bands. Sleep duration reduced with age and was shorter on non-school than school nights as a result of later bedtimes. Boys, children from low SES areas, and non-Caucasian children reported shorter sleep times than girls, children from high SES areas, and Caucasian children, respectively. Non-Caucasian children from low SES areas reported the shortest sleep opportunity.
Conclusions:
The results from our study suggest that in addition to biological mechanisms, sleep behaviors are culturally and socially driven and should be considered when developing recommendations for healthy sleep in children.
