Insights
Sufficient sleep duration and healthy sleep patterns are linked to healthy weight in children. Ensuring adequate sleep, especially on weekends, may help prevent childhood obesity.
Area of Science:
- Pediatric Health
- Obesity Research
- Sleep Science
Background:
- Childhood obesity is a growing concern linked to lifestyle changes and insufficient sleep.
- Adequate sleep is crucial for children's growth, development, and overall well-being.
Purpose of the Study:
- To investigate the association between sleep duration and weight status in children.
- To examine sleep patterns on weekdays and weekends in relation to childhood obesity.
Main Methods:
- A study involving Greek students (2014-2016) classified weight status using International Obesity Task Force guidelines.
- Sleep duration was self-reported for weekdays and weekends.
- Classification and regression tree analysis identified sleep patterns and their relation to weight status.
Main Results:
- An inverse association was found between average sleep duration (weekdays and weekends) and the likelihood of being overweight or obese.
- This association was stronger on weekends.
- Children with shorter weekday sleep but longer weekend sleep showed a reduced likelihood of being overweight/obese.
Conclusions:
- Sleep duration and patterns are significantly associated with childhood weight status.
- Interventions promoting adequate sleep duration and healthy sleep patterns are recommended for children's development.
- Educating parents on the importance of sleep for healthy child development is crucial.
Study Objectives:
Sleep is an essential normal function for children's growth and development, but over the years, lifestyle changes have resulted in insufficient sleep, a factor that may be associated with increased childhood obesity. The aim of this study was to evaluate the association between sleep duration and sleep patterns separately on weekdays and weekends regarding children's weight status.
Methods:
This study was conducted among Greek students (55.1% girls) in 2014-2016. Children's weight status was classified according to the International Obesity Task Force tables and guidelines. Sleep duration was determined based on the sleep and wake time that children reported, separately for weekdays and weekends. Classification and regression tree analysis was used to derive sleep patterns and evaluate their relation to children's weight status.
Results:
Multiadjusted analysis revealed an inverse association between average duration of sleep on weekdays and weekends with the likelihood of being overweight/obese (odds ratio per 1 hour 0.82; 95% confidence interval, 0.73-0.92). This was more prominent on weekends than on weekdays. Children who had lower duration on weekdays, but catch-up sleep duration on weekends, were 2% (95% confidence interval, 0.97-0.99) less likely to be overweight/obese compared to those children having both less or increased sleep duration on weekdays and weekends.
Conclusions:
Sleep duration and sleep patterns seem to be associated with childhood weight status. Interventions should be developed to educate parents on the importance of an adequate sleep duration and healthy sleep patterns for their children's healthy development.
