Longitudinal associations between sleep and weight status in infants and toddlers
Authors' conclusion
Increasing sleep duration can improve weight status outcomes in very young children who have low physical activity levels.
Study context
- Population
- Children aged 6–24 months, assessed at ≈6, 12, 18 and 24 months
- Participants
- 116 children
- Outcome
- Weight-for-length z-score in relation to average and within-person changes in sleep duration
- Follow-up
- ≈6, 12, 18 and 24 months
Methodological detailsactigraphy-measured sleep, linear mixed models
- Actigraphy-measured sleep
- Linear mixed models
Main finding
As reported in the abstract
- At time points where children slept longer at night than their own average, weight-for-length z-score was lower
- Relationship attenuated by physical activity levels
Observational data: associations, not effects.
