Compliance With the 24-h Movement Behaviours Guidelines Among Brazilian Toddlers.

The sample came from seven early childhood centres in one city in northeast Brazil, so it may not represent toddlers in other regions or countries. Screen time and night sleep were reported by parents, and centre naps were recorded by researchers, so these measures may be less accurate than direct measurement. The study included only typically developing toddlers who could walk independently, so it does not describe toddlers with mobility or developmental limitations. Accelerometer data were not used for sleep because valid sleep cutoff points were not available for hip placement in toddlers. The study is cross-sectional, so it reports current compliance and does not show change over time. No prior published study of Brazilian toddler 24-h compliance was available for direct comparison.

Do not read the high physical activity compliance as proof that toddlers were active at moderate or vigorous intensity. The guideline counted total activity, and the study reported that approximately 80% of total activity was light.
