Cluster 1: meet both the PA and SED guidelines, signifying that daily MVPA time was ≥60 min while daily screen time was < 2 h

Cluster 2: meet either PA or SED guidelines, signifying that daily MVPA time was ≥60 min while daily screen time was ≥2 h, or daily MVPA time was < 60 min while daily screen time was < 2 h

Cluster 3: meet neither PA nor SED guideline, signifying that daily MVPA time < 60 min while daily screen time was ≥2 h
