“…The most frequent child correlates reported were sex and age. Strong associations (7/8 studies) with children's physical activity in ECE services were found for age (i.e., younger children were more active than older children) (Bell et al, 2015; Connelly et al, 2021; Henderson et al, 2015; Mazzucca et al, 2018; Olesen et al, 2015; Sando, 2019a; Terrón‐Pérez et al, 2019) and sex (in 12 out of 14 studies, boys were more active than girls) (Connelly et al, 2021; Copeland et al, 2016; Díaz‐Quesada et al, 2022; Henderson et al, 2015; Lahuerta‐Contell et al, 2021; Määttä et al, 2020; Määttä, Lehto, et al, 2019; Ryu et al, 2021; Soini et al, 2016; Terrón‐Pérez et al, 2019; Tonge et al, 2020; Webster et al, 2019). No strong positive associations were identified with child variables and children's sedentary behaviour in ECE services.…”
