“…The evaluation of such interventions covered a broad range of school-based strategies, including obesity prevention programs (Xu et al, 2015), peer-mentoring about physical activity (Tymms et al, 2016), lessons about active transport in a driving license course (Verhoeven et al, 2016), and a variety of initiatives aiming to encourage active commuting with children (e.g., cycle training, school travel plan, Safe Routes to School). Many of them nonetheless reported no significant effect of the implemented measures on increasing moderate-to-vigorous physical activity (Harrington et al, 2018;Sayers et al, 2012;Tymms et al, 2016) or promoting walking or cycling to school (McMinn et al, 2012;Østergaard et al, 2015;Teixeira et al, 2019), even when large-scale policy changes were considered (Sirard et al, 2015). The lack of evidence of the interventions' impact is reported predominantly among older children (aged 11 and above), and no difference in effect across gender and socio-economic position has been identified (Love et al, 2019).…”
