“…Few studies have examined adherence to the ‘5-2-1-0’ recommendations collectively and assessed predictors of attainment ( Foltz et al, 2011 , Kunin-Batson et al, 2015 , Rogers et al, 2013 , Haughton et al, 2016 , Gonzalez et al, 2015 , Iannotti and Wang, 2013 , Briefel et al, 2015 , Turer et al, 2013 ). Furthermore, there is a paucity of studies that have assessed the association of ‘5-2-1-0’ recommendations with BMI z-score or weight status in preschool-aged children ( Schrempft et al, 2015 , Gortmaker et al, 2015 ), which is important to consider given that 80% of children in this age group use screens daily ( Rideout et al, 2003 ). Of the studies examining adherence to the ‘5-2-1-0’ recommendations, most have relied on self-reported data ( Rogers et al, 2013 , Haughton et al, 2016 , Gonzalez et al, 2015 , Iannotti and Wang, 2013 , Briefel et al, 2015 ) and have focused on school aged children ( Kunin-Batson et al, 2015 , Rogers et al, 2013 , Haughton et al, 2016 , Gonzalez et al, 2015 ) or adolescents ( Foltz et al, 2011 , Haughton et al, 2016 , Iannotti and Wang, 2013 ) instead of preschoolers ( Briefel et al, 2015 , Turer et al, 2013 , Schrempft et al, 2015 ).…”
