“…When it comes to parental influence through parents' own PA habits, a recent review (Xu, Wen, & Rissel, 2015) showed that parents' encouragement, support and role modelling could result in higher levels of their children's PA. Nevertheless, to the authors' knowledge, few studies have investigated objectively and simultaneously measured PA for preschool-aged children and their parents, showing positive but mainly weak associations between parental and child PA (Jago et al, 2014;Moore et al, 1991;Ruiz, Gesell, Buchowski, Lambert, & Barkin, 2011;Taylor et al, 2009). Regarding sedentary time, earlier studies using objective measures in preschool-aged children have found that seasonality plays a limited role in sedentary time with lower sedentary time in summer and fall compared with spring (Fisher et al, 2005); no association with sedentary time and gender exists (Vanderloo & Tucker, 2015); nor association with socio-economic status and sedentary time (Kelly et al, 2006).…”
