In efforts to reduce current public health concern of overweight and obesity
in children and adolescents, actions are being made to promote physical activ-
ity (PA) and reduce sedentary time in youth (Nilsson et al, 2009). To conduct
efficient interventions, it is important to understand a broad range of corre-
lates and determinants of PA (Sallis et al, 1999; Nilsson et al, 2009; Stanley et al,
2012) including socio-demographic, environmental and individual behaviour-
al factors. Most-researched correlates are gender, age, socio-economic sta-
tus, parental and peer influences (Craggs et al, 2011). Due to awareness of the
health benefits of regular PA, many interventions have tried to increase chil-
dren’s PA levels in different environments with varied levels of success (Stan-
ley et al, 2012). In-school setting has long been defined as the ideal environ-
ment for PA promotion interventions. Recent reviews generally showed that
school-based PA promotion was effective at increasing PA during school, al-
though effect on out-of-school and overall PA is less clear (Kriemler et al, 2011).
In meta-analysis of physical activity interventions on objectively measured lev-
els of PA, interventions had only a small effect on children’s overall activity lev-
els: about 4 minutes more walking or running per day (Metcalf et al, 2012). This
lecture will focus on reviewing correlates of PA and effects of interventions for
increasing physical activity and reducing sedentary time in children and adoles-
cents.
