ReviewEarly childhood physical activity, sedentary behaviors and psychosocial well-being: A systematic review

•The first review to comprehensively evaluate early childhood PA/SB with psychosocial well-being•Each psychosocial well-being indicator was investigated in a minimal number of studies.•Multiple and disparate indicators of PA/SB were used.•No studies of strong methodological quality nor any RCTs were identified.•PA/SB during early childhood shows no clear association with psychosocial well-being

ObjectivesLittle is known about how health behaviors such as physical activity (PA) and sedentary behaviors (SB) may be associated with psychosocial well-being during the crucial early childhood period. The aim of this study was to undertake a systematic review of associations between PA, SB and psychosocial well-being during early childhood.MethodsIn February 2013, MEDLINE, PsycINFO, SPORTDiscus and Embase electronic databases were searched. Inclusion criteria were: 1. peer-reviewed publication since 1980 in English; 2. children aged birth-5 years; 3. PA or SB measured during early childhood; 4. an indicator of child psychosocial well-being; and 5. association between PA/SB and psychosocial well-being reported. Studies could be observational or interventions. Data were extracted by one author and entered into a standardized form in February and March 2013.Results19 studies were identified: four examined PA, 13 examined SB and two examined PA and SB. No interventions met the inclusion criteria; all included studies were observational. In total, 21 indicators of psychosocial well-being were examined, 13 only once with the remaining eight reported in more than one study. Some dose-response evidence was identified suggesting that PA is positively, and SB inversely, associated with psychosocial well-being.ConclusionsToo few studies exist to draw conclusions regarding associations. Future high-quality cohort and intervention studies are warranted particularly investigating dose-response associations.
