The correlates of after-school sedentary behavior among XXXX aged 5-18 years: a systematic review.

@entity1 @entity146
BACKGROUND: @entity1 and adolescents spend a large proportion of the after-school period in @entity146 ( @entity146 ). Identifying context-specific correlates is important for informing strategies to reduce these behaviors. This paper systematically reviews the correlates of @entity1 's and adolescents' after-school @entity146 . METHODS: A computerized literature search was performed in October 2015 for peer-reviewed original research journal articles published in English before October 2015. Eligibility criteria included: 1) sample aged 5-18 years; 2) quantified the amount of @entity146 or component of this that the @entity1 /adolescents were performing after school; 3) a measure of @entity146 as the dependent outcome; and 4) the association between potential correlates and after-school @entity146 . RESULTS: Data were synthesized in October 2015. Thirty-one studies met the eligibility criteria: 22 studies among @entity1 ( <=12  years), six among adolescents (>12  years), two had a combined sample of @entity1 and adolescents and one cohort followed @entity1 from childhood to adolescence. Findings were separated by after-school location i.e. after-school programs (n   =   4 studies) and unidentified locations (n   =   27). There was insufficient evidence to draw conclusions on all but two of the 58 potential correlates: sex and age. Among @entity1 at unidentified locations there was a null association between sex (male) and overall after-school @entity146 , a null association between sex (male) and after-school TV viewing, a positive association between age and overall after-school @entity146 and an inconsistent association between age and after-school TV viewing. No correlates of after-school sedentary behaviour while at after-school programs were identified. CONCLUSIONS: Only two correlates have been investigated frequently enough to determine an overall association; neither correlate is modifiable. Due to the lack of consistent investigation of potential correlates, further evidence is required to accurately identify potential intervention targets. PROSPERO REGISTRATION NUMBER: CRD42014009180.
