*NS=no significant difference between children with siblings and only children;Favourssiblings = results found favoured the presence of siblings (ie, increased LPA or MVPAor CPMor decreased SB);Does not favoursiblings=results found did not favour the presence of siblings (ie, decreased LPA or MVPA or CPMor increased SB);M-NS/F-favourssiblings = NS result for boy’s physical activity outcomes, Favours siblings for girl’s physical activity outcomes;M-favourssiblings/F-NS =favours sibling result for boy’s physical activity outcomes, NS result for girl’s physical activity outcomes;Mixed results =results that favoured siblings (less SB) and results that did not favour siblings (more SB) were found, Favours onlyoldersiblings=results indicated that only older siblings improved physical activity outcomes; Favours only 2+ =results indicated that having greater than two siblings improved physical activity outcomes.
CPM,counts per minute;LPA,light physical activity;MVPA,moderate-to-vigorous physical activity;SB,sedentary behaviour;SED,sedentary behaviour.
