Date	Event	Description
21 October 2011	New search has been performed	Searches have been run for the update period (July 2007 to October 2011); 30 new project accounts have been identified and are included in the updated review
21 October 2011	New citation required but conclusions have not changed	This update has not impacted the conclusions and recommendations of the original review. One change to note is that the physical health status outcome blood cholesterol level (mg/dL) is no longer statistically significant
29 April 2010	Amended	Change in scope: 3 new relevance criteria have been added and applied to all included studies: (1) randomised controlled trials; (2) interventions implemented a minimum of 12 weeks; and (3) interventions aimed at the general population. This has resulted in exclusion from the update of 12 studies from the original review: 9 because they were not RCTs (Alexandrov 1988; Berenson 1993; Graf 2005; Klepp 1994; Lionis 1991; Manios 1999; Marcus 1987; Plotnikoff 1999; Sallis 1997); 2 because the intervention was shorter than 12 weeks (Eliakim 1996; Fardy 1996); and 1 because the study sample included overweight or obese children only (Carrel 2005a)
19 January 2010	Amended	Review author ‐ RL LaRocca ‐ has been added
21 May 2008	Amended	Review has been converted to new review format
