“…Prior studies have evaluated various interventions to improve behaviors for obesity prevention such as school-based child obesity interventions (Wang et al, 2013, Waters et al, 2011, Oude Luttikhuis et al, 2009, Martin et al, 2014, Wyatt et al, 2013), family support (Epstein et al, 1990, Epstein et al, 1994, Kitzmann and Beech, 2006, Wrotniak et al, 2004, Drury et al, 2013, Epstein et al, 2014, Wilfley et al, 2007), peer support (McLean et al, 2003, Cohen et al, 1987, Jeffery et al, 1983, Osilla et al, 2012, Paul-Ebhohimhen and Avenell, 2009), competition/performance-based financial incentives (Martin et al, 2014, Wyatt et al, 2013, Drury et al, 2013, Jeffery et al, 1983, Volpp et al, 2008, Paul-Ebhohimhen and Avenell, 2008, You et al, 2012, Hersey et al, 2008, Hubbert et al, 2003, Sykes-Muskett et al, 2015, Mantzari et al, 2015, Purnell et al, 2014, Mayor, 2013, Mitchell et al, 2013, Burns et al, 2012, Kullgren et al, 2013, Crane et al, 2012, Finkelstein et al, 2013, Hunter et al, 2016, Ngo et al, 2014, Patel et al, 2016, Simpson et al, 2015, Finkelstein et al, 2016, Finkelstein et al, 2015, Hunter et al, 2015), donation to charity (Finkelstein et al, 2016, Finkelstein et al, 2015, Hunter et al, 2015), and a regulatory obesity policy in child care facilities (Wright et al, 2015). For instance, one study asked adults about their preferences for a hypothetical set of obesity prevention intervention incentives (You et al, 2012) which varied in the reward form, amount, and timing.…”
