Table 6). For example, the US studies included participants of ethnicities—such as African American, Hispanic/Latino, American Indian and Native Alaskan—that are uncommon in the Australian target population and that potentially have prevalence rates for specific behaviours. Studies in which these ethnicities are dominant (Gilreath et al., 2013, and Harpaz- Rotem et al., 2006, 2009) or where ethnicity was unreported (Weber, 2005) were less generalisable to the Australian context.
