Rethinking sustainability in childhood obesity prevention interventions: learning from South Australia's Obesity Prevention and Lifestyle (OPAL) Programme.

Increases in childhood obesity have occurred across a relatively short time-period, yet childhood obesity prevention is a longer-term game. Programmes have only identified population-level changes after 12 years of on-the-ground activity [Romon et al.]. Community stakeholders can impact the success of public health interventions [Ganter et al.; Lee et al.] and they have been identified as a critical success factor for programme sustainability [Schell et al.]. Qualitative research with stakeholders (n = 59) provides their insights and understandings of the sustainability of OPAL, a South Australian childhood obesity prevention programme. Stakeholders identified activities that they thought contributed to improved sustainability of action such as embedding obesity prevention into organizational policy and plans; and installation of infrastructure within communities to modify physical environments. In contrast, there was little appetite for sustaining OPAL or other formulations of a childhood obesity prevention programme. This research has implications for planning and implementation of community-based childhood obesity prevention initiatives when considering the balance of the portfolio of activities for implementation.
