Implementing a healthy food retail policy: A mixed-methods investigation of change in stakeholders' perspectives over time

AbstractObjectives:To investigate (i) changes in stakeholder commitment and (ii) perceptions of the purpose, challenges and benefits of healthy food and beverage provision in community sports settings during the stepwise implementation of a healthy beverage policy.Design:Convergent, parallel, mixed-methods design complemented (i) repeat semi-structured interviews with council stakeholders (n 17 interviews, n 6 interviewees), with (ii) repeat quantitative stakeholder surveys measuring Commitment to Organisational Change; (iii) weekly sales data examining health behaviour and revenue effects (15 months pre-intervention; 14 months post-intervention); (iv) customer exit surveys (n 458); and (v) periodic photographic audits of beverage availability. Interviews were analysed inductively. Stakeholder surveys, sales data, customer surveys and audits were analysed descriptively.Setting:Four local government-owned sports and recreation centres in Melbourne, Australia, completed a 3-month trial to increase the availability of healthy beverages and decrease the availability of unhealthy beverages in food outlets.Participants:Interviews were conducted with council managers and those involved in implementation (September 2016–October 2017). Customers were surveyed (September–October 2017).Results:Interviews and surveys indicated that stakeholders’ commitment to policies varied such that, over time, optimism that changing beverage availability could increase the healthiness of customers’ purchases became more widespread among interviewees. Stakeholder focus generally progressed from anticipatory concern to solutions-focused discussions. Sales, audit and customer survey data supported interview findings.Conclusions:We found a general increase in optimism regarding policy outcomes over time during the implementation of a healthy beverage policy. Stepwise trials should be further explored as an engagement tool within community retail settings.
