Australia: the healthiest country by 2020
National Preventative Health Strategy – the roadmap for action
Effective and coordinated social marketing campaigns are needed to increase physical activity levels and improve eating habits. These campaigns should inform, encourage and motivate individuals and families to make changes to their lifestyles.
The best evidence on the effectiveness of social marketing campaigns indicates that long-term, well-funded, sustained campaigns underpinned by qualitative research are necessary to achieve behaviour change. Compelling evidence from areas such as tobacco control, drink driving/road safety, immunisation, sun protection and HIV/AIDS, as well as the commercial sector, shows that appropriately targeted investment in social marketing can provide health and economic gains across populations.[125-128] Lessons from these campaigns are transferable to obesity management and prevention.
The Go for 2&5 campaign in Western Australia, conducted between 2002 and 2005, comprised a comprehensive range of strategies including mass media advertising, public relations events, a website, point-of-sale promotions, and school and community activities. Over the campaign period, awareness of dietary fruit and vegetable recommendations increased among the target audience of adults. In addition, there was an increase in population consumption of 0.2 servings for fruit and 0.6 servings for vegetables per day.[129]
Queensland Health has invested $4.4 million over 4.5 years (2005–10) in a statewide Go for 2&5 social marketing campaign strategy. Prior to the implementation of the campaign in 2005, adult consumption of fruit and vegetables was 3.5 serves per day, around half the recommended intake. Phase one increased fruit and vegetable consumption by an average 0.4 serves per person per day in the target age group in January–March 2006. Ongoing campaign tracking has shown a peak increase of 1.1 serves per person per day. Data suggests that recent price increases in fruit and vegetables and long off-air periods have eroded some of the gains in fruit and vegetable consumption. Final evaluation data will be available in mid-2010.[130]
The eventual evaluation of the Australian Government’s Measure Up campaign will provide valuable evidence in refining and targeting future communication strategies. Building on these campaigns at the state and territory and national level is essential to an effective approach.
Results demonstrate the importance of extended periods of campaign implementation to sustain accompanying knowledge, intentions and behaviour changes. The importance of televised media campaigns broadcast at sufficient exposure levels over relatively frequent intervals in achieving population behaviour change has been clearly demonstrated for tobacco in decreasing population smoking levels. This research highlights the need for such campaigns to be ongoing to sustain population-level change.[131]
A significant challenge to the promotion of healthy eating and physical activity behaviours is the fact that advertising for energy-dense nutrient-poor (EDNP) products generally promotes behaviours that compete with public health recommendations and strengthen potentially negative or challenging behaviours.[132, 133] Even during a major national nutrition campaign, exposure to healthy fresh food advertising is likely to be much lower than that for unhealthy food, unless investment in social marketing is significantly increased. Data collection on food advertising undertaken in 2005, at the same time as the Go for 2&5 fruit and vegetable promotion was screened, showed fruit and vegetable advertisements to comprise 4.6% of total food advertisements during children’s viewing periods (as defined by the Children’s Television Standards). During the same period, high-fat, high-sugar food advertising comprised 81.5% of total food advertisements; the observed differences have significant implications for the impact of nutrition promotion campaigns.[134]
