Issue Addressed: The LiveLighter ^® healthy weight and lifestyle social marketing campaign, developed in Western Australia, employs graphic advertising to communicate negative health effects of overweight and motivate behaviour change. This study extends prior evidence of the effectiveness of the LiveLighter ^® campaign by evaluating its implementation in a new jurisdiction.
Methods: A controlled cohort design was employed in intervention (Vic) and comparison states (SA), with and without campaign exposure. Population surveys conducted at baseline (BL) (n = 1000 each state), had 75% retention at follow-up (FU) (Vic: n = 715; SA: n = 787).
Results: Total campaign awareness was moderate (61.5%). Exposed respondents indicated the campaign was "believable" (91.0%), made a strong argument for reducing weight (87.3%), made them "stop and think" (70.1%), motivated action to reach/stay a healthy weight (59.1%) and was "relevant" (55.6%). The proportion of respondents indicating "toxic fat build up" was a health consequence of overweight increased significantly from BL to FU in Vic and to a lesser extent in SA (Vic:55.7% vs 75.9%; SA:58.1% vs 62.6%, interaction P < .001). The proportion indicating cancer is a health consequence of overweight increased significantly from BL to FU in Vic, but not in SA (Vic:77.1% vs 83.4%; SA:77.8% vs 78.1%, interaction P < .05).
Conclusions: This study extends the evidence base for the LiveLighter ^® campaign. Sustained campaign activity with clear behavioural recommendations is required to translate improved knowledge into behaviour change.
So What: Evidence-based mass media campaigns can positively impact health behaviours to address the unsustainable increasing burdens of unhealthy weight, dietary risk and inadequate physical activity. A National Obesity Campaign is needed and LiveLighter ^® is a ready-made, relevant Australian resource.
