Abstract
ISSUE ADDRESSED
The pervasive promotion of energy-dense, nutrient-poor food and drinks undermines efforts by adolescents and their parent/carers to maintain a nutritious diet during a crucial developmental period. This study examined the association between awareness of food and drink advertisements and adolescents' dietary behaviours and intake.
METHODS
A sample of Australian secondary students aged 12-17 years (N = 8763) self-reported their awareness of food and drink advertisements across seven settings, whether they had tried a new product or asked a parent/carer to purchase a product they had seen advertised, and their consumption of various unhealthy food and drink types. Analyses used multilevel mixed-effects generalised linear models adjusted for school-level clustering, socio-demographic factors and television viewing.
RESULTS
Students with higher advertising awareness were more likely to have tried a new product they had seen advertised (adjusted prevalence ratio [APR] = 1.62, 95% CI = 1.51-1.73, p < .001) and asked their parent/carer to buy an advertised product (APR = 1.62, 95% CI = 1.51-1.73, p < .001) at least once in the past month. As advertising awareness increased, so too did students' likelihood of reporting these dietary behaviours. A high unhealthy food intake was more commonly reported among students with higher advertising awareness (APR = 1.45, 95% CI = 1.32-1.58, p < .001), as was a high unhealthy drink intake (APR = 1.29, 95% CI = 1.18-1.42, p < .001).
CONCLUSIONS
Australian adolescents are vulnerable to the persuasive effects of food and drink marketing. SO WHAT?: Greater restrictions on the way the food and drink industry can market their products to adolescents are needed to better support them in developing and maintaining positive dietary behaviours.
