An end to outdoor marketing of gambling, alcohol and junk food is urgently needed to protect children from harm, according to new University of Otago-led research.
The research revealed that children in Aotearoa are exposed to seven gambling advertisements a day, half on shop fronts alone; 4.5 alcohol advertisements a day, a third of which are on shop fronts; and 27 junk food advertisements a day, a third of which are in outdoor public spaces. For every hour children were in public outdoor settings, they spent 70 per cent of that time in the street, 13 per cent in outdoor recreation settings and 13 per cent in outdoor sports settings.
The study involved 122 Wellington area 12-year-olds wearing body cameras for four days plus mapping analysis of the impact of marketing bans on children. The innovative Kids’Cam cameras took a photo every seven seconds, recording how often children were exposed to harmful product marketing as they went about their daily lives.
Senior author Professor Louise Signal, of the University of Otago, Wellington, says children are exposed to harmful marketing across many settings, and not just those conceived as “child places” such as playgrounds or around schools.
Marketing also clusters in harmful “hot spots” near city centres where stores and restaurants are common. There, children frequently encounter signs on streets and shopfronts marketing alcohol, gambling and junk food.
Billboards across the community also played a role.
“It was clear there were few settings children could escape these harmful marketing messages so comprehensive action is needed,” Professor Signal says.
Children were also more likely to see harmful product marketing around alcohol and gambling outlets, than near schools or in residential areas.
“This is not particularly surprising, given that these outlets typically market the harmful products they sell through shop fronts and street signs.
“Clearly, the current national level industry self-regulation of marketing through the Advertising Standards Authority fails to protect our children,” Professor Signal says.
The World Health Organization has called for government regulation of such marketing to protect children’s rights.
“Vaping marketing was banned in Aotearoa in 2021 through national legislation, and tobacco marketing has been banned for years. Children in this study reveal the urgent need for such a ban on alcohol, gambling and junk food marketing as well,” she says.
The study shows that if marketing of alcohol, gambling and junk food was banned within 400m of a bus stop, children’s exposure would be reduced by 86 per cent, followed by bans in residential areas by 59 per cent and by 42 per cent around schools. While larger banning areas unsurprisingly led to higher reduction rates, even a ban of 100m around bus stops led to a 27 per cent reduction.
Aside from tobacco and vaping in Aotearoa, there are other examples of effective harmful product marketing bans here and around the world, Professor Signal says.
“There is a ban on alcohol marketing on public transport in Auckland, junk food marketing on public transport in the Wellington region and junk food marketing on public transport and roads in Queensland. Alcohol advertising is banned in public outdoor settings in Estonia, Ireland, and Norway. The cities of São Paulo and Grenoble have successfully introduced bans on all outdoor marketing.”
She says newly elected councils have a real opportunity to remove harmful product marketing from their communities and a role in reducing the number of alcohol and gambling outlets in their communities to reduce associated marketing.
“These children have revealed how urgent local and central government action is on this matter.”
The study was funded by the Cancer Society, and its Medical Director Dr Kate Gregory says the results should shock policymakers into action.
“Junk food and alcohol cause many harms including cancer. Gambling takes money from the poor which could be spent on healthy food and other essentials,” Dr Gregory says.
“Marketing promotes harmful products as part of everyday life, drives consumption and maximises profits at the expense of the health of our children.”
The study builds on previous Kids’Cam research using data collected in 2014/15.
