This paper reports on cutting edge research that used wearable cameras to study children's exposure to food and beverage marketing. The research aimed to determine the frequency, duration and nature of children's exposure to food and beverage marketing in their everyday lives. 169 children (mean age = 12.6y; SD = 0.46; 89 girls, 80 boys) recruited from 16 randomly selected schools in Wellington, New Zealand wore cameras for four days that took pictures automatically at 10s intervals, along with a GPS recorder. Data was collected from July 2014 to June 2015. Bespoke computer software was used to code the images and produce outputs for statistical analysis. Images were annotated for setting, marketing media, and product/brand category. GPS and image data were linked for spatial analysis of patterns of exposure. Criteria for nutrient assessment will be discussed and the study protocol outlined. This study generated approximately 1.5 million images, most of which could be coded. Wearable cameras enable the objective quantification of children's exposure to junk food marketing. It is possible to use wearable cameras to study food marketing, and likely other aspects of the obesogenic environment we live in, such as physical activity, sedentary behaviour and use of green spaces.
