In this research, GPS and food purchasing data of approximately 450 young adult participants (16-30 years old), collected for one week across five Canadian cities, are used to explicitly address the links between activity patterns, the food retail environment, and food shopping behaviours for an understudied population. With the GPS data, a time-weighted kernel density estimate surface is used to generate a unique activity space-based food environment, with an emphasis on places where more time is spent, for each participant. Then, statistical models are computed to answer two primary questions: First, how do personal characteristics (e.g., age, employment), self-rated health, and city of residence relate to the number of food retailers accessible in young adults’ activity spaces? Second, how do the previous factors and an activity space-based food environment affect where young adults make food purchases? The results show that various personal characteristics (e.g. age, sex, being a household food shopper) and city of residence are significantly associated with different levels of exposure to various types of food retailers, as well as that food shopping behaviours are significantly associated with personal characteristics, self-reported health, and participants’ activity spaces.
