Objective: To assess preferred sources of information for seeking physical activity (PA), and how PA information seeking may contribute to participation in a campus PA program. Participants: Students attending a large, Western Canadian university between April 2015 and April 2018. Methods: Secondary analysis of an annual campus-wide survey. Results: Students sought PA information for general health. Females sought information about weight loss for appearances; males sought information for muscle gain for appearance. Internet and friends were primary sources of PA information. Regression analysis indicated females 2.49 (95% CI 1.98-3.13), domestic students 2.86, 95% CI (2.04-4.02), and first year students 24.88, 95% CI (18.12-34.17) were most likely to participate in a campus PA program. Only health reasons significantly contributed to participation 1.42, 95% CI (1.06-1.89). Conclusions: Emerging adults attending university may benefit from PA promotion that makes use of their preferred information sources.
