Purpose: We used patients input and behaviour change theory to design a video series on the Too Fit To Fracture physical activity recommendations. The aim of this work is to describe series development and report on uptake. Methods: Focus groups and interviews were conducted with older adults across Ontario, with purposeful sampling by gender and urban/rural location. Two researchers coded data and identified emerging themes, categorized as representing capability, opportunity and motivation in accordance with the Behaviour Change Wheel. Themes informed a 13-part video series featuring patient stories, answers to common questions, and functions: modeling, persuasion, training, incentivisation, education and enablement. Videos featured cases of variable age and gender, and addressed noted barriers or patient questions. Media communications were the primary delivery method. Uptake over 7 months was estimated as views in total and by region. Results: Since their release in November 2015, videos were shared by the Canadian Society for Exercise Physiology, Osteoporosis Canada, American Society for Bone and Mineral Research and the International Osteoporosis Foundation, and in traditional and social media. Videos were viewed 20,800 times in 86 countries. Audiences were primarily in Canada (16898 views, 81% of total) and the United States (2060 views, 10% of total) and other English-speaking countries (744 views, 4% of total). Average duration of views in English-speaking countries was 78% compared to 60% elsewhere. Within Canada, rural residents accounted for 22% of the viewership, slightly above the proportion of rural Canadians (19%). Nearly half of views were within the month of release when promotion was active. Another spike came after traditional media articles about the work of one of the authors and cited the videos. Conclusions: Partnering with knowledge users to create patient-centred, theory-informed, educational tools and delivery strategies resulted in broad uptake.
