Feasibility of a Habit-Based Intervention to Reduce Sedentary Behaviour in Cancer Survivors

Summary

Cancer and its treatments are associated with long-term side effects including lowered physical strength and quality of life. Decreasing sedentary behaviour improves health outcomes in cancer survivors. Habit-based programs aimed at lowering sedentary behaviour have been successful in decreasing sedentary behaviour in other populations. However, limited clinical trials aimed at lowering sedentary behaviour have recruited cancer survivors, and none are exclusively based on Habit Theory. The primary goal of this clinical trial is to test the feasibility of an 8-week, habit-based program to lower sedentary behaviour in cancer survivors. Sedentary behaviour refers to low-energy activities performed during waking hours in a seated, reclined or laid down position. Secondarily, this clinical trial aims to examine changes in sedentary behaviour, physical strength, habit, and quality of life. Enrolled participants will be assigned to a sedentary behaviour or active control group. The sedentary behaviour group will receive 8 weekly sheets consisting of tips recommending to lower sedentary behaviour. Tips will be individualized to participants' lifestyles, and will consider their cancer-specific and other physical limitations. Participants in the sedentary behaviour group will also meet with the researcher once a week for a check-in session for more individualized tips and progressions. The active control group will receive the Canadian 24-hour Movement Guidelines, and a handout highlighting the benefits of lowering sedentary behaviour. Both groups will be provided with wearable activity monitors (Fitbits).
