Abstract
BackgroundTobacco use, alcohol use, and sugar-sweetened beverage consumption are each associated with increased cancer-risk. Psychological trauma is a common experience and a key driver of these behaviours among adults. The primary aim of this study is to evaluate the effect of trauma-informed yoga, drumming, and psychoeducation compared to control on tobacco use, alcohol use, and sugar-sweetened beverage consumption among community-based adults. Secondary aims are to evaluate the effect of these interventions compared to control on psychological and physiological stress symptomology, social connection, and coping behaviour.MethodsRecruitment for this single-blinded randomized trial began in April 2019 in the Faculty of Health Sciences at the University of Lethbridge. Adults who consumed tobacco, alcohol, or sugar-sweetened beverages in the past month and live in Lethbridge, Alberta are being recruited using ads placed in public spaces. Participants are randomly allocated to a 12-session group yoga class, 12-session group drumming class, a 12-session psychoeducation class, or control. Participants attend an appointment in-person to fill out an online questionnaire package, provide a saliva sample, and complete physical measures pre-intervention, and 1-month and 6-months post-intervention.DiscussionThis study provides a unique opportunity to compare the impacts of two trauma-informed body-based interventions to psychoeducation and control for cancer-risk behaviour among community-based adults. The findings can be used to develop trauma-informed group interventions to reduce cancer-risk behaviour in general populations. Results are expected in 2022.Trial registrationThis trial was registered with ClinicalTrials.govISRCTN15583681 on 22 August 2019 (retrospectively registered).
Highlights
Tobacco use, alcohol use, and sugar-sweetened beverage consumption are each associated with increased cancer-risk
Statistical analysis For prediction of cancer-risk behaviour at 1 and 6 months post-intervention, participants will be included in the analysis if they have completed 50% of the intervention they are assigned to and have completed followup data collection for the specific time point
Social trauma is a common experience and may be a key driver of cancer-risk behaviours, within Indigenous populations given the legacy of colonization
Summary
Alcohol use, and sugar-sweetened beverage consumption are each associated with increased cancer-risk. The primary aim of this study is to evaluate the effect of trauma-informed yoga, drumming, and psychoeducation compared to control on tobacco use, alcohol use, and sugar-sweetened beverage consumption among community-based adults. Secondary aims are to evaluate the effect of these interventions compared to control on psychological and physiological stress symptomology, social connection, and coping behaviour. Well established cancer-risk behaviours include smoking and alcohol use. The habitual consumption of sugar-sweetened beverages is an emerging risk factor for cancer associated with the increased incidence of pancreatic, gallbladder and biliary tract cancer; with cancer reoccurrence and mortality generally; and with important risk factors for cancer (e.g., type 2 diabetes, obesity) [13,14,15,16,17]
