Wearable activity technology and action-planning (WATAAP) to promote physical activity in cancer survivors: Randomised controlled trial protocol

Background/Objective: Colorectal and gynecologic cancer survivors are at cardiovascular risk due to comorbidities and sedentary behaviour, warranting a feasible intervention to increase physical activity. The Health Action Process Approach (HAPA) is a promising theoretical frame-work for health behaviour change, and wearable physical activity trackers offer a novel means of self-monitoring physical activity for cancer survivors. Method: Sixty-eight survivors of colorectal and gynecologic cancer will be randomised into 12- week intervention and control groups. Intervention group participants will receive: a Fitbit AltaTM to monitor physical activity, HAPA-based group sessions, booklet, and support phone-call. Participants in the control group will only receive the HAPA-based booklet. Physical activity (using accelerometers), blood pressure, BMI, and HAPA constructs will be assessed at baseline, 12-weeks (post-intervention) and 24-weeks (follow-up). Data analysis will use the Group x Time interaction from a General Linear Mixed Model analysis. Conclusions: Physical activity interventions that are acceptable and have robust theoretical underpinnings show promise for improving the health of cancer survivors

Wearable activity technology and action-planning (WATAAP) to promote physical activity in cancer survivors: Randomised controlled trial protocol

FUNDAMENTOS/OBJETIVO: Los sobrevivientes de cáncer colorrectal y ginecológico corren riesgo cardiovascular debido a las comorbilidades y al comportamiento sedentario, lo que justifica una intervención factible para aumentar la actividad física. El Enfoque del Proceso de Acción Sanitaria (HAPA) es un marco teórico prometedor para el cambio de comportamiento en materia de salud, y los rastreadores de actividad física que se pueden llevar puestos ofrecen un medio novedoso de autocontrol de la actividad física para los supervivientes de cáncer. MÉTODO: Sesenta y ocho sobrevivientes de cáncer colorrectal y ginecológico serán asignados al azar a grupos de intervención y control de 12 semanas. Los participantes del grupo de intervención recibirán: un Fitbit AltaTM para monitorear la actividad física, sesiones de grupo basadas en HAPA, un folleto y una llamada telefónica de apoyo. Los participantes del grupo de control sólo recibirán el folleto basado en HAPA. La actividad física (utilizando acelerómetros), la presión sanguínea, el IMC y las construcciones HAPA se evaluarán en la línea de base, a las 12 semanas (después de la intervención) y a las 24 semanas (seguimiento). El análisis de los datos utilizará la interacción Grupo x Tiempo de un análisis de Modelo Mixto Lineal General. CONCLUSIONES: Las intervenciones de actividad física que son aceptables y que tienen sólidos fundamentos teóricos son prometedoras para mejorar la salud de los sobrevivientes de cáncer.BACKGROUND/OBJECTIVE: Colorectal and gynecologic cancer survivors are at cardiovascular risk due to comorbidities and sedentary behaviour, warranting a feasible intervention to increase physical activity.
