Diet and exercise are important for the wellbeing of people with cancer and their family caregivers. Unfortunately, little is known about their behaviors over time or factors that may influence their engagement in these behaviors. This exploratory study examined the influence of chronic conditions, symptom distress, and perceived social support on exercise and diet behaviors of patients with advanced cancer and their caregivers using the actor-partner interdependence mediation model (APIMeM) and interdependence theory as guiding frameworks.
