Conditions

Bladder Cancer, Colorectal Adenoma, Telomere Shortening

Brief summary

The goal of the research is to provide a first critical test of the novel scientific idea that a combined diet and exercise intervention may ameliorate shortening of leukocyte telomere length (LTL) in individuals with histories of successfully treated non-metastatic bladder cancer (BC) or colorectal adenoma (CRA) compared to a diet only intervention.

Interventions

BEHAVIORALDietary Intervention

The behavioral weight loss intervention strategies will not be limited to, self-monitoring, goal setting, problem solving, mastery skills, social support, and relapse prevention. Participants will receive a standard behavioral weight control program, delivered on a one-on-one basis. They will attend in-person sessions (\ 30-45 minutes) with time to: distribute intervention materials, interact with the participant, identify participants that need additional support, and conduct the intervention. Each in-person visit focuses on a specific behavioral topic related to weight loss to address eating behaviors. Subjects will also participate in phone calls with the interventionist (\ 10 minutes). Depending on the week, subjects will have between 10 and 45 minutes of total intervention contact.

BEHAVIORALPhysical Activity Intervention

The behavioral weight loss intervention strategies will not be limited to, self-monitoring, goal setting, problem solving, mastery skills, social support, and relapse prevention. Participants will receive a standard behavioral weight control program, delivered on a one-on-one basis. They will attend in-person sessions (\ 30-45 minutes) with time to: distribute intervention materials, interact with the participant, identify participants that need additional support, and conduct the intervention. Each in-person visit focuses on a specific behavioral topic related to weight loss to address physical activity behaviors. Subjects will also participate in phone calls with the interventionist (\ 10 minutes). Depending on the week, subjects will have 10 to 45 minutes of total intervention contact.
