Leukocyte Telomere Length: Diet and Exercise Trial


  • Org Study ID: STUDY19070303
  • Secondary ID: N/A
  • NCT ID: NCT03286699
  • Sponsor: University of Pittsburgh


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.
