Lee also regretted that the researchers didn't check health traits such as weight, body-mass index or blood pressure along with the length of the patients' telomeres.
"For example, if the participants in the intervention group with longer telomere length had lower blood pressure, it would have been far more interesting," Lee said. "Even though it may not have been significant statistically due to small sample size, it would have been informative."
The study was not intended to gauge whether lifestyle changes slowed progression of prostate cancer.
