Light walking helps prostate patients post treatment

Strolling associated with less depression and fatigue

Gentle walking after prostate treatment helps reduce the damaging side effects of treatment. 

According to findings from Chicago, non-vigorous walking for three hours per week helps patients improve fatigue, depression and body weight issues that affect many men post-treatment. 

"If you walk even more briskly, for only 90 minutes a week, you could also see similar benefits in these areas,” said Siobhan Phillips, lead author of the study and assistant professor in the department of preventive medicine at Northwestern University Feinberg School of Medicine. 

The paper*, published this week in the Journal of Cancer Survivorship: Research and Practice, is one of the first to investigate how different intensities and types of physical activity affect the health-related quality of life of men after prostate cancer treatment.

Phillips used data from the Health Professionals Follow-up Study, which includes self-reported data since 1986 on 51,529 men in health professions and is based at the Harvard T.H. Chan School of Public Health. She focused on prostate cancer survivors who were diagnosed with non-advanced disease prior to 2008 and responded to a health-related quality of life (HRQOL) questionnaire.

Common HRQOL symptoms included urinary and bowel problems, sexual function issues, fatigue, depression, increased body weight and erectile dysfunction.

The men reported the average time spent during a week walking to work or for exercise as well as time spent jogging, running, cycling, swimming and playing sports. They also reported their usual outdoor walking pace as easy, average, brisk or very brisk.

After controlling for pre-diagnosis physical activity and sedentary time, the findings indicate that higher duration of total, non-vigorous and walking activity -- especially brisk walking -- were associated with better hormone/vitality functioning (affecting fatigue, depression and body weight) but not with bowel, urinary, or sexual functioning.

Those who are able to walk should be encouraged to start an easy walking routine or engage in other non-vigorous activities soon after a prostate cancer diagnosis, Phillips said. The benefits could help manage symptoms such as fatigue, depression and body weight - and improve overall health.

"Cancer survivors have a higher risk of other conditions, such as cardiovascular disease," Phillips added, "Walking may also potentially increase survival and impact their quality of life by preventing the onset of those other conditions.”
