Background
• Prostate cancer is the most common type of cancer in men (~3000 new cases/year in NZ—about 10% are Māori). Close to 180 new patients are in Dunedin.
• Treatment for localized prostate cancer includes prostatectomy or radiation therapy.
• A common treatment for systemic prostate cancer is androgen deprivation therapy (ADT).
• Over 40% of prostate cancer patients would be on ADT at some point in their life (Meng et al., 2002).

ADT side effects
Due to the loss of androgens, patients on ADT experience many side effects including:
• Sarcopenic obesity (weight gain as fat and loss of muscle mass).
• Fatigue
(Saylor & Smith, 2009)

Exercise
Exercise can alleviate some ADT side effects, including fatigue and risks of cardiovascular events
Current recommendation for cancer patients:
• 150 minutes of moderate-intensity aerobic exercise
• Resistance training at least 2 days per week
*The recommendation is outlined by the Canadian Society for Exercise Physiology and the American College of Sports Medicine. (Segal et al. 2017. Curr Oncol 24(1):40-46.)

Research Question
How does exercise level affect sleep and sexual parameters of prostate cancer patients?
![Page 7: Sleep Assessment in Prostate Cancer Patients and Their ...](https://reader034.fdocuments.net/reader034/viewer/2022042907/6269ecfcfa54047c27213d48/html5/thumbnails/7.jpg)
• 45 minute online survey completed by prostate cancer patients
• Survey was posted by prostate cancer or cancer organizations internationally.
• Exercise levels were measured by the Godin-Shepard leisure-time physical activity questionnaire- (Score≥24 = physically active)
• Sleep quality is assessed by Insomnia Severity Index (ISI)
• Sexual parameters are assessed by the Arizona Sexual Experiences Scale (ASEX).
*There are other data collected, but they won’t be discussed here.

• 58.45% had at least one university degree.
• 83.1% Caucasian
Prostate cancer treatment
• 59.2% had received prostatectomy

ADT Side Effects
The proportion of patients having
insomnia between the two groups are
similar.
Patients on ADT are more likely to have
no sexual activity than patients who
are not on ADT (P < 0.001).

Insomnia symptom- early waking
* ] Physically active patients on ADT have less problems with waking up too early than those who are
less physically active.

Physically active patients on ADT have better sexual function than patients on ADT who are non-physically
active. [Further analyses found beneficial exercise effects on sex drive, orgasm satisfaction and sexual frequency.]

Limitation
• Small sample size
• Most are Caucasian
• Well-educated
• Partnered
• Data are based on self-report
• Types of exercises are not standardized
Conclusion• Physical activity may have beneficial effects on sleep and sexual function for patients
who are on ADT.
