Abstract

AIMS: The aims of this study were to: quantify the levels and predictors of physical activity in prostate cancer survivors on androgen-deprivation therapy (ADT); gain some insight into the effect of physical activity on the quality of life of prostate cancer survivors on ADT; and compare the quality of life of prostate cancer survivors on ADT with matched controls.

METHODS: A sample of 84 prostate cancer survivors on ADT were recruited from a register held by the Auckland District Health Board. Participants were mailed a collection of self-report surveys probing quality of life, physical activity and determinants of physical activity.

RESULT: Less than half the prostate cancer sample were categorised as physically active, and there was no relationship between physical activity and age, PSA levels, or time on ADT. Compared to a matched control group the sample had lower scores for global quality of life, as well as on the physical and environmental quality of life domains. Results also showed that those prostate cancer survivors classified as active had higher levels of quality of life on average than those classified as insufficiently active. Attitude towards physical activity was the dominant predictor of the intention to be physically active, while perceived behavioural control was the dominant predictor of actual behaviour.

CONCLUSIONS: Our findings describe a positive relationship between physical activity and quality of life in men with prostate cancer currently undergoing ADT. However, only half the sample was physically active, indicating that physical activity interventions aimed at prostate cancer survivors are of utility. Our data suggests targeting both attitudes and factors related to the ability to perform physical activity will be fruitful approaches.
