Stress, hostility, and disease parameters of benign prostatic hyperplasia.

Objective: Psychological factors such as stress are known to influence activity in the sympathetic nervous system and hypothalamic-pituitary-gonadal axis, systems that in turn have been implicated in the development of benign prostatic hyperplasia (BPH). Associations between psychological stress and prostate function have not been directly examined. The objective of this study was to examine associations among stress, hostility, and BPH disease parameters.

Methods: Eighty-three men diagnosed with BPH completed self-report and interview measures of stress and hostility followed by measures of urologic function.

Results: Higher lifetime stress was associated with lower prostate volumes and residual urine volumes (p's < .05). By contrast, high recent stress and hostility were associated with greater residual urine (p's < .05). Stress and hostility were not associated with self-report ratings of urologic symptoms.

Conclusions: Stress and hostility were associated with objective measures of urologic functioning among men with BPH. Results highlight the need for increased attention in research and clinical settings toward associations between psychological factors and urologic disease.
