Prostate cancer mortality among Catholic priests

Area of Science:

• Epidemiology
• Oncology

Background:

• Prostate cancer is a significant health concern.
• The role of lifestyle factors, such as celibacy, in cancer etiology requires further investigation.

Purpose of the Study:

• To investigate the potential association between celibate lifestyles and prostate cancer incidence.
• To analyze cancer mortality patterns among Roman Catholic clergymen.

Main Methods:

• Mortality data from 6,226 Roman Catholic clergymen in New York State (1965-1977) were analyzed.
• Death certificates of 1006 priests were reviewed, with 156 deaths attributed to malignant neoplasms.
• Observed prostate cancer deaths were compared to expected rates based on New York State white males.

Main Results:

• Clergymen exhibited 15% lower all-cause mortality and 30% lower cancer mortality compared to the general population.
• Twelve prostate cancer deaths were observed, significantly lower than the expected 19.8.
• Reduced mortality was also noted for lung, colorectal, and stomach cancers, but higher rates for melanoma and unspecified respiratory cancers.

Conclusions:

• Celibate lifestyles among Catholic clergymen are associated with significantly lower prostate cancer mortality.
• The findings suggest a protective effect of celibacy against prostate cancer, warranting further research into underlying mechanisms.
