Boiled coffee consumption and the risk of prostate cancer: Follow-up of 224,234 Norwegian men 20-69 years - Abstract

BACKGROUND: There is insufficient epidemiological evidence on the relationship between type of coffee and the risk of prostate cancer.

METHODS: The risk of prostate cancer by use of boiled vs not boiled coffee were assessed in a prospective study of 224,234 men 20-69 years. 5740 incident prostate cancers were identified.

RESULTS: With no coffee as reference group the hazard ratios of < 1-4, 5-8 and 9+ cups per day of boiled coffee only were 0.84 (0.73-0.96), 0.80 (0.70-0.92) and 0.66 (0.55-0.80), P-trend=0.00. The corresponding figures for not boiled coffee were 0.89 (0.80-0.99), 0.91 (0.81-1.02) and 0.86 (0.74-1.00), P-trend=0.22.

CONCLUSION: An inverse relationship between number of cups per day and the risk of prostate cancer was present only for the boiled coffee type.
