Diet, obesity, and risk of fatal prostate cancer

Findings described in this report are for 6,763 white male Seventh-day Adventists who completed a dietary questionnaire in 1960. Between 1960 and 1980 mortality data were collected on cohort members. Overweight men had a significantly higher risk of fatal prostate cancer than men near their desirable weight. The predicted relative risk of fatal prostate cancer was 2.5 for overweight men. Suggestive positive associations were also seen between fatal prostate cancer and the consumption of milk, cheese, eggs, and meat. There was an orderly dose-response between each of the four animal products and risk. The predicted relative risk of fatal prostate cancer was 3.6 for those who heavily consumed all four animal products. The results of this study and others suggest that animal product consumption and obesity may be risk factors for fatal prostate cancer.
