The authors examined the association between the intake of different dairy products and the risk of bladder cancer in 120,852 men and women aged 55-69 years participating in the Netherlands Cohort Study on Diet and Cancer. Dairy product intake was assessed in 1986 by using a 150-item food frequency questionnaire. The cohort was followed for 16.3 years, and 1,549 incident cases of bladder cancer were analyzed. Cox proportional hazards analysis was applied with a case-cohort approach by using the follow-up data of a random subcohort (n=5,000). Multivariate hazard ratio estimates comparing the highest with the lowest quintile of total dairy intake were 1.01 (95% confidence interval (CI) : 0.81,1.27 ; Ptrend=0.68). A statistically significant association for fermented milk products was found only for the second quintile (median, 12 g/day) (hazard ratio=0.71,95% CI : 0.56,0.91). Compared with nonconsumers, women with 25-75 g/day of butter consumption had a hazard ratio of 1.61 (95% CI : 1.03,2.50 ; Ptrend
