Abstract: | Objective: To examine the relation between fruits and vegetables, carotenoids, folate, and vitamins A, C, E and the risk of bladder
cancer in a prospective study of women
Methods: A total of 237 incident bladder cancer cases were documented during 20 years of follow-up among 88,796 women enrolled in
the Nurses’ Health Study. Dietary intake was assessed by food-frequency questionnaires every two to four years and incident
diagnosis of bladder cancer was ascertained every two years. Cox proportional hazard models were used to estimate incidence
rate ratios (RR) and 95% confidence intervals (CI) for bladder cancer risk, adjusting for age, pack-years of smoking, current
smoking, and total caloric intake.
Results: Consumption of total fruits and vegetables was not associated with bladder cancer risk (RR = 1.08, 95% CI = 0.70–1.65, for
> 5.5 compared to < 2.5 servings per day). Similarly, dietary intakes of carotenoids, folate, and vitamins A, C, E, were not
related to bladder cancer risk. No association was observed between supplemental intake of multivitamins, vitamins A, C, E
and bladder cancer risk.
Conclusions: We did not observe any association for fruit and vegetable consumption or vitamin intake and bladder cancer risk among women. |
