Wine consumption and epithelial ovarian cancer.

We examined the relationship between consumption of specific alcoholic beverages, including wine, beer, and liquor, and risk of epithelial ovarian cancer using data from the Swedish Mammography Cohort, a population-based prospective study of 61,084 women ages 38 to 76 years at enrollment in 1987 to 1990. Information on consumption of alcoholic beverages was obtained through a mailed food frequency questionnaire. The Pearson correlation coefficients for the responses to the questionnaire for consumption of wine, beer, and liquor compared with four 1-week diet records (validation study among a subsample of 129 women from the cohort) were 0.8, 0.7, and 0.5, respectively. We used Cox proportional hazards models to estimate multivariate rate ratios (RR) and 95% confidence intervals (95% CI) while adjusting for age, body mass index, educational level, parity, oral contraceptive use, and intakes of energy and lactose (consumption of wine, beer, and liquor was mutually adjusted).
