title: Raw shellfish consumption in California: the 1992 California Behavioral Risk Factor Survey.
abstract: We used the 1992 California Behavioral Risk Factor Surveillance System to study the prevalence of raw shellfish consumption in California and the demographic and behavioral characteristics of raw shellfish consumers. We used the logistic regression analysis of the weighted survey data with PC SAS and SUDAAN to adjust for the effects of age and gender. Twenty-three percent of the respondents in the survey reported that they ate raw shellfish; one third of these reported eating raw shellfish once a month. Higher prevalences of raw shellfish consumption were reported by men, persons 18-49 years old, those with income above $25,000 and education beyond high school than by women, individuals older than 49 years, and those with an income of $25,000 or less per year and 12 or fewer years of school. A higher percentage of persons with liver disease, stomach surgery, and a history of chronic alcohol drinking reported consumption of raw shellfish than did individuals without liver disease, previous stomach surgery, or a history of alcohol abuse. After adjustment for gender and age, those who reported acute (P < .01) and chronic (P < .01) drinking and driving while intoxicated (P < .01) were more likely to report consumption of raw shellfish. Two variables (lack of seat belt usage [P = 2] and cigarette smoking [P = .13]) were not significantly associated statistically with raw shellfish consumption.
