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.
我们利用1992年加利福尼亚行为危险因素监测系统，研究了加利福尼亚州生食贝类的流行情况以及生食贝类消费者的人口统计学和行为特征。我们使用PC SAS和SUDAAN对加权调查数据进行逻辑回归分析，以调整年龄和性别的影响。调查中23%的受访者表示他们食用生食贝类；其中三分之一的人报告每月食用一次生食贝类。据报告，男性、18至49岁的人、收入超过25,000美元且受过高中以上教育的人，生食贝类的比例高于女性、49岁以上的人、年收入25,000美元或以下且受教育年限为12年或更少的人。有肝病、胃部手术史和慢性饮酒史的人报告食用生食贝类的比例高于没有肝病、既往胃部手术或酗酒史的人。在调整性别和年龄后，报告有急性（P <.01）和慢性（P <.01）醉酒驾驶以及酒后驾车（P <.01）的人更有可能报告食用生食贝类。两个变量（未系安全带[P = 0.02]和吸烟[P = 0.13]）与食用生食贝类在统计学上无显著关联。
