This study compares reported beer, wine and liquor intake from a dietary quantity-frequency questionnaire and a 16-day diet diary kept by the same respondents in the 1984-85 University of Michigan Food Frequency Study. The study subjects were 228 black and white men and women, aged 24-51 years. On the two methods, the reported mean ethanol intake derived from each beverage, mean frequency of intake of each beverage and mean quantity for each beverage were similar. The relative rankings of individuals by the amount of ethanol for each beverage were also similar. The methods agreed less well on whether a particular beverage was ever consumed. The absolute amount of ethanol from each beverage agreed more closely between methods than did the percent of ethanol from each beverage. Results were similar for each race-sex subgroup. These findings suggest that analyses should use the reported amount of ethanol from each beverage, rather than converting to percentages or classifying according to the most used beverage. The good general agreement in the types and amounts of alcoholic beverages reported promotes some confidence in the relative validity of data from these two dietary methods for describing moderate alcohol intake in the general population.
本研究比较了在1984 - 1985年密歇根大学食物频率研究中，同一批受访者通过饮食数量频率问卷和16天饮食日记所报告的啤酒、葡萄酒和烈酒摄入量。研究对象为228名年龄在24至51岁之间的黑人和白人男性及女性。在这两种方法中，每种饮料所报告的平均乙醇摄入量、每种饮料的平均摄入频率以及每种饮料的平均量都相似。按每种饮料中乙醇含量对个体进行的相对排名也相似。对于是否饮用过某种特定饮料，两种方法的一致性较差。两种方法之间，每种饮料中乙醇的绝对量比每种饮料中乙醇的百分比更为接近。每个种族 - 性别亚组的结果相似。这些发现表明，分析应采用每种饮料所报告的乙醇量，而非换算为百分比或根据最常饮用的饮料进行分类。所报告的酒精饮料类型和量的总体良好一致性，提升了对这两种饮食方法用于描述一般人群适度饮酒情况数据的相对有效性的信心。
