在流行病学研究中，没有标准化的方法来评估酒精消费。本研究的主要目的是比较三种广泛使用的评估酒精消费的方法，根据发病率和死亡率指标确定的高风险饮酒和危害的流行率估计。方法采用受试者内设计比较定量频率、分级频率和每周饮酒回忆测量。数据包括加拿大安大略省3961名成年居民的代表性样本，他们在1990-1994年间参加了一项多波横断面调查。交叉表法、Spearman相关性和基于患病率的疾病成本研究的标准方法被使用。结果分级频率测量一致地得出了高风险饮酒和危害流行率的较高估计。所有指标都存在差异，但最明显的是有害饮酒，即男性每天平均摄入60克纯酒精，女性每天平均摄入40克纯酒精。对有害饮酒的患病率估计，分级频率比每周饮酒测量高出近5倍，分级频率比定量频率测量高出近3倍。结论在今后的流行病学研究中，应考虑不同酒精摄入指标的特点。
Background There are no standardized ways to assess alcohol consumption in epidemiological studies. The main objective of the present study was to compare three widely used methods for assessing alcohol consumption with respect to resulting prevalence estimates for high risk drinking and harm as defined by morbidity and mortality indicators.Methods A within-subjects design was used to compare a quantity frequency, a graduated frequency, and a weekly drinking recall measure. Data consisted of a representative sample of 3961 adult residents of the province of Ontario, Canada, who participated in a multi-wave cross-sectional survey between 1990-1994. Cross-tabulation, Spearman correlation, and standard methodologies for prevalence-based cost-of-illness studies were used.Results The graduated frequency measure consistently yielded higher estimates of the prevalences of high risk drinking and harm. Differences were marked on all indicators, but were most pronounced for harmful drinking as defined by consuming an average of >60 g pure alcohol per day for males, and >40 g per day for females. Prevalence estimates of harmful drinking were almost five times higher for graduated frequency versus weekly drinking measures, and almost three times higher for graduated frequency versus quantity frequency measures.Conclusions The characteristics of different measures of alcohol consumption should be considered in future research in epidemiology.
