目标：人口调查通常会低估大约40%-50%的酒精消耗量。研究人员经常对调查数据进行统一调整，以加权估计，使其与基于销售或税收数据的消费衡量标准相匹配。这项研究通过比较澳大利亚两个主要人口调查的数据，探索了自我报告的消费数据中是否存在不同的低估比率。方法：这项研究比较了国家毒品战略家庭调查(NDSHS，使用分级频率问题，覆盖率=55%)和国际酒精控制研究(IAC，使用地点内饮料特定问题，覆盖率=86%)对人口亚群消费的调查估计。分析检查了基于年龄和性别的亚组以及基于重度饮酒率的亚组。结果：分级频率问题(NDSHS)与饮品特定地点问题(IAC)相比低估了33%的消费。年轻男性(40%)和中年女性(49%)的低估程度更高，年轻女性(15%)和老年女性(NDSHS估计比IAC高19%)的低估程度较低。很少饮酒或根本不饮酒的受访者比饮酒者(43%比22%)更(按比例)低估了自己的饮酒量。结论：在使用标准分级频率问题的人口调查中，酒精消费的低估在人口统计或基于消费的人口亚群中并不是一致的。需要更有力的方法来调整调查数据，以匹配消费的客观衡量标准。
Objective: Population surveys typically produce underestimates of alcohol consumption of approximately 40%-50%. Researchers often undertake a uniform adjustment of survey data to weight estimates such that they match measures of consumption based on sales or tax data. This study explored whether there are differential rates of underestimation in self-reported consumption data by comparing data from two major population surveys in Australia. Method: The study compared survey estimates of consumption for population subgroups from the National Drug Strategy Household Survey (NDSHS, using graduated-frequency questions, coverage = 55%) and the Australian arm of the International Alcohol Control Study (IAC, using within-location beverage-specific questions, coverage = 86%). Analyses examined age- and sex-based subgroups as well as subgroups based on rates of heavy episodic drinking. Results: The graduated-frequency questions (NDSHS) underestimated consumption by 33% compared with the beverage-specific within-location questions (IAC). Underestimates were more marked for young males (40%) and middle-aged females (49%) and less marked for young females (15%) and older females (NDSHS estimates were 19% higher than IAC). Respondents who engaged infrequently or not at all in heavy episodic drinking underestimated their consumption by more (proportionally) than those who did (43% vs. 22%). Conclusions: Underreporting of alcohol consumption in population surveys using standard graduated-frequency questions is not uniform across either demographic or consumption-based subgroups of the population. More robust approaches to adjusting survey data to match objective measures of consumption are required.
