abstract="BACKGROUND AND AIMS: Questions about drinking &quot; yesterday&quot; have been used to correct under-reporting of typical alcohol consumption in surveys. We use this method to explore patterns of over- and under-reporting of drinking quantity and frequency by population sub-groups in four countries. <br><br>DESIGN: Multivariate linear regression analyses comparing estimates of typical quantity and frequency of alcohol consumption with and without adjustments using the Yesterday method. Setting and participants Survey respondents in Australia (n = 26,648), Canada (n = 43,370), USA (n = 7,969) and England (n = 8,610). MEASUREMENTS: Estimates of typical drinking quantities and frequencies over the past year plus quantity of alcohol consumed the previous day. <br><br>FINDINGS: Typical frequency was underestimated by less frequent drinkers in each country. For example, after adjustment for design effects and age, Australian males self reporting drinking &quot;less than once a month&quot; were estimated to have in fact drunk an average of 14.70 (±0.59) days in the past year compared with the standard assumption of 6 days (t = 50.5, p < 0.001). Drinking quantity &quot; yesterday&quot; was not significantly different overall from self-reported typical quantities over the past year in Canada, USA and England but slightly lower in Australia (e.g. 2.66 vs 3.04 drinks, t = 20.4, p < 0.01 for women). <br><br>CONCLUSIONS: People who describe themselves as less frequent drinkers appear substantially to under-report their drinking frequency, but country and sub-group specific corrections can be estimated. Detailed questions using the Yesterday method can correct under-reporting of quantity of drinking.<br><br>This article is protected by copyright. All rights reserved.<p /> <p>Language: en</p>",
