背景：自我报告已成为急性和初级保健人群酒精评估的锚。该研究的目的是确定住院非依赖性饮酒者意外受伤后自我报告的饮酒量的有效性。方法：非酒精依赖的受试者18岁及以上的意外伤害（n = 209）被纳入研究，并接受采访，如果他们有一个入院血液酒精浓度（BAC）大于或等于10毫克/分升（0.01 g/dl）或有问题饮酒史的阳性筛查。自我报告的标准饮料的数量，饮酒开始的时间，性别和体重被用来计算估计的血液酒精浓度（EBAC），然后比较入院BAG.Results：我们有数据来计算EBAC的141 209名受试者。BAC阳性（大于或等于10 mg/dl）的7名男性和无女性否认饮酒。在我们有数据计算EBAC并承认饮酒的134名受试者中，平均BAC为147.06 mg/dl，平均EBAC为68.66 mg/dl。女性（n = 30）的平均BAC为149.53 mg/dl，平均EBAC为114.67 mg/dl;男性（n = 104）的平均BAC为146.35 mg/dl，平均EBAC为55.38 mg/dl。所有受试者（n = 134）的实验室BAC和EBAC之间的斯皮尔曼rho为0.461（p < 0.001），女性（n = 30）为0.275（NS），男性（n = 104）为0.532（p < 0.001）。对于女性和男性，分别进行多元回归分析，以预测BAC使用的重量和报告的饮料数量。对于女性，体重和饮酒次数占实验室BAC方差的3%[r = 0.181，F（2，47）= 0.797，p = NS]。相反，对于男性，这些相同的预测因子解释了34%的方差[r = 0.585，F（2，135）= 35.203，p < 0.001]。结论：大多数非依赖性意外伤害患者在受伤前承认饮酒。受伤后，女性和男性报告饮酒的模式不同，男性更经常少报，但报告更准确，女性在自我报告中更随意。
Background: Self-report has become an anchor for alcohol assessment in the acute and primary care populations. The purpose of the study was to determine the validity of self-reported alcohol consumption after unintentional injuries iri hospitalized, nondependent drinkers.Methods: Non-alcohol-dependent subjects 18 years of age and older with unintentional injuries (n = 209) were enrolled in the study and were interviewed if they had either an admitting blood alcohol concentration (BAC) greater than or equal to 10 mg/dl (0.01 g/dl) or a positive screen for a history of problem drinking. The self-reported number of standard drinks, time that drinking commenced, sex, and weight were used to calculate estimated blood alcohol concentration (EBAC), which was then compared to the admission BAG.Results: We had data to calculate the EBAC on 141 of the 209 subjects. Seven men and no women with positive (greater than or equal to 10 mg/dl) BAC denied drinking. Of the 134 subjects for whom we had data to calculate EBAC and who acknowledged drinking, mean BAC was 147.06 mg/dl and mean EBAC was 68.66 mg/dl. For women (n = 30), mean BAC was 149.53 mg/dl and mean EBAC was 114.67 mg/dl; for men (n = 104), mean BAC was 146.35 mg/dl and mean EBAC was 55.38 mg/dl. The Spearman's rho between laboratory BAC and EBAC was 0.461 (p < 0.001) for all subjects (n = 134), 0.275 (NS) for women (n = 30), and 0.532 (p < 0.001) for men (n = 104). For women and men separately, multiple regression analyses were performed to predict BAC by using weight and reported number of drinks. For women, weight and number of drinks accounted for 3% of the variance in laboratory BAC [r = 0.181, F(2,47) = 0.797, p = NS]. In contrast, for men these same predictors accounted for 34% of the variance [r = 0.585, F(2,135) = 35.203,p < 0.001).Conclusions: Most nondependent patients with unintentional injury acknowledged drinking before injury. After injury, women and men have different patterns of reporting their drinking, with men more frequently underreporting but reporting more accurately and women more random in their self-reports.
