A low level of response (LR) to alcohol characterizes groups at high risk for alcoholism and predicts future heavier drinking and alcohol-related problems. Because LR might change with increasing age and years of drinking, there is a need to measure this phenotype as early as possible in the drinking career.
Data were generated from 1,106 12- to 13-year-old subjects in the Avon Longitudinal Study of Parents and Children (ALSPAC). Information about alcohol and other substance use and problems was obtained using a structured interview, and LR from the Self-Rating of the Effects of Alcohol (SRE) questionnaire.
Drinking was reported by 80 (7.3% of all subjects) boys and girls. Boys comprised 62.5% of the sample; the mean (SD) age of subjects was 12.9 (0.16) years. Among those 80 drinkers, alcohol had been consumed on an average of 5.4 occasions over the prior 6 months, the average maximum drinks ever imbibed was about 3.3, and 23.8% had any of 26 possible alcohol-related problems. In this group, 36.3% had smoked cigarettes, and 12.5% had used marijuana. The First 5 SRE score among drinkers correlated with the maximum number of drinks consumed at one time at .61 (p < .001), the number of alcohol problems at .25 (p < .01) and the frequency of drinking at .29 (p < .01). When considered along with smoking and marijuana histories, sex and weight, the SRE score contributed significantly to the prediction of maximum drinks per occasion (beta = .60, p < .001) and drinking frequency (beta = .24, p < .05), with a trend (beta = .17, p = .08) for alcohol problems.
These results support the conclusion that a low LR to alcohol correlates well with the maximum number of drinks consumed even early in the drinking career among individuals for whom acquired tolerance or other factors were unlikely to have explained the relationship.
对酒精的低反应水平(LR)是酒精中毒高危人群的特征之一,并可预测未来饮酒量增加及与酒精相关的问题。由于LR可能会随着年龄增长和饮酒年限的增加而变化,因此有必要在饮酒生涯中尽早测量这一表型。
数据来自雅芳亲子纵向研究(ALSPAC)中的1106名12至13岁的受试者。通过结构化访谈以及酒精影响自评(SRE)问卷获取有关酒精及其他物质使用和问题的信息。
报告有饮酒行为的男孩和女孩共80名(占所有受试者的7.3%)。男孩占样本的62.5%;受试者的平均(标准差)年龄为12.9(0.16)岁。在这80名饮酒者中,过去6个月平均饮酒5.4次,平均最大饮酒量约为3.3杯,23.8%出现过26种可能与酒精相关问题中的任何一种。在该组中,36.3%的人吸烟,12.5%的人使用过大麻。饮酒者的前5项SRE得分与一次饮酒的最大杯数的相关性为0.61(p < 0.001),与酒精问题数量的相关性为0.25(p < 0.01),与饮酒频率的相关性为0.29(p < 0.01)。当结合吸烟史、大麻使用史、性别和体重考虑时,SRE得分对每次最大饮酒量(β = 0.60,p < 0.001)和饮酒频率(β = 0.24, p < 0.05)的预测有显著贡献,对酒精问题有一定趋势(β = 0.17,p = 0.08)。
这些结果支持以下结论:即使在饮酒生涯早期,对于那些后天耐受性或其他因素不太可能解释这种关系的个体而言,对酒精的低LR与最大饮酒量密切相关。
