项目摘要
Abstract
The primary pathway of alcohol metabolism involves two main enzymes, alcohol and aldehyde dehydrogenase.
Several genes (ALDH2, ADH1B) that encode these enzymes have variant alleles that alter the rate of metabolism
and result in heightened and protracted exposure to acetaldehyde, a known carcinogen. The variant ALDH2*2
allele is associated with the flushing response (i.e., “Asian glow”) and is found almost exclusively in individuals
of east Asian descent (560+ million people worldwide). Although possession of variant ALDH2 and ADH1B
alleles are protective against heavy drinking and alcohol use disorders, for those who do drink, these variants
also are independently and synergistically associated with striking elevations in risk for several cancers, including
esophageal and head and neck cancers. This cancer risk, however, is not widely known outside of the research
community. The premise of this study is that we can affect early drinking trajectories through personalized
communication about these cancer risks. We specifically target 360 college students of northeast Asian descent,
a high-risk group as college is a time of escalating alcohol consumption. It is also a context in which a risk-
communications intervention, if successful, could be readily scaled-up. We will compare risk communication with
and without personalized genotype feedback by randomizing participants into one of three groups: 1) a group
receiving information about cancer risk associated with alcohol consumption and alcohol metabolism genetic
deficiencies that manifest as flushing, plus personalized flushing (i.e. phenotype) feedback (PHEN), 2) a group
receiving the PHEN information plus personalized genotype feedback on ALDH2 and ADH1B (PHEN+GENE),
or 3) a comparison attention CONTROL group receiving duplicate information from the AlcoholEdu® for College
mandatory online training about alcohol risk already completed by all incoming students. In Aim 1, we will develop
the brief web-based interventions. In Aim 2, we will test our hypotheses that a) informing drinkers of risk will
lower alcohol consumption levels and use of “flush cures”, and b) informing non-drinkers will reduce or delay
drinking onset. We also will test if genotype feedback results in a greater attenuation of drinking than general
risk information and phenotype feedback only, and if the impact is stronger in those at greater risk based on their
phenotype and/or genotypes. Finally, we will test the possible mediating roles of perceived cancer risk, cancer
prevention self-efficacy, and alcohol expectancies as underlying mechanisms of behavior change. Aim 3 will
determine study effect sizes within the latent growth modeling framework we will employ, including for our
mediation analyses. These analyses will establish the feasibility of implementing these interventions and setting
the stage for a larger multisite study. Results of this work may inform intervention/prevention efforts on how to
optimally target personalized feedback protocols for high-risk college samples and scale these at a national level.
摘要
酒精代谢的主要途径包括酒精和乙醛脱氢酶两种主要的酶。
编码这些酶的几个基因(ALDH2、ADH1B)具有改变新陈代谢速度的不同等位基因
并导致对乙醛的高度和长期接触,乙醛是一种已知的致癌物质。变种ALDH2*2
等位基因与脸红反应(即“亚洲红晕”)有关,几乎只在个体中发现。
东亚血统(全球5.6亿以上人口)。虽然拥有变异体ALDH2和ADH1B
等位基因对酗酒和酒精使用障碍有保护作用,对于饮酒者来说,这些变体
也独立和协同地与几种癌症风险的显著上升有关,包括
食道癌和头颈癌。然而,这种癌症风险在研究之外并不广为人知。

没有通过将参与者随机分成三组之一的个性化的基因反馈:1)一组
接收与饮酒和酒精代谢基因相关的癌症风险信息
表现为刷新的缺陷,加上个性化刷新(即表型)反馈(Phen),2)一组
接收phen信息加上关于ALDH2和ADH1B(phen+基因)的个性化基因反馈,
或3)比较注意控制组,接受来自AlcoholEdu®for College的重复信息
所有即将入学的学生已经完成了关于酒精风险的强制性在线培训。在目标1中,我们将开发
简短的基于网络的干预。在目标2中,我们将测试我们的假设:a)告知饮酒者风险将
较低的饮酒量和“潮红疗法”的使用,以及b)通知不饮酒者将减少或推迟
饮酒发作。我们还将测试基因反馈是否会导致饮酒的减少程度比一般情况下更大
