DESCRIPTION (provided by applicant): We propose a wave seven telephone diagnostic interview follow-up of the MOAFTS (Missouri Adolescent Female Twin Study) young cohorts A and B (target N=2100 twin interviews), and for some participants who have not yet provided samples, saliva sample collection (target N=840) for genotyping for zygosity confirmation. MOAFTS is a prospective study of a birth cohort of female like-sex twin pairs (N=370 African- American pairs, N=1999 European/Other Ancestry pairs) identified from birth records and first assessed in adolescence, at median age 16. Goals of the project are to characterize, in a broadly representative general population female twin cohort, gene-environment interplay in alcoholism and associated substance use disorders, focusing on (i) parental alcoholism and its associated twin offspring environmental risk-exposures and outcomes, and (ii) the development and course of female drinking and alcohol-related problems, as well as other substance use and problems (particularly tobacco use and dependence), through adolescence into young adulthood, emphasizing precursors/mediators and moderators of genetic and environmental effects on both onset of and recovery from problems. In the most recent data-collection, interviews were completed with approximately 3500 respondents at ages 21-30. Wave seven will provide a further follow-up of alcohol and other substance use and problems, and proximal environmental exposures, so that most twins are through their period of greatest risk for onset of alcohol problems, and the sample will be old enough to be informative about the predictors of remission versus persistence of alcohol problems and heavy drinking (target N=700 assessed at age 30, N=1400 assessed at age 28/N=100 new dependence cases). Our research is motivated by the concern that the genetic transmission of risks of alcohol and other substance use disorders frequently occurs in the context of high-risk environmental exposures commonly associated with parental alcoholism - including interpersonal conflict and divorce or never-cohabitation, step-parent presence, childhood assaultive trauma, family socioeconomic disadvantage - risks that need not be reduced by the departure of an alcoholic parent from the home. Through completion of the wave seven data-collection and data-analyses, our goals are to understand how these early environmental exposures, in combination with genetic effects, influence onset and course of heavy drinking and alcohol problems, either directly, or through effects on timing of onset of alcohol use and on comorbid substance use, and effects on subsequent adult role changes of the twins (early or delayed parenting; relationship formation, conflict and dissolution; education completion, employment, and adult peer relationships); and to identify other variables (history of childhood or adolescent-onset psychopathology, other substance use disorders) that may mediate or moderate these relationships. Current understanding of the genetic epidemiology of female alcohol use disorders is based largely on either retrospective or underpowered studies - a gap that the MOAFTS cohort will help to fill. PUBLIC HEALTH RELEVANCE: Alcohol misuse by young women is associated with significant impairments including difficulties in forming and maintaining stable romantic relationships, delayed reproduction, and impaired parenting, as well as risks associated with hazardous use. Better understanding of risk-mechanisms leading to the onset and persistence versus remission of female alcohol misuse in adolescence and young adulthood will have important implications for motivating and better targeting prevention and intervention efforts for young women and, in some cases, mitigating risks to their children.

描述(由申请人提供)：我们建议对MOAFTS(密苏里州青少年女性双胞胎研究)年轻队列A和B进行第七波电话诊断访谈(目标N=2100对双胞胎访谈)，对于一些尚未提供样本的参与者，收集唾液样本(目标N=840)进行基因分型以确认合子。MOAFTS是对出生记录中的女性同性双胞胎(N=370对非洲裔美国人，N=1999对欧洲/其他血统双胞胎)的出生队列进行的前瞻性研究，首次在青春期进行评估，年龄中值为16岁。该项目的目标是在具有广泛代表性的普通女性双胞胎队列中描述酒精中毒和相关物质使用障碍的基因-环境相互作用，重点是(I)父母酗酒及其相关的双胞胎后代环境风险暴露和后果，(Ii)女性饮酒和酒精相关问题的发展和过程，以及其他物质使用和问题(特别是烟草使用和依赖)，从青春期到青壮年，强调遗传和环境对问题的发生和恢复的影响的先兆/中介者和调节者。在最新的数据收集中，对大约3500名年龄在21-30岁的受访者进行了采访。第七波将对酒精和其他物质的使用和问题以及最近的环境暴露进行进一步的跟踪，以便大多数双胞胎都经历了出现酒精问题的最大风险时期，样本将足够大，可以提供关于酒精问题缓解与持续和酗酒的预测因素的信息(目标N=700在30岁评估，N=1400在28岁评估/N=100新的依赖病例)。我们研究的动机是，酒精和其他物质使用障碍风险的基因传递经常发生在通常与父母酗酒有关的高风险环境暴露的背景下--包括人际冲突和离婚或从未同居、继父母的存在、童年攻击性创伤、家庭社会经济劣势--这些风险不需要通过酗酒的父母离开家而降低。通过完成波七的数据收集和数据分析，我们的目标是了解这些早期环境暴露如何与遗传效应相结合，直接或通过对开始饮酒的时间和共病物质使用的影响，以及对双胞胎随后的成人角色变化的影响(早期或延迟的父母养育；关系的形成、冲突和解体；教育完成、就业和成年同伴关系)；以及确定可能调节或调节这些关系的其他变量(儿童或青少年发病的精神病理学史，其他物质使用障碍)。目前对女性酒精使用障碍的遗传流行病学的理解主要是基于回顾研究或力量不足的研究--MOAFTS队列将有助于填补这一空白。公共卫生相关性：年轻女性滥用酒精会造成严重的损害，包括难以形成和维持稳定的恋爱关系、生育延迟、育儿能力受损，以及与危险使用相关的风险。更好地了解导致女性在青春期和成年期滥用酒精开始和持续而不是缓解的风险机制，将对激励和更好地针对年轻女性的预防和干预工作产生重要影响，在某些情况下，还可以减少对其子女的风险。
