项目摘要

DESCRIPTION (provided by applicant): The goal of this research is to support public health efforts to reduce problems associated with alcohol use among men and women ages 50 and older. Heavy drinking increases morbidity and early mortality, but moderate drinking offers health benefits to many older adults by reducing risk for certain types of heart disease. It is well-established that many older adults drink regularly and that alcohol problems can develop late in life, but few studies have examined how drinking changes over time in this heterogeneous group. This longitudinal study will identify and describe alcohol use trajectories among older adults using four extant datasets from nationally representative cohorts including the Health and Retirement Study (HRS), the National Longitudinal Survey (NLS) of Mature Women, the NLS Young Women, and the Study of Assets and Health Dynamics among the Oldest Old (AHEAD). Members of the Young Women cohort entered their 6th decade of life during our study interval (1995-2004). The NLS Older Men and Young Men cohorts lack suitable alcohol data. Using four cohorts expands the age range of interest, increases the number of covariates to be considered, and supports replication analyses among women. All cohorts provided alcohol data on 5 occasions from 1995 to 2004 using two sets of comparable questions. Alcohol use trajectories will be identified and characterized with methods that have previously yielded new insights on drinking behaviors among adolescents and young adults. Latent class growth analysis (semi-parametric group based modeling) and growth mixture models will integrate person-centered quantitative methods with traditional variable-centered approaches. Consistent with an accumulation of risk conceptual model, covariates to be tested include demographic attributes, measures of childhood well-being, socioeconomic status, health behaviors, retirement, and health and functional status. Time-dependent data collected during the trajectory years will be included to reflect the dynamic nature of some of these variables among older adults. The investigators also plan to identify subsets of cohort members who experienced a major life event (e.g.: retirement) immediately prior to, or early in, the study interval and then characterize their drinking trajectories subsequent to that event. Prior research suggests alcohol use trajectories describing increasing levels of drinking, decreasing levels, stable use at both high and low levels, and abstinence will be identified. All of these trajectories have important implications for public health practice. Public health will benefit by using research findings to design more age-appropriate alcohol abuse prevention and health promotion interventions for the rapidly expanding older adult population. Public Health Relevance: This project is relevant to public health because it has important implications for adults ages 50 and older who comprise a rapidly increasing population segment in most communities. Alcohol use can have profound effects on older adults that are either harmful or beneficial depending in large part on how much is consumed overall and on individual occasions. The proposed cost-efficient research will using existing datasets to study changes in alcohol use behaviors over time among older adults and identify factors that may increase the likelihood of harmful drinking and decrease the likelihood of beneficial or moderate alcohol use.

描述（由申请人提供）：本研究的目标是支持公共卫生工作，以减少 50 岁及以上男性和女性与饮酒相关的问题。大量饮酒会增加发病率和早期死亡率，但适量饮酒可以降低某些类型心脏病的风险，从而为许多老年人带来健康益处。众所周知，许多老年人经常饮酒，并且酒精问题可能会在晚年出现，但很少有研究探讨这个异质群体的饮酒情况如何随着时间的推移而变化。这项纵向研究将使用来自全国代表性队列的四个现有数据集来识别和描述老年人的饮酒轨迹，这些数据集包括健康与退休研究 (HRS)、全国成熟女性纵向调查 (NLS)、NLS 年轻女性和该研究老年人的资产和健康动态（AHEAD）。在我们的研究期间（1995-2004 年），年轻女性群体的成员进入了人生的第 6 个十年。 NLS 老年男性和年轻男性队列缺乏合适的酒精数据。使用四个队列扩大了感兴趣的年龄范围，增加了要考虑的协变量的数量，并支持女性之间的复制分析。从 1995 年到 2004 年，所有队列均使用两组可比较的问题提供了 5 次酒精数据。将使用先前对青少年和年轻人饮酒行为产生新见解的方法来识别和表征酒精使用轨迹。潜在类别增长分析（基于半参数组的建模）和增长混合模型将以人为中心的定量方法与传统的以变量为中心的方法相结合。与风险概念模型的积累一致，要测试的协变量包括人口特征、儿童福祉指标、社会经济状况、健康行为、退休以及健康和功能状态。将包括在轨迹年中收集的与时间相关的数据，以反映老年人中某些变量的动态性质。研究人员还计划识别在研究间隔之前或早期经历过重大生活事件（例如：退休）的队列成员子集，然后描述他们在该事件之后的饮酒轨迹。先前的研究表明，描述饮酒水平增加、水平下降、高水平和低水平稳定使用以及戒酒的饮酒轨迹将被确定。所有这些轨迹对公共卫生实践都有重要影响。利用研究结果为迅速扩大的老年人口设计更适合年龄的酗酒预防和健康促进干预措施，将使公共卫生受益。公共卫生相关性：该项目与公共卫生相关，因为它对大多数社区中人口迅速增长的 50 岁及以上成年人具有重要影响。饮酒会对老年人产生深远的影响，这种影响是有害的还是有益的，这在很大程度上取决于整体和个人的饮酒量。拟议的成本效益研究将使用现有数据集来研究老年人饮酒行为随时间的变化，并确定可能增加有害饮酒可能性并降低有益或适度饮酒可能性的因素。
