DESCRIPTION (provided by applicant): From the mid-1970's to 1992, the prevalence rates of cigarette smoking among youth in the United States steadily decreased. However, these rates increased from 1992 and peaked in 1997. During the past five years, a steady decline in tobacco use among youth has again been observed. A similar pattern has also been observed in California. In this study, we will use secondary analysis of archival data from two youth tobacco surveys in California to determine whether this inverted V-shaped trend applies to various smoking behaviors (e.g., 30-day and weekly smoking behaviors) among youth in California. We will also examine the trends of cigarette use across different age groups and birth cohorts. Furthermore, we will identify several risk and protective factors of tobacco use (e.g., friends' smoking, social norms) and examine their patterns of change and impacts on tobacco use in the last ten years using two newly developed statistical approaches: age-period-cohort analysis and multilevel structural equation model. The proposed data sets (California Youth Survey and California Tobacco Youth Survey) to be analyzed in this project provide a rich array of cross-sectional data from 1990 to 2000. Each cross-sectional sample provides a replicated survey of tobacco use among youth in California. This project proposes to analyze the cross-sectional data using multiple regression, logistic regression, and structural equation models. Information obtained from the replicated cross-sectional samples provides a profile of changes across time. Furthermore, they can be studied using the multilevel approach to gain a better understanding of the long-term trend of tobacco use, changes in tobacco use-related psychosocial factors, and changes in the impacts of those factors on tobacco use across time. The project is important because it will identify factors associated with recent trends in cigarette smoking, which will help in specifying critical components for tobacco use prevention programs, leading to efficient and well-targeted prevention intervention programs for youth.

描述（由申请人提供）：从1970年代中期到1992年，美国青年吸烟的流行率稳步下降。然而，这些速度从1992年提高，并在1997年达到顶峰。在过去的五年中，在青年中再次观察到了烟草使用的稳步下降。在加利福尼亚州也观察到了类似的模式。在这项研究中，我们将使用来自加利福尼亚的两名青年烟草调查的档案数据进行二级分析，以确定加利福尼亚州青年中这种倒V形趋势是否适用于各种吸烟行为（例如，30天和每周吸烟行为）。我们还将研究不同年龄段和出生队列中香烟使用的趋势。此外，我们将使用两种新开发的统计方法来确定使用烟草使用的几种风险和保护性因素（例如，吸烟，社会规范），并检查其变化模式以及对烟草使用的影响：年龄 - period-cohort分析和多级结构方程模型。该项目中要分析的拟议数据集（加利福尼亚青年调查和加利福尼亚烟草青年调查）提供了一系列从1990年到2000年的横截面数据。每个横截面样本提供了对加利福尼亚州青年烟草使用的重复调查。该项目建议使用多元回归，逻辑回归和结构方程模型来分析横截面数据。从复制的横截面样本获得的信息提供了整个时间变化的概况。此外，可以使用多层次方法对它们进行研究，以更好地了解烟草使用的长期趋势，与烟草使用相关的心理社会因素的变化以及这些因素对整个时间烟草使用的影响的变化。该项目很重要，因为它将确定与吸烟的最新趋势相关的因素，这将有助于指定用于烟草使用预防计划的关键组成部分，从而为青年人提供有效且易于靶心的预防干预计划。
