Smoking and ETS: California Residents of Korean Descent

描述（由申请人提供）：本申请的目的是评估以加利福尼亚韩国移民为基础的人群样本中烟草使用变化及其决定因素。该提案将评估烟草行为的纵向变化和预测因素，样本为2,830名加利福尼亚韩裔居民，他们在2001年4月至2002年10月完成的电话采访中提供了基线数据。吸烟状况的变化、环境烟草烟雾（ETS）暴露的变化以及住宅烟草政策（规则）的存在和执行的变化将在已经完成基线后约45个月进行一次额外的电话访谈，并在约27个月后进行第三次电话访谈。这项研究将对加州韩国移民的烟草使用变化进行为期四年的跟踪评估。将在基线和27个月时招募1200名新调查对象并对其进行访谈，以评估我们最初基线研究结果的普遍性，并复制烟草使用的短期变化和烟草使用变化的“决定因素”。该项目将探索当前烟草控制项目的认知程度、对美国社会的文化适应、对大众和人际媒体的接触，以及从学习理论及其对“行为生态模型”的延伸中得出的其他变量，与戒烟、开始吸烟、家庭吸烟政策以及成人和儿童的ETS接触的变化之间的关系。将特别注意宣传戒烟和无烟家庭的反烟草媒体运动的影响。本研究的结果将为改进韩国和其他移民人群的烟草控制理论和干预措施（包括社区范围的政策）提供信息。本申请还要求支持对电话咨询干预进行试点测试，以促进成人和儿童停止和减少ETS暴露，以便估计后续提案的效应大小。在该试点中获得的数据将为临床服务对照试验的研究设计提供信息，这些临床服务可能通过电话在全国范围内向分布广泛的韩国人口提供。这些综合分析将为针对韩裔居民的烟草控制研究提供信息，韩裔是加利福尼亚州和美国一个不断增长且服务不足的少数群体。它还将为向分布在更大地理区域的其他亚洲和少数群体提供干预措施提供模型。

DESCRIPTION (provided by applicant): The purpose of this application is to assess change and determinants of change in tobacco use for a population-based sample of California Korean immigrants. This proposal will assess longitudinal change in tobacco behaviors and predictors among a sample of 2,830 California residents of Korean descent who provided baseline data during telephone interviews completed from April 2001 through October 2002. Change in smoking status, change in environmental tobacco smoke (ETS) exposure, and change in the presence of and enforcement of residential tobacco policies (rules) will be assessed by an additional telephone interview about 45 months after the already completed baseline and a third telephone interview about 27 months later. This will provide about a four-year follow-up assessment of change in tobacco use among California Korean immigrants. A new cohort of 1,200 respondents will be recruited and interviewed at baseline and 27 months to assess the generalizability of our original baseline study results and to replicate short-term changes in tobacco use and the "determinants" of change in tobacco use. The project will explore the degree to which perceptions of current tobacco control programs, acculturation to U.S. society, exposure to mass and interpersonal media, and other variables derived from learning theory and its extension to the "Behavioral Ecological Model" are associated with changes in smoking cessation, initiation, home smoking policies, and adults' and children's ETS exposure. Particular attention will be devoted to the influence of the anti-tobacco media campaigns promoting smoking cessation and smoke-free homes. Results from this study will inform refinement of theory and interventions (including community-wide policies) for tobacco control with Korean and other immigrant populations. This application also requests support to pilot test a telephone counseling intervention to promote cessation and reduction in adults and children's ETS exposure in order to estimate effect sizes for a subsequent proposal. Data obtained in this pilot will inform research design for controlled trials of clinical services that might be delivered state-wide by telephone to the widely distributed Korean population. The combined analyses will inform tobacco control research for residents of Korean descent, who are a growing and underserved minority group in California and the U.S. It also will provide a model for delivering interventions to other Asian and minority populations distributed across larger geographic areas.
