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加州韩国移民人群样本的烟草使用变化及其决定因素。这项建议将评估2,830名加州韩裔居民的烟草行为和预测因素的纵向变化，这些人在2001年4月至2002年10月完成的电话访谈中提供了基线数据。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的基线后约45个月通过额外的电话访谈进行评估，并在约27个月后进行第三次电话访谈。这将为加州韩国移民的烟草使用变化提供大约四年的随访评估。将招募一个新的1,200名受访者队列，并在基线和27个月时进行访谈，以评估我们最初的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”。该项目将探讨对当前烟草控制计划的看法、对美国社会的文化适应、对大众媒体和人际媒体的接触以及来自学习理论及其对“行为生态模型”的扩展的其他变量与戒烟、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。将特别关注反烟草媒体宣传戒烟和无烟家庭运动的影响。这项研究的结果将为韩国和其他移民人口的烟草控制理论和干预措施（包括社区范围的政策）的完善提供信息。该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ETS暴露的停止和减少，以便估计后续建议的效果大小。在该试点中获得的数据将为临床服务的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州范围内向广泛分布的韩国人口提供。综合分析将为韩裔居民的烟草控制研究提供信息，他们是加州和美国不断增长且服务不足的少数群体，它还将为分布在更大地理区域的其他亚洲和少数民族人口提供干预措施提供模式。

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.
