MN State & Local Programs Effects on Youth Tobacco Use

描述（由申请人提供）：本提案是一份关于“州和地方烟草项目对青少年烟草使用的影响”的续期申请，该项目于2000年由NCI根据一项特殊的RFA资助。由此产生的研究，被称为明尼苏达州青少年社区队列（MACC）研究，是一项基于人群的观察队列研究，包括2000-2001年登记的4295名12-16岁的青少年（3677名来自明尼苏达州，618名来自比较州），以及2001-2002年登记的668名明尼苏达州12岁的青少年。MACC研究的目的是对个人、家庭、社区和州一级对烟草使用的影响以及烟草吸收的轨迹进行多层次分析。明尼苏达州的参与者使用随机数字拨号方法进行抽样，并被嵌套在60个地缘政治单元（gpu）中。gpu是从整个州中选择的分层随机样本。每月约有720名参与者接受调查，以提供明尼苏达州烟草流行率的时间序列。目前的研究计划在6个时间点从每个队列成员收集有关吸烟行为、态度和环境的信息。在第六个数据收集点，队列的年龄在14岁到19岁之间。本研究建议继续对这个队列进行额外的8次观察，每个人（48个月的全州观察），最后的队列将年龄在18到23岁之间。扩展这个队列研究将使我们能够解决有关吸烟模式变化的重要问题，通过过渡到青年期，烟草控制政策的长期影响以及针对年轻人的干预措施。吸烟模式的队列差异以及对控烟努力的反应，以及继续分析当前拨款的数据。这项研究还为评估预计在2004财政年度及以后大幅减少各州烟草控制支出的影响提供了理想的条件。我们还建议对每个MN队列成员的父母进行一次性横断面调查，以便在多水平分析中增加有关家庭对吸烟吸收影响的有价值信息。

DESCRIPTION (provided by applicant): This proposal is a request for renewal of the grant entitled "Effects of State and Local Tobacco Programs on Youth Tobacco Use", funded by NCI in 2000 under a special RFA. The resulting study, called the Minnesota Adolescent Community Cohort (MACC) Study, is a population-based, observational cohort study that includes 4295 teenagers aged 12-16 when enrolled in 2000-2001 (3677 from Minnesota and 618 from comparison states), and an additional 668 Minnesota 12-year-olds enrolled in 2001-2002. The MACC Study is designed to allow multilevel analysis of the influences at the individual, family, community and state level on tobacco use and the trajectory of tobacco uptake. The Minnesota participants were sampled using Random Digit Dial methodology, and are nested in 60 geo-political units (GPUs). The GPUs are a stratified random sample that was selected from the entire state. About 720 participants are surveyed each month to provide a time-series of tobacco prevalence for Minnesota. The current study is scheduled to collect information about smoking behaviors, attitudes and environments from each cohort member at 6 points in time. At the sixth data collection point, the cohort will range in age from 14 to 19. This study proposes to continue to follow this cohort for an additional 8 observations on each individual (48 monthly statewide observations), at the end of which the cohort will be age 18 to 23, Extending this cohort study will allow us to address important questions about changes in smoking patterns through the transition to young adulthood, long-term effects of tobacco control policies and intervention efforts directed at youth, and cohort differences in smoking patterns and response to tobacco control efforts, as well as continue to analyze the data from the current grant. The study also is ideally positioned to assess the effects of the expected dramatic reductions in state tobacco control spending in fiscal year 2004 and beyond. We are also proposing to add a one-time cross-sectional survey of a parent of each MN cohort member to add valuable information about family influences on smoking uptake in the multilevel analyses.
