Optimizing the Health of Korean Youth Using Technology for Smoking Cessation

项目总结（见说明）： 自20世纪60年代以来，协调一致的公共卫生努力使美国吸烟的总体流行率降低了约50%，其中加州等州的降幅甚至更大。 虽然这些努力值得称赞，并导致许多人的发病率和死亡率下降，但成果并不均等。在洛杉矶县，只有10.4%的居民吸烟，在经济和种族/民族差异的特定亚组中观察到惊人的高流行率。在洛杉矶县的韩裔美国人中，吸烟率达到40%，年轻人的吸烟率有所下降，但仍然很高。该研究项目建立在社区机构、学生和活动家、县政策制定者和学者的承诺基础上，为韩国青少年量身定制基于证据的戒烟干预措施，并制定程序，使用网络和移动的智能手机提供干预措施。本研究项目的第一阶段涉及咨询活动和焦点小组程序，以适应和定制为期6周的认知行为动机增强（CBME） 专门针对韩裔美国青年的戒烟干预。使用社区和学生的关键信息提供者和技术专家之间的迭代程序，适应性干预将被编程为使用网络提供。该研究项目的第二阶段涉及对寻求戒烟的韩裔美国青年（14-19岁）进行一项充分有效的随机对照试验，将网络上提供的实验性干预（n = 120）与标准护理（n= 120）进行比较。 主要结局变量是治疗结束时、24周和52周随访访视时通过生物标志物验证的7天时点戒烟率。我们预计实验组的戒烟率比对照组高2-3倍，这代表了显著的发病率降低。如果有效，干预措施也将为其他种族/种族的年轻吸烟者提供有效的适应计划。

PROJECT SUMMARY (See instructions): A concerted public health effort since the 1960s has reduced the overall prevalence of cigarette smoking in the United States by approximately 50%, with some states like California having even greater reductions. While these efforts are laudable and have led to reductions in morbidity and mortality for many, the gains have not been equal. In Los Angeles County, where only 10.4% of residents smoke cigarettes, alarmingly high prevalence is observed in select sub-groups that have economic and racial/ethnic disparities. Among Korean-Americans in Los Angeles County, smoking prevalence reaches 40% with reduced but still high rates of smoking among youth. This research project builds upon the commitment of community agencies, students and activists, County policymakers and academics to tailor an evidence-based smoking cessation intervention for use with Korean youth and to develop programming to deliver the intervention using the web and mobile Smartphones. The first phase of this research project involves consultative activities and focus group procedures to adapt and to tailor a 6-week, cognitive behavioral-motivational enhancement (CBME) cessation intervention specifically for Korean-American youth. Using iterative procedures between community and student key informants and technology experts, the adapted intervention will be programmed to be delivered using the web. The second phase of this research project involves conduct of an adequately powered, randomized controlled trial of the experimental intervention delivered on the web (n=120) compared to standard of care (n=120) for Korean-American youth (aged 14-19) seeking smoking cessation. Primary outcome variable is 7-day point prevalence of smoking abstinence verified by biomarkers at end of treatment, 24- and 52-week follow-up visits. We expect to find between 2-3 times increase in smoking cessation rates for the experimental group over the control group, which represents an outstanding morbidity reduction. If effective, the intervention will also provide an effective program for adaptation to young smokers of other ethnicities/races.
