American Indian mHealth Smoking Dependence study (PQ4)

描述（由申请人提供）：与其他美洲印第安人和非西班牙裔白人相比，北部平原美洲印第安人的烟草使用量最高。值得注意的是，与生活在其他地区的美国印第安人以及生活在北部平原和美国其他地方的非西班牙裔白人相比，北部平原的美国印第安人患烟草相关癌症的比例也更高。尽管整个美洲印第安人社区都知道这些与烟草有关的癌症发病率升高，但北部平原的美洲印第安成年人仍在使用烟草。此外，美国北部平原印第安人癌症患者明知这种行为与癌症复发、新发癌症和其他慢性疾病有关，但仍继续吸烟。拉皮德城地区医院（RCRH）的使命是降低北部平原美洲印第安人的癌症死亡率。2002年，Petereit博士作为该项目的负责人，制定了“向前走”计划，旨在解决南达科他州西部部落之间的癌症差异。为了实现这一目标，我们聘请了社区研究代表，与居住在保留区的夏延河苏族、玫瑰花蕾苏族、松岭拉科塔苏族以及拉皮德城的印第安人社区合作。这项研究将重点关注居住在夏延河、玫瑰花蕾和松岭保留地的美国印第安人。拟议的项目“美国印第安人移动健康吸烟依赖研究（PQ4）”旨在回答研究问题，“为什么美国北部平原印第安人不改变已知会增加癌症风险的烟草使用行为？”本研究以计划行为理论为基础，采用基于阶段的框架。移动保健（移动保健），即利用手机等无线设备提供与保健有关的信息，将有助于实现项目目标，因为它提供了一种低成本、高效的方式，向农村和其他人口提供与保健有关的信息。这对于这项研究来说是可行的，因为无线技术在北部平原的美国印第安人中正在迅速增加。该研究的具体目的是：目的1：测量预测北部平原美洲印第安人吸烟行为的因素；目标2：确定与北部平原美洲印第安人吸烟持久性和高复发行为相关的问题和危险因素，无论是否了解吸烟危害；目标3：使用计划行为理论，开发和调整现有的戒烟干预措施，用于每天吸烟的成年北部平原美洲印第安人。结果数据将揭示戒烟意向、成功戒烟尝试和复吸的预测因素。其他社会认知变量，确保最初的戒烟尝试转化为长期的戒断将被确定。研究结果将通过为这一人群设计有效的戒烟干预措施提供见解，影响北部平原美洲印第安人的烟草使用。

DESCRIPTION (provided by applicant): Northern Plains American Indians have the highest tobacco use compared with other American Indians and non-Hispanic Whites. Notably, the rate for tobacco related cancers also are higher among Northern Plains American Indians as compared to American Indians living in other regions and for non-Hispanic Whites living in the Northern Plains and elsewhere in the US. Although awareness of these elevated rates of tobacco-related cancers is well known throughout American Indian communities, Northern Plains American Indian adults continue to use tobacco. In addition, Northern Plains American Indian patients with cancer continue to smoke despite knowing that this behavior is related to cancer recurrence, new cancers and other chronic illnesses. Rapid City Regional Hospital's (RCRH) mission is to reduce cancer mortality among American Indians in the Northern Plains. In 2002, Dr. Petereit, the PI for this project, developed the Walking Forward Program which is designed to address cancer disparities among Western South Dakota tribes. To accomplish this, Community Research Representatives have been hired to work with the reservation-based Cheyenne River Sioux, Rosebud Sioux, and Pine Ridge Lakota Sioux and the Rapid City urban Indian community. This study will focus on American Indians living on the Cheyenne River, Rosebud and Pine Ridge Reservations. The proposed project, "American Indian mHealth Smoking Dependence Study (PQ4)," is designed to answer the research question, "Why don't Northern Plain American Indians alter tobacco use behaviors known to increase the risk of cancer?" The study is based on the Theory of Planned Behavior and uses a phase- based framework. mHealth (mobile health), the use of wireless devices such as cell phones to provide health- related information, will facilitate attainment of project aims as it offers a low-cost, efficient way to provide health-related messages to rural and other populations. This will be feasible for this study as access to wireless technology is rapidly increasing among Northern Plains American Indians. The specific aims for the study are: Aim 1: Measure factors that predict smoking behaviors among Northern Plains American Indians; Aim 2: Identify issues and risk factors related to smoking persistence and high relapse behaviors, regardless of knowledge about smoking hazards, among Northern Plains American Indians; and Aim 3: Using the Theory for Planned Behavior, develop and adapt existing tobacco cessation interventions for use with adult Northern Plains American Indians who smoke cigarettes daily. Outcome data will reveal predictors of intention to quit smoking, successful quit attempts, and relapse. Other social cognitive variables that ensure initial quit attempts are translated into longer term abstinence wil be identified. Study results will impact tobacco use among Northern Plains American Indians by providing insight into designing effective cessation interventions for this population. PUBLIC HEALTH RELEVANCE: The prevalence of smoking among Northern Plains American Indians is of epidemic proportion and on the rise. Consequently, they also have high cancer mortality rates. This project is designed to understand continued tobacco use by Northern Plains American Indians despite knowledge of its cancer risks and to identify the types of interventions most effective for smoking cessation success in this population.
