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，北方平原美洲印第安人的烟草使用率最高。值得注意的是，与生活在其他地区的美洲印第安人和生活在北方平原和美国其他地区的非西班牙裔白人相比，北方平原美洲印第安人的烟草相关癌症发病率也更高。尽管在整个美洲印第安社区，人们都知道与烟草有关的癌症发病率升高，但北方平原美洲印第安成年人仍在继续吸烟。此外，患有癌症的北方平原美国印第安人患者尽管知道这种行为与癌症复发、新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）的使命是降低北方平原美洲印第安人的癌症死亡率。2002年，该项目的PI Petereit博士制定了“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，社区研究代表被聘请与位于保留地的夏延河苏族、罗斯巴德苏族、松岭拉科塔苏族以及拉皮德城城市印第安人社区合作。这项研究将集中在美国印第安人生活的夏延河，玫瑰花蕾和松树岭保留地。 拟议的项目“美国印第安人吸烟依赖性研究（PQ 4）”旨在回答研究问题，“为什么北方平原美国印第安人不改变已知会增加癌症风险的烟草使用行为？“这项研究是基于计划行为理论，并使用基于阶段的框架。移动保健（移动的保健），即使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，因为它为向农村和其他人口提供与保健有关的信息提供了一种低成本、高效率的方式。这对于本研究是可行的，因为北方平原美洲印第安人对无线技术的使用正在迅速增加。 该研究的具体目标是：目标1：测量预测北方平原美洲印第安人吸烟行为的因素;目标2：确定与北方平原美洲印第安人吸烟持续性和高复吸行为相关的问题和风险因素，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方平原美国印第安人。 结果数据将揭示戒烟意图、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禁欲将被确定。研究结果将影响北方平原美国印第安人的烟草使用，为这一人群设计有效的戒烟干预措施提供见解。

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.
