Patterns of Physical Activity in Lung Cancer Survivors

描述（由申请人提供）：现有证据表明，癌症幸存者的体力活动水平较低。这增加了他们患一些慢性疾病的风险，作为癌症幸存者，他们可能已经处于更高的风险之中。此外，不活动可能会对癌症幸存者的健康相关生活质量产生不利影响。肺癌幸存者特别可能有低水平的体力活动，因为他们年龄较大，经常合并症，以及常见的疾病和治疗相关影响的经验。以前没有研究调查过肺癌幸存者的身体活动水平，他们占美国所有癌症幸存者的4%。我们在拟议的研究中解决了这一重要的知识差距。以前的一些研究已经开始研究与癌症幸存者身体活动水平相关的因素。有本研究的局限性，我们在肺癌幸存者的拟议研究中，通过检查一套全面的身体活动协变量来自社会认知理论，以前的实证研究结果，并考虑到肺癌幸存者的特点。这项研究的具体目的是：（1）建立肺癌幸存者的体力活动水平;（2）确定肺癌幸存者体力活动的协变量。在拟议的横断面研究中，200名肺癌幸存者将完成关于他们的体力活动水平和体力活动协变量的电话采访。此外，将从200名参与者中的30名获得基于加速度计的客观身体活动数据。这项拟议的研究将为设计未来的干预措施提供急需的知识基础，以增加肺癌幸存者的体力活动水平。研究结果还将揭示肺癌幸存者的亚组，他们可能最需要这种干预措施。此外，拟议研究的结果将提高目前对肺癌生存率的认识，这在新兴的生存率文献中代表性不足。

DESCRIPTION (provided by applicant): Available evidence indicates that cancer survivors have low levels of physical activity. This increases their risk for a number of chronic illnesses for which, as cancer survivors, they may already be at heightened risk. Additionally, inactivity may adversely impact cancer survivors' health-related quality of life. Lung cancer survivors are especially likely to have low levels of physical activity, given their older age, frequent comorbid conditions, and common experience of disease- and treatment-related effects. No previous research has examined the physical activity levels of lung cancer survivors, who comprise 4% of all cancer survivors in the United States. We address this important knowledge gap in the proposed study. Some previous research has begun to examine the factors associated with cancer survivors' physical activity levels. There are limitations of this research, which we address in the proposed study of lung cancer survivors by examining a comprehensive set of physical activity covariates drawn from social cognitive theory, previous empirical findings, and a consideration of the characteristics of lung cancer survivors. The specific aims of the proposed study are: (1) To establish the physical activity levels of lung cancer survivors; and (2) To identify covariates of physical activity among lung cancer survivors. In the proposed cross-sectional study, 200 lung cancer survivors will complete a telephone interview regarding their physical activity levels and covariates of physical activity. Additionally, accelerometer-based objective physical activity data will be obtained from 30 of the 200 participants. The proposed study will provide a much-needed knowledge base for the design of future interventions to increase lung cancer survivors' physical activity levels. The study results will also shed light on subgroups of lung cancer survivors for whom such interventions may be most needed. Additionally, the results of the proposed study will enhance current knowledge of lung cancer survivorship, which is underrepresented within the burgeoning survivorship literature.
