Abstract：
This analysis was part of the Pain and Smoking Study (PASS), a randomized trial of a cognitive behavioral intervention (CBI) for Veterans with chronic pain who smoke. The objective of this study was to examine factors associated with participation in the walking component of the intervention. Demographics and clinical characteristics were obtained at baseline. Completion of two or more CBI counseling sessions was required to be included in analyses. Average daily step counts obtained via pedometer in the prior week were recorded in up to three telephone counseling sessions. Participants were then categorized as \"sedentary\" (≤ 4999 daily steps) or \"not sedentary\" (≥ 5000 daily steps). Multivariable logistic regression was used to model variance in activity categorization. Overall, 91.0% of participants were men, 70.5% were white, mean age was 58.4 years, mean BMI was 28.6, median pack years was 20.5, and 43.8% were depressed. Veterans reported moderate pain intensity (4.9/10) and pain interference (5.4/10). Pain locations included: lower extremity (67.4%), back (53.4%) and upper extremity (28.1%). Median daily steps were 2491 [IQR: 1720-3550] (sedentary) (n = 65), 7307 [IQR: 5952-8533] (not sedentary) (n = 24), and 3196 [IQR: 2237-5067] (overall) (n = 89). Veterans with older age (odds ratio (OR): 1.10, 95% confidence interval (CI): 1.04, 1.17) and presence of LE pain (OR: 5.98, 95% CI: 1.82, 19.65) had increased odds of being \"sedentary.\" Integrated smoking cessation and chronic pain self-management interventions that include a walking component may need to consider the impact of age and pain location on participation.Trial registration: The trial is registered at www.ClinicalTrials.gov (NCT02971137).

摘要：
这项分析是疼痛和吸烟研究（PASS）的一部分，一项针对吸烟的慢性疼痛退伍军人的认知行为干预（CBI）的随机试验。这项研究的目的是研究与参与干预措施的步行部分相关的因素。在基线时获得人口统计学和临床特征。需要在分析中包括两次或更多次CBI咨询会议的完成。在最多三个电话咨询会议中记录了前一周通过计步器获得的平均每日步数。然后将参与者分类为“久坐”（每天≤4999步）或“不久坐”（每天≥5000步）。使用多变量逻辑回归对活动分类中的方差进行建模。总的来说,91.0%的参与者是男性，70.5%为白色,平均年龄58.4岁,平均BMI为28.6,中位打包年数为20.5,43.8%的患者抑郁.退伍军人报告中等疼痛强度（4.9/10）和疼痛干扰（5.4/10）。疼痛部位包括：下肢（67.4%），背部（53.4%）和上肢（28.1%）。每日步数中位数为2491[IQR：1720-3550]（久坐）（n=65），7307[IQR：5952-8533]（不久坐）（n=24），和3196[IQR：2237-5067]（总体）（n=89）。年龄较大（比值比（OR）：1.10，95％置信区间（CI）：1.04，1.17）和存在LE疼痛（OR：5.98，95％CI：1.82，19.65）的退伍军人久坐的几率增加。“综合戒烟和慢性疼痛自我管理干预措施，包括步行部分可能需要考虑年龄和疼痛位置对参与的影响。试用登记：试用登记在www。ClinicalTrials.gov（NCT02971137）。首次发布于2016年11月22日。
