Individuals with chronic obstructive pulmonary disease (COPD) experience irreversible airflow obstruction, dyspnea, coughing, and fatigue. One of the goals of treating individuals with COPD is to improve their quality of life. The aim of this research was to evaluate the 2009 Texas Behavioral Risk Factor Surveillance System (BRFSS) as a method for surveillance of COPD by identifying factors associated with impaired health-related quality of life (HRQoL) among respondents with COPD as well as comment on differences between the COPD and non-COPD population in a state representative sample.
Data from 348 COPD respondents were obtained from the 2009 Texas BRFSS. The Andersen behavior model was used to categorize variables as predisposing characteristics, health behaviors, and health service utilization. Self-rated health (SRH) was the HRQoL indicator used in this analysis. Chi-square tests were used to examine differences between COPD and non-COPD respondents. The relation between SRH and risk factors were modeled using domain analysis and logistic regressions. All analyses incorporated the sample weights to be representative of the state population.
Adults with COPD reported significantly worse SRH than adults who did not have COPD (p < .001). Among respondents with COPD, the predisposing characteristics associated with impaired HRQoL were obesity, education, and asthma; the health practices and service utilization factors associated with HRQoL included smoking, physical inactivity, having a health plan, and the inability to see a doctor because of costs.
The Texas COPD population experienced increased risk of impaired SRH compared with the non-COPD population. The findings from our population-level survey study are similar to results observed at the clinical level.
患有慢性阻塞性肺疾病（COPD）的个体经历不可逆的气流阻塞、呼吸困难、咳嗽和疲劳。治疗 COPD 患者的目标之一是改善他们的生活质量。本研究旨在评估 2009 年德克萨斯州行为风险因素监测系统（BRFSS）作为监测 COPD 的方法，通过确定与 COPD 患者健康相关生活质量（HRQoL）受损相关的因素，以及评论在州代表性样本中 COPD 和非 COPD 人群之间的差异。
从 2009 年德克萨斯州 BRFSS 中获得了 348 名 COPD 受访者的数据。采用安德森行为模型将变量归类为倾向特征、健康行为和卫生服务利用。自我报告的健康（SRH）是本分析中使用的 HRQoL 指标。卡方检验用于检查 COPD 和非 COPD 受访者之间的差异。使用域分析和逻辑回归模型来分析 SRH 与危险因素之间的关系。所有分析均采用样本权重，以代表州人口。
患有 COPD 的成年人报告的 SRH 明显差于没有 COPD 的成年人（p <.001）。在 COPD 受访者中，与 HRQoL 受损相关的倾向特征包括肥胖、教育和哮喘；与 HRQoL 相关的健康实践和服务利用因素包括吸烟、身体活动不足、有健康计划以及因费用而无法看医生。
与非 COPD 人群相比，德克萨斯州 COPD 人群的 SRH 受损风险增加。我们的人群水平调查研究结果与临床水平观察到的结果相似。
