Little is known about how long-term weight gain affects the health perception of COPD patients. The aim is to evaluate the long-term association of BMI change and health-related quality of life (HRQoL) in obese COPD patients. Claims and survey data from a COPD disease management program were used to match two groups of COPD patients with BMI ≥ 30 who have differing weight trajectories over a 5-year timespan via propensity score and genetic matching. EQ-5D-5L, including visual analog scale (VAS) and COPD Assessment Test (CAT), were used as outcomes of interest. Sociodemographic and disease-based variables were matched. Out of 1202 obese COPD patients, 126 with a weight increase of four or more BMI points were matched separately with 252 (propensity score matching) and 197 (genetic matching) control subjects who had relatively stable BMI. For the EQ-5D-5L, patients with BMI increase reported significantly worse health perception for VAS and all descriptive dimensions except pain/discomfort. For the CAT, especially the perception of ability to complete daily activities and overall energy results were significantly worse. VAS differences reach the range of minimal important differences. Stopping smoking and already being in obesity class II were the most influential risk factors for BMI increase. Obese COPD patients who gain four or more BMI points over 5 years report significantly lower results in different dimensions of generic and disease-specific HRQoL than their peers with stable BMI. To improve real-world outcomes, tracking and preventing specific BMI trajectories could constitute a clinically relevant aspect of managing COPD patients.

参与疾病管理计划的肥胖 COPD 患者的长期体重增加:健康相关生活质量降低的风险因素

关于长期体重增加如何影响 COPD 患者的健康认知,我们知之甚少。目的是评估肥胖 COPD 患者 BMI 变化与健康相关生活质量 (HRQoL) 的长期关联。来自 COPD 疾病管理计划的索赔和调查数据用于通过倾向评分和遗传匹配匹配两组 BMI ≥ 30 的 COPD 患者,这些患者在 5 年的时间跨度内具有不同的体重轨迹。EQ-5D-5L,包括视觉模拟量表 (VAS) 和 COPD 评估测试 (CAT),被用作感兴趣的结果。社会人口统计学和基于疾病的变量相匹配。在 1202 名肥胖 COPD 患者中,126 名体重增加 4 个或更多 BMI 点的患者分别与 252 名(倾向评分匹配)和 197 名(基因匹配)BMI 相对稳定的对照受试者进行匹配。对于 EQ-5D-5L,BMI 增加的患者报告了对 VAS 和除疼痛/不适之外的所有描述性维度的健康感知显着更差。对于 CAT,尤其是对完成日常活动的能力和整体能量结果的感知明显更差。VAS 差异达到最小重要差异的范围。戒烟和已经处于肥胖等级 II 是 BMI 增加的最有影响的危险因素。在 5 年内获得 4 个或更多 BMI 点的肥胖 COPD 患者报告的通用和疾病特异性 HRQoL 的不同维度的结果显着低于 BMI 稳定的同龄人。为了改善现实世界的结果,跟踪和预防特定的 BMI 轨迹可能构成管理 COPD 患者的临床相关方面。BMI 增加的患者报告对 VAS 和所有描述性维度(除了疼痛/不适)的健康感知显着更差。对于 CAT,尤其是对完成日常活动的能力和整体能量结果的感知明显更差。VAS 差异达到最小重要差异的范围。戒烟和已经处于肥胖等级 II 是 BMI 增加的最有影响的危险因素。在 5 年内获得 4 个或更多 BMI 点的肥胖 COPD 患者报告的通用和疾病特异性 HRQoL 的不同维度的结果显着低于 BMI 稳定的同龄人。为了改善现实世界的结果,跟踪和预防特定的 BMI 轨迹可能构成管理 COPD 患者的临床相关方面。BMI 增加的患者报告对 VAS 和所有描述性维度(除了疼痛/不适)的健康感知显着更差。对于 CAT,尤其是对完成日常活动的能力和整体能量结果的感知明显更差。VAS 差异达到最小重要差异的范围。戒烟和已经处于肥胖等级 II 是 BMI 增加的最有影响的危险因素。在 5 年内获得 4 个或更多 BMI 点的肥胖 COPD 患者报告的通用和疾病特异性 HRQoL 的不同维度的结果显着低于 BMI 稳定的同龄人。为了改善现实世界的结果,跟踪和预防特定的 BMI 轨迹可能构成管理 COPD 患者的临床相关方面。
