The association between health-related quality of life (HRQoL; Short-Form Health Survey-12; SF-12) and patient-reported morbidity-related symptoms measured by the Patient Health Questionnaire-15 (PHQ-15) is analyzed in a representative sample of older people in the general German population. Data from 1,659 people aged 60 to 85 years were obtained. Latent class analysis identified six classes of patients, which optimally categorize clusters of physical symptoms the participants reported: musculoskeletal impairments (39.8%), healthy (25.7%), musculoskeletal and respiratory/cardiac impairments (12.8%), musculoskeletal and respiratory impairments, along with bowel and digestion problems (12.9%), general impairments (4.9%), and general impairments with no bowel and digestion problems (4.8%). The participants’ SF-12 Physical Health Scores (&eegr;2 = .39) and their Mental Health Scores (&eegr;2 = .28) are highly associated with these latent classes. These associations remain virtually identical after controlling for age. The results provide evidence that profiles of patient-reported physical impairments correspond strongly with reduced HRQoL independently from aging processes.

老年德国人代表性样本中的身体发病率与健康相关的生活质量的关联

在代表中分析了与健康有关的生活质量（HRQoL；短期健康调查-12； SF-12）与由患者健康问卷-15（PHQ-15）测量的患者报告的发病率相关症状之间的关联德国普通人群中的老年人样本。获得了1659名60至85岁的人的数据。潜在类别分析确定了六类患者，它们对参与者报告的身体症状群进行了最佳分类：肌肉骨骼损伤（39.8％），健康（25.7％），肌肉骨骼和呼吸/心脏损伤（12.8％），肌肉骨骼和呼吸障碍，以及有肠胃和消化问题（12.9％），一般性损伤（4.9％）和无肠胃和消化问题的一般性损伤（4.8％）。参与者的SF-12身体健康评分（＆eegr; 2 = .39）和他们的心理健康分数（＆eegr; 2 = .28）与这些潜在类别密切相关。在控制了年龄之后，这些关联实际上保持相同。结果提供了证据，表明患者报告的身体障碍的概况与HRQoL降低密切相关，而与衰老过程无关。
